If a factory-supplied external Filter/Media cabinet is provided,
instructions for its application, assembly, and installation are
packaged with the cabinet. The Filter/Media cabinet can be used
with the factory-supplied washable filter or a factory-specified
high-efficiency disposable filter (see cabinet instructions).
→
If installing the filter in the furnace blower compartment, deter-
mine location for filter and relocate filter retaining wire if
necessary. See Table 2 to determine correct filter size for desired
filter location. Table 2 indicates filter size, location, and quantity
shipped with this furnace. See Fig. 2 for location and size of
bottom and side return-air openings.

1. A 1 In. clearance minimum between top of
furnace and combustible material.
2. The entire length of furnace must be
supported when furnace is used in horizontal
position to ensure proper drainage.
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 cloth-
ing. Failure to follow this caution could result in personal
injury.
CAUTION: For airflow requirements above 1800 CFM,
see Air Delivery table in Product Data literature for
specific use of single side inlets. The use of both side
inlets, a combination of 1 side and the bottom, or the
bottom only will ensure adequate return air openings for
airflow requirements above 1800 CFM.
NOTE: Side return-air openings can ONLY be used in UPFLOW
configurations. Install filter(s) as shown in Fig. 18. Bottom
return-air opening may be used with all 4 orientations. Filter may
need to be cut to fit some furnace widths. Install filter as shown in
Fig. 19.
NOTE: Remove and discard bottom closure panel when bottom
inlet is used.
