Fuel Conversion Instructions

The conversion of this appliance from one
gas to another must be carried out by an
authorized service provider.
The procedure for converting from one gas to
another is the same regardless of the initial
gas used. The only variation is in the orifice
sizes and component part numbers. Your
authorized service provider will ensure the
correct parts are used.
1. Disconnect power to the unit and shut off the gas sup-
ply.
2. Remove window frame assembly.
3. Carefully remove the logs & lava rock material.
4. Remove the screws that are holding the burner hous-
ing in place.
5. Remove the burner housing assembly. Depending on
the model of the appliance you may have to loosen
the pilot bracket retaining screw/nut to allow the pilot
and bracket assembly to tilt and give enough clear-
ance to remove the burner housing assembly.
6. For Model 36LDVR ONLY: Remove the rear log sup-
port and relocate the two (2) screws that locate the
rear log as shown in Figure 49.
