Secure Installation - Bosch DWB068G50I User Manual And Installation Instructiions

12.4 Secure installation
Follow these safety instructions when installing the appliance.
WARNING ‒ Risk of poisoning!
Risk of poisoning from flue gases being drawn back in. Room-air-
dependent heat-producing appliances (e.g. gas, oil, wood or coal-
operated heaters, continuous flow heaters or water heaters) ob-
tain combustion air from the room in which they are installed and
discharge the exhaust gases into the open through an exhaust
gas system (e.g. a chimney). With the extractor hood switched on,
air is extracted from the kitchen and the adjacent rooms. Without
an adequate supply of air, the air pressure falls below atmo-
spheric pressure. Toxic gases from the flue or the extraction shaft
are sucked back into the living space.
▶ Always ensure adequate fresh air in the room if the appliance is
being operated in exhaust air mode at the same time as a
room-air-dependent heat-producing appliance is being operated.
▶ It is only possible to safely operate the appliance if the pressure
in the room in which the heating appliance is installed does not
drop more than 4 Pa (0.04 mbar) below atmospheric pressure.
This can be achieved whenever the air needed for combustion
is able to enter through openings that cannot be sealed, for ex-
ample in doors, windows, incoming/exhaust air wall boxes or by
other technical means. An incoming/exhaust air wall box alone
does not ensure compliance with the limit.
▶ In any case, consult your responsible chimney sweep. They are
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 appliance is operated
exclusively in circulating-air mode.
