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 holding the burner housing 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 53.

AF4000 Gas Control Valve
The AF4000 electronic control valve is convertible from
natural gas to propane gas by changing the minimum
rate screw in the valve and by rotating a plastic knob
located under a black cap on the top face of the valve.
1. Remove the black cap by pulling the cap straight off.
Note the position of the marker on the top of the rotary
knob. This marker will point to NAT or LP. (Fig. 55)
2. To convert the valve from NG to LP, push in the knob
and rotate 90° (1/4 turn). NOTE: The shaft should
point to LP and the shaft will remain pushed in.
3. Remove the minimum rate screw, using a small screw-
driver, located in the valve next to the motor drive.
(Fig. 55)
4. Replace the minimum rate screw with the new mini-
mum rate screw supplied in the conversion kit. Ensure
the screw is fully installed. Replace plug.
