b. Cut ceiling and roof holes as follows: Ceiling Hole = 8-3/4" (222 mm) diameter Roof Hole = 9-3/8" (238 mm) diameter

c. DO NOT ALLOW DEBRIS TO FALL INTO THE FURNACE. THIS COULD CAUSE UNSAFE OPERATION AND VOIDS THE FURNACE WARRANTY. Use the top cap that comes with the furnace packaging (or alternate protector) to prevent debris from falling into the furnace before the final roof jack connection is made.

CUT DUCT OPENING (FINGER TABBED ONLY)

a.Place duct connector through the floor open- ing with bottom tabs resting on top of the supply air duct.

b.Center duct connector and push back against rear edge of floor opening.

c.Mark cut-out location (tab area) and remove duct connector.

d.Cut out duct opening 1/4" larger than area marked.

INSTALL FURNACE MOUNTING PLATE

a. Place mounting plate (supplied within duct connector) at rear of the floor opening (See Figure 15).

INSTALLING PLATINUM SERIES 14” ROUND DUCT CONNECTOR

a.Place duct connector through the floor open- ing. (See Figure 15).

b.Secure duct connector to floor.

INSTALLING SCREW DOWN DUCT CON- NECTOR

a. Apply a bead of caulking, mastic, or other approved sealant around bottom side of 1/2” flange and restrictor plate, when applicable. b. Locate the duct connector over duct and carefully lower screw down duct connector

into place.

c. Once duct connector is located on duct, temporarily hold in place while fastening duct connector to the floor using flat head screws or nails. Be sure flanges of duct connector stay in contact with the duct.

d. Screw plenum to duct making sure a seal is made between the duct and the duct connec- tor. Additional screws may be added if re- quired.

e. Cut away duct along edge of flange allowing the center to drop into the duct. Remove section of duct with caution, as edges will be sharp.

INSTALLING FINGER TABBED DUCT CON- NECTORS

a.Place duct connector through the floor open- ing with bottom tabs extending through the duct opening. (See Figure 15)

b.Secure duct connector to floor.

c.Bend bottom tabs under and up tightly against the supply air duct (See Figure 16).

NOTE: The duct connector is designed for use on ducts 12" in width. When using the connector on 12" wide ducts, there may be insufficient clearance to bend the tabs on two sides of the duct connector. In such cases the tabs may be attached to the sides of the duct by using sheet metal screws or other suitable fasteners. (See Figure 17).

If sealant, mastic, or tape is used to provide a better seal, it should be approved by applicable national or local codes.

ALTERNATE ATTACHMENT METHODS

This procedure may also be used to install a furnace duct connector to narrow metal ductwork where insufficient clearance prevents
