Introduction
BlazeMaster® pipe and fittings are designed specifically for fire sprinkler systems. They are made from a specialty
thermoplastic known chemically as post-chlorinated polyvinyl chloride (CPVC). BlazeMaster® pipe and fittings provide
unique advantages in sprinkler installations including superior hydraulics, ease of joining, increased hanger spacing in
comparison to other thermoplastics and ease of assembly. They also are based on a technology with a continuous and
proven service history of more than 50 years.
This installation manual provides instructions for handling and installing a BlazeMaster® fire sprinkler system as well as
information regarding system design. It is intended as a supplement to basic, fundamental knowledge relating to the
installation and/or repair of CPVC fire sprinkler systems. Before commencing installation, a user should understand and
confirm applicable Australian Standards and local installation requirements for CPVC fire sprinkler systems.
BlazeMaster® CPVC pipe manufactured by Paratech Co LTD and supplied by Ampac Safety in sizes 20mm through 80mm
carries the markings of Underwriters Laboratories, Inc. (UL & C-UL).
For additional information regarding the BlazeMaster® product line, please refer to the internet website,
www.BlazeMaster.com. The most current product compatibility information, the BlazeMaster® Blaster newsletter, and
other BlazeMaster® fire sprinkler systems information can be found at this site.
Combination of BlazeMaster® Products with Other CPVC and Solvent Cements
All BlazeMaster® pipe, fittings and solvent cements have been evaluated and are listed for combination regardless of the
licensed manufacturer that produces the products.
Ampac Safety recommends the use of FESCO solvent cements. The assembly and curing instructions referenced in this
manual must be used.
Where Can BlazeMaster® Fire Sprinkler Systems Be Used?
BlazeMaster® CPVC pipe and fittings manufactured by Paratech Co LTD and are Listed by Underwriters Laboratories (UL
& C-UL). BlazeMaster® pipe and fittings therefore are compliant with the requirements of AS 4118.2.1 for installation in
accordance with AS 2118.9 – which permits the use of Blazemaster ® in residential systems to AS 2118.4, Domestic
(Home sprinkler) systems to AS 2118.5 and Light Hazard systems to AS 2118.1 along with the mechanical plant,
service and storage areas associated with these occupancies that are defined as Ordinary Hazard 1.
BlazeMaster® can also be used as system risers in residential buildings up to four storeys in height, refer to AS 2118.4 and
AS 2118.5
Refer also UL Fire Protection Equipment Directory, categories VIWT and HFYH.
BlazeMaster® fire sprinkler systems shall be employed in wet-pipe systems. (A wet-pipe system contains water and is
connected to a water supply so that the water will discharge immediately when the sprinkler is opened).
BlazeMaster® CPVC pipe supplied by Ampac Safety must never be used in a system using compressed air or other
gases.
Australian Standards must be referenced and followed for design and installation requirements in conjunction with this design
manual;
AS 2118.1 Automatic fire sprinkler systems - General systems
AS 2118.4 Sprinkler systems for accommodation buildings not exceeding four storeys in height
AS 2118.5 Home fire sprinkler systems
Page 3
Temperature/Pressure Rating
BlazeMaster® pipe and fittings 20mm – 80mm are rated for continuous service of 1207kPa at 65°C. BlazeMaster® pipe and
fittings are suitable for use in areas where ambient temperatures are within the range of 2°C to 65°C. BlazeMaster® pipe
and fittings may be installed in an area, such as a concealed space, where the temperature will exceed 65°C if ventilation is
provided or if insulation is used around the pipe to maintain a cooler environment. BlazeMaster® fire sprinkler systems must
be laid out so that the pipe and fittings are not closely exposed to devices that generate heat in excess of 65°C such as
light fixtures, ballasts and steam lines. If the installation is in an area subject to freezing temperatures, the sprinkler system
must be protected from freezing. A frozen system will not only be deactivated, but the pressures that may build up can
cause the sprinkler heads to open or damage the pipes.
Concealed Installations
In a concealed installation the minimum protection shall consist of:
 one layer of 9.5mm gypsum wallboard, or
 a suspended membrane ceiling with lay-in panels or tiles having a weight of not less than 1.7kg per square meter when
installed with metallic support grids, or
 12.7mm plywood soffits.
For residential occupancies defined in AS2118.1, AS2118.4 and AS2118.5, the minimum protection may consist of
one layer of 12.7mm plywood. During periods of renovation, appropriate steps must be taken to protect the piping
from fire exposure if the ceiling is temporarily removed.
Sprinkler Head Temperature Ratings
BlazeMaster® pipe and fittings supplied by Ampac Safety shall be used in sprinkler systems employing sprinkler heads
rated 107°C when installed concealed (protected) in accordance with the Listing. Sprinkler temperature ratings for exposed
installations are indicated in the individual sections of this manual.
Exposed Installations (Where Sprinklers are Required)
Note: It is always acceptable to install BlazeMaster® products in areas where sprinklers are not required.
As an alternative to the protection requirements, BlazeMaster® CPVC pipe and fittings may be installed without protection
(exposed) when subject to the following additional limitations:

Combustible Concealed Installations
Specially listed sprinkler heads exist that are listed for use with BlazeMaster® products in combustible concealed spaces
requiring sprinklers. When using BlazeMaster® products in these applications always follow the sprinkler head
manufacturers’ installation guidelines.
BlazeMaster® pipe and fittings must never be installed in combustible concealed spaces requiring sprinklers. Where
AS2118.4 and AS2118.5 permit the omission of sprinklers from combustible concealed spaces and BlazeMaster® pipe and
fittings may be installed in these areas when sprinklering residential occupancies according to these standards.
System Risers in AS 2118.1, AS 2118.4 and AS 2118.5 Applications
BlazeMaster® CPVC pipe and fittings may be used as system risers in accordance with AS 2118.1, AS 2118.4 and AS
2118.5 when subject to the following limitations:
Page 5
1. When installed protected (concealed), the minimum protection shall consist of either one layer of 9.5mm thick gypsum
wallboard or 12.7mm thick plywood.
2. When installed without protection (exposed), the following limitations shall apply:
Note: Only AS 2118.4 and AS 2118.5 applications may be installed without protection (exposed).
a) The riser shall be installed below a smooth, flat, horizontal ceiling construction. A Listed residential pendent sprinkler is
to be installed with its deflector at the distance from the ceiling specified in the sprinkler Listing.
b) A Listed residential pendent sprinkler is to have a maximum temperature rating of 68°C and a minimum K-factor of 3.0
and is to be installed at a maximum horizontal distance of 300mm from the centerline of the riser. The system is to be
designed based upon the Listed flows for the sprinkler selected except that the flow for a single sprinkler or for multiple
sprinklers flowing is to be not less than 41.64lpm per sprinkler.
c) The riser shall be supported vertically within 600mm of the ceiling or bottom of the joist.
d) The minimum riser diameter shall be 25mm and the maximum riser diameter shall be 50mm.
e) The maximum distance between the wall(s) and the outside surface of the riser pipe shall be 32mm.
f) All solvent cement joints shall be made with BlazeMaster® One Step Solvent Cement.
3. The BlazeMaster® CPVC sprinkler pipe and fittings shall be installed per these installation instructions.
4. Risers shall be supported by pipe clamps or by hangers located on the horizontal connection close to the riser. Only
Listed hangers and clamps shall be used.
5. Vertical lines must be supported at intervals, described in 7 & 8 below, to avoid placing excessive load on a fitting at the
lower end. Do this by using riser clamps or double bolt pipe clamps Listed for this service. The clamps must not exert
compressive stresses on the pipe. It is recommended that the clamps should be located just below a fitting so that the
shoulder of the fitting rests against the clamp. If necessary, a coupling can be modified and adhered to the pipe as a
bearing support such that the shoulder of the fitting rests on the clamp. Follow the recommended cure time.
WARNING: Modified riser collar shall only be used to provide support to the riser and shall not be used to join two pieces of
pipe.
6. Do not use riser clamps that squeeze the pipe and depend on compression of the pipe to support the weight.
Page 6
7. Hangers and straps shall not compress, distort, cut or abrade the piping and shall allow for free movement of the pipe to
allow for thermal expansion and contraction.
8. Maintain vertical piping in straight alignment with supports at each floor level, or at 3.05m intervals, whichever is less.
9.CPVC risers in vertical shafts or in buildings with ceilings over 7.62m, shall be aligned straightly and supported at each
floor level, or at 3.05m intervals, whichever is less.
Underground Water Pressure Service
Both pipe and fittings may be used in underground water pressure service installations per the following requirements:
1. AS 3500.1 and AS 2118.9.
2. The BlazeMaster® CPVC sprinkler pipe and fittings shall be installed a s per these installation instructions.
Thrust Blocking
If thrust blocks are utilized they should be designed per AS 3500.1.
Note: BlazeMaster® fire sprinkler systems utilize a solvent cement joining method. As such, thrust blocks are not required
with BlazeMaster® CPVC pipe and fittings in underground water pressure service. Reference AS3500.1.
The trench should be of adequate width to allow convenient installation, while at the same time being as narrow as
possible. Minimum trench widths may be utilised by joining pipe outside of the trench and lowering it into the trench after
adequate joint strength has been achieved. (NOTE: Refer to the recommended set and cure time tables for solvent cement
joints). Trench widths will have to be wider where pipe is joined in the trench or where thermal expansion and contraction is
a factor. See section titled “Snaking of Pipe”.
 Water filled pipe should be buried at least 300 mm below the maximum expected frost line.
 It is recommended that BlazeMaster® piping be run within a metal or concrete casing when it is installed beneath
surfaces that are subject to heavy-weight or constant traffic such as roadways and railroad tracks.
The trench bottom should be continuous, relatively smooth and free of rocks. Where ledge rock, hardpan or boulders are
encountered, it is necessary to protect the pipe from damage. Use a minimum of 100 mm of clean soil, sand, crushed stone
or other approved material as referenced in AS 3500.1.
Sufficient cover must be maintained to keep external stress levels below acceptable design stress. Reliability and safety of
service is of major importance in determining minimum cover. Local, state and national codes may also govern.
Snaking of Pipe
After BlazeMaster® CPVC pipe has been solvent welded, it is advisable to snake the pipe according to the below
recommendations beside the trench during its required curing time. BE ESPECIALLY CAREFUL NOT TO APPLY ANY
STRESS THAT WILL DISTURB THE UNDRIED JOINT. This snaking is necessary in order to allow for any anticipated
thermal movement that could take place in the newly joined pipeline.
Page 7
Snaking is particularly necessary on the lengths that have been solvent welded during the late afternoon of a hot day,
because their drying time will extend through the cool of the night when thermal contraction of the pipe could stress the
joints to the point of pull out.
This snaking is also especially necessary with pipe that is laid in its trench (necessitating wider trenches than
recommended) and is back-filled with cool earth before the joints are thoroughly dry.

Backfilling
Note: Underground pipe shall be thoroughly inspected and tested for leaks prior to backfilling. Backfill material
should be placed over pipe sections only, leaving the joints exposed during testing.
Ideally, backfilling should only be done early in the morning during hot weather when the line is fully contracted and there is
no chance of insufficiently dried joints being subjected to contraction stresses.
The pipe should be uniformly and continuously supported over its entire length on firm, stable material. Blocking should not
be used to change pipe grade or to intermittently support pipe across excavated sections.
Pipe is installed in a wide range of sub-soils. These soils should not only be stable but applied in such a manner to
physically shield the pipe from damage. Attention should be given to local pipe laying experience that may indicate
particular pipe bedding problems.
Backfill materials free of rocks with a particle size of 12mm or less should be used to surround the pipe with 150mm to
200mm of cover. It should be placed in layers. Each soil layer should be sufficiently compacted to uniformly develop lateral
passive soil forces during the backfill operation. It may be advisable to have the pipe under hydraulic pressure 103 –
172kPa during the backfilling.
Vibratory methods are preferred when compacting sand or gravel. Best results are obtained when the soils are in a nearly
saturated condition. Where water flooding is used, the initial backfill should be sufficient to insure complete coverage of the
pipe. Additional material should not be added until the water flooded backfill is firm enough to walk on. Care should be
taken to avoid floating the pipe.
Page 8
Sand and gravel containing a significant proportion of fine-grained material, such as silt and clay should be compacted by
hand or, preferably by mechanical tamper.
The remainder of the backfill should be placed and spread in approximately uniform layers in such a manner to fill the
trench completely so that there will be no unfilled spaces under or about the rocks or lumps of earth in the backfill. Large or
sharp rocks, frozen clods and other debris greater than 100mm in diameter should be removed. Rolling equipment or
heavy tampers should only be used to consolidate the final backfill.

Thermal Expansion and Contraction
BlazeMaster® CPVC pipe, like all piping materials, expands and contracts with changes in temperature. The coefficient of
linear expansion is 0.000068 cm / cm °C. Lineal expansion is the same for all pipe diameters.
A 4°C change in temperature will cause an expansion of 25mm for a 30.5m straight run of BlazeMaster® pipe.
For most operating and installation conditions, expansion and contraction can be accommodated at changes in direction of
the pipe run. However in certain instances, expansion loops or offsets may be required when installing long, straight runs of
pipe.

Pipe Deflection
BlazeMaster® fire sprinkler piping is inherently ductile allowing it to be deflected, within permissible limits, around or away
from objects during installation, which can reduce installation time. This ductility allows for greater freedom of design and
lower installed cost. The maximum installed deflections for BlazeMaster® piping are as follows:

Handling and Storage
BlazeMaster® CPVC is a tough, corrosion resistant material, but does not have the mechanical strength of steel.
Reasonable care must be exercised in handling BlazeMaster® pipe and fittings. They must not be dropped or have objects
dropped on them. If improper handling results in scratches, splits, or gouges, the damaged section shall be cut out and
discarded.
BlazeMaster® pipe must be covered with a nontransparent material when stored out of doors for extended periods of time.
Brief exposure to direct sunlight on the job site may result in color fade but will not affect physical properties. BlazeMaster®
fittings should be stored in their original containers to keep them free from dirt and reduce the possibility of damage.
Caution should be taken not to over stack boxes of BlazeMaster® fittings in extreme temperature environments (>65°C).
Joining BlazeMaster® CPVC Pipe and Fittings with One-Step Solvent Cement
Notice: Read and understand all instructions prior to assembly. Follow all instructions. Failure to follow instructions during
joining and testing may result in pipe failure, clogged waterways, or leakage.
Cutting
BlazeMaster® CPVC pipe can be easily cut with a ratchet cutter, a wheel-type plastic tubing cutter, a power saw or a fine
toothed saw. Tools used to cut CPVC must be designed for plastic use and must be in good condition in accordance with
the tool manufacturer’s recommendations. It is important to cut the pipe square. A square cut provides the surface of the
pipe with maximum bonding area.
Notice:
Avoid splitting the pipe when using ratchet cutters. Failure to do so may result in pipe failure or leakage.
 Only use ratchet cutters that contain a sharp blade (blades dull quickly).
 Only use ratchet cutters at temperatures of 10°C or warmer.
 Only use well-maintained, good quality ratchet cutters capable of consistently cutting the pipe squarely.
If any indication of damage or cracking is evident at the pipe end, cut off at least 50 mm beyond any visible crack.
Deburring & Beveling
Burrs and filings can prevent proper contact between pipe and fitting during assembly, and must be removed from the
outside and the inside of the pipe. A chamfering/ reaming tool or a file is suitable for this purpose. A slight bevel
(approximately 10° to 15°) shall be placed at the end of the pipe to ease entry of the pipe into the socket. This will minimize
the chance that the edges of the pipe will wipe solvent cement from the fitting socket during the insertion of the pipe.
Solvent Cement Application
Caution:
Prior to using approved BlazeMaster® fire sprinkler CPVC solvent cements, review and follow all precautions found on the
container label. This material is hazardous according to health criteria of Safe Work Australia. Hazard Category: T Toxic Xi
Irritant. Refer to the MSDS for safe handling precautions.
Using a clean, dry rag, wipe loose dirt and moisture from the fitting socket and pipe end. Moisture can slow the cure time
and at this stage of assembly, excessive water can reduce joint strength.
The pipe should enter the fitting socket easily one-third to two-thirds of the way. Contact between the pipe and fitting is
essential in making a good joint. This contact allows the solvent cement (which is applied in the next step) to effectively join
the pipe and fitting.
Page 13
Use a dauber that is properly sized for the pipe. For 20mm and 25mm pipe, use a dauber that is 12.7mm in size. For
32mm through 80mm pipe, use a dauber that is 19.1mm in size.
Only use FESCO solvent cements that have been specifically formulated and listed/approved for use with CPVC fire
sprinkler systems and approved by the pipe and fitting manufacturers.
Vigorously apply a heavy, even coat of cement to the outside pipe end. Apply a medium coat to the fitting socket. Pipe
sizes 32mm and above shall always receive a second cement application on the pipe end. FIRST APPLY CEMENT ON
THE PIPE END, THEN IN THE FITTING SOCKET, AND, FINALLY, ON THE PIPE END AGAIN.
Notice
Too much solvent cement can cause clogged waterways or weaken the wall of the pipe or fitting and result in pipe failure
or leakage.
 Do not allow excess cement to puddle in the pipe and fitting assembly. To prevent this puddling, apply a lighter coating
of solvent cement to the inside of the fitting socket than the outside of the pipe.
 Wipe off excess cement on the outside of the joint. The solvents will evaporate, but the solvent cement inside the fitting
will stay there.
Special care shall be exercised when assembling CPVC fire sprinkler systems in temperatures below 4°C. In colder
temperatures extra time must be allowed for the solvent cement to set and cure. Extra care should be taken to prevent
damaging the pipe during handling. When solvent welding pipe and fittings in colder temperatures, make certain that the
cement has not become lumpy or has “gelled”. Gelled cement must be discarded.
At temperatures above 27°C make sure both surfaces to be joined are still wet with cement during assembly. Higher
temperatures and/or wind accelerate the evaporation of the volatile solvents in the cement. Pipe stored in direct sunlight
may have surface temperatures 10°C to 15°C above the air temperature. If possible store the pipe and fittings, or, at least,
the ends to be solvent welded, out of the direct sunlight prior to cementing. The solvents will penetrate hot surfaces more
deeply. In conditions like this it is very important to avoid puddling the solvent cement inside the fitting socket.
Assembly
After applying cement, immediately insert the pipe into the fitting socket, while rotating the pipe one-quarter turn until the
pipe bottoms out at the fitting stop. Rotate the pipe as it is inserted into the fitting, not after it has bottomed out in the fitting.
Properly align the fitting for the installation at this time. Pipe must bottom to the stop. Hold the assembly for 30 seconds to
ensure initial bonding. A bead of solvent cement should be evident around the pipe and fitting juncture. If this bead is not
continuous around the socket shoulder, it may indicate that insufficient cement was applied. If insufficient cement is
applied, the fitting must be cut out and discarded. Cement in excess of the bead should be wiped off with a rag.
Notice:
Failure to allow sprinkler fitting joints to cure before installing sprinklers may result in cement in the sprinkler waterway.
 Install sprinkler heads only after all the CPVC pipe and fittings, including the sprinkler adapters, are solvent welded and
allowed to cure for a minimum of 30 minutes.
 Do not install sprinklers in the fittings prior to the fittings being cemented in place.
Exercise care when installing sprinklers. Allow sprinkler head fittings and previously joined fittings to cure for a minimum of
30 minutes prior to installing the sprinkler. When installing sprinklers, be sure to anchor or hold the pipe drop securely to
avoid rotating the pipe in previously cemented connections.
Page 14
Notice:
 Too much solvent cement can cause clogged waterways.
 Visually inspect sprinkler fittings to ensure that the waterway and threads are clear of any excess cement.
 Once the installation is complete and cured per Table I, II or III, hydrostatically test the system.
Set and Cure Times
Notice:
Inadequate curing of solvent cement joints may cause pipe failure or leakage. Solvent cement set and cure times are a
function of pipe size, temperature, relative humidity, and tightness of fit.
Cure times should be increased when moisture is present such as during cut-ins to live sprinkler lines. (NOTE: A specific
procedure for modifications or repairs to existing CPVC fire sprinkler lines is included in this manual.) The assembly must
be allowed to set, without any stress on the joint, for 1 to 5 minutes, depending on pipe size and temperature. Following the
initial set period, the assembly can be handled carefully, avoiding significant stresses to the joint.
Refer to Tables I, II, and III for MINIMUM cure times prior to pressure testing.

temperature must be raised to a temperature of 4.5°C or above and allowed to cure per the above recommendations prior
to pressure testing.
Page 15
System Acceptance Testing (Hydrostatic Pressure Test) Warning:
Never use air or compressed gas for system acceptance testing (hydrostatic pressure test). System failure when using
compressed air or gas for system acceptance testing may result in property damage, serious injury, or death.
Once an installation is completed and joints are properly cured per the above recommendations, the system should be pressure
tested with water to the requirements of AS 2118.1, AS 2118.4 or AS 2118.5 as applicable. See table I, II and III for curing
conditions for different hydrostatic test pressures. Table should not be interpolated for other pressures. Use the next highest
hydrostatic test pressure table.
When pressure testing, the sprinkler system shall be slowly filled with water and the air bled from the highest and farthest
sprinkler heads before pressure testing is applied. Air must be removed from piping systems (plastic or metal) to prevent it
from being locked in the system when pressure is applied. Entrapped air can generate excessive surge pressures that can
result in bodily injury and/ or property damage, regardless of the piping materials used.
If a leak is found, the fitting must be cut out and discarded. A new section can be installed using couplings or a union.
Unions should be used in accessible areas only.

Cut-In Procedure for System Modification or Repairs
At times it may become necessary to make modifications to existing CPVC fire sprinkler systems. This can be done safely
when the proper procedures are followed. The following procedure has been developed to assure that the modifications
are done successfully.
Prior to making system cut-ins on existing systems, care should be used to review proper joining procedures and to
FOLLOW CUT-IN CURE SCHEDULES to ensure the highest system integrity. Several methods can be utilised to tie into
an existing system using a socket style tee fitting in combination with the use of socket unions, grooved coupling adapters,
and flanges. Regardless of the method used, the following points must be followed to ensure the highest integrity:
 Using proper tools, the cut-in should be made on the smallest diameter pipe section (that is capable of adequately
supplying the system changes) in close proximity to the modification being made. This approach will expedite cure times
prior to pressure testing.
 The cut-in connection to the existing system should be made first, prior to proceeding with additional work.
Page 16
 Existing lines must be drained adequately prior to solvent cementing. Use a Drain Vac unit to be sure all water is
removed from the system (moisture can slow the cure time and reduce joint strength). One method to verify that the water
has been drained from the system is to remove the sprinkler heads on each side of the cut-in and allow any remaining
water to drain.
 Carefully review and follow the solvent cementing procedures for proper joining techniques prior to commencing with
cut-in (pipe must be cut square to proper length, deburred, beveled and dry to ensure proper insertion depth and highest
integrity).
 Carefully measure and cut pipe to proper length to ensure complete insertion during assembly (check the interference fit
of the components being joined).
 Note: During assembly of the cut-in tee (and other components) it is important to make a one-quarter turn when
inserting the pipe into the fitting per the assembly instructions, particularly on 32mm pipe sizes and larger. This may require
the use of several components assembled in combination with the cut-in tee to create a short spool piece assembly.
 This can be accomplished by using socket unions, flanges, or grooved coupling adapters that will ensure that a onequarter turn can be obtained on all pipe connections being joined.
 Prior to applying the solvent cement, use a clean dry rag to wipe moisture and dirt from the fitting socket and the pipe
end (the presence of moisture on the joining surfaces will reduce joint integrity).
 Use a new can of solvent cement when making cut-in connections (verify expiration dates stamped on can prior to use).
 After all work is completed, the cut-in joints must be allowed to cure properly prior to pressure testing as shown in the
table below.
 After work is completed and cut-in cure times are met, inspect work for proper alignment and hanger placement prior to
pressure testing.
 After cut-in cure times are met, the system must be slowly filled with water and the air bled from the furthest and highest
sprinkler heads before test pressure is applied (refer to the installation instructions regarding Hydrostatic Testing).
 After cut-in cure times are met and the air is bled from the system, it is recommended that portion of the sprinkler
system containing the cut-in tee be pressure tested. Prior to pressure testing, the system must be sectioned off to its
smallest area using floor valves, etc., to isolate the cut-in area. It is further recommended that the test pressure applied
should not exceed 50 psi over the system pressure. This approach will minimize the potential for water damage should a
leak occur. WARNING: AIR OR COMPRESSED GAS MUST NEVER BE USED FOR PRESSURE TESTING

Hangers and Supports
Because BlazeMaster® pipe is rigid, it requires fewer supports than flexible plastic systems. The support spacing is shown
in the following table.

3.0m
The pipe hangars must comply with the requirements of AS 2118.9.
Most hangers designed for metal pipe are suitable for BlazeMaster® pipe. Do not use undersized hangers. Hangers with
sufficient load bearing surface shall be selected based on pipe size, i.e. 32mm hangers for 32mm pipe. The hanger shall
not have rough or sharp edges that come in contact with the pipe. The pipe hangers must comply with the requirements of
AS 2118.9. For Quick Response upright sprinkler heads, rigid hangers secured to the ceiling shall be used.
Horizontal runs of BlazeMaster® pipe shall be braced so that the stress load (caused by bending the pipe) will not be placed
on a fitting or joint. See the Pipe Deflection section and tables.
When a sprinkler head activates, a significant reactive force can be exerted on the pipe. With a pendent head, this reactive
force can cause the pipe to lift vertically if it is not properly secured, especially if the sprinkler drop is from small diameter
pipe. The closest hanger shall brace the pipe against vertical lift-up.
Any of a number of techniques can be used to brace the pipe. Four acceptable approaches would be to use a standard
band hanger positioning the threaded support rod to 1.6mm above the pipe, a split-ring hanger, a wrap-around U hanger,
or a special escutcheon which prevents upward movement of the sprinkler through the ceiling.

Penetration of Studs and Joists
Wooden Studs and Joists
It is acceptable to cut holes in wood studs for support. The holes should be oversized to allow for movement.
Metal Studs
BlazeMaster® pipe and fittings should be protected from sharp edges when passing through metal studs.
Transition to Other Materials
Support
Additional support should be added at the metal side of a BlazeMaster® CPVC-metal transition to support the weight of
the metal system.
Threaded Connections
BlazeMaster® CPVC male and female threaded adapters or flanges are listed for connecting a BlazeMaster® fire
sprinkler system to other materials, valves, and appurtenances.
A thread sealant shall be used in making threaded connections. TFE (Teflon®) thread tape is the recommended sealant.
Some thread sealants other than TFE thread tape contain solvents or other materials that may be damaging to
CPVC. Always consult with the manufacturer of the material for compatibility with BlazeMaster® CPVC pipe and
fittings or reference the Chemical Compatibility and FGG/BM/CZ™ System Compatible program sections of
www.lubrizol.com/BuildingSolutions/BlazeMaster.html for additional information.
Care shall be exercised when transitioning between BlazeMaster® pipe and fittings and metal. Care must be taken to
avoid over-torquing.
Flanged Connections
Flange Make-Up: Once a flange is joined to pipe, the method for joining two flanges is as follows:
1. Piping runs joined to the flanges must be installed in a straight line position to the flange to avoid stress at the flange
due to misalignment. Piping must also be secured and supported to prevent lateral movement that can create stress and
damage the flange.
2. With gasket in place, align the bolt holes of the mating flanges by rotating the ring into position. (Consideration should
be given to alignment of one-piece flange prior to joining with pipe.)
3. Insert all bolts, washers (two standard flat washers per bolt), and nuts.
4. Make sure the faces of the mating surfaces are flush against gasket prior to bolting down the flanges.
Page 19
5. Tighten the nuts by hand until they are snug. Establish uniform pressure over the flange face by tightening the bolts in
6.8 Newton-m increments according to the sequence shown in Figure 8: Bolt Tightening Sequence following a 180°
opposing sequence.
6. Care must be taken to avoid “bending” the flange when joining a flange to a “raised face” flange, or a wafer-style
valve. Do not use bolts to bring together improperly mated flanges.
Caution: Over-torquing will damage the flange.
Torque given is for dry, non-lubricated bolt, standard washers, grade E EPDM 3.18mm thick full face gasket. If lubricant
(non-petroleum based) is used, torque levels may vary. Actual field conditions may require a variation in these
recommendations.

The following procedures are recommended for proper assembly of the Grooved Coupling Adapter.
READ THESE INSTRUCTIONS CAREFULLY BEFORE BEGINNING INSTALLATION.
1. Inspect the fittings and pipe to insure that they are sufficiently free from indentations, projections or roll-marks on the
gasket seating areas of the fitting and pipe. The pipe should be squarely cut with any loose scale, paint, and/or dirt
removed from the groove and seating surface. Use a standard grade E*, EPDM compound that is suitable for wet
fire sprinkler service. A flexible coupling shall be used with grooved coupling adapters. Caution: Use of rigid
style couplings may damage the grooved coupling adapter. Consult the coupling manufacturer for proper
selection.
*See manufacturer for temperature ratings.
2. Make sure the gasket is clean and free of any cracks, cuts or other defects which may cause leaks. Lubricate the
gasket with a vegetable soap-based gasket lubricant. Caution: Use of petroleum based lubricants will damage the
gasket and adapter resulting in stress failure of the CPVC adapter. A gasket/joint lubricant is recommended to
prevent pinching the gasket and to assist in seating the gasket during the alignment process. Apply the
appropriate lubricant to the gasket lips and exterior surface of the gasket.

3. Place the gasket over the metal pipe ends, being sure gasket lip does not overhang the pipe end. Insert the CPVC
grooved coupling adapter into the gasket. Make sure that the gasket is centered between the two grooves. No portion of
the gasket should extend into the grooves. Caution: Make sure the gasket is not pinched between the pipe and the
fitting.
4. Place the metal housing over the gasket, making sure the metal housing key is into the grooves on the metal pipe and
the CPVC coupling adapter. Insert the bolts and hand tighten. Tighten the bolts alternately and equally until the bolt pads
are touching metal-to-metal. In completing a proper joint, the gasket is also slightly compressed, adding to the strength of
the seal from the gasket’s durometer.
5. Inspect the joints before and after pressure testing. Look for gaps between the bolt pads and for housing keys that are
not inside the grooves.
Other Design Criteria
Chemical Compatibility
CPVC domestic water, fire sprinkler, and industrial piping systems have been used successfully for more than 50 years
in new construction, re-pipe and repair. CPVC products are ideally suited for these applications due to their outstanding
corrosion resistance. Occasionally, however, CPVC can be damaged by contact with chemicals found in some
construction products (and site preparations). This may result in damage to property, people, or the BlazeMaster® CPVC
fire sprinkler system. Reasonable care needs to be taken to insure that products coming into contact with CPVC
systems are chemically compatible.
Ampac Safety recommends that chemical compatibility with CPVC be confirmed with the manufacturer of the product in
contact with CPVC piping systems. If chemical compatibility with CPVC is in question, Ampac Safety recommends
isolating the suspect product from contact with CPVC pipe or fittings.
Lubrizol maintains a list of products that have been shown to be UNACCEPTABLE for (unprotected use) contact with
CPVC systems. Chemically incompatible products are added to this list as they are brought to our attention. For the most
current list of chemically incompatible products, contact Lubrizol or refer to the Chemical Compatibility Section at
www.lubrizol.com/BuildingSolutions/BlazeMaster.html. A product's absence from this list does not imply or insure CPVC
chemical compatibility.
The FGG/BM/CZ™ System Compatible program identifies products that have been determined to be compatible with
CPVC compounds supplied by Lubrizol, such as BlazeMaster® CPVC. Products included in this program carry the
FGG/BM/CZ™ System Compatible logo on their label. Additional information on this program can be found on the
internet at www.lubrizol.com/BuildingSolutions/BlazeMaster.html.
ALWAYS CHECK THE PRODUCT MANUFACTURER'S RECOMMENDATION IN THIS REGARD.
A Note on Microbiologically Influenced Corrosion (MIC)
In areas where water supplies are known to have contributed to MIC metallic fire sprinkler system water supplies should
be tested and appropriately treated. This testing and treatment is not required when using BlazeMaster® CPVC
products. BlazeMaster® CPVC is not susceptible to MIC because:
1. CPVC surfaces discourage the adherence of the bacteria associated with MIC. In metallic systems, colonies form
around the bacteria that entrap organic acids against the wall, causing the pitting which is common with MIC.
2. As the bacteria associated with MIC cannot adhere to the inner surface of CPVC, the bacteria will not propagate as
rapidly.
3. The organic acids produced by the MIC bacteria promote the oxidation of metals but do not affect CPVC. In fact, the
compounds that comprise BlazeMaster® pipe and fittings are known to be unaffected in extreme acid environments far
more severe than those environments associated with MIC.
Note: Metal components within non-metallic fire sprinkler systems are not immune to MIC.

Batt Insulation
If batts are to be used for freeze protections, they should be used in accordance with a published guideline or calculations to
indicate the minimum thickness to be used and any other application criteria.
Antifreeze Solutions
Where installations are subject to freezing, the criteria in AS 2118.1 may be consulted. AS 2118.4 recommends the use of
a dry system for freezing conditions which precludes the use of CPVC pipe. If required, utilising CPVC pipe in freezing
conditions will be best undertaken utilising an alternative solution relying on the design criteria in NFPA 13 and further
information available on request
Painting
Painted BlazeMaster® CPVC pipe and fittings have not been evaluated by UL and are outside the scope of the UL and
cUL Listing. Water-based acrylic latex paint is the preferred and recommended paint to use on BlazeMaster® CPVC pipe and
fittings. Oil or solvent-based paints may be chemically incompatible.
Certain types of oil or solvent-based paints may, however, be used provided that it is a light coating that dries quickly. These
paints should not be allowed to puddle or pool on the surface. Application of solvent-based paints must be individually
reviewed as there are certain types of paints and stains that contain drying oils and should not be used at all on CPVC.
BlazeMaster® Pipe & Fitting Installations In Concrete
BlazeMaster® CPVC pipe and fittings are acceptable for use when embedded in concrete. Direct contact with
concrete does not have any adverse effect on BlazeMaster® materials.
The installation of BlazeMaster® CPVC pipe and fittings in concrete has not been evaluated by UL and is not
covered under the scope of the UL Listing. Note that embedding of any type of pipe in concrete is prohibited by AS
2118.1, AS 2118.4 and AS 2118.5. Embedding of pipe and fittings would therefore be subject to an alternative
solution.
Typical recommended installation practices should be followed.
following guidelines.
In addition, particular care must be paid to the
1. As the BlazeMaster® pipe is laid out be certain that it does not come in contact with sharp objects or edges,
such as rocks, metal, or structural members.
2. Although CPVC pipe has some degree of flexibility, in laying out the pipe it is best to use straight runs of pipe. It
is possible for CPVC pipe to be snaked when it is laid out. This can be useful in some installations when an offset
from a straight run can be helpful in avoiding various construction obstacles. Straight runs of pipe will minimise any
stress that is exerted on the pipe. When the pipe is embedded in concrete there is no opportunity to relieve any
stress once the concrete is poured. Therefore, it is important to layout the piping such that the stress is minimised
from the time of installation.
3.
Avoid the contact of BlazeMaster® pipe and fittings with construction materials that are incompatible with
CPVC. Verify the suitability of a particular product for use with CPVC with the manufacturer of the particular
construction material.
BlazeMaster® CPVC pipe and fittings have been successfully installed encased in concrete for many years. Neither
Lubrizol (the manufacturer of BlazeMaster® CPVC material) nor Ampac Safety is aware of any problems that have
been caused by chemical incompatibility between BlazeMaster ® pipe and fittings and concrete or any chemicals
that have been added to concrete. As new construction materials are introduced to the market it is advisable to
contact the manufacturer of the construction material to confirm its chemical compatibility with BlazeMaster®
CPVC.
Page 22
4. Steps must be taken to prevent the wire mesh or reinforcing bars from causing any abrasion damage to the
BlazeMaster® pipe and fittings. This is mostly of concern prior to pouring the concrete. It is not recommended that
BlazeMaster® pipe and fittings be installed in concrete that is to be post tensioned. The post tensioning process can
create excessive forces which can damage the BlazeMaster® pipe.
5. When there are pipe joints that will eventually be covered in concrete, the installation must be pressure tested
prior to pouring the concrete. If there will not be any joints covered by concrete, there is no need to pressure test
the system prior to pouring the concrete.
6.
Prior to the pouring of the concrete, the BlazeMaster® pipe should be intermittently secured to prevent
movement during this process. Nonabrasive, plastic fasteners are good choices for this application.
7. Care should be taken so that the BlazeMaster® pipe and fittings are not damaged by the tools and equipment
used to pour and finish the concrete. BlazeMaster® pipe and fittings should not come in contact with equipment
such as tampers and agitators.
8. As the concrete is poured, assure that the pipe has not moved from its intended position.
9. Thermal expansion and contraction is not an issue for BlazeMaster® pipe and fittings that are embedded in
concrete. Those forces are relieved in a manner that does not affect the pipe or fittings. However, expansion and
contraction must still be incorporated in the design of those sections of pipe that are not embedded in concrete.
Failure to adequately allow for stress at these points may result in damage to the pipe where it enters and exits the
concrete.
10. In order to allow easier access to the sprinkler head adaptor it is recommended that the adapter not be
encased in concrete. Provisions should be made prior to pouring the concrete so that the concrete does not encase
the sprinkler head adapter and the pipe immediately attached to this fitting. Protective coverings may be utilised to
prevent the concrete from surrounding the sprinkler head adapter and the pipe supplying it. This will allow easier
access to the fitting should modifications be required to the system.
Maintenance
Maintenance of a BlazeMaster® fire sprinkler system shall be in accordance with the Standard for Inspection,
Testing and Maintenance of Water Based Extinguishing Systems as defined by AS 1851.
Penetrating Fire Rated Walls and Partitions
Consult relevant building codes before penetrating fire rated walls and partitions,. Several classified through
penetration firestop systems are approved for use with CPVC pipe. Consult Ampac Safety for further information.
Warning: Some firestop sealants or wrap strips contain solvents or plasticizers that may be damaging to CPVC.
Always consult the manufacturer of the firestop material for compatibility with BlazeMaster® CPVC pipe and
fittings. To avoid compatibility issues, reference the Chemical Compatibility and FGG/BM/CZ™ System
Compatible program sections of www.lubrizol.com/BuildingSolutions/BlazeMaster.html for additional
information.
Earthquake Bracing
Since BlazeMaster® CPVC pipe is more ductile than metallic sprinkler pipe, it has a greater capacity to withstand
earthquake damage. In areas subject to earthquakes, BlazeMaster® fire sprinkler systems shall be designed and braced
in accordance with local codes.
BlazeMaster® CPVC fire sprinkler pipe has the flexibility to meet this criteria. The permissible bending deflection values
for BlazeMaster® CPVC pipe can be found in the tables in the Pipe Deflection section of this manual.
When it is required to earthquake brace BlazeMaster® piping, it is important to use fittings, fasteners or clamps
that do not have sharp edges or apply compressive forces sufficient to distort the pipe.
Page 23
Summary
BlazeMaster® pipe and fittings, designed specifically for fire sprinkler systems, provide unique advantages. Long-term
performance of a BlazeMaster® system will be maximised if it is properly installed and maintained in accordance with
applicable Australian Standards.
