7) Start the boiler using the lighting instructions on page 49. After the boiler is powered up, it should go through the following

8) Upon initial start-up, the gas train will be filled with air. Even if the gas line has been completely purged of air, it may take
several tries for ignition before a flame is established. If more than 5 tries for ignition are needed, it will be necessary to
press the reset button to restart the boiler. Once a flame has been established for the first time, subsequent calls for burner
operation should result in a flame on the first try.
9) Inspect the flame visible through the window. On high fire the flame should be stable and mostly blue (Figure 11.1). No
yellow tipping should be present; however, intermittent flecks of yellow and orange in the flame are normal.
