BGQH15HAA-1 Retrofit Gas Control System

The BGQ15 gas control system uses a solid-state electronic ignition/flame relay control to light a pilot burner by intermittent pilot spark in Natural gas applications only. Pilot gas ignites and burns during each running cycle. This system is typically used when converting a standing pilot burner application to a more fuel-efficient intermittent spark pilot system. It permits the main gas valve to open only when the pilot burner is proven to be lit. With fast response to flame loss, the BGQ15 is ideal for power vent or gravity vent heating equipment.
