• For island installations, the hood width should, at a minimum, overhang the range by 3" on each side. 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. Consult local building codes and/or local agencies, before starting, to assure that hood and duct installation will meet local requirements. Do not install a microwave oven/ventilator combination above the range, as these type of units do not provide the proper ventilation and are not suitable for use with the range. 2. Hood Placement: • For best smoke elimination, the lower edge of the hood should be installed 30" above the range cooking surface. (See Figure 1). NOTICE: Most range hoods contain combustible components which must be considered when planning the installation. • If the hood contains any combustible materials (i.e. a wood covering), it must be installed a minimum of 40" above the cooking surface. 3. Consider Make-Up Air: • Due to the high volume of ventilation air, a source of outside replacement air is recommended. This is particularly important for tightly sealed and insulated homes. • A qualified heating and ventilating contractor should be consulted.

For island installations, the hood width should, at a
minimum, overhang the range by 3" on each side.
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. Consult local
building codes and/or local agencies, before starting, to
assure that hood and duct installation will meet local
requirements.
Do not install a microwave oven/ventilator combination
above the range, as these type of units do not provide the
proper ventilation and are not suitable for use with the
range.
2.
Hood Placement:
•
For best smoke elimination, the lower edge of the hood
should be installed 30" above the range cooking
surface. (See Figure 1).
NOTICE:
Most range hoods contain combustible components which
must be considered when planning the installation.
•
If the hood contains any combustible materials (i.e. a
wood covering), it must be installed a minimum of 40"
above the cooking surface.
3.
Consider Make-Up Air:
•
Due to the high volume of ventilation air, a source of
outside replacement air is recommended. This is
particularly important for tightly sealed and insulated
homes.
•
A qualified heating and ventilating contractor should be
consulted.
