Ideal Concord CXS/SD 40/H 120/H Boiler Flame Detection Electrode 112364

Product Overview

The Ideal Concord Flame Detection Electrode (Part Number: 112364) is a flame-sensing component designed for selected Ideal Commercial boiler systems.

Part number 112364 is identified in Ideal's technical documentation as a Flame Detection Electrode BE/3459/SI, forming part of the boiler's burner flame supervision system.

The electrode detects the presence of a flame during burner operation and provides an electrical signal to the boiler's flame supervision controls.

Reliable flame detection is essential for confirming burner operation and allowing the boiler's safety controls to respond appropriately if the flame is lost.

ℹ️ Product Condition Options:

This part may be available in New or Refurbished condition. Please select your desired option from the dropdown menu above. Refurbished electrodes should be professionally inspected and tested to confirm their condition and correct operation before installation.

Technical Insight & Common Failure Symptoms

The flame detection electrode operates through flame ionisation. When a burner flame is established, a small electrical current passes through the flame and is detected by the boiler's flame supervision circuit.

The control system uses this signal to confirm flame presence. If the required flame signal is not detected, the boiler's safety controls may interrupt burner operation.

Over time, electrode performance may be affected by contamination, damaged insulation, deterioration of the electrode surface or poor electrical connections.

Possible symptoms that may indicate a flame detection electrode or associated combustion system problem include:

• Burner igniting but shutting down shortly afterwards.

• Burner flame not being recognised by the control system.

• Intermittent flame detection.

• Boiler entering a flame failure or ignition-related lockout.

• Burner failing to maintain operation despite successful ignition.

• Visible contamination or deterioration of the electrode.

• Cracked ceramic insulation or damaged electrical connections.

These symptoms do not necessarily confirm a faulty flame detection electrode, as similar problems may result from burner condition, gas supply issues, electrical connections, earthing faults or other combustion components. Correct professional diagnosis should be carried out before replacement.

Compatibility

This part (MPN: 112364, Electrode Reference: BE/3459/SI) is associated with selected Ideal Concord CXS/SD 40/H–120/H commercial boiler systems.

Please verify the exact boiler model, serial number, part number, electrode dimensions and connection arrangement against the manufacturer's technical documentation before ordering to ensure correct fitment.

Safety Advice

Boiler flame detection electrodes are safety-critical components within the appliance's combustion and flame supervision system. Inspection, removal and installation must only be carried out by a Gas Safe registered engineer who is suitably qualified for the commercial boiler and work being undertaken.

Always isolate the appliance's electrical and gas supplies as required before carrying out any work and follow the manufacturer's servicing instructions. Ensure the electrode is correctly positioned and connected, and that any disturbed combustion chamber components or seals are correctly refitted. All required flame detection, burner operation, combustion and safety checks must be completed before the boiler is returned to service.
