1. Disconnect replace and its individual
equipment shutoff valve from gas supply
piping system. Pressures in excess of 1/2
psig (3.5 kPa) will damage replace gas
regulator.
2. Cap off open end of gas pipe where equip-
ment shutoff valve was connected.
3. Pressurize supply piping system by either
opening propane/LP supply tank valve
for propane/LP gas replace or opening
main gas valve located on or near gas
meter for natural gas replace, or using
compressed air.
4. Check all joints of gas supply piping sys-
tem. Apply noncorrosive leak detection
uid to all joints. Bubbles forming show a
leak. Correct all leaks at once.
5. Reconnect fireplace and equipment
shutoff valve to gas supply. Check recon-
nected ttings for leaks.

1. Close equipment shutoff valve (see Fig-
ure 33).
2. Pressurize supply piping system by either
opening propane/LP supply tank valve
for propane/LP gas replace or opening
main gas valve located on or near gas
meter for natural gas replace, or using
compressed air.
3. Check all joints from propane/LP supply
tank or gas meter to equipment shutoff
valve (see Figure 34 or 35). Apply non-
corrosive leak detection uid 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 33).
2. Open main gas valve located on or near
gas meter for natural gas or open supply
tank valve for propane/LP gas.
3. Make sure control knob of replace is in
the OFF position.
4. Check all joints from equipment shutoff
valve to thermostat gas valve (see Figure
34 or 35). Apply noncorrosive leak detec-
tion uid to all joints. Bubbles forming
show a leak. Correct all leaks at once.
5. Light replace (see Operation, page 27).
Check all other internal joints for leaks.
6. Turn off replace (see To Turn Off Gas to
Appliance, page 27).
