· 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 2. 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 fl ow. Such debris will prevent proper operation of the burner. Refer to local codes for proper location of inlet. • The burner cannot properly burn the fuel if it is not supplied with a reliable combustion air source. Follow the guidelines in the latest editions of the NFPA 31 and CSA-B139 regarding providing adequate air for combustion and ventilation. • • Failure to provide adequate air supply could seriously affect the burner performance and result in damage to the equipment, asphyxiation, explosion or fi re hazards.

Tape fragments can lodge in fuel line components and fuel unit, damaging the equipment and preventing proper operation. Use oil-resistant pipe sealant compounds. •• • Damage to the pump could cause impaired burner operation, oil leakage and appliance soot-up. ! CAUTION Do Not Use Tefl on Tape • Fuel Line Installation Inspect/Prepare Installation Site Figure 3. – Mounting Burner in Appliance Prepare the Burner General In most cases, the burner is ready to mount to the appliance. There can be situations where the burner needs to be reconfi gured to perform properly in the appliance. Review the appliance manufacturer’s specifi cations prior to installing to determine if any modifi cation is required to properly confi gure the burner. Instruction on how to perform the following burner preparation tasks can be found in the Professional Maintenance section. Remove / install burner nozzle Check head/air adjusting plate Mount Burner on Appliance Verify that the air tube installed on the burner provides the correct insertion depth. Refer to Figure 3. The end of the air tube should normally be 1/4” back from the inside wall of the combustion chamber. Never allow the leading edge of the retention ring to extend into the chamber, unless otherwise specifi ed by the appliance manufacturer. Bolt the burner to the appliance using the factorywelded fl ange. • •• • To further protect the fuel supply system and reduce nozzle orifi ce plugging with fi ring rates below 0.75 gph, a dual fi ltration system can be installed. This typically consists of a 50 micron primary fi lter, located near the fuel tank and a secondary fi lter rated for at least 10 microns located near the burner. NOTICE For protection in the event of fi re, some states require the shutoff valves to be a fusible-handle design. R.W. Beckett Corporation recommends this design as good industry practice for all installations. NOTICE For fuel line installation, continuous lengths of heavy wall copper tubing are recommended. Always use fl are fi ttings. Never use compression fi ttings. Always install fi ttings in accessible locations. To avoid vibration noise, fuel lines should not run against the appliance or ceiling joists. Fuel Line Valves and Filter Install two high quality oil duty rated 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 fi lter. • Also install a generous capacity fi lter, rated for 50 microns or less, inside the building between the fuel tank shutoff valve and the burner. Locate both the fi lter and the valve close to the burner for ease of servicing. 3GPH150-200 PSI 3450RPM 4GPHGPH100-150 100-PSI 3450 3450RPM RPM BY-PASSINLET A2EA-6520 NO.2&LIGHTERFUEL ExclusivelyforBeckett NO.2 FUEL MadebySuntec INLET Beckett USEUSEONLY ONLYWITHWITH VALVEONDELAY Start the Burner and Set Combustion • Connect Fuel Lines WARNING!

The burner is supplied with either a one-stage pump or a two-stage pump based on the oil supply system requirements. Consult the instructions provided with the pump for installation specifications. !!CAUTION Oil Supply Pressure Control Required Damage to the filter or pum...
