1. Maximum allowable limits listed on individual
lengths for inlet and flue and NOT a combination.
2. Minimum requirement for each vent pipe if five (5)
feet in length and one elbow/tee.
3. Tee used in the vent/flue termination must be
included when determining the number of elbows
in the piping system.
4. 2 ½” or 3” diameter pipe can be used in place of 2”
diameter pipe.
5. Increased Clearance Configuration using (2) 45 deg.
Long Sweep elbows should be considered equivalent
to one 90 deg. elbow.
6. One 90° elbow should be secured to the combustion
air intake connection.
Non-Direct Vent (Single Pipe) Piping
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 ex-
tend 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.
Vent/Flue Pipe Terminations
NOTE:
If either a 90 degree or 45 degree elbow is used for
termination, 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
Vent/Flue Pipe and Combustion
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
Vent/Flue Pipe and Com-
bustion Air 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 thickness 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.
NOTE: Terminate both pipes in the same pressure zone
(same side of roof, no major obstacles between pipes,
etc.).
