Side Mounted Filter Rack

Figure 43
Filter Installation using Optional Filter Rack
When installing or removing a bottom mounted filter, slide the two
side filter clips to the back of the furnace BEFORE installing or
removing. This will allow the filter to clear the front raised edge of
the furnace. Insert filter into side clips first and push filter back until
it is fully engaged into back clip. When filter is in place, slide clips
back into place midway on filter as shown in Figure 44 and
Figure 45.

Refer to Figure 46 and for guidelines to install filters. Furnaces
which require larger filter media and have limited clearances on
one side of furnace, require a standoff filter rack, see Figure 46,
available from your distributor.

CAUTION
!
REDUCED FURNACE LIFE HAZARD.
Failure to follow this caution may result in reduced
furnace life.
If filters are only suitable for heating application,
advise homeowner that filter size may need to be
increased if air conditioning is added.
Addition Of Air Conditioning
When a refrigeration coil is used in conjunction with this unit, it
must be installed parallel with or on the discharge side of the unit to
avoid condensation on the heat exchanger. All furnaces are
designed with a break--away duct flange on the supply air side of
the furnace. This allows for installation in the horizontal right or
downflow applications. The coil installation instructions must be
consulted for proper coil location and installation procedures. With
a parallel flow arrangement, dampers must be installed to prevent
chilled air from entering the furnace. If manually operated dampers
are used, they must be equipped with a means to prevent
operation of either unit unless the damper is in full heat or full cool
position.
A 3" clearance is required on the right side of the furnace in order to
run the copper or plastic condensate drain line.
Downflow Furnace Installation
Non- Combustible Floor Installation
Fabricate a plenum to the dimensions given in Table 13, for the
furnace outlet. Plenum should be flanged, approximately
support.
Note: The three(3) screws in the top panel of the furnace next to
the duct flange MUST be removed to provide serviceability of the
primary heat exchangers in the downflow installation
1. Position plenum through the floor and set the furnace over
the opening in the floor. If necessary, grout around the base
to seal air leaks between the base and the floor.
Combustible Floor Installation
WARNING
!
FIRE HAZARD.
Failure to follow this warning could result in
personal injury, death and/or property damage.
Place furnace on noncombustible subbase on
downflow applications, unless installing on non- -
combustible flooring.
