Combustion Analysis
To perform the analysis of combustion must be installed
accessories with flue/air test point (see Fig. Below).
Using the test point to detect the temperature of the flue gases
and combustion air, concentrations of O2 and CO2, etc.
It is possible activate the flue test mode by pressing and holding
the RESET button for 10 seconds on the display appear
(see parameter 270)
The boiler will return to normal operation after 30 minutes. The
boiler can be returned to normal operation sooner by switching
the boiler off and on again. Close properly test points after the
analysis of combustion.
Product of Combustion - Discharge Monitoring
In the boiler, it is possible to monitor the correct operation of the
flue exhaust/air intake, checking for a loss of general pressure
in the system. Through the use of a differential manometer
connected to the test points on the intake/exhaust pipes (see
Fig. Below), it is possible to detect the ∆P of operation of the air
pressure switch.
The value detected should not be less than 0.47 mbar (24 kW)
under conditions of maximum thermal power in order for the
boiler to function properly and without interruption.
TO PERFORM THE ANALYSIS OF
COMBUSTION MUST BE INSTALLED
