Important notes

Ventilation hoods and blowers are designed for use with single wall ducting.
However, some local building codes or inspectors may require double
wall ducting and/or a damper. Consult local building codes and/or local
agencies, before starting, to ensure that hood and duct installation will meet
local requirements.

Semi-rigid ducting is recommended for maximum effectiveness.

Hood blower speeds should be variable to reduce noise and loss of heated or
air conditioned household air when maximum ventilation is not required.
Normally, the maximum blower speed is only required when using the grill.

For best smoke elimination, the lower edge of the hood should be installed a
minimum of 30” (762mm) to a recommened maximum of 42” (1067mm) above
the cooking surface. If the hood contains any combustible materials (eg a wood
covering) it must be a minimum of 36” (914mm) above the cooking surface.

Due to a high volume of ventilation air, a source of make-up air (outside
replacement air) is recommended. This is particularly important for tightly
sealed and insulated homes. A reputable heating and ventilating contractor
should be consulted.
*Recommended maximum.
