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.

opened. A fl ame should be established within the
15 second lockout time.

4. LOCKOUT. If fl ame 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.

ensure fl ame 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.

7. RECYCLE. If the fl ame is lost while the burner is
fi ring, the control shuts down the burner, enters a 60
second recycle delay, and then repeats the above
ignition sequence. If fl ame is lost three times in a
row, the control locks out to prevent cycling with
repetitious fl ame loss due to poor combustion.

Start the Burner and Set Combustion
Start the Burner and Set Combustion
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 fl ame with the
burner running if the fl ame 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 fi re extinguisher nearby and ready for
use.
