3. Assemble the following parts using 6 #8 sheet metal screws. Both “B” and “C” panels should t inside the bottom “A” panel anges.

Attach “B” and “C” (side panels) to “A” (bottom panel). After the bottom and sides are assembled, attach “A” (top panel) using 6 #8

sheet metal screws provided.

4. Position the assembled lter box on rear of furnace, supporting it rmly up to electrical enclosure, covering the rear distribution blower.

Make sure the lter box is tightly pressed to the back of the furnace. Use 4 1/4” bolts (included) to rmly attach the lter box to sides of

furnace.

The lter box requires one 20” x 20” x 1” lter (not included, but

available at most hardware and home centers).

For maximum furnace efciency, inspect your lter regularly

and replace the lter when airow is restricted and the lter

appears dirty. Some environments may require more frequent

changing of the lter. Failure to replace the lter will result

in excessive temperatures causing poor performance and

damage to the furnace. It is strongly recommended to use less

restrictive, low cost lters.
