4.6 The void into which the appliance is fitted must be ventilated
to prevent a build up of heat. If the void is sealed then it will
be necessary to fit vents at both low and high levels of
approximately 50cm

. These vents should take cold air from
the room and return warm air back into the room.
5. Recessed Installation
This method of installation requires structural alteration to
the intended location. A suitable supporting lintel must be
installed to maintain the structural integrity of the
surrounding blockwork.
5.1 Mark the position of the lintel so that it sits centrally over the
intended installation. Remove the blockwork and install the
lintel using mortar to ensure a strong bond with the
surrounding wall, see Diagram 6.
