Included in the accessory carton is a white sheet metal bracket that is 8-1/4 inches high and 3-1/4 inches wide. It has a 7/8” hole in it 6 inches from the bottom. Right below the 7/8” hole are 2 screw holes. This bracket also has 2 screw mounting holes on the bottom 1-1/4 inch flange. (Shown in Fig. 15)

1.Place the sheet metal plenum on top of the 24” X 24” warm air duct opening.

2.Attach the fan/limit control mounting bracket to the top of the furnace using sheet metal screws to attach the bracket into the screw holes (pre drilled) that are on the furnace.

3.With the fan/limit control bracket up against the sheet metal plenum, either drill a 7/8” hole and two 1/8” holes through the holes into the sheet metal plenum or use the bracket as a template.

4.Screw the mounting bracket onto the bracket with the

2screws that are furnished.

5.Install the fan/limit control through the mounting bracket and into the plenum.

6.Tighten the mounting bracket set screw into the fan/limit control.

If you intend to install air conditioning, the air conditioning coil should be mounted above fan limit control. Use metal water drain pan only.

Do not use a plastic pan as high temperatures resulting from electric power failure or furnace fan failure could result in fire.
