FEATURES & BENEFITS
CHOOSING THE RIGHT CFM
The power of the cooktop, measured in BTU, is perhaps
the most important factor in determining CFM needs for
a hood. Professional Gas Rangetops generally should
have 1 CFM for every 100 BTU.
You should also consider the cooking space and cooking
style of your client.
• More demanding cooks usually require more exhaust
capacity to handle moisture generated by boiling large
pots of water or the grease and smoke resulting from
grilling or frying. This cooking style could require a hood
or downdraft system with airow of 600 to 1,300 CFM.
• For those who are used to preparing quick meals in a
relatively small kitchen, a hood with 600 CFM may be
adequate ventilation for the cooking space.
• If the cooking surface is in a peninsula or island, a larger
capacity hood can provide better capture when there
are cross currents and when the hood needs to be
mounted higher. Downdraft ventilation systems are also
a good alternative.
• High heat cooking or aromatic foods may require
additional CFM. Increasing capture area by 3" on each
side is also a recommended way to address this issue.
LENGTH AND SIzE OF DUCTWORK
Do not use exible duct; it creates back pressure/air
turbulence and reduces performance.
Straight runs and gradual turns are best. Use the shortest
route with the fewest turns possible.
Proper performance is dependent upon proper ducting.
Use a qualied and trained installer. Local building codes
may require the use of make-up air systems when using
ducted ventilation systems greater than specied CFM
of air movement. The specied CFM varies from locale
to locale. Consult your HVAC professional for specic
requirements in your area.
If using a 10" duct, Thermador recommends not
exceeding 150 feet of duct. Transitions, elbows and
wall or roof caps are all factors that will add more static
pressure, therefore increasing your equivalent duct run.
