The boiler draws combustion air from the living space via a coaxial
pipe with ventilation air apertures upstream of the shaft inlet and expels
the flue gas either via a flue pipe or via a moisture-resistant chimney
through the roof (combustion air supply via interconnected rooms
according to TRGI).
