Check Operation; Check The Normal Operating Sequence; Visual Inspection Of Flame - Rinnai I Series Installation And Operation Manual

1. Check the normal operating sequence:

a. When you press the ON/OFF button, the LED display will illuminate, the combustion fan
will begin to run if water is flowing, and the spark will ignite the main burner.
b. This boiler has an automatic ignition system. When the main burner has lit, the "In Use"
lamp will glow red and the spark will stop.

2. Visual inspection of flame:

a. 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 4).
