Page 18: Maintenance
MAINTENANCE FLAME INSPECTION WINDOW Combustion The optimum calibration of the burner requires an analy- sis of the flue gases. Significant differences with respect to the previous measurements indicate the points where more care should be exercised during maintenance. Gas leaks Make sure that there are no gas leaks on the pipework between the gas meter and the burner. -
