THERMOSTAHL PELLET STAR, Instruction Manual

For increasing the efficiency, a delay of the exhaust gases was made by using special
turbulators who will increase the thermal transfer.
3.5 Boiler/ burner cleaning interval.
Depends on the content of inorganic ash from the pellets which is specified in the (DIN Plus)
quality certificate of those.
Normally this should be between 0,03 -1 % but not to surpass 1 % so at 100 Kg pellets it
should result 1 Kg of ash.
So at a consumption of 30 Kg/day it is recommended to clean the boiler after 10 days of
continuous function of the boiler when the amount of ash in the boiler is over the burner level
preventing blocking it with ash which is over 3 Kg, if the ash content is greater the cleaning
should be done more often.
Request quality certification and test bulletins from the pellet producers and use only pellets
certified with DIN + and an ash content under 1% and humidity between 6-10%.
The calorific power is another very important factor on which the performances of the burner
and the boiler depend.
The burner may work for 7-10 days with no need for cleaning if used pellets certified with
DIN+.
For a function without problems (low consumptions and optimal thermal transfer), we
recommend cleaning the burner every 2-3 days and the system after the following timetable:
NOTE: No welding works may be done to the installation until the electric power is
disconnected and the electronic plate (the burner) removed.
According the pellets type, it is compulsory to clean the boiler every week or every 2 weeks.
First stop the power by pressing the on /off button (This should be done after the fire is off).
The boiler door should be open together with the ashbin from below and the ash from the
base of the boiler is removed with the poker like in the picture above the ash should fall
directly into the ash bin.
