What it is
The Ideal 172053 is a complete draught diverter assembly used on Ideal Commercial Concord open-flued appliances. It sits at the flue outlet and stabilises the draught through the appliance, allowing combustion products to leave safely while drawing in dilution air at the flue break.
Supplied as a complete assembly, the part carries the previous reference 8358-8502 and the alternative number 1178439. It is a gas-carrying component, so any work involving it falls under Gas Safe requirements.
Signs this part needs replacing
- Combustion readings drifting outside the expected range for the appliance, or a flue gas analyser showing spillage at the draught diverter.
- Visible corrosion, cracking or distortion of the diverter body or its fixings.
- Soot deposits or staining around the flue outlet, suggesting the draught is not being controlled correctly.
- The appliance cutting out or locking out during operation with no other obvious cause.
- Physical damage found during a routine service or flue inspection.
Before you order
- Confirm the appliance model and serial number against the compatibility list, as Concord variants use different flue components.
- Check the existing part against the previous number 8358-8502 and the alternative number 1178439 before ordering.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
