Fig.G.17: Soot raiting
Determine the soot rating with a soot pump (1)
and soot rating reference scale. The figure
should not exceed "1". Otherwise, open the air
flap (Fig.G.07) a little and repeat the measure-
ment. Repeat the procedure until the specified
value is obtained.

Fig.G.18: Burner measurements.
The CO2 content in the exhaust, the intake
and exhaust temperature are determined. This
can be done with conventional meters or, as in
Fig. G.08, with an electronic meter like the
TESTO 327 (4), which measures and displays
all relevant data.
If the measured value is too low, close the air
flap (Fig.G.06) a little and check the soot rating
and Co2 content again.
