With the bumer in the start position and the appliance thermostats enabled, power is delivered to the
resistances (G) of the preheater and heating cartridges for the pumps and the fuel supply line to the head (O).
When the preheater thermostat reaches the set value, (usually a minimum of about 90°C is necessary to
guarantee a good level of circulation) the pump start-up is enabled (set point on out 1, if using the GEFRAN
200 thermoregulating device). If the preheating system of the tank is also equipped for a fluid exchanger (hot
water, steam, diathermic oil) the thermostat may enable a contact in the terminal block for any stop-start of
the fluid electrovalve. This is not a standard solution as the heated fluid is normally always connected. The
pump starts to send oil (the head has already been heated by its cartridge (O) and therefore has no residue
of cold dense oil) which flows from the tank to the head and then to the return line of the ring. When the head
thermostat reaches the set value (usually about 70-30°C the cycle starts properly and the control programmer
enables start-up. The servomotor sets itself at minimum (see chapter on regulation) acting on the air and fùel
via the pressure regulator on the return.
The electromagnet (A) opens the nozzle (Q) in the followmg condition :
- sparks from the ignition electrodes are generated by the transformer also governed by the burner
control device. If the cell fails to detect the flame the burner shuts down (with the cyclic control programmer
cutting in). Once ignition has taken place and after the flame stabilisation period, the system starts
operating in modulating mode.
- Before start-up make sure that the pump and delivery pipes are completely filled with hot fuel oil; the
absence of fuel oil can cause pump seizure.
- If there is a block, a specific waring light on the programmer and on the burner front control board
lights up and this signal is usually sent to the main control board of the equipment using the burner,
setting off a buzzer and warning light. - A few blocks are normal on first starting up (up to about 4); to release press the button on the
programmer (also found on the front of the bumer control board) for repeating the start cycle. Should
they continue to occur seek the help of a specialised technician.
N.B. The position of the programmer at the time of the block is memorised to supply an indication of the
cause of this block.
In case of burner lockout, it is possible to read which cause originated it. Proceed as follows: with the burner in lockout
mode (red LED switched on) keep pressed the lockout button for more than 3 sec. then release it. The red LED will blink
according to the following error code list:
