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.

76,000 BTU (283.9 L - 22.3 kW/ Hr) models. Part II will cover  
venting specifications for 40 Gal - 40,000 BTU (151.4 L - 11.7 kW/  
Hr) and 48 gal - 40,000 BTU (181.7 L - 11.7 kW/ Hr) models. Refer  
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.

DRV1201  
(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:  
TABLE - 2  
Cut a 3-1/2 inch(8.9 cm) diameter hole in the wall at the point where the vent  
connector is going to pass through the wall. Use the proper cement to secure  
the 90° vent terminal provided with the water heater to the vent connector.  
The distance between the edge of the 90° vent terminal and the exterior wall  
(see Figure 3) must be 1 inch(2.5 cm). Use the proper cement and assembly  
procedures to secure the vent connector joints between the terminal and the  
blower outlet. Provide support brackets for every 3 feet (.91 m) of horizontal  
vent.

NOTE: For installations requiring both horizontal and vertical runs,  
the following rule must be followed: Total number of feet of straight  
pipe (both horizontally and vertically) must not exceed the allowable  
length listed in the “Through The Wall” section of the table for total  
number of elbows used. Also: Total number ofvertical feet of straight  
pipe must not exceed the allowable length listed in the “Through The  
Roof” section of the table for total number of elbows used. For  
angular rises in venting, any angle that is greater than or equal to  
45° from the horizontal should be considered a vertical rise.  
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  
that may be hazardous to life. Such a condition often will result in a yellow,  
luminous burner flame, causing carbon build up or sooting of the combustion  
chamber, burners, and flue tubes with possible damage to the heater.

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.  
Confined Spaces  
Confined spaces are spaces defined as having less than 50 ft.3/1000 BTU

Specially Engineered Installations  
The requirements noted under CONFINED SPACES above must not necessarily  
govern when special engineering, approved by the authority having jurisdiction,  
provides an adequate supply of air for combustion, ventilation, and dilution of  
flue gases.  
Note: Some models may already be equipped or supplied with a  
combination temperature and pressure relief valve. Verify that the  
combination temperature and pressure relief valve complies with local  
codes. If the combination temperature and pressure relief valve does  
not comply with local codes, replace it with one that does. Follow the  
installation instructions above on this page.  
WATER CONNECTIONS  
Install a discharge line so that water discharged from the combination  
temperature and pressure relief valve will exit within six (6) inches  
(15.2 cm) above, or any distance below the structural floor and cannot  
contact any live electrical part. The discharge line is to be installed to  
allow for complete drainage of both the combination temperature and  
pressure relief valve and the discharge line. The discharge opening  
must not be subjected to blockage or freezing. DO NOTthread, plug  
or cap the discharge line. It is recommended that a minimum clearance  
of four (4) inches (10.2 cm) be provided on the side of the water  
heater for servicing and maintenance of the combination temperature  
and pressure relief valve.  
Note:  
BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE MAIN WATER SUPPLY VALVE.  
After shutting off the main water supply, open a faucet to relieve the water line  
pressure to prevent any water from leaking out of the pipes while making the  
water connections to the water heater. After the pressure has been relieved,  
close the faucet. The COLD water inlet and HOT water outlet are identified on  
the top of the water heater. The fittings at the cold water inlet and hot water  
outlet are dielectric waterway fittings with 3/4" NPT male thread. Make the  
proper plumbing connections between the water heater and the plumbing  
system to the house. Install a shut-off valve in the cold water supply line.  
Do not place a valve between the combination temperature and pressure  
relief valve and the tank.

WARNING: If you do not follow these instructions exactly, a fire or explosion  
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.  
TEMPERATURE SETTING  
APPROXIMATELY  
120°F (49°C)  
If you cannot reach your gas supplier, call the fire department.  
DANGER  
C. Use only your hand to push in or turn the gas control knob. Never use  
tools. If the knob will not push in or turn by hand, don’t try to repair it,  
call a qualified service technician. Force or attempted repair may result  
in a fire or explosion.  
Hotter water increases the risk of scald injury. Scalding may occur  
within five (5) seconds at a temperature setting of 135°F (57°C). To  
protect against hot water injury, install an anti-scald tempering valve  
in the water system. This valve will reduce point of discharge  
temperature by mixing cold and hot water in branch water lines. A  
licensed plumbing professional or local plumbing authority should be  
consulted.  
D. Do not use this appliance if any part has been under water, immediately  
call a qualified service technician to inspect the appliance and to replace  
any part of the control system and any gas control which has been  
under water.  
Note: This water heater is equipped with an energy cut out device to  
prevent overheating. Should overheating occur or the gas supply fail  
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 Bin 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.

5. Annually remove the inner door and main burner assembly to clean orifices  
and related parts of any dirt or other foreign material. Inspect the burner  
ports for obstructions or debris and clean with a wire brush as needed. Wire  
brush and/or vacuum clean the combustion chamber as needed to remove  
scale deposits and debris. NOTE: It is imperative for proper operation of  
the water heater that the inner door be replaced in the original location.

WARNING  
When lifting lever of the combination temperature and  
pressure relief valve, hot water will be released under  
pressure. Be careful that any released water does not result  
in bodily injury or property damage.  
7. At least once a year, check the combination temperature and pressure  
relief valve to ensure that the valve has not become encrusted with lime.  
Lift the lever at the top of the valve several times until the valve seats  
properly without leaking and operates freely.  
8. Monthly drain off a gallon of water to remove silt and sediment.

9. If the combination temperature and pressure relief valve on the appliance  
discharges periodically, this may be due to thermal expansion in a closed  
water supply system. Contact the water supplier or local plumbing inspector  
on how to correct this situation. Do not plug the combination  
temperature and pressure relief valve outlet.  
10. A combination sacrificial anode rod/hot water outlet nipple has been  
installed to extend tank life.The anode rod should be inspected periodically  
(every 2 years) and replaced when necessary to prolong tank life. Water  
conditions in your area will influence the time interval for inspection and  
replacement of the anode rod. Contact the plumbing professional who  
installed the water heater or the manufacturer listed on the rating plate  
for anode replacement information. The use of a water softener may  
increase the speed of anode consumption. More frequent inspection of the  
anode is needed when using softened (or phosphate treated) water.  
IMPORTANT  
The water heater should be inspected at a minimum annually by a  
qualified service technician for damaged components and/ or joints  
not sealed. DO NOT operate this water heater if any part is found  
damaged or if any joint is found not sealed.  
The following maintenance should be performed by a qualified service technician  
at the minimum periodic intervals suggested below. In some installations, the  
maintenance interval may be more frequent depending on the amount of use  
and the operating conditions of the water heater. Regular inspection and  
maintenance of the water heater and vent-air intake system will help to ensure  
safe and reliable operation.  
11. The induced draft blower has sealed motor bearings and does not require  
adding oil.

d) Cementing must be done quickly to avoid over-drying before joining.  
VENT PIPE PREPARATION AND JOINING  
i) Apply one coat to the outside end of the pipe at a width  
Most failures in PVC, CPVC or ABS systems result from improper preparation and  
joining of pipe and fittings. The guidelines below must be followed when  
installing the venting system. If you have any question about the application  
or installation of the PVC, CPVC or ABS venting system, contact the manufacturer,  
supplier, or your plumbing professional.  
slightly greater than the depth of the socket.  
ii) Apply a coat around the inside of the fitting socket.  
iii) Apply a second coat around the end of the pipe.  
4) Joining  
1) Specific cleaners, solvents, primers and cements are available for PVC,  
CPVC and ABS pipe. Be sure these materials match the type of pipe to be  
installed. Never use all-purpose cements, commercial glues and adhesives  
or ABS cement to join PVC or CPVC pipe and fittings.  
a) Joints should be made immediately after cement is applied.  
b) After fully inserting pipe into fitting socket, give pipe about ¼ turn  
to help spread cement evenly. Hold joint together for about 15 to  
20 seconds.  
a) CLEANERS, SOLVENTS, PRIMERS AND CEMENTS ARE  
FLAMMABLE. Do not store or use these materials near  
heat or open flame, or in the vicinity of other appliances.  
c) Remove excess cement from around pipe and fitting with a clean  
rag.  
2) Use proper cutting, deburring and applicator tools to ensure proper

recommended drying time before disturbing joints.  
a) Cutting Tools  
For more specific and detailed information about the above, contact the  
manufacturer, supplier, or competent professional.  
i) A square cut must be achieved with a miter box saw or pipe  
cutter to ensure a proper mating with the female. If a pipe  
cutter is used, the burr created at the outer edge of the pipe  
must be removed.  
b) Deburring Tools  
i) A file, knife or plastic deburring tool can be used to remove  
burrs. Burrs must be removed from the inside and outside  
edges of the pipe to ensure a proper seal.  
c) Applicator Tools  
i) A pure bristle paintbrush or roller may be used to apply  
cement. Prompt application of the cement is important due  
its fast drying properties.  
3) Inspection, Cleaning, Priming and Cementing  
a) Inspect the pipe inside and out for dirt, dust, moisture or grease  
etc. Check pipe and fittings for splits or cracks and replace if  
necessary.  
b) Clean pipe and fittings are imperative for proper joining. Following  
cutting and deburring, wipe away any foreign material with a clean  
dry rag. If wiping fails to thoroughly clean surfaces, chemical  
cleaning is necessary.  
c) Primer must be applied to the pipe surface and fitting socket with  
a natural bristle brush. This serves to soften and prepare the PVC or  
CPVC for cementing.
