J. The flue gas performance measurement must also be
checked at minimum output (see §9.10.2).
IMPORTANT
► Any readings that are out of tolerance
during maximum output cannot be
corrected by adjusting the gas valve.
The boiler must be meticulously
inspected for gas quality / type, correct
components used (especially the gas
restriction ring and the fan including
venturi).
Before measuring the flue gases at minimum output, the
measurement at maximum output must be completed.
See §9.10.1.
The measured CO
2
(H) % at maximum output is
important to determine equilibrium, this must be
completed before checking the minimum output %.
A. Switch on the boiler at minimum output. To do this, tap
simultaneously the Service symbol and the Minus
symbol until the capital letter LL appears on the right
display.
B. Wait until the readout of the flue gas analyser is stable (at
least 10 minutes).
C. Note the measured CO
2
(L) value.
CO

(L) = measured minimum output CO

value
D. Check according to Table 3 whether the measured
minimum output CO
2
(L) value is between the indicated
upper and lower limits.
E. If the minimum output measurement falls outside the limits
given in Table 3a or 3b, continue at §9.10.3 to adjust the
gas valve. If the setting is correct, continue to Step F.
► The CO
2
upper limit is the CO
2
(H) value that
was noted during the maximum output
measurement. (See §9.10.1, Step H)
