3.3 Self Cleaning Burner Features
The self cleaning burner system allows the burner to maintain optimum combustion
by maintaining the combustion tube in a clean condition. The cleaning process is
activated after each time the system goes into an extinguishing phase (or after a
number of run cycles as required). The controller can also be programmed that after
a pre-determined number of hours running the system can shut down, clean and
then restart . This will prevent any “clinker “ build up in the combustion tube.
Cleaning of the burner tube is carried out by compressed air. A mini air compressor
charges a storage tank of air and when this has reached the correct pressure a
solenoid valve releases a short high pressure jet of air into the burner which clears
any clinker or debris into the de-ash augers.
If the temperature in the pellet feed pipe reaches a high temperature a safety
thermostat will signal the controller to shut down and signal an error “Er 03” on the
LCD display to warn of a high temperature occurrence.
The combustion fan of the burner regulates the combustion quality and is controlled
automatically. The ignition element creates the initial combustion during start up
and will turn off when a full flame is detected in running mode.
