If a 90° elbow is used in the horizontal vent run, the horizontal
vent length is reduced by 36" (914 mm).
Figure 24.
This does
not apply if the 90° elbows are used to increase or redirect a
vertical rise.
Figure 24
example:
According to the vent graph,
Figure 21
, the maximum
horizontal vent length in a system with a 7.5' vertical rise is 0’
(6 m) and if a 90° elbow is required in the horizontal vent it must
be reduced to 17' (5. m). Refer to Page 19 “How to Use Vent
Graph.”
In
Figures 25 and 26
, Dimension A plus B must not be greater
than 17' (5. m).
•
The maximum number of 45° elbows permitted per side wall
installation is two (). 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" (45 cm). 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 70°.
