Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1.
Close equipment shutoff valve (see Fig-
ure 20).
2.
Pressurize supply piping system by ei-
ther using compressed air or opening
propane/LP supply tank valve.
3.
Check all joints from propane/LP sup-
ply to equipment shutoff valve (see Fig-
ure 21). Apply mixture of liquid soap
and water to gas joints. Bubbles form-
ing show a leak.
4.
Correct all leaks at once.

Test Pressures In Excess Of 1/2 PSIG
(3.5 kPa)
1.
Disconnect appliance with its appliance
main gas valve (control valve) and
equipment shutoff valve from gas sup-
ply piping system. Pressures in excess
of 1/2 psig will damage fireplace gas
regulator.
2.
Cap off open end of gas pipe where
equipment shutoff valve was con-
nected.
3.
Pressurize supply piping system by ei-
ther using compressed air or opening
propane/LP supply tank valve.
4.
Check all joints of gas supply piping
system. Apply mixture of liquid soap
and water to gas joints. Bubbles form-
ing show a leak.
5.
Correct all leaks at once.
6.
Reconnect fireplace and equipment
shutoff valve to gas supply. Check re-
connected fittings for leaks.
CHECKING GAS
CONNECTIONS
WARNING: Test all gas pip-
ing and connections for leaks
after installing or servicing. Cor-
rect all leaks at once.
WARNING: Never use an open
flame to check for a leak. Apply a
mixture of liquid soap and water
to all joints. Bubbles forming
show a leak. Correct all leaks at
once.

Connections
1.
Open equipment shutoff valve (see Fig-
ure 20).
2.
Open propane/LP supply tank valve.
3.
Make sure control knob of fireplace is
in the OFF position.
4.
Check all joints from equipment shutoff
valve to thermostat gas valve (see Fig-
ure 21). Apply mixture of liquid soap
and water to gas joints. Bubbles form-
ing show a leak.
5.
Correct all leaks at once.
6.
Light fireplace (see Operating Fire-
place, pages 16 and 17). Check all other
internal joints for leaks.
7.
Turn off fireplace (see To Turn Off Gas
