Further details
| Application context | seals the burner-heat exchanger joint, ensuring safe and efficient boiler operation |
|---|---|
| Key benefits | Leak-proof seal, wear resistance, factory original quality |
| Material composition | EPDM, silicone, graphite or fibre (material depends on temperature and medium rating) |
| Material function in system | contains water, gas and flue gases within their intended circuits, and protects precision components from contamination or leakage |
| Replacement selection criteria | must match original in shape, thickness, material grade, and for a kit, the exact assembly series |
| Risks of incorrect replacement | incorrect seal can lead to leakage, combustion imbalance, or safety hazard |
Choosing and fitting
When selecting a replacement burner gasket, confirm that the new part matches the original in shape, thickness, and material grade. Common gasket materials include EPDM, silicone, graphite, and fibre, chosen for temperature and medium compatibility. Gaskets are typically located at flanged joints, such as between the burner and boiler front plate. For kits, the replacement must match the exact valve or regulator series; it is not interchangeable with other series.
Signs of failure
Failed or worn gaskets allow gas or water to escape from the burner-heat exchanger joint, causing visible leakage, reduced boiler efficiency, or flame instability. The equipment may show pressure drops, difficulty maintaining ignition, or pooling fluid near the burner base. Inspect the joint for moisture, soot, or corrosion; a damaged gasket typically shows visible cracking, hardening, or separation from its seat.
