WARNING  
DO NOT ATTEMPT TO LIGHT ANY GAS APPLIANCE IF YOU ARE NOT  
CERTAIN OF THE FOLLOWING:  
·
Liquefied petroleum gases/propane gas and natural gas have an odorant  
added by the gas supplier that aids in detection of the gas.  
Most people recognize this odor as a “sulfur” or “rotten egg” smell.  
Other conditions, such as “odorant fade” can cause the odorant to  
diminish in intensity, or “fade”, and not be as readily detectable.  
If you have a diminished sense of smell, or are in any way unsure of t
presence of gas, immediately contact your gas supplier from a  
neighbor’s telephone.  
·
·
·
·
Gas detectors are available. Contact your gas supplier or plumbing  
professional for more information.  
Proper venting practices must be considered when selecting a location for this  
water heater. For exact venting specifications, please consult the Venting  
section of these Installation and Operating Instructions.  
The appliance should be located in an area where leakage of the tank or  
connections will not result in damage to tharea adjacent to the appliance or to  
lower floors of the structure. When sucocations cannot be avoided, it is  
recommended that a suitable drain pan, adequately drained, be installed under  
the appliance. The pan must not restrict combustion air flow.

VENTING  
WARNING  
The vent system must be installed properly. Failure to properly install the  
vent system could result in property damage, personal injury, or death.  
Place the draft diverter over the flue opening at the top of the water heater by  
inserting the tips of the draft diverter legs into the four (4) holes provided in the  
water heater top. On some models, line up the holes in the draft diverter le
with the holes provided on top of the water heater. Secure the draft diverter to  
the water heater with sheet metal screw. (See Figure 5)  
Vent piping must be attached to the draft diverter outlet to connect the water  
heater to the gas vent or chimney. The following minimum learances must be  
followed when connecting vent piping:  
a) The vent connector must be the same nominal size as the draft  
diverter.  
b) The vent connector should not exceed 15 feet (4.5m) in length (for  
power vent appliances, refer to supplemental instructions), must not  
project into the chimney beyond the inr wall and should contain the  
least possible number of bends.  
c) All horizontal runs should have a minimum rise of ¼ inch(2.1cm/m) per  
foot of run.  
d) Joints of vent connectors shall be securely fastened by sheet metal  
screws or other appromethods.  
e) All single wall vent connectors must be at least 6” (15cm) from  
combustible suraces.  
f) Vent connectors made of single-wall metal pipe shall not pass

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.  
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 telephone. Follow  
the gas supplier’s instructions.  
If you cannot reach your gas supplier, call the fire department.  
DO NOT OPERATE APPLIANCE UNTIL LEAKAGE IS CORRECTED!  
IMPORTANT  
The flow of combustion and ventilating air musnot be obstructed.  
·
Do not block or in any way restrict cket air inlet slots located the  
bottom front of the water heater.  
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 lifeuch a condition often will result in a yellow,  
luminous burner flame, causing carboning or sooting of the combustion  
chamber, burners and ue tubes with possible damage to the water heater.  
When an exhaust fan is installed in the same room with a heater, sufficient  
openings for air must be provided in the walls. Undersized openings will cause  
air to be drawn into the room through the chimney, causing recirculation of  
combustion products.  
Confined Spaces  
Conined spaces are spaces defined as having less than 50 ft.3 of space per  
1,000 BTU (15m3/.29kw) per hour of input.  
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 above under CONFINED SPACES: All Air From Outdoors or  
SPECIALLY ENGINEERED INSTALLATIONS.

Installation (continued)-  
All Air From Inside the Building: The confined space shall be provided with  
two permanent openings communicating directly with an additional room(s) of  
sufficient volume so that the combined volume of all spaces meets the criteria  
for an unconfined space. The total input of all gas utilization equipment installed  
in the combined space shall be considered in making this determination. Each  
opening shall have a minimum free area of 1 square inch per 1000 BTU  
(2.54cm2/.29kw) per hour of the total input rating of all gas utilization equipment  
in the confined space, but not less than 100 square inches (254cm2). One  
opening shall be within 12 inches (31cm) of the top and one within 12 inch
(31cm) of the bottom of the enclosure.  
All Air From Outdoors: The confined space shall be provided with two  
permanent openings, one commencing within 12 inches (31cm) of the top and  
one commencing within 12 inches (31cm) from the bottom of the enclosure.  
The openings shall communicate directly, or by ducts, with the outdoors or  
spaces (crawl or attic) that freely communicate with the outdoors.  
1. When directly communicating with the outdoors, each opening shall have a  
minimum free area of 1 square inch per 4000 BTU (2.54cm2/1.2kw) per hour  
of total input rating of all equipment in the eclosure.  
2. When communicating with the outdoothrough vertical ducts, each  
opening shall have a minimum free ea of 1 square inch per 4000 BTU  
(2.54cm2/1.2kw) per hour of total input rating of all equipment in the

WATER CONNECTIONS  
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.  
CAUTION  
If sweat fittings are to be use, DO NOT apply heat to the nipples on top of the  
water heater. Sweat the tubing to the adapter before fittinthe adapter to the  
water connections. It is imperative that heat is not applied to the nipples  
containing a plastic liner.  
WARNIN
FAILURE TO INSTALL AND MAINTAIN NEW, LISTED 3/4” X 3/4”  
TEMPERATURE AND PRESSURE RELIEF VALVE WILL RELEASE THE  
MANUFACTURER FROM ANY CLAIM WHICH MIGHT RESULT FROM  
EXCESSIVE TEMPERATURE AND PRESSURES.  
If this water heater is installea closed water supply system, such as the  
one having a back-flow preventer in the cold water supply, provisions shall be  
made to control thermal expansion. DO NOT operate this water heater in a  
closed system without provisions for controlling thermal expansion. Your water  
supplier or local plumbing inspector should be contacted on how to control this  
situation  
After instalation of the water lines, open the main water supply valve and fill the  
water heater. While the water heater is filling, open several hot water faucets to  
alloair to escape from the water system. When a steady stream of water  
flows through the faucets, close them and check all water connections for  
possible leaks. NEVER OPERATE THE WATER HEATER WITHOUT FIRST  
BEING CERTAIN IT IS FILLED WITH WATER.

WARNING  
For protection against excessive temperatures and pressure, install  
temperature and pressure protective equipment required by local codes, but  
not less than a combination temperature and pressure relief valve certified  
by a nationally recognized testing laboratory that maintains periodic  
inspection of production of listed equipment or materials as meeting the  
requirements of the Standard for Relief Valves and Automatic Gas Shutoff  
Devices for Hot Water Supply Systems, ANSI Z21.22 or the Standard  
CAN1-4.4. Temperature and Pressure and the Standard CAN1-4.4,  
Temperature, Pressure, Temperature and Pressure Relief Valves and  
Vacuum Relief Valves. The combination temperature and pressure relief  
valve shall be marked with a maximum set pressure not to exceed the  
maximum working pressure of the water heater. The combination  
temperature and pressure relief valve shall also have an hourly rated  
temperature steam BTU discharge capacity not less than the hourly rating  
of the water heater.  
Install the combination temperature and pressure relief valve into the opening  
provided and marked for this purpose on the water heater.  
Note: Some models may already be eqped or supplied with a  
combination temperature and pressurelief 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 aboon this page.  
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 NOT thread, plug or cap the discharge line. It is  
rommended 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.  
Do not place a valve between the combination temperature and pressure  
relief valve and the tank.

Installation (Water Connections) continued-  
WARNING  
Hydrogen gas can be produced in an operating water heater that has  
not had water drawn from the tank for a long period of time (generally  
two weeks or more). Hydrogen gas is extremely flammable. To  
prevent the possibility of injury under these conditions, we recommend  
the hot water faucet to be open for several minutes at the kitchen sink  
before you use any electrical appliance which is connected to the hot  
water system. If hydrogen is present, there will be an unusual soun
such as air escaping through the pipes as hot water begins to flow. Do  
not smoke or have open flame near the faucet at the time it is open.  
This water heater can deliver scalding temperature water at any faucet in the  
system. Be careful whenever using hot water to avoid scalding injury. Certain  
appliances such as dishwashers and automatic clothes wahers may require  
increased temperature water. By setting the thermostat on this water heater to  
obtain the increased temperature water required by these appliances, the  
potential for scald injury increases. To protect against injury, you should install  
an ASSE approved mixing valve in the water sytem. This valve will reduce  
point of discharge temperature by mixing cd and hot water in branch supply  
lines. Such valves are available from the manufacturer of this water heater or a  
local plumbing supplier. Please consult ith a plumbing professional.

Figure 2  
DANGER  
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 ASSE approved mixing 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  
pmbing authority should be consulted.  
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.  
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.

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 3). To  
adjust for proper burning, loosen the air shutter nut, rotate shutter to close e  
opening in the burner then slowly rotate the shutter until the yellow tips  
disappear and the flame becomes 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.  
Steel Burner: These models are equipped with self adjusting air mixture and  
do not have an adjustable air shutter (See Figure 4). 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 flae should light smoothly from the  
pilot.

and proper care shall be taken to avoid unnecessary contact (especially by  
children) with the water heater and vent-air intake system. UNDER NO  
CIRCUMSTANCES SHALL FLAMMABLE MATERIALS, SUCH AS  
GASOLINE OR PAINT THINNER BE USED OR STORED IN THE VICINITY  
OF THIS WATER HEATER, VENT-AIR INTAKE SYSTEM OR IN ANY  
LOCATION FROM WHICH FUMES COULD REACH THE WATER HEATER  
OR VENT-AIR INTAKE SYSTEM.  
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 beow. In some installations, the  
maintenance interval may be more frequenepending on the amount of use and  
the operating conditions of the water her. Regular inspection and  
maintenance of the water heater and vent-air intake system will help to insure  
safe and reliable operation.  
1. Annually check the operation of the thermostat.  
2. The flow of combustion anventilation air MUST NOT be restricted. Make  
sure slots in jacket are open and unobstructed. Clear jacket slot openings  
of any dirt, dust, other restrictions. WARNING! The ventilation air system  
may be HOT.  
3. At all times keep the water heater area clear and free from combustible  
materials, gasoline and other flammable vapors and liquids.  
4. Bi-annually conduct a visual check of the main and pilot burner flames to  
determine that they are burning properly. See Burner Flame Check section  
f this installation and operation manual. If sooting or other burner  
anomalies are evident, shut down the water heater by turning off the gas per  
the instructions listed in this manual or as listed on the water heater.  
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, making certain the resettable thermal switch is properly connected  
to the gas control wire leads provided.

WARNING  
·
·
·
Do not operate water heater with jumpered, altered, loosely  
tightened or absent controls and/or components.  
Do not operate water heater with replacement controls and/or  
components which are not exact duplicates or original equipment.  
Thoroughly inspect and replace, (as needed) burner inner door  
gasket and/or sight window gasket any time burner inner door is  
removed or disturbed.  
·
Replace water heater if involved in flammable vapors incident.  
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 prperty damage.  
6. At least once a year, check the combination temperature and pressure relief  
valve to insure that the valve has not become encrusted with lime. Lift the  
lever at the lever at the top of the valve several times until the valve seats  
properly without leaking and operates freely.  
WARNING! THIS WATER Y BE HOT.  
7. Monthly drain off a gallon of water to remove silt and sediment.  
8. 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.  
9. 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.
