3. SERVICE AND MAINTENANCE

All the adjustment, commissioning and maintenance operations must be performed by Quali ed Personnel, in compliance with the standards
in force.
FERROLI S.p.A. declines all liability for damage to persons and/or things deriving from the tampering with the appliance by unquali ed or
unauthorised persons.
Before performing any cleaning or maintenance operations, disconnect the appliance from the mains power supply using the system switch
and/or the special on-off devices.
3.1 Commissioning
Checks to be performed on rst ignition, and after all maintenance operations that involve the disconnection of the appliance from the systems
or intervention on the safety devices or parts of the boiler:
Before rst ignition
Before igniting the boiler for the rst time, check that:
a the system is lled at the right pressure and any air has been correctly vented;
b there are no water or fuel leaks;
c the electrical power supply is correct;
d all the ues have been installed correctly and not too near to or across any ammable parts;
e there are no ammable substances near the appliance;
f
the burner is suitably sized for the output of boiler;
g the water on-off valves are open.
First ignition
After having carried out the preliminary checks, the following ignition operations can be performed:
1 Open the fuel on-off valve.
2 Set the thermostat 4 (Fig. 1) to the desired value.
3 Close the switch upstream from the boiler and switch 5 (Fig. 1) on the control panel.
At this stage, the burner will be ignited and the boiler will start operation.
After rst ignition
After rst ignition, check that:
1 The door of the burner and smokebox are well sealed.
2 The burner is working correctly. This check should be performed using the required instruments, following the manufacturer's instruc-
tions.
3 The thermostats are working correctly.
4 Water is circulating in the system.
5 The ue gas is completely expelled through the ue.
3.2 Adjustments
Adjusting the burner
The ef ciency and correct operation of the boiler depend above all on accuracy of the adjustments made to the burner.
Carefully follow the instructions provided by the manufacturer. Two-stage burners must have the rst stage adjusted to an output that is no
lower than the minimum rated output of the boiler. The output of the second stage must not be greater than the maximum rated output of
the boiler.
3.3 Shut-down
For brief periods of inactivity, simply use switch 5 (Fig. 1) on the control panel.
For extended periods of inactivity, as well as operating switch 5, the fuel on-off valve must also be closed.
3.4 Maintenance
To ensure the maximum reliability of the heating system and minimum running costs, the boiler must be cleaned regularly, at least once a year.
These maintenance operations must be performed by quali ed and specialist personnel.
Cleaning the boiler
1 Disconnect the power supply to the boiler
2 Remove the upper and lower front panel.
3 Open the door by unscrewing the knobs.
4 Clean the inside of the boiler and the entire ue gas discharge path, using a brush or compressed air.
5 Close the door again, and fasten it using the knob.
To clean the burner, refer to the instructions provided by the manufacturer.
