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 ranges.
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.
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).

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
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. Use a 36" (914mm) minimum
clearance if the hood contains any combustible
materials such as a wood covering (Figure 1 on
page 5).
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.
