Should acidic compounds form in the furnace they may significantly reduce the useful life of
the furnace.
a. The Combustion Air Intake piping may enter the furnace thru either the top, left or right side
as depicted in Figure 7A-D. Upon selection of the location to exit the furnace, cut out the
appropriate knock-out and install the Intake Air Flange provided using 4 self-tapping screws.
b. A section of 2-inch PVC pipe should then be inserted into the Intake Air Flange, using silicone
caulk to seal the pipe to the flange. The pipe may protrude into the furnace up to 1 inch past
the flange. For increased rigidity, a self-tapping screw may be installed thru the flange into the
PVC pipe.
