2. The R8184 applies 120 volts to the orange wire (OR), activating the burner motor (M1) and the ignition transformer (TR). The oil pump is operated by the burner motor, so oil pressure is delivered to the oil valve inlet. 3. Power is applied to the oil valve circuit. If optional timer, (TM), is installed, oil flow will be delayed for the timer duration, thus providing a prepurge period. When the timer times out, the oil valve(s) (S1, and S2 if supplied) is activated, allowing oil to flow to the nozzle. 4. At the start of the cycle, the R8184 begins checking for flame signal between F and F. Flame must be established within 15 seconds of initiation. If no flame is sensed after 15 seconds, the R8184 will terminate all power to the blower and oil circuits, shutting the burner down. The control will electrically lock out. • To reset the control after lockout, wait 2 to 3 minutes after lockout to give the internal switch time to cool. Then push the reset button on the primary control, allowing the burner to operate in normal sequence. • Troubleshoot the reason for flame sense failure. 5. When the call for heat signal terminates (at the black wire of the R8184), the R8184 terminates power to all circuits, closing the oil valve and stopping the burner motor. Prepare the burner for start-up Start-up checklist – Verify the following before attempting to start burner. . Combustion air supply and venting have been inspected and verified to be free of obstructions and installed in accordance with all applicable codes. . Oil nozzle has been selected correctly and securely installed in the nozzle adapter. . Fuel unit by-pass plug has not been installed for one-pipe oil system. By-pass plug has been installed for two-pipe oil system. o Fuel connection to nozzle line assembly is secure. o Dimension Z has been set per this instruction manual. . Fuel supply line is correctly installed, the oil tank is sufficiently filled, and shut-off valves are open. . Burner is securely mounted in appliance, with pressure firing plate and gasket installed for pressurized chamber application. . Appliance has been filled with water (boilers) and controls have been operationally checked. . Burner has been installed in accordance with appliance manufacturer’s instructions (when available). . Also refer to appliance manufacturer’s instructions (when available) for start-up procedures. Form 6104 BCF14N-R0299 Instruction Manual – Model CF1400 Oil Burner Prepare the burner for start-up- continued o Z dimension • Should be set per these instructions (see page 7). The top acorn nut (Figure 11, item d) should never be loosened once the Z dimension is initially set. o Adjusting plate assembly (Figure 11) • Make sure spline nut (item b) and bottom acorn nut (item c) are loose. o Initial head position (Figure 11) • The indicator plate assembly (item e) markings correspond to head position settings. • Slide the secondary adjusting plate (item f) toward the rear of the burner until the number on the indicator plate corresponds to the initial head setting given in Table 4 for the desired firing rate. • Figure 11 shows a typical example, with a head setting of 5. • When the head position has been set, tighten the bottom acorn nut (item c) and the spline nut (item b). o Initial air settings (Figure 12) • Loosen the screw holding the air adjusting plate (item m). Set the air to the desired rate. (The numbers on this plate correspond to the approximate firing rate settings given in Table 5.) • Rotate the air adjusting plate until the lower edge of the pointer is opposite the number from Table 5 corresponding to the desired firing rate. • This initial setting should be adequate for starting the burner. Once the burner is in operation, the air setting will be adjusted for best performance as discussed later in this manual. • Follow the procedures given later in this manual for fine- tuning the air settings.
