Signs this part needs replacing
- Visible cracking, splitting or perforation of the chamber panels or C frame
- Distortion or warping of the frame after overheating
- Heavy corrosion, scale or heat discolouration across the chamber surfaces
- Damaged or pitted sealing faces where the chamber gasket seats
- Flue gas leakage, combustion readings outside tolerance or a CO alarm on the appliance
Before you order
- Confirm the appliance model and output against the fitment list above, as the WH70 appears in the Sirius 2 list
- Check whether the appliance is a Sirius 2 unit installed from April 2016 where that build date applies to your model
- Inspect the existing chamber gasket and fixings, as these are separate items and are not part of this listing
- Compare the existing chamber / C frame pattern and mounting points with the unit before fitting
