- the potentiometer for regulating the soft-light feature, the setting for which
can range from the minimum thermal power to the maximum:
- 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 O
The best maximum-power test conditions for the heating system are when the
selector "C" is turned to the flue analysis setting.
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.
G20 5 mbar
G25 18 mbar
G30-31 19 mbar
