The stack is terminated above the roof finish with a tile/slate external roof ventilator. The reception sump may service up to 250m2 floor area, positioned in the most central location to promote even/optimum evacuation. Inhalation apertures and inlet/outlet portholes permit spur connection to adjoining sumps or horizontal extraction should the size or layout of the property dictate.
