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.

Using a suitable wrench on the hexagonal body un- screw the pilot hood assembly from the pilot, do not twist the hood itself. Remove the orifice and replace it with the new orifice supplied in the kit. Refit the pilot hood assembly. Do not over-tighten the pilot hood. The hood must return to its original alignment. Take care not to damage the thermocouple, thermo- pile or igniter.
