Ideal Isar HE 24 30 35 Boiler Ignition Lead 173510

Product Overview

The Ideal Isar HE Boiler Ignition Lead (Part Number: 173510) is a high-voltage electrical ignition component designed for selected Ideal heating systems.

The ignition lead forms part of the boiler's electronic ignition system, providing an electrical connection between the spark generator and ignition electrode.

It carries the high-voltage pulses required to produce a spark at the ignition electrode, allowing the gas-air mixture to ignite during the boiler's normal start-up sequence.

Correct ignition lead operation is important for reliable burner ignition and safe boiler operation.

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 ignition leads should be professionally inspected and electrically tested to confirm insulation integrity, electrical continuity and connection condition before installation.

Technical Insight & Common Failure Symptoms

The ignition lead is a high-voltage electrical cable that connects the boiler's spark generator to its ignition electrode.

During the ignition sequence, electrical pulses travel through the lead to the ignition electrode, creating the spark required to ignite the burner.

Over time, the lead may be affected by heat exposure, insulation deterioration, damaged connectors or electrical faults.

Possible symptoms that may indicate an ignition lead or associated ignition system problem include:

• Boiler failing to ignite or fire correctly.

• Intermittent ignition operation.

• Weak or absent ignition spark.

• Boiler failing to complete its normal ignition sequence.

• Ignition-related safety lockouts.

• Visible cracking or deterioration of the cable insulation.

• Loose, damaged or corroded electrical connections.

• Electrical arcing caused by damaged insulation.

These symptoms do not necessarily confirm a faulty ignition lead, as similar problems may result from ignition electrodes, spark generators, wiring, gas supply issues or other boiler components. Correct professional diagnosis should be carried out before replacement.

Compatibility

This part (MPN: 173510) is associated with selected Ideal Isar HE 24, 30 and 35 boiler systems.

Please verify the exact boiler model, GC number, ignition lead reference and connection arrangement against the manufacturer's technical documentation before ordering to ensure correct fitment.

Safety Advice

Boiler ignition leads are high-voltage components within the appliance's gas ignition system. Inspection, removal and installation must only be carried out by a Gas Safe registered engineer who is suitably qualified for the appliance and work being undertaken.

Always isolate the appliance's electrical supply before carrying out any work and follow the manufacturer's installation and servicing instructions. Ensure the ignition lead is correctly connected, securely routed and adequately insulated. All required ignition, burner operation, combustion and safety checks must be completed before the boiler is returned to service.
