Stampa la paginaWhen using the cooker hood at the
same time as another heating ap-
pliance 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, which these types of
heater need for combustion.
They could also draw exhaust air back
in from chimneys or ducting in con-
travention 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 in-
lets which cannot be blocked, in win-
dows, doors and outside wall vents, or
by other technical measures, such as
ensuring that the extractor can only be
switched on when the heating ap-
pliance is switched off or vice-versa.
N.B: The overall ventilation condition of
the dwelling must be taken into ac-
count. If in any doubt, the advice of a
competent builder or, for gas, a "Corgi"
installer must be sought.
For appliances with an external fan
motor fitted (EXT models) the con-
nection of the two units must be made
using the connection cable and the
plug connectors.
Make sure the correct combination of
the two appliances has been selected.
Before discarding an old ap-
pliance 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.
