3.4 Air
Circulation
Air must flow between the insert and the masonry
, and it is very important that there is a free air supply to the air intakes.
The specified air areas specified in the text are minimum requirements.
Required air vents (circulationg air):
Base:
Minimum 750 cm² free opening.
Hood:
Minimum 1000 cm² free opening.
This is to ensure that heat build-up inside the frame does not become too large and that heat dissipation to the room is suf
fic
ient.
If the house is tight, the room must be equipped with extra fresh air supply e.g. through a separate channel under the fireplac
e.
The fresh air duct should be as straight as possible and made
of non-combustible material.
