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
2 screws 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.
NOTE:
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.
