To avoid condensation inside the smoke pump, aspirate ambient air
before the gas sample by the fireside (not in the exhaust gas connection
pipe) without using the paper filter. Introduce now 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 suctions from the pump.
Compare the darkening of the filter with the smoke index table.
The smoke index found cannot exceed the ones defined by the current
normative.
We suggested to use a retaining cone during gas sampling.
