Total equivalent vent system length
Determine equivalent length of vent. Maximum
equivalent length of vent is 60 ft (18.3 m).
List the number of each piece and length of straight vent you will use.
Multiply the equivalent length by the number of pieces. Add the totals
to get the total equivalent length of your system.

into rating for maximum vent system length. A suitable wall/roof
cap must be used.

Note: Flexible metal vent is Not recommended.
If it is used, calculate each foot (30 cm) of flexible vent
as two feet (61 cm) of straight metal vent. Flexible
metal elbows count twice as much as standard elbows.
90° elbows (3) = 15 ft. (4.6 m)
12 feet (3.7 m) straight = 12 ft. (3.7 m)
