5.1.2 Operation of boiler by user – Hefaistos P1 E
User guide for controller ST 81 is delivered separately.
Making a fire
1. Check the water quantity in the heating system indicated on the thermo-manometer.
2. Open the stop valves between boiler and heating system.
3. Clean the boiler drum and smoke pathways see chapter 6.
4. Insert kindling on the nozzle through the stoking door – dry, smaller wood chips upright on the duct (it is
necessary to pay attention to flue gases flow continuity), then paper and bigger wood chips.
5. Ignite the kindling in the feed hopper.
6. Close the stoking door.
7. Connect the controller ST 81 to the electricity mains, switch on (position 1 of the switch). By pressing the
button appears on the display. By the next pressing the button
we make a fire (ventilator is activated).
8. Let the kindling flare.
9. Hold the stoking door ajar, wait approx. 10 seconds before you open it fully and then fill the whole feed
hopper with fuel. Close the stoking door.
10. If the temperature of output water exceeds the set production value of 40 °C within 30 minutes the boiler
ignition and its transfer into automatic mode have been successful. Otherwise, repeat the whole process.
Operation
1. Set the required output boiler temperature of (60 – 85 °C, 80 °C is recommended by the manufacturer).
2. During operation it is necessary to feed the boiler with fuel according to the combustion intensity and
need of heat. CAUTION! When refilling the fuel close hold the stoking door ajar, wait approx. 10
seconds before you open it fully and then fill the whole feed hopper with fuel. Close the stoking
door.
3. The boiler working with its full output (2 - 4 stokings) is able to heat up the storage tank volume to
temperature between 80 – 85 °C and then we let the boiler burn out. Then we only take heat from
storage tank by means of three-way valve for the duration that corresponds to the size of the storage
tanks.
Top-fed operation
The top-fed operation can only be used in winter season due to reduction of boiler service life. At the top-fed
operation the combustion process holds more than 12 hours.
Boiler preparation for the top-fed operation:
1.
Replenish the fuel on the glowing layer in the whole volume of the feed hopper.
2. At this operation it is necessary to keep the water temperature 80 – 90 oC. This temperature is achieved
by closing the mixing valve (the ventilator is switched off by the controller)
