Installation – Setting Equipment
Upflow Applications
This gas furnace can be installed as shipped in the upflow
position. Refer to Figure 10 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, for proper operation.
It is
recommended to tilt the unit slightly toward the drain to insure
proper drainage. See Figure 5.
Figure 4
Do not install the furnace on its front or its back. See
Figure 4.
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.
