INSTALLATION – Setting Equipment
Shipping Bolt Removal
NOTE: Unit is equipped with a 1/2 hp blower motor which
has three flexible legs and one rigid leg. The rigid leg is
equipped with a shipping bolt and a flat white plastic washer
(rather than the rubber mounting grommet used with a flexible
mounting leg). See Figure 8. The bolt and washer must
be removed before the furnace is placed into operation.
After the bolt and washer have been removed, the rigid leg
will not touch the blower housing.
WARNING
Blower access panel must be securely in place when
blower and burners are operating. Gas fumes, which
could contain carbon monoxide, can be drawn into living
space resulting in personal injury or death.

WARNING
Do not install the furnace on its front, back or in the
horizontal position. See Figure 10. Do no connect the
return air ducts to the back of the furnace. Doing so will
adversely affect the operation of the safety control
devices, which could result in personal injury or death.
Select a location that allows for the required clearances that
are listed on the unit nameplate. Also consider gas supply
connections, electrical supply, vent connection, condensate
trap and drain connections, and installation and service
clearances [24 inches (610 mm) at unit front]. The unit must
be level from side to side. Tilt the unit slightly (maximum 1/
2 in. from level) from back to front to aid in the draining of
the heat exchanger. See Figure 9.
NOTE: These units may be equipped with a shipping pad
under the blower housing. Remove the shipping pad prior
to operation.
Allow for clearances to combustible materials as indicated
on the unit nameplate. Minimum clearances for closet or
alcove installations are shown in Figure 11.
