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 type of heaters 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.

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.

Separate instructions are supplied with

the external fan.

Before throwing an old appliance

away it must first be made unus-

able. Ensure that disconnection from

the mains supply is carried out by a

competent person and that the cable is

also removed from the appliance to

prevent misuse.

The manufacturer cannot be held lia-

ble for damage caused by non-com-

pliance with these Warning and

Safety instructions.
