3.6Combustion Analysis

-the potentiometer for regulating the soft-light feature, the setting for which can range from the minimum thermal power to the maximum:

G20	5 mbar
G25	18 mbar
G30-31	19 mbar

-the potentiometer for the maximum thermal power for the heating system, maximum thermal power setting (factory set at the maximum value, unless indicated otherwise on the adhesive sticker located in proximity to the potentiometer);

-The connection to the diagnosis device (TCS-TCS2).

The boiler is designed to make it easy to analyse the combustion by-products.

Using the especially designed apertures, readings can be taken on the temperature of the combustion by-products and of the combustion air, as well as of the concentrations of O2 and CO2, etc.

The best maximum-power test conditions for the heating system are when the selector “C” is turned to the flue analysis setting.

3.7Fume Discharge Monitoring

The discharge/ventilation of the exhaust fumes can be monitored to check for losses in general pressure in the system. This is done to eliminate the cause of lighting failure with the main burner not indicated by a shutdown status.

With a differential manometer connected to the test socket on the combustion chamber, the DP value for the air pressure switch can be taken. The measured value should not be less than 10 mbar under maximum thermal power conditions (with the knob “C” on the flue test setting) in order for the unit to function properly and without interruption.
