Instruction Manual – Model CF1400 Oil Burner

Start the burner

Do not proceed unless all prior steps in this manual have been completed. Failure to comply could result in severe personal injury, death or substantial property damage.

Do not attempt to start the burner when excess oil has accumulated, when 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 should be extinguished during start-up, venting or adjustment. Allow the unit to cool off and all vapors to dissipate before attempting another start. Failure to comply with these guidelines could cause an explosion or fire, resulting in severe personal injury, death or substantial property damage.

❏Starting the burner and venting air

1.Verify that the air adjusting plate (Figure 12, item m) has been set to the initial air position as described on page 12 under Initial air settings.

2.Open the oil shut-off valves in the oil supply (and return) line(s) to the burner.

3.Set the thermostat (or operating control) to call for heat.

4.Close the line switch to the burner. The burner motor should start immediately.

5.If the burner motor does not start, reset the motor overload switch (if so equipped) and press the reset switch of the burner primary control.

6.Vent the fuel unit as soon as the burner motor starts rotating. To vent —

❏Attach a clear plastic tube to the air bleed valve (Figure 8a, 8b, 9a or 9b as applies, item p).

❏Place the end of the tube in a container to catch the oil. Then loosen the fuel unit air vent valve.

❏Tighten the air vent valve after all air has been purged.

❏IF burner stops during venting —

•The burner primary control will lockout if flame is not established within its time limit. This is typically 15 seconds for R8184 primary controls, but may be less for other flame supervisory controls.

•The burner may lockout several times during the period needed to purge all the air. Reset the primary control each time in order to continue purging.

•If the burner is equipped with an R8184 primary, you will need to wait about 2 minutes after each lockout to allow time for the reset switch to cool.

•Squeeze off the air bleed tubing or close the air vent valve when the pump stops running to prevent air from flowing back into the oil line.

If the fuel unit air vent valve is completely open, assuring no flow of oil to the burner oil nozzle, you can temporarily jumper the F-Fterminals of an R8184 primary during the purge period to allow enough time for all air to purge. Never leave the burner unattended when doing this. Remove the jumper when purging is completed. This procedure should only be used by a qualified burner technician, experienced in burner operation and control. Improper application of this method can cause combustion chamber explosion, fire hazard or fuel leakage, resulting in severe personal injury, death or substantial property damage.

❏IF burner stops after flame established —

•Additional venting is probably required. Repeat the air venting procedure.

7.Once flame is steady, proceed to Set air adjusing plate.
