CONTROL TESTS
BEFORE THE FIRST IGNITION
Before the first ignition, we recommend you check the following:
- The system has been filled to the right pressure and has been purged.
- There is no leakage of water or fuel.
- The electrical supply is correct.
- The entire flue system has been carried out properly and that it is not near inflammable parts.
- There are no inflammable substances near the appliance.
- The burner is proportioned to the boiler capacity.
- The water interception valves are opened.
- Check the position and calibration of the thermostats.
- Check the delivery of the hot water.
AFTER THE FIRST IGNITION
After the first ignition, we recommend you make sure that:
- The burner works correctly. This control must be carried out using the correct instruments.
- The thermostats work correctly.
- The water circulates inside the system.
- All the smoke is completely evacuated through the flue.
NOTE: With a new boiler or after a long period of inactivity, one can check for the locking of the circulating
pump. In this case it is necessary to unscrew the front stopper and make the motor shaft rotate with a
screwdriver.
SWITCHING ON - SWITCHING OFF
FIRST IGNITION
Once the preliminary controls have been carried out, make the ignition manoeuvres as follows:
- Open the fuel interception valve (if present).
- Set the boiler thermostat to the desired value.
- Shut off the switch upstream the boiler and the Summer/Winter switch placed on the control panel.
SWITCHING OFF
When switching off for short periods of time, act on the on/off switch placed on the control panel.
When switching off for long periods of time during winter, so as to avoid damage caused by freezing
temperatures, it is necessary to introduce a suitable anti-freeze into the system or completely drain the system.
