When using the alternate venting location, either in a hori-
zontal 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" mea-
sured 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.

Non-direct vent installations require only a vent/flue pipe. The
vent pipe can be run horizontally with an exit through the side of
the building or run vertically with an exit through the roof of the
building. The vent can also be run through an existing unused
chimney; however, it must extend a minimum of 12 inches above
the top of the chimney. The space between the vent pipe and the
chimney must be closed with a weather-tight, corrosion-resis-
tant flashing.
Although non-direct vent installations do not require a combus-
tion air intake pipe, a minimum of one 90° elbow should be
attached to the furnace's combustion air intake if: an upright
installation uses the standard intake location, or a horizontal
installation uses the alternate air intake location. This elbow will
guard against inadvertent blockage of the air intake.
