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 psi (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. FAIL-
URE TO FOLLOW THIS PROCEDURE MAY DAM-
AGE THE GAS VALVE. OVER PRESSURIZED 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 pipe compound rated for use with natural
and propane gases is recommended. Apply sparingly
only on male pipe ends, leaving the two end threads
bare.
