Burner model identification
Burners are identified by burner type and model. Burner model identification is described as follows.
Technical specifications
Note: the Output values are referred to comburent air temperature lower than 50°C.
NOTE ON THE BURNER WORKING SERVICE: for safety reasons, one controlled shutdown must be performed every 24 hours of
continuous operation.
