CLEARANCES
As viewed from front of heater, the minimum
clearance from cabinet to combustible construction: Side
Wall – 1”; Floor – 2”; Ceiling – 11”.
In selecting a location for installation it is necessary
to provide adequate accessibility clearances for servicing
and proper operation. This appliance must not be connected
to a chimney flue that serves to vent a solid-fuel burning
(wood or coal) appliance, or a multi-vent system.
SAFETY RULES
A)
The wall furnace should be located near the center of
the house for best heat distribution.
B)
Due to high temperatures, the appliance should be
located out of traffic and away from furniture and
draperies.
C)
Children and adults should be alerted to the hazards
of high surface temperature and should stay away to
avoid burns or clothing ignition.
D)
Young children should be carefully supervised when
they are in the same room as the appliance.
E)
Do not place clothing or other flammable material on
or near the appliance. Precautions should be taken
so as not to place furniture, drapes, or other articles
directly in front of grille or lower access door that
would obstruct air openings as proper air flow is
critical to proper operation of unit.
F)
Any safety screen guard or casing front removed for
servicing an appliance must be replaced prior to
operating the appliance.
G)
Heater must be installed with legs resting on the 2x4
floor sill plate (recessed) or the factory FSK kit (flush
mount). The header plate shall then be installed at a
height 65-3/4 inches above top surface of the plate
that the heater legs rest on. This provides the listed
2 inch minimum floor clearance.
If the area where the heater is installed contains
carpeting, tile, etc., the listed 2 inch minimum floor
clearance must be maintained from the top surface of
these materials.
If the heater is installed DIRECTLY on carpeting, tile
or any combustible material other than wood flooring,
the heater shall be installed on a metal or wood panel
secured to the floor, extending the full width and depth
of the heater.
H)
Installation and repair must be done by a qualified
installer or service technician. The wall furnace must
be inspected before use and at least annually by a

CONTROLS
All controls are preassembled at the factory.
The normal manifold pressure should be 3.5”
w.c. on Natural Gas and 10” w.c. on L.P. Gas. The
maximum inlet pressure in the gas supply pipe should
never exceed 14” w.c. on L.P. Gas or 7.0” w.c. on
Natural Gas.
The appliance and its individual shutoff valve
must be disconnected from the gas supply piping system
during any pressure testing of that system at test
pressures in excess of ½ psig.
The appliance must be isolated from the gas
supply piping system by closing its individual manual
shutoff valve during any pressure testing of the gas supply
piping system at test pressures equal to or less than ½
psig.
The minimum inlet pressure in the gas supply
pipe should be 5.0” w.c. on Natural Gas or 11” w.c. on
L.P. Gas, “for purpose of input adjustment”.
The appliance is orificed at the factory for
elevations up to 2,000 feet. If installed above 2,000 feet,
the BTU input must be reduced 4% per 1,000 feet. See
the following orifice chart for the proper orifice for a
specific elevation. A blank orifice is shipped in the high
altitude kit with each heater. This orifice(s) will have to
be drilled to correct size by a qualified installer, service
technician or the gas supplier.
