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
