9 If your Boiler Fails to Light
If you experience a problem with your boiler, it may be due to something quite simple and by making a few checks you can quickly
rectify it for yourself. If your boiler fails to light, please follow the procedure given below, starting with STEP 1:
STEP 1
Is the burner control panel display blank?
NO - go to STEP 2
YES – Check the following:
• Is the electrical supply to boiler and heating system controls switched on at fused spur?
• Has the fuse in the fused spur blown?
• Are all the plugs at the rear of the hopper, the rear of the boiler and the side of the burner fitted
correctly?
• Is the combustion chamber door closed and the catch fully engaged?
• Has the boiler overheat thermostat tripped? Remove cap to check. If yes, press the reset button.
Refer to Section 4. If this does not rectify the problem, contact your Installer.
• Has the pellet feed tube thermostat tripped? Reset the thermostat. Refer to Section 6 – Pellet Feed
Tube Thermostat for details. If this does not rectify the problem, contact your Installer.
If, after checking the above, there is still a problem then contact your Installer for assistance.
STEP 2
Is one of the four ERROR MESSAGES scrolling across the bottom of the burner control panel display?
YES – go to STEP 4
NO – go to STEP 3
STEP 3
Is there a cursor next to the ‘Heating Demand’ symbol on the burner display?
YES – Check the temperatures on the burner display.
• Is the H2O value on the display higher than the set point temperature value plus 5°C. If so, there is
NO fault but the boiler is waiting for the system temperature to drop before firing again.
NO – Check the following:
• Is the burner STANDBY/ON switch set to the ON position? If not, then set it to ON.
• Is there a sufficient quantity of pellets in the pellet hopper? If not, top up the hopper with pellets.
• Are the heating system controls (programmer, room thermostat, etc.) ‘calling’ for heat? If not, set
controls to call for heat.
If, after checking the above, there is still a problem then contact your Installer for assistance.
STEP 4
Which one of the four ERROR MESSAGES is scrolling across the bottom of the burner control panel
display?
• FAILED PELLET LIGHTING – go to STEP 5
• SERVO MOTOR BLOCKED – go to STEP 6
• PROBE FAULT – go to STEP 7
• AIR PRESSURE ERROR – go to STEP 8
