OPTIONAL GA9003 SERIES
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 17.
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
close pipe nipple (see Figure 11). Use
thread sealant on the male threads of
the fitting. Thread other end of the
nipple into the burner manifold block.
Hold the manifold block with a wrench
to prevent stressing the connections to
the burners. Make sure the control rod
is facing the front (see Figure 11).
2. Attach the pilot gas line to the pilot out-
let of the gas control valve and tighten.
Connect the thermocouple to the rear of
the gas control valve (see Figure 12). Do
not overtighten (finger-tight plus 1/4
turn). If using propane/LP gas, see
Changing Pilot Orifice, page 11.
3. Install the inlet fitting into the inlet
opening of the gas control valve (see
Figure 13). Use thread sealant on the
male pipe threads.
4. Thread the gas supply fitting to the fire-
place gas supply pipe (see Figure 10, page
9). Adjust to most convenient position.
5. Install the gas flex line to the gas supply
fitting. Carefully shape tube to attach to
adapter fitting.
6. Place the burner pan assembly in the
center of the fireplace floor. Make sure
the front of pan faces forward.
7. Test for leaks following instructions
under Testing Burner for Leaks, page 11.
8. Retighten and adjust the location of the
gas control as necessary. The gas con-
trol should be level, with the control
rod to the front.

9. Install valve cover to burner pan using
screws provided.
10. Install thermocouple, pilot, and ignitor
onto valve cover as shown in Figure 14.
Use the provided screws.
11. Push the control rod extension onto the
“D” shaped control rod through the cen-
ter hole in the cover.
12. Install the position decal and control
knob making sure to align the marks
with the correct stop positions of the
gas control. Pilot position will allow the
knob to push in about 1/2". Align the
decals in the pilot position.

Propane/LP Gas Conversion
To convert to propane/LP gas, the two main
burner orifices and pilot orifice must be
replaced.
Main Burner Orifices
Note: Be sure all pipe threaded connections
are tight, and have thread compound to
prevent leaks. Be sure to use the correct
orifice for your unit. See chart on page 7.
1. Remove the burner inlet fitting from
the front burner manifold (installed in
burner pan). See Figure 15, page 11.
2. Make sure ports on front burner mani-
fold are facing the front (open side) of
burner pan. Refit if needed.
3. Replace front burner injector with the
provided injector. See chart on page 7
and Figure 16, page 11. Using thread
sealant (resistant to the action of pro-
pane/LP gas) on larger end of fitting,
screw the burner inlet fitting through
the hole and into the burner manifold.
Tighten using a 7/8" wrench.
