Upflow / Horizontal Furnace Filters

The Upflow/Horizontal furnace, when installed horizon- tally, requires a horizontal filter kit. The filters may be located remote to the furnace or in the return air duct near the furnace. Check with your dealer for the location of your filters.

An upflow/horizontal furnace in horizontal return air filter application, as shown, features two 14" x 20" x 1" filters in the 14-1/2" wide furnace cabinets; or two 16" x 20" x 1" filters in the 17-1/2", 21", and 24-1/2" wide furnace cabi- nets.

UPFLOW/HORIZONTAL WITH FILTER KIT

To replace filters, remove the filter access door, lift the filter from the lower bracket and shift the filter to the side to free the top filter from the bracket and slide the filters out through the filter access door. After cleaning, replace the filters in the same manner making sure that the filters are secured in place in both top and bottom filter brackets. Replace filter access door.

Air filters may also be located outside of the furnace using a remote filter grille. The filter grille could be in a hallway, wall, or in the ceiling. Check with your dealer for the exact location of your filter and the method of changing the filters.
