What it is
This is a flange gasket for Firebird RDB1 and RDB2 oil boilers, listed under Firebird part codes 3513105, 3513205 and 3513605. It seals the burner flange joint on the appliance, preventing oil and combustion gases from escaping at the mounting face. The gasket is manufactured by Firebird for use across the Combi and HEAT-PAC oil boiler ranges.
Signs this part needs replacing
- Visible oil weeping or staining around the burner flange joint
- A hardened, brittle or compressed gasket that no longer seals when the burner is refitted
- Combustion smell or traces of flue gases at the burner mounting face
- Gasket torn, split or delaminated on inspection during servicing
Before you order
- Confirm the boiler model against the fit list above before ordering
- Check the part code on the existing gasket or in the appliance documentation
- Inspect the flange faces for pitting or distortion, as a damaged face will not seal with a new gasket alone
- Have a suitable replacement flange gasket to hand before removing the burner, as the old one should not be reused
