Shipping Bolt Removal
Units with 1/2 hp & 3/4 hp blower motor are equipped with
three exible legs and one rigid leg. The rigid leg is equipped
with a shipping bolt and a at white plastic washer (rather
than the rubber mounting grommet used with a exible
mounting leg). See Figure 11. 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.

Upow Applications
The gas furnaces can be installed as shipped in the upow
position. Refer to Figure 13 for clearances. 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 12.
Allow for clearances to combustible materials as indicated
on the unit nameplate.

WARNING
Do not 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.
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.
