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.

them with a suitable tool as shown in the figure
13.
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 (8, 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.
