Step 1: Ventilation
Requirements
It is strongly recommended that a suitable exhaust hood be
installed above the range. Downdraft ventilation should not
be used. The following table indicates the ventilation hood
options and blower capacity guidelines that are
recommended for use with all Thermador ranges.
1. Select Hood and Blower Models:
• For wall installations, the hood width must, at a
minimum, equal the width of the range. Where space
permits, a hood larger in width than the range may be
desirable for improved ventilation performance.
• 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.

Important Notes:
It is recommended that a Thermador Professional wall or island hood or custom insert is used with Thermador
Professional Ranges.
The HPWB or PH Professional Series Wall Hoods or the Professional Series Custom Inserts are recommended
ventilation solutions for these ranges.
Refer to www.Thermador.com for a complete selection of Professional Ventilation options, Blowers, and Accessories.
* For high output gas ranges (60,000 BTU or greater), the minimum of one (1) CFM of ventilation per 100 BTU is
recommended. If the range has a griddle, add 200 CFM to the estimated blower capacity. 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 range by 6" (overlapping the
range by a minimum of 3" on each end).
CFM = “cubic feet per minute” (standard blower capacity rating).
