Power Supply
Safety
This downdraft vent must be supplied with 120V, 60Hz., and connected to an individual, properly grounded branch circuit, protected by a 15 or 20 ampere circuit breaker or time delay fuse.
Gas Cooktops
Do not leave gas or electrical connections within shaded area.
Instructions
If this vent is installed in combination with a gas cooktop, it may operate from the same duplex outlet.

Ductwork Length and Dust Fittings
NOTE: Do not exceed 150′ maximum permissible equivalent lengths!
Flexible ducting: If flexible metal ducting is used, all equivalent feet values in the table should be doubled. The flexible metal duct should be straight and smooth and extended as much as possible.
DO NOT use flexible plastic ducting.
Add equivalent lengths for all duct pieces and transitions used to ensure that the duct run does not exceed the maximum 150′.
