3.1 Boiler
The main part of boiler is the cast-iron sectional boiler drum made of the grey cast-iron according to
EN 1561, quality 150.
The pressure parts of boiler meet the demands on the strength according to:
EN 303-5 Heating boilers – Part 5: Heating boilers for solid fuels, hand and automatically stocked, nominal heat output of up to 300 kW – Terminology, requirements, testing and marking
The boiler drum is assembled of sections by means of pressed-in boiler insertions with 56 mm diameter and secured by anchor bolts. The sections create the combustion chamber and the ash pan space, the water space and the convective part. The heating water inlet and outlet are situated in boiler rear part.
The rear part of boiler in its upper part has a smoke extension/adapter and the heating water flange. In the lower part there is the reverse water flange. To the front section there are mounted the stoking and ashpan doors. Under the ash-pan door there is installed a tilting grate.
The whole boiler drum is insulated by the health harmless mineral insulation which reduces the losses caused by heat transmission into the environment. The steel shell is coloured by a good quality comaxit spray.
3.2 Regulation and safety elements
The smoke shutter of the smoke extension/adapter regulates the flue gases outlet volume from the boiler into the chimney. It is operated by a handle with drawbar in the left upper part of boiler next to the stoking door.
The ash pan door choker regulates the combustion air inlet under the boiler grate. It is operated by a draught regulator. Another draught regulator (for 8, 9, 10 sectional boiler) regulates the rear choker. The regulator is set on the same temperature as the regulator in the front part of the boiler.
The stoking door choker serves for secondary air supply into the combustion chamber.
A combined device- the thermomanometer serves for heating water temperature and pressure detection in heating system. The reservoir of thermomanometer sensor is installed in upper part of the front boiler section.

3.3 Equipment for surplus heat removal
The after-cooling loop or the two way safety vent DBV 1 - 02 serves for surplus heat removal in case the water temperature in boiler exceeds 95 °C.
The after-cooling loop is connected to the boiler flanges according to Fig. No. 4, the two way safety vent according Fig. No. 6.
In case of boiler overheating (the output water temperature exceeds 95 °C) the thermostatic valve switches on and the superfluous heat is led off via an after-cooling loop.

In case the system is equipped with a two way safety vent and the boiler becomes overheated (the output temperature exceeds 95 °C) the two way safety vent creates a cold water circuit which is kept until the temperature drops below the limit temperature. At this moment there are simultaneously closed the discharge cooling equipment and the cold water inlet of refilling the system.

Fig. No. 6 The recommended scheme of the two way safety vents DBV 1 – 02 connection
It is necessary to install a safety valve for maximum overpressure of 400 kPa on the system and its dimension must correspond to the rated boiler output. The safety valve must be located directly behind the boiler. Any stop valve must not be located between the safety valve and boiler. If you have any questions, please contact our contractual assembly firm and service organizations.

The two way safety vent DBV 1 – 02 is used as a protection of heating boilers against overheating. In the valve body there is the bleed and supply valve controlled by thermostatic element. When the limit temperature is reached, the bleed and supply valve is simultaneously opened meaning that the cold water is running in and the hot water is running out. When the temperature drops below limit, the bleed and supply valve is simultaneously closed.
Caution! It is not a compensation for safety valve.
In case of two way safety vent reaction, when there is a possibility of boiler having been filled with the water, which does not meet the ČSN 077401 requirements it is necessary to change the water in the heating system so that it meets the ČSN 077401 requirements again.

Installation
Installation can be only carried out by a qualified person. For the correct operation of the thermostatic, two ways safety vent it is necessary to comply with the conditions for its installation and keep the flow directions marking on its body. The safety vent is always mounted in the output pipe of boiler or directly on the upper part of boiler, where the hot water leaves boiler and is transported into heating system. When installing the vent it is necessary to check, if the 3/4“ socket usage, which can be both in pipeline and on boiler, ensures complete immersion of the thermostatic vent element after the vent installation. After the vent has been installed in socket, connect the down pipe, in which the hot water from boiler will flow to drain, to
„C“(see. fig. No. 5). The cooling water inlet, which will cool the boiler after setting the vent in operation, is connected (see fig. No. 6) to „A“ (see fig. No. 5). The filter for mechanical impurities must be installed in the cooling water inlet. It is necessary to connect the pipeline to „B“ (see. fig. No. 5) and the pipeline is to be led into reverse flow pipe of heating system near the boiler (see fig. No. 6).
Regular maintenance
Once a year it is necessary to turn the safety vent’s head to remove possible impurities formed in the vent. Clean the cooling water inlet filter.
In case of using an open expansion tank it is not necessary to use a protecting device against overheating.
Every heat source in an open heat system must be connected with an open expansion tank positioned at the highest point of the heat system. The expansion tanks must be rated in the way that they can contain the changes in water volume resulting from heating and cooling.
The open expansion tanks must be equipped with non-closable bleeder and a overflow pipes. The overflow pipe must be designed in the way that it safely drains off the maximum flow volume entering the system. This can be achieved by rating the overflow pipes by one DN higher than that of the filling piping.
The expansion tanks and their connecting pipes must be designed and positioned in the way that freezing is reliably inhibited.

3.4 Superfluous heat removal equipment- storage reservoirs
In case that the required volume exceeds 300 l we recommend to install a storage reservoir.
Because the minimum output of this boiler is higher than 30% of the rated power we recommend to remove the heat into the storage reservoirs.

4. Positioning and installation
4.1 Regulations and guidelines
The solid fuel boiler can only be installed by a firm holding a valid licence to carry out its installation and maintenance. A project according to the valid regulations must be elaborated for installation. Before the boiler installation on an older heating system the installation firm must flush out(clean) the whole system.The
heating system must be filled with water meeting the ČSN 07 7401 requirements; especially its hardness must not exceed the required parameters

Draught regulator
The instructions for the draught regulator setting are given in the manual attached to the particular regulator.
Assembly tools for brush
Use the leather gloves and common assembly tools for mounting or dismounting of the brush and the spike point (if they are included in the delivery).
Filling the heating system with water:
The water hardness must correspond to ČSN 07 7401 and it is inevitable to treat the water according to Chap. no. 5.1. in case the water hardness is unsatisfactory.
The heating systems with an open expansion tank allow the direct contact between the heating water and the atmosphere. During the heating season the water expanding in the tank absorbs the oxygen, which increases its corrosive effects and at the same time the water evaporates heavily. Only the water treated to the values according to ČSN 07 7401 can be used for refilling.
The heating system must be thoroughly flushed out in order to wash out all impurities.
During the heating season it is necessary to keep a constant volume of heating water in heating system and be particular about bleeding the heating system to avoid the air suction into the system. Water from the boilers and heating system must never be discharged or taken for usage except in cases of emergency like the repairs etc. Water discharge and filling with new water increases the danger of corrosion and scale development. In case we have to refill the heating system with water we only do this operation when
the boiler is cold in order to prevent its sections from getting broken.
After boiler and heating system refilling operation the all joints must be tested for tightness.
When using the two way safety vent DBV 1 - 02 the cooling water is added gradually to the to the reverse water.
The assembly and stoking test completion must be recorded in the “Guarantee certificate”.
21
6. Commissioning
The boiler can only be commissioned by professional assembly firms authorized to do this activity.
Before the boiler is put into operation it is necessary to check:
1. Filling the heating system with water (thermomanometer check) and the system tightness.
2. Connection to the chimney– this connection can only be done with the agreement of a chimney- sweepers´ firm (chimney revision) measure the chimney draught according to tab.no. 1,2,3 depending on particular fuel.
3. Draught regulator and thermostatic valve functionality.
1. Fire a boiler.
2. Bring the boiler to the necessary operating temperature. The recommended output water temperature is
80 °C.
3. Adjust the draught regulator incl. the chain length (according to enclosed draught regulator manual).
4. Check the functionality of protecting device against overheating (after-cooling loop or the two way safety vent DBV 1 - 02)
5. Operate the boiler in operating condition according to relevant standards.
6. Check again the boiler tightness.
7. Acquaint the user with operation.

1. Check on the thermomanometer the volume of water in the heating system.
2. Open the stop valve between the boiler and the heating system.
3. Clear the grate, the ash pan, smoke flues and the boiler walls. (after the clearing you must check the tightness in the smoke extension).
4. Through the ash pan door& the furnace door lay out the kindling and wood on the cleared grate within the whole depth of the boiler.
5. Bring the smoke shutter in the smoke extension/ adapter into the open position and close the stoking door.
6. Fire the kindling through the open ash pan and furnace door.
7. Shut the ash pan door& the furnace door and open fully the choker. At the 8 – 10 sectional boiler also the rear choker.
22
8. On the flaring wood load a thinner layer of basic fuel.
9. After its good ignition load other fuel up to the lower edge of the stoking door and level the fuel into a uniform layer along the whole depth of the boiler.
10. As soon as the fuel gets into a dark red glow by means of a tool open slightly the stoking door choker of the secondary air inlet at the stoking door.
11. After the flames get yellow close the stoking door choker of the secondary air inlet.
Operation
1. After having achieved the heating water temperature regulate the combustion air inlet. The boiler output is roughly regulated by the change in chimney draught by means of the smoke shutter in the smoke extension. The fine output regulation is done by means of the choker which regulates the air inlet under the grate either manually or by means of the draught regulator. The draught regulator must be set in a way making sure that the choker in the ash pan door is almost closed at the moment the heating water temperature has been achieved.
2. According to the heat need and the burning intensity the boiler must be refilled with fuel during the operation. Stoke in the way making sure that the fuel layer is evenly high along the whole depth of the boiler.
3. When using coke, hard coal and wood the stoking door choker at the secondary air inlet must be partially open during the whole time of gases and flames development from the freshly stoked fuel.
4. When switching over to the night inhibited operation clear the grate, let the freshly stoked fuel well burn up and then subdue the boiler output by throttling the chimney draught by means of the smoke throttle in the smoke extension and throttling the stoking door choker at the secondary air inlet. The degree of the smoke throttle and stoking door choker opening must be tested but it is necessary to be particular about no flue gases escaping into the boiler room. In this case the draught regulator has to be disconnected (the choker closed completely).
5. The boiler operation restoration in the morning is to be done by opening the smoke throttle and stoking door choker and poking the grate after the ash pan door opening.
6. The ash pan door must be permanently shut during the boiler operation.
7. According to the need clear the ash pan (it is necessary to use the gloves).
8. In case of use of stop valves the safety valve should be installed between the boiler and the stop valve.
9. We recommend cleaning the filter after the heating test and subsequently before the heating season.
1. The boiler only can be used for the purpose that it is destined for.
2. The boiler only can be operated by adult persons who are familiar with this operation manual. In is inadmissible to leave the children at the boiler unattended by adults. The interferences with boiler that could endanger the health of operators or the roommates are impermissible.
3. The boiler is not destined for the use by persons (incl. children) whose physical, sensual or mental disability or lack of experience and knowledge prevent them from a safe use of the appliance unless they are supervised or if they were not instructed on the use of appliance by a person responsible for their safety.
4. Children should be supervised in order to ensure that they do not play with the appliance.
5. The boiler is not destined for the use by persons (incl. children) whose physical, sensual or mental disability or lack of experience and knowledge prevent them from a safe use of the appliance unless they are supervised or if they were not instructed on the use of appliance by a person responsible for their safety.
6. Children should be supervised in order to ensure that they do not play with the appliance.
7. If there occurs a danger of inflammable vapours and gases development and penetration into the boiler room or at works accompanied by temporary development of the fire or explosion danger (gluing of floor covering, painting with combustible painting colours), the boiler must be duly closed down before the works start.
8. It is FORBIDDEN to use flammable liquids for VIADRUS HERCULES U 26 boiler ignition.
9. During the operation it is FORBIDDEN to overheat the boiler.
10. On the boiler and within the distance shorter than the safe distance from it there must not be put any objects made of flammable materials.
23
11. When clearing ashes at VIADRUS HERCULES U 26 boiler there must not be put any flammable materials within minimally 1500 mm distance from the boiler.
12. The space at the point of choking valve rotation of the ashtray door must be cleaned in case of clogging with fuel, ashes or other impurities in order to avoid its rubbing thus wrong functioning.
13. When operating the boiler at the temperature lower than 60 °C the boiler drum can get bedewed which means the low-temperature corrosion and reduction of boiler drum lifetime. Therefore we recommend to operate the boiler at the temperature of 60 °C and higher.
14. After the heating season termination it is necessary to clear thoroughly the boiler, smoke-flues and the smoke extension/ adaptor. Lubricate the pivots, the smoke throttle mechanism and other movable parts at the boiler with the graphite grease. Keep the boiler room clean and dry.
15. Possible corrosion marks on the boiler drum don’t mean a defect and they do not affect the boiler function.
16. It is necessary to install a safety valve for maximum overpressure of 400 kPa on the system and its dimension must correspond to the rated boiler output. The safety valve must be located directly behind the boiler. Any stop valve must not be located between the safety valve and boiler. If you have any questions, please contact our contractual assembly firm and service organizations.
9. Maintenance
1. During the boiler operation remove the ashes from the ash pan several times a day depending on the kind of the used fuel, because the full ash pan prevents the combustion air from the proper distribution under the fuel and causes an uneven fire penetration through the fuel on the grate. We remove all remains from the combustion chamber, especially the clinker before every new firing and when restoring the boiler operation in the morning. The ashes must be put into fire-resistant covered containers. Use
the protective means at this work and mind your personal safety.
2. When using the coke, hard coal and wood clear regularly once a month the walls of the boiler inside the combustion chamber 1x, the boiler smoke draughts and the smoke extension/ adaptor (this by means of a brush into the cooled down boiler where the temperature does nor exceed 40 °C).
3. If in case of using the fuels with a more intensive gases development the tar deposit accumulates on the combustion chamber walls we remove it by means of a scraper or by burning dry hard wood (or coke) while bringing the boiler to the maximum working temperature.
4. After the heating season termination treat (by using the Vaseline) the pivots/ swivel pins of the smoke throttle and all doors.
