and if it be to the contrary the ventilator is automatically switched off after 15 minutes. When making
fire the ventilator is set to 50 % nominal ventilator output (set by the manufacturer). In case the fuel
has changed for wood pellets this output must be set to 20 % (parameter P 22).
−
When making fire the height of fuel must be kept approx. 2 cm under the edge of the cast iron grate.
−
If after 15 minutes the fuel is sufficiently flaring switch on QAA 88 device by pressing the right-hand
key ESC and cursor will move into Auto position
−
If after 15 minutes the fuel does not flare up sufficiently switch on the ventilator again for the
necessary period of time and then switch on QAA 88 device by the right-hand key ESC; the cursor
will move into Auto position
−
Now the boiler is in the automatic regime.
−
WARNING!
If before the QAA 88 device turning–on the ventilator is still switched on in the
manual regime, (display of QAA 88 device is flickering i.e. 15 minutes have not elapsed since
pressing the blue button) switch off the ventilator by means of blue button and only then
switch on the QAA 88 device.
2. Check the boiler tightness again.
3. Carry out the heat test according to relevant standards (see the Guarantee certificate).
4. Make the user acquainted with boiler attendance.
5. Make a record in the Guarantee certificate.

6.8 Important warnings
•
The boiler must not be used for other purposes than those it is designed for.
•
The boiler only can be operated by adults who are acquainted with this service manual. It is
forbidden to leave unattended children in the vicinity of operating boilers.
•
The boiler is not destined for use by persons (including children) whose physical, sensory or
mental disability or lack of experience and knowledge prevent them from a safe use of the
appliance if they are not supervised or were not instructed regarding the use of the appliance by a
person responsible for their safety.
•
Children should be watched to make sure that they do not play with the appliance.
•
If there occurs the danger of flammable vapours or gases development and their penetration into
boiler room or during the works that are accompanied by temporary danger of fire or explosion
(gluing the flooring materials, painting with combustible paints etc.) the boiler must be put out of
service prior to the start of such works
•
When transporting fuel into combustion chamber before making a fire the volume of fuel in retort
must be checked visually and not by putting hands into fireplace. There is a danger of injury
caused by rotating worm shaft.
•
It is forbidden to use flammable liquids in making fire in VIADRUS HERCULES DUO boiler.
•
Observation of flame is possible by opening the choker of ash-pan door (manual operation). Keep
in mind that this situation is associated with an increased danger of sparks dispersion in the
boiler room. Immediately after the visual check of flame the choker must be properly closed.
•
During the VIADRUS HERCULES DUO boiler operation it is forbidden to overheat it in any way.
•
It is forbidden to put any things made of flammable materials on the boiler or within the distance
less than the safe distance.
•
When removing the ash from boiler there must not be found any flammable substances within
1500 mm from the boiler. The ash must be collected in a non-flammable ashbin with a cover. Use
the protection aids.
•
After the end of heating season the boiler including the smoke flue must be properly cleaned. The
boiler room must be kept clean and dry.
•
It is forbidden to interfere with construction and electric installation of boiler.

In case the two-way safety device has responded to refill with water not conforming to
Č
SN 07
7401 it is necessary to treat the water in the system so that it again conforms to this standard.
•
The safety valve of max. 250 kPa overpressure must be installed in the system and its dimensions
must correspond to boiler nominal output. In case of further questions please contact our
contractual installation firms and service organizations.
•
A poor fuel quality can markedly negatively affect the boiler output and emission parameters.
