3. BURNER’S OPERATING PRINCIPLES
First start
The pellet burner has predetermined configurations of maximum and minimum power rating by
the manufacturer.
The authorized trained technician who will fire up the burner has the option – if necessary – to
reduce the maximum power of the burner to fit the power of the boiler or a specific user’s
requirement.
Operation of the burner
First check
Once the start command is given by the user, the burner performs a series of checks to the
whole system in order to ensure that all parameters permit its smooth and safe start.
To this effect the burner checks immediately a number of parameters e.g. the water
temperature or the exhaust gas temperature. The values of all parameters should be within a
predetermined and acceptable range as indicated by the manufacturer to enable start of the
burner.
Combustion of the burner
After the controller performs the first check, the auger feeds the pellet burner with a specific
quantity of pellet and ignition is generated with the use of an electrical heating element.
Burning
When the flame sensor “detects” - within a specific time frame - that the flame’s intensity is
sufficient then the pellet burner will proceed to the BURNING PHASE aiming to the maximum
power level.
Should the flame sensor does not confirm the required intense of flame within the specific time
frame then the starting process is stopped and an “error” notification is displayed which is
accompanied with the code diagnosing the type of error (see §18 “Troubleshooting”).
