HORIZONTAL APPLICATIONS & CONSIDERATIONS

HORIZONTAL APPLICATIONS & CONSIDERATIONS

When using the horizontal alternate vent configuration, you must

 

use the RF000142 vent drain kit. See following illustration.

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 application 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:

DRAINTRAPANDLINES

In horizontal applications the condensate drain trap is secured to the furnace side panel, suspending it below the furnace. A mini- mum clearance of 4 3/4 inches below the furnace must be pro- vided 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 for further de- tails. If the drain trap and drain line will be exposed to temperatures near or below freezing, adequate measures must be taken to pre- vent condensate from freezing.

LEVELING

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, gen- erated in the recuperator coil, to flow forward to the recuperator coil front cover.

ALTERNATEVENT/FLUEANDCOMBUSTIONAIRCONNECTIONS

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. This configura- tion allows the flue and combustion air piping to be run vertically through the side of the furnace. Refer to the “Recommended In- stallation Positions” figure for further detail. The standard piping connections may also be used in these positions. Refer to Vent/ Flue Pipe and Combustion Air Pipe for details concerning the conversion to the alternate vent/flue and combustion air connec- tions.

RecommendedInstallationPositions

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.
