Calculating the effective length of the exhaust system
For setting up the exhaust system, we recommend a pipe of 6 '' (15.2 cm) in diameter with a maximum length of 35 feet
(10.7 m). For optimum performance, use no more than three 90° elbows.
To calculate the length of the exhaust system required, add the equivalent length (feet/meters) of all the components used
in the circuit.

1 - 90° Elbow
= 5 ft (1.5 m)
1 - Discharge exit
= 5 ft (1.5 m)
1 - Pipe (straight)
= 9 ft (2.75 m)
Total length
=
19 ft (5.8 m)
