Boiler use

10.0. BOILER USE
Boiler must not be used in flammable and explosive environment. It must not be
used by children or disabled persons (either physically or mentally), as well as by
person without knowledge or experience, unless they are under control or trained
by s person responsible for their safety. Children must be supervised in the vicinity
of the product. Protective gloves must be used (Image 9).
Fuel with max. 25% moisture content may be used.
Before starting up it is necessary to check following:
- if the fresh air access to the boiler room is available (Point 4.0).
- if the boiler and the whole system are properly filled with water and airvented.
- if the safety elements are properly connected and are functioning perfectly:
- closed central heating systems should have safety valve of max. 2,5 bar, thermal
safety valve and expansion vessel of min. volume which is not less then 10% of the
total water quantity in the system.
- open central heating systems should have an open expansion vessel of min.
volume which is not less then 7% of the total water quantity in the system situated
enough over the level of the highest radiator in the system and insulated, if it is
mounted outside of heated space.
- if the mobile elements of the boiler are properly positioned:
- sheet metal protecting cover (ZL-page 3) have to be fixed to the carriers in the
upper combustion chamber.
- pieces of the lower refractory stone have to be situated into the deposits on the
lower wall of the combustion chamber (DS-page 3).
- turbulators (TU-page 28) have to be fixed inside the flue exhaust tubes
(DC-page 3).
- air damper (PZ-page 3) for secondary and primary air.
- if movable elements-two lids of bottom openings of the flue gas chamber and flue
gas tube cleaning lever.
Firing has to be performed according to the instructions described in this manual
(See points 6.0 to 6.4) and Technical manual ''Digital boiler regulation Bio-Tec''.
If you are sure that energy from boiler will be consumed, made firing up for one filling
of the upper combustion chamber.
IGNITION PHASE AND FIRST FUEL CHARGING:
- Open upper boiler doors (and close bottom if they open) (see Image 7)
- Put fine chopped wood to the upper chamber, on refractory stone (chamotte) over
the burner nozzle so that the nozzle is not obstructed, then put crumpled paper
for ignition and fill the top chamber with fuel (split logs). (see Image 7, Image 8).

Technical manual Bio-Tec
Bio-Tec 25
An example of the chimney selection:
-
boiler output:
25 kW
-
Fuel: wood
-
required useable chimney height
: H=8 m
-
required inner chimney diameter
: 18 cm
-
boiler output:
35 kW
-
Fuel: wood
-
required useable chimney height
: H=8 m
-
required inner chimney diameter
: 20 cm
-
boiler output:
45 kW
-
Fuel: wood
-
required useable chimney height
: H=8 m
-
required inner chimney diameter
: 22 cm
Useable chimney height - from flue gas tube connection
to the top of chimney
Inner chimney diameter - interior chimney diameter.
