Checking Gas Connections

INSTALLATION
Continued
NOTICE: Most building codes do not permit con-
cealed gas connections. A flexible gas line is pro-
vided to allow accessibility from the fireplace (see
Figure 24). The flexible gas supply line connection to
the equipment shutoff valve should be accessible.
5. Attach the flexible gas line to gas supply (see Figure 24). Check
tightness of flexible gas line attached to gas regulator of fire-
place (see Figure 24).
6. Check all gas connections for leaks. See Checking Gas Con-
nections.
7. Replace log base assembly back into fireplace. Feed flexible gas
line into fireplace base area while replacing log base assembly. Make
sure the entire flexible gas line is in fireplace base area. Reattach
log base assembly to fireplace with screws removed in step 2.

CHECKING GAS CONNECTIONS
WARNING: Test all gas piping and connections,
internal and external tonit, for leaks after installing or
servicing. Correct all leaks at once.
WARNING: Never use an open flame to check for
a leak. Apply a noncorrosive leak detection fluid to
all joints. Bubbles forming show a leak. Correct all
leaks at once.
CAUTION: Make sure external regulator has been
installed between propane/LP supply and fireplace.
See guidelines under Connecting Fireplace to Gas
Supply , page 13.
Pressure Testing gas Supply Piping system
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
1. Disconnect fireplace with its appliance main gas valve (con-
trol valve) and equipment shutoff valve from gas supply pip-
ing system. Pressures in excess of 1/2 psig will damage fire-
place 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 or opening main gas valve
located on or near gas meter for natural gas, or using com-
pressed air.
4. Check all joints of gas supply piping system. Apply noncorrosive
leak detection fluid to all joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Reconnect fireplace and equipment shutoff valve to gas sup-
ply. Check reconnected fittings for leaks.
