Unitherm's Heat Control product line consists of:
Pre-Insulated tubing & pipe to be used for steam supply, gas transport, or liquid
transport. This product allows for fast and easy installation. Also provides personal
protection as a natural benefit.
Pre-Insulated Steam Traced tubing offers predictable, constant thermal characteristics,
fast and easy installation of a light weight and durable product. It is used for small
diameter process lines, analyzer and instrumentation lines, and instrument impulse lines.
Available in light, medium, and heavy steam tracing designs.
Pre-Insulated Electric Traced tubing has all the same features of Steam Traced
product and gives all the same benefits, except it utilizes an electric heater instead of a
steam traced line. It is Factory Mutual approved for use in Class 1 Division 2 Groups B,
C, and D hazardous areas.
Flexible Heated Hoses are widely used in the Industrial and Constant Emissions
Monitoring (CEM) markets.
Industrial uses include Hot Melt Glue application, heated transfer lines used in blow
molding of plastic bottles, extrusion of plastic bags, injection molding of artificial
fishing lures. Other applications are disposable diapers and gel cap medicine.
The Continuous Emissions Monitoring industry depends on Unitherm to provide
multiple heated and unheated tube design combinations that include various gauges and
colors of messenger wires and thermocouple extension wires. We design hoses to
operate at freeze protection temperatures or 625(F) (329(C), manufacture lengths as
short as 2 feet and as long as 200 feet in continuous lengths (longer lengths are
possible), provide electronic controllers to maintain minimum temperature requirements.

Installation Guidelines
NOTE: INSTALLATION SHOULD BE PERFORMED ONLY BY
PERSONNEL PROPERLY TRAINED IN INSTALLATION
PROCEDURES!
Installing Steam Supply and Condensate
Return Lines
Running
Introduction
1) Begin running the pre-insulated lines from the manifold to
the traced piping or other process equipment.
Use of Dekoron/Unitherm’s pre-insulated steam supply and
condensate return lines offer cost saving features in both
installation and energy conservation.
Features
• Long lengths for ease of storage, handling
and installation
• Prefabricated construction for employee
protection and energy efficiency
• Light, durable and easy to handle
• Semi-flexible for ease of handling and support
• Easily installed while maintaining
system integrity
Manifold Systems
Manifold systems are a major part of the efficient, welldesigned steam tracing system. They simplify the design,
engineering, installation and check-out and provide for an
easily maintained system.
Manifolds may be fabricated in many configurations to meet
both space and steam capacity requirements. Examples
shown here illustrated several types of manifold systems that
may be utilized.
2) Lines can be grounded and supported as they leave the
manifold.
3) Long-length coil should be placed at the manifold –
supported on a free-wheeling A frame – and runs then
pulled to the tracer connections. These runs may be
grouped and firmly supported using existing framework
and piping.
4) Horizontal runs should slope back to steam trap for
proper drainage.
5) Multiple groupings must allow space for heat dissipation.
A space of 1 / 2 “ or more between the pre-insulated lines
is recommended. Layered horizontal runs can be made
by providing a wooden or insulating block spacer between
layers at the recommended
support centers.
NOTE: Recommended Installation Temperature for Lead-free
FRPVC is -25F or higher.
Supporting
1) Cable tray may be efficiently used in horizontal support
systems where runs are long enough, space allows, and
support members are distant (such as along pipe alleys).
a) When running pre-insulated steam lines in cable
tray, allow a minimum of 1 / 2” spacing between
lines, and when layered provide an insulated spacer
at the recommended support center. Higher
temperature bundles require greater
spacing. See www.unithermcc.com for more
information.
b) Lines should be secured in the tray every 10 – 15
feet and within 18” of any directional change.
c) DO NOT firmly support within a bend as this will
limit the movement due to thermal expansion.
d) Support clips or clamps should have a wide
bearing surface. Securing hardware SHOULD NOT be
the type that exerts point pressure or can be
over-tightened. Support clamps should be sized one
size less than bundle O.D.
2) Existing structures may be used to simplify the support
requirements and reduce installation costs.
www.unithermcc.com
Installation Guidelines
3) Where an existing structure is not available, individual lines
may be supported in channel or angle and secured with
tie-wrapped fasteners.
Maximum Support Centers
Vertical...................15 ft.
Horizontal.................6 ft.
• DO Slope for condensate 1 / 2 inch (min.) per foot run.
• DO Check to ensure that all electrical connections are
tight and sealed.
• DO Check to ensure that all connection box covers have
gaskets and are fastened tightly.
• DO Secure end kits when using Teflon tube trace products
to reduce strain on the fittings.
DO
• DO Provide long sweeping bends where possible. Support
4 to 6 inches (100 – 150 mm) from start of bend, with
wide bearing supports. Slight wrinkling of the outer jacket DON’T
is normal when the product is bent. Excessive wrinkling or • DO NOT Exceed minimum bend radius.
folding of the jacket indicates that the minimum bend
• DO NOT Exceed recommended support centers
radius has been exceeded.
• DO Seal all exposed insulation with RTV end sealant.
Bundles must be sealed at each end to prevent moisture
and corrosive atmospheres from damaging the tubing and
other components.
• DO Use existing cable trays, columns, beams and other
structures when routing traced bundles.
• DO NOT Over-tighten support clamps – jacket should not
be pinched.
• DO NOT Tie multiple runs together to form one bundle.
Proper spacing (1 / 2” minimum) is
required for heat dissipation.
• DO NOT Severely crimp jacket as this may effect insulations properties.
• DO NOT Remove excessive amounts of jacket and insulation at fittings.
• DO NOT Allow the heating element to be in contact with
the sensor.
• DO NOT Route bundles over furnace vents or other high
heat sources or in traffic areas where they might be damaged by equipment or pedestrians.
• DO Seal fittings and splices with a seal patch.
• DO Remove the jacket and insulation to make sharp, 90º
bends. Then, re-cover with seal patch kit. Use a union
elbow where tight bends are necessary and seal insulation.
• DO Use a mandrel to assure constant radius bends
(where possible).

Steam Traced Tubing
Series 2202/2204
Light Steam Traced Tubing
DEKORON®/Unitherm™ Series 2202/2204 Light Steam Traced
Tubing bundles are designed to protect a process fluid from
freezing at ambient temperatures to -40ºF (-40ºC) using saturated steam. Each bundle consists of:
• Single or multiple, individually insulated metal
or polymer process tubes
• Insulated metal steam tracer tube covered with
a heat reflecting foil
• Impulse lines – D/P cells
*Maximum Temperature Rating( MTR) is the design condition
for which this product is manufactured. Temperatures in
excess of this rating may result in deterioration of the components or changes in the operational characteristics.
• Moisture-resistant, non-wicking, inorganic,
• Seamless, weather-protective, lead free,
low-temperature PVC outer jacket.
Designed for light tracing of process, sampling and impulse
lines, Series 2202/2204 bundles are recommended for use in
situations where heavy tracing will cause high temperature
degradation or boil-off of the process fluids. Highly efficient
and compact, these products are designed to limit the jacket
to a nominal surface temperature of 140ºF (60ºC) or lower, at
80ºF (26ºC) ambient conditions, with tracer conditions at
400ºF (204ºC) 232.6 PSIG saturated steam. Higher temperature designs, for tracing applications up to 1000ºF (538ºC),
are also available. Maximum Temperature Rating = 400ºF.*
2202
The standard jacket is a black, 105ºC, lead-free, LT-FRPVC.
Alternate jacket materials are available including: 125ºC FRTPE amd FR-Urethane.
• Compact Design
• Low heat loss
• Low-maintenance

Purpose
This bulletin provides the Field Engineer and the craft people with information for the proper
installation of Unitherm Electrically Traced products. These recommendations have been proven by
years of actual experience. They are put forth as suggestions and do not preclude the use of other
methods and good field construction practices are discussed in detail with the use of step-by-step
instructions, illustrations, and diagrams. Various charts are included to cover product specifications,
recommended support centers, and minimum bend radii, to guide in all phases of planning and
installation.

Hanging and Support Instructions
Electrical Connection Kits
2.0
Handling and Storage
All Unitherm Traced products are shipped on non-returnable wooden reels, which take minimum
space and provide maximum product protection. The standard reel for analyzer bundles has a 54"
flange, is 36" wide, with a 40" drum, weighing 160 pounds. Other reel sizes may be used,
depending upon coil lengths.
Each length is sealed at the ends to prevent entry of moisture or foreign material. However, if reels
are to be stored out of doors at the jobsite, a weatherproof covering (e.g., polyethylene film, canvas,
etc.) should be used.
3.0
Planning and Preparation
The methods recommended for installing Unitherm Traced products are based upon accepted
practices presently used by Instrument Engineers, Electricians and Pipe Fitters. Planning and
preparation are essential to proper installation.
Initial planning and system layout is recommended to take total advantage of the installation cost
savings. Preliminary planning should encompass such things as: determination of run lengths,
position and angle of probe connection, accessible routing of the Analyzer line, existing support
structures and their location, entry into the analyzer house and the possibility of external tracing
requirements beyond the bundle. It is important to review the section on hanging and supports
while planning the run to make the best use of existing supports.
Check with DEKORON/UNITHERM Customer Service for information on the size, weight, support
distance, and minimum bend radius of the bundle being installed.

Length Determination
Bundle length is determined by the routing distance between sample point and instrument.
However, some allowance for extra length should be made. Minimum additional length requirement
for each connection point, such as splice, termination and input power kit, should be 12 inches.
Allowances must also be made for routing inside probe enclosures and the analyzer housing.
5.0
Routing
The initial consideration in establishing the best route is to install instruments and adjacent supports
which will allow the traced line to run straight for 12" to 18" before being connected to any
instruments, sample points, orifice plates, etc. This will simplify the job of connecting after the
bundle is secured.
Wide bearing
clamps
TYPICAL
BUNDLE
Existing Pipe Run
FIG 1
Routing should be chosen to take advantage of existing cable trays, beams, columns, etc. Provide
long radius sweeping bends whenever possible. Long radius bends allow the bundle to work at its
maximum efficiency and also provide a place where the bundle can expand and contract due to
ambient and tube temperature changes. Tighter bends can be made, as explained below. Take
care to insure that all bends are greater than the minimum bend radius. Support the bundle from 6
to 10 inches either side of the bend with wide bearing clamps (see fig. 1). The routing should not
position the product in an area where the ambient will reach above 120qF (49qC), such as near a
boiler, reactor, heat exchanger, or against a hot chimney wall; unless the bundle is designed
specifically to handle high ambient temperatures. If the bundle is routed within an enclosed cable
tray or conduit, this maximum temperature may be reduced. Contact Unitherm Customer Service
for information on the limitations of your bundle.
Horizontal runs should be sloped to assist drainage of any condensate or particulate matter that
may collect in the tube. Unitherm suggests a slope of 3/4 inch per foot of horizontal run. In systems
where there is high gas velocity, this slope could be decreased.
Multiple bundle routing, where more than one bundle is run in parallel, should allow at least 1" space
between bundles. Bundles may be stacked if insulating spacers, no less than 1" thick, are used.
6.0
Methods of Installation
The Unitherm products range from semi-rigid Traced bundles to extremely flexible Heated Hoses.
These products cannot be treated like power cables. The maximum pulling tension on most
Unitherm analyzer bundles is less than 50 pounds, so they cannot be simply attached to a draw
cable and pulled into place.
Installation generally begins at the probe end. If the probe is elevated, position the reel at the base
of the stack, if possible directly below the line where the bundle will be secured. A draw cable can
be fitted with split pulling grips (see Figs 2 and 3). These grips are attached to the bundle at
intervals of 35 feet maximum. The cable and bundle are then pulled up to the level of the probe.

Draw cable
Pulling grip, spaced at
intervals no greater than
35 feet. Spacing is closer for
bundles with multiple heated tubes
or multiple messenger wires.
Analyzer or Probe Support Bundle
Raising bundle up stack
(FIG 2)
NOTE: the cable grip is not a recommended method for securing the bundle to the stack.
Other methods must be employed. If the vertical run is offset around the stack from the probe
location, the installer should pull sufficient bundle up the stack to make the offset. The bundle is
secured on the vertical run before routing the bundle around the stack. Do not attach pulling blocks
at the top of the vertical run and pull the bundle from the probe location. The force applied at the
pulling block is sufficient to damage the internal components even though there may be no apparent
damage to the jacket.
Route the bundle from the vertical run to the probe. Again, allow extra bundle for routing into and
connecting to the probe.
PULLING
GRIP
Plain Grips: Kellems K100P orReliable 824
Split Grips: Kellems UB125-A or Reliable 1863
Begin securing the bundle within 18 inches of the probe,
using clamps and installation accessories detailed the
following sections. Never use wire or cable ties to secure
Unitherm Analyzer bundles. Follow the bundle back from
the probe, securing the bundle at the recommended
support locations. Unitherm bundles are generally
supported every 6 feet on a horizontal run and every 15
feet on a vertical run.
(FIG 3)
Once the bundle is secured at the base of the stack, it can then be routed along exiting structures or
in cable trays to the analyzer house. At this point, the draw cable and cable grips can be removed
and used on another bundle. Again, the bundle should be laid in, not pulled.
On reaching the analyzer house, sufficient bundle should be pulled off the reel to route into the
analyzer house and to the analyzer cabinet.
Contact Unitherm Customer Service for
recommendations on bulkhead fittings and entry seals for this application.
7.0
Methods of Bending
Bending the DEKORON/UNITHERM traced products can be accomplished by various means,
depending upon the product type and size. In any case, no bend should exceed the minimum bend
radius. Exceeding the bend radius can result in damage to the bundle jacket, core tubes, and
heater (see Figure 4). Since most analyzer bundles are constructed using Fluoropolymer tubing,
they can be bent by hand. If the metal tubes or a number of messenger wires in the core, other
methods may be needed. A thin wall conduit or MCM cable bender can be used with the smaller
O.D. tube bundles. Other types of benders can also be used for all products if care is taken to
prevent flattening of the tube(s), damaging, or misplacing the heating element. (A small amount of
wrinkling in the jacket is normal and does not indicate bundle failure or loss of bundle properties.
UNITHERM ™
Page 4

OK
A stationary mandrel may also be used for bending.
The mandrel, such as a cable reel flange, should have a
diameter of twice the minimum bend radius of the
particular product. If the mandrel is smaller than twice
the minimum bend radius, the complete bend cannot be
made in one operation. Several large curvature bends
must be made throughout the entire bend area so as
not to exceed the minimum bend radius. The installer
should also use this procedure when hand bending.
NO
(FIG 4)
8.0
Uncoiling Methods
A freewheeling payoff stand should always be used when uncoiling analyzer bundles. Back tension
should only be enough to keep the reel from overrunning the pull. Tension should always be
minimal.
9.0
Hanging and Supports
Unitherm traced products should be supported securely according to the support center dimensions
shown in the Unitherm catalog. In addition to these dimensions, the product should be securely
supported within 18 to 24 inches of any connection kit. Suggested support methods are listed
below.
9.1
Angle Iron
Angle Iron, sized to the closest 1/2" to the nominal bundle O.D., can be used effectively to support
long vertical or horizontal single bundle runs. The Unitherm traced product is secured to the angle
iron with either plastic or metal strap ties (Figure 6). As always, strap ties should have wide bearing
area and should not be so tight that they deform the jacket of the analyzer bundle more than 1/8
inch. Horizontal runs should have the angle iron over the Unitherm traced product to prevent
containment of water, ice and snow.

Channel Iron
Channel Iron can be used in the same manner as angle iron, but can accept multiple bundles if
sizing is made to allow bundle separation. Strap ties may also be used here.
9.3
Cable Tray
Standard industrial grade cable trays are best suited for multiple product runs. The product should
be anchored to the tray to maintain clearance between the bundles. Securing each bundle to the
tray within 6" to 10" of either side of a bend is recommended. The minimum spacing rule of 1 inch
should apply on straight runs and bends (see Figure 7). Cable tray bends should be sized to the
next standard size above the minimum bending radius of the bundle.
9.4
Pipe or Tube Supports
Unitherm recommends individual supporting hardware that has large supporting surface areas and
cannot be over tightened to the point where the support can crush the product and damage the core
tube or heating element (see Figure 8).

Strut clamps are sized according to the bundle diameter and the location of the clamp. Clamps
used on horizontal runs are sized to the nearest standard size greater than the bundle diameter.
This allows the bundle to expand and contract through the clamp. Clamps used on vertical runs are
sized to the nearest standard size less than the bundle diameter. This provides a secure anchor for
the vertical run. Smooth radius bends at each end of the vertical run are recommended.

Terminal Expansion
The construction of the Unitherm traced products inherently allow for movement caused by thermal
expansion and contraction. The minimum bend radius is large enough to absorb tube movement
due to expansion. If there are no bends in a run using a single metal process tube product, some
method, such as an expansion loop, should be used to take up the movement.

Electrical Connections
The following section deals with terminating and connecting Unitherm heated analyzer bundles to
electrical power. If the bundle is factory sealed and terminated (common with Unitherm Heated
Hose products), follow the instructions on the label attached to the power lead wires. The power
lead wires are the two white and one green wire exiting from the power sleeve at the power end of
the bundle.

CPD Heater
The Constant Power Density (CPD) heating element used in Unitherm 2252 and 2262 Series
bundles is constructed of two parallel, stranded, nickel plated copper bus wires with spiral wound
zones of high resistance heating wire. Alternating bus contact at fixed intervals form a chain of
parallel zones equal resistance producing constant power output in each zone. These circuits, or
zones, can be found by feeling for a small lump on the edge of the heater. (see Figure 12)
Since the heating zone must be connected to both bus wires to operate, the wire past the last bus
connection to the end of the heater will be cold. Care must be taken or the first one to two feet of
the bundle will have no heat.

Installation without Connection Kits
Use of the DEKORON/UNITHERM 1548-12000 or 1548-1200J connection kit is a convenient way to
insure a safe power connection and termination in all applications, and is required if the installer is
terminating in an area classified as hazardous under the National Electric Code. If the installation
does not require the use of these connection kits, certain procedures must be followed:
1
The heating wires must be connected to the cold lead wire or spliced together with an approved
crimp connector, which will withstand the temperatures generated.
2
The connections should be insulated with high temperature electrical insulating tape.
3
The ends of the product should be sealed to prevent the entry of water. Sealing can be done by
using a sealing grommet type bulkhead connector for entrance into an instrument enclosure,
analyzer cabinet or a power supply cabinet. A high temperature sealant or cement, such as Part
No. 1535-02080 End Sealant can be used to encapsulate the end. Whichever method is used, the
National Electrical Code and all local codes must be followed.
Allow a minimum braid length of 6" for input power and termination kits and 12" for input
power splice and splice kits.

Accessory Installation Notes
Detailed and comprehensive installation instructions for all accessory items are provided with the
kits.
Thermostat (1660-13A12 & 1660-18912)
The thermostat can be used in conjunction with a connection kit or in line with the power supply. If
the thermostat is to be kit mounted, the kit must be placed that so the thermostat will sense the true
ambient or tube temperature and not the temperature generated by a boiler, reactor, heat
exchanger, or other heat source.

Final Check
1
Check that all hangers and supports are secure to bundle, but not overly tight.
2
Check for extreme jacket kinking and for bends less than the minimum radius.
3
Check that all electrical connections are tight and properly insulated.
10
11
4
Check that heating element is not in contact with the temperature sensor.
5
Check that all connection kit covers have gaskets and are fastened tightly.
6
Check that all connections and components meet NEC and all Local Codes.
In addition to the above tests, the installer may elect to run a series of pre-commissioning tests.
These tests check the electrical and pneumatic integrity of the analyzer bundle. Unitherm has
developed a series of pressure / vacuum / electrical tests for this purpose.
18.0
Pre-Commissioning Test Program for
DEKORON/UNITHERM Analyzer Bundles
18.1
Scope
This procedure covers pressure, vacuum tests run on sample line tubing, and electrical tests run on
electric heating elements prior to commissioning Unitherm electrically heated analyzer bundles.
18.2
Equipment required
1
Pressure gauge capable of reading 0-30 psig
2
Vacuum pump with gauge and flow meter (typically analyzer sample pump)
3
Portable volt-ohm meter
4
Portable megger
18.3
18.3.1
Procedure
Pressure Test
The purpose of the pressure test is to determine if there are any leaks or pinholes in the sample
tubing.
1
Cap the tubing at the probe end of the bundle.
2
Pressurize the sample tube to 30psig and close off the supply.
3
Watch the pressure gauge for any drop. Typically, the tube pressure could drop up to 5 psig over 10
minutes due to cooling of the air; any further drop could indicate a leak.
4
If the gauge pressure drops more than 5 psig in 10 minutes, check all connections to insure that
there are no leaks at the connection points, and re-pressurize the tube.
5
If the gauge pressure again drops, and there are no detectable leaks at the fittings, check for
mechanical damage at the ends of the bundle, where the tubing is unprotected.
6
Continued pressure drop with no observable leaks indicates a pinhole within the bundle.
18.3.2
Vacuum Test
The purpose of the vacuum test is to determine if the tubing is plugged or kinked within the bundle.
1
Attach the probe end of the bundle to a filter to prevent dust and dirt from being drawn into the
sample tube.
2
Attach the analyzer end to the analyzer pump or auxiliary vacuum pump.
3
Energize the pump and record the airflow rate and vacuum level.
4
The values recorded above must be within the analyzer manufacturer's specification to insure that
the proper sample volume is pulled into the analyzer.
5
A high vacuum level with very little flow could indicate a kink or plug in the sample line.
6
7
18.3.3
1
UNITHERM ™
Page 12
A moderate to high vacuum level with normal flow could indicate the sample line is undersized for
the flow rate required and the length of the sample line.
A moderate to low vacuum level with normal flow indicates there are no plugs or kinks in the sample
tubing.
Electrical Test
The purposes of the electrical tests are to insure that the heater is continuous and has no faults in
its electrical insulation.
11
12
2
Read the resistance across these bus wires from the probe end of the bundle. Typical bus wire
resistance should be less than 10 ohms. A high bus wire resistance indicates a broken lead wire
within the bundle.
3
Tie the two heater bus wires together at the probe end of the bundle and electrically insulate them to
insure they do not short out against the braid or any ground point adjacent to the heater cable.
Note, the bus wires are tied together only for this test. They must be separated for final installation
and termination.
4
Attach a portable megger at the analyzer end of the bundle
The positive lead of the megger should be connected to the two heater bus wires that were twisted
together in the earlier test. The negative lead of the megger should be connected to the heater
braid.
5
Megger the heater at 500 VDC. The megger reading should be greater than 10Meg Ohm.
6
If the megger reading is less than 10Meg Ohm, check for contact between the braid and the heater
bus wires at both ends of the bundle.
18.3.4
Test Complete
On completion of the above tests, the sample line is ready for final installation and commissioning.
Install termination and input power kits to bundle per the instructions supplied with the kits.
