Gas Pressure

WARNING

Explosion Hazard

•Gas leaks can not always be detected by smell.

•Gas suppliers recommend that you use a gas detector approved by UL or CSA.

•For more information, contact your gas supplier.

•If a gas leak is detected, follow the “What to do if you smell gas” instructions on the cover of this manual.

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.

Gas Pressure Testing

IMPORTANT: This water heater and its gas connection must be leak tested before placing the appliance in operation.

•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 pilot 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, ensure that

the fuel is not spilled in the area of the water heater installation, or any source of ignition. 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.

LP Gas Only

WARNING

Explosion Hazard

Have a qualified person make sure L.P. gas pressure does not exceed 13” water column.

Examples of a qualified person include: licensed plumbers, authorized gas company personnel, and authorized service personnel.

Failure to do so can result in death, explosion, or fire.

Liquefied petroleum gas is over 50% heavier than air and in the occurrence of a leak in the system, the gas will settle at floor level. Basements, crawl spaces, closets and areas below ground level will serve as pockets for the accumulation of gas. Before lighting an L.P. gas water heater, smell all around the appliance at floor level. If you smell gas, follow the instructions as given in the warning on the front page.

When your L.P. tank runs out of fuel, turn off the gas at all gas appliances including pilot lights. After the tank is refilled, all appliances must be re-lit according to their manufacturer’s instructions.
