PLANNINg INFORMATION
CHOOSINg THE RIgHT CFM
The power of the cooktop or range, measured in BTU, is perhaps the most
important factor in determining CFM needs for a hood. Professional gas
cooktops generally should have 1 CFM for every 100 BTU. For Masterpiece
Electric and Induction Cooktops, and Gas Cooktops under 60,000 BTU,
choose a blower with a minimum of 100 CFM per 12" of cooktop width.
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.
• 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.
• For those who are used to preparing quick meals in a relatively small
kitchen, a hood with 400 to 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.
LENgTH AND SIzE OF DUCTWORK
Proper performance is dependent upon proper ducting. Use a qualified and
trained installer.
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.
Local building codes may require the use of makeup air systems when using
ducted ventilation systems greater than specified CFM of air movement. The
specified CFM varies from locale to locale. Consult your HVAC professional
for specific 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.

AVAILABLE CEILINg HEIgHT
The standard ceiling height can vary from region to
region and in homes built in different eras. Ceiling
heights, even in the same room, can sometimes vary
by as much as several inches. Kitchen ceiling heights
can vary between 7'6" (or 90") to over 10' (or 120").
Before selecting your hood, check your available
installation space and any extra space that may remain
after proper installation of your hood and cooktop or
range. This extra space can be filled using Thermador‘s
Stainless Steel Duct Cover or Chimney Extension
Accessories. The space can also be adjusted by raising
or lowering your hood within the recommended range
(typically 30" to 36" above the cooking surface).
CHOOSINg THE CORRECT BLOWER
A variety of interior and exterior blower options
(Remote, Inline or Integrated) are available for
Thermador’s Professional and Masterpiece
®
Series
Hoods. If the unit you have selected does not have
a blower included, one can be purchased separately.
Blower selection will vary based on the volume of air
that needs to be moved and the length and location
of the duct run. For long duct runs with multiple turns
and bends, consider using a more powerful blower. For
the most efficient air flow exhaust, use a straight run or
as few elbows as possible.
Remote Blowers (VTR Series)
Depending on your preference and ducting situation,
these blowers can be mounted on the roof or exterior
wall of your home. An exterior installation may be
more appealing to reduce noise in the kitchen.
Inline Blowers (VTI series)
To minimize noise in the kitchen, these blowers are
mounted along the duct line anywhere between the
kitchen and the exterior wall. If you have easy access
to your duct line (in an attic, for example), this may be
an appealing option.
Integrated Blowers (VTN series)
These blowers are purchased separately and
integrated into the hood or onto the downdraft unit at
the time of installation. This option allows you to select
your ideal hood with the exact power you require.
SPECIAL NOTE:
Always allow access to the blower for
serviceability, should it be needed.
