INSTALLATION – Setting Equipment
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 11.
Shipping Bolt Removal
NOTE: Units with a 1/2 hp & 3/4 hp blower motors are
equipped with 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 10. 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.
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 13.
