Ducting
WARNING
It is important to size the ducting appropriately based on
the instruction below, otherwise damage to the furnace can
occur.
● Ducts 2” or less in diameter should not be factored in the
duct sizing.
● Ducts terminating in dead air spaces with no means for
return air re-circulation should not be counted in the
ducting area.
● Do not install any register within 18” to the return air
opening unless on a wall at 90 degrees to the return air
opening. Never blow the outlet air direct towards the
return air opening.
● Do not install any air booster in the duct system. Such
devices could cause erratic cycle behavior.

Keep all return-air passages clear to allow the furnace to
function properly. Do not block the return airflow path with
ducting.
