Turn on the power, start the burner motor, and sparks are generated between the ignition electrodes. After pre-blowing, the oil pump solenoid valve automatically opens, and the oil mist sprayed from the nozzle is broken down by the sparks and ignited to form a flame. At this time, the flame detector senses the brightness of the flame and the controller enters the locking state. The ignition electrode delays ignition and then stops ignition, and the burner enters normal working condition. If ignition fails, no flame is formed, or the flame detector does not sense the brightness of the flame, after the safety time has elapsed, the safety alarm system will activate, the start-up process of the burner will be cut off, and the fault red light will light up. When the burner is just started, if the flame detector has sensed the brightness, the safety system will act, the controller will not enter the normal program, the solenoid valve will not open, the nozzle will not inject fuel, and after the safety time, the fault red light will turn on. Therefore, when starting the burner in a bright place, you must first cover the flame detector to prevent it from being exposed to light. After the burner emits flame, immediately release the flame detector, otherwise the burner will not work properly. The burner can be restarted only after the red light of the burner lights up for 3 minutes.
When connecting peripheral circuits to automatically control boiler temperature, pressure, water level, etc., please follow the control system wiring diagram. The oil suction pipe must not be close to the bottom of the fuel tank and should be kept at a distance of 80-120m. The burner should be turned off before filling the fuel tank. The fuel can be injected into the fuel tank after being filtered. It can be restarted after 20 minutes of filling. The oil system must not leak oil or air. Check whether there is enough fuel in the fuel tank before starting the burner. The size of the damper should match the nozzle specifications. When the burner is used, since the boiler it is equipped with is inconsistent with the boiler used for debugging when the burner leaves the factory, it is generally necessary to adjust the damper appropriately, and sometimes it is necessary to replace the nozzle with appropriate specifications and injection angles. The ambient temperature of the burner must not exceed 70°C, otherwise cooling and heat insulation measures should be taken. When used in colder areas, appropriate insulation measures should be taken for the oil storage device and oil supply and return pipeline system to prevent the oil pipeline from freezing and clogging. At the same time, the control circuit part of the burner must not be exposed to moisture or high temperature. Turn off the burner when sweeping the chimney. The motor and ignition transformer should be protected from moisture to avoid use in humid environments. The burner should be balanced when installed. It should be used horizontally or vertically and avoid tilted use. When it is inconvenient to directly operate the burner, external control switches and electrical protection devices should be connected. Frequently check whether the connection of the burner and its components is firm, loose, and whether the position has changed. When the burner is started, be careful not to injure people or damage objects due to the sudden burst of flames.
The light diesel oil used must be clean. Please pay attention to cleaning the fuel tank and oil filter regularly. Under normal use, replace the oil nozzle once a year, and replace the elastic coupling and the rubber parts on the coupling once a year and a half. It is strictly forbidden for foreign objects to enter the air duct. The site where the burner is used should be kept away from flammable and explosive materials, and fire extinguishing equipment should be available. Adjust the oil pressure appropriately according to the oil pressure indication value. Regularly check the combustion tube, impeller, flame detector and ignition electrode to remove oil stains and carbon deposits. Especially the flame detection equipment. The detector should be kept clean and not exposed to water.
Be sure to cut off the power supply when maintaining the burner
