Two high velocity type air filters are required for each down-
flow furnace. Downflow furnace filters must be located
outside the furnace cabinet. Typical installations are shown
in Figures 23 and 24. Tables 7 and 8 (page 13) provide
information for installation of the filter retaining brackets
shipped with downflow furnaces.

Optional horizontal filter conversion kits are BAYFLTR203
for 17 1/2" width cabinets, BAYFLTR204 for 21" width
cabinets, and BAYFLTR205 for 24" width cabinets. These

RETURN AIR FILTERS FOR UPFLOW FURNACE
IN HORIZONTAL CONFIGURATION
When the Upflow Furnace is installed in a horizontal configu-
ration, the filter must never be installed inside or outside the
cabinet directly above the blower assembly. See Figure 11
(page 9). Remote filter grilles may be used for homeowner
convenience or the filters may be installed in the duct work
upstream of the furnace. See Figures 11 (page 9) and 21 (page
11).

1. Determine the location to be used. The furnace cabinet
has dimples for location of the alternate furnace clips
(Side return only). Pre-drill clearance holes with a
3/16" drill. Bottom return holes are pre-drilled.
2. Install the clips in front and rear of the desired location
using the screws provided. The filter clip with the leaf
spring mounts in the rear of the cabinet. See Figure 22.

A score line and the words “CUT HERE” are located on the
