Step 1 Ventilation Requirements - Thermador PRO-HARMONY P304 Installation Instructions Manual

Step 1 Ventilation Requirements
It is strongJ2: 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:
• Forwailinstallations, thehood
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 desirable for improved ven-
tilation performance.
• For island installations, the
hood width should, at a mini-
mum, overhang the range
cooking surface by 6" on each
side.
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-
suit 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 re-
quired when using the grill.

Hood Placement:
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 sur-
face. (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.

ConsiderMakeoUpAir:
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.

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 (VTRI000Q or VTR1400Q) or in-hood (VTN 1000Q)
blowers for use in wall installations.
