CHECKING GAS CONNECTIONS
WARNING: Test all gas pip-
ing and connections, internal
and external to unit, 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 noncorrosive leak de-
tection fluid to all joints. Bubbles
forming show a leak. Correct all
leaks at once.
PRESSURE TESTING GAS SUPPLY
PIPING SYSTEM
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 supply piping system.
Pressures in excess of 1/2 psig will damage
fireplace insert gas regulator.
2. Cap off open end of gas pipe where equip-
ment shutoff valve was connected.
3. Pressurize supply piping system by either open-
ing propane/LP supply tank for propane/LP gas
or opening main gas valve located on or near
gas meter or using compressed air.
4. Check all joints of gas supply piping system.
Apply a noncorrosive leak detection fluid to
all joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Reconnect fireplace insert and equipment
shutoff valve to gas supply. Check reconnected
