Ideal / Keston System 30 Flue Manifold – Pre-Owned | Part No. 175940

The flue manifold is a critical safety-critical component in any condensing boiler — it channels combustion exhaust gases safely from the heat exchanger to the flue outlet. When it cracks, corrodes, or becomes blocked, the boiler may present flue fault codes (F3, F4, or related ignition/flue gas errors) and enter safety lockout. The Ideal 175940 Flue Manifold is the genuine Ideal Heating replacement for the Keston System 30 boiler (GC No. 41-930-39), restoring safe and efficient flue gas management and returning the boiler to normal operation.

This is a genuine pre-owned Ideal component — inspected and verified functional before dispatch. Condition is refurbished/pre-owned; minor cosmetic marks may be present consistent with removal from a working boiler. Original price: £59.99 — current sale price: £44.99. Supplied with a full 12-month warranty.
