VENTILATION REQUIREMENTS
A suitable exhaust hood must be installed above the range. The following chart indicates the
minimum blower capacity recommended for hood ventilation.
* When installing a unit featuring a grill, select a blower on the high end of recommendation.
** For all 36”& 48” Range GL models a 1200 CFM ventilation unit is required.
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 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.
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 11 & 12). 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 is recommended. This is particularly
important for tightly sealed and insulated homes. A reputable heating and ventilating contractor
should be consulted.
