IMPORTANT INFORMATION ABOUT THIS WATER HEATER  
This gas water heater was manufactured to voluntary safety standards to reduce the likelihood of a flammable vapor ignition incident.  
The new technology used in meeting these standards makes this product more sensitive to installation errors. Please review the following  
checklist and make any required installation upgrades or changes.

Installation Checklist  
Water Heater Location  
Vent Pipe System  
Check for proper drafting at the water heater draft hood. Refer  
to the “Checking the Draft” section of this manual for the test  
procedure. If the procedure shows insufficient draft is present,  
please check the following.  
Water heater location is important and can affect system  
performance. Please check the following:  
Installation area free of corrosive elements and flammable  
materials.  
Draft hood properly installed.  
Centrally located with the water piping system (For new  
installations). Located as close to the gas piping, vent pipe  
system and 120VAC outlet as possible.  
Vent connectors securely fastened with screws and  
supported properly to maintain six inch clearance.  
Vent connector made of approved material and sized  
correctly.  
Located indoors and in a vertical position. Protected from  
freezing temperatures.  
Vent pipe system installed according to all local and state  
codes or, in the absence of local and state codes, the  
“National Fuel Gas Code”, ANSI Z223.1(NFPA 54)-current  
edition.  
Proper clearances from combustible surfaces  
maintained and not installed directly on a carpeted floor.  
Provisions made to protect the area from water damage.  
Metal drain pan installed and piped to an adequate drain.  
Flue baffle properly positioned in the flue tube.  
Sufficient room to service the water heater. See Clearances  
and Accessibility section of this manual.  
Check the vent system for restrictions/obstructions and  
check the vent termination height. Refer to the “Combustion  
Air and Ventilation” section of this water heater manual for  
specific requirements.  
Water heater not located near an air moving device.  
Is the installed environment dirty (excessive amounts of lint,  
dirt, dust, etc.)? If so, the air intake chamber louvers located  
on the side of the water heater will need to be cleaned  
periodically. Refer to the maintenance section of your water  
heater’s manual for information on cleaning the “Air Intake  
Chamber Screen”.  
Recheck for sufficient combustion air supply.  
Water System Piping  
Temperature and pressure relief valve properly installed with  
a discharge line run to an open drain and protected from  
freezing.  
Combustion Air Supply and Ventilation  
All piping properly installed and free of leaks.  
Heater completely filled with water.  
Check for sufficient combustion air supply. Insufficient air for the  
combustion of gas will result in a inferior burner flame “yellow-  
lazy”, thereby allowing smoking and carbon formation (sooting) to  
build up in the combustion chamber.  
Closed system pressure build-up devices installed.  
Mixing valve (when applicable) installed per manufacturer’s  
instructions (See Water Temperature Regulation section).  
Is the water heater installed in a closet or other small, enclosed  
space? If so:  
Gas Supply and Piping  
Gas type is the same as that listed on the water heater rating  
plate.  
Are there openings for make-up air to enter and exit the  
room/area?  
Gas line equipped with shut-off valve, union, and drip leg.  
Are the openings of sufficient size? Remember, if there are  
other gas-fired or air-consuming appliances in the same  
room, you need more make-up air. Refer to the Location  
Requirements section of this water heater manual for  
specific requirements.  
Use pipe joint compound or teflon tape marked as being  
resistant to the action of petroleum gases.  
Adequate pipe size and approved pipe material.  
An approved noncorrosive leak detection solution used  
to check all connections and fittings for possible gas leaks.  
Correct any leak found.  
Fresh air not taken from areas that contain negative pressure  
producing devices such as exhaust fans, dryers, fireplaces, etc.  
Is there a furnace/air handler in the same room space as  
the water heater? If so, has a return air duct system been  
attached that exits the room? If so, check for leaks on the  
air duct system. If no air duct system is present, correct  
immediately by contacting a local Heating, Ventilation, Air-  
Conditioning & Refrigeration (HVAC-R) authorized service  
provider.  
Electrical Supply  
Water heater to be located as close as possible to a 120VAC  
outlet (extension cord is not allowed).  
Electrical supply installed according to all local and state  
codes or, in the absence of local and state codes, the  
“National Electrical Code”, ANSI/NFPS 70 current edition.  
Fresh air supply free of corrosive elements and  
flammable vapors.  
Ductwork is the same cross-sectional area as the  
openings.

If you have copper piping to the water heater, the two copper  
water pipes can be cut with a hacksaw approximately four  
inches away from where they connect to the water heater.  
See Figure 6. This will avoid cutting off pipes too short.  
Additional cuts can be made later if necessary. Disconnect the  
temperature-pressure relief valve drain line. When the water  
heater is drained, disconnect the hose from the drain valve.  
Close the drain valve. The water heater is now completely  
disconnected and ready to be removed.

shut off valve or water meter.  
Some installations require that  
the water be turned off to the  
entire house. See Figures 2  
and 4.  
FIGURE 6.  
If you have galvanized pipes to the water heater, loosen  
the two galvanized pipes with a pipe wrench at the union in  
each line. Also disconnect the piping remaining to the water  
heater. See Figure 7. These pieces should be saved since  
they may be needed when reconnecting the new water heater.  
Disconnect the temperature-pressure relief valve drain line.  
When the water heater is drained, disconnect the hose from  
the drain valve. Close the drain valve. The water heater  
is now completely disconnected and ready to be removed.  
Mineral buildup or sediment may have accumulated in the  
old water heater. This causes the water heater to be much  
heavier than normal and this residue, if spilled out, could  
cause staining.

Location Requirements  
WARNING  
Carbon Monoxide Poisoning Hazard  
Do not install in a mobile home.  
WARNING  
Fire or Explosion Hazard  
Doing so can result in carbon monoxide poisoning and death.  
• Read instruction manual before installing, using or  
servicing water heater.  
The FVIR System is designed to reduce the risk of flammable  
vapor-related fires. Flammable liquids (such as gasoline,  
solvents, propane, etc,) emit flammable vapors which can be  
ignited by a gas water heater’s hot surface igniter or main burner.  
The resulting flashback and fire can cause death or serious burns  
to anyone in the area.  
• Improper use may result in fire or explosion.  
• Maintain required clearances to combustibles.  
Keep combustibles such as boxes, magazines, clothes, etc. away  
from the water heater area.  
FIGURE 8.  
Site Location  
FV Sensor  
Select a location near the center of the water piping system.  
The water heater must be installed indoors and in a vertical  
position on a level surface. DO NOT install in bathrooms,  
bedrooms, or any occupied room normally kept closed.  
This heater is equipped with a FV sensor for detecting the  
presence of flammable vapors. When the sensor detects those  
vapors, the unit will shut down and not operate. Should this  
happen, please refer to the troubleshooting guide on pages 38-40  
(numbers 9,11,12). Even though this water heater is a flammable  
vapors ignition resistant water heater and is designed to reduce  
the chances of flammable vapors being ignited, gasoline and  
other flammable substances should never be stored or used in  
the same vicinity or area containing a gas water heater or other  
open flame or spark producing appliance.  
Locate the water heater as close to the chimney or gas vent  
as practical. Consider the vent system piping and combus-  
tion air supply requirements when selecting the water heater  
location. The venting system must be able to run from the  
water heater to termination with minimal length and elbows.  
Locate the water heater near the existing gas piping. If  
installing a new gas line, locate the water heater to minimize  
the pipe length and elbows.  
The water heater should be located in an area not subject  
to freezing temperatures. Water heaters located in  
unconditioned spaces (i.e., attics, basements, etc.) may  
require insulation of the water piping and drain piping to  
protect against freezing. The drain and controls must be  
easily accessible for operation and service. Maintain proper  
clearances as specified on the water heater.  
WARNING  
Do not locate the water heater near an air-moving device.  
The operation of air-moving devices such as exhaust fans,  
ventilation systems, clothes dryers, fireplaces, etc., can af-  
fect the proper operation of the water heater. Special atten-  
tion must be given to conditions these devices may create.  
Flow reversal of flue gases may cause an increase of carbon  
monoxide inside of the dwelling (Figure 10).

FIRE AND EXPLOSION HAZARD  
Can result in serious injury or death  
Do not store or use gasoline or other flammable  
vapors and liquids in the vicinity of this or any other  
appliance. Storage of or use of gasoline or other  
flammable vapors or liquids in the vicinity of this or  
any other appliance can result in serious injury or  
death.  
The water heater is to be located as close as possible to  
a 120VAC outlet. NOTE: all electrical wiring should be in  
accordance to the NEC and all local/state electrical codes  
(extension cord is not allowed).  
Read and follow water heater warnings and  
instructions  
NOTE: This water heater must be installed according to all local and  
state codes or, in the absence of local and state codes, the “National  
Fuel Gas Code”, ANSI Z223.1(NFPA 54)-current edition and the  
“National Electrical Code”, ANSI/NFPS 70 current edition.  
Do not use or store flammable products such as gasoline,  
solvents, or adhesives in the same room or area near the

EXHAUST FAN  
IMPORTANT: The water heater should be located in an area where  
leakage of the tank or connections will not result in damage to the  
area adjacent to the water heater or to lower floors of the structure.  
Due to the normal corrosive action of water, the tank will eventually  
leak after an extended period of time. Also any external plumbing  
leak, including those from improper installation, may cause early  
failure of the tank due to corrosion if not repaired. If the homeowner  
is uncomfortable with making the repair a qualified technician should  
be contacted. A suitable metal drain pan should be installed under  
the water heater as shown below, to help protect the property from  
damage which may occur from condensate formation or leaks in  
the piping connections or tank. The pan must limit the water level  
to a maximum depth of 1-3/4” and be two inches wider than the  
heater and piped to an adequate drain. Locate the water heater  
near a suitable indoor drain. Outside drains are subject to freezing  
temperatures which can obstruct the drain line. The piping should be  
at least 3/4” ID and pitched for proper drainage.

Clearances and Accessibility  
NOTE: Minimum clearances from combustible materials are  
stated on the label on the front of the heater adjacent to the gas  
control valve/thermostat of the water heater.  
The water heater is certified for installation on a combustible  
floor.  
IMPORTANT: If installing over carpeting, the carpeting must  
be protected by a metal or wood panel beneath the water  
heater. The protective panel must extend beyond the full  
width and depth of the water heater by at least five inches  
(127mm) in any direction; or if in an alcove or closet installa-  
tion, the entire floor must be covered by the panel.  
Figure 11 may be used as a reference guide to locate the  
specific clearance locations. A minimum of 5 inches of front

Water heater life depends upon water quality, water usage, water  
temperature and the environment in which the water heater is  
installed. Water heaters are sometimes installed in locations  
where leakage may result in property damage, even with the use  
of a metal drain pan piped to a drain. However, unanticipated  
damage can be reduced or prevented by a leak detector or water  
shut-off device used in conjunction with a piped metal drain  
pan. These devices are available from some plumbing supply  
wholesalers and retailers, and detect and react to leakage in  
various ways:

WARNING  
Gas Requirements  
IMPORTANT: Read the rating plate to be sure the water heater  
is made for the type of gas you will be using in your home. This  
information will be found on the rating plate located near the gas  
control valve/thermostat. If the information does not agree with  
the type of gas available, do not install or light. Call your dealer.  
Explosion Hazard  
Gas leaks can not always be detected by smell.  
NOTE: An odorant is added by the gas supplier to the gas used  
by this water heater. This odorant may fade over an extended  
period of time. Do not depend upon this odorant as an indication  
of leaking gas.  
Gas suppliers recommend that you use a gas  
detector approved by UL or CSA.  
For more information, contact your gas supplier.  
Gas Piping  
If a gas leak is detected, follow the “What to do if you  
smell gas” instructions on the cover of this manual.  
The gas piping must be installed according to all local and state  
codes or, in the absence of local and state codes, the “National  
Fuel Gas Code”, ANSI Z223.1(NFPA 54)-current edition.  
Tables 1 and 2 on the following page provide a sizing reference for  
commonly used gas pipe materials. Consult the “National Fuel Gas  
Code” for the recommended gas pipe size of other materials.  
IMPORTANT: The gas supply pressure must not exceed the maximum  
supply pressure as stated on the water heater’s rating plate. The  
minimum supply pressure is for the purpose of input adjustment.  
NOTE: Use pipe joint compound or teflon tape marked as being  
resistant to the action of petroleum gases (See Figure 12.)  
Gas Pressure Testing  
IMPORTANT: This water heater and its gas connection must be leak  
tested before placing the appliance in operation.  
1. Install a readily accessible manual shut-off valve in the gas  
supply line as recommended by the local utility. Know the  
location of this valve and how to turn off the gas to this unit.  
2. Install a drip leg (if not already incorporated as part of  
the water heater) as shown. The drip leg must be no less  
than three inches long for the accumulation of dirt, foreign  
material, and water droplets.  
3. Install a ground joint union between the gas control valve/  
thermostat and the manual shut-off valve. This is to allow  
easy removal of the gas control valve/ thermostat.  
4. Turn the gas supply on and check for leaks. Test all  
connections by brushing on an approved noncorrosive leak-  
detection solution. Bubbles will show a leak. Correct any  
leak found.  
If the code requires the gas lines to be tested at a pressure  
exceeding 14” W.C., the water heater and its manual shut-off  
valve must be disconnected from the gas supply piping system  
and the line capped.  
If the gas lines are to be tested at a pressure less than 14” W.C.,  
the water heater must be isolated from the gas supply piping  
system by closing its manual shut-off valve.  
NOTE: Air may be present in the gas lines and could prevent the  
burner from lighting on initial start-up. The gas lines should be purged  
of air by a qualified technician after installation of the gas piping  
system. While purging the gas piping system of air, insure that the  
fuel is not spilled in the area of the water heater installation, or  
any source of ignition (NOTE: spilled fuel may trip the FV Sensor  
preventing heater from starting). If the fuel is spilled while  
purging the piping system of air follow the “WHAT TO DO IF YOU  
SMELL GAS” instructions on the cover of this manual.

IMPORTANT: Air for combustion and ventilation must not  
come from a corrosive atmosphere. Any failure due to corrosive  
elements in the atmosphere is excluded from warranty coverage.  
IMPORTANT:  
The area must be open and be able to provide the proper air  
requirements to the water heater. Areas that are being used  
for storage or contain large objects may not be suitable for  
water heater installation.  
The following types of installation (not limited to the following)  
will require outdoor air for combustion due to chemical exposure  
and may reduce but not eliminate the presence of corrosive  
chemicals in the air:  
Water heaters installed in open spaces in buildings with un-  
usually tight construction may still require outdoor air to func-  
tion properly. In this situation, outside air openings should be  
sized the same as for a confined space.  
beauty shops  
photo processing labs  
buildings with indoor pools  
water heaters installed in laundry, hobby, or craft rooms  
water heaters installed near chemical storage areas  
Modern home construction usually requires supplying out-  
side air into the water heater area.  
Combustion air must be free of acid-forming chemicals such as  
sulfur, fluorine, and chlorine. These elements are found in aerosol  
sprays, detergents, bleaches, cleaning solvents, air fresheners, paint,  
and varnish removers, refrigerants, and many other commercial and  
household products. When burned, vapors from these products form  
highly corrosive acid compounds. These products should not be  
stored or used near the water heater or air inlet.  
Confined Space  
For the correct and proper operation of this water heater, ample  
air must be supplied for the combustion, ventilation, and dilution  
of flue gases. Small enclosures and confined areas must have  
two permanent openings so that sufficient fresh air can be drawn  
from outside of the enclosure. One opening shall be within 12  
inches of the top and one within 12 inches of the bottom of the  
enclosure as shown in Figure 13.  
Combustion and ventilation air requirements are determined by  
the location of the water heater. The water heater may be located  
in either an open (unconfined) area or in a confined area or small  
enclosure such as a closet or small room. Confined spaces are  
areas with less than 50 cubic feet for each 1,000 BTUH of the total  
input for all gas-using appliances.  
The size of each opening (free area) is determined by the total  
BTUH input of all gas utilization equipment (i.e., water heaters,  
furnaces, clothes dryers, etc.) and the method by which the air  
is provided. The BTUH input can be found on the water heater  
rating plate. Additional air can be provided by two methods:  
Unconfined Space  
A water heater in an unconfined space uses indoor air for  
combustion and requires at least 50 cubic feet for each 1,000  
BTUH of the total input for all gas appliances. The table below  
shows a few examples of the minimum square footage (area)  
required for various BTUH inputs.

12” Max.  
The size of each of the two openings is determined by the  
method in which the air is to be provided. Refer to Table 4 to  
calculate the minimum free area for each opening. Figures 15,  
16, 17 and 18 are typical examples of each method.

Louvers and Grilles  
In calculating free area for ventilation and combustion air supply  
openings, consideration must be given to the blocking effect  
of protection louvers, grilles, and screens. These devices can  
reduce airflow, which in turn may require larger openings to  
achieve the required minimum free area. Screens must not be  
smaller than 1/4” mesh. If the free area through a particular  
design of louver or grille is known, it should be used in calculating  
the specified free area of the opening. If the design and free area  
are not known, it can be assumed that most wood louvers will  
allow 20 - 25% of free area while metal louvers and grilles will  
allow 60 - 75% of free area.  
12” Max.  
FIGURE 13.  
All Air from the Building  
When additional air is to be provided to the confined area  
from additional room(s) within the building, the total volume of  
the room(s) must be of sufficient size to properly provide the  
necessary amount of fresh air to the water heater and other  
gas utilization equipment in the area. If you are unsure that the  
structure meets this requirement, contact your local gas utility  
company or other qualified agency for a safety inspection.  
Each of the two openings shall have a minimum free area of 1  
square inch per 1,000 BTUH of the total input rating of all gas  
utilization equipment in the confined area, but not less than 100  
square inches (Figure 14).  
Louvers and grilles must be locked open or interconnected with  
the equipment so that they are opened automatically during  
equipment operation.  
Keep louvers and grilles clean and free of debris or other  
obstructions.

Vertical gas vents must terminate with a listed cap or other roof  
assembly and be installed according to their manufacturer’s  
instructions.  
The vent connector must be accessible for cleaning,  
inspection, and replacement.  
Vent connectors cannot pass through any ceiling, floor,  
firewall, or fire partition.  
Gas vents must be supported to prevent damage, joint  
separation, and maintain clearances to combustible materials  
(Figures 21 and 22).  
It is recommended (but not mandatory) that a minimum 12  
inches of vertical vent pipe be installed on the draft hood prior  
to any elbow in the vent system.  
IMPORTANT: This gas vent must be terminated in a vertical  
position to facilitate the removal of the burnt gases.  
IMPORTANT: Existing vent systems must be inspected for  
obstructions, corrosion, and proper installation.  
An unused chimney flue or masonry enclosure may be used as a  
passageway for the installation of a gas vent (Figure 22).  
Common (combined) venting is allowable with vertical type B vent  
systems and lined masonry chimneys as long as proper draft for  
the water heater is established under all conditions of operation.  
CAUTION: DO NOT common vent this water heater with any  
power vented appliance.  
Chimney Connection  
IMPORTANT: Before connecting a vent to a chimney, make sure  
the chimney passageway is clear and free of obstructions. The  
chimney must be cleaned if previously used for venting solid  
fuel appliances or fireplaces. Also consult local and state codes  
for proper chimney sizing and application or, in the absence  
of local and state codes, the “National Fuel Gas Code”, ANSI  
Figures 20-22 are examples of vent pipe system installations and  
may or may not be typical for your specific application. Consult  
the “National Fuel Gas Code”, NFPA 54, ANSI Z223.1-current  
edition and the guidelines set forth by prevailing local codes.

As water is heated, it expands (thermal expansion). In a closed  
system, the volume of water will grow. As the volume of water  
grows, there will be a corresponding increase in water pressure  
due to thermal expansion. Thermal expansion can cause  
premature tank failure (leakage). This type of failure is not  
covered under the limited warranty. Thermal expansion can also  
cause intermittent temperature-pressure relief valve operation:  
water discharged from the valve due to excessive pressure build  
up. The temperature-pressure relief valve is not intended for the  
constant relief of thermal expansion. This condition is not covered  
under the limited warranty.

For protection against excessive pressures and temperatures,  
a temperature and pressure relief valve must be installed in the  
opening marked “T & P RELIEF VALVE” (see Figure 25). This  
valve must be design certified by a nationally recognized testing  
laboratory that maintains periodic inspection of the production  
of listed equipment or materials as meeting the requirements  
for Relief Valves for Hot Water Supply Systems, ANSI Z21.22.  
The function of the temperature and pressure relief valve is to  
discharge water in large quantities in the event of excessive  
temperature or pressure developing in the water heater. The  
valve’s relief pressure must not exceed the working pressure of  
the water heater as stated on the rating plate.  
4. Locate the hot water (outlet) & cold water (inlet) pipes to the  
water heater.  
5. Locate the slit running the length of a section of pipe insulation.  
6. Spread the slit open and slip the insulation over the cold  
water (inlet) pipe. Apply gentle pressure along the length of  
the insulation to ensure it is fully seated around the pipe. Also  
ensure that the base of insulation is flush with the water heater.  
Once seated, secure the insulation with duct tape, electrical  
tape, or equivalent.  
7. Repeat steps 5 through 6 for the hot water (outlet) pipe.  
8. Add additional sections of pipe insulation as needed.  
IMPORTANT: Only a new temperature and pressure relief valve  
should be used with your water heater. Do not use an old or  
existing valve as it may be damaged or not adequate for the  
working pressure of the new water heater. Do not place any valve  
between the relief valve and the tank.

should be used at the hot water taps used by these people or  
at the water heater. Mixing valves are available at plumbing  
supply or hardware stores, see Figure 24. Follow manufacturer’s  
instructions for installation of the valves. Before changing the  
factory setting on the thermostat see Table 5 and Figure 32.  
Using the lowest hot water temperature that meets your needs  
will also provide the most energy efficient operation of the water  
heater. Never allow small children to use a hot water tap, or to  
draw their own bath water. Never leave a child or handicapped  
person unattended in a bathtub or shower.  
Burner Flames  
Inspect the burner flames through the viewport and compare  
them to the drawings in Figure 31. A properly operating burner  
should produce a soft blue flame. Blue tips with yellow inner  
cones are satisfactory. The tips of the flame may have a slight  
yellow tint. The flame should not be all yellow or have a sharp  
blue-orange color. Contaminated air may cause an orange  
colored flame. Contact a qualified technician if the flame is not  
satisfactory.  
NOTE: A water temperature range of 120°F-140°F (49°C-60°C)  
is recommended by most dishwasher manufacturers.  
The thermostat of this water heater has been factory set at  
its lowest position. It is adjustable and must be reset to the  
desired temperature setting to reduce the risk of scald injury.  
The electronic control display temperature should be set at  
approximately 120°F (49°C) and this is the preferred starting  
point, see Table 5. Some states have a requirement for a lower  
setting. If you need hotter water, follow directions for temperature  
adjustment, but beware of the warnings in this section.

these instructions:  
Read instruction manual for safe  
temperature setting.  
1. “Unlock” the temperature indicators by holding down both  
“COOLER” and “HOTTER” temperature adjustment buttons  
at the same time for one second (See Figure 32). The dis-  
play will light up. The display will only remain on for 30 sec-  
onds if no further buttons are pressed. After 30 seconds the  
control will go back to “Lock” mode (“Lock” mode indicates  
a temperature setting is locked into the control memory).  
Due to the nature of the typical gas water heater, the water  
temperature in certain situations may vary up to 30°F (16.7 °C)  
higher or lower at the point of use such as, bathtubs, showers,  
sink, etc.  
HOTTER WATER CAN SCALD: Water heaters are intended to  
produce hot water. Water heated to a temperature which will  
satisfy space heating, clothes washing, dish washing, and other  
sanitizing needs can scald and permanently injure you upon  
contact. Some people are more likely to be permanently injured  
by hot water than others. These include the elderly, children, the  
infirm, or physically/mentally handicapped. If anyone using hot  
water in your home fits into one of these groups or if there is a  
local code or state law requiring a certain temperature water at  
the hot water tap, then you must take special precautions. In  
addition to using the lowest possible temperature setting that  
satisfies your hot water needs, a means such as a mixing valve,  
2. Release both of the temperature adjustment buttons.  
A. To decrease the temperature press and release the  
“COOLER” button until the desired setting is reached.  
B. To increase the temperature press and release the  
“HOTTER” button until the desired setting is reached.  
NOTE: Should overheating occur or the gas supply fail to shut  
off, turn off the manual gas control valve to the appliance.  
NOTE: During low demand periods when hot water is not being  
used, a lower thermostat setting will reduce energy losses and

may satisfy your normal hot water needs. If hot water use is  
expected to be more than normal, a higher thermostat setting may  
be required to meet the increased demand. When leaving your  
home for extended periods (vacations, etc.) Set the electronic  
control display temperature “COOLER” button to its lowest  
setting. This will maintain the water at low temperatures with  
minimum energy losses and prevent the tank from freezing during  
cold weather.  
3. Disconnect the electric connection by unplugging the water  
heater from the wall outlet.  
4. Shut off the incoming water supply to the water heater and  
open a nearby hot water faucet to depressurize the water  
tank.  
5. Remove the manifold cover outer door and connect a hose  
to the drain valve and terminate it to adequate drain or to the  
exterior of the building. Open the drain valve and allow at  
least 5 gallons of water from the tank to drain. Close drain  
and remove hose.

SERVICE AND ADJUSTMENT  
Temperature and Pressure Relief Valve  
Draining and Flushing  
Explosion Harzard  
Temperature-pressure relief  
valve must comply with ANSI  
Z21.22-CSA 4.4 and ASME  
code.  
• Properly sized temperature-  
pressure relief valve must be  
installed in opening provided.  
It is recommended that the tank be drained and flushed every 6  
months to remove sediment which may build up during operation.  
The water heater should be drained if being shut down during  
freezing temperatures. To drain the tank, perform the following  
steps:  
• Can result in overheating  
and excessive tank pressure.  
• Can cause serious injury or  
death.  
1. Turn off the gas to the water heater at the manual gas shut-  
off valve and turn off the electrical power to the gas control/  
thermostat valve.  
Manually operate the temperature and pressure relief valve at  
least once a year to make sure it is working properly. To prevent  
water damage, the valve must be properly connected to a  
discharge line which terminates at an adequate drain. Standing  
clear of the outlet (discharged water may be hot), slowly lift  
and release the lever handle on the temperature and pressure  
relief valve to allow the valve to operate freely and return to its  
closed position. See Figure 34. If the valve fails to completely  
reset and continues to release water, immediately shut off the  
electrial power, manual gas control valve and the cold water  
inlet valve and call a qualified technician. Contact Sears Service  
1-800-4-MY-HOME® (www.sears.com).  
2. Open a nearby hot water faucet until the water is not longer  
hot.  
3. Close the cold water inlet valve.  
4. Connect a hose to the drain valve and terminate it to an  
adequate drain or external to the building.  
5. Open the water heater drain valve and allow all the water to  
drain from the tank. Flush the tank with water as needed to  
remove sediment.  
6. Close the drain valve, refill the tank, and restart the heater  
as directed in this manual.  
If the water heater is going to be shut down for an extended  
period, the drain valve should be left open.

TROUBLESHOOTING GUIDE  
Start Up Conditions  
NOTE: Expansion tanks are pre-charged with a 40 psi air  
charge. If the inlet water pressure is higher than 40 psi, the  
expansion tank’s air pressure must be adjusted to match  
that pressure, but must not be higher than 80 psi.  
Thermal Expansion  
As water is heated, it expands (thermal expansion). In a  
closed system, the volume of water will grow. As the volume of  
water grows, there will be a corresponding increase in water  
pressure due to thermal expansion. Thermal expansion can  
cause premature tank failure (leakage). This type of failure is  
not covered under the limited warranty. Thermal expansion  
can also cause intermittent temperature-pressure relief valve  
operation: water discharged from the valve due to excessive  
pressure build up. The temperature-pressure relief valve is  
not intended for the constant relief of thermal expansion. This  
condition is not covered under the limited warranty.  
A properly sized thermal expansion tank should be installed  
on all closed systems to control the harmful effects of thermal  
expansion. Thermal expansion tanks are available from Sears  
stores and through the Sears Service Centers. Contact the  
local plumbing inspector, water supplier and/or the Sears  
Service Center for assistance in controlling these situations.

Draft Hood Operation  
Check draft hood operation by performing a worst case  
depressurization of the building. With all doors and windows  
closed, and with all air handling equipment and exhaust fans  
operating such as furnaces, clothes dryers, range hoods and  
bathroom fans, a match flame should still be drawn into the draft  
hood of the water heater with its burner firing. If the flame is not  
drawn toward the draft hood, shut off water heater and make  
necessary air supply changes to correct.

Condensation  
Operational Conditions  
Whenever the water heater is filled with cold water, some  
condensate will form while the burner is on. A water heater may  
appear to be leaking when in fact the water is condensation. This  
usually happens when:  
“AIR” In Hot Water Faucets  
A new water heater is filled with cold water for the first time.  
Burning gas produces water vapor In water heaters,  
particularly high efficiency models where flue temperatures  
are lower.  
Large amounts of hot water are used in a short time and the  
refill water in the tank is very cold.  
Moisture from the products of combustion condense on the  
cooler tank surfaces and form drops of water which may fall onto  
the burner or other hot surfaces to produce a “sizzling” or “frying”  
noise.  
HYDROGEN GAS: Hydrogen gas can be produced in a hot water  
system that has not been used for a long period of time (generally  
two weeks or more). Hydrogen gas is extremely ammable and  
explosive. To prevent the possibility of injury under these conditions,  
we recommend the hot water faucet, located farthest away, be  
opened for several minutes before any electrical appliances  
which are connected to the hot water system are used (such as a  
dishwasher or washing machine). If hydrogen gas is present, there  
will probably be an unusual sound similar to air escaping through the  
pipe as the hot water faucet is opened. There must be no smoking  
or open ame near the faucet at the time it is open.  
Because of the suddenness and amount of water, condensation  
water may be diagnosed as a “tank leak”. After the water in the  
tank warms up (about 1-2 hours), the condition should disappear.  
Do not assume the water heater is leaking until there has been  
enough time for the water in the tank to warm up.  
An undersized water heater will cause more condensation.  
The water heater must be sized properly to meet the family’s  
demands for hot water including dishwashers, washing machines  
and shower heads.  
Do not remove the anode, leaving the tank unprotected. By  
doing so, all warranty on the water heater tank is voided.  
Excessive condensation may be noticed during the winter and  
early spring months when incoming water temperatures are at  
their lowest.  
Safety Shut-off and Thermal Switch  
Good venting is essential for a gas fired water heater to operate  
properly as well as to carry away products of combustion and  
water vapor.  
This water heater is designed to automatically shut-off in the  
event of the following:  
1. The burner flame is extinguished for any reason.  
2. The water temperature exceeds 195°F (91°C).  
3. Excessive build up of dust on the louvers of the air intake  
chamber. See Maintenance of your Water Heater Section.  
Smoke Odor  
This unit is also equipped with a flammable vapor sensor (FV  
Sensor), designed to shut off the gas supply in the event the  
water heater has been exposed to flammable vapors (e.g.,  
spilled gasoline). NOTE: If the FV-Sense senses the presence of  
ammable vapors a special FV-Sense reset sequence is required  
to be input into the Electronic Control Display in order to restore  
operation of the water heater.  
It is not uncommon to experience a small amount of smoke and  
odor during the initial start-up. This is due to burning off of oil  
from metal parts, and will disappear in a short while.  
A high temperature limit switch or ECO (Energy Cut Off) in the tank  
is used to shut off the unit if the water temperature exceeds 195°F  
(91°C). The ECO is a single-use switch, which, if activated, requires  
complete replacement of the entire gas control valve/thermostat. If  
the ECO should activate, the water heater cannot be used until the  
gas control valve/thermostat is replaced by a qualified technician.

Read this manual first. Then, before checking the water heater,  
make sure the gas supply has been turned “OFF”, and never turn  
the gas “ON” before the tank is completely full of water.  
Never use this water heater unless it is completely filled with  
water. To prevent damage to the tank, the tank must be filled  
with water. Water must flow from the hot water faucet before  
turning “ON” gas to the water heater.  
A. Water at the draft hood is water vapor which has condensed

switch, turn off power to the water  
heater and reconnect tubing to the  
pressure switch. If pressure reading does  
not reach the .22” WC make point, check  
the system and tubing for restrictions  
and cleanliness.  
D. Attach leads of ohmmeter or continuity  
tester to the terminals of the pressure  
switch. Turn on power to the water  
heater and when the air intake fan  
comes on, check for continuity across
