General safety devices
Air flow rate safety device
If an obstruction, even partial, of the flue occurs, for
any reason whatsoever, the built in safety system of the
boiler will turn the boiler OFF and the fan will continue
to run.
The boiler will be ready to operate when the fault has
been cleared.
Overheat safety
In case of boiler overheating, the overheat thermostat
will turn the boiler off. The thermostat, located on the
heat exchanger flow pipe, will need to be manually re-
set.
In case of power supply failure
The boiler no longer operates.
As soon as power supply is restored, the boiler will be
automatically restarted.
Frost protection
The ISOFAST has a built in frost protection device that
protects the boiler from freezing. If the boiler is to be
left and there is a risk of frost, ensure that the gas and
electrical supplies are left connected. The frost protec-
tion device will light the boiler when the temperature
of the boiler water falls below 6
°
C. When the tempera-
ture reaches 16
°
C, the boiler stops.
Note : This device works irrespective of any room ther-
mostat setting and will protect the complete heating
system.
