Calculating Vent System Length
To calculate the length of the system you need, add the
equivalent feet (meters) for each vent piece used in the system.
Vent System
Vent Piece
45° elbow 2.5 ft (0.8 m)
90° elbow 5 ft (1.5 m)
7" (17.8 cm) wall
cap
0 ft (0 m)
Example vent system
1 - 90° elbow = 5 ft (1.5 m)
1 - wall cap = 0 ft (0 m)
8 ft (2.4 m) straight = 8 ft (2.4 m)
System length = 13 ft (3.9 m)
Maximum Recommended Length
7" (17.8 cm) Round Vent = 50 ft (15.2 m)
