The Ideal 170950 Fan Assembly is a genuine replacement combustion airflow component designed for use in Super Ser 4 series boilers. This fan draws the correct amount of air into the combustion chamber and expels flue gases safely through the flue system, helping maintain stable ignition, efficient combustion and reliable heat output. When a fan becomes worn, noisy or begins to fail, boilers can experience ignition delays, inconsistent flame performance or safety lockouts, so fitting the correct OEM fan assembly is essential for restoring dependable and safe operation.

This fan assembly is compatible with Ideal Super Ser 4 boilers that reference part number 170950 in their parts documentation. To ensure proper fitment and optimal performance, always verify the part number on your existing fan or consult your boiler’s service information before installation, as combustion airflow components differ between models and configurations.

Supplied as spares only, the 170950 Fan Assembly is ready for direct replacement and fits into the boiler’s original mounting points and electrical connections without modification when installed by a qualified engineer. Choosing this genuine Ideal component helps restore correct combustion airflow, improves ignition reliability and supports consistent heating performance in compatible Super Ser 4 boilers.
