Riello End Cone 3013391

The end cone is a Riello combustion head component that sits at the discharge end of the burner blast tube, where it shapes the air and fuel mixture as it leaves the head. It is listed for RLS, RS and BLU series burners and is identified by Riello part number 3013391. Renewing the cone restores the correct combustion head profile when the existing cone has been distorted, eroded or carboned up.

• Visible cracking, distortion or erosion at the cone tip or body.
• Heavy soot or carbon build-up on the cone that does not clean back to bare metal.
• A flame that has become unstable, misshapen or visibly different from the commissioning record.
• Combustion readings that drift out of the set range, particularly rising CO.
• Discolouration or heat damage on the blast tube end around the cone.

• Check the burner model and type code against the Fits list above.
• Inspect the existing cone for the correct profile before ordering.
• Allow the burner to cool fully and isolate the electrical and fuel supplies before dismantling the combustion head.
• Check whether the combustion head joint uses a gasket or seal that should be renewed at the same time.
