General

Heater should be located so that any water leaks will not cause damage to any adjacent areas or structures.

Gas Supply Connections

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

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. 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 PRESSURED 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 approved for the fuel being used is recommended.
