ENERAL
Horizontal applications, in particular, may dictate many of the
installation's specifics such as airflow direction, ductwork connec-
tions, flue and combustion air pipe connections, etc. The basic ap-
plication of this furnace as a horizontal furnace differs only slightly
from an upright installation. When installing a furnace horizontally,
additional consideration must be given to the following:

RAIN RAP AND INES
In horizontal applications the condensate drain trap is secured to the
furnace side panel, suspending it below the furnace. A minimum
clearance of 4 3/4 inches 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 Sec-
tion X, Condensate Drain Trap and Lines 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 con-
densate from freezing.
NOTE: The use of insulation and/or heat tape is recommended.
Failure to provide proper condensate drainage can result in property
damage.
L
EVELING
Leveling ensures proper condensate drainage from the heat ex-
changer and induced draft blower. For proper flue 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 inches) from the back panel.
The slight tilt allows the heat exchanger condensate, generated in
the recuperator coil, to flow forward to the recuperator coil front cover.
A V /F
LTERNATE ENT LUE AND
In horizontal installations provisions for alternate flue and combus-
tion air piping are available for upflow furnaces with left discharge
and counterflow furnaces with right air discharge. In these positions
the flue and combustion air piping can be run vertically through the
side of the furnace. Refer to the "Recommended Installation Posi-
tions" figure for further detail. The standard piping connections may
also be used in these positions. Refer to Section IX, Vent/Flue Pipe
and Combustion Air Pipe for details concerning the conversion to
the alternate vent/flue and combustion air connections.

Recommended Installation Positions
NOTE: Alternate "vertical" piping connections can not be used when
an upflow furnace is installed with supply air discharging to the right,
or when a counterflow furnace is installed with supply air discharging
to the left. In either case, use the standard flue and combustion air
piping connections.
A E
LTERNATE LECTRICAL AND
This furnace has provisions allowing for electrical and gas line con-
nections through either side panel. In horizontal applications the
connections can be made either through the "top" or "bottom" of the
furnace.
D P
RAIN AN
A drain pan must be provided if the furnace is installed above a con-
ditioned area. The drain pan must cover the entire area under the
furnace (and air conditioning coil if applicable).
F P
REEZE ROTECTION
Refer to Section VI, Horizontal Applications and Conditions - Drain
Trap and Lines.
F S
URNACE USPENSION
If the furnace is installed in a crawl space it must be suspended from
the floor joist or supported by a concrete pad. Never install the fur-
nace on the ground or allow it to be exposed to water. Refer to
Section IV, Location Requirements and Considerations - Furnace
Suspension for further details.

This furnace is shipped from the factory configured for natural gas at
standard altitude. Propane gas installations require an orifice change
to compensate for the energy content difference between natural
and propane gas.
