Propane/LP Gas Conversion
To convert to propane/LP gas, the regulator pressure must be reset.
Also, the burner inlet fitting and pilot orifice must be replaced. The
propane/LP burner inlet fitting is supplied with the orifice installed for
your log set.
Burner Inlet Fitting
1. Remove the pilot assembly from the valve cover by removing
the two screws on the bracket (see Figure 7).
2. Unscrew and remove piezo ignitor and ignitor cover from
valve cover.
3. Remove the two (2) screws on the burner pan and the remaining
screw on the rear of the control valve to remove valve cover.
4. Unthread control valve and burner inlet fitting from burner tube
by turning valve counter-clockwise (see Figure 8) .
5. Remove natural gas inlet fitting from the control valve and
discard (see Figure 8). DO NOT remove the orifice from this
fitting. The propane/LP burner inlet fitting is included in the
hardware kit (see Figure 11, page 8).

6. Be sure to use the correct orifice for your appliance. The orifice
kit included with this appliance contains an orifice installed in
an air mixer fitting.
7. Using thread sealant (resistant to the action of propane/LP gas)
on smaller end of fitting, screw the burner inlet fitting into the
outlet side of the gas control. Tighten using a wrench.
8 . Rethread the valve and fitting assembly into the burner tube
until fully threaded and level with the burner pan. Reattach the
valve cover with the three (3) screws previously removed in
