RETURN AIR FILTERS FOR UPFLOW FURNACE IN
HORIZONTAL CONFIGURATION
When the Upflow Furnace is installed in the horizontal
configuration, the return air filters must be installed
exterior to the furnace cabinet. Remote filter grilles
may be used for homeowner convenience or the filters
may be installed in the duct work upstream of the fur-
nace. See Figure 17.

cabinet has dimples for location of the alternate fur-
nace clips (Side return only). Pre-drill clearance
holes with a 3/16" drill. Bottom return holes are
pre-drilled. See Figure 21.
2.Install the clips in front and rear of the desired loca-
tion using the screws provided. The filter clip with
the leaf spring mounts in the rear of the cabinet.
