  • Page 13: Norton Ignition System

    Operation of the Norton Ignition System OPERATION OF THE Power to the ignition system is 120 volts. It is rated voltage or on higher voltage machines the 120 volts is from a transformer. The ignition system is NORTON IGNITION powered through a timer or coin meter and a thermostat which calls for heat. SYSTEM The two gas valves are plumbed into a single gas line and both must open before the gas can flow into the burners.
  • Page 14 Operation of the Norton Ignition System FIGURE 2 NORTON IGNITION SYSTEM Figure 2 (Start of Cycle) Step #2 The Ignition Relay closes now and the Relay Coil stays energized by being powered through the normally open (NO) contacts of the Ignition Relay which close before the NC contacts open. The operating gas valve still has the 120 volts applied to both sides of the gas valve and the valve stays closed.
  • Page 15 Operation of the Norton Ignition System FIGURE 3 NORTON IGNITION SYSTEM Figure 3 (About 20 Seconds Later) Step #3 The Ignition glows red hot, which causes the Radiant Sensor to open its NC Contacts, which de- energizes the Igniter. As the Radiant Sensor NC Contacts open, the 120 volt to one side of the operating Gas Valve Coil is removed and an electrical circuit is formed through the NO Contacts of the Ignition Relay, through the Gas Valve and through the Igniter, and the Gas Valve opens.
