SPARK IGNITER / FLAME SENSOR / CONTROL TIMING

SPARK IGNITER

This water heater is equipped with a spark igniter. Do not damage the ceramic insulator. Inspect the igniter ceramic insulator for any cracks. The spark gap between the spark rod and grounding rod is 1/8".

FLAME SENSOR

This water heater is equipped with a flame sensor. The flame sensor senses flame by passing a small electric current through the flame. This type of flame sensing is also known as flame rectification. The Ignition Control is looking for a minimum current of 0.7 micro amperes for the water heater to operate.
