To optimise boiler efficiency, carry out the following annual controls:
• Check the appearance and airtightness of the gaskets of the gas and combustion circuits. Replace any worn seals with new
original spares;
•
Check the state and correct position of the ignition and flame-sensing electrodes;
•
Check the state of the burner and make sure it is firmly fixed;
• Check for any impurities inside the combustion chamber. Use a vacuum cleaner to do this;
• Check the pressure of the heating system;
• Check the pressure of the expansion vessel;
• Check the fan works correctly;
•
Make sure the flue and air ducts are unobstructed;
• Check for any impurities inside the siphon (for condensation boilers);
•
Check the magnesium anode, where present, for boilers fitted with storage boilers.
It is advisable not to use the service cap at the base to empty and clean the siphon. Remove the siphon from inside the boiler
and clean it with a jet of water. Fill the siphon with clean water and put back in place, making sure that it is properly connected.
18.1 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 ( ) or carbon dioxide (
) concentration;
• carbon monoxide (
) 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 8 cm (
C
).

18.3 REPLACEMENT OF PARTS
If one or more of the following components are replaced:
• Water-fumes exchanger
• Fan
• Gas valve
• Gas nozzle
• Burner

19. DISMANTLING, DISPOSAL AND RECYCLING
Only qualified technicians are authorised to service the device and system.
Before dismantling the appliance, be sure to disconnect the power supply, close the gas inlet shutoff valve and secure all of the
boiler and system connections.
Dispose of the appliance correctly according to the laws and regulations in place. The appliance and accessories cannot be
discarded along with normal household waste.
More than 90% of the materials that make up the appliance are recyclable.
