Riello Air Damper Assembly 3020239

The air damper assembly is a Riello burner component that regulates the volume of combustion air drawn into the burner head. It is listed for the Riello R40 GS 3 and R40 GS 5 burner ranges and forms part of the burner's air control arrangement. Correct damper operation is essential for stable ignition and clean combustion.

• The burner fails to light or locks out repeatedly despite a clean nozzle and adequate oil supply.
• Combustion readings drift and cannot be set correctly, with CO or CO2 outside the expected range.
• The flame is smoky, sooty or unstable at start-up.
• The damper blade or its linkage is seized, bent or does not move freely through its travel.
• Visible damage, corrosion or excessive play at the damper spindle or mounting points.

• Read the burner data plate and confirm the model, code and type match the fitment list above.
• Check the existing damper assembly for the part number marking before removing it.
• Inspect the damper linkage and spindle for wear, as related components may also need attention.
• Confirm the burner is due for service and that combustion settings will be re-checked after fitting.
