The boiler must be o erated in accordance with these instructions to ensure the quality and the secu-
re function of the boiler. The boilers are allowed to be attended only by adult ersons.
During the assembly lay under the rear boiler art to 10 mm.
NOTICE
During the first firing u a condesation and a condensate outflow a ears – it is no default.
In case of combustion of small waste wood the waste gas tem erature must be checked – it is not
allowed to exceed 320 °C – this can cause a boiler damage.
The a earance of the tars and condensates on the fuel ho er is a normal rocess that accom a-
nies the wood gasification.
Firing-up and operation
Before the firing-u the firing safety valve must be o ened ulling out the ull rod /17/. Set waste gas
thermostat on zero.
Through the u er door /2/ ut dry small firewood on the fire resistant sha ed ieces /5/ er endicu-
lar to the channel /12/ with a ga 2 - 4 mm between the fuel and the channel because of the flue gases
assage. Then a er or woody wool and small firewood again, after this bigger amount of dry wood.
After firing-u wait for max. 8 min., then switch on the ventilator /4/ and close the firing safety valve via
its ull rod /17/. On the ower regulator /22/ set the required warm water tem erature. After the firing-u
fill the fuel container with wood. Set the thermostat on 100-150 °C (on the oint).
For the gasification it is necessary to establish and to kee a reduction zone of glowing charcoul on
the ceramic sha ed ieces in the fuel container. This condition can be reached burning dry wood of ade-
quate dimensions. If using wet wood, the boiler does not o erate as a gasification boiler, the wood con-
sum tion is much higher, the required ower out ut cannot be reached and the durability of boiler and
chimney will be reduced. The s ecified draught of the chimney ensures the boiler nominal ower 70 %
even without a ventilator.
Power regulation – electrical-mechanical
The ower out ut is controlled with a safety valve /8/ o erated with the ower regulator FR 124 /22/,
which automatically o ens or closes the safety valve according to a set out ut tem erature of the water
(80 – 90 °C). When setting the ower regulator, much attention should be aidn to this activity, because
the regulator has another funtion else than ower regulation – it also secures the boiler against overhe-
ating.
When setting this regulator HONEYWELL ty e FR 124, the enclosed installation and setting-u
instructions should be followed. The rotection against overheating and the regulator function should be
checked at the water tem erature 90 °C. In this stage the regulating safety valve /8/ must be nearly clo-
sed. The set oint of the ower regulator must be checked. The valve osition can be seen at the back
of the ventilator. A controlling thermostat on the boiler control anel regulates the ventilator according to
the set tem erature. A tem erature on the controlling thermostat is to be set by 5 °C lower than that on
the ower regulator FR 124. (A oint marked on the thermostat scale). The working tem erature of
water must be checked on a thermometer installed on the control anel.
Filling of wood
When filling the wood into the fuel container, following ste s must be done: first o en the valve /13/
with its ull rod /17/ (do not switch off the exhaust ventilator). Wait ca. 10 sec. and then o en slowly the
filling door /2/ in such a way, that the cumulated gases flow into the gas flue. After this the filling door can
be fully o ened. The fuel container shoul be filled com letely. To eleminate the smoke esca e, the filling
u should be erformed after the wood is burned out at least to a third. Put a large billet on the glowing
charcoal and then fill u normally to minimize immediate burning out and roduction of the combustion
waste roducts. During the heating the firing safety valve /13/ must be closed – otherwise the ventilator
can be damaged.
