Abstract
An automated gas distribution system for safely and reliably controlling the flow of gaseous fuel to gas appliances. The system implements a 'closed-loop' delivery of gas, i.e., the gas is provided to a recongnized appliance only when that appliance sends a valid request for gas to a control/communications subsystem. Certain conditions preclude the supply of gas despite a valid request for gas and include an appliance or system malfunction, or a command from the system operator instructing the system to ignore certain gas requests. In addition, emergency conditions, such as a fire or gas leak will also circumvent the closed-loop delivery of gas to appliances.
