Section: Prepare Before Installing Prepare Before Installing 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. Contact a professional, qualified service agency for the installation, adjustment and service of your oil heating system.
Section: General Information Adequate Voltage Required A low or erratic power supply could result in impaired burner operation, severe delayed ignition or an explosion inside the heat exchanger resulting in a burn and/or asphyxiation hazard. y The Model ADC requires a continuous supply of 11 to 16 volts DC at 15 amps measured at the burner during operation.
Section: Nozzle Assembly Maintenance E. Low Firing Rate Baffle. The low firing rate baffle (See LFRB in Replacement Parts) reduces the air flow and pressure. The LFRB is sometimes used for firing rates under 1.00 gph as listed in Table 1. Refer to the equipment manufacturer’s instructions. Do not omit the LFRB when specified. Omitting the baffle when specified or installing the baffle when not specified could result in poor burner performance.
Section: Nozzle Assembly Maintenance B. Check/Adjust Electrodes Check the electrode tip settings. Adjust if necessary to comply with the dimensions shown in Figure 2. To adjust, loosen the electrode clamp screw and slide/rotate electrodes as necessary. Securely tighten the clamp screw when finished. 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.
Section: Fuel Supply The Beckett Z gauge (part number Z2000) is available to permit checking the F head “Z” dimension without removing the burner. Fuel Supply C. Fuel Supply Below Level of Burner When the fuel supply is more than eight feet below the level of the burner, a two-pipe fuel supply system is required. Depending on the fuel line diameter and the horizontal and vertical length, the installation may also require a two-stage pump.

Section: Drive Component Maintenance B. Pump Maintenance To check pump operation perform the following. 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 Igniter with Interrupted Duty Ignition - This optional control circuit is available to reduce current draw on the charging system by turning the igniter off after a flame has been established. This option controls igniter operation based on a signal from a light sensing cad cell. When light hits the cell the control will sense a decrease in resistance across the sensor. A few seconds delay will occur prior to the igniter switching off.
Section: Maintain & Service Burner Maintain & Service Burner A. Owner’s Information Professional Service Required 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. Please read and understand the manual supplied with this equipment.
Section: Troubleshooting □ Clean the cad cell, if applicable. □ Make sure Low Firing Rate Baffle is in place, if required, for the burner application. Omitting the baffle can result in unacceptable burner combustion. □ Inspect all gasket including the igniter base plate Table 2. Nozzle Flow Rate by Size Nozzle flow rate U. S. gallons per hour of No. 2 fuel oil when pump pressure (psig) is: Nozzle Size (rated at 100 psig) 125 psi 140 psi 150 psi 175 psi 200 psi exceed the nameplate rating.
Section: Troubleshooting Table 4. 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.
