Test Pressures In Excess Of 1/2 PSIG
(3.5 kPa)
1. Disconnect appliance with its appli-
ance main gas valve (control valve)
and equipment shutoff valve from gas
supply piping system. Pressures in ex-
cess of 1/2 psig will damage fireplace
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 heater 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.
CAUTION: Make sure external
regulator has been installed be-
tween propane/LP supply and fire-
place. See guidelines under
Con-
necting to Gas Supply, page 12.
Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see
Figure 23).
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 tank to equipment shutoff valve (see
Figure 24). Apply mixture of liquid
soap and water to gas joints. Bubbles
forming show a leak.
4. Correct all leaks at once.
Pressure Testing Fireplace Gas
Connections
1. Open equipment shutoff valve (see
Figure 23).
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 22, page 13). Apply mixture of liq-
uid soap and water to gas joints.
Bubbles forming show a leak.
5. Correct all leaks at once.
6. Light fireplace (see Operating Fire-
place, pages 16 through 18). Check all
other internal joints for leaks.
7. Turn off fireplace (see To Turn Off Gas
to Appliance, page 17).
8. Replace front panel.
