the proper ventilation and are not suitable for use with the
cooktop.
Select Hood and Blower Models:
• For wall installations the hood width must, at a
minimum, equal the nominal width of the appliance
cooking surface. Where space permits, a hood larger in
width than the cooking surface may be desirable for
improved ventilation performance.
• For island installations the hood width should, at a
minimum, overhang the appliance cooking surface by
3" on each side.
Hood Placement:
• For best smoke elimination, the lower edge of the hood
should be installed 30" above the appliance cooking
surface. (See Figure 1).
• If the hood contains any combustible materials (i.e., a
wood covering), it must be 36"or greater distance
above the cooking surface.

Important Notes:
• It is recommended that a Thermador Professional wall or island hood or custom insert is used with Thermador
Professional Cooktops.
• Refer to www.Thermador.com for a complete selection of Professional Ventilation options, Blowers, and
Accessories.
• * For high output gas cooktops (60,000 BTU or greater), the minimum of one (1) CFM of ventilation per 100 BTU is
recommended. If the cooktop has a grill or griddle, add 200 CFM to the estimated blower capacity. Add 400 CFM if
the cooktop has a 24" griddle or wok. Additional blower capacity may be required for longer duct runs.
• For island applications, it is recommended to use a hood width that exceeds the width of the cooktop by 6"
(overlapping the cooktop by 3" on each end).
• CFM = "cubic feet per minute" (standard blower capacity rating).

NOTICE:
Most hoods contain combustible components which must
be considered when planning the installation.
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.
NOTE:
Ventilation hoods and blowers are designed for use with
single-wall ducting. Some local building codes may require
double-wall ducting. Before starting installation, consult
local building codes and agencies to insure that the
installation will meet local requirements.
