When using the horizontal alternate vent configuration, you must
use the RF000142 vent drain kit. See “Alternate Flue/Vent
Location” illustration.
NOTE: Alternate vertical piping connections cannot be used
when an upflow furnace is installed with the supply air
discharging to the right, or when a counterflow furnace is
installed with the supply air discharging to the left. In either case,
use the standard flue and combustion air piping connections.

NOTES:
■
The field supplied drain hose is connected from the vent/
drain connection to the condensate drain line with a field
supplied connector.
■
Make a small loop in the drain hose to serve as a P-trap.
