C. In order to obtain a better combustion and efficiency, all connections on
the flue gas pipe must be sealed. The waste gas pipe should be connected to the chimney in the
shortest way within the dimensions given in the diagram below. Horizontal connections and
equipment such as elbows that reduce traction should be avoided.
A single vertical steel pipe should not be used as a chimney, the chimney should have both an inner
and an outer surface. The outer surface can be steel or brick braided. For the inner surface of the
chimney, corrosion resistant stainless steel can be preferred. In order to prevent condensation,
thermal insulation should be applied to the gap between the inner and outer surfaces of the chimney.
At the lowest level of the chimney, there should be a cleaning cover made of all kinds of sealed steel.
The length of the flue gas pipe between the chimney and the boiler should not exceed one quarter of
the chimney height.
The size of the flue pipe and chimney must be larger than the waste gas outlet (smokehouse)
dimensions of the boiler. The boiler chimney installed should be at least 1 meter above the highest
point of the roof of the space, on flat roofs, and at least 0.4 meters on tiled roofs.
Chimney without flue cap and with flue cap
Wrongly installed flue and correctly installed
flue and flue cap
Nutshells, pellets, etc. When using wood-derived fuels, such as wood-derived fuels, the
fan air should not be opened too much.
Excess air causes high flue temperature and high flue temperature causes loss of
combustion efficiency.
It would be appropriate to take a sample of the fuel you will use in the boiler in bulk, and
if it is suitable for combustion, take the remaining amount. Take care that the sample
you will take is not wet or humid and is pine pellets.
