Technical description of burner
Burner operation is based on principle of pellets falling from pellet feeder through inlet hose and
inlet pipe on the grate to be burned.
Burner is equipped with electric ignition device, that automatically lights pellets fallen on the grate.
Ignition begins, when thermostat gives instruction to burner. Burner has own built-in thermostat (if
there is no boiler / external thermostat, eventually combined device with room thermostat). Its
temperature sensor must be in suitable casing in the boiler´s water coat. Switch-on and switch-off
temperature can be adjusted via the burner menu buttons. Actual operation data are visible on
display.
ATTENTION! Head of boiler temperature sensor must not be treated with any contact
liquid, nor paste.
Burner output is set from production for the range of 14–30 kW and it is divided into 3 levels:
1. (14 kW), 2. (22 kW) and 3. (30 kW).
Selected output level is written on display during the operation. Output level can be selected by
burner menu buttons and displayed information. Output range can be changed in advanced menu in
two levels: 8–12 kW and 14–30 kW.
Burner is equipped with automatic grate cleaning mechanism. When thermostat achieves required
temperature, the burn-down cycle is started, the grate goes out to be cleaned by scraping. Thereby,
the longer usage period is ensured, with no need to dismantle burner from boiler body. Burner uses
control system to regulate gear of ash removing auger and gear of exchanger cleaning by
turbulators.
Boiler convection parts should be cleaned periodically to keep high efficiency of heating.
Burner is intended for combustion of wood pellets with diameter of 6–10 mm.
Burner is manufactured following the industrial norms and prescriptions and it was tested and
approved in conformity with directives about low voltage devices and with directives about
electromagnetic disturbance.
