Pressure Testing Gas Supply Piping System
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
1. Disconnect fireplace and its individual equipment shutoff valve
from gas supply piping system. Pressures in excess of 1/2 psig
(3.5 kPa) will damage fireplace gas regulator.
2. Cap off open end of gas pipe where equipment shutoff valve
was connected.
3. Pressurize supply piping system by either opening propane/LP
supply tank valve for propane/LP gas fireplace or opening main
gas valve located on or near gas meter for natural gas fire-
place, or using compressed air.
CHECKING GAS CONNECTIONS
WARNING: Test all gas piping and connections
for leaks after installing or servicing. Correct all leaks
at once.
WARNING: Never use an open flame to check for a
leak. Apply noncorrosive leak detection fluid to all joints.
Bubbles forming show a leak. Correct all leaks at once.

4. Check all joints of gas supply piping system. Apply noncorro-
sive leak detection fluid to all joints. Bubbles forming show a
leak. Correct all leaks at once.
5. Reconnect fireplace and equipment shutoff valve to gas sup-
ply. Check reconnected fittings for leaks.
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Figure 33).
2. Pressurize supply piping system by either opening propane/LP
supply tank valve for propane/LP gas fireplace or opening main
gas valve located on or near gas meter for natural gas fire-
place, or using compressed air.
3. Check all joints from propane/LP supply tank or gas meter to
equipment shutoff valve (see Figure 34 for propane/LP or Figure
35 for natural gas). Apply noncorrosive leak detection fluid to all
joints. Bubbles forming show a leak. Correct all leaks at once.
