2. Remove refrigerant line knockouts in fur-
nace only when installing indoor coil of an
air conditioner or heat pump system, or for
hook-up of a VentilAire accessory when
the furnace is used in the upfl ow position.
Refer to instructions supplied with accessory
equipment.
3. Remove unit front door and slide back until
bottom slots in rear of unit engage with both
tabs of optional rear mounting plate, OR...
If mounting plate is not used, an equivalent
method of securing the rear of the unit may
be used as long as it prevents displacement
during transport if used in a manufactured
home.
NOTE: The furnace does not need to be hard
up against the rear mounting plate. The tabs will
engage into the slots and allow approximately
1/2” of furnace adjustment front to back and
right to left.
4. Secure front of unit with one or more fas-
teners at mounting hole(s) provided or at
tie-down tab (see Figure 16).
