Instructions to Assemble the Perfect Platform™
For Model FB2843-M8
Refer to diagram on other side
Door
Place the handle on the door using the two #6 x ½” screws provided. Note: Only one of the doors has holes to
attach the handle. This door is to be located on the side which the homeowner has access for replacing the
filter.
Filter Rail Adaptors and Spacer
The filter spacer (4) is placed to the back of the filter track, closest to the door which is not accessible. The open
side of the spacer will be against the door.
The filter rail adaptors (5) are not provided or used on the
FB2843-M8
model. The only filter which fits this unit
properly is the
M8-1056
filter.
Adjustable Center Crossbar
The center crossbar (1) is secured to the platform with the formed flanges down. Place the crossbar in place but
do not secure it to the platform until the intake duct adjuster (2) is in place.
On the
FB2843-M8
platform this crossbar can be adjusted to close the gap for a narrow air handler or furnace.
Duct Flanges
The flat duct flanges (6) need to be bent up 90° and are used to secure the intake duct to the platform.
On the
FB2843-M8
the intake duct adjuster (2) can be placed allowing for either 10” or 12” duct. The formed
flange should be facing up and is used to secure the intake duct to the platform. Once the adjuster is positioned
correctly four #8 x
3
/
8
” screws are used to secure both the adjuster and crossbar to the platform. One screw is
used to secure the adjuster to the crossbar.
Optional Blocking Plate
This plate (3) is used for Heat Wave 80 Series furnaces to close off the open area at the front of the furnace. This
plate has holes for mounting but you will need to drill holes in the platform.
Once the air handler or furnace and the duct are in place and secured the joints must be properly sealed to prevent air
leakage.
