5.3.6 Special Conditions Created by Mechanical Exhausting or Fire-
places:
Operation of exhaust fans, ventilation systems, clothes dryers, or fire-
places may create conditions requiring special attention to avoid unsatis-
factory operation of installed gas utilization equipment. Air from Inside
Building. See 5.3.3-a.
VI. INSTALLATION POSITIONS
NOTE: This furnace is shipped from the factory as a Dedicated Upflow.
A "Blocked Drain Kit" (0270K00012) is available and MUST BE USED
if the furnace is installed Horizontal Left or Horizontal Right.
This furnace may be installed in an upright position or horizontal on
either the left or right side panel. Do not install this furnace on its
back. For upright upflow furnaces, return air ductwork may be at-
tached to the side panel(s) and/or basepan. For horizontal upflow
furnaces, return air ductwork must be attached to the basepan. NOTE:
Ductwork must never be attached to the back of the furnace. Contact
your distributor for proper airflow requirements and number of required
ductwork connections. Refer to "Recommended Installation Posi-
tions" figure for appropriate installation positions, ductwork connec-
tions, and resulting airflow arrangements.
VII. HORIZONTAL APPLICATIONS & CONSIDERATIONS
NOTE: This furnace is shipped from the factory as a Dedicated Upflow.
A "Blocked Drain Kit" is available and MUST BE USED if the furnace
is installed Horizontal Left or Horizontal Right. Check the Serial/ Rating
Plate on the furnace for the Kit P/N.

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 appli-
cation of this furnace as a horizontal furnace differs only slightly from
an upright installation. When installing a furnace horizontally, addi-
tional consideration must be given to the following:
ALTERNATE VENT/FLUE

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 clear-
ance of 4 3/4 inches below the furnace must be provided for the drain
trap. Additionally, the appropriate downward piping slope must be main-
tained from the drain trap to the drain location. Refer to Section 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 condensate from freez-
ing.

EVELING
Leveling ensures proper condensate drainage from the heat exchanger
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.

LTERNATE ENT LUE
In horizontal installations provisions for alternate flue piping are avail-
able for upflow furnaces with left discharge. This configuration allows
the flue piping to be run vertically through the furnace. Refer to the
"Recommended Installation Positions" 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 de-
tails concerning the conversion to the alternate vent/flue connections.
When using the horizontal alternate vent configuration, you must use
the RF000142 vent drain kit. See following illustration.
