•
The air supply grilles must be located and installed in a manner that optimizes air
circulation in the rooms.
•
Generally, air distribution must be performed through wall grilles. The air supply
grilles must be located on the upper part of the wall, at least 1 ft. (30 cm) from the
finished ceiling and at least 6 ft. 6 in (2 m) from the floor.
•
It is also possible to distribute air through floor registers. However, floor registers
do not provide as good air circulation as wall grilles, and can be a source of
discomfort for some persons.

•
Generally, air extraction must be performed through wall grilles. The air return
grilles must be installed on the upper part of the wall, at least 1 ft. (30 cm) from the
finished ceiling and at least 6 ft. 6 in (2 m) from the floor.
•
WARNING!
The return grilles cannot be installed less than 10 ft. (3 m) from a
cooking surface. Air extraction from cooking surfaces must be performed by a
range hood.
•
It is also possible to perform air extraction through floor registers. However, floor
registers are prone to capturing debris that could clog the inside of the air return
ducts.

•
Outside hoods must be wall type.
•
All outside hoods which go through the building envelope must:
o
Be hermetically sealed, on their perimeter, to the sealing system they
penetrate.
o
Be equipped with a grid to stop small rodents from entering. This grid must
not be too fine, because it could restrict air from passing through and
become easily clogged with dust.
•
The fresh air intake hood must be located at least 1 ft. 6 in (45 cm) from surfaces
where snow may accumulate and at least 6 ft. (1.80 m) from any exhaust air outlet,
driveways or any other source of contamination.
•
The stale air exhaust hood must be located at least 1 ft. 6 in (45 cm) from surfaces
where snow may accumulate and be equipped with an airtight back draft damper.
•
Whenever possible, the slope of the conduits connecting to the outside hoods
should have a slight slope either towards the outside or the Minotair to drain out
condensates that may form if the airflow passing through the conduits is very
humid.
