• The gas and water systems must be airtight.
• The water pressure in the cold water system must be approx. 1 bar; otherwise, bring
it to that value.
• The circulating pump must not be blocked.
• The expansion tank must be filled.
• Check the magnesium anode and replace it if necessary.
The boiler casing, control panel and aesthetic parts can be cleaned with a soft

detergents and solvents.
Accessing the electrode and nozzle
• Disconnect the transformer electrode cables and remove the photoresistance 1, and
the union 2 connecting the oil pipe to line 3 of the nozzle. Loosen the screws 4 and
pull out the nozzle-baffle-electrode flange assembly.
• Undo the screw 5 to remove the baffle and screw 6 to remove the electrodes. Proper
cleaning of the nozzle is obtained by removing the filter and cleaning the slots and
spraying hole with petrol, rinsing it with fuel oil. When reassembling everything, pay
attention to the correct positioning of the electrodes-baffle.
