Important information
Danger of death!
Risk of poisoning from flue gases that are
drawn back in.
Always ensure adequate fresh air in the
room if the appliance is being operated in
exhaust air mode at the same time as room
air-dependent heat-producing appliance is
being operated.
Room air-dependent heat-producing appli-
ances (e.g. gas, oil, wood or coal-operated
heaters, continuous flow heaters or water
heaters) obtain combustion air from the room
in which they are installed and discharge the
exhaust gases into the open air through an
exhaust gas system (e.g. a chimney).
In combination with an activated vapour
extractor hood, room air is extracted from the
kitchen and neighbouring rooms - a partial
vacuum is produced if not enough fresh air
is supplied. Toxic gases from the chimney or
the extraction shaft are sucked back into the
living space.
■ Adequate incoming air must therefore
always be ensured.
■ An incoming/exhaust air wall box alone
will not ensure compliance with the limit.
Safe operation is possible only when the
partial vacuum in the place where the
heat-producing appliance is installed does
not exceed 4 Pa (0.04 mbar). This can be
achieved when the air needed for combus-
tion is able to enter through openings that
cannot be sealed, for example in doors,
windows, incoming/exhaust air wall boxes or
by other technical means.
Installation Instructions
In any case, consult your responsible Master
Chimney Sweep. He is able to assess the
house's entire ventilation setup and will sug-
gest the suitable ventilation measures to you.
Unrestricted operation is possible if the
vapour extractor hood is operated exclusively
in the circulating-air mode.
