SAFETY INSTRUCTIONS (Continued)
This appliance is equipped with an uncon-
ventional gas control valve that is factory set with a mani-
fold pressure of -.2 inches wc. Improper installation,
adjustment, alteration, service or maintenance can cause
property damage, personal injury or loss of life.
Installation or service must be performed by a qualified
installer, service agency or the gas supplier. If this control is
replaced, it must be replaced with an identical control.
Do not attempt to adjust the gas flow by adjusting the reg-
ulator setting.
Risk of fire or explosion from incorrect fuel
use or faulty fuel conversion. Do not try to run a heater set
up for natural gas on propane gas or vice versa. Only qual-
ified service technicians should attempt to convert heater
from one fuel to the other.
Do not attempt to alter the rated input or type of gas by
changing the orifice. If it is necessary to convert to a different
type of gas, consult your Sta-Rite dealer. Serious malfunction
of the burner can occur which may result in loss of life. Any
additions, changes, or conversions required in order for the
appliance to satisfactorily meet the application needs must be
made by a Sta-Rite dealer or other qualified agency using
factory specified and approved parts.
The heater is available for use with natural gas. It can be
converted to propane gas. Refer to the nameplate for the
type of gas the heater is equipped to use.
Use this heater only with natural gas. Do not attempt to
convert it to another type of gas.
If propane gas is the only available fuel, have a qualified
service technician convert the heater to propane before
putting heater into operation.
Risk of fire or explosion from flammable
vapors. Do not store gasoline, cleaning fluids, varnishes,
paints, or other volatile flammable liquids near heater or in
the same room with heater.
Risk of fire, carbon monoxide poisoning, or
asphyxiation if exhaust venting system leaks. Only quali-
fied service technicians should attempt to service the
heater, as leakage of exhaust products or flammable gas
may result from incorrect servicing.
Risk of explosion if unit is installed near
propane gas storage. Propane (LP) gas is heavier than air.
Consult local codes and fire protection authorities about
specific installation requirements and restrictions. Locate
the heater away from propane gas storage and filling equip-
ment as specified by the Standard for the Storage and
Handling of Liquified Petroleum Gases, CAN/CSA B149.2
(latest edition) or ANSI/NFPA 58 (latest edition).
Risk of asphyxiation if exhaust is not correct-
ly vented. Follow venting instructions exactly when
installing heater. Do not use a draft hood with this heater,
as the exhaust is under pressure from the burner blower
and a draft hood will allow exhaust fumes to blow into the
room housing the heater.
The heater is supplied with an integral venting system for
outdoor installation. A vent conversion kit (See Page 14 for
Part Numbers for Conversion Kits) is available for installa-
tions in enclosures (Canada) or indoors (U.S.). Use the
specified venting, and only the specified venting, when
heater is installed in an enclosure or indoors. In Canada,
this pool heater can only be installed outdoors or in an
enclosure that is not normally occupied and does not
directly communicate with occupied areas. See Page 11 for
enclosure venting requirements.
Label all wires prior to disconnection when
servicing controls. Wiring errors can cause improper and
dangerous operation. Wiring errors can also destroy the
control board.
Connect heater to 120 or 240 Volt, 60 Hz., 1 Phase power
only.
Verify proper operation after servicing.
Do not allow children to play on or around heater or asso-
ciated equipment.
Never allow children to use the pool or spa without adult
supervision.
Read and follow other safety information contained in this
manual prior to operating this pool heater.
GENERAL SPECIFICATIONS/
REQUIREMENTS
NOTICE: Combustion air contaminated by corrosive chemi-
cal fumes can damage the heater and will void the warranty.
NOTICE: The Combination Gas Control Valve on this
appliance differs from most appliance gas controls. If it
must be replaced, for safety reasons replace it only with an
identical gas control.
NOTICE: The jacket covers must be in place to provide
proper ventilation. Do not operate the heater for more than
five (5) minutes with the jacket covers removed.
This heater is design certified by CSA International as com-
plying with the Standard for Gas Fired Pool Heaters, ANSI
Z21.56* CSA 4.7, and is intended for use in heating fresh
water swimming pools or spas.
NOTICE: Do not use this heater as a heating boiler, water
heater, or for heating salt-water pools. This heater is
intended for use in heating fresh water swimming pools or
spas only.
The heater requires an external 120 or 240 VAC single-
phase electric power source.
The heater is design certified by CSA International for
installation on combustible flooring. Specified minimum
clearances must be maintained to combustible surfaces
(see “Installation Instructions”, Pages 9 and 10).
The heater should be located in an area where leakage of
the heater or connections will not result in damage to the
area adjacent to the heater or to the structure. When such
locations cannot be avoided, it is recommended that a suit-
able drain pan, adequately drained, be installed under the
heater. The pan must not restrict air flow.
3
The heater may not be installed within five feet of the
inside surface of a pool or spa unless it is separated by a
solid fence, wall or other permanent barrier.
Propane (LPG) fired heaters must not be installed in
Massachusetts, by order of the Massachusetts State Fire
Marshall. For more information, call the Fire Marshall’s
office.
DESCRIPTION OF THE HEATER
Figure 2 is a diagram of the heater showing how it operates.
Precisely matched orifice plates meter the air and gas into
the mixer. The blower draws the air and gas through the
mixer and forces it into the burner’s flameholder. A sealed
heat exchanger surrounds the flameholder, discharging
exhaust gases out the flue.
Two inch PVC water piping connects directly to the mani-
fold/header on the heat exchanger using 2” PVC slip unions
provided with the heater. The outer manifold remains cool;
no heat sinks are required. A thermal regulator and an inter-
nal bypass regulate the water flow through the heat
exchanger to maintain the correct outlet temperature.
A plastic jacket with the top half split for access surrounds
the assembly. The heater control board assembly, set into
the top of the jacket, contains the operating controls.
SEQUENCE OF OPERATION
An electronic temperature sensing thermistor in the mani-
fold adapter inlet controls the heater operation. When the
inlet water temperature drops below the temperature set on
the operating control, the burner controller supplies
power to the combustion air blower through a series of
safety interlocks. The interlocks consist of
the pressure switch (PS), which senses that the pump is
running,
the high limit switch (HLS), which opens if the heat
exchanger outlet temperature goes above 135°F
(57°C), and
the automatic gas shutoff (AGS) switch, which opens
if the heat exchanger outlet temperature goes above
140°F (60°C).
the stack flue sensor (SFS), which shuts down the heater
if the flue gas temperature reaches 500°F (260°C).
The air flow switch (AFS) senses the pressure drop across
the air metering orifice. As soon as there is sufficient air
flow, the AFS closes, closing the circuit to the hot surface
igniter (HSI), which ignites the fuel mixture.
On a call for heat, the blower and HSI are energized. In
about 20 seconds, the gas valve opens and ignition occurs.
The HSI then switches to a sensing mode and monitors the
flame.
The heater is equipped with a digital operating control that
enables the user to pre-set the desired pool and spa water
temperatures. The control enables the user to select
between pool and spa heating, and features a digital dis-
play that indicates the water temperature.

F. Before operating the appliance for the first time or after
it has been off for an extended time, perform the fol-
lowing checklist:
1. Remove debris or other articles from inside the
heater and the area around the heater and its
exhaust vent. Make sure the ventilation openings are
clear of debris or obstruction. For installations in an
enclosed space, make sure openings for combustion
and ventilation air are unobstructed.
2. Keep heater area clear and free from combustibles,
flammable liquids and chemicals.
3. Check that all water connections are tight.
4. Water must be flowing through the heater during
operation. Make sure that pool/spa is filled with
water and have pump operating. Check that water
flow is unobstructed from the appliance. When
operating for the first time or after an extended shut-
down, run filter pump for several minutes to clear
all air from the system.
SPA TEMPERATURE CAUTION
All safety rules recommended by the U.S. Consumer
Product Safety Commission should be observed when
using a spa or hot tub, including:
1. Spa or hot tub water temperatures should never exceed
104°F (40°C). A temperature of 100°F (38°C) is consid-
ered safe for a healthy adult. Special caution is sug-
gested for young children.
2. Drinking of alcoholic beverages before or during spa
or hot tub use can cause drowsiness which could lead
to unconsciousness and subsequently result in
drowning.
3. Pregnant women beware! Soaking in water above
102°F (39°C) can cause fetal damage during the first
three months of pregnancy (resulting in the birth of a
brain-damaged or deformed child). Pregnant women
should follow the 100°F (38°C) maximum rule.
4. Before entering the spa or hot tub, users should check
the water temperature with an accurate thermometer;
spa or hot tub thermostats may err in regulating water
temperature.
5. Persons with medical history of heart disease, circula-
tory problems, diabetes or blood pressure problems
should obtain their physician’s advice before using
spas or hot tubs.
6. Persons taking medications which induce drowsiness,
such as tranquilizers, antihistamines or anticoagulants,
should not use spas or hot tubs.

12. Press either the POOL ON or SPA ON button switches
on the operating control.
13. Set the thermostat to desired setting (NOTICE: Set
point must be above actual water temperature or burn-
er will not fire). See OPERATING CONTROL below.
14. The blower should come on immediately, and after
about 20 seconds, the burner should fire. When oper-
ating for the first time, the burner may not fire on the
first try because of air in the gas line. If it does not fire
at first, push the OFF switch, wait five minutes, and
again push the POOL or SPA ON switch. The burner
should fire after about 20 seconds. You may have to
repeat this until all of the air has cleared the gas line.
15. The burner should fire until the pool/spa temperature
reaches the desired temperature set on the thermostat.
The blower will continue to run for about 45 seconds
after the burner shuts off. If any of the safety interlocks
should open during burner operation, the burner shuts
off immediately, but the blower continues to run for
about 45 seconds.
Should overheating occur or the gas supply fail to
shut off, turn off the manual gas control valve to the

the digital display will indicate the temperature setting.
After five seconds, the display will return to the actual
pool/spa temperature.
In addition to the digital temperature display, there are five
indicator lights:
The POOL ON light indicates that the pool water tempera-
ture is governing operation of the heater.
The SPA ON light indicates that the spa water temperature
is governing operation of the heater.
The HEATING light comes on and stays on when the burn-
er is firing. This light should be on whenever the burner is
on. It blinks when the heater is calling for heat but not fir-
ing. If this light is on but the burner fails to come on, one
of the “service” lights should come on, indicating a fault in
the system.
The SERVICE SYSTEM light indicates that there is insuffi-
cient water flow to the heater. If the pump is operating, this
usually indicates that the filter and/or skimmers should be
cleaned (some filters may require backwashing). If the light
remains on after the filter/skimmers have been serviced,
the system should be checked by a qualified service tech-
nician.
The SERVICE HEATER light indicates a fault in the heater
or its controls. If this light comes on, shut down the heater
(See TO TURN OFF GAS TO THE APPLIANCE, at left), and
have a qualified service technician check the system.
Risk of explosion or fire causing burns or
death if safety interlocks are disabled. DO NOT attempt to
operate heater when SERVICE HEATER light is on or if
blower or burner will not start. Instead, follow instructions
under “To Turn Off Gas to the Appliance”, at left, and call
a qualified service technician to repair unit.
AFTER START-UP
CHECKING WATER FLOW
Fire or flooding hazard. If the unit overheats
and the burner fails to shut off, follow instructions under
“To Turn Off Gas to the Appliance”, Page 6, and call a
qualified service technician to repair unit.
After start-up, the outlet water pipe should feel slightly
warmer than the inlet pipe. If it feels hot, or if you hear the
water in the heater boiling, there may not be enough water
flow to the appliance. Make sure that the filter is not
plugged. If water temperature remains high but the unit
continues to operate, turn off the appliance and call your
service technician.
SPRING AND FALL OPERATION
If the pool is only used occasionally, lower the pool ther-
mostat to 65°F (18°C). and leave the heater on. This will
keep the pool and the surrounding ground warm enough
so that the heater should restore the pool to a comfortable
temperature within about one day.
COLD WEATHER OPERATION
The heater may be operated in the wintertime, provided air
temperatures remain above freezing and the water temper-
ature is not permitted to drop below 65°F (18°C). Extended
heater operation with water temperatures below 65°F
(10°C) can result in serious damage to the heater and is not
covered by warranty.
NOTICE: When starting the heater for the swimming season
with a water temperature below 50°F (10°C), the heater may
be used to heat the water; however, make sure that the
heater operates continuously until the water temperature
reaches the heater’s minimum setting of 65°F (18°C).
DO NOT operate this unit outdoors at temperatures below
40°F (4°C).
During cold weather, if there is no danger of freezing,
operate the filter pump continuously even if the heater is
not operating. If air temperatures are expected to drop
below freezing (32°F/0°C), shut down the heater and win-
terize it (See ”WINTERIZING”, Page 8). Allowing the
heater to freeze will void the warranty.
MAINTAINING POOL TEMPERATURE
To maintain pool temperature, make sure that the heater
switch and valving are reset to pool settings after using the
spa.
ENERGY SAVING TIPS
1. Keep the pool or spa covered when not in use. This will
reduce heating costs, reduce water evaporation, con-
serve chemicals and reduce load on the filtering system.
2. Reduce pool thermostat to 78°F (25°C) or lower;
reduce spa temperature to 100°F (38°C).
3. Use a time clock to start the filter pump at 6 a.m. or
later. The swimming pool loses less heat after daybreak.
4. For pools used only on weekends, lower the thermostat
setting by 10°F to 15°F (5°C to 8°C) during the week to
reduce heat loss. A properly sized heater will restore
normal temperature within one day.
5. Turn the heater off when the pool will not be used for
an extended period.
6. Follow a regular program of preventive maintenance
for the heater each new swimming season. Check
operation of the heater and its controls.
7
CARE AND MAINTENANCE
MAINTENANCE INSTRUCTIONS
Risk of fire or explosion from flammable
vapors. Do not store gasoline, cleaning fluids, varnishes,
paints, or other volatile flammable liquids near heater or in
the same room with heater.
The following maintenance is recommended every six
months and at the start of every swimming season:
1. Inspect the jacket and venting system to make sure that
there are no obstructions to the flow of ventilating air
or burner exhaust. Check that room air intakes are
open and clear of obstructions.
2. Keep the area in and around the heater clear and free
from combustible materials, gasoline and other flam-
mable vapors and corrosive liquids.
3. Test the operation of the pressure relief valve by lifting
the valve lever.
4. Test for proper operation of the pressure switch. (See
“SWITCH SETTINGS” for testing instructions).
5. On enclosed installations with high-temperature
Special Gas Vent systems, repeat the Final Installation
Check, Page 15. Check for evidence of joint leakage.
Make sure that joints have not slipped partially or
completely apart. Check pipe and fittings for cracks or
breaks.
The combustion air blower is permanently lubricated,
and does not require periodic lubrication. The burner does
not require maintenance or adjustment by the user. Call a
qualified service technician if you suspect that the burner
may require maintenance.
WINTERIZING (See Figure 7)
For outdoor heaters in freezing climates, shut the heater
down and drain it for winter as follows:
1. Turn off electrical supply to the heater and pump.
2. Close main gas control valve and manual gas valve
(located outside the heater).
3. Open drain cock located on the bottom of the mani-
fold adapter, and drain the heat exchanger and mani-
fold adapter completely. If heater is below pool water
level, be sure to close isolation valves to prevent drain-
ing the pool (isolation valves are not required and
should not be used on heaters installed above pool
water level). Assist the draining by blowing out the
heat exchanger through the pressure switch fitting with
low pressure compressed air (less than 5 PSI or
35 kPa).
Explosion hazard. Purging the system with
compressed air can cause components to explode, with
risk of severe injury or death to anyone nearby. Use only
a low pressure (below 5 PSI or 35 kPa), high volume blow-
er when air purging the heater, pump, filter, or piping.
4. Remove the Water Pressure Switch. Plug the port in the
manifold to prevent bugs and dirt from getting into the
manifold.
5. Drain the plastic inlet/outlet manifold through the out-
let pipe. If the pipe does not drain naturally to the
pool, install a drain cock in the outlet pipe to drain the
manifold.
6. Cover air inlet grate with a plastic bag to prevent bugs,
leaves, etc., from getting into the heater.
NOTICE: Water trapped in the heater can cause freeze
damage. Allowing the heater to freeze voids the warranty.
To return the heater to service after winterizing:
1. Close drain cock and fittings.
2. Before starting the heater, circulate water through the
heater for several minutes until all air noises stop.

INSTALLATION INSTRUCTIONS
Risk of fire, explosion, or asphyxiation if
heater is improperly installed, adjusted, serviced or main-
tained.
These instructions are for licensed, certified, trained and
experienced installers only. Be sure your installer or service
technician holds all required licenses or certification for
your area. Attempts by unqualified persons to service or
repair this heater are dangerous and could be fatal.
PUTTING THE HEATER INTO SERVICE
If the heater is installed below the level of the pool, or
more than two feet above pool level, the pressure switch
setting should be adjusted. See PRESSURE SWITCH, in the
MAINTENANCE section.
Before putting the heater into service for the first time, fol-
low the instructions under BEFORE STARTUP in the front
of this manual. Check for proper operation of the heater by
following the steps under OPERATING INSTRUCTIONS.
Damage to equipment caused by improper installation or
repair will void the warranty.
OUTDOOR INSTALLATION INSTRUCTIONS
For heaters located outdoors, using the built-in stackless
venting system.
Risk of explosion if a unit converted to
propane gas is installed in a pit or other low spot. Propane is
heavier than air. Do not install the heater using propane in
pits or other locations where gas might collect. Consult your
local building code officials to determine installation require-
ments of heater relative to propane storage tanks and filling
equipment. Installation must meet the requirements of the
Standard for the Storage and Handling of Liquid Petroleum
Gases, ANSI/NFPA 58 (latest edition) in the U.S., or CAN/CSA
B149.2 (latest edition) in Canada. Consult local codes and fire
protection authorities about specific installation restrictions.
Locate the heater on a level surface in an open area that is
protected from drainage or run-off. Install the heater in an
area where leaves or other debris will not collect on or
around the heater. Do not install the heater where water
(including sprinklers or runoff) will fall directly onto the
jacket.
HEATER CLEARANCES – OUTDOOR
The heater must be installed with the top of the vent at
least 10 feet (3M) below, or to either side of, any opening
into a building.
If the heater is located under a roof or deck overhang,
there must be at least three feet (1M) clear space between
the bottom of the overhang and the top of the heater
exhaust vent. The heater must be at least six inches (15cm)
from the nearest wall (clearance for service access will
depend on the installation). If the heater is under a roof or
deck overhang, the space around the heater must be open

OUTDOOR SHELTER
INSTALLATION INSTRUCTIONS
This pool heater can only be installed outdoors or in an
enclosure that is not normally occupied and does not
directly communicate with occupied areas.
Risk of asphyxiation if exhaust is not correct-
ly vented. Follow venting instructions exactly when
installing heater. Do not use a draft hood with this heater,
as the exhaust is under pressure from the burner blower
and a draft hood will allow exhaust fumes to blow into the
room housing the heater. Exhaust venting to the outdoors is
required for all outdoor shelter installations.
Risk of explosion if a unit converted to
propane gas is installed in a pit or other low spot. Propane is
heavier than air. Do not install the heater using propane in
pits or other locations where gas might collect. Consult your
local building code officials to determine installation require-
ments of heater relative to propane storage tanks and filling
equipment. Installation must meet the requirements for the
Standard for the Storage and Handling of Liquified Petroleum
Gases, CAN/CSA B149.2 (latest edition) or ANSI/NFPA 58
(latest edition). Consult local codes and fire protection
authorities about specific installation restrictions.
The heater is design certified by CSA International for
installation on combustible flooring; in alcoves; basements;
in closet or utility rooms (in the U.S.)
INSTALLATION IN A GARAGE
OR UTILITY ROOM
In Canada, this must be not normally occupied and must
not directly communicate with occupied areas.
Risk of fire and explosion if installed at floor
level in an automotive garage or near gasoline or flamma-
ble liquid storage. Gasoline fumes are heavier than air and
will settle to floor level in closed spaces. Gasoline fumes
and spilled gasoline or other volatile liquids (such as some
paints and varnishes) will travel across the floor and can be
ignited by a gas appliance. In a utility room or residential
garage installation, install the heater with the base at least
18 inches (.5M) above the floor. In a garage, install a rail
or wall to protect the heater from physical damage by a
moving vehicle.
Provide an adequate ventilation air supply (See Table 2,
Page 11). Choose a location that will avoid contamination
by chemical fumes.
NOTICE: PROPANE (LPG) fired heaters must not be
installed in garages in Massachusetts, by order of the
Massachusetts State Fire Marshall. For more information,
call the State Fire Marshall’s office.
NOTICE: Combustion air contaminated by corrosive
chemical fumes can damage the heater and will void the
warranty (See Table 1, Page 11).

The following clearances must be maintained from com-
bustible surfaces:
TOP ...........................6 INCHES (15cm)
ALL SIDES..................6 INCHES (15cm)
VENT .........................6 INCHES (15cm)
The heater is design certified by CSA International for
installation on combustible flooring. For installation on car-
peting, the heater must be mounted on a metal or wood
panel that extends at least three inches (10cm) beyond the
base of the heater. If the heater is installed in a closet or
alcove, the entire floor shall be covered by the panel.
On an outdoor shelter installation, the exhaust discharges
into a vent pipe. Orient the heater so that the vent pipe does
not interfere with adjustment of the operating controls. The
operating control panel located on top of the jacket can be
rotated for convenient access to the control panel.
COMBUSTION AND VENTILATION AIR SUPPLY
For shelter installation, the heater requires air supply open-
ings for ventilation and combustion. The minimum require-
ments are for two (2) openings: one 12 inches (30cm) from
the ceiling for ventilation air and one 12 inches (30cm) from
the floor for combustion air, in accordance with the latest
edition of ANSI Z223.1, or the National Fuel Gas code, the
CSA B149.1, Natural Gas and Propane Installation Codes, as
applicable, and any local codes that may apply.
The minimum net free area in square inches shall be
as follows:
OUTDOOR SHELTER VENT
INSTALLATION (Canada) or
INDOOR INSTALLATION (U.S.)
Always vent the heater to the outdoors.
•Vent it horizontally or vertically using a Special Gas
Vent, (see Table 4, Page 14), or
•Vent it vertically using Type “B” double wall vent con-
nector pipe.
Locate the heater so as to minimize the length of horizon-
tal venting and the number of vent elbows required.
Horizontal vent runs must slope up 1/4” per foot (2cm/M)
from the heater to allow exhaust condensate to drain and
must have a condensate drain as described in the venting
installation instructions.

OUTSIDE VENT COVER REMOVAL
The heater is supplied from the factory with a built-in
stackless outside vent for outdoor installation. Remove the
outside vent cover for outdoor shelter installation.
VERTICAL VENTING - NEGATIVE PRESSURE
(See Figures 11 and 12)
Vent the heater vertically in a negative pressure (positive draft)
system in accordance with the National Fuel Gas Code, ANSI
Z223.1/NFPA 54 and/or CSA B149.1, National Gas and
Propane Installation Codes, and local codes. Type “B”
Double-wall vent connector is recommended; however sin-
gle-wall pipe is allowed by the National Fuel Gas Code in
some circumstances. Consult your local code official for
detailed information. Do not use a draft hood with this heater.
To connect a negative pressure metal gas vent to the
heater, order the appropriate Metal Flue Collar from the
chart below:
1. See Table 3, below, to determine allowable vent sizes
for your heater.
NOTICE: Table 3 is for installations in which the total later-
al vent length (that is, the horizontal distance from the flue
collar to the main vertical portion of the vent) is less than
1/2 the total vent height (the vertical distance from the flue
collar to the vent termination) and which have three or less
elbows in the system. For venting systems which do not
meet these conditions, consult the National Fuel Gas
Code, ANSI Z223.1 (U.S.), or the standards CSA B149.1
and B149.2 (Canada).
2. Install the metal Flue Collar in the Vent Body of the
heater (located under the outside vent cover). Fasten the
metal Flue Collar to the Vent Body with two #10 sheet
metal screws. Use UltraCopper
®
silicone RTV to seal the
Flue Collar to the Vent Body. Before connecting the
metal Flue Collar to the Vent Body, wet a clean cloth or
paper towel with isopropyl alcohol (rubbing alcohol) and
vigorously wipe the socket of the Vent Body.
Immediately wipe the cleaned surfaces dry with a clean
cloth or paper towel. Repeat for the exterior of the 4”
end of the metal Flue Collar. Attach the metal Flue Collar
to the Vent Body using the RTV supplied with the kit, fol-
lowing the vent manufacturer’s instructions (included
with kit). Do not use a draft hood with this heater.
3. Attach the vent pipe to the metal Flue Collar with
sheet-metal screws.
Risk of fire or asphyxiation if vent is not
assembled according to manufacturer’s instructions or if
vent parts from different manufacturers are mixed. Vent
parts from different manufacturers ARE NOT interchange-
able. Mixing parts from more than one manufacturer may
cause leaks or damage to vent. When assembling a vent,
pick one manufacturer and be sure that all vent parts come
from that manufacturer and are specified by the manufac-
turer for your system. Follow manufacturer’s instructions,
local code requirements, National Fuel Gas Code require-
ments (U.S.) or standards CSA B149.1 and B149.2
(Canada) carefully during assembly and installation.
4. Install vent pipe so that it can expand and contract
freely as the temperature changes. Support the vent pipe
according to applicable codes and the vent manufactur-
er’s instructions. Pipe support must allow the vent pipe
free movement out and back, from side to side, or up
and down as necessary, without putting a strain on the
heater or vent body. Slope horizontal pipe runs up from
the heater at least 1/4” per foot (2cm per meter). Install
Listed condensate drains at low points where conden-
sate might collect. Plumb condensate drains to a drain
through hard piping or high-temperature tubing such as
silicone rubber or EPDM rubber – do not use vinyl or
other low temperature tubing. Follow drain manufactur-
er’s installation instructions.
