Instruction Manual – Model CF500/CF800 Oil Burner

Wire the burner — R7184

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 9a for a typical wiring diagram, with R7184 oil primary, for reference purposes only.

Sequence of operation — typical

1.Standby — The burner is idle, waiting for a call for heat. When a call for heat is initiated, there is a 2- to 6-second delay while the control performs a safe start check.

2.Valve-on delay — As applicable, the ignition and motor are turned on for a 15-second prepurge.

3.Trial for ignition (TFI) — The fuel valve is opened, as applicable. A flame should be established within the 15- second lockout time (30-second lockout time is avail- able).

4.Lockout — If flame is not sensed by the end of the TFI, the control shuts down on safety lockout and must be manually reset. If the control locks out three times in a row, the control enters restricted lockout. Call a qualified service technician.

5.Ignition carryover — Once flame is established, the ignition remains on for 10 seconds to ensure flame stability. It then turns off.

6.Run — The burner runs until the call for heat is satisfied. The burner is then sent to burner motor-off delay, as applicable, or it is shut down and sent to standby.

7.Recycle — If the flame is lost while the burner is firing, the control shuts down the burner, enters a 60-second recycle delay, and then repeats the ignition steps outlined above. If the flame is lost three times in a row, the control locks out to prevent continuous cycling with repetitious flame loss caused by poor combustion.

8.Burner motor-off delay — If applicable, the fuel valve is closed and the burner motor is kept on for the selected postpurge time before the control returns the burner to standby.

Do not by-pass any safety control. By-passing a safety control could result in severe personal injury, death or substantial property damage.

Electrical shock hazard - can cause injury or death. Disconnect power before installing or servicing. Provide ground wiring to the burner in accordance with the National Electrical Code.
