Page 21: Information For Installation
Information for installation Chimney Information for installation Chimney 7.1.1 Planning and layout Required chimney diameter Please note that in partial-load operation the exhaust temperature is lower and the large chimney diameters, normally used for solid fuel, are no longer ideal. If the cross section is too large, the flue gas no longer safely rises from the chimney opening and may flow along the roof and sink to the windows of the living quarters. - Page 22 Provide a short, ascending flue pipe to the chimney The flue pipe from the boiler to the chimney must be short, leakproof and ascending.
