Important Notes:
It is recommended that a Thermador Professional wall or island hood or custom insert is used with Thermador
Professional Ranges.
The HPWB Professional Series Wall Hoods or the Professional Series Custom Inserts are recommended ventilation
solutions for these ranges. The PH Professional Series Wall Hoods are also a viable option, however the 27" depth of
the PH series may not be suitable to all applications.
Refer to www.Thermador.com for a complete selection of Professional Ventilation options, Blowers, and Accessories.
* For high output gas ranges (60,000 BTU or greater), the minimum of one (1) CFM of ventilation per 100 BTU is
recommended. If the range has a griddle, add 200 CFM to the estimated blower capacity. Additional blower capacity
may be required for longer duct runs.
For island applications, it is recommended to use a hood width that exceeds the width of the range by 6" (overlapping
the range by a minimum of 3" on each end).
**Not all 48" Pro Wall Hood models can accommodate a 1,300 CFM blower option.
CFM = "cubic feet per minute" (standard blower capacity rating).

Step 2: Cabinet Preparation

1. The range is a free standing unit. If the unit is to be
placed adjacent to cabinets, the clearances shown in
Figure 1 are required. The same clearances apply to
island installations, except for the overhead cabinets,
which must have a space wide enough to accept the
flared island hood, as indicated in Figure 1.
2. These ranges may be recessed into the cabinets
beyond the edge of the front face of the oven (See
Figure 2 and Figure 3b).

The maximum depth of over head cabinets installed on
either side of the hood is 13".
A 40-inch minimum clearance is required between the top
of the cooking surface and the bottom of an unprotected
cabinet. A 30-inch clearance can be used when the bottom
of the wood or metal cabinet is protected by not less than
