Thermador Professional PRO-HARMONY PRG30 Manuel D'installation page 5

• 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).

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).
• ** Not all 48" Pro Wall Hood models can accommodate a 1,300 CFM blower option.
• CFM = "cubic feet per minute" (standard blower capacity rating).
Range Top Configuration
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.
