New commercial water heating systems:
A
sk Chuck Appleby, president of Old Lyme, Conn.-based
Appleby Plumbing Co. if he recalls an emergency job. One he
quickly remembers began with an urgent, Christmas day plea
from a restaurateur who needed half a million Btu of water
heating at the height of his business season (see sidebar
story).
Appleby was there on site within 30 minutes. While studying
the restaurant’s need for hot water, he discovered that the old,
leaking beast was sized for peak load, making it at least 20 percent too large 90 percent of the time. The big, atmospheric system could be replaced by a 400 mBh condensing unit that
would be smaller in size, a whole lot less expensive to operate,
and, if need be, could be coupled with a smaller indirect water
heater to meet peak loads.
The new water heater, which offered a much greater recovery rate, was also a lot less burdensome to install than the old
one, not requiring the large, ducted air vent. The new system,
a condensing water heater, would require only a 3-inch PVC air
intake and a 3-inch PVC flue gas discharge. “A piece of cake,”
said Appleby while marveling at the extraordinary efforts (and
expense) taken to install the intricate air passageway for the
unit that would soon be replaced.
“The new unit’s sealed combustion is a huge benefit for
restaurant jobs, eliminating all concern about one of the tricki8

est challenges with commercial facilities where food is prepared,” added Appleby. “Large ventilation hoods are notoriously adept at stealing combustion air from atmospherically fired
systems. Those days—thanks to new, sealed combustion technology—may soon be gone.”
Appleby’s experience with the system he replaced is illustrative of the way water heating technology has changed in just
the past couple of years. Not long ago, contractors, engineers,
and building owners were routinely challenged by an inability to
easily place and locate commercial water heaters. The limitations of atmospherically vented systems, facility design, aesthetics, and close proximity to other buildings all factored in.
Today it’s not uncommon for facility managers, late in the
game, to express an aversion to visible venting, based purely
on aesthetic reasons. This is especially true in historic districts.
Fortunately, many of the obstacles to easy placement of
water heaters—at least those tied to building design and construction—are overcome with the emergence of new water
heater systems, making it much easier to achieve manufacturer-specified combustion air or venting runs.
The arsenal of commercial water heater products and associated technology has grown considerably, availing a wide
range of fuel, venting, and combustion air options. There are
also many new application-friendly components and techniques to enable trouble-free specification and installation,
although, with the new green systems, a few new needs
emerge.
Higher efficiency, condensing systems are great for endusers in terms of energy consumed, chiefly because they harvest heat from waste condensate. The energy advantage requires modest design and installation changes to meet the
need for condensate treatment and drainage. This may translate to an inability to use existing venting if the original water
heater was atmospherically vented, and the availability of electricity. Some systems require hard-wiring; other commercial
systems need only a simple wall plug-in.
Condensate drainage is a likely necessity. Often, fluids to
be drained are too acidic for metal drain lines. Routing the con(continued on page 10)

historic inn needed a substantial
overhaul brought on by the sudden
death of an eight-year-old, half-millionBtu commercial water heater, the only
source of domestic hot water for the inn’s
award-winning kitchen.
“Of course, the old inn wasn’t built to
accommodate modern mechanical systems,” said Appleby. “He specified a new,
400 mBh, LP-fired, high-efficiency eF
water heater by Bradford White to replace
the quickly deteriorating system installed
by another firm.
The water heater they replaced had required a 12-inch stainless steel draft hood
and chimney. “Too bad they had to spend
that kind of money on a water heater with
such a short life span,” said Appleby. “The
new system we installed requires only a
simple, four-inch PVC stack and, at 98
percent efficiency, would cost them a
whole lot less to operate. The key advantage was the new, condensing unit’s
super-high recovery rate. Because we
could heat so much more water, we were
able to size it at 100,000 fewer Btu, a
move that also had a huge impact in their
fuel consumption.”
Another attribute is that there are no
stack losses because the new system is
equipped with sealed combustion and
uses both PVC exhaust and combustion air
lines. The water heater also offered several venting options, electronic controls, four
protective magnesium anode rods, a sediment reduction system and factoryinstalled dielectric fittings.
Considering the sad waste of resources
on the stainless steel stack, which Appleby
left in place, he devised a plan that gave it
new purpose. “We used it as an intake air
ventilation duct to cool the restaurant’s
large refrigeration equipment,” he said.
“They had a growing problem there because the equipment had been running
hot, and this was consuming electricity
[highest, by far, of all energy sources in the
state] at an alarming rate. Typically, the air
around the refrigeration systems was
120°F to 130°F year round. Using the 12-
inch duct to bring fresh air in, we were
able to get those temperatures down substantially.”
“The biggest benefit of all was in the
energy savings,” concluded Appleby. “Today, no one can responsibly afford to
waste energy.”

densate through a simple, lime-bed acid neutralizer may solve
the problem easily. Better yet: CPVC or PVC drain lines can
handle the acidity. Condensate typically has a pH of 4.0, about
that of Coca-Cola—just enough to attack any metal it connects
with. Over time, the cumulative effect of exposure to acidic
runoff threatens the integrity of the drain lines.
Venting. If new, high-efficiency water heaters are planned
as a retrofit, existing, single-wall B-vent must be replaced in
favor of PVC, CPVC, or ABS plastic. The majority of venting
lines are 3 or 4 inches in diameter, precisely matched to the
design requirements of new blower motor assemblies that discharge from the top of water heaters.
Plastic vent materials are inexpensive and easy to work
with, and yet present no compromise in safety or performance. Some new water heater systems have the ability to vent
through the roof and pull air in for combustion through the
wall; this is a big advantage. The need to improve flexibility of
installation and placement has driven the development of
power, power-direct-vent, through-roof, and sidewall venting
options.
10
JANUARY-FEBRUARY 2014
Finally, if the application offers abundant atmospheric combustion air, some water heater models require only one pipe for
venting.
Multistory and high-rise installations challenge traditional venting. High-efficiency water heaters often can accommodate long venting runs. Often, there’s no need to run vertical venting all the way to the roof, requiring a roof penetration.
Many systems are now just as well served with sidewall venting.
New codes are forcing all of us to be attentive to a broad
range of emerging requirements. National, state, and local
codes are changing in the wake of the green movement’s more
stringent environmental policies and initiatives. Among the
applicable national codes is the need for water heater systems
over 199,999 mBh to be ASME-certified.
Historic settings are commonly guarded by restrictions
that regulate the presence and appearance of modern building
systems and attachments (i.e., wire, regulators, transformers,
and venting). In fact, the presence of old and unsightly or loud
venting systems has actually encouraged the replacement of
aging atmospheric water heaters. !

Q
HOT WATER
by Rich Grimes
Please explain a "cold water sandwich" and what causes
this to happen.
A cold water sandwich can occur on tankless water heaters
when the system keeps drawing hot water, but the heater
cycles off and then back on again, after a time delay. This does
not occur with every tankless model, but it is relative to water
pressure change, typically triggered by a single-handle faucet
or shower valve.
What are the requirements for ASME construction in
the State of Florida?
The ASME boiler code calls for ASME construction of water
heaters, boilers, storage tanks, and expansion tanks if one or
more of the following conditions apply:
1) Any unit that is rated at 400,000 Btu or more (gas fired)
2) Any unit that is rated at 120 gallons or more
3) Any unit that is rated over 58 kW Input (electric fired)
Some manufacturers sense only flow rate and do not use
any time delay. These heaters are sensing a minimum flow
rate (typically .5 gpm to activate) and will shut the burner down
if the flow rate falls below .4 gpm. Once a flow rate of .5 gpm
is reestablished, the heater will immediately restart. Heaters
that sense only flow rate do not produce cold water sandwiches.
Most states use 200,000 Btu as their threshold for ASME, but
Florida is higher at 400,000 Btu. You get an understanding why
there are many units rated at 199,999 or 399,999 Btu or 119
gallons or 54 kW maximum.
The heaters that tend to experience cold water sandwiches
sense flow, but they also sense pressure. When a single-handle faucet is adjusted from full hot and then back to center
(mixed hot and cold), the heater senses the pressure drop and
can cut the burner out. Before the heater will restart, there is a
delay of 15 to 25 seconds before the burner fires. The result is
someone taking a shower with steady hot water flowing. If they
make enough of an adjustment on the shower valve, the burner cuts off and restarts in approximately 15 seconds. So what
happens is steady hot water is followed by a 15-second slug of
cold water and then followed by hot water again. It will get your
attention if you experience it!
In summary, flow-only sensitive heaters do not have any
delays in re-ignition and do not create cold water sandwich
effects. Heaters that are flow and pressure sensitive can create
a cold water sandwich in certain conditions, but not always. A
two-handle faucet does not mix within a single cartridge like a
pressure-balancing valve and therefore has zero effect on a
heater that is flow and pressure sensitive.

I am confused by inspectors who call for conformance
with the Florida boiler dode when my heater is rated at
300,000 Btu with 65 gallons of storage. Doesn't my heater
fall below the ASME requirements of the State of Florida?
Your heater does fall below the ASME requirements, but the
inspector is referring to the boiler room itself, not the water
heater. The heater does not have to be ASME constructed.
However, the Florida boiler code calls for a two-hour fire-rated
mechanical room with sealed, fire-stopped penetrations on
units of 250,000 Btu or more. It can be tricky to figure out
sometimes, but it is always best to ask for code interpretation
from your inspector prior to final installation.
I have a high-efficiency heater that vents with plastic
piping due to its low exhaust temperature. My installation
requires the vent piping to run through a return air
plenum. Can I use plastic piping such as PVC or CPVC?
No, not in this application. Many high-efficiency, gas-fired
units can be vented with a sealed plastic vent system. Most
manufacturers specify either PVC, CPVC or ABS as an approved vent material.
(continued on page 14)
Download a description of diaphragm switches and how they operate from:
http://www.statewaterheaters.com/bulletin/TB-A023-06.pdf
(continued from page 12)
Any plastic piping that runs through return air plenums must
be water-filled or specifically rated for use in return air plenums.
In these instances, it is recommended to use a metallic vent
material such as AL29-4C stainless steel in plenum areas. It is
approved as a sealed Category IV vent system and can transition to and from plastic piping. Another alternative is to use a
metallic sleeve, but that can be cost prohibitive and require larger penetrations, firestopping, etc.
Many heater controls, like flow switches and pressure
switches, have multiple electrical contacts. Please explain
the COMMON, NO and NC contacts on these controls.
An internal switch will turn the control on and off based on
flow, pressure, temperature, etc. A switch has a normal position
of either open or closed. When activated, the switch will perform its specific duty to open or close a circuit.
• The COMMON contact is where incoming power enters the
device and is connected to this contact.
• The NC contact is the normally closed contact. It has power
already from the COMMON, but will lose power once the
switch is made.
• The NO contact is the normally open contact. It is an open circuit that receives power once the switch is made.
We will use a flow switch as an example. The flow switch is
a normally open device that closes (switches) upon flow. When
flow reaches a set, minimum flow rate, the power is switched
from the NC contact to the NO contact. So, if wired to the NC
contact, the power is lost upon switch activation. If wired to the
NO contact, power is gained upon switch activation.
A pressure switch may be a normally closed switch or a normally open switch depending on its service. An air-intake
switch is likely to be an NC device allowing power across its circuit, but if the intake gets closed off, the switch will open and
not allow power to pass through. A fan prover switch is likely an
NO device that completes its circuit once the fan has reached
a certain speed or CFM, proving proper combustion fan operation.

http://www.statewaterheaters.com/bulletin/TB-A023-06.pdf.
Why are there multiple high limits and other additional
controls on many heaters and boilers?
Depending on its Btu rating, certain controls are required for
safety. As a unit exceeds the ASME requirement, more controls
are required to meet the ASME standard. For instance, in Florida HLW-stamped boilers are required to have a low water cutoff device (LWCO) and manual reset high limit (MRHL). Hstamped boilers may require additional high and low gas pressure switches. Each state’s boiler inspectors have different requirements to meet their code. Some will require a float-type
LWCO where others will accept a probe-type. A flow switch is
an acceptable form of a LWCO on a circulating boiler/water
heater in Florida.
There are also special insurance requirements like FM (factory mutual) and IRI (individual risk insurers) that have additional controls they will require. Most insurers accept manufacturer’s standard controls on units under 400,000 Btu with additional controls added on larger models. Depending on a unit’s
approval by CSA, UL, ETL, etc., they will dictate the standard
controls. Controls requirements increase with higher Btu inputs, as set forth by the approving agency.
It is very common to see a couple of high limit controls. One
is typically auto-reset and another is manual reset. These controls are wired in series with the operating thermostat. The high
limit controls are designed to prevent over-temperature by
shutting off the boiler. The auto reset control will reset itself
once the temperature has been lowered to a safe condition.
The manual reset is set a little higher than the auto reset and
has the same function. However, if the manual reset is tripped
on temperature, it requires someone to physically reset it. !

his article was prompted by my wife and me watching a
great movie: Saving Mr. Banks, starring Tom Hanks, Collin
Ferrell, and Emma Thompson. Lots of others in the cast, but
these are the main players. It is the story about how Walt
Disney got the film rights to Mary Poppins from the author of
the book, who lived in England. He pursued her for 20 years!
Yep, 20. Not an exaggeration. She was certain he just wanted
to improve his already profit-filled empire, just print some more
dollar bills to add to the mouse kingdom. But Emma stays in
England, not even coming over to discuss it.
What changes her mind is her agent; he lets her know she is
out of money. So, to maintain her home and provide some
funds to live on, she agrees to go to LA to discuss the script for
the movie. She has been told she has absolute control, and
plays it like she has absolute control. She was adamant that
there be no animation, no cartoon characters in her movie. In
fact, she wanted no red colors to be used. She is a woman who
is set in her ways, not to be confused by the laws of physics or
what makes sense.
The movie is not a Disney movie, it is a grown-up movie.
Your 10-year-old would be bored to death. It is told using a
flashback system, going back to Australia when Emma was a
small girl and Collin Ferrell, as her alcoholic father, is a bank
manager. We see his gradual descent into alcoholism, and the
effect it has on the family. Some of those effects are played out
when Disney tries to put the movie together. Of course, we see
this via the flashback; Disney and his team do not. They just
see a woman who is hard to deal with, uncompromising, unwilling to give in on any little item.
Remember I told you, Disney had spent 20 years chasing
her, and now she is on his court, and still it seems like it is going
to unravel. In fact, near the movie’s end, Emma finds out they
are going to have dancing penguins. She is amazed that they
would go to the trouble to train penguins to dance. One of the
producers finally admits, they are going to use animation! She
leaves town, will not sign off on the movie rights, all is lost. Or
so it would seem.
Walt gets on an airplane and flies 11 hours the very next day
to meet at her home, no appointment, just a big surprise. He
confronts her with the idea that the problems she has with the
movie are actually problems with her relationship with her pop,
which have spilled over into her adult life, some 50 years later.

So, he sits there, does an outstanding job analyzing her
responses, and asks again for the right to produce the movie,
complete with dancing penguins. It is amazing.
Here is my application. I realize 20 years is not a realistic
time to follow up in our industry. But how about three years? I
talk to too many sales reps who don’t follow up the next year. I
have seen studies that tell me 70 precent of sales are sold after
the customer has been asked five times. Five! The second concept is that you are never done selling. Walt realized when
Emma hit his town; it was not a done deal. He never gave up!
He went to extreme lengths to put the package together, flying
half way across the globe. Lastly, ask more questions. Walt did
his homework, found out she had changed her name, and why
and where the pain was coming from. Only after doing all that,
he could did he get the signature.
So my question to you is: What are you going to do differently this year? I just had a conversation with Eric Kjelshus, talking about his goals for this year. He is looking to grow sales 25
percent; not a small number. He asked me what would be the
obstacles he may find on that path to profits. I told him that I
see three opportunities as I travel across the nation: (1) Not
enough leads; (2) close ratio is too low; (3) gross margin is too
low, not enough profits in the job.
Those are my three opportunities that are almost always
present. To hear how to solve them, send $20 cash …
OK, just tune in next month, we will work on this and a bunch
more. Don’t send any money! Thanks for listening, we’ll talk
later. !
Oh, and for those who knew, I did have surgery for my rotator
cuff. It was tough to bounce back and have this sling that holds my
arm out at an angle. And it will stay on for six weeks. So hard to
sleep that ended up sleeping on the sofa or the recliner. When I
went into the hospital, I gave out copies of my book and personal
thought-collecting devices—did not want to be another guy in room
315—wanted them to think of me as me! I got two calls and a card
in the mail after the surgery, with their wishes for a speedy recovery. It was an incredible experience. The surgeon told my wife after
the surgery, “I would have never attempted this repair on a tear that
bad, usually we just do a shoulder replacement. But your husband’s faith and courage encouraged me to try to repair the tear,
which was successful.” I believe we can influence the outcome of
even something like surgery by getting those emotional connections. Works for me!

rinder technology
is advancing, and
Liberty Pumps is
at the forefront of
evolving sewage pump
performance. The new
ProVore® grinder from Liberty
Pumps is designed for use
in residential applications
where the addition of a
bathroom or other fixtures
below sewer lines requires
pumping. Traditionally, solidshandling sewage pumps in
the 4/10 h.p. to 1/2 h.p. range,
have been used for these
residential applications. The
solids-handling sewage pump
design passes waste and
solids through the pump in
full form without shredding or
grinding. With lower pumping
heads typically being only
8 to 10 feet (the height of a
residential basement), this
technology, for years, has
provided a reliable, costeffective means for adding
a bathroom or other fixtures
below gravity sewer lines;
however, while providing
an effective solution, the
solids-handling pumps are
susceptible to jamming on
unwanted debris—such as
feminine products, rags or
other difficult solids that may
get flushed into the system.
This is where the new
ProVore® comes in. It
18
JANUARY-FEBRUARY 2014
features Liberty’s patented
V-Slice® cutter technology
utilized in its popular
Omnivore® series of 2 h.p.
grinder pumps. This proven
cutter design easily shreds
solids such as feminine
products, rags, and other
unwanted debris. The
new ProVore® brings this
advanced technology down
to a more cost-effective
residential level. Powered
by a 1 h.p. motor, this smaller
grinder is designed to operate
on a standard 115- or 230-volt
circuit—requiring only a 20amp breaker. No special
wiring, as is necessary with
larger horsepower grinder
pumps, is needed.
The pump comes with a
2" vertical-style discharge
(common on solids-handling
pumps) and a standard leg
pattern matching Liberty’s
LE-Series. This allows for
an easy retrofit into already
existing systems. Engineered
with flow rates to 46 gpm, the
ProVore® provides adequate
scouring in 2" discharge lines
with lower pumping heads
commonly found in residential
basement installations.
Compact, factory-assembled systems are available
in both simplex and duplex
versions. The ProVore®380
uses Liberty’s very popular
PRO380 basin. This system
features Liberty’s QuickTree®
technology for easy field
service of the floats without
removing the cover or
disconnecting the plumbing.
A quick-removal access cover
and heavy-duty, integrally
molded gaskets are also
features found on this system.
In addition, Liberty has
just launched the new
ProVore®680—a compact
duplex version of the 380.
Standing only 24" tall, this
small profile duplex system
utilizes two ProVore® pumps
for uninterrupted service. An
advanced pump controller is
included with the system to
alternate pump operation
and provide an alarm to the
homeowner in the event of
a failure.
Whether it’s a traditional
solids-handling pump or a
newer-style grinder, Liberty’s
broad offering of products
can satisfy a variety of
pump applications; and
with its aggressive product
development strategy, you
can be assured Liberty will
continue to meet the needs
of today’s rapidly evolving

KOHLER OFFERS INNOVATIVE
TOILET NIGHTLIGHTS
Lighting in the home has moved from simply functional
overhead fixtures to uniquely designed lamps, above and
below cabinet lighting, motion-sensored and timed devices,
even in-floor lighting. Every space in the home has its own
type of secondary light source, and now, with the launch of
the Kohler Nightlight toilet seat, so does the toilet.
“Typically, overhead lights are bright because daytime
tasks call for well-lit spaces. But accessing the bathroom at
night is a different story,” says Jerry Bougher, marketing manager for Kohler toilet seats. “One of the fastest ways to ruin
your chances of getting back to sleep easily is to turn on a
harsh, bright, overhead light in the bathroom. The nightlight
toilet seat offers a soft, non-disruptive alternative.”
The new nightlight seat features a lighted hinge, illuminating the toilet space sufficiently to allow homeowners to leave
the overhead lights off while using the bathroom at night, creating a soft ambiance in comparison to overhead lights. The
nightlight casts enough light to allow homeowners easy use
of the bathroom space. Additionally, the nightlight seat runs
on a seven-hour timer, allowing the light to be on during the
night and off during the day when it is not needed.
The nightlight feature is offered on the popular Kohler
Cachet and Reveal seat models, in both elongated and round

Bosch Group, has presented grants from the Bosch Community Fund (BCF) totaling $50,000 to three local organizations that support children
as they learn more about science, technology, engineering,
and math (STEM-related) subjects. The recipients, selected
by an eight-member team of Bosch Thermotechnology associates, are:
• The Boys and Girls Club of Broward County, which gives
children hands-on experience in robotics through its
Robotics Exploratory Program with $19,400 from the Bosch
Community Fund.
• A grant of $15,000 is going to the Florida Atlantic University
College of Engineering and Computer Science’s Engineering Scholars Program to provide up to 150 high school students with classes in engineering and computer science.
• The Miami Dade College North Campus will expand its robotics summer camp with a $15,600 BCF grant.
“Bosch is very excited to partner with the Boys and Girls
Club of Broward County, Florida Atlantic University, and
Miami-Dade College North Campus because they are taking
active steps in helping young people understand that science,
technology, engineering, and math can not only be fun topics
to learn, they can lead to rewarding careers with good-paying
salaries,” said Jerry Smith, vice president of manufacturing at
Bosch’s FHP Manufacturing plant.

DYNAMIC SYSTEMS
ADDS RENTAL FEATURES
TO CHECKMATE
SOFTWARE
Dynamic Systems, Inc., a leader in
mobile data collection applications, has
announced the addition of a rental
option for the Checkmate Tool and
Equipment Software offering.
CheckMate software increases productivity and saves
money by reducing the time it takes to locate equipment and
by ensuring that items will not be lost or left behind. Based on
fast, accurate barcode technology, CheckMate records where
the item is, who has it, and when it is due back. The software
tracks A, B, and C Class items and includes a maintenance
module that records repairs, schedules regular periodic maintenance, records warranty expiration dates, and tracks vehicle service and registration renewals.
Dynamics Systems has added the capability to track the
length of time tools and equipment have been at a location,
job site, customer, or with an employee. For those companies
who charge equipment usage against jobs, using Checkmate
allows them to maximize profits by correctly recording rental
revenues.
Dynamic Systems has been a national leader in barcode
tracking solutions since 1981, providing flexible, complete,
and configurable programs for: tool and equipment tracking,
document tracking, inventory management, and fixed asset
control. Barcode data collection has been proven to be the
most accurate and efficient method of tracking/counting
items.
“Loss of tools, equipment, and damaged or non-working
equipment are major overhead costs that can be contained
with a well-designed tracking system. Our customers see a
typical payback for the CheckMate Equipment and Tool
Tracking System within three to four months,” states Alison
Falco, president of Dynamic Systems.

NORITZ TANKLESS WATER HEATER
MODELS NOW FEATURED IN
AUTODESK SEEK
Design professionals in the residential and commercial
construction industry can now specify Noritz tankless water
heaters using Autodesk Seek®, an online source for product
specifications and building information modeling (BIM) for
building design. The site now features 10 Noritz products in
its database library.
With the ability to quickly search either by model number or
product name, Noritz products can be embedded directly into
the search bar of major design software used by roughly 80
percent of the industry—including Autodesk® Revit®, AutoCAD®, and Autodesk Design Review.
“Our goal is to make it easier for architects, engineers, contractors, and other professional designers to specify, design,
or build with Noritz tankless water heaters,” says Jason Fleming, marketing manager for Noritz America. “Having the products readily available in Autodesk Seek gives these professionals quick access to information that they would otherwise
have to create themselves. They can simply embed the specified products into the design software, saving them time and
reducing their hassle factor.” !

RED TAG IT
Red tag it: informal interpretation of building codes
The Building Officials Association of Florida, in cooperation with the Florida Building
Commission, the Florida Department of Community Affairs, SBCCI, and industry and
professional experts offer this interpretation of the Florida Building Code in the interest
of consistency in their application statewide. This interpretation is informal, non-binding, and subject to acceptance and approval by the local building official.
PLUMBING
SECTION: 1107.2 & 1107.3
Question: Is it the intent of Section 1107.2 to not allow the
secondary roof drain scupper or drain from a higher roof from
spilling onto a lower roof? If the overflow from a higher roof
can spill onto a lower roof, is the secondary scupper or drain
on the lower roof required to be sized to handle the overflow
from both roof areas?
Comment: The code seems to address only that the secondary roof drain must be a separate system which must discharge above grade in a visible location, but not where the
secondary roof drain can spill onto. The sizing addresses only
the roof area served by the secondary roof drain in relationship to the roof area served by primary roof drain area.
Answer: Yes, it is the intent of Section 1107.2 of the 2010
Florida Building Code Plumbing to not allow a higher roof secondary roof drain scupper to drain from a higher roof spilling
onto a lower roof.
Commentary: The termination of a secondary/emergency
roof drain must be located as to alarm the building occupants
that the primary drain is having issues with flow. If a higher
roof’s secondary drain were allowed to spill onto the lower
roof, the lower roof’s primary drain would pick up the flow, and
this would not alarm the building’s occupants and this intent
is not met.
SECTION: 909.1.1
Question: Section 909.1.1 describes the requirements of a
wet vent system. Is there any limitation on the developed
length of the horizontal section of a wet vent?
Answer: No.
Commentary: There is no limit on the length of the wet vent.
24
JANUARY-FEBRUARY 2014
SECTION: 1002.4 TRAP SEAL
Question: Is it the intent of Section 1002.4 Trap Seal to
require only liquid supplied trap seal devices meeting ASSE
1018 and 1044 to serve floor drains subject to evaporation, or
are trap seal insert devices acceptable for installation in floor
drains to prevent trap evaporation?
Comment: The code does not address the several trap seal
(trap guard) products available today, and local code officials
seem divided on their use.
Answer: Yes, that is the intent.
Commentary: However, alternate methods or materials may
be submitted to the building official for consideration in their
jurisdiction.
MECHANICAL
SECTION: 903
Question: Is it the intent according to the 2010 Florida
Building Code (Mechanical and Energy Conservation Codes)
that when a factory-built, woodburning fireplace is to be
installed into a one- and two-family residence that the factory-built, woodburning fireplace meet the requirements of the
Florida Mechanical Code Section 903, being listed and
labeled in accordance with UL 127 and the Florida Conservation Code Section 402.4.2 which requires new woodburning fireplaces to have gasketed doors and outdoor combustion air? Are both code sections required to be met?
Answer: The Florida Building Commission has issued a DEC
statement regarding this issue. Please go to the website and
pull up DEC Statement DS2013-036.
Commentary: http://www.floridabuilding.org.
SECTION: TABLE 403.3 NOTE H
Question: Is it the intent of note h in table 403.3 that all nail
stations in beauty salons be equipped with a source-capture
ventilation system?
Answer: Yes, footnote (h) reads “For nail salons, the required
exhaust shall include ventilation tables or other systems that
capture the contaminants and odors at their source and are
capable of exhausting a minimum of 50 cfm per station.”
Commentary: This footnote specifically references ventilation
tables. These tables are equipped with an exhaust connection
and some type of capture/containment area to minimize the
amount of odor that may escape into the general salon air.
Further, a duct needs to be extended to the floor, near the feet,
to pick up fumes from pedicures. Other methods acceptable to
the building official may be approved as well.
SECTION: 607.5.4
Question: Is it the intent of code to require smoke dampers
in a duct that serves the corridor along with other spaces outside the corridor if the walls of that corridor are designed as
smoke partitions and the corridor serves as means of egress?
Comment: 607.5.4 calls for smoke dampers in a corridor that
is required to have smoke and draft control doors. It is not
clear which doors those are: Is it every single door leading
into that corridor or some of the doors, for example, cross corridor walls separating smoke compartments? If the goal is to
prevent smoke from being transferred into a corridor used as
means of egress, then the reference to smoke and draft control doors should be eliminated or a better/clearer definition of
the corridor’s enclosures that do require smoke dampers be
provided.
Answer: Yes, if smoke and draft control doors are required.
Commentary: Fire doors with a fire protection rating of 20
minutes are required in corridor walls or smoke barrier walls
required to have a fire resistance rating in accordance with
Table 715.4. When serving more that one function, an element must meet the requirements for all the functions is
serves. In addition to a fire resistance rating, the doors are
also required to meet the requirements for smoke and draft
control door assemblies and be tested per UL 1784
(s.715.4). !
