INSTALLATION INSTRUCTIONS
Leak Testing
WARNING: Never use an open flame to
test for gas leaks, because death, personal injury,
and/or property damage can result.
The water heater and its gas connections MUST be
leak-tested at normal operating pressures before the
unit is placed in operation. These tests should also
include all factory connections.
Turn on the gas shut-off valve(s) to the water heater.
Use a soapy water solution to test for leaks at all
the connections and fittings. If bubbles are seen,it
indicates a gas leak that must be corrected.
Contact a qualified service technician.
Pressure Testing the Gas Supply
System
CAUTION: Install a gas pressure regulator
in the gas supply line. This regulator should not
exceed the maximum supply pressure. DO NOT use an
industrial-type gas regulator.
The water heater and its manual gas shut-off valve
must be disconnected from the gas supply piping
system whenever the pressure testing will exceed
1/2 psi (14 in. w.c. [3.5 kPa]).
The water heater must be isolated from the gas piping
system whenever the pressure testing will be less than
and/or up to 1/2 psi (14 in. w.c. [3.5 kPa]). Closing the
manual gas shut-off valve will isolate the water heater
from the gas piping system.
