UPFLOW INSTALLATION:
Vent positioning, pressure switch location and drain locations shall be performed in
accordance with instructions in the appropriate sections of this manual.
IMPORTANT
:
• THE FURNACE MUST BE INSTALLED ON A LEVEL SURFACE. IT IS RECOMMENDED
THAT THE REAR OF THE FURNACE BE ELEVATED 1/4” (6mm) HIGHER THAN THE
FRONT TO FACILITATE PROPER CONDENSATE DRAINAGE.
• IF THE FURNACE AND AIR CONDITIONER IS LOCATED ABOVE A FINISHED SPACE,
INSTALL A DRAIN PAN UNDERNEATH THE UNIT.
NOTE
This furnace is approved for installation in attics, alcoves, utility rooms, closets and crawl spaces. If this
furnace is to be installed in a utility room, be sure that it is located in such a way as to allow access for
servicing or the removal of other appliances installed in the room (hot water heater, for example). It is not
permissible to use a rear return on this appliance. Use only side and bottom returns.
H8.4.3
This furnace may be used as part of an air conditioning system. The furnace wiring and control system is “air
conditioning ready.” There are the following factors to consider:
The air conditioning evaporator coil must be downstream of the
heat exchanger. The cooled air passing over the warmer heat
exchanger tubes can cause condensation inside the tubes,
resulting in corrosion and premature failure.
A parallel duct system can be installed to direct the air from the
furnace through the evaporator coil only. Use dampers or other
means to bypass the heat exchanger. If (summer/winter) dampers
are used, they should be interlocked to prevent system operation
unless the dampers are in the full open or full closed position.
NOTE
If installing a two stage air
conditioning system, clip the JW38
jumper wire between Y (low cool)
and Y2 (high cool) on the furnace
control board.
Control defaults to Y2 (high cool) if
JW38 jumper wire is NOT cut.
