Definitions

  • This invention relates generally to ignition control on gas or other fuel-fired appliances and, more particularly, to an ignition control including a microprocessor safeguard for an ignition system.
  • Conventional ignition control systems used in connection with direct spark ignition gas appliances include a gas valve having an open position and a closed position, an air blower, an ignition source, a flame sensing device and a microprocessor controller.
  • the flame sensing device is operative to detect the presence of a flame within the combustion chamber of the gas appliance and generate a signal indicative of the flame status, i.e. a flame present signal or a no flame present signal.
  • the microprocessor controller oversees the ignition process, as well as controlling the operation of the air blower and positioning of the gas valve.
