Section: Pre-installation Checklist Owner’s Responsibility: Follow These Instructions Exactly Failure to follow these instructions, misuse, or incorrect adjustment of the burner could lead to equipment malfunction and result in asphyxiation, explosion or fire. Contact a professional, qualified service agency for the installation, adjustment and service of your oil burning system. Thereafter, have your equipment adjusted and inspected at least annually to ensure reliable operation.
Section: Pre-installation Checklist the fuel unit (oil pump) on the burner. Refer to fuel unit literature in the literature envelope in the burner carton to verify allowable suction pressure. The fuel unit nozzle port pressure is factory set at 140 psig. Some original equipment manufacturer burner applications may call for a lower pressure to obtain a required firing rate. Do not change this pressure unless directed to do so by the appliance manufacturer.
Section: Pre-installation Checklist Inspect Chimney or Direct Vent System 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.
Section: Mount the Burner Verify air tube Stray Light The information in this section may be disregarded if the air tube is supplied by the appliance manufacturer. Protect Against Stray Light Lockout Failure to follow these instructions could cause loss of burner operation resulting in no heat, an unplanned process interruption, work stoppage and the potential for frozen plumbing or other cold weather property damage. Two tube arrangements are available – ○ CF500 1.75 to 5.50 GPH ○ CF800 Tube A — 3.
Section: Mount the Burner Mount flange(s) on air tube Install nozzle This section does not apply to burners with welded flanges. Install the oil nozzle in the nozzle adapter. Use a 3/4” open-end wrench to steady the nozzle adapter and a 5/8” open-end wrench to turn the nozzle. Tighten securely but do not over-tighten. 1. Do not install air tube on burner. 2. For non-pressure firing flange, refer to Figure 4: Install gasket (item a) and flange (item d). Ignore the next paragraph. 3.
Section: Mount the Burner Figure 6 - Nozzle line assembly in burner Z-Dimension 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. CF800 1-3/4” CF500 1-9/16” Fuel unit by-pass plug Z y The burner is shipped without the by-pass plug installed. CF500/800 (with CF140KZ Air Tube) y Intall the by-pass plug in two-pipe oil supply systems ONLY.
Section: Wire the Burner ○ gearset flow capacity (Table 3) for two-pipe systems. Size the filter for the firing rate for onepipe systems. Locate the filter immediately adjacent to the burner fuel unit. Install two high-quality shut-off valves in accessible locations on the oil supply line. Locate one valve close to the tank. Locate the other valve close to the burner, upstream of the fuel filter. Table 3.
Section: Wire the Burner Figure 10.
Section: Wire the Burner Explosion, Fire, Scald, and Burn 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. y Follow the appliance manufacturer’s wiring diagrams and note all required safety controls. y Typical safety controls include high temperature or pressure limits, low water cutoffs, pressure relief valves and blocked flue sensing switches.

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.
Section: Prepare the Burner for Start-up Figure 12. - Typical wiring (R7184) Professional Installation and Service Required Incorrect installation and mishandling of start-up could lead to equipment malfunction and result in asphyxiation, explosion or fire. y This burner must be installed and prepared for startup by a qualified service technician who is trained and experienced in commercial oil burner system installation and operation. y Do not attempt to start the burner unless you are fully qualified.
Section: Prepare the Burner for Start-up □ Fuel connection to nozzle line assembly is secure. Initial air settings (Table 8) □ Dimension Z has been set per the ‘Set Z ○ Dimension’ instructions detailed earlier in this manual. The acorn nut (Figure 7, item C) should never be loosened once the Z dimension is initially set. □ Fuel supply line is correctly installed, the oil tank is sufficiently filled, and shut-off valves are open.
Section: Start the Burner Start the Burner Explosion and Fire Hazard Failure to follow these instructions could lead to equipment malfunction and result in heavy smoke emission, soot-up, hot gas puff-back, fire and asphyxiation hazards. - Priming the Pump For 7505 Control: ○ ○ ○ ○ y Do not attempt to start the burner when excess oil has accumulated in the appliance, the appliance is full of vapor, or when the combustion chamber is very hot.
Section: Start the Burner Cad Cell Resistance Measurement ○ ○ If the Beckett 7505 control is equipped with the GeniSys Display Module, part 52067U, the cad cell resistance can be selected and read on the LCD screen. Also, the GeniSys Contractor Tool, part 52082U, can be used for this purpose. If these are not available, the cad cell leads can be unplugged from the control and the resistance measured with a meter in the conventional way. Conduct these tests with flame present.
Section: Maintenance and Service Maintenance and Service Annual Professional Service Required Tampering with or making incorrect adjustments could lead to equipment malfunction and result in asphyxiation, explosion or fire. y DO NOT TAMPER WITH THE UNIT OR CONTROLS - CALL YOUR SERVICE PERSONNEL. y To ensure continued reliable operation, a qualified service technician must service this burner annually. y More frequent service intervals may be required in dusty or adverse environments.
