Calculating Vent System Length

IMPORTANT: This range is rated at 60 ft (18.3 m) of straight duct.
Low range is up to 30 ft (9.1 m); high range is 31 ft (9.4 m) to
60 ft (18.3 m).
If equivalent duct length exceeds 30 ft (18.3 m), the blower must
be converted to high range.
Do not convert to high range for shorter lengths. This will
cause excessive noise, conditioned air loss and affect the
flame pattern on gas ranges.

To convert blower for high range installations, see the
"Install Downdraft System" section.
To calculate the length of the system you need, add the equivalent
feet (meters) for each vent piece used in the system.
