pRESSURE TESTING GAS SUppLY
pIpING SYSTEM
Test pressures In Excess Of 1/2 pSIG
(3.5 kPa)
1. Disconnect fireplace and its individual equip-
ment 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 connected.
3. Pressurize supply piping system by either
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 noncorrosive leak detection fluid to all
joints. Bubbles forming show a leak. Correct
all leaks at once.
5. Reconnect fireplace and equipment shutoff
valve to gas supply. Check reconnected fittings
for leaks.
Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Figure 34).
2. Pressurize supply piping system by either
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.
3. Check all joints from propane/LP supply tank
or gas meter to equipment shutoff valve (see
Figure 35 for propane/LP or Figure 36 for
natural gas). Apply noncorrosive leak detec-
tion fluid to all joints. Bubbles forming show
a leak. Correct all leaks at once.
