The Rinnai Air Vent (808000052) is a genuine OEM replacement component for i-Series Plus combination boilers. Air trapped in the water circuit can cause noise such as gurgling or banging, reduced heat transfer efficiency, and component damage from cavitation. The automatic air vent continuously releases trapped air from the hydraulic system without manual intervention. Replace a faulty or leaking air vent to maintain proper hydraulic system function and quiet, efficient operation.
