If the temperature of the heating water reaches 95 to 100
°C the emergency thermostat responds by shutting
the boiler off separately from the programmer. The programmer then displays signal overheating.
The emergency thermostat can be switched back on by unscrewing the black emergency thermostat cover
and pressing the colour button only when the temperature drops below the set value by approx.
20 °C. The
black cover then needs to be put back into its original position.
To avoid unwanted response of the emergency thermostat it is recommended the heating water on the exit is
set to 80
°C.
In case of repeated response of the emergency thermostat the boiler must be shut down and the cause of the
repeated overheating of the boiler must be investigated.
7.4. Shutting the boiler down
The boiler
is shut down automatically by the programmer (see separate user’s instructions for operating the
programmer). There is no need for an intervention by the user.
IMPORTANT:
•
It is not safe to use this appliance by people (including children) with physical, sensory or
mental disability or by people with lack of experience and knowledge.
•
It is unacceptable to leave children unattended near the boiler whilst in operation.
•
The boiler must be decommissioned if there is a danger of formation and presence of flammable
gasses in the boiler room or during works (such as gluing of flooring, using flammable paint,
etc.) with interim danger of fire or explosion.
•
Special attention must be paid to the lower part of the fuel store where the screw feeder is
located. The free (rotating) end of the screw feeder must be covered by the fuel at all times and
secured so it cannot be touched by hand. Rotating screw feeder can cause serious injuries.
•
It is forbidden to use flammable liquids to ignite the boiler.
•
If there is need to observe the flame during the boiler operation, this must be done by opening
the door. If it is necessary to open the boiler door during the boiler operation (i.e.: to remove ash
from the ash drawer) there is increased risk of sparks or smoke entering the boiler room. In this
instance it is necessary to immediately close the boiler door. To open the door during the boiler
operation the user must take great care and follow these steps: open the door slightly, wait until
the flue gases disperse from the combustion chamber and then open the door fully.
•
The fuel store lid must be carefully closed during the boiler operation.
•
The fuel store is filled with fuel up to the height of maximum approx. 30 mm below the lower
edge of the store to ensure the lid can be closed securely.
•
It is forbidden to overheat the boiler during its operation.
•
Do not place flammable objects on the boiler and closer than the specified safe distance (see
chapter 5.2.)
•
When removing the ash from the boiler no flammable materials must be closer than 1500 mm
from the boiler. The ash must be placed into a non-flammable container with lid.
•
If the boiler is operated at temperatures lower than 60
°C condensation forms on the steel boiler
body. This is called low-temperature corrosion which shortens the life span of the boiler. The
boiler should therefore be operated at temperatures higher than 60
°C.
•
After the end of the heating season the boiler as well as the flue pipe must be thoroughly
cleaned. The boiler room must be kept clean and dry.
•
It is forbidden to interfere with the construction and electrical installation of the boiler.
•
It is forbidden to use the burner without its housing.
•
The boiler is operated with a fan.
•
The boiler is operated with negative pressure at the flue gases outlet.
•
The boiler operates in conditions without condensation.
•
The burner must not be used as a separate appliance.
