	NOTICE
	State or local codes may only allow operation of this appliance in a
	vented configuration. Check your state or local codes.
	WARNING
	Before installing in a solid fuel burning fireplace, the chimney flue
	and firebox must be cleaned of soot, creosote, ashes and loose paint
	by a qualified chimney cleaner. Creosote will ignite if highly heated.
	Inspect chimney flue for damage. If damaged, operate heater with
	flue damper closed.
	WARNING
	Seal any fresh air vents or ash clean-out doors located on floor or wall
	of fireplace. If not, drafting may cause pilot outage or sooting. Use a
	heat-resistant sealant. Do not seal chimney flue damper.
	WARNING

	• in a bedroom or bathroom
	• in a recreational vehicle
	• where curtains, furniture, clothing, or other flammable objects are
	less than 36 inches from the front, top, or sides of the heater
	• in high traffic areas

	CAUTION
	This heater creates warm air currents. These currents move heat
	to wall surfaces next to heater. Installing heater next to vinyl or
	cloth wall coverings or operating heater where impurities in the air
	(such as tobacco smoke) exist, may discolor walls.
	IMPORTANT: Vent-free heaters add moisture to the air. Although this is benefi-
	cial, installing heater in rooms without enough ventilation air may cause mildew
	to form from too much moisture. See Air for Combustion and Ventilation, pages 5
	through 8.
	CHECK GAS TYPE
	Use only natural gas. If your gas supply is not natural gas, do not install heater.
	Call dealer where you bought heater for proper type heater.
