16.0 Precautionary Measures.
The KSM-Stoker meets with all current EU regulations regarding Small & Medium Bio fuel Boilers.
16.1 Fire Protection, thermal.
The KSM-Stoker is provided with a thermal valve with a sensor and also a pressure tank with a non-
return valve, to avoid losing the water in the tank even if its water supply should fail.
The sensor registers if the screw tube runs too hot i.e. up to more than 95
o
C and should this occur, the
thermal valve will turn on the water in the pressure tank and the water will extinguish the fire and ember.
Once this has been done, the thermal valve will cool down and the water is automatically turned off
again, in order to avoid a flooding.
If the valve is overheated please notice if it closes tightly because it otherwise will leak water.
16.2 Personal Protection.
The KSM-Stoker is fitted with a safety switch on the silo lid; this switch will cut off the electric power
to the stoker if the lid is opened. This is to protect you against any damage while handling screw or
stirring device.
16.3 Electric Protection Fuses.
The KSM-Stoker control is furnished with overload protection on each motor which is triggered if the
screw motor should be exposed to overcharge. Furthermore, fuses are mounted inside the control as a
protection of the control itself and its other components.
16.4 Maximum Heat Thermostat.
The KSM-Stoker is provided with a sensor for interruption of the control in case the boiler has been
heated to more than 95
o
C. If this sensor has been activated, it must be manually re-set by means of the
small pressure button. The maximum heat thermostat is mounted in the upper left corner of the Control
Panel.
16.5 Water pressure switch.
The controller has 2 terminals, that are prepared for connecting a water pressure switch.
If the switch has been released, because lack of pressure, you will get small yellow warning sign on the
display with the text “Water pressure”. This sign will disappear by itself when the water pressure is back.
