The Automatic Air Vent on Your Lochinvar Boiler

The automatic air vent releases air that collects at the high points of a hydronic system. Trapped air causes cold spots, gurgling, and circulation problems; a failed vent either leaks or stops venting.

On Lochinvar systems — including models such as Knight, Knight WH, Noble — a failing automatic air vent often shows up as ignition lockout or related symptoms. We diagnose it precisely and install the correct genuine Lochinvar part.
