Alternate installations with concrete slab
Venting systems can be routed under slabs of concrete. The
exhaust may go through the wall or into a window well.

Determine vent length
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.
NOTE: Maximum equivalent length is 60 ft (18.3 m).

Example calculation
Vent Part Length
90 ° elbows (3) 15 ft (4.6 m)
12 ft (3.7 m) straight vent 12 ft (3.7 m)
Wall cap 0 ft (0 cm)
Total amount* 27 ft (8.3 m)
*Equivalent length for 6" (15.2 cm) round venting.
NOTE: Flexible metal vent is not recommended, if such parts are
used, calculate each 1 ft (30 cm) of flexible vent as 2 ft (61 cm) of
straight metal vent. Flexible metal elbows count twice as much
as standard elbows.
