The gas furnace can be installed as shipped in either the
upflow position or the horizontal position.
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, and
installation and service clearances [24 inches (610 mm) at
unit front]. The unit must be level.
NOTE: Units with 1/2 hp blower motors are equipped with
three flexible legs and one rigid leg. See Figure 7. 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). 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.
Setting Equipment
WARNING
Do not install the furnace on its front or its back. 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.
Upflow Applications
Allow for clearances to combustible materials as indicated
on the unit nameplate. Minimum clearances for closet or
alcove installations are shown in Figure 8.
