MAINTENANCE
YEARLY CHECKS
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 burner's cover and clean the fan and air
intake; clean the firing head and check the electrode's position; reassemble all the parts; check the connection's sealing;
check the chimney; start the burner and check the combustion flue (CO2 = 9.5 ÷ 9.8; O = lower than 75 ppm).
BEFORE 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.
THE BURNER DOES NOT START:
Check the ON/OFF switch, the thermostats, the motor and the gas pressure.
The master switch is in position "0". Fuses are blown out.
