POSSIBLE CAUSE
1. Photo-resistance circuit is broken or the Pho-
to-resistance is dirty with smoke residue
2. Dirty fuel filter
3. Flame Control device Circuit is broken
4. Flame disk or tube (Fig. 12, 13, 14) dirty
1. The electrical system is not compatible
2. Ignition Transformer (M Fig. 6) disconnected or
broken
3. Ignition Transformer wires short circuit to
ground
4. The electrodes are not at the proper distance
5. The electrodes short circuit to ground because
they are dirty or the insulation is damaged
1. Photo-electric cell sees a strong source of light
2. The power supply is missing a phase to the
motor
3. Fuel is not arriving to the pump
4. No fuel in the tank
5. Nozzle clogged
1. The control device (Thermostat or Timer) is on
2. Short circuit in Photo-resistance (T Fig. 6)
3. Power loss due to: disconnected switch (4) or
disconnected main switch due to power loss in
the line
4. The installation of the control device (Thermo-
stat or Timer) is not correct
5. Break inside the flame control device
6. Fuse inside the burner bonnet
1. Low pulverisation pressure
2. Insufficient combustible air
3. Nozzle clogged because it is dirty or old
4. Water in the fuel. Poor quality fuel
5. The tank is running out of fuel
SOLUTION
1. Clean or replace the Photo-resistance
2. Remove filter and clean it

3. Replace it
4. Reposition them at the correct distance (see
Fig. 14)
5. Clean them or, if necessary replace them
1. Place the machine so that the light source
does not directly face the front deflector
2. Control the electric system
3. Control the fuel supply lines (D Fig. 3)
4. Resupply the fuel tank
5. Dismantle and clean or replace it
1. Raise the value or control the Timer settings
2. Replace it
3. Turn off the electric system and then turn off
the switches or wait for the power supply to
return
4. Control the installation following the descrip-
tion in the "CONNECTING THE CONTROL
DEVICE" paragraph
5. Replace it
6. Open the burner coffer (F Fig. 5) and replace
it
1. Reestablish the correct value
2. Increase the combustible air
3. Clean or replace the nozzle
4. Drain the fuel from the appropriate drain plug
(M Fig. 4)
5. Resupply the tank
