Inspections

Burners

Clean main burners and air louvers of dust, lint and debris. Keep boiler area clear and free from com- bustibles and flammable liquids. Do not obstruct the flow of combustion and ventilation air. Make visual check of burner and pilot flame. Yellow flame indicates clogging of air openings. Lifting or blowing flame indi- cates high gas pressure. Low flame indicates low gas pressure.

Modulating burner flame varies in height from approximately 1/4" at low fire to approximately 4" at high fire.

Controls

Check all controls to see that they are operational. To check electronic safety (IID Models), turn off main burner. Observe pilot burner when shutting off pilot gas. Ignition spark should go on. Main gas valve will also drop out.

To check high limit switch, turn dial setting down to a point slightly below the temperature of the water leav- ing the heater. The reset button should snap out and the burner should shut-off. Reset dial to 30°F to 40°F above desired operating temperature, and push reset button. Burner should light.

Suggested Inspection

Schedule

The boiler should be inspected on the first and third months after initial start-up and then on an annual basis. If problems are found, refer to Troubleshooting Guide for additional directions.

1.Remove top of heater and inspect heat exchanger for soot and examine venting system.
