flame to check for a leak. Apply a
mixture of liquid soap and water
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 (control valve) and equip-
ment shutoff valve from gas supply pip-
ing system. Pressures in excess of 1/2 psig
will damage fireplace insert gas regulator.
2.
Cap off open end of gas pipe where
equipment shutoff valve was connected.
3.
Pressurize supply piping system by either
using compressed air or opening main gas
valve located on or near gas meter.

2.
Pressurize supply piping system by either
using compressed air or opening main gas
valve located on or near gas meter.

Route gas supply line through access
opening of fireplace insert (see Figure
2, page 3).
4.
Connect gas supply line to flexible gas
line attached to gas regulator of fire-
place insert (see Figure 19). Use seal-
ant on all male pipe threads.
5.
Check all gas connections for leaks. See
Checking Gas Connections.
6.
Replace log base assembly back into fire-
place insert. Feed flexible gas line into fire-
place insert base area while replacing log
base assembly. Make sure the entire flex-
ible gas line is in fireplace insert base area.
Reattach log base assembly to fireplace
insert with screws removed in step 2.

Remove screws that attach log base assem-
bly to fireplace insert (see Figure 18). Care-
fully lift up log base assembly and remove
