Figure 20
. Drill through the top casing flange and fasten
each side with a sheet metal screw. This plate covers the
space between the top of the furnace and wall opening
after electrical connections are made.
MOUNT FURNACE THROUGH WALL
Mount the furnace through the wall using surface or
recessed mounting instructions.
See Pages 11 - 15
.
Refer to
Figure 19
for the following steps.
1. Check to see that the air tube protrudes through wall
7/8-inch min. to 1-inch max. for proper seal in vent cap.
2. Check to see that the vent tube protrudes past the air
tube 1/8 inch min. to ¼- inch max. for proper seal in
vent cap.
3. Apply a single strip of mastic (“E” provided in the vent
cap carton) continuously around the outer edge of the
vent cap mounting plate.
4. Holding the vent cap in an upright position (embossed
“top” on the mounting plate towards the top of the
furnace), push it into place until the stops
are contacted. If the stops prevent the mounting plate
from reaching the wall, refer back to “DETERMINE
PROPER LENGTHS”
Page 13
.
NOTE:
The smaller tube in the vent cap must slide over
the vent “B”.
5. Fasten the vent cap mounting plate to the wall with
(4) 1½-inch wood screws “D’’ provided.
6. On masonry construction, drill into the wall and use
plugs or anchors. Additional sealant (silicone) may be
required if the mounting surface is uneven.
