Important Notes:
• It is recommended that a Thermador Professional wall or island hood or custom insert is used with Thermador Pro-
fessional Ranges.
• Refer to www.thermador.com for a complete selection of Professional Ventilation options, Blowers, and Accesso-
ries.
• * 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 grill or 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" (overlap-
ping the range by a minimum of 3" on each end).
• CFM = "cubic feet per minute" (standard blower capacity rating).

2. Hood Placement:
• For best smoke elimination, the lower edge of the hood should be installed 36"
above the range cooking surface. (See Figure 1).
• If the hood contains any combustible materials (i.e. a wood covering), it must be
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.
