23. annual maIntenanCe

To optimise boiler efficiency, carry out the following annual controls:
• check the appearance and airtightness of the gaskets of the gas and combustion circuits;
• 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 gas valve is correctly calibrated;
• 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 fitted on certain boilers;
• check the magnesium anode, where present, for boilers fitted with storage boilers.
WarnInGs
Before commencing any maintenance operations, make sure the boiler is disconnected from the power supply.
afterwards, move the knobs and/or operating parameters of the boiler to their original positions.
This is a high static head pump fit for installation on any type of single or double-pipe heating systems. The air vent valve
incorporated in the pump allows quick venting of the heating system.
To purge the exchanger and/or the DHW system we suggest the use of Cillit FFW-AL or Beckinser HF-AL.
For specific areas where water hardness exceeds 20°F (1°F = 10 mg of calcium carbonate per one litre of water) we
recommend you install a polyphosphate metering device - complying with the applicable regulations - in the cold water
inlet
pipework.
