CHECKING GAS CONNECTIONS
WARNING: Test all gas piping
and connections , internal and
external to unit, for leaks after
installing or servicing. Correct
all leaks at once.
WARNING: Never use an open
flame to check for a leak. Apply
noncorrosive leak detection 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 fireplace and its individual
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 equip-
ment 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 sys-
tem. Apply noncorrosive leak detection
fluid to all joints. Bubbles forming show a
leak. Correct all leaks at once.

nected fittings for leaks.
Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
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 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
