Clearances
1. In selecting a location for installation, it is necessary to provide
adequate accessibility clearances for servicing and proper installation.
2. The FAW-40 can be attached to the wall or recessed into the wall up
to 9 1/2 inches (24.1cm) in depth. Note:
Do not place combustible
header or material on top of unit when installed in wall.
Maintain 3/4" minimum spacing above heater.
3. The wall in which the furnace is recessed has (0) zero (0mm)
clearance to the furnace sides.
4. When using side discharge registers, SOR-1 or SOK-1, the furnace
cannot be recessed into the wall.
5. Clearance to sidewall or combustible material is 4 inches (10.2cm).
6. Ceiling clearance is 4 inches (10.2cm).
7. Floor and rear wall clearance is (0) zero inches (0mm).
8. Clearance of 18 inches (46cm) is required to adjacent wall or

Before Installing Consider The Following Venting
1. A chimney for residential-type or low-heat gas utilization equipment
shall extend at least 3 feet (914mm) above the highest point where
it passes through a roof of a building and at least 2 feet (610mm)
higher than any portion of building within a horizontal distance of 10
feet (3m).
2. This furnace must not be connected to a chimney flue serving a
separate solid-fuel burning appliance.
3. Uninsulated Single-Wall Metal Pipe shall not be used outdoors
in cold climates for venting gas utilization equipment.
4. Attention! This Fan Type Vented Wall Furnace is equipped with a
vent safety switch. In the event of spillage of flue products due to
improper venting the vent safety switch will open, which results in
the main burners to "shut off".
Model No. FAW-40 may be vented as shown in Figure 4. The vent
cap termination must be at least 12 feet (3.7m) above the floor and
