Saunier Duval Burner S5617200

The S5617200 is a burner supplied by Saunier Duval for use in its Ecosy and Enviroplus gas boiler ranges. The burner carries the gas/air mixture and delivers the flame into the combustion chamber, so its condition directly affects ignition, flame stability and combustion quality. It is listed as a replacement for the earlier code 561720000.

• The boiler fails to ignite or repeatedly locks out on ignition attempts
• An unstable, lifting or partially extinguished flame is visible at the burner
• The burner surface is distorted, corroded or blocked across the flame ports
• Soot deposits or discolouration build up on the burner body or nearby components
• Combustion readings fall outside the expected range and cannot be corrected by servicing

• Confirm the appliance model and, where applicable, the build date against the fitment list above
• Check the existing burner part number or the replaced code 561720000 before ordering
• Inspect the burner, ignition and gas valve components together, as faults often overlap
• Work on gas-carrying components must be carried out by a competent, registered engineer
