Filling the Water Heater

Never use this water heater unless it is completely full of 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. To fill the water heater with water:

•Close the water heater drain valve by turning the handle to the right (clockwise). The drain valve is on the lower front of the water heater.

•Open the cold water supply valve to the water heater.

NOTE: The cold water supply valve must be left open when the water heater is in use.

•To ensure complete filling of the tank, allow air to exit by opening the nearest hot water faucet. Allow water to run until a constant flow is obtained. This will let air out of the water heater and the piping.

•Check all water piping and connections for leaks. Repair as needed.

GAS SUPPLY

WARNING

Explosion Hazard

•Use a new CSA approved gas supply line.

•Install a shut-off valve.

•Do not connect a natural gas water heater to an L.P. gas supply.

•Do not connect an L.P. gas water heater to a natural gas supply.

•Failure to follow these instructions can result in death, explosion, or carbon monoxide poisoning.

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.

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 Piping

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.

NOTE: Use pipe joint compound or teflon tape marked as being resistant to the action of petroleum [Propane (L.P.)] gases. (See Figure 11.)

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.
