1) Maximum allowable limits listed on individual lengths for inlet and flue and NOT
a combination.
2) Minimum requirement for each vent pipe is 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 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.
6) One 90° elbow should be secured to the combustion air intake connection.

Vent/Flue and Combustion Air Pipe Lengths and
(6
Diameters
Refer to the preceding table for applicable length, elbows,
and pipe diameter for construction of the vent/flue and
7 8
combustion air intake pipe systems of a non-direct vent
(single pipe) installation. The number of elbows tabulated
86 82
94 89
represents the number of elbows and/or tees in each (Vent/
25 20
Flue & Combustion Air Intake) pipe. Elbows and/or tees used
85 78
in the terminations must be included when determining the
N/A N/A
number of elbows in the piping systems.
30 23
N/A N/A If the combustion air intake pipe is to be installed above a
30 23
finished ceiling or other area where dripping of condensate
10 5
will be objectionable, insulation of the combustion air pipe
30 23
may be required. Use 1/2" thick closed cell foam insulation
30 25
such as Armaflex or Insultube where required.

Vent/Flue Pipe Terminations
N/A N/A
The vent/flue pipe may terminate vertically, as through a roof,
23 16
or horizontally, as through an outside wall.
7 8
Vertical vent/flue pipe termination should be as shown in the
52 48
following figures. Refer to Vent/Flue Pipe and Combustion
94 89
15 10
Air Pipe - Termination Locations section in this manual or
126 119
the installation instructions for details concerning location
5 N/A
restrictions. The penetration of the vent through the roof must
126 119
be sealed tight with proper flashing such as is used with a
30 25
71 64
plastic plumbing vent.
15 10
NOTE: Terminate both pipes in the same pressure zone
78 71
(same side of roof, no major obstacles between pipes,
10 5
etc.).
