Section: Inspect/Prepare Installation Site Inspect/Prepare Installation Site Professional Service Required Incorrect installation, adjustment, and use of this burner could result in severe personal injury, death, or substantial property damage from fire, carbon monoxide poisoning, soot or explosion. Please read and understand the manual supplied with this equipment.
Section: Inspect/Prepare Installation Site 4. No other appliance connection should be made to the same flue pipe. 5. The flue pipe should have an upward pitch toward the chimney of at least 1/4” per foot of length. It should fit tightly and should not project into the chimney. 6. Any leakage between tiles, around clean-out doors, or around the vent pipe should be sealed.
Section: Prepare the Burner Combustion chamber — Burner retrofitting ○ Verify that the appliance combustion chamber provides at least the minimum dimensions given in Table 3.

Section: Prepare the Burner Connect Fuel Lines Oil Leak and Fire Hazard Install the oil tank following applicable standards in the U.S. by referring to the latest edition of NFPA 31 or CSA-B139 & CSA-B140 in Canada, and all authorities having jurisdiction. Fuel Line Valves and Filter Do Not Install By-pass Plug with 1-Pipe System Failure to comply could cause immediate pump seal failure, pressurized oil leakage and the potential for a fire and injury hazard.
Section: Wire Burner Fuel supply below the level of the burner When the fuel supply is more than eight feet 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, included with the burner, for lift and vacuum capability. Fuel line installation ○ ○ Continuous lengths of heavy wall copper tubing are recommended.
Section: Wire Burner Wiring Connections Diagram y Follow the appliance manufacturer’s wiring diagrams and note all required safety controls. y Verify all limit and safety controls are installed and functioning correctly, as specified by the manufacturer, applicable safety standards, codes and all authorities having jurisdiction. Figure 7a.
Section: Burner Control Burner Control solenoid valve is turned off and the control delays turning the motor off for the set motor-off delay time before the control returns to standby. Sequence of Operation - GeniSys 7505. Refer to the appliance manufacturer’s wiring diagram for actual specifications. 1. Standby: The burner is idle, waiting for a call for heat. 2. Valve-On Delay: The igniter and motor are on while the control delays turning on the oil solenoid valve for the programmed time. 3.

Section: Burner Control Figure 9. Typical Burner Wiring & Burner Sequence of Operation for R7184P Control. Refer to the appliance manufacturer’s wiring diagram for actual specifications. SK9359 1. STANDBY. The burner is idle, waiting for a call for heat. When a call for heat is initiated, there is a 3-10 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). The fuel valve is opened.

Section: Start the Burner and Set Combustion Oil-Burning Equipment shall be connected to flues having sufficient draft at all times to ENsure safe and proper operation of the burner. Step 4: Recheck smoke level. It should be Zero. Set Combustion with Test Instruments Step 5: Once the combustion has been set, tighten the lower acorn nut and splined nut on the air adjustment assembly. See Figure 10. 1. Allow the burner to run for approximately 5 to 10 minutes. 2.
Section: Perform Regular Maintenance Perform Regular Maintenance Trained Service Technician’s Regular Maintenance Annual Professional Service Required Tampering with or making incorrect adjustments could lead to equipment malfunction and result in asphyxiation, explosion or fire. The following guidelines are provided for routine maintenance. □ Replace the oil supply line filter. The line filter cartridge must be replaced to avoid contamination of the fuel pump and nozzle.
Section: Perform Regular Maintenance Removing Nozzle Line for Service Nozzle Installation (Reference the Replacement Parts Diagram.) Perform the following steps when replacing a nozzle. Correct Nozzle and Flow Rate Required Incorrect nozzles and flow rates could result in impaired combustion, underfiring, over-firing, sooting, puff-back of hot gases, smoke and potential fire or asphyxiation hazards.
