Start the Burner and Set Combustion

Figure 4b. – Typical Burner Sequence of Op- eration

1.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. The ignition and motor are turned on for a 15 second valve-on delay.

3.TRIAL FOR IGNITION (TFI). The fuel valve is opened. A flame should be established within the 15 second lockout time.

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.

5.IGNITION CARRYOVER. Once flame is estab- lished, the ignition remains on for 10 seconds to ensure flame stability before turning off. If the con- trol is wired for intermittent duty ignition, the ignition unit stays on the entire time the motor is running.

6.RUN. The burner runs until the call for heat is sat- isfied. The burner is then sent to burner motor off delay, if 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 above ignition sequence. If flame is lost three times in a row, the control locks out to prevent cycling with repetitious flame loss due to poor combustion.

8.BURNER MOTOR-OFF DELAY. The fuel valve is closed and the burner motor is kept on for the se- lected motor-off delay time before the control re- turns the burner to standby.

Start the Burner and Set Combustion

!WARNING Explosion and Fire Hazard

Failure to follow these instructions could lead to equipment malfunc- tion and result in heavy smoke emission, soot-up, hot gas puff- back, fire and asphyxiation hazards.

•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.

•Do not attempt to re-establish flame with the burner running if the flame becomes extinguished during start-up, venting, or adjustment.

•Vapor-Filled Appliance: Allow the unit to cool off and all vapors to dissipate before attempting another start.

•Oil-Flooded Appliance: Shut off the electrical power and the oil supply to the burner and then clear all accumulated oil before continuing.

•If the condition still appears unsafe, contact the Fire Department. Carefully follow their directions.

•Keep a fire extinguisher nearby and ready for use.

•Start-up and Initial Settings

1.Open the shutoff valves in the oil supply line to the burner.

2.Referencing Figure 5a or 5b, verify and/or set the Head/Air Adjustment Pointer to the value speci- fied by the Appliance Manufacturer. If the Appli- ance Manufacturer’s values are not available, refer to Table 3a or 3b. (This is an initial air set- ting for the pump bleeding procedure only.) Calibrated test instruments must be used for the final head/air adjustment.

3.Adjust the thermostat or temperature controller to call for heat. (Note: return controller(s) to the original settings upon completion of burner instal- lation or service.)

4.Close the line voltage switch to start the burner. If the burner does not start within the 3 to 10 second safety start check timing, you may have to reset the safety switch on the burner primary control.

5.Bleed the air from the fuel pump as soon as the burner motor begins rotating.

6.Prepare for combustion tests by drilling a 1/4” sampling hole in the flue pipe between the appli- ance and the barometric draft regulator. Seal this hole when testing is complete. (See appliance manufacturer’s instructions for location.)
