Gas Piping

Fire and Explosion Hazard

•Do not use water heater with

any gas other than the gas shown onthe rating plate.

•Excessive pressure to gas control valve can cause serious

injury or death.

•Turn off gas lines during installation.

•Contact qualified installer or service agency

Make sure the gas supplied is the same type listed on the model rating plate. The inlet gas pressure must not exceed 14 inch water column (3.5kPa) for natural and propane gas (L.P.). The minimum inlet gas pressure listed on the rating plate is for the purpose of input adjustment. If the gas control valve is subjected to pressures exceeding 1/2 pound per square inch (3.5kPa), the damage to the gas control valve could result in a fire or explosion from leaking gas.

If the main gas line shut-off serving all gas appliances is used, also turn "OFF" the gas at each appliance. Leave all gas appliances shut "OFF" until the water heater installation is complete.

A gas line of sufficient size must be run to the water heater. Consult the current edition of National Fuel Gas Code ANSI

Z223.1/NFPA 54 and your gas supplier concerning pipe size.

Breathing Hazard - Carbon Monoxide Gas

•High altitude orifice must be installed for operation above 3,300 ft. (1,006 m) or 5,500 ft (1,676 m) for a high altitude models.

•Contact a qualified installer or service agency.

Breathing carbon monoxide can cause brain damage or death. Always read and understand instruction manual.

If a standard model is installed above 3,300 feet (1,006 m) or a high altitude model is installed above 5,500 feet (1,676 m) the input rating should be reduced at the rate of 4 percent for each 1,000 feet (305 m ) above sea level which requires replacement of the burner odfice in accordance with National Fuel Gas Code ANSI Z223.1/NFPA 54. Contact your local Sears Service Center or local gas supplier for further information.

Failure to replace the standard orifice with a high altitude orifice when installed at elevations above 3,300 feet (1,006 m) or above 5,500 feet (1,676 m) for high altitude model) could result in improper and inefficient operation of the appliance, producing carbon monoxide gas in excess of safe limits, which could result in serious injury or death. Contact your local Sears Service Center or local gas supplier for any specific changes which may be required in your area.

Fire and Explosion Hazard

•Use joint compound or tape compatible with propane

•Leak test before operating heater

•Disconnect gas piping and shut-off valve before pressure testing system.

There must be:

•A readily accessible manual shut off valve in the gas supply line serving the water heater, and

•A ddp leg (sediment trap) ahead of the gas control valve to help prevent dirt and foreign materials from entering the gas control valve.

•A flexible gas connector or a ground joint union between the shut off valve and control valve to permit servicing of the unit.

Be sure to check all the gas piping for leaks before lighting the water heater. Use a soapy water solution, not a match or open flame. Rinse off soapy solution and wipe dry.

The minimum inlet gas pressure shown on the rating plate is that which will permit firing at the rated input.

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

The appliance and its gas connection must be leak tested before placing the appliance in operation.

The appliance and its individual shut-off valve shall be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 pound per square inch (3.5 kPa). It shall be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 pound per square inch (3.5 kPa).

Connecting the gas piping to the gas control valve of the water heater can be accomplished by either of the two methods shown in Figures 19 and 20.
