VENTILATION REQUIREMENTS
7
STEP 2:
A suitable exhaust hood must be installed above the cooktop. 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” Cooktop 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. 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 cooktop cooking surface, (step 3 pg. 8). 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 outside replacement air is
recommended. This is particularly important for tightly sealed and insulated homes. A reputable
heating and ventilating contractor should be consulted.
