Preparing Floor Opening(s)

1.Mark fl oor opening(s) as shown in Figure 6. Provide minimum clearances at rear and right side walls of closet or alcove for installation of furnace and wiring.

2.Cut floor opening on outside edge of marked line so that opening is slightly larger than area marked.

3.Additional provisions may be necessary for optional air conditioning or heat pump if refrigerant lines are installed elsewhere than at the front of the furnace.

4.The refrigerant and entrance supply opening dimensions may be adjusted ± 1/2”.

Installing Duct Connector

NOTE: The duct connector is designed for use on ducts down to 12” wide. On typical ducts, the fi nger tab duct connector may be installed using Method B. On narrow ducts, there may be insuffi cient clearance to bend the tabs on two sides of the fi nger tab duct connector. In such
