Important!
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 damper. Consult local building
codes and/or local agencies, before starting, to ensure that hood and duct installation will meet local
requirements.
Hood blower speeds should be variable to reduce noise and loss of heated or air conditioned
household air when maximum ventilation is not required.
For best smoke elimination, the lower edge of the hood should be installed a minimum of
30" to a maximum of 36" above the range cooking surface (page 15). If the hood contains
any combustible materials (i.e. a wood covering) it must be a minimum of 36" 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.
