Boiler use
- Close upper boiler doors. (see image 7)
- Turn the MAIN SWITCH on. (see Point 7.0)
- Push the button START (the LED diode flutters). (see Point 7.0)
- Open the middle door and ignite paper (see Image 7)
- Couple minutes after fine chopped wood starts burning, close the middle door.
(see Image 7)
- Push the button START (the LED diode lights) (see Point 7.0)
- (Only for Bio-Tec 25) place the button RP (see page 3) into position " "
- (Only for Bio-Tec 25) leave the button RP (see page 3) in position " " at least 1
hour or longest to the next charge with wood and then restore it in the left position.
The above actions are for ignition of the boiler from cold state (without glow).
These measures should be implemented always when we don’t have, or don’t
have enough glow, and when we will load the wood.
After the regulation starts to display the lack of fuel , the fuel should be
refilled (if it is necessary to continue the heating process)-BEFORE REFILLING,
press START button ones.
FUEL REFILLING PHASE:
- open the upper boiler door (see Image 7)
- align glow with poker
- insert fuel (recommended to fill the full firebox) (see Image 8)
- close the upper boiler door (see Image 7)
-press button START for second time. (see Point 7.0)
NOTE:
- During the process of refilling the fuel the main switch of the boiler has to be
turned on. When the firing proces is
over
we can turn off the main switch, but first
it is necessary, after the indication ''FUEL'' is turned on, to wait that the boiler
cool down under 65°C and the glow disappear in combustion chamber (see point
7.0.).

Connection to the chimney, fresh air opening
3.0. CONNECTION TO THE CHIMNEY
Properly calibrated and built chimney is the precondition for a safe operation of the
boiler and economic heating. The chimney has to be good insulated, gas-proof and
smooth. On the lower part of the chimney, a cleaning door has to be built in. Brick
layed chimney has to have 3 layers with an stone wool thermal insulation in the
middle. The thickness of the insulation should be 30 mm, if the chimney is situated
inside the building, i.e. 50 mm if the chimney is situated outside the building.
Inside
chimney diameter dimensions depend on its height and on the boiler
capacity (Image 5.).
The temperature of the flue gases on their exit point should be
minimum 30°C higher then the temperature of their condensating point. The choice
and the construction of the chimney should be performed by an authorized person.
Minimal distance between boiler and the chimney is 500 mm. The flue gas tube has
to have an inclination of 30-45° (Image 4.). In order to unable entering of the
condensate from the chimney into the boiler, 10 mm of the flue gas tube length has
to be inserted deaper inside the chimney.
It is recommended to insulate the
chimney connection tube with a mineral wool
of 30-50 mm thickness. All
installation works must be made in accordance with valid national and European
standards.
At connecting a boiler to the chimney, flue
gas tubes
and elbows must
not pass behind the fan since in that case the cleaning and maintenance will not be
possible. An example of
incorrect
position of
flue gas tubes
and elbows in relation to
the fan is presented at the
