INSTALLATION IN HORIZONTAL APPLICATIONS

These furnaces can be installed horizontally in either horizontal
left or right discharge position. In a crawlspace, furnace can either
be hung from floor joist or installed on suitable blocks or pad.
Furnace can be suspended from each corner by hanger bolts and
angle iron supports. (See Fig. 17.) Cut hanger bolts (4 each 3/8-in.
all-thread rod) to desired length. Use 1 X 3/8-in. flat washers,
3/8-in. lockwashers, and 3/8-in. nuts on hanger rods as shown in
Fig. 17. Dimples are provided for hole locations. (See Fig. 2.)

CAUTION:

The entire length of furnace MUST be

supported when furnace is used in a horizontal position to
ensure proper draining. When suspended, bottom brace
supports sides and center blower shelf. When unit is
supported from the ground, blocks or pad should support
sides and center blower shelf area.
