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 detec-
tion 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 log set and its individual equip-
ment shutoff valve from gas supply piping
system.
2. Cap off open end of gas pipe where equip-
ment 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.
4. Check all joints of gas supply piping sys-
tem. Apply a noncorrosive leak detection
fluid to all joints. Bubbles forming show a
leak.
5. Correct all leaks at once.
6. Reconnect log set 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 5).
2. Pressurize supply piping system by either
using compressed air or opening main gas
valve located on or near gas meter.
3. Check all joints from gas meter to equip-
ment shutoff valve (see Figure 6). Apply
a noncorrosive leak detection fluid to all
joints. Bubbles forming show a leak.
4. Correct all leaks at once.

Note: The following instructions apply to
both standard single bar burners, as well as
dual flame “U” style burners. Be sure all pipe
threaded connections are tight, and have
thread compound to prevent leaks.
1. Determine which side the gas line will be
coming into the fireplace.
2. Using a hammer and screw driver, remove
knock-out plug from the side of the pan
that corresponds to the gas line (see
Figure 7).
3. Unscrew burner inlet fitting from burner
manifold (see Figure 8, page 9).
4. Place burner manifold in pan with thread-
ed opening facing open knock-out plug.
