3. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas or opening main gas valve lo-
cated on or near gas meter for natural gas, or
using compressed air.
4. Check all joints of gas supply piping system.
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 reconnected fit-
tings for leaks.
Test Pressures Equal To or Less Than 1/2
PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Figure 24).
2. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas or opening main gas valve lo-
cated on or near gas meter for natural gas, or
using compressed air.
3. Check all joints from gas meter to equipment
shutoff valve for natural gas or propane/LP
supply to equipment shutoff valve for pro-
pane/LP (see Figures 25 or 26). Apply non-
corrosive leak detection fluid to all joints.
Bubbles forming show a leak.
4. Correct all leaks at once.

1. Open equipment shutoff valve (see Figure 24).
2. Open main gas valve located on or near gas
meter for natural gas or open propane/LP sup-
ply tank valve.
3. Make sure control knob of fireplace is in the
OFF position.
4. Check all joints from equipment shutoff valve
to gas regulator (Thermostat-Controlled Mod-
els), or to gas control valve (Remote-Ready
Models) (see Figures 25 or 26). Apply non-
corrosive leak detection fluid to all joints.
Bubbles forming show a leak.
5. Correct all leaks at once.
6. Light fireplace (see Operating Fireplace,
page 23). Check all other internal joints for
leaks.
7. Turn off fireplace (see To Turn Off Gas to Ap-
pliance, page 25 for Thermostat-Controlled
Models or page 27 for Remote-Ready Models).
