This Burnham Commercial Gas Control is designed for four-section Electronic Ignition (EI) systems using Natural Gas (NAT). The unit measures 1 inch in size, making it compact and suitable for various applications. It is engineered to regulate the flow of gas in a heating system, ensuring optimal performance and efficiency. The control's primary function is to safely distribute natural gas to the burner, while its electronic ignition feature eliminates the need for a standing pilot light. This results in energy savings and improved operational reliability. The four-section design indicates that this control can manage up to four separate heating zones or circuits, providing flexibility in managing different heating needs within a single system.
