What it is
The draught diverter is the flue component fitted at the outlet of an Ideal Commercial Concord boiler, where it stabilises the draught through the flue and helps keep combustion products moving safely away from the appliance. This is the complete assembly, listed by Ideal under part number 172059 and previously referenced as 8358-8508. It is a gas-carrying flue part, so it sits within the combustion circuit rather than the water side of the boiler.
Signs this part needs replacing
- Visible corrosion, cracking or distortion on the diverter body or its flue spigot
- Soot staining or condensate tracking around the diverter joint with the boiler casing
- Combustion readings that drift outside the expected range and cannot be corrected by normal servicing
- Unstable flame picture or repeated lockouts traced to poor flue draught
- Physical damage found during an annual service or flue inspection
Before you order
- Check the appliance model and serial number against the compatibility list, as Concord variants use different flue arrangements
- Confirm the number on the part being removed matches 8358-8508 or 172059
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
