Ideal Boiler Fan + Ignition Electrode 172625 173528

Product Overview

The Ideal Boiler Fan & Ignition Electrode Kit (172625 & 173528) is a replacement combustion service kit designed for use within selected Ideal heating systems. 

This kit combines two important boiler combustion components. The fan assembly controls the movement of air through the combustion system, helping ensure the correct air supply for safe and efficient burner operation. The ignition electrode generates the spark required to ignite the burner, allowing the boiler to start the combustion process correctly. 

Replacing worn combustion components can help maintain reliable ignition, correct air flow, and efficient boiler operation.

Technical Insight & Common Failure Symptoms

The boiler fan is a key part of the combustion system. It creates the required airflow through the burner and flue system, allowing the boiler to safely operate and maintain correct combustion conditions. The ignition electrode works with the ignition system to produce the spark needed to light the burner. 

Over time, fans can experience mechanical wear, bearing noise, reduced performance, or electrical faults. Ignition electrodes may deteriorate due to heat exposure, contamination, or normal operation.

Typical symptoms linked to faulty fan or ignition components include:

• Boiler failing to ignite
• Boiler locking out during ignition sequence
• No spark during ignition
• Fan running noisily or inconsistently
• Combustion-related fault codes
• Boiler failing to complete the ignition process
• Reduced boiler performance

Replacing these components may help restore reliable ignition and correct combustion operation.
