13. SAFETIES
These are the safeties included in the boiler:
Cause for safety
activation Safety
component of
the boiler Boiler restart
No flame Ionization
electrode Manual reset
Fan failure/air
passage obstruction Air pressure
switch Manual reset
Overheating Safety
overheating
thermostat
> 90ºC+- hysteresis: the regulation stops the boiler.
> 95ºC: boiler lockout, error on the display. Manual reset.
> 100ºC: fan at the maximum power to cool down the boiler.
> around 103ºC: lockout, other error on the display, manual reset.
No gas Minimum gas
pressure switch Automatic reset
Low water flow
through the boiler Boiler control unit Safety 1: if the DeltaT in the boiler is higher than the maximum Delta
T, the power drops by 20%.
Safety 2:
if it overcomes “the maximum Delta T” + 8ºC, the boiler
operates at the minimum power.
Safety 3: if it overcomes a higher value, the boiler stops and an error
message appears on the display E 154/434 or E 154/433.
Lack of water
pressure in the circuit Pressure sensor The boiler stops for safety if pressure in the circuit is around 0,8 bar.
14. BOILERS IDENTIFICATION LABEL
The identification label of each boiler is placed:
a) In the front of the boiler, attached to the
higher water collector of the boiler heat
exchanger.
In order to visualize it, you have to lift up the
top casing of the boiler and remove the front
