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. Retighten all ttings.
5. If leaks still exist, turn off gas supply and
call a qualied service person.
6. Reconnect fireplace and equipment
shutoff valve to gas supply. Check recon-
nected ttings for leaks.

1. Close equipment shutoff valve (see Fig-
ure 53).
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 54 or Figure 55). Ap-
ply noncorrosive leak detection uid to
all joints. Bubbles forming show a leak.
Retighten all ttings
4. If leaks still exist, turn off gas supply and
call a qualied service person.
