TECHNICAL CHARACTERISTICS
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.
When correctly installed, the unit works in any outside climatic conditions; in any case, in critical conditions (strong wind, frost, etc. )
the safety systems can cut in and shut down the boiler.
The boiler comes complete with a fume extractor, pellet feed gearmotor, , high efficiency pump for the heating circuit and of all the
control and safety components. During operation the unit generates very little noise, with levels between 38 and 42 dB.
The data shown here is provided as a guideline and is not binding, and may change based on what type and quality of pellet is used.
Ravelli reserves the right to make any changes in order to improve product performance.
