Figures 36 shows the range of venting options using either vertical or horizontal terminations; any layout
that remains within the shaded area is acceptable. Having the fewest number of elbows is ideal as they
tend to disrupt air movement. Using 45˚ elbows is preferable to using 90˚ elbows. Also, a shorter vent
system will perform better than a longer one. The total length of horizontal vent pipe can not exceed 20
feet (6.1m) and the total vent length can not exceed 40ft (12.2m). Any combination of rise and run can be
used as long as it lays within the shaded
area (a total of three (3) 90 ˚ elbows or six
(6) 45 ˚ elbows can be used. In addition
to what is shown, if a 90 ˚ elbow is used
in the horizontal plane, 3 feet (91.4cm)
must be subtracted from the allowable
horizontal run (for each 45 ˚ elbow, 1½
feet (45.7cm) must be subtracted).
Minimum Vent configuration for
rear vent is directly through the exterior
wall behind the fireplace, this would be
approximately 6 - 12”.
Minimum Vent configuration for top
vent is 2’ vertical then directly through
the exterior wall horizontally behind the
fireplace, this would be approximately 9
- 12”.
Maximum Vertical for top or rear
vent is 40’. This is reduced when elbows
are used, see above.
