Inspect/Prepare Installation Site Inspect Chimney or Direct Vent System ! WARNING Fire, Smoke & Asphyxiation Hazard y Carefully inspect the chimney or exhaust vent system. y Make sure it is properly sized and in good working condition. y Follow the instructions supplied by the appliance manufacturer.
Inspect/Prepare Installation Site Combustion air supply ! Adequate Combustion WARNING and Ventilation Air Supply Required Failure to provide adequate air supply could seriously affect the burner performance and result in damage to the equipment, asphyxiation, explosion or fire hazards. y The burner cannot properly burn the fuel if it is not supplied with a reliable combustion air source.
Inspect/Prepare Installation Site Prepare the Burner Low Firing Rate Baff e The AFG Low Firing Rate Baffle (LFRB) reduces the air flow and pressure. The LFRB is sometimes used for firing rates under 1.00 gph as listed in Table 4. Refer to the appliance manufacturer’s instructions. Do not omit the LFRB when specified. Omitting the baffle when specified or installing the baffle when not specified could result in impaired burner performance. Burner fuel unit Table 4.
Prepare the Burner 3. 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). Verify that the electrode tip settings comply with Figure 3. 4. If the nozzle is not installed, obtain a nozzle from the manufacturer, having the capacity and spray angle specified in the appliance manufacturer’s information.
Prepare the Burner Figure 4. Check/Adjust ‘Z’ Dimension for ‘F’ Heads 1-1/8” 1-3/8” ! WARNING Adjust the ‘Z’ dimension to the required specif cation. Incorrect Adjustments could cause combustion problems, carbon deposition from flame impingement, heavy smoke generation and fire hazard. y Make all adjustments exactly as outlined in the following information. Check/Adjust ‘Z’ Dimension - ‘F’ heads 1.
Prepare the Burner Figure 5. Check/Adjust ‘Z’ Dimension - L1 & L2 Heads L1/L2 heads (see Table 7 and Figure 3 for dimensions) 1. See figure above. The important “Z” dimension is the distance from the leading edge of the head to the end of the air tube. This distance for L1 & L2 heads is 1-⅜” if the tube has a straight shroud or 1-¾” if the air tube has a conic shroud. The “Z” dimension is factory set for Figure 6.

WARNING Oil Leak and Fire Hazard Figure 9. – Outside Buried Tank-Lift System Install the oil tank following applicable standards in the U.S.
Wire burner ! CAUTION Oil Supply Pressure Control Required Damage to the filter or pump seals could cause oil leakage and a fire hazard. y The oil supply inlet pressure to the burner cannot exceed 3 psig. y Insure that a pressure limiting device is installed in accordance with the latest edition of NFPA 31. y Do NOT install valves in the return line.

Burner Controls GeniSys Model 7505 Control Wiring Explosion, Fire, Scald, and Burn Hazard Fire or Explosion Hazard All heating appliances must have HIGH LIMIT protection to interrupt electrical power and shutdown the burner if operating or safety controls fail and cause a runaway condition. Can cause severe injury, death, or property damage. y The control can malfunction if it gets wet, leading to accumulation of oil or explosive oil vapors.

Burner Controls Typical Burner Wiring & Burner Sequence of Operation for R7184P Control. Refer to the appliance manufacturer’s wiring diagram for actual specifications. Figure 10. – Typical Burner Wiring 1. STANDBY. The burner is idle, waiting for a call for heat. When a call for heat is initiated, there is a 310 second delay while the control performs a safe start check. 2. VALVE-ON DELAY. The ignition and motor are turned on for a 15 second valve-on delay. 3. TRIAL FOR IGNITION (TFI).
Wire burner Some Thermostats Are Polarity Sensitive. Reversed polarity could cause erratic cycling of the burner control. 3. Set the thermostat substantially above room temperature. 4. Close the line voltage switch to start the burner. If the burner does not start immediately you may have to reset the burner primary control. 5. Initiate a call for heat. 6. After the burner starts, press and hold the reset button for 15 seconds until the yellow light turns on.
Startup/Checkout Startup / Checkout ! 4. After the 60 second recycle period, the control will try to restart the system. WARNING Explosion and Fire Hazard 5. After the 15 second lockout time, the control will lock out the burner and the reset button will flash. Verify that the burner motor and igniter are off and that the burner oil solenoid valve (if used) is not energized.
Perform regular maintenance Step 4: Recheck smoke level. It should be Zero. • This procedure provides a margin of reserve air to accommodate variable conditions. • If the draft level has changed, recheck the smoke and CO2 levels and readjust the burner if necessary Verify the nozzle is the one originally specified by the appliance manufacturer and replace the nozzle with one having the exact specifications from the same manufacturer.
Perform regular maintenance Replace the blower wheel: 1. Turn off all power to the burner before servicing. 2. Disconnect the burner motor wires. 3. Remove the bolts securing the motor to the burner housing. 4. Remove the motor and blower wheel. 5. Remove the existing blower wheel. 6. Referring to the figure below, slide the new blower wheel onto the shaft. y Use a feeler gauge to set the wheel-to-motor gap, as shown below. (AF = 0.125 +1/64 inch, AFG = 0.
