4.2. Control, regulating and security devices
The boiler is controlled and regulated by the control unit - see separate service instructions.
Security elements that ensure safe operation of the boiler:
Safety thermo regulator (safety switch) is used to prevent the heating system from overheating.
In production, the safety switch is set to 95°C, i.e. to a higher temperature than the possible
operating temperature of the boiler. The safety thermo regulator is located on the side of the boiler
in the control unit switchboard.
Thermal overload (motor protection) is a part of the fuel feeding device drive that protects it
from burn off, especially in the case when the feed device is blocked. This element also
disconnects the ventilator to prevent fire penetration to the container. During the regular operation,
the temperature of the engine can reach 85°C - such a temperature is not a sign of breakdown.
Turnstile is a device that mechanically separates the fuel in the container from the fuel in the worm
feeder. This technical solution ensures that if the fuel in the worm feeder device starts burning, the
fire cannot expand in the fuel container (especially in the case of long time power cut).
Emergency extinguishing system is another security element that prevents fire from expanding in
the fuel container. If the temperature at the bottom of the fuel container rises over 95°C, a paraffin
plug at the bottom of the container melts and the container is cooled with water from a plastic
reservoir. If the boiler is equipped with a thermostatic valve with pressure tank (optional) and the
temperature at the bottom of the fuel container rises over 95°C, the thermostatic valve opens and
the bottom of the fuel container is filled with water from the water supply system or from the
installed water pressure tank.
Firing flap is placed among the second and third pass in the upper part of the boiler body and it
regulates the temperature of exhausts on output. During the boiler operation, when the temperature
of exhausts rises over 100°C, the firing flap must be closed, i.e. the firing flap adjusting handle on
the side of the boiler must be turned in the forward direction (towards you) and secured by means
of the locking screw with plastic head. When firing (cold chimney) or in cases when the boiler runs
on minimum power over longer periods of time, it is recommended to operate the boiler with the
firing flap partly open to prevent the exhaust temperature from dropping below 80°C. In this case, it
is necessary to turn the firing flap adjusting handle in the rearward direction and secure by means
of the locking screw with plastic head.
