HORIZONTAL TERMINATIONS
Graph 1 shows the maximum horizontal vent run (to the outside wall) for the corresponding vertical vent rise. The allowable
venting configuration MUST be within the shaded area. Power vent systems are available for configurations outside of the shaded
area.
• When using a wall-mounted termination, a maximum of
3
elbows (45° or 90°) may be used.
- For any additional 45° elbow, 20”/500
mm
must be subtracted from the horizontal length allowance.
- For any additional 90° elbow, 40”/1000
mm
must be subtracted from the horizontal length allowance.
Example A: With a total rise of 60”/1.52
m
and one horizontal 90° elbow, a total run of 13’1”/4.0
m
is allowed
Example B: If the rise is 3’10”/1168
mm
then the run can be no longer than 12’/3.67
m.
Example C: If the run is 5’ 6”/1.68
m
then the rise must be at least 2’2”/670
mm
.
