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 airflow of 600 to 1,300 CFM.
• or 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 flexible 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 quali ed and trained installer. Local
building codes may require the use of make-up
air systems when using ducted ventilation systems
greater than speci ed CFM of air movement. The
speci ed CFM varies from locale to locale. Consult
your HVAC professional for speci c 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.
