In addition to the requirements outlined previously, the
following general recommendations should be considered
when installing one of these furnaces:
•
Place the furnace as close to the center of the air
distribution system as possible. The furnace should also
be located close to the chimney or vent termination point.
•
When the furnace is installed in an attic or other insulated
space, keep insulation away from the furnace.
•
When the furnace is installed in an unconditioned space,
consider provisions required to prevent freezing of
condensate drain system.
Installation – Setting Equipment
Do not install the furnace on its front or its back. See
Figure 5. 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.
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 4.
