The Gas Valve on Your Dunkirk Boiler

The gas valve regulates the flow of natural gas or propane to the burner and, on modulating boilers, continuously adjusts it to match demand. A faulty gas valve causes ignition failures, no heat, or unsafe combustion, and is a safety-critical component that must be tested and set by a licensed technician.

On Dunkirk systems — including models such as Q90-200, XEB, PWX — a failing gas valve often shows up as no heat or related symptoms. We diagnose it precisely and install the correct genuine Dunkirk part.
