Ease of Fireside Inspection - Front and rear doors are hinged and davited to provide simple opening and minimum clearance for full access to fireside tube surfaces, which eliminates the necessity of disconnecting the burner and fuel piping. Fuel Flow Control Valves - Contoured cam valves provide reliable fuel to air ratio set points from low fire to high fire assuring the best burner efficiency.
