Ventilation Planning Guide
It is recommended that a THERMADOR range, rangetop, and cooktop are used with a THERMADOR hood following the
below approved ventilation combinations for installation.
All blower models referenced may not be compatible with all hoods referenced. Refer to www.thermador.com for a
complete selection of ventilation options, blowers, and accessories.
IMPORTANT NOTES:
• See related Thermador Manuals for additional information.
• Thermador recommends not exceeding 50 ft. (15.24 m) equivalent length of duct.
• Keep duct runs as short and straight as possible. Elbows and transitions fittings reduce air flow efficiency. Back to
back elbows and “S” turns give very poor delivery and are not recommended. A short straight length of duct at the
inlet of a remote blower gives the best delivery.
• For Thermador Professional applications with a non-approved Thermador hood, the hood and/or blower must be
rated for 1 CFM for every 100 BTU on the Range/Rangetop/Cooktop.
• If the range has a 12'' Griddle, add an additional 200 CFM to the estimated blower capacity.
• If the range has a 24'' Griddle, add an additional 400 CFM to the estimated blower capacity.
• If the range has a Grill, add an additional 400 CFM to the estimated blower capacity.
• If the range has a Grill and a Griddle, add an additional 600 CFM to the estimated blower capacity.
• For Thermador Masterpiece applications with a non-approved Thermador hood, the hood and/or blower must be
rated for 1 CFM for every 100 BTU on the Cooktop.
• For Thermador Masterpiece electric and induction applications with a non-approved Thermador hood, the hood
and/or blower must be rated for a minimum of 100 CFM for every lineal foot of the width of the cooking surface.
• For island applications, it is recommended to use a hood width that exceeds the width of the range by 6'' (152 mm),
overlapping the range, rangetop, or cooktop by a minimum of 3'' (76 mm) on each end.
• A 25 foot extension cable (EXTNCB25W) is available for purchase to connect the hood to in-line or remote blowers,
if required.
