bottom return application. See Table 3 to determine correct filter
size for desired filter location. Table 3 indicates filter size,
location, and quantity shipped with the furnace.
For bottom air-return applications, filter may need to be cut to fit
some furnace casing widths. A bottom closure panel is factory
installed in the bottom of the furnace. When bottom return inlet is
desired, remove and discard the bottom closure panel. Two sets of
hardware are needed for furnaces in 24-1/2-in. wide casings using
2 filters for bottom return. All hardware is provided for filter
installation.
CAUTION:
Use care, when cutting support rods in
filters, to protect against flying pieces and sharp rod ends.
Wear safety glasses, gloves, and appropriate protective
clothing. Failure to follow this caution could result in
personal injury.
NOTE:
Furnaces with a 17-1/2-in. wide casing require an addi-
tional procedure when locating the filter for bottom return-air
application. Field fabricate a sheet metal filler strip 1 X 3 X 24-1/2
in. and install it along side of the filter as shown in Fig. 6. Drive
2 screws through the casing side and into the filler strip to secure
it in place. Filter should rest on the top of the filler strip when
installed.
III.
LEVELING LEGS (IF REQUIRED)
When furnace is used with side inlet(s) and leveling legs are
required, refer to Fig. 7 and install field-supplied, corrosion-
resistant 5/16-in. machine bolts and nuts.
NOTE:
The maximum length of the bolt should not exceed 1-1/2
in.
1. Lay furnace on its back. Locate and drill a 5/16-in. diameter
hole in each bottom corner of furnace as shown in Fig. 7.
