Installation - Setting Equipment

Do not install the furnace on its front, back or in the
horizontal position. 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. Unit may be posi-
tioned from level to 1/2" toward the front to aid in draining.
