Warning - danger of toxic fumes

Great care should be taken when

using the cooker hood at the same

time and in the same room or area of

the house as another heating appliance

which depends on the air in the room.

Such appliances include gas, oil, wood or

coal-fired boilers and heaters, continuous

flow or other water heaters, gas hobs,

cookers or ovens which draw air in from

the room and duct exhaust gases out

through a chimney or extraction ducting.

When used in extraction mode, with or

without an external motor fitted, the

appliance draws air in from the room in

which it is installed

neighbouring rooms.

If there is insufficient air, an

underpressure will occur. The heating

appliance may be starved of oxygen,

impairing combustion.

Harmful gases such as carbon

monoxide could be drawn out of the

chimney or extraction ducting back

into the room, with potentially fatal

consequences.

from

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

inlets which cannot be blocked, in

windows, doors and outside wall vents,

or by other technical measures, such

as ensuring that the extractor 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

"Corgi" installer, must be sought.
