STARTING - SHUT-OFF
FIRST STARTING
After making preliminary checks, perform the following starting procedures:
1 open the fuel on-off valve (if present);
2 set the regulation thermostat (Fig. 2) to the value required;
3 turn on the switch upstream of the boiler and the main switch (Fig. 2) located on the control
panel.
SHUT-OFF
If the boiler will not be utilised for short periods of time, turn off the main switch (Fig. 2) on the control
panel.
If the boiler will not be utilised for long periods during the winter, it is necessary to add antifreeze to the system
or to empty the system completely to prevent damage from freezing.
REGULAR MAINTENANCE
Boiler maintenance must be carried out by qualified personnel.
The unit should be checked once a year before the start of the winter season. This check must include, in
addition to the cleaning status of the boiler, that all control and safety devices, as well as the burner, are in
good working order.
All flue gas discharges must also be checked.
