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 either
using compressed air or opening main gas
valve located on or near gas meter.
3. Check all joints from gas meter to equip-
ment shutoff valve (see Figure 21). Ap-
ply 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 fireplace with its main gas
valve (control valve) and equipment
shutoff valve from gas supply piping sys-
tem. 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 either
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.

Pressure Testing Fireplace Gas
Connections
1. Open equipment shutoff valve (see Fig-
ure 20).
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 gas control valve (see Figure
21). Apply mixture of liquid 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 14 through 17). Check all
other internal joints for leaks.
7. Turn off fireplace (see To Turn Off Gas
to Appliance, page 15 [Thermostat-con-
trolled models] or page 16 [Manually-
controlled models]).
