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
