INSTRUCTIONS FOR DETERMINING THE CAUSE LEADING TO IRREGULARITIES IN THE
OPERATION AND THEIR ELIMINATION
IRREGULARITY
The equipment locks out with the flame
on (red lamp on). The fault is in the flame
control device.
The equipment goes into lock-out spraying
liquid fuel but the flame does not ignite (red

2 The ignition transformer cables are
discharging to ground.
3 The ignition transformer leads are not
properly connected.
4 Ignition transformer is faulty.
5 The electrode faces are not at the right
distance.
6 Electrodes discharge to earth because
they are dirty or their insulation is
cracked: check also the porcelain
insulator terminals.
1 Pump pressure is not regular.
2 Water in the fuel.
3 Too much combustion air.
4 Air passage between flame disk and
diffuser excessively closed.
5 Nozzle worn out or dirty.
1 Thermostats (boiler or room) or
pressure switches are open.
2 Flame sensor short circuit.
3 Absence of line voltage, main switch
open, meter switch tripped or absence
of line voltage.
4 Thermostat line not wired according to

5 Clean or replace.
1 Raise the thermostats settings, or
