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).

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 include filters and brackets necessary for horizontal filters. In addition, optional door kit BAYFLTR206 is also available. See Figures 21 and 24.

INSTALLING THE OPTIONAL FILTER

The filter may need to be cut to fit the unit depending on the location of the return air filter.

A score line and the words “CUT HERE” are located on the end of the filter. If your application requires cutting the filter, do so as indicted by the score mark.
