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.
• 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.
• 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 qualified and
trained installer. Local building codes may require the use of make-up 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.
INSTALLATION NOTE: Professional Rangetops and Ranges require that
minimum distances be maintained from the cooking surface to combustible
materials (i.e. a wood covering around the insert). These minimum distances
range from 30" to 36" and can vary from product to product and by
manufacturer. Refer to the installation manual of the rangetop or range
prior to the design and installation of the custom hood insert.

INSTALLATION CONSIDERATIONS
The information in this design guide provides
key features, product dimensions and installation
specifications. Before installing a Thermador Custom
Hood Insert, be sure to verify the dimensions and
electrical connections. Also, always consult with
the installation manual packed with the product for
complete details before installing.
Professional Custom Series Hood Inserts are designed
for installation with all professional-style cooktops
and ranges. Masterpiece
Custom Series Hood Inserts
are designed for installation with non-professional
gas, electric or induction cooktops. Refer to the
appropriate section for additional specifications.
HOOD WIDTH
The hood width should be no less than the width of
the cooking surface. Where space is not restricted, a
wider hood can be used to increase your capture area.
DISTANCE FROM COOKING SURFACE
Proper mounting height is very important. If a hood
is mounted too low, it may be difficult to cook and be
unsafe. If a hood is mounted too high, performance
may be compromised. For optimal performance, the
distance from the cooking surface to the bottom of the
hood should be a minimum of 30", unless otherwise
noted. Please refer to the installation manual for each
hood and cooktop/range model for proper hood
mounting heights.
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 (VTI 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.
