Figures 29 shows the range of venting options, it shows possible vent confi gurations if the unit is top vented,
for vertical and 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 14 feet (4.27m) and the total vent length can not
exceed 44ft (13.4m). Any combination of
rise and run can be used as long as it lays
within the shaded area (a total of two (2)
90
˚
elbows or four (4) 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 must be subtracted).
Note
: Minimum length of co-linear
venting is 8ft (2.44m) and maximum
length is 40ft (12.19m)
Note
: Minimum length of co-axial venting
with no vertical rise is 7in (25.4mm)
