Ideal Flow Group Kit Combi 176867

The Ideal 176867 is a flow group kit supplied for the Vogue combi range. It sits in the hydraulic section of the boiler and governs the way water is directed between the heating circuit and the domestic hot water plate heat exchanger, so it plays a direct part in hot water delivery and diverter operation. The assembly is listed by Ideal under the diverter valves and hydraulics category and is also catalogued as a flow regulator and governor component.

• Domestic hot water runs lukewarm or cold while the heating circuit continues to work normally.
• Radiators heat up when only hot water is drawn, indicating the diverter is not seating correctly.
• Hot water flow drops away or becomes erratic at the tap.
• Water weeping or staining around the flow group body or its connections.
• Repeated fault codes or lockouts linked to the hydraulic section during a hot water demand.

• Confirm the boiler model and GC number against the compatibility list, as the Vogue C26, C32 and C40 share this hydraulic layout but carry different GC numbers.
• Note the alternative part number 1782691 when cross-referencing an existing component or an older order record.
• Inspect the seals and gaskets on the flow group during removal and replace any that are compressed, hardened or damaged before refitting.
• Work on the hydraulic section should follow the manufacturer's instructions for isolating and draining the appliance.
