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 fittings for leaks.
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Figure 17).
2. Pressurize supply piping system by either opening propane/LP
supply tank for propane/LP gas or opening main gas valve lo-
cated on or near gas meter or using compressed air.
3. Check all joints from gas meter to equipment shutoff valve for
natural gas (see Figure 18), or propane/LP supply to equipment
shutoff valve for propane/LP (see Figure 19). Apply a noncorro-
sive leak detection fluid to all joints. Bubbles forming show a leak.
4. Correct all leaks at once.

Checking Gas Connections
4. Connect gas supply line to flexible gas line attached to gas
regulator of fireplace insert (see Figure 16). Use sealant on all
male pipe threads.
5. Check all gas connections for leaks. See Checking Gas
Connections.
6. Replace log base assembly back into fireplace insert. Feed flex-
ible gas line into fireplace insert base area while replacing log
base assembly. Make sure the entire flexible gas line is in fire-
place insert base area. Reattach log base assembly to fireplace
insert with screws removed in step 2, page 11.
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 a 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 appliance 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 insert 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 for propane/LP gas or opening main gas valve lo-
cated on or near gas meter or using compressed air.
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 16). The flexible gas supply line connection to
the equipment shutoff valve should be accessible.
