NOTE: Requirements for sealing ductwork vary

from region to region. Consult with local codes for requirements speciﬁ c to your area.

Round Duct Connector Installation

The 14” round duct connector is designed to connect directly to a 14” ﬂ exible 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 ﬂ oor 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 ﬂ oor with appropriate size screws.

5. Connect the round supply duct to the underside of the duct connector and secure them with ﬁ eld supplied sheet metal screws.

6. Seal all connections with industrial grade sealing tape or liquid sealant.

Alcove Installation

1. Cut alcove rough openings to minimum dimensions shown in Figure 13 (page 12).

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 ﬂ ange 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

minimum. For special clearances between 1” - 5”, requirements are a louvered door with a minimum of 250 in2 (1613 cm2) 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 for return air opening requirements.

2. Insert four fasteners, securing grille to door or wall.

Downﬂ ow Furnaces

For typical unducted return air downﬂ ow 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-ﬂ oor supply duct system with a ducted or unducted return air system. Duct connectors are recommended for this application. See Table 2 (page 10).

NOTE: Requirements for sealing ductwork vary

from region to region. Consult with local codes for requirements speciﬁ c to your area.
