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:
If inlet gas pressure is out of
allowable range [4.0” w.c. (1.0kPa) – 10.5” w.c. (2.6kPa)]
for Natural Gas, or [8.0” w.c. (2.0kPa) – 13.0” w.c.
(3.2kPa)] for LP gas, a gas pressure regulator must be
installed to maintain the allowable inlet gas pressure.
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.
