Analysis of combustion
Combustion is analysed in air (2) and flue gas (1) exemption areas as it is given on the picture. For
measuring it is necessary to:
1.Open exemption areas of air and flue gas
2.Put probes in
3.Press buttons
"+"
and
"-"
by heating sign for 5 seconds to activate the TEST mode
4.Wait 10 minutes until boiler gets into stable operation
5.Measure
Value of CO2 has to be in interval of 8,7 - 9% by natural gas (G20). By propane (G31) it is 9,5-10%.
In case, that analysis is done, while boiler is not in stable operation, errors in measuring may occur.
Combustion analysis
Setting of CO2 value by combustion
Setting and check of the CO2 on gas valve can be only by qualified service technician!
Description of gas valve:
A - Inlet pressure
B - Outlet pressure
C - Regulation screw - min. output setting
D - Regulation screw - max. output setting
By max.output is CO2 set by regulation screw D, by max.output is CO2 set by regulation screw C
Co2 test by max. output:
1- Put device for combustion analysis into flue gas outlet pipe.
2- Start boiler and test mode by pressing
"+"
and
"-"
buttons by heating
sign for 5 seconds.
3- Use
"+"
button to set heating to max output (100%)
4- Check, eventually set CO2 values by screw (1) for the range of
8,7 - 9,2 % for natural gas (G20) and 10 - 10,5 % for propane (G31)
5- Exit test mode after correct setting.
CO2 test by min output:
1- Put device for combustion analysis into flue gas outlet pipe.
2- Start boiler and test mode by pressing
"+"
and
"-"
buttons by heating
sign for 5 seconds.
3- Use
"-"
button to set heating to min. output (0%)
4- Check, eventually set CO2 values by screw (1) for the range of
8,7 - 9,2 % for natural gas (G20) and 10 - 10,5 % for propane (G31)
5- Set back to 100% and exit test mode after correct setting.
