What it is
The Sime 6174816 is a gasket for the fan flange on Sime gas boilers. It seals the joint at the fan mounting flange, preventing flue gas leakage and air ingress at that connection. It is listed under gas boiler spares in the O-rings, washers and gaskets category.
Signs this part needs replacing
- Visible cracking, hardening or flattening of the gasket material
- Soot staining or discolouration around the fan flange joint
- Whistling or audible leakage at the fan mounting flange
- Combustion readings drifting from the values recorded at commissioning
- Traces of condensate or flue gas smell around the fan assembly
Before you order
- Confirm your boiler model and part number against the manufacturer's parts list
- Check the fan flange joint is the source of the fault before dismantling
- Inspect the existing gasket for deformation or contamination once the fan is removed
- Confirm the appliance has been isolated and made safe before work begins
