on wall surface above furnace.
On Solid Wall
3a. After locating mounting holes, attach two #10 x 1 1/2-inch screws
provided in blower kit into wall. Do not completely tighten screwheads
to wall, leave a 7/16-inch gap between screwheads and wall.
On Sheet Rock Wall
3b. After locating mounting holes, drill two 5/16-inch diameter holes
into wall. Insert the two plastic expansion anchors into holes. Insert
two #10 x 1 1/2-inch screws provided in blower kit into two plastic
expansion anchors. Do not completely tighten screwhead to plastic
expansion anchors, leave a 7/16-inch gap between screwheads
and plastic expansion anchors. Refer to Figure 12.
4. At the top of outer casing remove one screw from center clearance
hole that attaches outer casing to header assembly. Also, remove
two screws that attach bottom of outer casing to inner casing.
5. Pull the outer casing forward approximately 1 inch away from
wall surface.
6. Remove four 8 x 3/8-inch screws that attach blower front to blower
housing. Separate blower front from blower housing. Remove
blower housing by disconnecting fan switch wire assembly from
power cord and motor wire.
Caution: When removing blower front be careful not to damage
motor coil wires. Damaged coil wires will disable blower function.
7. Position blower housing on top of header assembly and route three-
prong cord set between left side of outer casing and inner casing.
Caution: Blower cord set routing is important. Cord set should
be in proper location to avoid being overheated. Incorrect routing
of cord set may result in damage to cord set.
8. Replace the outer casing to the wall surface.
9. Attach outer casing to header assembly. Attention: The center
clearance hole will not be used. The two outside clearance holes
will be used to attach outer casing to header assembly, one screw
from Step 4 and one screw supplied in hardware package. Refer
to Figure 11.
10. Attach outer casing to inner casing with two screws from Step 4.
11. Align key hole slots on back of blower housing with the two screws
attached to wall. Position blower housing flush with wall surface
