Warning!
After the first heating up, there can be condensation and condensate may leak. This is not a defect
Condensation disappears after longer heating. When burning smaller wooden waste it is necessary to check
the temperature of flue gas which must not overcome 320°C. Otherwise the fan can be damaged. Creation of
tar and condensate in the feed hopper is a phenomenon accompanying wood gasifying.
If the boiler was out of order for a longer time (switched off,broke down), it is necessary to use extreme
caution when putting into operation again. In not working boiler, the pump can be blocked, water can leak or
the boiler could get frost in winter.
Heating up and operation
Before burning the fuel open the fuel cut-off flap pull the pull rod of the flap and set the flue thermostat to 0°C.
Through the upper door put dry wood chips on the heatproof shaped piece perpendicularly to the channel to
leave 2-4 cm gap between the fuel and channel for transition of flue gas. Put paper or wood wool on the chips,
then chips again and a bigger amount of dry wood. After burning the fuel switch on the fan and close the fuel
cut-off flap. On the thermoregulation valve set the demanded temperature of water (80- 90°C). After proper
start fill in the whole fuel bin and set up the fuel thermostat into operation position.
CAUTION: During the operation the pull rod of fuel cut-off flap must be shifted in otherwise the fan can be
damaged.
To gasify wood, there must be a reduction zone in the boiler (a layer of charcoal on the ceramic shaped piece
in the feed hopper). The layer can be created by combustion of dry wood of proper size. When wet wood is
burned, the boiler is not working as a gasifying boiler and the consumption of wood rises, output is lower than
demanded and the service life of boiler as well as that of flue is shortened. If the draft is as specified, the boiler
works up to 70% of output even without a fan.
Electromechanical output regulation
Output is regulated by flap on the rear part of boiler, which is controlled by the output
regulator. This regulator opens or closes the flap automatically, according to adjusted
outlet water temperature (80 - 90°C). It is necessary to set the regulator carefully, because
it regulates output and also subserves important function of boiler protection against
overheating. Fasten the chain by bigger hook to mounted and complete regulator. Set the
temperature on regulator to 80°C (for setting of temperature, use the red scale). Open the
inlet flap to maximum by fastening it to the second end of the chain. Heat the boiler up.
When the water temperature reaches 80°C, after few minutes, adjust the chain length to
let the door open for 3-5mm. Ensure the adjustment by adjusting screw on the flap. If the
boiler temperature differs from adjusted one during the operation, change the chain length
adequately. Consider also another influences, that may have consequences on boiler
temperature (fuel amount, ash, position of secondary air flap, persistence of boiler and
whole system, etc.). Check protection against overheating by testing the regulator´s
function already at the temperature of 90°C. The regulation flap has to be almost closed at
this temperature. It is necessary to test adjustment of regulator. Position of regulation flap
can be seen from the rear part of the boiler. Fan is controlled by boiler thermostat on the boiler panel,
according to adjusted outlet water temperature. The temperature set on the boiler thermostat should be lower
for 5°C than temperature on the thermoregulator. The flue gas thermostat is also placed on the panel. It serves
to shut down the fan after burning-out of fuel. During the heating up, set it to the „0°C position“. After
sufficient flaming up, set it to the operation position to let the fan run and to turn it only after burning-out of
fuel. It is necessary to find the optimum position of the flue gas thermostat adequately to the sort of fuel,
chimney draught and other conditions. Watch the outlet water temperature via thermometer. Also the non-
return safety thermostat is placed on the panel (Standard version).
Refueling
For refueling first open the fuel cut-off flap by the pull rod, do not stop the ventilator. Wait for some 10
seconds, then slowly open the feeding door so as accumulated flue gas can be draught to the flue. During
heating keep the feed hopper always full. To prevent smoke, stoke other fuel only after the original charge is
burnt out at least to 1/3 of the content. Then cover live coal with a broad log and fill in as usually. The fuel
must not be pressed over the jet as this could cause extingiushing the fire.
CAUTION! During operation the pull rod of fuel cut-off flap must be shifted in, otherwise the fan can be
damaged.
