DESCRIPTION OF CONTROL PANEL
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:

NOZZLE CLEANING AND REPLACEMENT
Use only the suitable box wrench provided for this operation to remove the nozzle, taking care to not
damage the electrodes. Fit the new nozzle with the same care.
Note: Always check the position of electrodes after having replaced the nozzle (see illustration). A wrong
position could cause ignition troubles.
