The alternate vent/flue location is the large hole directly in line with the induced draft blower outlet. To use the alternate vent/flue
location refer to the following steps and the "Alternate Vent/Flue Location" figure.
NOTE: In the horizontal left installation position, a means of
condensate collection must be provided to keep vent pipe con-
densate from entering the draft inducer housing. If the vent
drain elbow is eliminated from the installation, an RF000142
kit must be used.
1. Remove the four screws from the vent pipe flange on top
the furnace.
2. Remove the internal elbow and vent pipe
3. Cut 2 1/2" from the flange .

When using the alternate venting location, either in a horizontal left side down installation or a vertical installation using
down – venting, an alternate combustion air opening can be used. A locating dimple is located on the right side of the
furnace cabinet. The locating dimple is 1 7/8" measured from the front edge of the cabinet in line with the knock out. To
use the alternate combustion air location:
1. Remove screws and combustion air flange from cabinet.
2. Insert cabinet plug in unused combustion air hole.
3. Drill a pilot hole at the cabinet dimple (size dictated by
knockout tool used).
4. Use a knockout tool to create a 3" diameter hole
5. Install combustion air flange and secure with screws
removed in step one.
