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 instaflation. Securing screws should be 1/2 inch from the top edge and 1-1/2 inch from the side edge in aft 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.
