7.2. Boiler operation
After fuel flame-up the boiler switches (see separate control unit instruction manual) to automatic operation,
which includes the fan, as well as cycling of the fuel screw feeder. The control unit display visualizes the
basic data regarding the boiler operation.
The boiler operation is automatic until the desired water temperature is reached. As soon as the required
water temperature is reached, the boiler automatically switches to the "attenuation" mode where it remains
until the temperature drops below the medium heating setpoint.
During a power outage (400 V, 50 Hz) the boiler control unit remembers its status and restores to this when
the power returns.
If the heating water temperature exceeds 95 °C, the emergency thermostat will respond to shut down the
boiler irrespective of the control unit. When you turn off the emergency thermostat the control unit indicates
overheating.
The emergency thermostat can be switched on only when the temperature falls below the set value by about
20 °C. This is done by unscrewing the black cap on the emergency thermostat and pushing the colour
button. The black cap must subsequently be restored to its place.
To prevent unwanted switching of the safety thermostat due to the thermal inertia of the boiler, it is
recommended to operate the boiler at outlet heating water temperatures up to 80 °C.
In case of repeated switching off of the boiler by the emergency thermostat, the boiler must be shut down
and the user must determine the cause of the repeated overheating.
7.3. Boiler shutdown
Before the boiler is shut down, it is necessary to use manual control to push the hot fuel from the feed area
of the boiler and burner into the ash tray drawer. This is not necessary for short repairs when an operator is
present.
IMPORTANT ADVICE:
•
This appliance is not intended for use by persons (including children) whose physical, sensory
or mental disability or lack of experience and knowledge prevents them from using the
appliance safely.
•
It is unacceptable to leave children unattended near the boiler when it is in operation.
•
If there is a danger of combustible vapours or gases building-up in the boiler room or there is
work involving a temporary fire or danger of explosion (gluing of floorings, painting with
combustible paints, etc.) taking place in the boiler room, the boiler must be shut down before
beginning any work.
•
When transporting fuel into the combustion chamber before firing, it is necessary to check the
amount of fuel in the burner visually, not by inserting hands into the burner. There is a risk of
injury from the rotating screw shaft.
•
It is forbidden to fire the boiler using flammable liquids.
•
Observation of the flame during boiler operation is possible by opening the door. If it is
necessary to open the door during boiler operation (e.g. for removal of ash from the ash tray
drawer), it should be noted there is an increased danger of sparks and smoke development in
the boiler room. If this happens the door must be closed immediately. The door must only be
opened with caution during boiler operation, i.e. slightly ajar at first then wait until the exhaust
gases from the combustion chamber are extracted and only then open it completely.
•
During operation it is forbidden to overheat the boiler in any manner.
•
It is not allowed to place any articles made of flammable materials on the boiler or within a
distance smaller than the safe distance from it (see chap. 5.2.).
