Upflow Furnace with Two Side Returns
Important: One of the sides must have a transition to allow the
condensate and thermostat wiring to exit the cabinet.
Important: If a transition is not a viable option, a hole may be drilled
in the bottom of the cabinet to allow the condensate to
exit. Also, a hole will need to be drilled in the side of the
cabinet for the thermostat wiring to exit.
Important: Make sure not to cut the cabinet in the "No Cut" area.
Note: If using one transition, the condensate and thermostat wiring
will exit on the transition side.
Note: If using a filter boxes, use transitions, if possible, to attach the
filter boxes to the furnace cabinet. If transitions are not used,
condensate may exit through the bottom of the furnace.
