Slant Fin 412-705-040 Damper Assembly R-410A it includes high-tolerance internal partsThe Slant Fin 412 705 040 is a heavy duty 5 inch automatic vent damper assembly engineered specifically for high efficiency hydronic heating systems. Designed as a direct replacement component, this motorized flue damper prevents standby heat loss by sealing the vent pipe when the burner is not firing, significantly improving the AFUE rating of the boiler. This assembly features a robust internal synchronous motor and built in safety interlock
