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 with its individual equip-
ment shutoff valve from gas supply piping
system.
2. Cap off open end of gas pipe where equipment
shutoff valve was connected.
3. Pressurize supply piping system by either us-
ing compressed air or opening main gas valve
located on or near gas meter.
4. Check all joints of gas supply piping system.
Apply noncorrosive leak detection fluid to gas
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 us-
ing 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
noncorrosive leak detection fluid to all joints.
Bubbles forming show a leak.
4. Correct all leaks at once.

HEARTH KIT ASSEMBLY AND
INSTALLATION
1. Determine which side the gas line will be
coming into the fireplace.
NOTICE: Unit comes preassembled with gas
inlet on right side. If your fireplace gas supply
is on the left, gas inlet should be repositioned
to left side of unit.
2. If gas supply line in your fireplace is on the right
side, continue to step 3. If not, see Reposition-
ing the Gas Inlet to the Left Side of Unit.
3. Install adapter fitting that comes with log set
into fireplace gas supply pipe (see Figure 7).
Seal using thread sealant.
