Intergas Delayed Ignition

Boiler ignites with a loud bang or pop

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Incorrect ignition electrode position, Low gas pressure at ignition, Dirty burner, Slow-opening gas valve

Safety first: Turn off the boiler and gas supply. Delayed ignition can damage the appliance and flue.

Technician steps:

Inspect ignition electrode: Check gap and position relative to the burner and adjust to Intergas specifications.
Clean burner: Remove and clean the premix burner of debris and deposits.
Check gas pressure: Verify inlet and burner pressures during ignition and adjust or correct supply issues.

Do not continue to operate the boiler until a gas-safe technician has corrected the cause.
