Warning and Safety instructions

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 simultan-

eously, 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 or outside wall vents, or by other tech-

nical 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 (registered with an official gas safety body

in accordance with national safety regulations, GasSafe in the UK)

must be sought.

If the cooker hood is used in recirculation mode, where the air is

directed back into the room in which it is located, operating a heat-

ing appliance which depends on the room air at the same time is

no cause for concern.
