The boiler will run the ignition phase, and will remain on until the set temperatures have been reached. If problems occur during ignition or ope-
ration, the boiler will "LOCKOUT," as signaled by the red light on the burner and the red indicator on the control panel. After a "LOCKOUT," wait
about 30 seconds before resetting the ignition conditions. To reset the ignition conditions, press the burner "button/light" and wait for the flame
to ignite. If this operation fails, it can be repeated a maximum of 2 or 3 times. Then check:
- The instructions manual for the burner.
- The section "CHECKING BOILER OPERATION."
- The electrical connections shown on the diagram next to the control panel.
Once the boiler has started, check that it stops and starts again:
- Adjust the setting on the boiler thermostat.
- Operate the main switch on the control panel.
- Set the room thermostat, timer, or temperature controller.
- Check that the pumps are not blocked and rotate correctly.
- Check that the boiler shuts down completely by operating the main system switch.
If all conditions are correct, restart the appliance, check the combustion (flue gas analysis), fuel rate, and tightness of the gaskets on the door
and smokebox.

7.6 Checking burner operation

- Check the instructions manual for the burner.
- Follow all local regulations and standards with regard to burner maintenance.

7.7 Troubleshooting

The following is a list of the main faults and problems that may occur during boiler operation, specifying possible causes and solutions.
FAULT
THE BOILER IS EASILY SOILED
CAUSE:
Burner poorly adjusted
Flue blocked
Burner air intake path dirty
THE BOILER DOES NOT REACH THE SET TEMPERATURE
CAUSE:
Boiler body dirty
Boiler/burner combination
Burner flow-rate insufficient
Control thermostat
BOILER THERMAL SAFETY SHUTDOWN WITH INDICATOR LIGHT ON THE CONTROL PANEL
CAUSE:
Control thermostat
Lack of water
Air present
THE BOILER REACHES THE SET TEMPERATURE, BUT THE CENTRAL HEATING SYSTEM IS COLD
CAUSE:
Air present in the system
Pump fault
Minimum thermostat (if featured)
ODOR OF UNBURNED SUBSTANCES
CAUSE:
Flue gas leaking into the environment
FREQUENT ACTIVATION OF THE SAFETY VALVE
CAUSE:
System circuit pressure
System expansion vessel
SOLUTION:
Check the burner adjustment (flue gas analysis)
Clean the flue gas path and the flue
Clean the burner air intake
SOLUTION:
Clean the flue gas path
Check the data and adjustments
Check the burner adjustment
Check correct operation
Check the set temperature
SOLUTION:
Check correct operation
Check the set temperature
Check the electrical wiring
Check the probe bulbs
Check the circuit pressure
Check the vent valve
SOLUTION:
Vent the system
Reset the pump
Check the set temperature
SOLUTION:
Check that the boiler body is clean
Check that the flue is clean
Check the tightness of the boiler and flue
SOLUTION:
Check the fill pressure
Check the system circuit
Check the calibration
Check the set temperature
