(8.3 m) 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. 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.
