Appliances located in confi ned spaces: All confi ned spaces should have two (2) permanent openings; one near the top of the enclosure and one near the bottom of the enclosure. Each open ing must have a free area of not less than one (1) square inch per 1,000 BTU's per hour of the total input rating of all appliances within the enclosure. The openings should have free access to the build ing interior, which should have adequate infi ltration from the outside. Exhaust fans and other air-using devices: Size air openings large enough to supply all air-using devices in addition to the minimum size required for combustion air. If there is any possibility of the equipment room developing a negative pressure due to exhaust fans, clothes dryers, etc., either pipe combustion air directly to the burner or provide a sealed enclosure for the burner and supply it with its own combustion air supply. · When sidewall venting appliances, carefully follow appliance and power venter instructions for instal lation and wiring. · AFII burners are equipped with a removable air in let 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 met al 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.

Always use • fl are fi ttings. Never use compression fi ttings. • Always install fi ttings in accessible locations. To Maintenance section. Remove / install burner nozzle Check head/air adjusting plate Mount Burner on Appliance avoid vibration noise, fuel lines should not run against the appliance or ceiling joists. Fuel Line Valves and Filter • Verify that the air tube installed on the burner pro vides the correct insertion depth. Refer to Figure 3. 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. NOTICE For protection in the event of fi re, some states require the shutoff valves to be a fusible-handle design. R.W. Beck ett Corporation recommends this design as good industry practice for all installations. NOTICE To further protect the fuel supply system and reduce noz zle 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. 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. 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 speci fi ed by the appliance manufacturer. Bolt the burner to the appliance using the factory welded fl ange.
