This Suburban 525011 kit includes the correct electrode gasket and burner gasket used on Suburban RV furnaces. These gaskets seal the electrode mounting plate and burner interface, preventing combustion‑air leaks that can cause ignition issues, flame instability, or lockouts. Any time an electrode is replaced or removed, Suburban specifies replacing these gaskets to maintain proper combustion‑chamber sealing.

The kit is a direct replacement for 072102, which appears in older service manuals and parts lists.
