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 table below indicates the ventilation hood
options and blower capacity guidelines that are
recommended for use with all THERMADOR
NOTICE:
Most range hoods contain combustible components which
must be considered when planning the installation.

* 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" (152mm),
overlapping the range by a minimum of 3" (76mm) on each end.
CFM = "cubic feet per minute" (standard blower capacity rating).

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.
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 a minimum of 3"
(76mm) on each side.
2. Hood Placement:
• For best smoke elimination, the lower edge of the hood
should be installed 30" (762mm) above the range
cooking surface (see "Figure 1: Cabinet Clearances"
on page 5).
• If the hood contains any combustible materials (i.e. a
wood covering), it must be a minimum of 36" (914mm)
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:
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.
