• If a 90° elbow is used in the
horizontal vent run, the horizon-
tal vent length is reduced by 36"
(914 mm). See Figure 28. This
does not apply if the 90° elbows
are used to increase or redirect
a vertical rise. See Figure 29.
Example: According to the vent
graph, Figure 27, the maxi-
mum horizontal vent length in a
system with a 7.5' vertical rise
is 20’ (6m) and if a 90° elbow is
required in the horizontal vent it
must be reduced to 17' (5.2 m).
See page 22 “How to Use Vent
Graph.”
In Figures 28 and 29,
graph, Figure 27, the maxi-
mum horizontal vent length in a
system with a 7.5' vertical rise
is 20’ (6m) and if a 90° elbow is
required in the horizontal vent it
must be reduced to 17' (5.2 m).
See page 22 “How to Use Vent
Graph.”
In Figures 28 and 29,
Dimension
A plus B must not be greater than
17' (5.2m).
• The maximum number of 45°
• The maximum number of 45°
elbows permitted per side wall
installation is two (2). These
elbows can be installed in either the vertical or horizontal run.
• For each 45° elbow installed in the horizontal run, the length of the horizontal run
MUST be reduced by 18" (45cm). This does not apply if the 45° elbows are installed
on the vertical part of the vent system.
• The maximum number of elbow degrees in a system is 270°. See Figure 30.

Example:
Elbow 1 = 90°
Elbow 2 = 45°
Elbow 3 = 45°
Elbow 4 = 90°
Total Angular Variation = 270°
