hopper can cause malfunctions and/or the pellet feeding system to stop.

4.5 TECHNICAL DESCRIPTION

The boiler works exclusively on pellets and enables easy installation with the heating and
DHW system. Its automatic control systems ensure optimum thermal efficiency and complete
combustion; there are also systems to ensure safe operation for the internal components and
the user. This unit must only be used for heating water to a temperature lower than boiling
point.
A properly installed unit works with any outdoor climate. Critical climatic conditions (strong
wind, frost, etc.) can trigger the safety systems that turn the boiler off.
The boiler comes complete with a fume extractor, pellet feed gearmotor and the control -
