Example (Natural gas G20)
► During maximum output a O
2
(H) value
of 4.0 % has been measured. In that case
the O
2
(L) value at minimum output must
be in-between 4 % (= value O
2
(H) and
6.05% as stated in the table. When during
minimum output a value out of this range
is measured the gas-air ratio must be
adjusted.
IMPORTANT
► The gas air control is correctly set if the
measured value at minimum output falls
within the indicated upper and lower
limits. Adjustment of the gas air control
is not necessary in this case. The setting
at minimum output must be adjusted
using the method described in §8.10.3
if the measured value lies outside the
indicated limits.
E. If the minimum output measurement falls outside the limits
given in Table 3a or 3b, continue at §8.10.3 to set up the
gas valve anew. If the setting is correct, continue to Step F.
F. Mount the front panel and fasten the 2 screws by hand.
Check the CO value at minimum output. The maximum
allowed CO measurement value is 160ppm.
G. Switch on the boiler to maximum output. To do this, hold
the Service button and at the same time tap the Plus
button 2x until the capital letter H appears on the right
display. Check the CO value at maximum output. The
maximum allowed CO measurement value is 160ppm.
H. Switch o the boiler.
I. Remove the analyser probe of the flue gas analyser from the
flue gas measurement point and carefully replace the cap
on the adapter above the boiler.
J. Switch on the boiler again.
K. Check the gas density of the flue gas measurement point.
