FAULT

CAUSE

CORRECTIVE ACTION

Control thermostat problem

The boiler keeps shutting

down, and the control panel

warning light comes on

Check the functioning of the

thermostat

Check the temperature setting

Check the electrical wiring

Check the sensors

No water supply

Air in the circuit

Check the circuit pressure

Check the vent valve

Boiler dirty

Clean the flue gas pipes

Boiler and burner mismatched

Check specifications

and settings

Insufficient air/fuel flow to burner

Check and adjust the burner

Control thermostat problem

Check the functioning of the

thermostat

Check the temperature setting.

The boiler does not reach

its temperature setpoint

The boiler becomes dirty very

quickly

Burner badly adjusted

Blockage in stack
