Table 1. Ventilator performance calculation

Us e this chart to compute maximum permissable lengths for duct runs to outdoors .

Note: Do not exceed maximum permissable equivalent lengths!

Maximum recommended duct length for these hoods: 150 feet

Flexible ducting:

If flexible metal ducting is used, all the equivalent f eet values in the table should be doubled. The flexible metal duct shou ld be straight and smooth and extended as much as possible.

Do NOT use flexible plastic ducting.

Note: Any home ventilation system, such as a

gas furnaces, gas water heaters and other naturally vented systems. To minimize the chance of interruption of such naturally vented systems, follow the heating equipment manufacturer’s guidelines and safety standards such as those published by NFPA and ASHRAE.

*Hoods are supplied with a 10" round transition. A locally supplied transition is required for other sizes.

Note: Outlet on top of hood is 8-1/8" x 8".
