Using at the same time as other heating appliances that
depend on the air from the room
Danger of poisoning by 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 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.
Cooker hoods draw air in from the room in which they are installed
and from neighbouring rooms. This applies to extraction mode
cooker hoods and to recirculation mode cooker hoods with a
recirculation box located outside the room. If there is insufficient air,
an underpressure will occur. The heating appliance may be starved
of oxygen, impairing combustion. Harmful gases could be drawn
out of the chimney or extraction ducting back into the room, with
potentially fatal consequences.
