5.6 IMPROPER OPERATING PROCEDURES
Before making any direct control on the unit, make sure that:
- There is a full electricity supply.
- There is a full gas supply
- The feeling pressure to the burner is within the tolerances given.
Only after all the above checks have been successfully carried out, a specific trouble
shooting could commence.
Before removing the casing to access to the electrical control box CUT OFF
POWER SUPPLY to the unit by means the bi- polar switch positioned on the upper
part of the unit, or remove the electrical plug.
CASE 1:
THE UNIT LOCKS OUT DURING THE FIRST PHASE OF START UP
A) The gas flow is not enough. Verify that all manual valves and gas taps are open. In
case the unit has not been used for a long time, it could be due to some air in the
pipes. Reset it 3, 4 times and the unit will restart.
B) The plug polarity is not correct: verify it. In case you use an external plug, remove it,
turn it 180° and plug in it.
C) The ignition electrode is broken or improperly installed: replace it or reposition it
properly.
D) The flame sensor is broken or improperly installed: replace it or reposition it
properly.
)
For a correct ignition the distance between the two ignition electrodes should be 3-5
mm.
E) One of the ignition electrode or the wire cable are in touch with the shell or any other
metallic part: verify it removing the shell.
F) Ignition components failure: replace it
CASE 2:
THE UNIT LOCKS OUT DURING OPERATION
A) The safety thermostat stopped the gas valve to avoid overheating caused by:
•
Obstruction on the upper heated air outlet. Remove the obstruction
•
Fan failure (models 42, 51 and 52); replace it.
B) Failure to the ventilation thermostat (models 42, 51 and 52). The ventilation
thermostat does not permit the fan to work properly; replace it.
C) Failure to the gas valve; replace the coil or the gas valve.
)
In case of gas valve replacement it is necessary, as requested by local norms, seal
the nozzle support with a conforming sealing to the norms (ideal for gas seal).
D) Bad connection of safety thermostat; check cables and connections.
