Leak Testing

Always leak test ﬁnal gas assembly for gas leaks according to the procedures outlined in NFPA 54 and

all local codes and/or Standards.

For leak testing on pressures below ½” PSI

Before leak testing, close the ﬁeld installed manual shut off valve shown on Figure 3.1 on the supply

line to isolate the gas valve from the pressure.

NOTE: All factory installed gas connections have passed an approved leak test.

For leak testing on pressures above ½” PSI

When leak testing with pressures above ½” PSI (14 inches W.C.), the unit must be isolated from the

supply pipe. Close the ﬁeld installed manual shut off valve, disconnect the supply line to the unit, and

temporarily cap the supply line for testing purposes.

WARNING

Use a soap solution or equivalent for leak testing. Never test for leak with an open

ﬂame. Failure to comply could result in personal injury, property damage or death.
