information on the safety Devices :
at a boiler temperature of 85°c, the boiler switches to overheating mode or to modulation mode. This is an attempt to “slow down” combustion,
in order to prevent a further rise in temperature, without stopping combustion.
When the boiler temperature reaches 90°c, the smoke fan is deactivated in order to stop the combustion air and thus stifle combustion.
In ThIs sITuaTIon, IT Is ImPorTanT To keeP all boIler doors closed because There Is a rIsk of exPlosIon!
auTomaTIc Thermal dIscharge valve d.s.a.
The automatic thermal discharge discharge valve d.s.a. is triggered at about 93°c.
The safety cooling exchanger is crossed by a flow of cold water that protects the boiler from dangerous overheating temperatures above
100°c.
Thermal safeTy ThermosTaT
When a temperature of 95°c has been reached, the thermal safety thermostat is triggered.
It interrupts the supply to the smoke fan in order to stop the combustion air and thus stifle combustion. only after the boiler has cooled down
(to a temperature below 60°c) can the thermal safety thermostat be reset.
aDDinG fuel
fill the loading chamber only when the filling space is mostly empty and there is only a layer of embers.
The fuel level in the loading chamber is controlled by the ignition door to prevent any smoke from escaping if there is too much residual fuel.
If There Is Too much unburned fuel In The combusTIon chamber, There Is a rIsk of exPlosIon When The loadIng
door Is oPened.
When the external panel is opened to access the loading door, the fan automatically increases its suction speed to prevent any smoke from
escaping.
at this point, slowly open the loading door.
To do this, list the door handle to the first latch position and wait a few seconds in this position so that any exhaust gases can escape through
the door.
Then open the door completely and add fuel in such a way that the logs fit tidily next to one another, to prevent the flames from spreading
too quickly in the gaps between the logs.
close the loading door and leave the ignition door slightly open until the smoke temperature has reached 220°c.
When refilling, it is necessary to take into account the exhaust gas temperature. If the smoke temperature falls below 100°c, the boiler will
shut down.
In this case, it is necessary to repeat the steps described in the chapter “heaTIng (normal oPeraTIon)”.
