Riello Cam Assembly 3012263

The Riello cam assembly, part number 3012263, is a burner component used across the Riello Enne/emme and Gi/emme ranges. It forms part of the burner's mechanical control linkage, where the cam profile sets the position of the air damper and fuel metering through the operating cycle. Correct cam geometry is what keeps the air and fuel relationship consistent as the burner moves between stages.

• Burner combustion readings drift and cannot be held steady across the firing range
• Air damper position no longer tracks the cam profile through the modulation stroke
• Visible wear, scoring or deformation on the cam face or its follower
• Linkage binds or the cam fails to return cleanly to its start position
• Repeated lockouts after servicing that cannot be resolved by adjustment alone

• Confirm the burner model and code against the fitment list above
• Check the existing cam for wear or damage before stripping the linkage
• Verify the part number 3012263 matches the number on the component being replaced
• Have the burner's commissioning data to hand so settings can be rechecked after fitting
