What it is
The Riello 503 SE is a burner control box manufactured by Riello for use on Riello oil burners. It manages the burner's start-up sequence and safety lockout, and is listed within the Riello burner spares range. It is a service part for the burner rather than the boiler itself.
Signs this part needs replacing
- The burner locks out shortly after start-up and needs a manual reset each time
- The burner does not run at all when there is a call for heat
- Repeated or intermittent lockouts with no obvious fuel or ignition fault
- The burner fails to complete its start-up sequence
- Erratic burner operation that cannot be traced to the nozzle, photocell or solenoid
Before you order
- Read the burner data plate and confirm the burner type code against the fit list above
- Check the marking on the existing control box to confirm it is a 503 SE
- Confirm the burner series (Press 1G, 2G, 3G, 4G or GBV) before ordering
- Have the burner model and code to hand when checking compatibility
