	(i.e. gas valve, etc.) that make the heater work. There are no owner serviceable items contained in this box.
Front Fixed Hanger	Provides rigid support and mounting surface for the reflector. Holes are provided in the upper corners of the
	bulkhead to accommodate suspension hardware required for installation of the heater.
Reflector	The reflector is made from formed aluminum and reflects the radiant energy downward to the space to be
heated.
Heat Exchanger	A U-shaped tube through which the heated products of combustion pass.
Rear Movable Hanger	Provides support for the heat exchanger and reflector at the end that is furthest from the burner box. The
	support may be moved (within limits) to accommodate hanging of the unit.
Service Door	To be removed only by a licensed contractor. Removal of this service door provides access to the electrical and
	gas distribution components.
Intake Vent	Accomondates a 3" diameter combustion air inlet duct that delivers fresh air to the burner.
Exhaust Vent	Accomondates the air-venting duct that carries the products of combustion to be vented outdoors.
