6.8 - Measurement and
adjustment of CO2 levels
The appliance in normal operating mode and for altitudes within
1000 m, must have a CO2 (carbon dioxide) level in the exhaust
flue gases within the parameters as detailed in paragraph 9. A value
which is different to those detailed can cause malfunctions and is
strictly prohibited. Combustion analysis must be performed to check
and eventually adjust this value. Proceed as follows:
1.- check a combustion analyser to the appropriate point on
the fumes exhaust fitting “B” in figure 6.13;
2.- open the domestic hot water tap fully;
3.- wait for the CO2 measurement to stabilise;
4.- compare the value measured with that given in the
table in figure 6.7, “CO2 maximum power”. If the value
measured is offset from the value read, it must be taken
back within the value given in the table in figure 6.7.
proceeding as follows:
a) turn screw “A” clockwise as in figure 6.14 to decrease
the level of CO2;
b) turn screw “A” anti-clockwise as in figure 6.14 to increase
the level of CO2;
5.- once the check has been completed, seal the screw “A” in
figure 6.14 with red pain or something similar;
6.- press the RESET key again to enter the parameter
2010
and use the
and
keys, to modify
the value to
LOu
;
7.- press the RESET key to confirm the modification. Now
the burner will operate at minimum power for 10 minutes.
8.- wait for the CO2 measurement to stabilise;
9.- the value of CO2 at minimum power must correspond;
10.- once the check has been completed, seal the screw “B”
in figure 6.14 with red pain or something similar;
11.- press the RESET key again to enter the parameter
2010
and use the
and
keys, to modify
the value to
OFF
;
12.- press the RESET key to confirm the modification.
13.- hold the RESET key down for 5 seconds to exit the
“installer” menu.
14.- close the previously-opened domestic hot water tap.
