Unit "X" can be installed in room "A" if:
- Two ventilation openings (permanently open) are provided for between room A and B, an upper one

ventilation starts from the floor, height must be at least 20mm. The lower limit of the opening must be
positioned at less of 100mm from the floor. At least 50% of the required opening area must be located
at less than 200mm from the floor.
The whole area of the opening must be located at less than 300mm from the floor.
- Upper opening: The upper opening area must have a length ≥ than/to the one of the lower.The lower
limit of the upper opening must be positioned at least 1,5m above the upper limit of the lower opening.
Ventilation openings towards the exterior are NOT considered suitable (the user may close them when
