Step 1: Ventilation Requirements - Thermador P24GE Installation Instructions Manual

It is strongly recommended
that a suitable exhaust hood be
installed above the appliance.
Downdraft ventilation should
not be used. The table below
indicates the Thermador hoods,
by model number, that are
recommended for use with the
24" wok, 24" griddle, 30", 36" and
48" cooktops.
Due to the high heat capability
of this unit, particular attention
should be paid to the hood and
duct work installation to assure it
meets local building codes.
Do not install a microwave oven/
ventilator combination above
the cooktop, as these types of
units do not provide the proper
ventilation and are not suitable
for use with the 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
installations having a long duct run or when heavy usage of the grill or wok is anticipated, in
which improved capturing of the cooking exhaust is desired.
** Thermador offers a choice of remote (VTR1030D or VTR1530D) or internal (VTN1030C)
blowers for use in wall installations.
*** Hood models PHH30DS and PHH36DS include a 600-CFM built-in blower. For optimal
ventilation, a hood model with 1000-CFM blower or greater is recommended for cooktops
having a griddle, grill, or wok.

Step 1: Ventilation Requirements

1. Select Hood and Blower
Models:
• For wall installations the
hood width must, at a
minimum, equal the nominal
width of the appliance
cooking 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
minimum, overhang the
appliance cooking surface
by 3" on each side.
2. Hood Placement:
• For best smoke elimination,
the lower edge of the hood
should be installed 36"
above the appliance cooking
surface. (See Fig. 1).
• If the hood contains any

combustible materials (i.e.,
a wood covering), it must be
36" or greater distance 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
particularly important for
tightly sealed and insulated
homes.
• A qualified heating and
ventilating 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
starting installation, consult local
building codes and agencies to
insure that the installation will
meet local requirements.
