COMBUSTION SAFETY CONTROL
The AFG type oil burner is equipped with an electronic control (# R7184B1032) including a pre-purge
function and a new more durable drive motor.
PRE-PURGE
When there is a call for heat, the burner's fan will run for 15 seconds before the actual ignition takes place
to vent the combustion chamber and generate a proper draft. This will result in a smoother ignition of the oil
burner.
SAFE OPERATION
If the flame goes out while the burner is running, the CAD cell will detect it; the control will then switch to
the "RECYCLE" mode and cut the fuel supply to the burner for 60 seconds. After this delay, the control
goes back to "IGNITION" mode. If the flame goes out 3 times in a row, the control will switch to the
"LOCKOUT" mode to prevent a continuous cycling of the ignition process, which would cause a premature
sooting of the combustion chamber and smoke pipe. To deactivate the "LOCKOUT" mode, press and hold
the reset button of the control for 30 seconds.
A green diagnostic LED on the control has four states:
-
On = Flame present
-
Off = No flame
-
2 seconds On, 2 seconds Off = "Recycle" mode
-
1/2 second On, 1/2 second Off = "Lockout" mode TEMPORARY SHUT-OFF
By pressing and holding the reset button, the burner will shut-off until the reset button is released. When
the button is released, the control will start over at the beginning of the normal cycle.

BURNER INSTRUCTION MANUAL.
