Step 1: Ventilation Requirements
Itisstronglyrecommendedthat
a suitable exhaust hood be in-
stalled above the range.
Downdraftventilationshouldnot
be used. The table below indi-
cates the Thermador hoods, by
model number, that are recom-
mended for use with all ranges.
1. Select Hood and
Blower Models:
• For wall installations, the hood
width must, at a minimum, equal
the width of the range cooking
surface. Where space permits, a
hood larger in width than the
cooking surface may be desir-
ableforimprovedventilationper-
formance.
•Forislandinstallations,thehood
widthshould,ataminimum,over-
hang the range cooking surface
by 6" on both sides.
CAUTION:
Ventilationhoodsandblowersare
designed for use with single wall
ducting. However, some local
buildingcodesorinspectorsmay
requiredoublewallducting.Con-
sult local building codes and/or
localagencies,beforestarting,to
assure that hood and duct instal-
lation will meet local require-
ments.
• Hood blower speeds should be
variable to reduce noise and loss
of heated or air conditioned
household air when maximum
ventilation is not required. Nor-
mally,themaximumblowerspeed
is only required when using the
grill.
2. Hood Placement:
•Forbestsmokeelimination,the
loweredgeofthehoodshouldbe
installed a minimum of 30" to a
maximumof36"abovetherange
cooking surface. (See Fig. 1).
• If the hood contains any com-
bustible materials (i.e. a wood
covering), it must be a minimum
of36"abovethecookingsurface.
3.ConsiderMake-UpAir:
• Due to the high volume of ven-
tilation air, a source of outside
replacementairisrecommended.
This is particularly important for
tightly sealed and insulated
homes.
•Aqualifiedheatingandventilat-
ing contractor should be con-
sulted.

Notes: * For wall installations where adequate space is available, the installer or user may elect to
use a hood that is wider than the range cooking surface. This may be particularly
beneficial for those cases, such as a long duct run or heavy usage of the grill, in which
improved capturing of the cooking exhaust is desired.
** Thermador offers a choice of remote (VTR1000Q or VTR1400Q) or in-hood (VTN1000Q)
blowers for use in wall installations.
