THIS MANUAL HAS BEEN PREPARED TO ACQUALNT YOU WITH THE INSTALLATION, OPERATION AND
MAINTENANCE OF YOUR GAS WATER HEATER AND TO PROVIDE IMPORTANT SAFETY INFORMATION.
WE URGE YOU TO READ ALL INSTRUCTIONS THOROUGHLY BEFORE ATTEMPTING INSTALLATION OR
OPERATION OF YOUR WATER HEATER. KEEP THESE INSTRUCTIONS FOR FUTURE REFERENCE.

The manufacturer of this water heater will not be liable for any damages caused by failure to comply with the installation and operating instructions
outlined on the following pages. These instructions are a guide for the correct installation of your water heater. lf you lack the necessary skills
required or have difficulty following the directions, you should not proceed but get help from a qualified person for that part of the installation you
do not understand. Your gas-fired water heater is design-certified by ETL. The installation should conform with the local code or the authority

having jurisdiction, or in the absence of such, the National Gas Code. ANSI Z223.1 NFPA 54. A copy of the Code can be purchased from American
Gas Association Order Processing, 400 N. Capital St. N.W. Washington D.C. 20001 e-mail ordering: www.aga.org Fax ordering: 866-8 I6-9444.
A rating plate identifying your water heater will be found next to the gas control valve (thermostat).

The water utility supply meter may contain a check valve, back flow preventer or water pressure reducing valve. This will create a closed water

system. During the heating cycle of the water heater, the water expands creating a pressure build up in the water system. A temperature and
pressure relief valve must be installed on the water heater (150 PSI maximum pressure setting. See Temperature and Pressure Relief Valve). To

prevent the temperature and pressure relief valve from discharging hot water, loss of energy, and reduce the possible build-ip of lime on the
temperature and pressure relief valve seat.

If the water supply system contains a check valve, back flow preventer or water pressure reducing valve you will have closed
water system and the pressure will build up during the water heating cycle. The temperature and pressure relief valve on the
water heater will leak during the water heating cycle resulting in loss of energy. To prevent the build up of lime in the T&P valve
and damage to the water heater by pressure surges you must install an expansion tank on the cold water supply line. The thermal
expansion tank should have a minimum capacity of 4.5 U.S. gallons. It requires both T&P valves and expansion tanks for closed
system.

Multiple water heating system and/or a system with additional storage tank must be sized by thermal expansion tank
manufacturer.

certain it corresponds with your application.

Read these instructions thoroughly before proceeding with the installation of this new gas-fired water heater. If there is any difficulty understanding
all or any part of these instructions, it is recommended that a qualified service person perform the installation.

NOTICE: The manufacturer's warranty does not cover damage or injury cause by the use of any energy-saving devices (other than those authorized

by the manufacturer) in conjunction with this water heater. The use of unauthorized energy-saving devices may decrease the life of the water heater
and endanger life and/or property. The manufacturer will not be held liable for loss or injury resulting from the use of any unauthorized device in
conjunction with this water heater.

This water heater has been equipped for use with one type of gas only. Compare the information provided on the rating plate affixed to the front

of the water heater, making sure that the gas stated on the rating plate is the same as the gas to be used. DO NOT ATTEMPT TO USE THIS
WATER HEATER WITH ANY GAS OTHER THAN THE TYPE LISTED ON THE RATING PLATE. Do not attempt to convert this water heater

for use with a gas other than the type for which it is equipped. Failure to use the proper gas can create an unsafe condition resulting in property

damage, bodily injury or death. Consult local gas supplier or gas company if there are any questions.

For installations in high altitude regions, this water heater must be ordered from the supplier to the manufacturer's specifications for that particular

altitude. Contact the company listed on the rating label when ordering high altitude constructed water heaters.

For any questions not covered in this booklet, contact your dealer or write to us at the address shown the rating plate affixed to the front of the

water heater.

This water heater has been designed and manufactured for the express purpose of heating and storing potable water and space heating. See page

23 for space heating instructions. Any use other than this purpose will release the manufacturer from any liability or warranty claims stemming from
the issue of this product. Consult local authorities.

INSTALLATION

Location- Select a location accessible to water lines, gas supply (type identified on the rating plate), an adequate open drain, and as close as practi-

cal to a chimney or gas vent. When installed, the water heater must be level. To prevent excessive heat loss through water piping, locate the water

heater as close as practical to the areas of greatest hot water usage. Do not locate the water heater where lines could be subjected to freezing
temperatures.

Adequate clearances shall be provided for easy access to controls by service personnel to enable proper cleaning, servicing and operation of the
water heater. Under no circumstances is the front of the water heater to be placed in a position where the burner tray assembly cannot slide out
for removal when servicing.

DO NOT STORE OR USE FLAMMABLE LIQUIDS, VAPORS, OR MATERIALS IN THE VICINITY OF THIS OR ANY OTHER APPLIANCE.

CAUTION

IMPORTANT

BEFORE PROCEEDING WITH THE INSTALLATION OF THIS WATER HEATER, READ AND THOROUGHLY UNDERSTAND THESE
INSTALLATION AND OPERATION INSTRUCTIONS. IF THERE ARE ANY QUESTIONS, THIS INSTALLATION SHOULD BE PERFORMED
BY A QUALIFIED SERVICE PERSON.

CAUTION

Combustion and Ventilation Air- Provisions must be made for adequate combustion and ventilation air. Details outlining proper air supply

for various types of installation are prescribed by the National Fuel Gas Code (ANSI Z-223.1/ NFPA 54) latest edition. If the water heater is installed

in unconfined space within the building, infiltration air may be adequate for proper combustion and ventilation. Buildings of tight construction
(weather stripping, caulked, etc.) require additional air from outdoors.

If the water heater is installed in a confined space (volume is less than 50 cu. ft. per I000 BTUH of the total input rating of all gas appliances in that
space), air must be supplied through two permanent openings. One opening shall be within 12 inches from the top of the enclosure and one within
12 inches of the bottom. The openings must be protected by metal louvers or 1/4" min. mesh metal screen.
The size of the openings are as follows:

1.- lf the openings communicate directly with an additional room(s) of sufficient volume, each opening shall have a minimum free area opening of 1
sq. in. per 1000 BTUH of the total input rating of all gas appliances in the confined space, but not less than 100 sq. inches.

2.- If the openings communicate directly with the outdoors or through vertical ducts with the outdoors, each opening shall have a minimum free
area of I sq. in. per 4000 of the total rating of all gas appliances in the enclosure.

3.- If the openings communicate with the outdoors through horizontal ducts, each opening shall have a minimum free area of 1 sq. in. per 2000 BTUH
of the total rating of all gas appliances.

The draft diverter relief opening of the water heater and the combustion air inlet must be in the same atmospheric
pressure zone. Large exhaust fans in kitchens or other locations can lower the air pressure inside an enclosure and
interfere with proper operation and venting of the water heater. In these cases, the water heater should be installed
in a separate room with combustion and ventilation air supplied directly from outdoors as previously described.

Corrosive Atmosphere- Water heater corrosion and component failure can be caused by the heating and breakdown of airborne chemical

vapors. Spray can propellants, cleaning solvents, refrigeration and air conditioning refrigerants, swimming pool chemicals, calcium and sodium

chloride, waxes, and process chemicals are typical compounds which are potentially corrosive. These materials are corrosive at very low

concentration levels with little or no odor to reveal their presence.

Products of this sort must not be stored near the water heater, nor should air which is brought in contact with the water heater contain any of these

chemicals. Flammable vapors may be drawn by air currents from other areas of the structure to this appliance. If necessary, uncontaminated air

should be obtained from remote or outside sources.

THE WARRANTY ON THIS WATER HEATER DOES NOT COVER DAMAGE CAUSED FROM OPERATION IN A CORROSIVE

ATMOSPHERE.

Water Damage/Drain Pan- 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. WHEN SUCH
LOCATIONS CANNOT BE AVOIDED, A SUITABLE DRAIN PAN MUST BE INSTALLED UNDER THE WATER
HEATER HAVING A LENGTH AND WIDTH AT LEAST 3 INCHES GREATER THAN THE DIAMETER OF THE
WATER HEATER, A MAXIMUM HEIGHT OF 1-3/4 INCHES, AND BE PIPED TO AN OPEN DRAIN. DO NOT
RESTRICT THE FLOW OF COMBUSTION AIR.
