3. Description
3.1. Boiler construction
The boiler body (Fig. No.1) consists of sections assembled by means of forced-on insertions and is secured
by anchor bolts. Boiler has a three-draught construction and the sections create the combustion space and the
convection part, inside then the boiler water space. The tightness of boiler gas combustion space is guaranteed
by boiler cement applied to sections seating faces and to circumference of individual section joints.
On the front section there are fixed sealing and burner plates that either can be opened to right or left hand
side according to boiler room layout. This must correspond with screw suspensions positioning (lugs).
The openings G 2"in the front section are closed with plugs G 2". The upper plug has a boring G 1/2“ for
the basin of regulation and safety thermostat. In the left upper riser of the section there are two openings G
1/2" for thermometer and pressure gauge sensors.
The input and output of a heat carrying substance is situated at the rear part of boiler and it is carried out with
flanges and a mouthpiece DN 80. At the lower flange with a mouthpiece there is positioned the filling &
discharging cock. In the opening for heat carrying substance input (under the flange) there is positioned a
restrictive insertion (5 – 10 sections and 11 – 14 sections), which streamlines the water flow in boiler.
The combustion gases from the boiler are led/ taken away through a flue orifice with an explosion shutter
which at the same time serves as a small cleaning cover. At the flue orifice there are measuring points for
temperature and combustion gases analysis.
The boiler body is fully insulated by plates made of mineral insulation . The steel shell of boiler is surface
treated by comaxite paint. In the upper front part of boiler there is positioned the electro-panel with regulation,
safety and control elements.

4. Positioning and installation
4.1. Boiler standing in boiler room
The boiler is designed for positioning in closed
areas with aggressiveness degree between a little up
to moderately aggressive and in terms of
electrotechnic regulations in a common
environment (ČSN 33 2000 – 7
– 701:1997). It agrees with the use in rooms
separated from housing room itself (Declaration
91/93 Coll.., ČSN 07 0703:1986 Gas boilers).
Boiler noise level does not exceed the maximum
level of LA= 75 dB(A) - (the real value depends
on the type of used burner : for recommended
types it ranges between 60 – 70 dB).
The boiler must be positioned on a fireproof pad
or a sustaining wall approx. 50 mm high. In front
of boiler there must be left a free handling area
minimum for the boiler depth + 500 mm, from one
side 600 mm (access to the back).
When positioning the boiler there must be
respected the layout requirements of selected
type of burner (gas inlet and others.)
L of boiler + min. 500
*) It is necessary to respect the
selected type of burner layout
requirements ( gas inlet , burner
length etc.)
Fig. No.5 Boilers positioning in boiler room
For safety reasons at the installation there must be observed the distance of 200 mm from flammable
substances (ČSN 06 1008:1997 – Fire safety of local appliances and heat sources). For easily flammable
substances it means those that are quickly self-burning also after removing the source of inflammation (like tar
paper, cardboard, asphalt and tar paper, wood and hardboards , plastic substances, flooring) the distance gets
doubled. A safe distance must be doubled also in case that the building material flammability degree hasn’t been
proved.
In case that there is a danger of a temporary intrusion of combustible vapours or gases into the boiler room or
at the works at which there temporarily occurs the fire & explosion danger (gluing the flooring, coats with
combustible paints ) the boiler must be put out of operation in time and before the works commencement.
Warning:
No subjects made of flammable substances (see Fig. No.5) are allowed to be put on the boiler and within a
distance smaller than the safety distance.
Filling the heating system with water. The heating system must be thoroughly flushed out so that all
impurities that could be deposited in distribution system and radiators are washed out because otherwise they
could damage the pump. Water for filling the boiler and heating system must be clear and colourless , with no
suspended substances, oil or chemically aggressive substances. The circulation and filling water parameters must
correspond to:
Tab. No.3 The highest permissible values of heating water according to ČSN 07 7401:1992
hardness (mmol/l) 1
Ca2+ (mmol/l) 0,3
Total Fe + Mn concentration (mg/l) 3*
*recommended value
In case that the water hardness is unsuitable it must be adjusted. Not even heating the water with higher
hardness several times will prevent the soils precipitation on the boiler body walls. Precipitation of 1 mm calcite at
a given point will reduce the passage of heat from metal to water by 10%.
During the heating season it is necessary to keep a constant heating water volume in the heating system and be
particular about venting the heating system. Water from boiler and heating system must never be discharged or
taken for use except for inevitable cases like repairs etc. By discharging the heating water and filling the system
with new water the danger of corrosion and scaling is increased. In case that it is necessary to replenish water in
heating system, we only refill it in a cold boiler, otherwise the sections could crack.

The assembly process is stated in „ VIADRUS G 300 boiler assembly manual “
6. Commissioning
Putting the boiler into operation, setting the heat output and any intervention into the electrical part of
boiler or connection of further control elements can only be done by service organization authorized to do
the service works and an authorized firm for servicing the burner being operated.
1. Burner installation and assembly, its adjustment and putting the boiler with a burner into operation must be
confided to the care of a burner supplier ´s service firm . The service firm will give the user a training in
operation and provide him with burner use manual and guarantee plus after-guarantee repairs.
2. Before putting the boiler into operation a record must be made in Inspection book.
6.1. Checking activities before initiation
Before putting the boiler into operation it is necessary to check:
a) filling the heating system with water (thermo-manometer check ) and tightness of the system
b) setting the boiler thermostat stage II. (rated power/ nominal output) to 60 - 90 oC (within the range 60 - 115 °C
in case that the boiler is operated above 95°C).
c) opening all slide-valves and valves between the boiler and heating system
d) opening the fuel inlet
e) inlet pressure of fuel before entering the boiler according to the burner documentation
12

f) connection to the electricity network 230V/380V 50 Hz/TN-S
g) connection to the chimney (the necessary chimney draught is 0,5 mbar).
h) max. overpressure in combustion chamber is 2 mbar. The probe positioned on burner plate serves for
overpressure measuring in combustion chamber.
Setting the regulation elements:
-regulation thermostat stage I. (reduced output) – permanently set by manufacturer to 95°C
-safety thermostat - permanently set by manufacturer to 105°C (to 120°C in case that the boiler is operated
above 95 °C)
6.2. Boiler conversion from „ liquid fuels“ to „ gas fuels“ and back
The boiler conversion from „ liquid fuels“ to „ gas fuels“ and back doesn’t require any adaptations apart from
the burner and adequate flange exchange for a burner. Before the conversion we recommend to check the body, the
combustion gases routes and their thorough cleaning.
This conversion (burner exchange ) will only be required by a customer at a contractual service firm –
organization entitled to be engaged in this activity.
7. Boiler operation by user
The boiler works automatically according to the regulation elements setting and users only do the following
operating activities that they are obliged to familiarize with before putting the boiler into operation as follows:
1. Switching on and switching off the boiler by means of network switch on the boiler electro-panel.
2. Setting and checking the required heating water temperature within 60 – 95°C limits (to be set on115 °C in
case that the boiler is operated above 95°C ).
3. Unblocking the safety thermostat. In case that the boiler is switched off by a safety thermostat, the signal lamp
on electro-panel is alight thus signalling that the temperature has been exceeded. The user can unblock the
thermostat by means of the pushbutton "unblocking" at the safety thermostat positioned at the rear panel of
control box.
4. ressure check in heating system

„ The Operation and installation manual is a part of delivery in case that a equithermal regulation
is required “.
IMPORTANT WARNINGS :
1. The boiler after initiation works automatically. It only can be operated by adult persons familiar with
this manual and the burner operation manual.
2. The boiler must be operated according to the manual and related standards.
3. The air of combustion must not contain a high moisture and dustiness. If their occurrence cannot be
excluded in the environment related to the boiler location there must be brought the air of combustion into the
boiler room directly from outdoor environment .
4. The boiler room must be kept in a clean and dust-free condition. From the boiler room area there must be
excluded all sources of pollution and during the works (insulation works, boiler room cleaning) that cause the
dustiness the boiler must be put out of operation. Even a partial burner clogging with dirt devalues the
combustion process and endangers an economical and reliable boiler operation.
5. To prevent the boiler from retting followed by low-temperature corrosion at the places where a more
permanent run at lower temperatures can be expected (transition periods, at the heating system with a large
heating water volume, law-temperature regime etc.) it is necessary to ensure that the return water temperature
does not drop below 50 °C. The best way is the creation of boiler own circuit .
6. Adjustment of burner stage I. (reduced output ) must be done with regard to the combustion gases temperature
in a way making sure that it doesn’t drop below 130°C.
7. Water from boiler and heating system should never be taken for use neither discharged apart from the
indispensable cases like system repairs. The water discharge increases the corrosion and scale formation
danger. If it is necessary to refill water always chemically treated in heating system then we only refill the
cold boiler in order to avoid the boiler sections breaking.
8. If there occurs the boiler failure condition, the lamp signalling the burner failure lights up at the boiler
electro-panel. In case of electricity outage the burner is switched off and after voltage recovery in el. network
there will automatically run a new burner start.
9. The burner operation failures are in detail described in burners operation manual , including the ways of their
elimination and they must be followed.
10. In case of a long-term shut-down of a boiler this boiler must be disconnected from el. network.
11. In case that there occurs the danger of flammable vapours or gases development and their intrusion into
the boiler room , or at the works where there temporarily occurs the fire or explosion danger (gluing the
flooring, painting with flammable paints ), the boiler in time and before works initiation must be put out
of operation.
12. No objects made of combustibles are allowed to be put on boiler and within a distance lower than a
safety distance from the boiler.
13. The user is obliged to confide the commissioning, regular maintenance and failures elimination only to
the care of a professional contractual service accredited by ŽDB GROUP a.s. Bohumín, the boilers
manufacturer, Heating technique plant VIADRUS, otherwise the boiler proper function guarantee
doesn’t apply. “VIADRUS G 300 boiler quality and completeness certificate “after having been filled in
by contractual service organization serves as the “ Guarantee certificate“.
14. On the boiler there must be carried out once a year a regular maintenance according to the next chapter.
If you fail to meet these conditions you cannot requisite the guarantee repairs.
