To Determine Equivalent Vent Lengths, Add:
8" Common Vent
87 Degree Elbow 5.0' (1.5m)
45 Degree Elbow 2.5' (0.8m)
• The vent termination does not count as part of the
straight pipe equivalent when determining the total
vent length.
• The system may be vented horizontally through a
wall or vertically through the roof.
• Header kits have already been counted and do not
need to be added.
