PLUMBING
Fig. # 8090.1
GENERAL
Heater should be located so that any water leaks
will not cause damage to any adjacent areas or struc-
tures.
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.
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. 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 is recommended.
