secondary air opening must be tested, but always mind that flue gas does not escape into the boiler-
room. In this case unhang the chain of draught regulator (close the choker completely).
5. For fire renewal in the morning we open the smoke flap and secondary air inlet on stoking door and we
poke the grate after opening the ash-pan door.
6. Ash-pan door must be permanently closed during the boiler operation.
7. As necessary we empty the ash-pan (by using the gloves)
8. In case the stop valves are used then it is necessary to install the safety valve between the boiler and
stop valve.
9. The filter should be cleaned after the heat test and then before the heating season starts.
7.6 Important warnings
•
The boiler only can be used for the purposes 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 interferences with
boiler construction that could endanger the health of operators or inmates are forbidden.
•
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
•
It is forbidden to use flammable liquids in making fire in VIADRUS HERCULES DUO boiler.
•
it is forbidden to overheat boiler during its operation.
•
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 VIADRUS HERCULES DUO boiler there must not be found any
flammable substances within 1500 mm from the boiler. Use the protection aids.
•
In case the boiler is operated at the temperature lower than 60°C the boiler drum can grow damp
and it is exposed to so called low-temperature corrosion which reduces the boiler drum lifetime.
•
After the end of heating season the boiler including the smoke flue must be properly cleaned.
Lubricate all swivel pins, smoke flap mechanism and other movable components on the boiler
with the graphite grease. The boiler room must be kept clean and dry.
•
Possible signs of corrosion do not mean any fault and they do not influence the boiler function.
•
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.
•
Observation of flame is possible by a slight opening of stoking door. First of all we close the
choker of ash-pan door, then we slightly open the stoking door for approx. 10 sec and then we
can open the door in full. 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 door must
be closed and choker opened.
•
A poor fuel quality can markedly negatively affect the boiler output and emission parameters
7.7 Maintenance
1. During the boiler operation remove the ash from the ash-pan several times a day depending on the type
of used fuel because the full ash-pan prevents the proper distribution of combustion air under the fuel
and can cause an uneven fire penetration through the fuel on the grate. All remnants in the fireplace
especially the slag must be removed before you make a new fire or “revive” the fire in the morning. The
ash must be collected in ashbins made of inflammable materials with cover
. Use the protection aids at
work
and be mindful of your personal safety.
2. The walls inside the boiler, smoke draughts and smoke adapter must be cleaned regularly once a month
(by means of a brush and after the boiler has cooled down and its temperature does not exceed 40
o
C)
when burning coke, hard coal or wood. The cleaning cover in the lower part serves for ash removal from
the smoke adapter. When dismantling the cleaning cover the screw of securing swivel must be loosened
