YEARLY CH ECKS
The burner’s periodical check (firing head, electrodes etc.) must be carried out by authorised personnel one or two
times per year, depending on the utilisation. Before going on with the maintenance controls of the burner, it should be
advisable to check its general conditions, according to the following steps:
Unplug the burner; close the fuel cock; shut down the gas supply; remove burners cover and clean the fan and air
intake; clean the firing head and check the electrodes position; reassemble all the parts; check the connections sealing;
check the chimney; start the burner and check the combustion flue (CO2 = 9.5 ÷ 9.8; O = lower than 75 ppm).
BEFO RE EVERY INTERVENTION CHECK:
The electric system is duly powered and the burner is plugged in.
The gas pressure must be the suitable one and the gas cock open.
The control devices must be properly connected.
When all the above conditions are met, start the burner by pressing the lockout enable pushbutton.
Check the burner’s cycle.
TH E BURN ER DOES NOT ST A R T :
Check the ON/OFF switch, the thermostats, the motor and the gas pressure.
The master switch is in position “0”. Fuses are blown out.
The control box is faulty.

Check the air pressure switch.
Control box faulty. Ignition transformer faulty.
Check the ignition cable. Electrodes are dirty or in wrong position.
Nozzles are clogged or worn. Filters are clogged. Light-oil pressure is too low.
Combustion air’s flow rate too high related to nozzle output.

The photoresistor does not detect the flame.
The filters are clogged. Light-oil pressure too low.
Combustion air’s flow rate too high related to nozzle output.

Check gas governor and gas filter.
Check gas pressure through a manometer.
Check ionization value (min. 200 µA).
