Oil supply connects to one of the fuel unit Inlet ports. Two-pipe systems – See Figure 10 for the fuel flow paths for high-fire and low-fire operation. The low-fire by-pass regulation is done internally for type B fuel units. Oil supply connects to one of the fuel unit Inlet ports. Oil return connects to the fuel unit Return port. Do NOT install valves in the return line.

Table 3 – Fuel Unit Gearset Capacities Model Fuel Unit Model Number Gearset Capacity (gph) CF1400 B2TA-8245 23 CF2300 B2TA-8852 39 The fuel unit nozzle port pressure is factory set at 300 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. Wire the Burner Electrical Shock Hazard Electrical shock can cause severe personalinjury or death. • Disconnect electrical power before installing or servicing the burner. • Provide ground wiring to the burner, metal control enclosures and accessories. (This may also be required to aid proper control system operation) • Perform all wiring in compliance with the National Electric Code ANSI/NFPA 70 (Canada CSA C22.1). Install the burner and all wiring in accordance with the National Electrical Code and all applicable local codes or requirements. Wire the burner in compliance with all instructions provided by the appliance manufacturer. Verify operation of all controls in accordance with the appliance manufacturer’s guidelines. See Figure 13 (7505P) or 14 (7184B) for a typical wiring diagram (for reference purposes only). Incorrect Wiring Will Result in Improper Control Operation • GeniSys 7505 Control wiring label colors maynot match the wire colors of the burner or other manufacturers’ controls. • The GeniSys Control should be wired according tothe appliance manufacturer’s instructions. Fire or Explosion Hazard Can cause severe injury, death, or property damage. • The control can malfunction if it gets wet, leading toaccumulation of explosive vapors. • Never install where water can flood, drip or condense on the control. • Never use a control that has been wet - replace it. Typical Burner Sequence of Operation - 7505 Control 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. Trial For Ignition: The oil solenoid valve is energized. Aflame should be established within the factory set trial for ignition time (lockout time). 4. Lockout: The control has shut down for one of the following safety reasons: a. The trial for ignition (lockout) time expired without flame being established. b. The cad cell detected flame at the end of the Valve On Delay state. To reset the control from lockout click the button 1-second. NOTE: A recurrence of the above failure modes or a failed welded relay check could cause the control to enter a Hard Lockout state that must be reset only by a qualified service technician. To reset from Hard Lockout, hold the reset button for 15 seconds until the yellow light turns on. 5. Ignition Carryover: Once flame is established, the igniter remains on for 10 additional seconds to ensure flame stability. 11CF1400/CF2300 Burner Manual Section: Wire the Burner 6. Run: With a flame established and the control continuing to detect a flame, the burner will operate in the RUN Mode until the load demand is satisfied or a limit opens. a. If terminals RC1 and RC2 are jumpered, the burner operates in the Low-High-Off Mode. The burner starts at Low, goes to High after the flame stabilization period. Flame is extinguished when the load is satisfied or a limit opens, and the burner is sent to motor off delay. b. If a high/low control has been wired between terminals RC1 and RC2 the burner starts at Low and is released to go High after the flame stabilization period. It can repeatedly cycle between low and high as necessary to meet load demand until the load is satisfied or a limit opens. The burner is then sent to Motor-off Delay. 7. Recycle: If the flame is lost while the burner is firing, the control shuts down the burner, enters ...
