A sacrificial anode is used to extend tank life. The removal of this anode, for
any reason, will nullify the warranty. In areas where water is unusually active,
an odor may occur at the hot water faucet due to a reaction between the
sacrificial anode and the impurities in the water. If this should happen, an
alternative anode may be purchased from the supplier that installed this water
heater. This will minimize the odor while protecting the tank. Additionally, the
water heater should be flushed with appropriate dissolvers to eliminate any
bacteria.

to the rating plate located on the water heater for correct model
identification.
In order to effectively control condensate from adversely affecting the
mechanical components of the water heater several methods may be employed:
1. For horizontal installations the vent pipe can be installed with a downward
slope (not less than 1/8" nor greater than 1/2” per foot maximum) and
away from the blower motor.
The National Fuel Gas Code ANSI Z223.1-(Latest Edition), CGA/CAN B149
Installation Code, and local codes have specific requirements for the location
of the vent terminals on vertical walls. The guide lines listed below are from
the National Fuel Gas Code. Consult the local codes, and/or National Fuel Gas
Code ANSI Z223.1-(Latest Edition), or CGA/CAN B149 Installation Code to
determine if there are any additions or changes to the following specifications.
2. In order to prevent condensate from draining back into the blower (vertical
or horizontal runs), a fitting and drain hose is available as a condensate
trap kit (see Table 1 for service part numbers). The all rubber fitting with
drain outlet mounts directly to the blower motor outlet and is secured with
two hose clamps (one to the blower motor outlet and the other to the vent
connector). The plastic tubing is provided to drain any accumulated
condensate away from the water heater and to a suitable drain. The kit
comes complete with instructions for proper installation of the fitting.
(A) The vent terminal must terminate at least 3 feet (.91 m) above any
forced air inlet duct located within 10 feet (3 m). Exception: This
provision shall not apply to the combustion air intake of a direct vent
appliance.
(B) The vent terminal must terminate at least 4 feet (1.2m) below, 4 feet
(1.2 m) horizontally from, or 1 foot (0.31 m) above any door, window,
gravity air inlet into the building.

(C) The bottom of the vent terminal must be located at least 1 foot
(0.31 m) above ground and above the anticipated snow level.
(D) The vent terminal must not terminate over a public walkway or over an
area where condensate or vapor could create a nuisance or hazard
or could be detrimental to the operation of regulators, relief valve, or
other equipment.
(E) The water heater location must provide easy access for the entire
length of the vent connector.
(F) The vent system must be inspected at least once a year to ensure
against leakage of exhaust products.
3. In order to prevent condensate from draining back into the blower (vertical
or horizontal runs), a drain tee and condensate trap can be installed in the
horizontal vent as close as practical to the blower vent connection (see
Figure1). The condensate disposal tube should be installed to drain any
accumulated condensate away from the water heater and to a suitable
drain. The drain tee and condensate hose should be available through
your local distributor.
Exceptions For Installations in Canada:
(A) The vent terminal must be located at least 1 foot (0.31 m) from any
window or door which can be opened in any building, any non-mechanical
air supply inlet to any building, or the combustion air to any inlet other
appliance.
(B) The vent terminal must be located at least 6 feet (1.8 m) from any
mechanical air supply inlet to the building.
(C) The vent terminal must not terminate above a meter/ regulator
assembly within 3 feet (0.91 m) horizontally of the vertical center line
of the regulator and must be at least 6 feet (1.8 m) from any gas
service regulator vent outlet.
(D) The vent terminal must be at least 7 feet (2.1 m) above a paved
sidewalk or a paved driveway located on public property.
(E) The vent terminal must not terminate above a paved sidewalk or a
paved driveway, which is located on private adjacent property.

VENTING SYSTEM CONDENSATION
Condensate formation does not occur in all installations of power vented
heaters, but should be protected against on installations where condensation
can form in the venting system.
This water heater is a power vented appliance and is designed to vent its
products of combustion through 3" (7.6 cm) or 4" (10.2 cm) diameter Schedule
40 (solid or cellular core) PVC pipe to the outdoors. This water heater may be
either vented through the wall or vertically through the roof. Use a 3" (7.6 cm)
Formation of condensation in the venting system of Power Vented water
heaters is dependent upon installation conditions including, but not limited to: to 4" (10.2 cm) reducer to connect to the vent outlet when using 4" (10.2 cm)
PVC. Table 2 lists the maximum vent lengths for this water heater using 3" (7.6
cm) PVC. If possible, locate the water heater so that the venting length and
number of elbows are kept to the minimum distance necessary to reach the
outside. If the installation requires venting lengths that exceed the lengths
listed for 3" (7.6 cm) PVC in Table 2, then use 4" (10.2 cm) PVC for the vent
connector. Table 3 lists the venting distances allowed with 4" (10.2 cm)

diameter PVC pipe. When venting with 4" (10.2 cm) PVC, use a 4" (10.2 cm) to
3" (7.6 cm) reducer to exit through the building wall with 3" (7.6 cm) PVC. Use
the 3" (7.6 cm) vent terminal supplied with the water heater to terminate on
the outside of the building. If the length of 3" (7.6 cm) PVC needed to go
through the wall is greater than 14" (35.5 cm), use 4" (10.2 cm) to go through
the wall and reduce to 3" (7.6 cm) PVC immediately after exiting the outside
wall. Refer to the venting illustrations on the following pages. Make sure the
vent pipe terminal elbow fitting is at least 1" (2.5 cm) away from the edge of
the wall.
IMPORTANT
All of the Venting connections must be leak checked with a soap and
water solution upon initial start up of the water heater. Any leaks
must be repaired before continuing operation of the water heater.
NOTE: ABS or CPVC pipes may be substituted for PVC pipe. Do not
mix ABS and PVC pipe in the same installation.
THROUGH THE WALL VENTING:

COMBUSTION AIR SUPPLY
WARNING
Liquefied petroleum gases/propane gas are heavier than air and will remain
at floor level if there is a leak. Basements, crawl spaces, closets and areas
below ground level will serve as pockets for accumulation of leaking gas.
Before lighting, smell all around the appliance area for gas. Be sure to smell
next to the floor.
WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electrical switch; do not use any telephone
in your building.
• Immediately call your gas supplier from a neighbor’s
telephone. Follow the gas supplier’s instructions.

IMPORTANT
The flow of combustion and ventilating air must not be obstructed.
Provide adequate air for combustion and ventilation. An insufficient supply of
air will cause recirculation of combustion products resulting in air contamination

Unconfined Spaces
In unconfined spaces in buildings, infiltration may be adequate to provide air
for combustion, ventilation, and dilution of flue gases. However, in buildings of
tight construction (for example, weather stripping, heavily insulated, caulked,
vapor barrier, etc.), additional air may need to be provided using the methods
described under CONFINED SPACES: All Air From Outdoors or Specially Engineered
Installations.
HIGH ALTITUDE INSTALLATIONS FOR ELEVATIONS OVER 2,000 FEET
(610 m) ABOVE SEA LEVEL
The capacity of the induced draft blower declines with increasing altitude due to
a reduction in the air density. In order to assure safe and reliable performance
of the water heater, the following guidelines must be followed. Refer to the
venting tables below for maximum distances for the altitudes in your location.

may result causing property damage, personal injury or loss of life.
A. This appliance is equipped with an ignition device which automatically
lights the pilot. Do not try to light the pilot by hand.
TEMPERATURE DIAL
B. BEFORE OPERATING smell all around the appliance area for gas. Be
sure to smell next to the floor because some gas is heavier than air and
will settle on the floor.
WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electric switch; do not use any telephone in your
building.
• Immediately call your gas supplier from a neighbor’s phone. Follow
the gas supplier’s instructions.

to shut off, turn off the manual gas control valve to the appliance and
call a qualified service technician.
OPERATING INSTRUCTIONS
1. Stop! Read the safety information above on this label.
2. Turn off all electric power to appliance.
Note: Whenever the water heater is filled with cold water, condensate
will form on the cool tank surface and drops of water will fall on the hot
burner and combustion chamber surfaces producing a “sizzling” noise.
Condensation is normal and does not indicate a leak. It will disappear
when the tank becomes heated.
3. Set the thermostat to the lowest setting.
4. This appliance is equipped with on ignition device which automatically
lights the pilot. Do not try to light the pilot by hand.
5. Slide the switch on the left side of the gas valve to the “OFF” position.
6. Wait five (5) minutes to clear out any gas. Then smell for gas,
including near the floor. If you smell gas, STOP! Follow “B” in the
safety information above on this table. If you don’t smell gas, go to the
next step.
7. Slide the switch on the left side of the gas valve to the “ON” position.
8. Set thermostat to desired setting.
BURNER FLAME CHECK
9. Turn on all electric power to the appliance.
10. If the appliance will not operate, follow the instructiolns “To Turn Off Gas
To Appliance” and call your service technician or gas supplier.
Cast Iron Burner: At the time of installation and at periodic intervals (not
more than 6 months), a visual check of the main burner and pilot flames
should be made to determine if they are burning properly. For ideal operation,
the gas and air must be properly proportioned. The proper air-gas mixture is
obtained by adjusting the air shutter on the mixer face of the main burner (See
Figure 14). To adjust for proper burning, loosen the air shutter nut (if provided),
rotate shutter to close the opening in the burner then slowly rotate the shutter
until the yellow tips disappear and the flame becomes blue. On 75 gallon
models fired on LPG or propane, adjust the air shutter as described above until
the yellow flame is minimized (note-the burner flame may contain a mixture of
yellow and blue). Tighten the air shutter nut. Too much air will cause the flame
to lift off the burner ports and create noisy operation. Too little air will result in
soot formation. The main burner flame should light smoothly from the pilot.
TO TURN OFF GAS TO APPLIANCE
1. Turn off all electric power to the appliance.
2. Set the thermostat to lowest setting.
3. Slide the switch on the left side of the gas valve to the “OFF” position.
THERMOSTAT ADJUSTMENT
CAUTION
Before adjusting thermostat(s), turn off power supply to the water heater.
The thermostat dial is adjusted to approximately 120°F when shipped from the
factory. When adjusting the thermostat, it should be remembered that lower
temperature settings are more energy efficient. The thermostat cover, on the
right side of the gas valve, must be removed when the thermostat is adjusted.
To adjust the thermostat turn the dial colckwise with a screwdriver until the
minimum acceptable temperture is set. It is suggested that the starting point
setting not exceed the 120°F (49°C) or “HOT” setting on the thermostat.
Steel Burner: These models are equipped with self adjusting air mixture and
do not have an adjustable air shutter (See Figure 14). At periodic intervals a
visual check of the main burner and pilot flames should be made to determine
if they are burning properly. The main burner flame should light smoothly from
the pilot.
