Locate 24” x 1/4” tube in bag assembly.
4. Install one end on front cover pressure switch.
5. Route tube to lower port on collector box cover and
cut off excess tubing.
Drain Trap and Lines
In horizontal applications the condensate drain trap is
secured to the furnace side panel, suspending it below the
furnace. A minimum clearance of 5.5” 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
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 freezing.
Leveling
Leveling ensures proper condensate drainage from the
heat exchanger. For proper flue pipe drainage, the furnace
must be level lengthwise from end to end. The furnace
should have a slight tilt from back to front with the access
doors downhill from the back panel approximately 1/2
to 3/4 inches. The slight tilt allows the heat exchanger
condensate, generated in the recuperator coil, to flow
forward to the recuperator coil front cover.

Recommended Installation Positions
Alternate Electrical and Gas Line Connections
This furnace has provisions allowing for electrical and gas
line connections through either side panel. In horizontal
applications the connections can be made either through
the “top” or “bottom” of the furnace.
Drain Pan
A drain pan must be provided if the furnace is installed
above a conditioned area. The drain pan must cover the
entire area under the furnace (and air conditioning coil if
applicable).
Freeze Protection
If the drain line is routed through an area which may see
temperatures near or below freezing, precautions must be
taken to prevent condensate from freezing within the drain
line.
