Installation (cont.)
INSTALL VENT CAP
Outside, place a single strip of mastic (provided) around
the back flange of the vent cap ("G" Fig. 5, page 8). In-
stall the vent cap by inserting it into the air inlet tube and
over the vent tube.
IMPORTANT
The top of the vent cap is embossed "TOP". Install it in
the correct position to prevent water from entering the wall.
Level the vent cap and attach it to the outside wall with
four (4) #8 roundhead (long) screws (Fig. 6).
If the wall surface is not flat (shiplapped siding, etc.) or
less than 5 inches thickness use Thin Wall Collar Kit (9307)
or, build up a flat surface with wood strips. Do not tilt or
bend cap to fit uneven surfaces. The vent cap flange must
be tight against the wall to prevent rain or wind penetra-
tion. Use standard caulking compound if required (not
provided).
\
For brick, masonry or plaster walls, it may be necessary \
to use lag screws or expanding anchor bolts which are
k
not furnished with the furnace.
