When using the cooker hood at the
same time as another heating
appliance which depends on the air in
the room (e.g. gas, oil or coal fired
heaters, continuous flow or other water
heaters, gas cooker, gas hob or gas
oven), special care must be taken as
the action of the cooker hood extracts
air from the room in which it is installed
and from neighbouring rooms, which
these type of heaters need for
combustion.
They could also draw exhaust air back
in from chimneys or ducting in
contravention of fire safety regulations.
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.
Note: 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 the cooker hood is operated in
recirculation mode (with a charcoal
filter), the above restrictions do not
apply.
