Ideal Flow and Return Header Super Plus 300/400 136099

The Ideal 136099 is a flow and return header for Ideal Commercial Super Plus 300/400 boilers. It forms part of the appliance's water circuit, collecting and distributing flow and return water between the boiler's internal pipework and the system connections. The header is supplied as an Ideal Commercial boiler spare and is also identified by the alternative number 1176453. Headers of this type are replaced when the original develops a leak or becomes restricted, as both faults affect circulation through the appliance.

• Water weeping or visible leaks around the header body or its connections
• Corrosion, pitting or heavy scale build-up on the header
• Uneven heating or hot spots across the boiler sections
• Frequent pressure loss and the need to top the system up
• Kettling or knocking noises from the boiler during operation

• Check the GC number on the appliance data badge; this header is listed against GC 41-415-68 and 41-415-69
• Confirm the appliance is a Super Plus 300/400 variant before ordering
• Cross-reference the alternative number 1176453 if you are working from older documentation
• Have the appliance model and serial number to hand when checking the compatibility list
