Safe operation is possible provided the low
pressure in the installation room of the heating
appliance does not exceed 4Pa (0.04mbar).
This can be achieved if the combustion air can
ow through non-closable openings, e.g. in
doors, windows, in conjunction with air
intake/exhaust air wall boxes or by other
technical measures.
Adequate intake air must therefore always
be provided.
An intake/exhaust air wall box alone does not
ensure compliance with the limit value.
NOTE: When making your evaluation, always
consider the entire ventilation system in the
home. Include the advice of a competent
heating engineer when making your
evaluation.
If the extractor hood is used in circulating
air mode only, it can be operated without any
restrictions.
Special information for gas cookers
When installing the extractor hood above
gas hobs, observe the appropriate national
statutory regulations (e.g. in Germany:
Technische Regeln Gasinstallation TRGI).
Observe the currently valid installation
regulations and instructions of the gas
appliance manufacturer.
During installation, ensure that only one side
of the extractor hood is situated directly next to
a high-sided unit or a wall. Otherwise, there is a
risk of heat build-up. The gap between the
extractor hood and the wall or high-sided unit
must be at least 50 mm.
ṇ RISK OF BURNS
Do not operate more than 2 gas cooking areas
simultaneously over a period of max.
15 minutes at maximum thermal load. Due to
the eect of the heat there is a risk of burns if
the surfaces of the housing are touched!
Note that one large burner of more than
5 kW (Wok) is equivalent to the power of 2 gas
burners.
The extractor hood may be damaged by
the intense heat.
Never operate a gas cooking area without a
cooking utensil on it. Regulate the ame in
such a way that it does not project over the
cooking utensil.
