The chart shown above may be used as a guide in determining the proper water temperature for your home.

DANGER: Households with small children, disabled,

or elderly persons may require a 120°F (49°C) or lower gas control (thermostat) setting to prevent contact with “HOT” water.

Maximum water temperatures occur just after the burner has shut off. To find water temperature being delivered, turn on a hot water faucet and place a thermometer in the water stream and read the thermometer.(See page 17 and 18 for more details.)

The temperature of the water in the heater can be regulated by setting the temperature dial on the front of the gas control (thermostat). To comply with safety regulations the gas control (thermostat) was

set at its lowest setting before the water heater was shipped from the factory.

The illustration at the left details the approximate water temperature for each mark on the Gas Control (Thermostat) Temperature Dial.

DANGER: Hotter water increases the potential for

Hot Water SCALDS.

DANGER!

WARNING

READ ALL INSTRUCTIONS BEFORE LIGHTING

LP and Natural gas have an odorant added to aid in detecting a gas leak. Some people may not physically be able to smell or recognize this odorant. If you are unsure or unfamiliar with the smell of LP or natural gas, ask the gas supplier. Other conditions, such as “odorant fade”, which causes the odorant to diminish in intensity, can also hide or camouflage a gas leak.

DANGER!

LIQUEFIED PETROLEUM (LP PROPANE) AND NATURAL GAS MODELS

● Water heaters utilizing LP gas are

different from natural gas models. A natural gas water heater will not function safely on LP gas and vice versa.

● No attempt should ever be made to

convert the water heater from natural gas to LP gas. To avoid possible equipment damage, personal injury or fire, do not connect the water heater to a fuel type not in accordance with the unit data plate. LP for LP units. Natural gas for natural gas units. These units are not certified for any other fuel type.

● LP appliances should not be installed

below grade (for example, in a basement) if such installation is prohibited by federal, state and/or local laws, rules, regulations or customs.

● LP gas must be used with great caution.

It is heavier than air and will collect first in lower areas making it hard to detect at nose level.

● Before attempting to light the water

heater, make sure to look and smell for gas leaks. Use a soapy solution to check all gas fittings and connections. Bubbling at a connection indicates a leak that must be corrected. When smelling to detect a gas leak, be sure to sniff near the floor also.

● Gas detectors are recommended in LP &

natural gas applications and their installation should be in accordance with the detector manufacturer’s recommendations and/or local laws, rules, regulations or customs.

● It is recommended that more than one

method, such as soapy solution, gas detectors, etc., be used to detect leaks in gas applications.

DANGER: If a gas leak is present or

suspected:

● Do not attempt to find the cause yourself.

● Do not

try to light any appliance.

● Do not

touch any electrical switch.

● Do not

use any phone in your building.

● Leave the house immediately and make

sure your family and pets leave also.

● Leave the doors open for ventilation and

contact the gas supplier, a qualified service agency or the fire department.

● Stay away from the house (or building)

until the service call has been made, the leak is corrected and a qualified agency has determined the area to be safe.

Have the installer show you the location of the gas shut-off valve and how to shut it off if necessary. Turn off the manual shut-off valve if the water heater has been subjected to overheating, fire, flood, physical damage or if the gas supply fails to shut off.

● Read this manual entirely before installing

or operating the water heater.

● Use this appliance only for its intended

purpose as described in this Use and Care Manual.

● Be sure your appliance is properly installed

in accordance with local codes and the provided installation instructions.

● Do not attempt to repair or replace any part

of your water heater unless it is specifically recommended in this manual. All other servicing should be referred to a qualified technician.

SAFETY PRECAUTIONS

IMPORTANT SAFETY INFORMATION. READ ALL INSTRUCTIONS BEFORE USING.

WARNING!

For your safety, the information in this manual must be followed to minimize the risk of fire or explosion, electric shock, or to prevent property damage, personal injury, or loss of life.

READ AND FOLLOW THIS SAFETY INFORMATION CAREFULLY.

SAVE THESE INSTRUCTIONS

Installing the water heater.

This water heater must be installed in accordance with these instructions, local codes, utility company requirements, and/or in the absence of local codes, use the latest edition of CAN/CSA B149 - Natural Gas and Propane Installation Code. A copy can be purchased from the Canadian Standards Association, 5060 Spectrum Way, Mississauga, Ontario L4W 5N6.

Location

The water heater should not be located in an area where leakage from the tank or connections will result in damage to the area adjacent to the heater or to lower floors of the structure.

When such areas cannot be avoided it is recommended that a suitable catch pan, adequately drained, must be installed under the water heater.

The pan must not restrict air flow to the combustion air inlet openings (perforation openings) located around the lower perimeter of the water heater.

Catch pan kits are available from the store where the water heater was purchased, or any water heater distributor.

When installed in a closet, DO NOT block or obstruct any of the combustion air inlet openings located around the perimeter of the water heater. A minimum of 1” (2.5 cm) is required between these combustion air inlet openings and any obstruction.

Make certain the floor underneath the water heater is strong enough to sufficiently support the weight of the water heater once it is filled with water.

A gas fired water heater or any other appliance should not be installed in a space where liquids which give off flammable vapours are to be used or stored. Such liquids include gasoline, LP gas (butane or propane), paint or adhesives and their thinners, solvents or removers.

Because of natural air movement in a room or other enclosed space, flammable vapours can be carried some distance from where liquids which give off flammable vapours are to be used or stored. The open flame of the water heater’s pilot or main burner can ignite these vapours and create a shut down condition of the water

heater which will not allow the water heater to ignite until examined by a Qualified Service Technician.

The water heater must be located so it is not subject to physical damage, for example, by moving vehicles, area flooding, etc.

If local codes require the use of a stand kit to raise the water heater 18” (46 cm) above the floor, please contact the store where the water heater was purchased, or any water heater distributor. These kits must comply with local codes.

● The water heater should be installed as

close as practical to the gas vent or chimney.

● Long hot water lines should be insulated

to conserve water and energy.

● The water heater and water lines should

be protected from exposure to freezing temperatures.

● Do not install the water heater in

bathrooms, bedrooms, any occupied rooms normally kept closed, or in unprotected outdoor areas.

● Minimum clearance from combustible

construction:

If the clearances stated on the Instruction/Warning Label, located on the front of the heater differ, install the water heater according to the clearances stated on the label.

● If the water heater is installed in an

alcove or closet, the entire floor must be covered by a wood or metal panel. A minimum of 24” (61 cm) clearance from the front and top should be available for adequate inspection and servicing.

● The water heater may be installed on

combustible floors, but not directly on carpeting. If the water heater must be installed on carpeting, place a metal or wood panel beneath the water heater, extending beyond its full width and depth at least 3” (7.6 cm) in all directions.

The auxiliary catch pan installation MUST conform to local codes.

Installing the water heater.

Combustion and Ventilation Air

Proper operation of the water heater requires air for combustion and ventilation. Provisions for combustion and ventilation air must comply with referenced codes and standards.

NOTICE: If the water heater is installed in an unconfined space within a building of conventional frame, masonry or metal construction, infiltration air is normally adequate for proper combustion and ventilation. If the water heater is installed in a confined space, provisions for combustion and ventilation air must be made.

A confined space is one having a volume of less than 50 cubic feet (1.4 cubic meters) per, 1000 Btuh of the aggregate input of all appliances within that space.

The air must be supplied through two permanent openings of equal area. One is to be located within 12” (30.5 cm) above the floor and the other is to be located within 12” (30.5 cm) from the ceiling.

The minimum net free area of each opening must not be less than one square inch (6.5 sq cm) per 1000 Btuh of the total input rating of all the appliances in the

enclosure, if each opening communicates with other unconfined areas inside the building.

Buildings of unusually tight construction shall have the combustion and ventilation air supplied from outdoors, or a freely ventilated attic or crawl space.

If air is supplied from outdoors, directly or through vertical ducts, there must be two openings located as specified above and each must have a minimum net free area of not less than one square inch (6.5 sq cm) per 4000 Btuh of the total input rating of all the appliances in the enclosure.

If horizontal ducts are used to communicate with the outdoors, each opening must have a minimum net free area of not less than one square inch (6.5 sq cm) per 2000 Btuh of the total input rating of all the appliances in the enclosure. If ducts are used, the minimum dimensions of rectangular air ducts shall not be less than 3” (7.6 cm).

NOTICE: If the duct openings which supply combustion and ventilation air are to be covered with a protective screen or grill, the net free area (openings in the material) of the covering material must be used in determining the size of the openings. Protective screening for the openings MUST NOT be smaller than 1/4” (0.64 cm) mesh to prevent clogging by lint or other debris.

Corrosive Atmospheres

The air in beauty shops, dry cleaning establishments, photo processing labs, and storage areas for liquid and powdered bleaches or swimming pool chemicals often contain such halogenated hydrocarbons.

An air supply containing halogenated hydrocarbons may be safe to breathe, but when it passes through a gas flame corrosive elements are released that will shorten the life of any gas burning appliance.

Propellants from common spray cans or gas leaks from A/C and refrigeration equipment are highly corrosive after passing through a flame.

The water heater warranty is voided when failure of the heater is due to operation in a corrosive atmosphere.

NOTICE: The water heater should not be installed near an air supply containing halogenated hydrocarbons.

Inspect Shipment

Inspect the water heater for possible damage. Check the markings on the rating plate of the water heater to be certain the type of gas supplied corresponds to the water heater requirements.
