Horizontal
Run
Graph 2 shows the maximum horizontal vent run (to the outside wall) for a certain vertical vent rise on Optica and Bioptica models
ONLY. The allowable venting configuration MUST be within the shaded area.
• When using a wall-mounted termination a maximum of
2
horizontally-mounted elbows (45° or 90°) may be used.
- For each 45° elbow, 20”/500
mm
must be subtracted from the horizontal length allowance.
- For each 90° elbow, 40”/1000
mm
must be subtracted from the horizontal length allowance.
• Between 3’3”/1.0
m
and 4’11”/1.5
m
of rise, every increase of 1”/25
mm
allows an increased run of 4”/100
mm
.
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
.
