Step 1: Ventilation Requirements - Thermador P24WK Installation Instructions Manual

It is strongly recommended that
a suitable exhaust hood be in-
stalled above the appliance.
Downdraft ventilation should not
be used. The table below indi-
cates the Thermador hoods, by
model number, that are recom-
mended for use with the 24" Wok
and 36" and 48" cooktops.
1. Select Hood and Blower Mod-
els:
• For wall installations, the
hood width must, at a mini-
mum, equal the nominal
width of the appliance cook-
ing surface. Where space
permits, a hood larger in width
than the cooking surface may
be desirable for improved
ventilation performance.
• For island installations, the
hood width should, at a mini-

36" COOKTOP
48" COOKTOP
NOTES: * For wall installations where adequate space is available, the installer or user may elect to use
a hood that is wider than the cooktop 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.

mum, overhang the appli-
ance cooking surface by 6"
on each side.
• Hood blower speeds should
be variable to reduce noise
and loss of heated or air con-
ditioned household air when
maximum ventilation is not
required. Normally, the maxi-
mum blower speed is only
required when using the grill.
2. Hood Placement:
• For best smoke elimination,
the lower edge of the hood
should be installed a mini-
mum of 30" to a maximum of
36" above the appliance
cooking surface. (See Fig.
1).
• If the hood contains any com-
bustible materials (i.e., a

wood covering), it must be a
minimum of 36" above the
cooking surface.
3. Consider Make-Up Air:
• Due to the high volume of
ventilation air, a source of
outside replacement air is
recommended. This is par-
ticularly important for tightly
sealed and insulated homes.
• A qualified heating and ven-
tilating contractor should be
consulted.
NOTE: Ventilation hoods and
blowers are designed for use
with single-wall ducting. Some
local building codes may require
double-wall ducting. Before start-
ing installation, consult local
building codes and agencies to
insure that the installation will
meet local requirements.
