ON IRECT ENT INGLE
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-resistant
flashing. For details concerning connection of the vent/flue pipe
to the furnace, refer to Section IX, Vent/Flue Pipe and Combustion
Air - Standard Furnace Connections or Alternate Furnace Con-
nections for specific details. Refer to the following Non-Direct
Vent (Single Pipe) Piping - Vent/Flue Pipe Terminations for spe-
cific details on termination construction.
Although non-direct vent installations do not require a combus-
tion air intake pipe, a minimum of one 90° elbow should be at-
tached to the furnace's combustion air intake if: an upright instal-
lation uses the standard intake location. This elbow will guard
against inadvertent blockage of the air intake.

Refer to the following table for applicable length, elbows, and
4
pipe diameter for construction of the vent/flue pipe system of a
non-direct vent installation. In addition to the vent/flue pipe, a
1
single 90° elbow should be secured to the combustion air intake
to prevent inadvertent blockage. The tee used in the vent/flue
5
termination must be included when determining the number of
elbows in the piping system.

1) One 90° elbow should be secured to the combustion air intake con-
nection.
2) Minimum requirement for each vent pipe is five (5) feet in length and
one elbow/tee.
3) Tees and/or elbows used in the vent/flue termination must be included
when determining the number of elbows in the piping system.
4) 2 1/2" or 3" diameter pipe can be used in place of 2" diameter pipe.
5) Increased Clearance Configurations using (2) 45 deg. Long Sweep
elbows should be considered equivalent to one 90 deg. elbow.

NOTE: If either a 90 degree or 45 degree elbow is used for termi-
nation, it must be pointed downward.
The vent/flue pipe may terminate vertically, as through a roof, or
horizontally, as through an outside wall.
Vertical vent/flue pipe terminations should be as shown in the
following figure. Refer to Section IX, Vent/Flue Pipe and Com-
bustion Air Pipe - Termination Locations for details concerning
location restrictions. The penetration of the vent through the roof
must be sealed tight with proper flashing such as is used with a
plastic plumbing vent.
Horizontal vent/flue pipe terminations should be as shown in the
following figure. Refer to Section IX, Vent/Flue Pipe and Combus-
tion Air Pipe - Termination Locations for details concerning loca-
tion restrictions. A 2 3/8" diameter wall penetration is required for
2" diameter pipe. A 3" diameter hole is required for a 2 1/2" pipe
and a 3 1/2" diameter hole is required for 3" diameter pipe. To
secure the pipe passing through the wall and prohibit damage to
piping connections, a coupling should be installed on either side
of the wall and solvent cemented to a length of pipe connecting
the two couplings. The length of pipe should be the wall thick-
ness plus the depth of the socket fittings to be installed on the
inside and outside of the wall. The wall penetration should be
sealed with silicone caulking material.
In a basement installation, the vent/flue pipe can be run between
joist spaces. If the vent pipe must go below a joist and then up
into the last joist space to penetrate the header, two 45° elbows
should be used to reach the header rather than two 90° elbows.
