Round Duct Connector Installation
The 14” round duct connector is designed to connect
directly to a 14” flexible duct.
NOTE: Flexible ducts must
have a minimum temperature rating of 200° F and meet
all applicable codes and standards.
1. Apply a bead of caulking, mastic, or other approved
sealant around bottom side of connector.
2. Install and center the duct connector in the floor opening.
3. Install the mounting plate under the back side of the
duct connector. See Figure 12 . NOTE: Align the screw
holes in both components.
4. Secure the duct connector and the mounting plate to
the wood floor with appropriate size screws.
5. Connect the round supply duct to the underside of the
duct connector and secure them with field supplied
sheet metal screws.
6. Seal all connections with industrial grade sealing tape
or liquid sealant.
NOTE: Requirements for sealing ductwork vary
from region to region. Consult with local codes for
requirements specific to your area.
Alcove Installation
1. Cut alcove rough openings to minimum dimensions
shown in Figure 13 .
2. Attach frame assembly with four fasteners (provided or
equivalent) into pre-punched holes on top of furnace.
See
Figure 2 (page 7) . NOTE: If additional securing
is required, attach each side of frame assembly to alcove
opening using holes provided.
3. Attach return air grille to frame assembly by hooking
grille over flange on top of frame and into channel on
bottom.
Closet Installation
For proper air circulation, closet installations require a
return air grill installed in the door or a partially louvered
door across the opening. For clearances 6” or greater, the
closet must have an open free area of 235 in
2
minimum.
For special clearances between 1” - 5”, requirements are
a louvered door with a minimum of 250 in
2
(1613 cm
2
) free
area. A fully louvered closet door is strongly recommended
for both installation types. For closet installations, the return
air grille mounting frame is not used since the furnace is
located inside the closet. For examples of both types of
installations, see
Figure 14 (page 12) .
1. Cut return air opening in desired position in door or
wall, preferably above top of furnace. Refer to Table 1
(page 5) for return air opening requirements.
2. Insert four fasteners, securing grille to door or wall.
Downflow Furnaces
For typical unducted return air downflow applications,
an air-conditioner or heat-pump coil can be installed by
mounting the coil directly on top of the furnace without
adding sheet metal cavities or cutting and trimming wood
panels. Unducted return air systems may be used for
closet or alcove installations.
The steps below describe installation procedures for
an under-the-floor supply duct system with a ducted
or unducted return air system. Duct connectors are
recommended for this application. See
Table 2 (page
10) .
1. Route 240V supply circuit(s) and 24V wiring to closet
or alcove. See Figure 20 (page 17) for locations.
2. Remove refrigerant line knockouts in furnace 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 upflow 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. If mounting plate is not used, an
