room and the adjacent room.
5 The device can be installed if:
▪ 2 ventilation openings are provided between the installation room
and adjacent room (1 each at top and bottom)
▪ Bottom opening: The bottom opening must meet the requirements
for the minimum area of the ventilation opening (VA
as close to the ground as possible. If the ventilation opening starts
on the floor, the height ≥ must be 20 mm. The bottom of the
opening must be ≤100 mm above the floor. At least 50% of the
required minimum area of the ventilation opening (VA
<200 mm from the ground. The entire area of the opening must be
<300 mm from the floor.
▪ Upper opening: The area of the upper opening must be larger or
the same size as the lower opening. The bottom of the upper
opening must be at least 1.5 m above the top edge of the lower
opening.
▪ Ventilation openings to the outside are not considered suitable
ventilation openings.
