Connection to the chimney, choice of the chimney
2.2. CONNECTION TO THE CHIMNEY
Properly calibrated and built chimney is the precondition for a safe operation of the boiler and
economic heating. The chimney has to be good insulated, gas-proof and smooth.
On the lower part of the chimney, a cleaning door has to be built in. Brick layed chimney has to
have 3 layers with an stone wool thermal insulation in the middle. The thickness of the insulation
should be 30 mm, if the chimney is situated inside the building, i.e. 50 mm if the chimney is
situated outside the building. Inside chimney dimensions depend on its height and on the boiler
capacity (Image 1.). The temperature of the flue exhausting gases on their exit point should be
minimum 30°C higher then the temperature of their condensating point. The choice and the
construction of the chimney should be performed by an authorized person.
Maximal distance between boiler and the chimney is 600 mm. In order to unable condensate to
enter from the chimney into the boiler, 10 mm of the flue exhaust tube length has to be insert inside
the chimney. The right choice of the chimney is recommended by the diagram of the image 1. The
boiler can be connected to the chimney from its upper side. Diameter of the chimney connection is
150 mm. For connecting of the boiler to the chimney, there should be used proper tube or knee
fixed to the welded extention
