5) Holding the air tube cover in its proper location start the burner. 6) When the solenoid valve is engaged approximately 10 seconds after starting, remove the air tube cover and shine a light source on the photocell, allowing it to see false light. 7) Run the burner until the fuel pump has been purged of air, then tighten the bleeder valve and immediately shut down the burner. 8) Reinstall the air tube cover and nozzle line. 9) The burner can now be started normally. WARNING: Omitting steps 2 and 3 will result in a collection of unburned oil in the combustion chamber creating a hazardous situation upon burner startup. B) TWO LINE (LIFT SYSTEM) Turn off the main power source to the burner and remove the air tube cover. Shines a light source on the photocell (now visible where the air tube cover was removed), return power to the burner and activate the burner. With the light source in place, the burner will operate in prepurge only. Once the burner is purged, turn off the power source and replace the air tube cover. Return power to the burner. The burner is now ready to operate. SETTING THE AIR ADJUSTMENT PLATE A) The initial air damper setting is made by turning screw (2) until the top edge of the air damper (3) is aligned with the number according to the burner setup chart. B) Further adjustments can be made with the burner cover in place by removing plastic plug on the top right hand side of the cover. Turn the screw counter clockwise (+ indicator) to increase combustion air, turn the screw clockwise (- indicator) to decrease combustion air. C) The final position of the air damper will vary on each installation. Use instruments to establish the proper settings for maximum CO2 and a smoke reading of zero. NOTE: Variations in flue gas, smoke, CO2, and temperature readings may be experienced when the burner cover is put in place. Therefore, the burner cover must be in place when making the final combustion instrument readings, to ensure proper test results. ATTENTION: It is important that the fuel line be completely sealed and free from air leaks or any internal blockages. WARNING! WHEN THE BYPASS PLUG IS INSTALLED, A TWO-PIPE SYSTEM MUST BE USED OR FAILURE OF THE PUMP SHAFT WILL OCCUR.

(1.3 ohm ± 10%) • No oil supply - tank empty, valve closed, dirty filter, damaged supply lines. • Defective or dirty oil valve stem, nozzle or pump strainer. • Broken pump drive key, defective pump, no oil pressure. • Ignition electrodes shorted, cracked porcelain. • Burner motor not up to speed. • Excessive draft over fire. • Defective control box / Replace. Reset Control Box Burner Doerner Starts Bus Not Start Test for 120Vac Supply at sub-base between L(P) & N or terminals #3 & 5 120 Vac No Voltage • Check system fuse, ensure service switch is ON. • Verify all control limits are closed. • If using switching relay - verify 24Vac at T-T. Turn off power supply - Remove control box and jumper terminals #5 & 6. Restore power. Motor Runs Motor Does Not Run • Verify electrical connections. • Check for seized pump, motor, or fan against housing. • Defective motor capacitor. • Thermal overload (Hot motor). • Verify reduced voltage (42-52 Vac) between terminals #3 & 7. • Ensure good contact between control box spades and sub-base terminals. • Defective control box / Replace. Burner stays in Pre-purge • Faulty CAD cell or seeing light before trial for ignition. • Coil wire on terminals #1 & 2 or #1 & 8 reversed. • Open coil circuit, terminals #2 & 8. • Open coil circuit, terminal #1 (530 SE only). • Open coil circuit, terminal #1 (483 SE only) will cause burner to cycle normally, but burner will lockout. • Defective 42-52 Vac supply - Terminals #3 & 7. • Defective control box / Replace.
