Warning!
Material damage and injury due to incorrect chimney sweep test
The chimney sweep test requires comprehensive technical
knowledge.
Only permit authorised specialists to perform the chimney sweep
test.
At the start of the measurement, the boiler temperature should not
exceed 75°C. If there is an accumulator, its temperature should not
exceed 60°C. Ensure there that the heating circuit has sufficient
heat transfer capacity.
The chimney sweep measurement must be performed when
operating at full load. (It is absolutely essential to avoid the heating
up and burning out phases.) Having the test repeated by the
combustion engineer or by HDG specialists will incur charges.
