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 fireplace.
2. Using a hammer and screw driver, re-
move knock-out plug from the side of
the pan that corresponds to the gas line
(see Figure 8).

Test Pressures Equal To or Less Than
1/2 PSIG
1. Close manual shutoff valve (see Fig-
ure 7).
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 manual
shutoff valve (see Figure 7). Apply mix-
ture of liquid soap and water to gas joints.
Bubbles forming show a leak.
4. Correct all leaks at once.

Installation and Gas Connection
1. Place the burner pan assembly in the
center of the fireplace floor. Make sure
the front of pan faces forward.
2. Thread the gas supply fitting to the
fireplace gas supply pipe. Use thread
sealant.
3. Install adapter fitting onto the burner
inlet fitting using thread sealant on
male threads of burner inlet fitting
(see Figure 10). Adjust to most con-
venient position.

3. Unscrew burner inlet fitting from
burner manifold (see Figure 9).
4. Place burner manifold in pan with
threaded opening facing open knock-
out plug.
5. Using thread sealant (resistant to the
action of propane/LP gas) on larger
end of fitting, screw the burner inlet
fitting through hole and into burner
manifold. Tighten using a wrench. If
using propane/LP gas, see Propane/LP
Gas Conversion, page 10.
6. Using burner clamp, screw, and nut pro-
vided, assemble clamp to pan (“U” style
burners only). This will hold the burner
manifold in place.
7. If using optional GA9000 kit, go to Op-
tional GA9000 On/Off Safety Valve/Pi-
lot Kit section for installation instruc-
tions. If using optional GA9100 kit,
follow instructions included with kit for
installation and operation.
OPTIONAL GA9000 ON/OFF
SAFETY VALVE/PILOT KIT
ASSEMBLY
For additional convenience and safety, or
for propane/LP conversion, an optional ON/
OFF safety valve/pilot kit is available. See
Accessories, page 20.
WARNING: You must use a
ON/OFF safety valve/pilot kit for
propane/LP conversion.
Natural Gas Installation
1. Thread the gas control valve onto the
burner inlet fitting (see Figure 11). Use
thread sealant on the male threads of
the burner inlet fitting. Hold the burner
inlet fitting with a wrench to prevent
overtightening the connection to the
burner. Make sure the control rod is
facing the front (see Figure 11).

4. Install the gas connector tube to the gas
supply fitting. Carefully shape tube to
attach to adapter fitting. Be careful not
to cause kinks in tube.
