WARNING
1. Press the "On/Off" button on the controller to start the unit. The LED display will illuminate, the
combustion fan will begin to run if water is flowing, and the spark will ignite the main burner.
2. This water heater has an automatic ignition system. When the main burner has lit, the "In Use"
lamp will glow red and the spark will stop.
3. Check that the burner flames are operating normally. The flame can be seen through the circular
window above the burner. When operating normally, the burner flame should burn evenly over
the entire surface. The flame should be clear, blue and stable. A yellow flame is abnormal and
maintenance is required (Figure 16).
