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.
Pressure Testing Gas Supply Piping System
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
1. Disconnect log set and its individual equipment 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 using 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 using compressed
air or opening main gas valve located on or near gas meter.
3. Check all joints from gas meter to equipment shutoff valve
(see Figure 5). Apply noncorrosive leak detection fluid to gas
joints. Bubbles forming show a leak.
4. Correct all leaks at once.

HEARTH KIT ASSEMBLY AND INSTALLATION
Kit Assembly
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
2. Using a hammer and screw driver, remove knockout plug from
3. Unscrew burner inlet fitting from burner manifold (see Figure 7).
4. Place burner manifold in pan with threaded opening facing
5. Using thread sealant (resistant to the action of propane/LP gas)
6. Using burner clamp, screw, and nut provided, assemble clamp
7. If using optional GA9050A kit, go to Optional GA9050A On/
