Pressure is 140 psig unless otherwise noted. • • • Underwriters Laboratories has certified this burner to comply with ANSI/UL 296 and has listed it for use with #1 or #2 fuel oil as specified in ASTM D396. Low sulfur #1 and #2 fuel oils reduce heat exchanger deposits with all burners compared to the standard fuels. Reduced deposits extend the service interval for cleaning and improve the efficiency of the appliance over time. Low sulfur fuels reduce particulate and oxides of nitrogen emissions as well. The Oilheat Manufacturers' Association recommends these fuels as the preferred fuels for this burner. State and local approvals are shown on burner rating label (see below). All oil burners should be installed in accordance with regulations of the latest revision of the National Fire Protection Association Standard NFPA 31 and in complete accordance with all local codes and authorities having jurisdiction. Regulation of these authorities take precedence over the general instructions provided in this installation manual. For recommended installation practice in Canada, refer to the latest version of CSA Standard B139. Notice special requirements DANGER This equipment must be installed, adjusted and started only by a qualified service agency – an individual or agency, licensed and experienced with all codes and ordinances, who is responsible for the installation and adjustment of the equipment. The installation must comply with all local codes and ordinances and with the latest revision of the National Fire Protection Standard for Oil-Burning Equipment, NFPA 31 (or CSA B139). WARNING Read all instructions before proceeding. Follow all instructions completely. Failure to follow these instructions could result in equipment malfunction, causing severe personal injury, death or substantial property damage. Concealed damage — If you discover damage to the burner NOTICE or controls during unpacking, notify the carrier at once and file the appropriate claim. NOTICE When contacting Beckett for service information — Please record the burner serial number (and have available when calling or writing). You will find the serial number on the silver label located on the top right of the burner, to the left of the air dial. See illustration below. SK9642 3 Beckett Instruction Manual – Model AFII Oil Burner Prepare burner & site Inspect/prepare installation site Inspect/prepare installation site (continued) Chimney or vent Exhaust fans and other air-using devices • • Inspect the chimney or vent, making sure it is properly sized and in good condition for use. For those installations not requiring a chimney, such as through-the-wall vented appliances, follow the instructions given by the appliance and power venter (if used) manufacturers. Size air openings large enough to allow for all air-using devices in addition to the minimum area required for combustion air. If there is any possibility of the equipment room developing negative pressure (because of exhaust fans or clothes dryers, for example), pipe combustion air directly to the burner. Direct air supply and sidewall venting • • When sidewall venting appliances, carefully follow appliance and power venter instructions for installation and wiring. AFII burners are equipped with a removable air inlet to allow use of a 4” duct to supply outside air for combustion. Do not exceed 70 equivalent feet. Allow 6 feet for each elbow. 1. Remove the inlet cover. 2. Insert 4" duct into the inlet ring. 3. Fasten duct into place using at least 3 sheet metal screws evenly spaced around the inlet ring. Refer to Figure 1. 4. Remove the barometric draft control unless it is in the same atmospheric pressure zone as the inlet. On the outside of the home use a 90° elbow pointed downward with a 1/4" mesh screen over its opening. The air inlet elbow must be located above the snow line and in such a way as to prevent leaves and/or other debris from blocking the air flow. Such debris will prevent proper operation of the burner. Refer to local codes for proper location of inlet. Figure 1 – Outside air connection 4 IN. DUCT AIR INLET ELBOW Clearances to burner and appliance • Provide space around burner and appliance for easy service and maintenance. • Check minimum clearances against those shown by the appliance manufacturer and by applicable building codes. Combustion chamber — Burner retrofitting Verify that the appliance combustion chamber provides at least the minimum dimensions given in Table 2. CAUTION When retrofitting an appliance that has an unlined stainless steel combustion chamber, chamber burnout could result from the use of a high performance burner. Protect the chamber from high temperatures through the use of "wet-pac" or a similar ceramic liner. Some equipment may utilize a stainless steel combustion chamber that has been designed and tested by the manufacturer for use with a flame retention burner, therefore ceramic protection would not be necessary. Refer to appliance manufacturer’s instructions. Failure to comply could result in damage to heating equipment. Table 2 – Minimum combustion chamber dimensions Chamber dimension (inches) ¼” MESH SCREEN INLET RING SK8810 Combustion air supply See NFPA Standard 31 for complete details. WARNING If the burner is not supplied with a reliable combustion air source, the burner cannot properly burn the fuel. This would result in incomplete combustion, causing sooting and possible emission of carbon monoxide. Severe personal injury, death or substantial property damage could occur. Appliance located in confined space The confined space should have two (2) permanent openings: one near the top of the enclosure and one near the bottom of the enclosure. Each opening shall have a free area of not less than (1) one square inch per 1,000 BTU’s per hour of the total input rating of all appliances within the enclosure. The openings shall have free access to the building interior, which should have adequate infiltration from the outside. 4 Firing rate (gph) Round I.D. 0.50 Rectangular Height Floor to nozzle Width Length 8 7 8 12 5-6 0.75 9 8 9 12 5-6 1.00 10 9 10 12 ½ 5-6 1.25 11 10 11 12 ½ 5-6 1.50 12 11 12 13 6-7 Beckett Prepare burner Instruction Manual – Model AFII Oil Burner Prepare burner & site • Burner fuel unit • Verify that the burner fuel unit is compatible with the oil supply system. For more details, refer to “Connect fuel lines” on page 8. • Attach air tube (if not already 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. 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) Check/adjust electrodes WARNING 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 ¾” open-end wrench on the nozzle adapter. Insert the nozzle into the adapter and finger tighten. Finish tightening with a ⅝” 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). 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 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. SK8263 If the nozzle is not installed, obtain a nozzle of the manufacturer, capacity and Figure 2b – Electrode settings – FBX Air Tube Combinations 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 SK8811 are not satisfactory with the selected spray pattern, try the other pattern. Recommended nozzle spray angles 45°, 60°, or 70° nozzle “HLX” heads 60°, 70°, or 80° nozzle “FBX” heads 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. CAUTION • • • Servicing nozzle line assembly 1. 2. 3. 4. 5. Turn off power to burner before proceeding. Disconnect copper oil connector tube from nozzle line. Loosen the screw that fastens the rear access door. Remove splined nut. 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 – Be sure stop screw is fastened securely. Seat stop screw on back of choke ring to set the position of the head. “FBX” head air tubes – Use T gauge to set the “Z” dimension to 1-1/8” +/1/32”. 5 Beckett Instruction Manual – Model AFII Oil Burner Prepare burner & site Figure 3 - HLX Arrangement FIRING RATE Stop Screw AFII 85 AFII 100 AFII 150 0 0.40-0.65 0.50-0.65 0.75-1.00 1 - 0.60-0.75 0.85-1.10 2 - 0.65-0.80 0.95-1.15 3 0.60-0.75 0.65-0.90 0.95-1.20 4 - 0.75-0.95 1.10-1.25 5 0.70-0.85 0.85-1.00 1.15-1.35 6 - 0.95-1.10 1.15-1.40 7 - - 1.25-1.50 8 - - 1.30-1.50 Firing Rate at 140 psig AFII 85 AFII 100 0.40 to 0.65 3 - - 0.60 to 0.75 4 3 - 0.70 to 0.85 5 4 - 0.75 to 1.00 - 5 2 AFII 150 0.95 to 1.20 - - 3 1.15 to 1.35 - - 4 1.25 to 1.50 - - 5 AIR DIAL SETTING SK9644A 6 SK9639 Beckett Instruction Manual – Model AFII Oil Burner Prepare burner & site Figure 4 - FBX Arrangement FIRING RATE Head AFII 85 AFII 100 AFII 150 Firing Rate at 140 psig AFII 85 AFII 100 FB0 0.40-0.65 0.55-0.75 0.75-1.00 0.40 to 0.65 3 - - FB3 0.55-0.85 0.55-1.10 0.85-1.20 0.60 to 0.75 4 3 - FB4 - 0.75-1.10 1.10-1.25 0.70 to 0.85 5 4 - FB6 - 0.85-1.15 1.15-1.35 0.75 to 1.00 - 5 2 AFII 150 0.95 to 1.20 - - 3 1.15 to 1.35 - - 4 1.25 to 1.50 - - 5 AIR DIAL SETTING SK9644B SK9641 7 Beckett Instruction Manual – Model AFII Oil Burner Adjust, pipe, & wire burner Connect fuel lines (continued) Mount burner on appliance Mounting options • Bolt the burner to the appliance using the factory-mounted flange or an adjustable flange. Mounting dimensions • • • When using the Beckett universal adjustable flange, mount the air tube at a 2° downward pitch unless otherwise specified by the appliance manufacturer. Verify that the air tube installed on the burner provides the correct insertion depth. See Figure 5. The end of the air tube should normally be ¼" back from the inside wall of the combustion chamber. Never allow the leading edge of the head assembly to extend into the chamber, unless otherwise specified by the heating appliance manufacturer. Carefully measure the insertion depth when using an adjustable flange. Verify the insertion depth when using a welded flange. Figure 5 – Mounting burner in appliance WARNING The oil supply inlet pressure to the fuel unit cannot exceed 3 psi. Install a pressure-limiting device in accordance with NFPA 31. Fuel supply below the level of the burner When the fuel supply is below the level of the burner, a two-pipe fuel supply system is required. Depending on the fuel line diameter and horizontal and vertical length, the installation may also require a two-stage pump. Consult the fuel unit manufacturer's literature for lift and vacuum capability. Fuel line installation • • Continuous lengths of heavy wall copper tubing are recommended. Always use flare fittings. Never use compression fittings. Always install fittings in accessible locations. Fuel lines should not run against the appliance or the ceiling joists (to avoid vibration noise). WARNING Never use Teflon tape on any fuel fitting. Tape fragments can lodge in fuel line components and fuel unit, damaging the equipment and preventing proper operation. Fuel line valve and filter • Install two high quality shutoff valves in accessible locations on the oil supply line. Locate one close to the tank and the other close to the burner, upstream of the filter. NOTICE Some states require these valves to be fusible-handle design for protection in the event of fire. We recommend this as good industry practice for all installations. • Install a generous capacity filter inside the building between the fuel tank shutoff valve and the burner, locating both the filter and the valve close to the burner for ease of servicing. Filter should be rated for 50 microns or less.
