MAINTENANCE

Disconnect the electric supply to the burner by switching off the main power switch and close the
gas shut-off valve before maintaining or checking the system.
The burner requires scheduled maintenance that must be carried out by qualified personnel and in compli-
ance with local legislation.
Scheduled maintenance is vital for the smooth operation of the burner; it avoids waste of fuel and reduces
harmful emissions into the atmosphere.
THE FUNDAMENTAL OPERATIONS TO CARRY OUT ARE AS
FOLLOWS:
Check at regular intervals that the holes of the gas head are

not obstructed. If they are, clean them with a suitable tool as
shown in the figure 11.
Check there are no occlusions or obstructions in the inlet or

return pipes, in the air suction areas and in the combustion
product waste pipe.
Check that the burner and gas train electrical connections are

correct.
Check that the positioning of the air pressure test point (6, fig.

1, page 2) is correct.
Check that the gas train is suited to the burner capacity, the type

of gas used and the network gas pressure.
Check that the positioning of the combustion head is correct and that it is properly fixed to the boiler.

Check that the air damper is positioned correctly.

Check that the ionisation probe and the electrode are positioned correctly (see fig. 10, page 10).
