Propane/LP Gas Conversion
To convert to propane/LP gas, the regulator
pressure must be reset. Also, 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 pilot assembly from valve cover
by removing two screws on bracket (see
Figure 7).
2. Unscrew and remove piezo ignitor and
ignitor cover from valve cover.
3. Remove two (2) screws on burner pan
and remaining screw on rear of the control
valve to remove valve cover.
4. Unthread control valve and burner inlet
fitting from burner tube by turning valve

appliance. The orifice kit included with this
appliance contains an orifice installed in
an air mixer fitting.
