Section: Prepare Before Installing Prepare Before Installing General Specifications Capacity ‘F’ Head Firing rate: 1.75 – 5.50 GPH Input: 245,000 - 770,000 Btu/h Fuels USA: No. 1 or No. 2 diesel fuel or kerosene; No.1 or No. 2 heating oil (ASTM D396) Owner’s Responsibility Incorrect installation, adjustment, and use of this burner could result in severe personal injury, death, or substantial property damage from fire, carbon monoxide poisoning, soot or explosion.
Section: General Information & Nozzle Assembly Maintenance General Information Your burner was designed, installed and adjusted at the factory prior to shipment and should not require additional adjustments. Refer to the Troubleshooting section of this manual when experiencing a possible fault condition.
Section: Nozzle Assembly Maintenance Correct Nozzle and Flow Rate Required Incorrect nozzles and flow rates could result in impaired combustion, underfiring, over-firing, sooting, puff-back of hot gases, smoke and potential fire or asphyxiation hazards. Use only nozzles having the brand, flow rate (gph), spray angle and pattern specified by the appliance manufacturer. Follow the appliance manufacturer’s specifications for the required pump outlet pressure for the nozzle, since this affects the flow rate.
Section: Nozzle Assembly Maintenance C. Igniter Maintenance The igniter assembly does not require any adjustments beyond making sure the springs and the burner electrode rods make solid contact when the igniter is in the closed position. The sealing surfaces of the gaskets should be checked and replaced at the first signs of any damage or deterioration. Clean any dirt or residue from the porcelain bushings, springs, and baseplate.
Section: Fuel Supply & Burner Wiring Fuel Supply A. Connect Fuel Lines For oil supply system specifications for tanks not mounted on machines, carefully follow the pump manufacturer’s literature and the latest edition of the National Fire Protection Association (NFPA) 31 standard. The burner may be equipped with a single stage pump.

Section: Start Up Burner & Set Combustion B. Pump Maintenance General Pump Information Important information - Long or oversized inlet lines may require the pump to operate dry during initial bleeding period. In such cases, the priming may be assisted by injecting fuel oil in the pump gear set. Under lift conditions, lines and fittings must be air tight. To assure this, “Pipe Dope” may be applied to both the used and unused inlet and return fittings.
Section: Start Up Burner & Set Combustion B. Combustion Set-up Explosion and Fire Hazard Failure to follow these instructions could lead to equipment malfunction and result in heavy smoke emission, soot-up, hot gas puff-back, fire and asphyxiation hazards. y Do not attempt to start the burner when excess oil has accumulated in the appliance, the appliance is full of vapor, or when the combustion chamber is very hot.
Section: Maintain & Service Burner Maintain & Service Burner A. Owner’s Information Refer to the Replacement Parts exploded view for part locations. □ Replace the oil supply line filter if applicable. The line filter cartridge must be replaced to avoid contamination of the pump and nozzle. Have your equipment inspected at regular intervals by a qualified service agency to assure continued proper operation. The burner should be adjusted using dedicated combustion test equipment.
Section: Troubleshooting Troubleshooting Oil burners that are designed for use in pressure washers are built to take temperature extremes, vibration, and rough handling. When performing the following troubleshooting steps, we assume that the oil burner motor and ignition transformer operate continuously and the oil solenoid valve, which controls oil flow, is cycled by the trigger in the wand. We also assume that there is power to the burner and fuel in the tank.
Section: Troubleshooting Table 3. Troubleshooting Chart Symptom Possible Cause If the burner is not igniting, the burner motor, drive coupling, and oil pump are operating and oil is flowing to the nozzle through the solenoid valve, check the following possibilities. Oil Not Igniting 1. Check the air shutter adjustment. If the air shutter is opened too far, the flow of air may prevent the arc from reaching the oil spray. This may appear as a white vapor exhaust from the heater.
