Instruction Manual – Model CF2300A Oil Burner

Sequence of operation — typical

NOTE: The following sequence is based on using a type B fuel unit, with pump-mounted by-pass valve. The by-pass valve operation is reversed for a type H fuel unit. That is, the by- pass valve is powered at low fire instead of being powered at high fire.

1.On call for heat from the appliance operating controls (and the circuit from T to T of the R8184 closed), power is applied to the R8184 black wire (BK).

2.The R8184 applies 120 volts to the orange wire (OR), acti- vating 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 inlets.

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, oil valves (S1 and S3) are activated, allowing oil to flow to the nozzle.

4.With the low-fire hold switch (LFHS) in the “ IN” position, the burner will remain at low fire. With no power applied to the by-pass valve (S2), oil by-passes internally in the fuel unit, reducing the pressure sent to the oil nozzle.

5.When the low-fire hold switch is moved to the “ OUT” position, the damper motor (DM) will be activated. This will begin opening the air damper.

6.When the damper motor end switch is tripped, oil valve (S2) is activated, stopping by-pass flow inside the fuel unit and providing full pressure (300 psig) at the oil nozzle. The burner is now at high fire. The damper motor end switch is set to operate before the damper has reached full open to assure a smooth transition to high fire.

7.If a high/low-fire control is installed at H/L, this control will cycle the firing rate automatically during an operat- ing cycle.

8.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 con- trol 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, al- lowing the burner to operate in normal sequence.

Troubleshoot the reason for flame sense failure.

9.When the call for heat signal terminates (at the black wire of the R8184), the R8184 terminates power to all circuits, closing the oil valves 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 and external by-pass loop — from Return port to pump Inlet — have been installed for one- pipe oil systems. By-pass plug is installed for two-pipe oil systems.

Fuel connection to nozzle line assembly is secure.

Dimension Z has been set per this instruction manual.

Fuel supply line is correctly installed, the oil tank is sufficiently filled, and shutoff 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.
