18.3 CHECKING THE BURNER
The burner needs no cleaning.
• Check the burner surface for damage, replace the burner if necessary.
• Check the positioning of the flame detection probe.
• Verify that the distance of the ignition electrode is within tolerance as shown in the figure.
• Check that the burner surface insulation in the burner flange it is not damaged otherwise replace it.
Connect the gas supply with a new gasket, open the gas supply and check the boiler for gas leaks using a leak testing spray.

18.4 COMBUSTION PARAMETERS
To measure combustion efficiency and the toxicity of the products of combustion, the boiler
is fitted with two dedicated test points. One connection point is connected to the flue gas
discharge circuit ( A), and allows monitoring of the quality of the combustion products and
the combustion efficiency. The other is connected to the combustion air intake circuit ( B),
allowing checking of any recycling of the combustion products in case of coaxial pipelines.
The following parameters can be measured at the connection point on the flue gas circuit:
• temperature of the combustion products;
• oxygen O2 or carbon dioxide CO2 concentration
• carbon monoxide CO concentration.
The temperature of the comburent air must be measured on the test point located on the air
intake flue (B) by inserting the measurement sensor by about 9 cm (C).
To enable the " CHIMNEY SWEEPER" consult section 12.3.
