Warning!
Material damage and injury due to incorrect chimney sweep test
The chimney sweep test requires comprehensive technical know-
ledge.
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 is sufficient heating demand placed on
the heating circuit.
The chimney sweep measurement must be performed when opera-
ting at full load. (It is absolutely essential to avoid the heating up
and burning out phases.) Having the measurement repeated by the
combustion engineer or by HDG specialists will incur charges.
