If the room where the
cooker hood is to be used
contains a fuel burning
appliance such as a central
heating boiler then this
must be of the room
sealed or balanced flue
type.
If other types of flue or
appliance are fitted ensure
that there is an adequate
supply of air to the room.
The cooker hood in fact
could extract the air which
is needed for burning.
When the cooker hood and
appliances supplied with
energy other than
electricity are
simultaneously in
operation the negative
pressure in the room must
not exceed 0,04 mbar in
order to avoid a return of
the gaz emissions.
This is possible through
openings in doors,
windows, or air inlet valves
allowing fresh air to enter
the kitchen.
In any case, in connection
with the discharge of
exhaust air, the
requirements of the
authorities concerned have
to be observed.
Never leave frying pans
unattended during use as
overheated fat and oil may
catch fire.
