V-Series Cooktop Hoods
V-Series Cooktop Hoods
Installation Requirements
Ducting:
6” (inch) round, rigid metal duct is recommended for
V- Series cooktop ventilation.
Wall Hoods and Island Hoods include a Backdraft
Damper. Local codes may require use of addition
backdraft damper or make up air.
A straight, short run is most effective and will improve
performance and reduce noise. Elbows, transitions,
and air boxes all reduce performance of hood.
Reducing the duct size less then 6” (inches) for even
a short span reduces air flow for the entire duct run.
Duct run should not exceed 50 feet

. (See Figure 3).
Internal and In-Line blowers require a Roof or Wall
Cap the same duct size as duct run. (See Figure 4).
Contact your local HVAC professional for specific
codes and requirements.
