Step 1: Ventilation Requirements - Thermador PRG304EG Installation Instructions Manual

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:
• 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 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.

* For wall installations where adequate space is available, the installer or user may elect to
Notes:
use a hood that is wider than the rangetop cooking surface. This may be particularly beneficial
for installations having a long duct run or when heavy usage of the grill 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.

Step 1: Ventilation Requirements

IMPORTANT:
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.
Do not install a microwave oven /
ventilator combination above the
range, as these types of units do
not provide the proper ventilation
and are not suitable for use with
the range.

2. Hood Placement:
• The lower edge of the hood
should be installed a minimum
of 36" above the range cook-
ing surface. Also use a 36"
minimum clearance if the hood
contains any combustible
materials such as a wood cov-
ering. (See Figure 1).
3. Consider Make-Up
Air:
• Due to the high volume of ven-
tilation air, a source of outside
replacement air is recom-
mended. This is particularly
important for tightly sealed and
insulated homes.
• A qualified heating and venti-
lating contractor should be
consulted.
