VENTING REQUIREMENTS
Vent system can terminate either through the
roof or wall. Use 7" (17.8 cm) round vent with a
maximum length of 50 ft (15.2 m) for vent system.
NOTE
Flexible vent is not recommended.
Flexible vent creates both back pressure
and air turbulence that greatly reduce
performance.

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.
It's important to note that the actual equivalent
length can vary depending on factors design,
material and any internal obstructions within
the fitting. This is a general guideline, and other
sources may provide slightly different values
Manufacturer data and engineering references
should always be consulted for accurate and up
to date information on the equivalent length of a
specific fitting.
