What it is
The Baxi 5122148 is a heat exchanger spacer kit, listed in the manufacturer's catalogue as a spares kit of 4 elements (shim). It sits at the heat exchanger assembly on Baxi Duo-Tec and Megaflo appliances, where the shim elements take up clearance and maintain correct seating between mating components. Correct spacing at this joint is what keeps the assembly sealed and stable in service.
Signs this part needs replacing
- Weeping or water staining around the heat exchanger joint
- Traces of corrosion or scale build-up on the shim elements
- The heat exchanger assembly will not seat correctly or pulls up unevenly
- Distortion, compression or flattening of the existing shim elements
- Reassembly after heat exchanger work where the old spacers are reused
Before you order
- Confirm the appliance model against the fit list above
- Check the serial number suffix on the data badge, as several models are listed by ending AC, BC or CC
- Compare the part number 5122148 with the manufacturer's parts list for your appliance
- Inspect the heat exchanger joint before ordering to confirm the spacers are the failed item
