Step 1: Ventilation Requirements - Thermador Professional PRO-GRAND PRD30 Installation Manual

CAUTION:
To eliminate risk of burns or fire caused by
reaching over heated surface units, cabinet
storage located above the surface units should
be avoided.
CAUTION:
When connecting the unit to propane gas, make
certain the propane gas tank is equipped with its
own high-pressure regulator in addition to the
pressure regulator supplied with the range. The
maximum gas pressure to this appliance
must not exceed 14.0 inches water column
(34.9 mb) from the propane gas tank to the
pressure regulator.
CAUTION:
This unit is designed as a cooking appliance.
Based on safety considerations, never use it for
warming or heating a room.
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 on page 4 indicates the ventilation hood
options and blower capacity guidelines that are
recommended for use with all Thermador ranges.
1. Select Hood and Blower Models:
* For wall installations, the hood width must, at a
minimum, equal the width of the range. Where space
permits, a hood larger in width than the range may be
desirable for improved ventilation performance.
* For island installations, the hood width should, at a
minimum, overhang the range by 3" on each side.
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. Consult local
building codes and/or local agencies, before starting, to
assure that hood and duct installation will meet local
requirements.
Do not install a microwave oven/ventilator combination
above the range, as these type of units do not provide the
proper ventilation and are not suitable for use with the
range.
2. Hood Placement:
* For best smoke elimination, the lower edge of the hood
should be installed 30" above the range cooking
surface. (See Figure 1).
* If the hood contains any combustible materials (i.e. a
wood covering), it must be a minimum of 36" above the
cooking surface.
NOTICE:
Most range hoods contain combustible components which
must be considered when planning the installation.
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.
