•
Check that there is a constant pressure of 20 mbar for Natural gas (28 – 30 mbar for Butane or 37 mbar for
Propane). If the pressure is insufficient, it is necessary to check the gas supply/pipework and correct any
fault.
•
Shut down boiler.
•
Remove pressure gauge, tighten up carefully test point screw and check for gas soundness.
Setting the central heating output
The central heating output must be set in accordance with the system requirements.
Setting procedure as follows:
•
Push and hold the Mode button for at least 8 sec. The display will switch to service mode, the symbol
n-
will be displayed
•
Set the desired output value from
n1
to
n9
by means of buttons (6)
and (9) according to the following table:

Safety devices
Air flow rate safety device
If an obstruction, even partial, of the flue occurs, the built in safety system of the boiler will turn the boiler OFF.
The boiler will be ready to operate when the fault has been cleared.
In case of power supply failure
The boiler no longer operates. As soon as power is restored, the boiler will be automatically restarted. If the
boiler does not restart, the overheat device may need resetting.
Overheat safety
In the event of overheating, the overheat safety device causes safety shut-
down of the boiler. The digital display will show error code F1. To reset, let the
boiler cool down, press the reset button on the safety devices (a) and (c), see
diagram 22 and reset boiler controls by means of the reset button (8).
Note:
wire connections to overheat thermostat are mains voltage.
Important notice
A central heating system cannot operate satisfactorily unless it is properly
filled with water and unless the air initially contained in the pipework system
has been properly bled off. If these conditions are not satisfied, air noise will
occur within the system and the boiler may fail to operate.
To reset the boiler (other than for overheating) use the reset button on the
fascia, see diagram 15.
The
Protherm 80EC
boiler has a built-in frost protection device that protects the boiler during freezing condi-
tions. This device works irrespective of any room thermostat setting and only protects the boiler.
Should the temperature within the central heating circuit of the boiler fall below 10 °C, the pump will switch on
providing the electrical supply has been left connected. If the temperature falls below 8 °C, then the burner will
operate until the water temperature increases to 25 °C. Should the electrical supply have been disconnected
and the boiler/system has frozen, the boiler will not start up until the boiler/system has been cleared.
