User’s Information
UPFLOW/HORIZONTAL WITH FILTER KIT
The filter rails are spring loaded for automatic adjustment to
allow standard size, locally obtainable replacement filters.
The filter rack itself slides to adjust to the required width
needed for bottom or side return. Always insert the chamfer
(angle edged sides) end first.
The furnace filter may be secured with filter retaining
brackets for right side return on smaller furnaces. To replace
filters on these furnaces, remove the blower access door, push
back to flex the filter and clear the filter retaining bracket at
the front of the unit. Gently pull the filter out.
After cleaning, replace the filter in the same manner making
sure that filter is secured in place in both front and back filter
retaining brackets of the unit. Replace blower access door.
Air filters may also be located outside of the furnace using a
SIDE FILTER FRAME.
Upflow / Horizontal Furnace Filters
The Upflow/Horizontal furnace, when installed horizontally,
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 cabinets.
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.
