7.3.1 Burner
pressure
measurement
Using the burner pressure probe, it is possible to measure the pressure on the burner. Connect the probe to the instrument
pressure input and connect to the burner plug. Follow the procedure described in paragraph 8.4 to read the pressure.
7.4 Smoke
measurement
To avoid condensation inside the smoke pump, it 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.
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 shoots by the pump.
Compare the darkening of the filter with the smoke index table. The smoke index found does not exceed the ones defined by
the current normative.
We suggested to use a retaining cone during gas sampling.

do the average calculus.
The smoke measurement requires the instrument in normal operating conditions indicating one of the measured or
calculated parameters. Press [
