Furnace Installation Considerations

The installation of the furnace for a given application will dictate

the position of the furnace, the airflow, ductwork connections,

vent and combustion air piping. Consideration must be given to

the following:

Condensate Trap and Drain Lines

The supplied condensate trap must be attached to the furnace side

panel on either the left or right side. For horizontal installations,

the drain trap is vertically attached to the side panel below the

furnace. A minimum clearance of 6″ (152 mm) below the furnace

is required for the condensate trap. Downward slope of the

condensate drain line from the condensate trap to the drain

location must be provided. Adequate freeze protection of the

drain trap and the drain line must be provided. See “Condensate

Drain Trap” section for further details.

Leveling

Proper leveling of the furnace must be provided to insure proper

drainage of the condensate from the furnace. The furnace must be

level to within

″ (6 mm) from front to back and from side to

side for upflow and downflow installations or top to bottom for

horizontal installations.

Vent and Combustion Air Connections

For venting information literature, contact www.Bryant.com with

the complete model and serial number of the furnace.
On the Dual Certified furnace, the vent and combustion air pipes

attach to the furnace through the top panel for the upflow and

horizontal installations. For the downflow installation, the vent

and combustion air pipes attach to the furnace through the

alternate locations on the furnace side panels.
NOTE: On the Direct Vent furnace, the vent pipe attaches to the
furnace through the side panels. The combustion air pipe attaches
to the top panel or to the alternate location on the side panel.

On the Single Pipe furnace, the vent pipe attaches to the furnace
through the furnace side panels.
NOTE: Repositioning of the combustion blower is required for
the vent pipe connection to the furnace through the “right side”
panel. See “Vent and Combustion Air Piping” section for further
details.

Fig. 3 -- Typical Horizontal Installation

This furnace can be installed horizontally in an attic, basement,

crawl space, alcove, or suspended from a ceiling in a basement or

utility room (See Fig. 3). Do not install furnace on its back as

safety control operation will be adversely affected.
