WARNING
!
FIRE, EXPLOSION, AND CARBON MONOXIDE
POISONING HAZARD
Failure to follow this warning could result in personal injury, death, or
property damage.
Do not install the furnace on its back or hang furnace with control
compartment facing downward. Safety control operation will be
adversely affected. Never connect return-air ducts to the back of the
furnace.
Horizontal Installation
The furnace can be installed horizontally in an attic or crawlspace on
either the left-hand (LH) or right-hand (RH) side. The furnace can be
hung from floor joists, rafters or trusses or installed on a
non-combustible platform, blocks, bricks or pad.
Suspended Furnace Support
The furnace may be supported under each end with threaded rod, angle
iron or metal plumber's strap as shown. (See
angle iron to bottom of furnace as shown. Heavy-gauge sheet metal
straps (plumber's straps) may be used to suspend the furnace from each
bottom corner. To prevent screws from pulling out, use 2 #8 x 3/4 in.
screws into the side and 2 #8 x in. screws in the bottom of the furnace
casing for each strap. (See
Fig. 15
If the screws are attached to ONLY the furnace sides and not the bottom,
the straps must be vertical against the furnace sides and not pull away
from the furnace sides, so that the strap attachment screws are not in
tension (are loaded in shear) for reliable support.
Platform Furnace Support
Construct working platform at location where all required furnace
clearances are met. (See
Fig. 2
mm) clearance requirement on side, set furnace on non-combustible
blocks, bricks or angle iron. For crawlspace installations, if the furnace
is not suspended from the floor joists, the ground underneath furnace
must be level and the furnace set on blocks or bricks.

metal for flame roll-out protection in front of burner area for furnaces
closer than 12-in. (305 mm) above the combustible deck or suspended
furnaces closer than 12-in. (305 mm) to joists. The sheet metal MUST
extend underneath the furnace casing by 1-in. (25 mm) with the door
removed.
The bottom closure panel on furnaces of widths 17-1/2-in. (445 mm) and
larger may be used for flame roll-out protection when bottom of furnace
