Step 1: Ventilation Requirements - Thermador PRO-GRAND PD304 Installation Instructions Manual

Step 1: Ventilation Requirements
It is strongly recommended that a
suitable exhaust hood be installed
above the range. Downdraft
ventilation should not be used. The
table below indicates the
Thermador hoods, by model
number, that are recommended
for use with all ranges.
1. Select Hood and
Blower Models:
Forwall 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 sur-
face may be desirable for im-
proved ventilation perfor-
mance.
For island installations, the
hood width should, at a mini-
mum, overhang the range
cooking surface by 3" on each
side.
IMPORTANT:
2. Hood Placement:
Ventilation hoods and blowers are •
designed for use with single wall
ducting. However, some local
building codes or inspectors may
require double wall ducting. Con-
sult local building codes and/or
local agencies, before starting, to
assure that hood and duct instal-
lation will meet local requirements.
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.
For best smoke elimination, the
lower edge of the hood should
be installed a minimum of 30" to
a maximum of 36" above the
range cooking surface. (See
Fig. 1).
If the hood contains any com-
bustible materials (i.e. a wood
covering), it must be a mini-
mum of 36" above the cooking
surface.

Consider Make-Up Air:
Due to the high volume of venti-
lation air, a source of outside
replacement air is recom-
mended. This is particularly im-
portant for tightly sealed and
insulated homes.
A qualified heating and ventilat-
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 (VTRIOOOQ or VTR1400Q) or in-hood (VTNI030C)
blowers for use in wall installations.
