ACV Gasket for ionisation electrode 557A0162

The ACV Gasket for ionisation electrode 557A0162 is a genuine ACV part used to seal the point where the ionisation electrode passes through the burner flange or combustion chamber wall. It is designed for use in ACV HeatMaster 71 and ACV Heatmaster 71 Prestige box Mono 100 systems. This gasket features original geometry fit and is not interchangeable with other variants. It ensures proper sealing to prevent air ingress or flue gas leakage, which is critical for safe and efficient burner operation.

Parts of this type are selected strictly by the dimensions of the electrode assembly and the material rating needed for the temperature at the mounting point. Before ordering, verify that the gasket matches the electrode's shoulder or the recess in the burner plate exactly. During installation, completely remove old sealing residue and ensure mating surfaces are clean and undamaged. Do not interchange with gaskets from other electrode designs unless dimensions and material are verified against the original.

When gaskets of this kind fail, they can allow false air to be drawn in or flue gas to escape, compromising combustion and potentially causing unsafe operation. Symptoms may include erratic flame sensing, burner lockouts, or visible soot or discoloration around the electrode area. Check the gasket for cracks, hardening, or deformation, and ensure it is properly seated during service.
