CHECKING GAS CONNECTIONS
WARNING: Test all gas piping
and connections, internal and
external to unit, for leaks after
installing or servicing. Correct
all leaks at once.
WARNING: Never use an open
flame to check for a leak. Apply
a noncorrosive leak detection
fluid to all joints. Bubbles form-
ing show a leak. Correct all leaks
at once.
PRESSURE TESTING GAS SUPPLY
PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG
(3.5 kPa)
1. Disconnect fireplace with its main gas
valve (control valve) and equipment shut-
off valve from gas supply piping system.
Pressures in excess of 1/2 psig will dam-
age fireplace regulator.
2. Cap off open end of gas pipe where equip-
ment shutoff valve was connected.
3. Pressurize supply piping system by either
opening propane/LP supply tank valve
for propane/LP gas or opening main gas
valve located on or near gas meter for
natural gas or using compressed air.
4. Check all joints of gas supply piping sys-
tem. Apply noncorrosive leak detection
fluid to all joints. Bubbles forming show
a leak.
5. Correct all leaks at once.
6. Reconnect fireplace and equipment
shutoff valve to gas supply. Check recon-
nected fittings for leaks.
Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Fig-
ure 21).
2. Pressurize supply piping system by either
opening propane/LP supply tank valve
for propane/LP gas or opening main gas
valve located on or near gas meter for
natural gas or using compressed air.

3. Check all joints from gas meter to equip-
ment shutoff valve for natural gas or pro-
pane/LP supply to equipment shutoff valve
for propane/LP (see Figures 22 and 23).
Apply noncorrosive leak detection fluid to
all joints. Bubbles forming show a leak.
4. Correct all leaks at once.
