Does anyone know where i can download a schematic drawing of Inter B9B, B9C & B11 Oil Burners ?

I have tried looking on the Bentone website but no luck there, and when i search for the burner types, it just comes up with a link to info on Worcester Bosch oil boilers, but the info on their site just gives sizes and settings, but what i need is an explosive drawing of all the parts within the burner itself. If anyone knows where i can get these drawings from to help my project it will be appreciated.Does anyone know where i can download a schematic drawing of Inter B9B, B9C %26amp; B11 Oil Burners ?just try to google or ask.comDoes anyone know where i can download a schematic drawing of Inter B9B, B9C %26amp; B11 Oil Burners ?NODoes anyone know where i can download a schematic drawing of Inter B9B, B9C %26amp; B11 Oil Burners ?phone worcester bosch on 08705266241
