This also applies to recirculation mode

if the air is being directed out of the

kitchen.

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 cooker

hood and the heater are in operation

simultaneously, an underpressure of

0.04 mbar (4 pa) is the maximum

permissible in the room.

Ventilation can be maintained by air

inlets which must not be blocked, in

windows, doors and outside wall vents,

or by other technical measures, such

as ensuring that the cooker hood 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

qualified gas fitter (GasSafe

registered in the UK) must be

sought.

Warning and Safety instructions

If the hood is being operated in

recirculation mode and the air is being

directed back into the kitchen, the

above restrictions do not apply.
