Calculating the effective length of the exhaust system
For setting up the exhaust system, we recommend a metal pipe of 6'' (15.25 cm) in diameter with a
maximum length of 35 feet (10.7 m). For optimum performance, DO NOT use 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.
