The conversion of this appliance from one gas to another must be carried out by an authorized service provider.

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.
