Page 5: Matters To Be Attended For Safety
Matters to be attended for safety ■ Before installing, trial-operating, maintaining or inspecting this burner,please learn the inside of this burner, in- formation of safety and other matless to be attended by reading this instruction manual and all of attached doc- uments. -
Page 6: Read Without Fail
Read without fail ■ Never fail to exhaust the air in the farnace (pr-purge) before igniting. Repeated ignitions may cause explosion due to the gas stagnated in the furnace. Please install safety devices like a flame supper visor. Never fail to cut the electricity of transformer when you take off the ignition plug in order to check the spark of it. -
Page 7: Air Piping
Air Piping ■ 1. Minimize pressure loss due to piping resistance. For the piping up to the burner, secure the connection diameter equal to or larger than the specified connection diameter. Set the air rate within the main air piping to around 10m/sec. 2. -

Operation ■ 1. Preparation for operation Fully open the air butterfly damper. Confirm that the oil control handle is in the scale “ ” position, and ① fully open the stop valve at the oil inlet. (Loosen the fixed butterfly nut behind the burner beforehand.) Open all the stop valves of the oil piping, and fully open the return valve of the oil feed pump. -
Page 10: Automatic Control
■ 1. Outline HOPE YLP TYPE PROPORTIONING OIL BURNER can proportionally control the air quantity and the oil quantity simultaneously only through the operation of the air control handle and the oil control handle, respectively. Therefore, automatic control can be performed easily by using an electric motor or the like. -
Page 11: Disassembly
Disassembly ■ a) Disassemble the reducing valve and the oil strainer at the union joint. b) Loosen the hexagon socket setscrew from the burner support, remove the fixing bolt of the flange ⑩ and remove the burner. c) Remove the hexagon socket head cap screw from the oil valve body , and take out the oil regulator ⑪... -

Cleaning. Assembly ■ a) Clear the sliding portion between the oil control spindle and the oil valve body of foreign objects to protect the portion from flaw. b) Clear the burner of carbon and others. c) Apply sealing agent to the threaded portion of the oil nozzle and the oil valve body, and fasten them completely. -
Page 13: Maintenance And Inspection. Warning Plate
Maintenance and inspection ■ 1.Clean the burner body and its accessories according to the fuel type and operation frequency. 2.If the atomizer of the burner body, the oil nozzle and the burner tile are contaminated with carbon and dirt and dust, combustion effect is degraded. Clean them periodically. 3.The air control handle may become heavy in operation due to the adherence of dirt and dust to the inside of the burner body and radiation heat. -

Page 18: Technical Data (Air Pipng. Pressure Loss)
3.Air Piping The important role of the air piping is to minimize pressure loss. If pressure loss is large, it is difficult to maintain the inner pressure of the burner to a constant level. Therefore, control the total pressure loss to 0.7 to 0.8kPa.
