Normal Operating Sequence
When pressing the ON/OFF button, the LED display
will illuminate, the combustion fan will begin to run if
water is flowing, and the sparker will ignite the main
burner.
This heater has an automatic ignition system. When
the main burner has lit, the combustion lamp will glow
red, and the spark will stop.
Check Operation
Visual Inspection of Flame
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.
