Ideal Ignition Lead Imax Xtra 174424

The Ideal 174424 is an ignition lead (HT lead) supplied for Ideal Commercial Imax Xtra appliances. It carries the high-tension spark from the ignition transformer or control board to the ignition electrode, so the burner can be lit reliably on each demand for heat.

As a high-voltage cable, the lead is exposed to heat, vibration and repeated sparking cycles, and its insulation and end connectors are the parts most likely to degrade over time. This lead is listed under the spare part type Cables, Leads & Wiring Harnesses.

• The appliance attempts to fire but there is no spark at the ignition electrode
• Repeated lockouts or failed ignition on a call for heat
• Visible cracking, splitting or perishing of the lead insulation
• Scorching, blackening or a burnt smell around the lead or its connectors
• Intermittent ignition faults that change when the lead is moved or reseated

• Confirm the appliance model and serial number against the compatibility list, as the lead is used across several Imax Xtra outputs
• Check the existing lead against alternative number 1780138 before ordering
• Inspect the ignition electrode and its gasket at the same time, as a damaged electrode can mimic a faulty lead
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
