The fuel amount and the amount of combustion air
must be adjusted so that the flame ends
(10 cm) before the rear ceramic screen of the boiler – (the flame must not lick the wall). Under no
circumstances should the flames turn over on the opposite wall. If it happens,
it is necessary to
add combustion air by opening the flap on the burner fan or to decrease fuel dosage
– see the
instructions for use of the ATMOS burner.
If the
flame is, however, too short,
the
flap on the burner fan must be partly closed
or revolutions
of the burner fan must be decreased (S3 parameter). But do not lower the S3 parameter below 60 %.
Recommended values of O
2
in combustion products according to the boiler type:
The excess of oxygen (O
2
) in combustion products is adjusted so that it is in the range from
(7) 8 to 9 (10)% at average CO < 250 mg/m
3
at O
2
ref = 10 (13) %.
This adjustment is optimal for
common practice when the customer combusts various types of pellets with a certain tolerance of
caloric value.
During an authorized measurement of combustion quality performed by chimney sweeper
it is recommended to set the excess of oxygen in combustion products to the minimum value. This is
a general principle that
the lower the excess of oxygen in combustion products the better are the
resulting recalculated values of the measurement.
As for the dust measurement in
combustion products (dust)
, the principles are the same as for
CO measurement
. However, it is necessary to know that precise measurement of the dust is based on
regular cleaning of the measuring instrument immediately after measurement and preferably also before
the following measurement.
Unsufficient cleaning is a frequent problem of these instruments!
ATTENTION – never open the filling or cleaning openings of the boiler during
measurement.
