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 regulation is conducted with a flap on the rear side of the boiler wich is controlled by a
thermoregulation valve. The valve opens or closes the flap automaticly by set up outlet temperature
(80 - 90°C) of water. Pay special attention to setting up the thermoregulator as this except the
regulation has another important function - protection the boiler against overheating. For setting
up follow the instructions for aseembly and set up of the regulator. Check the protection against
overheating by verifying the function of regulator with 90°C water. For this temperature the
regulation flap must be almost closed. Set up of the regulator must be tested. The position of the
regulation flap can be watched from the back side of the fan. With the boiler thermostat located on the
panel of the boiler you can control the fan by outlet temperature of water. The temperature on the
regulation thermostat should by in 5°C lower than the one on the thermoregulator. On the panel there
is also a flue thermostat serving to stop the fan after burning out of the fuel. For heating up, set it up to
0°C. After proper heating up set it up to operation position so that the fan is working and is not
stopped until burning out of fuel. The optimum position of the flue thermostat must be watched by the
kind of fuel, draft and other conditions. Check the temperature of outlet water on the
thermomanometer. On the panel there is also a safety non-returnable thermostat.
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.
