Technical Insight & Common Servicing Requirements

The combustion chamber gasket provides a secure seal around the combustion area, helping prevent combustion gases from escaping and maintaining safe operation.

The ignition electrode generates the spark required to ignite the burner, while the ionisation electrode detects the presence of a flame and communicates this information to the boiler control system. If flame detection is unsuccessful, the boiler safety system can interrupt operation.

The additional service components included within the kit are designed to support routine boiler maintenance and replacement of commonly worn parts.

Typical reasons for replacing these service components include:

• Routine boiler servicing
• Ignition problems or unreliable starting
• Flame detection faults
• Boiler locking out during ignition
• Worn or damaged combustion seals
• Preventative maintenance requirements
• Maintaining safe and efficient boiler operation

Replacing these components during servicing may help restore reliable ignition, correct flame monitoring, and efficient boiler performance.
