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.
NOTE:
Ventilation hoods and blowers are designed for use with
single-wall ducting. Some local building codes may require
double-wall ducting. Before starting installation, consult
local building codes and agencies to insure that the
installation will meet local requirements.

Important Notes:
• It is recommended that a Thermador Professional wall or island hood or custom insert is used with Thermador
Professional Cooktops.
• Refer to www.Thermador.com for a complete selection of Professional Ventilation options, Blowers, and
Accessories.
• * For high output gas cooktops (60,000 BTU or greater), the minimum of one (1) CFM of ventilation per 100 BTU is
recommended. If the cooktop 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 cooktop by 6”
(overlapping the cooktop by 3” on each end).
• **Not all 48” Pro Wall Hood models can accommodate a 1300 CFM blower option.
• CFM = “cubic feet per minute” (standard blower capacity rating).
