The Automatic Air Vent on Your Dunkirk 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 Dunkirk systems — including models such as Q90-200, XEB, PWX — a failing automatic air vent often shows up as no heat or related symptoms. We diagnose it precisely and install the correct genuine Dunkirk part.
