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 on page 4 indicates the ventilation hood
options and blower capacity guidelines that are
recommended for use with all THERMADOR
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.
Due to the high heat of the rangetop burners, 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.
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/rangetop
may be desirable for improved ventilation performance.
• For island installations, the hood width should
overhang the width of 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).
• If the hood contains any combustible materials (i.e. a
wood covering), it must be installed a minimum of 36"
(914mm) above the cooking surface (see Figure 1).
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.
