GAS SUPPLY CONNECTIONS

Gas piping must have a sediment trap ahead of the heater gas controls, and a manual shut-off valve located outside the heater jacket. All gas piping should be tested after installation in accordance with local codes.

Manual Shut Off Valve

Sediment Trap

Fig. # 8156

CAUTION: The heater and its manual shut off valve must be disconnected from the gas supply during any pressure testing of that system at test pressures in excess of 1/2 psig (3.45 KPA). Dissipate test pressure in the gas supply line before reconnecting the heater and its manual shut off valve to gas supply line.

FAILURE TO FOLLOW THIS PROCEDURE MAY DAMAGE THE GAS VALVE. OVER PRES- SURED GAS VALVES ARE NOT COVERED BY WARRANTY. The heater and its gas connections shall be leak tested before placing the appliance in operation. Use soapy water for leak test. Do NOT use open flame.

NOTE: Do not use teflon tape on gas line pipe thread. A flexible sealant is recommended.

A minimum of 7" W.C. and a maximum of 14" W.C. upstream pressure under load, and no load conditions must be provided for natural gas or a minimum of 12" W. C. and a maximum of 14" for propane gas.

GAS PRESSURE REGULATOR

The gas pressure regulator is preset and sealed at 4" W.C. for natural gas, and ll" W. C. for propane gas. Between the gas valve and the burners is a l/8" pipe plug. The pressure at this point, taken with a manome- ter, should be about 3.7" W. C. natural gas and l0.5" W.C. propane gas. If an adjustment is needed, remove

seal and turn adjustment screw clockwise
