Technical data
Name plate and serial number
The name plate can be found on the rear panel of the boiler.
Important information:
Ensure you retain all supplied documentation. In the event of a claim under the warranty or for the
subsequent delivery of spare parts we will always require the serial number of the boiler. Without the
serial number and date of purchase, we cannot recognize any warranty.

from LOHBERGER HEIZTECHNIK GmbH consists of a
pellet combustion chamber made of refractory concrete, a tubular heat
exchanger with cleaning coils, electric ignition and automatic grate de-
ashing. The pellet feed into the pellet combustion chamber happens IBS *
tested input.
In the default setting the system is operated automatically by the
microprocessor system with associated sensors and switches.

Mode of operation:
The boiler runs as long as the system requires energy or stores energy, then the boiler switches to
standby mode. If the system (heating & dom. water) requires energy the pellet burner re-ignites
automatically.
The supply of fuel (pellets) is implemented optionally from the right (standard) or left via a feed
channel. Using a variable-speed flue gas fan, primary air is supplied to the fuel through the grate,
and secondary air at the outlet of the combustion chamber to the combustion gases. The combustion
gases flow through the pelet fuel chamber and are directed through the tubular heat exchanger to
the flue.
The 180 ° deflection in the tubular heat exchanger guarantees a high degree of separation of ash
into the rear ash tray.
At regular intervals an electrical drive empties the ash from the pellet combustion chamber into the
underlying front ash pan.
The supply of fuel (split logs) is via manual insertion into the fuel chamber. The air supply for split
log operation is ensured by primary and secondary air ports. The combustion gases also flow via the
tubular heat exchanger to the flue.
The entire combustion control happens via a lambda probe and a flame temperature sensor, the
power control via a boiler temperature sensor. Total air management is achieved via a primary and a
secondary air valve and variable speed induced draught. This ensures a stable negative pressure in
the combustion chamber and the conveying of the combustion gases to the chimney.
The tubular heat exchanger is cleaned by means of an integrated automatic cleaning mechanism.
