Check Operation - Rinnai COMBI i060C Manuel

4. Check Operation

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 flame symbol for "in
use" 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).
