Harmful gases such as carbon
monoxide could be drawn out of the
chimney or extraction ducting back
into the room with potentially fatal
consequences.
In order to ensure safe operation, and to
prevent gases given off by the heating
appliances from being drawn back into
the room when the extractor and the
heater are in operation simultaneously, an
underpressure in the room of 0.04 mbar
(4 pa) is the maximum permissible.
Ventilation can be maintained by air
inlets which cannot be blocked, in
windows, doors and outside wall vents,
or by other technical measures, such
as ensuring that the extractor can only
be switched on when the heating
appliance is switched off or vice-versa.
A ventilation brick alone is not generally
sufficient to ensure safe ventilation.
The overall ventilation condition of
the dwelling must be taken into
account. If in any doubt, the advice
of a competent builder or, for gas, a
"Corgi" installer, must be sought.
If adequate ventilation can only be
achieved through an open window, a
window contact switch must be fitted.
This ensures that the hood can only be
operated when the window is opened
wide enough.
The advice of a competent builder must
be sought. A window contact switch kit is
available from good builders' merchants.
Take care when ventilating the room
through an open window that ventilation
is not impaired by a closed blind or
curtain.
If the hood is being operated in
recirculation mode, the above
restrictions do not apply.
Before discarding an old
appliance, switch off and
disconnect it from the power supply.
Cut off and render any plug useless.
Cut off the cable directly behind the
appliance to prevent misuse.
This should be done by a competent
person.
The manufacturer cannot be held
liable for damage caused by
non-compliance with these Warning
and Safety instructions.
