Electrical Testing

 

 

This type of water heater has its own electrical generating system.

When two dissimilar metals are joined together and this joint is heated, a small, electrical current will be produced. A thermocouple uses this science.

Meter set for DC millivolt testing

Test from lower ECO (emergency cut off or energy cut off) solder joint to ground.

Note: If pilot will not stay lit, manually hold the top knob down in the pilot position. This allows gas to flow to the pilot. Light the pilot and continue to hold this knob down while conducting the test.
