Burner model identification
Burners are identified by burner type and model. Burner model identification is described as follows.
Technical Specifications
Heavy oil net calorific value (Hi): 40.43 MJ/kg (average value).
*NOTE ON THE BURNER WORKING SERVICE: for safety reasons, one controlled shutdown must be performed after 24 hours
of intermittent operation.
WARNING: the burners are supplied for 400V three phase supply; in case of three phase 230V supply, replace the thermal overload
relays. Maximum output is referred to a null backpressure in the furnace.
