The room containing the oven should have an air supply in accordance with BS.5540:
Part 2: 1989.
All rooms require an openable window or equivalent while some rooms require a perma-
nent vent in addition to the openable window.
The oven should not be installed in a bed-sitting room, of volume less than 21 m

Where a DOMESTIC OVEN is installed in a room or internal space, that room or internal
space shall be provided with a permanent opening which communicates directly with out-
side air and is sized in accordance with table below. In domestic premises the permanent
opening shall be an air vent.
If there are other fuel burning appliances in the same room, BS.5540: Part 2: 1989 should
be consulted to determine the requisite air vent requirements.

Provison for ventilation
Also ensure that the front rail at the top of the unit is not installed as it could
restrict ventilation.
If the oven is being built in to a kitchen unit (fig. 2.2) ensure that the oven is ventilated
with a 50 mm space at the top of the kitchen unit.
Failure to allow adequate ventilation to the appliance may result in over heating or dam-
age to adjacent units.
Lift the oven carefully into position on the shelf, taking care NOT to lift it by the door
handle. If you lower the oven door, you will see 4 screw holes, 2 on each side of the
oven.
The oven should then be secured to the housing by fitting screws into these holes.
Remember the housing should not be free standing but secured to the wall and/or
adjacent fittings.
