Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Fig-
ure 19).
2. Pressurize supply piping system by ei-
ther using compressed air or opening
main gas valve located on or near gas
meter.
3. Check all joints from gas meter to
equipment shutoff valve (see Figure
20). Apply mixture of liquid soap and
water to gas joints. Bubbles forming
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 connected.
3. Pressurize supply piping system by ei-
ther using compressed air or opening
main gas valve located on or near gas
meter.
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.
INSTALLATION

Pressure Testing Fireplace Gas
Connections
1. Open equipment shutoff valve (see Fig-
ure 19).
2. Open main gas valve located on or near
gas meter.
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 20). 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
to Appliance, page 17).
