4. Connect gas supply line to flexible gas line attached to gas
regulator of fireplace insert (see Figure 20). Use sealant on all
male pipe threads.
5. Check all gas connections for leaks. See Checking Gas Con-
nections.
6. Replace log base assembly back into fireplace insert. Feed flexible
gas line into fireplace insert base area while replacing log base as-
sembly. Make sure the entire flexible gas line is in fireplace insert
base area. Reattach log base assembly to fireplace insert with screws
removed in step 2.

NOTICE: Most building codes do not permit con-
cealed gas connections. A flexible gas line is pro-
vided to allow connection with the fireplace (see
Figure 20). The flexible gas supply line connection to
the equipment shutoff valve should be accessible.

Pressure Testing Gas Supply Piping System
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
1. Disconnect appliance from 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 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 a non-
corrosive 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 21).
2. 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.
CHECKING GAS CONNECTIONS
WARNING: Test all gas piping and connections
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.
