Horizontal applications, in particular, may dictate many of
the installation’s specics such as airow direction, ductwork
connections, ue and/or combustion air pipe connections, etc.
The basic application of this furnace as a horizontal furnace
di󰀨ers only slightly from an upright installation. When installing
a furnace horizontally, additional consideration must be given
to the following:

In horizontal applications the condensate drain trap is secured
to the furnace side panel, suspending it below the furnace.
A minimum clearance of 5.5” below the furnace must be
provided for the drain trap. Additionally, the appropriate
downward piping slope must be maintained from the drain
trap to the drain location. Refer to Condensate Drain Trap and
Lines section in this manual or the installation instructions for
further details. If the drain trap and drain line will be exposed
to temperatures near or below freezing, adequate measures
must be taken to prevent condensate from freezing. 
The use of insulation and/or heat tape is recommended.
Failure to provide proper condensate drainage can result in
property damage.

Leveling ensures proper condensate drainage from the heat
exchanger and induced draft blower. For proper ue pipe
drainage, the furnace must be level lengthwise from end to
end. The furnace should also be level from back to front or
have a slight tilt with the access doors downhill (approximately
3/4”) from the back panel. The slight tilt allows the heat
exchanger condensate, generated in the recuperator coil, to
ow forward to the recuperator coil front cover.
In horizontal installations with the furnace laying on the left
hand side, the alternate vent connection may be used. In this
conguration the internal elbow is removed. The standard
piping connections may also be used in these positions. Refer
to Vent/Flue Pipe and Combustion Air Pipe section in the
installation instructions for details concerning the conversion
to the alternate vent/ue and combustion air connections on
the 90% furnace.
