6.2 Smoke
Measurement
To avoid condensation inside the smoke pump, the pump should aspirate ambient air before the gas sample. This can be
obtained aspirating the air by the fireside (not in the exhaust gas connection pipe) without using the paper filter.
Now place the filter in the pump.
The gas sample should be drawn to the center of the combustion gas flux. The correct gas volume is sampled with 10
uniform shoots by the pump. We suggest to use a retaining cone during gas sampling.
Compare the darkening of the filter with the smoke index comparing table. The smoke index found should not exceed the
ones defined by the current normative.
