Description
Navien OEM Space Heating Strainer Assembly
The Navien 30002513D is a genuine OEM space heating (S.H.) strainer assembly designed as a direct replacement for compatible Navien condensing boiler and combination heating systems. Keeping the strainer assembly in proper working condition is essential to protecting internal components from debris, sediment, and particulate buildup that can restrict flow and reduce system efficiency.
Why Replace Your Strainer Assembly?
Over time, strainer screens can become clogged or damaged, leading to reduced water flow, increased pressure drop, and potential damage to downstream components such as heat exchangers and pumps. Replacing with a genuine Navien OEM part ensures a precise fit and restores full system performance.
