IGNITION
We plug the boiler in the electric mains via a power cable.
The ignition valve and the upper door are opened and we put dry splinters over the fire-resistant forms perpendicular to
the nozzle, so that there is a 2-3 cm distance between them (the splinters do not block the nozzle).
Paper, splinters and logs are placed on top of them, we light the fire and wait for the wood to start burning, then we add
more logs and, after these have are aflame as well, we close the door of the upper fuel compartment, close the ignition
valve and switch the fan on from the control panel.
The boiler thermostat is adjusted at 80 degrees.
After about 30 minutes there is a layer of live coals on the ceramic plate that is thick enough for the purpose of the normal
boiler operation, therefore we can fill the whole chamber with fuel.
CAUTION!
•
During operation, it is not permitted to open the door of the upper chamber when the fan is on and the ignition valve is
closed.
fILLING UP WITH fUEL
Before every fill-up with fuel we have to: first, we have to switch the fan off; secondly, we open the ignition valve; thirdly,
we open and leave ajar the door of the upper fuel chamber and hold it this way for 20 seconds or so till the gases have
been pulled away through the chimney, and then open it fully.
Fuel is poured till the chamber is full, the door and the ignition valve are closed and the fan is turned on.
When filling up with fuel the following sequence must be kept:
1. The burning material must be placed in a longitudinal manner over the chamber nozzle, and in a way such that none of
the splinters get stuck in it.
2. Special attention must be paid not to block the closing of the ignition valve.
3. When we fill up with big logs and small wooden splinters, the latter must be placed at the end of the chamber/compart-
ment, and the big and moist ones - in the middle.
This is done to prevent forming a cavity over the nozzle.
MODES Of OPErATION
Optimal mode of operation
The optimal mode of work of the boiler is achieved when the temperature of the outgoing water is above 75 degrees.
If this temperature is lower, and especially when this value is less than 60 degrees, there is a partial distillation, formation
of tar and condensation, which prevent the boiler from proper operation.
If the boiler is installed in a room with forced circulation, the pump’s operation must be coordinated with the temperature
of the outgoing water, i.e. the pump must switch itself on when this temperature exceeds 70 degrees.
Air
The air enters the boiler via the fan where it is heated and distributed as primary and secondary flows.
The heated primary flow enters the fuel chamber, where it dries the fuel, causes pyrolitic distillation and thus the wooden
gas is formed.
The secondary airflow, also heated, is passed in the ignition nozzle, mixes with the wooden gas and ensures the full burning
of all flammable ingredients.
The air valve does the division and regulation of the primary and secondary airflows.
It is produced from the factory at 33 mm (see page 22) and fixed with screw M5.
To increase the primary and, respectively, reduce the secondary airflow, it is necessary to loosen screw M5 and push the air
valve at a distance less than 33 mm.
