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 step 3.
