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 1 /
4
″ (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.
