NOTE - Heavy-gauge perforated sheet metal straps
(plumbers' straps) may be used to suspend the unit from
roof rafters or ceiling joists. When straps are used to sus-
pend the unit in this way, support must be providedfor both
the ends and the middle of the furnace to prevent sagging.
The straps must not interfere with the plenum or exhaust
piping installation. Securing screws should be 1/2 inch
from the top edge and 1-1/2 inch from the side edge in all
cases. Cooling coils and supply and return air plenums
must be supported separately.
NOTE - When the furnace is installed on a platform in a
crawlspace, it must be elevated enough to avoid water
damage and to allow the evaporator coil to drain.
Return Air -- Horizontal Applications
Return air can be brought in through the end of a furnace
installed in a horizontal application. The furnace is
equipped with a removable bottom panel to facilitate
installation. See figure 9.
