Page 5: General
General Oilon GP-6.10 P and GP-6.20 P -burners are fully automatic gas burners. The burners can be used on most heating appliances such as hot water boilers, steam boilers and air heaters. Burners are tested and certified for the following gas types ·... - Page 6 CAUTION! The burner must be installed firmly. Vibrations may damage burner or its components. CAUTION! Prior to trial start the gas piping must be vented. See chapter ”Example of an Installation of Gas Supply Line”. DANGER! In case of gas leakage: - do not make fire, do not touch the electrical equipment - close the main fuel shut-off valve outside the plant - make sure, that there is no people in the leakage area...
