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 (3.5 kPa) 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 ei-
ther opening propane/LP supply tank
valve for propane/LP gas fireplace or
opening main gas valve located on or near
gas meter for natural gas fireplace, or
using compressed air.
4. Check all joints of gas supply piping
system. Apply commercial leak test so-
lution to all gas joints. Bubbles forming
show a leak. Correct all leaks at once.
5. Reconnect fireplace and equipment
shutoff valve to gas supply. Check re-
connected fittings for leaks.
CHECKING GAS
CONNECTIONS

all gas joints. Bubbles forming
show a leak. Correct all leaks at
once.
Installation Items Needed
• 5/16" hex socket wrench or nut-driver
