WARNING
Failure to follow this warning could result in personal injury,
death, and/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.
FIRE, EXPLOSION, AND CARBON MONOXIDE
POISONING HAZARD
The furnace can be installed horizontally in an attic or crawl space
on bottom or 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 Fig. 9 and 10.)
Secure 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 3/4-in. screws in
the bottom of the furnace casing for each strap. (See Fig. 9 and 10.)
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 and 11.) For furnaces with 1-in.
clearance requirement on side, set furnace on noncombustible
blocks, bricks or angle iron. For crawl space 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.
Roll-Out Protection
Provide a piece of sheet 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 12in. (305 mm) and
larger may be used for flame roll-out protection when bottom of
furnace is used for return air connection. See Fig. 11 for proper
orientation of roll-out shield.
