VENTILATION REQUIREMENTS

A suitable exhaust hood must be installed above the range. The following chart indicates the minimum blower
capacity recommended for hood ventilation.
Ventilation Unit
* 36" ranges featuring a grill (GL models) require a 1200 CFM ventilation unit
CAUTION:
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.
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 or the self-cleaning cycle.
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, (see section 'Cabinet Preparation'). If the hood contains any combustible
materials (e.g. 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.
