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,
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.
