Extractors
The operation of appliances that extract
air to the outside (cooker hoods, extrac-
tors, air conditioning units, etc.) can cre-
ate vacuum pressure. If the boiler is
operated at the same time, this can lead
to reverse flow of the flue gas.
Danger
The simultaneous operation of
the boiler and appliances that
extract air to the outside can
result in life threatening poison-
ing due to reverse flow of the flue
gas.
Take suitable steps to ensure an
adequate supply of combustion
air. If necessary, contact your
heating contractor.
