When 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) spe-
cial 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 contra-
vention of fire safety regulations.
In order to ensure safe operation, and
to prevent gases given off by the heat-
ing appliances from being drawn back
into the room when the extractor and
the heater are in operation simulta-
neously, 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 appli-
ance 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.
If the cooker hood is operated in
recirculation mode the above
restrictions do not apply.
Appliances with external fans
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.
Disposal of your old appliance
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 di-
rectly behind the appliance to prevent
misuse.
This should be done by a competent
person.
The manufacturer cannot be held lia-
ble for damage caused by non-com-
pliance with these Warning and
Safety instructions.
