For more details, refer to “Connect fuel lines” on page 8. Attach air tube (if not already installed) If using a flange and gasket, slide them onto the air tube. Then attach the air tube to the burner chassis using the sheet metal screws provided. See Figures 3 & 4 on pages 6 & 7 for details. Install burner nozzle (if not already installed) Make certain the nozzle is selected for the fuel unit pressure used. For applications with fuel unit pressure above 100 psig, the nozzle rated capacity will be less than the appliance firing rate. Use only the specified spray pattern unless combustion test results indicate the need for a change. Failure to use the correct nozzle size and type can result in unacceptable combustion, possibly causing severe personal injury, death or substantial property damage. 1. Remove the plastic plug protecting the nozzle adapter threads 2. Place a .” open-end wrench on the nozzle adapter. Insert the nozzle into the adapter and finger tighten. Finish tightening with a .” open-end wrench. Use care to avoid bending the burner head support legs or electrodes. See CAUTION, below. 3. If you remove the head to replace the nozzle (type “HLX” heads), carefully reconnect the head to the nozzle adapter, making sure to butt the head support to the nozzle adapter shoulder (see Figure 3, page 6). If the nozzle is already installed, remove the nozzle line assembly to verify that the nozzle size and spray pattern are correct for the application (per appliance manufacturer’s information or Beckett OEM Specification Guide, part number 6711). Verify that the electrode tip settings comply with Figure 2a or 2b. If the nozzle is not installed, obtain a nozzle of the manufacturer, capacity and spray angle specified in appliance manufacturer’s information or Beckett OEM Specification Guide, part number 6711. For conversions or upgrades, when information is not available for the application: 4. Refer to table below to select the mid-range nozzle spray angle for the head type being used. 5. Fire the burner and make sure the combustion is acceptable and the flame is not impinging on chamber surfaces. 6. If a shorter flame is needed, select a wider spray angle. If a longer flame is needed, select a narrower spray angle. 7. Either hollow or solid spray patterns may be used. If combustion results are not satisfactory with the selected spray pattern, try the other pattern. Recommended nozzle spray angles “HLX” heads 45°, 60°, or 70° nozzle “FBX” heads 60°, 70°, or 80° nozzle Use care when removing and installing oil nozzles: • Inspect the nozzle adapter before installing nozzle. If it is grooved or scratched on the sealing surface, replace the nozzle line assembly. Otherwise, oil could leak at the nozzle-adapter joint, causing serious combustion problems. • Protect the nozzle orifice and strainer when installing. If the orifice gets dirt in it or is scratched, the nozzle will not function properly. • Do not over-torque the nozzle when installing. This will cause deep grooves in the nozzle adapter, preventing a seal when a new nozzle is installed. • Use a wrench or vise to hold the nozzle adapter. DO NOT attempt to remove or replace nozzle without holding adapter. The nozzle alignment could be seriously damaged. Use a nozzle wrench that secures the adapter or use 3/4" and 5/8" open-end wrenches. • Do not squeeze the electrodes too tightly when handling the nozzle line assembly. This could change the electrode tip settings or damage the ceramic electrode insulators. • Carefully check and realign electrode tips after replacing nozzle, ensuring the electrode settings comply with Figure 2a or 2b. Check/adjust electrodes Check the electrode tip settings. Adjust if necessary to comply with the dimensions shown in Figure 2a or Figure 2b. To adjust, loosen the electrode clamp screw and slide/rotate electrodes as necessary. Securely tighten the clamp screw when finished. Figure 2a – Electrode settings – HLX Air Tube Combinations Figure 2b – Electrode settings – FBX Air Tube Combinations Servicing nozzle line assembly 1. Turn off power to burner before proceeding. 2. Disconnect copper oil connector tube from nozzle line. 3. Loosen the screw that fastens the rear access door. 4. Remove splined nut. 5. Remove the nozzle line assembly from the burner, being careful not to damage the electrodes or insulators while handling. Stop halfway to remove igniter/transformer wires. 6. To replace the nozzle assembly, reverse the above steps. “HLX” head air tubes – ...
