What it is
The Alpha 1.020369 is a flue connection flange seal for Alpha gas boilers. It fits at the flue connection flange joint, sealing the joint to stop flue gases and condensate escaping at that point. It is a serviceable gasket-type component used during flue assembly and repair.
Signs this part needs replacing
- Visible cracking, hardening or flattening of the seal
- Flue gas smell or leakage detected around the flue connection flange
- Condensate weeping or staining at the flange joint
- Seal deformation or damage found when the flue is dismantled
- Combustion analysis readings outside the expected range
Before you order
- Confirm your boiler model and GC number against the fitment list above
- Check that the part number 1.020369 matches the seal removed from the appliance
- Inspect the flue connection flange and mating surfaces for damage or distortion
- Check whether other seals or gaskets in the flue assembly also need replacing
