1.2 IMPORTANT INFORMATION

• Installation, heat–up test and user training must be performed by the technician trained by

producer. The technician must fill the protocol about the installation of the boiler.

• By gasification of wood it comes to creation of tar and condensates (acids) in the fuel tank.

Due to this there must be a mixing device installed behind the boiler to keep the minimum temperature of return water at 65 °C. The temperature of water in the boiler during its operation must be within the range of 80 – 90 °C.

• The boiler must not be permanently operated within the output lower than 50 %.

• If the circuit pump is being used, its operation must be controlled by a separate thermostat

to ensure the prescribed minimum temperature of the return water.

• Ecological boiler operation is related to its nominal output.

• It is recommended to install the boiler together with the accumulation tank and mixing de-

vice. This ensures the fuel saving of 20 – 30 % and longer lifetime of the boiler and chimney.

• If it is not possible to connect the boiler to the accumulation tank, it should be connected

with at least one equalization tank with the volume of approximately 25 l / 1 kW of the boiler´s output.

• By the operation with lower output (summer operation and D.H.W. preparation) it is neces-

sary to heat the boiler up every day.

• Only the dry fuel of 12 – 20 % moisture can be used (by the higher moisture of fuel is the

boiler output decreased and its consumption increased).

• Due to the economical operation and correct functionality it necessary to choose an appro-

priate boiler output. The nominal output of the boiler has to be adequate to the temperature loss of the heated object.

WARNING! When the boiler works in PELLET mode, the primary and secondary air flaps must be closed.

ATTENTION: The boiler must be used only for the purpose that it is intended for and

only in the way given in this manual.

The warranty for the boiler is not valid:

• if it is not operated with the prescribed fuel.

• if no mixing device Regumat ATTACK–OVENTROP is installed in the system to ensure the re-

turn water temperature of at least 65 °C during the boiler operation.

• if no functional thermostatic valve is installed on the aftercooling circuit (WATTS STS20) of

the boiler, connected to the cold water inlet.

This device is not supposed to be used by persons (including children) with physical, sensual or mental disability or insufficient experience due to which they are not able to use the device in a safe way without being supervised or instructed about the boiler operation by the person responsible for their safety. Do not to allow the children to play with the device.

If the power supply cable is damaged, it must be replaced with a special cable available by producer or by a service technician!

1.3 SAFETY

This manual uses the following warning signs to illustrate the severity of the impending danger and important safety information:

WARNING!: Imminent dangerous situation, if not taken the right steps, may occur in serious injury or property damage. Act under the above instructions!

CAUTION: There may be a dangerous situation and if not taken the right steps, can occur in serious injury or property damage. Work with extreme caution!

ATTENTION: There may be a dangerous situation and if not taken the right steps, can occur in serious injury or property damage.

1.4 BOILER OPERATION

ATTENTION: If entered the boiler room unauthorized persons, can occur in serious injury

or property damage. The system operator must ensure the boiler room for access by un-

authorized persons and especially children.

1.4.1 PROTECTIVE EQUIPMENT FOR BOILER OPERATION

By boiler operation, it is necessary to use protective equipment in accordance with established rules on safety at work. Extra care must be taken to protect the health by operation, cleaning and inspection of the boiler. It is necessary to wear gloves with increased heat resistance, suitable clothing and sturdy shoes.

1.5 FUEL

1.5.1 WOOD

The ATTACK DPX COMBI Pellet can be used soft and hard chopped firewood with a heat value 15 – 17 MJ/kg. Ideal are especially beech, oak, fir, spruce, pine, poplar, alder, willow, birch, ash, hornbeam, acacia, each with a moisture 12 – 20 %. A suitable diameter of the logs is 80 – 150 mm. The maximum length of the logs must not exceed 580 mm in order to prevent jamming of the logs in the loading chamber.

Heat value of different type of wood:

Wood Kcal/kg

Spruce 3 900 16,25 4,5 Pine 3 800 15,80 4,4 Birch 3 750 15,50 4,3 Oak 3 600 15,10 4,2 Beech 3 450 14,40 4,0

ATTENTION: Wrong moisture or size of wood can be reduced or increased output, low or high temperature of flue gas, excessive condensation, loss of flame by gasification or

uncontrollable combustion.

Units

kWh/kg

Recommended storage and drying of wood:

Hard wood: 2 years stored in a dry place Soft wood: 1 year stored in a dry place

Wood during storage (drying) must be protected against rain. Effective drying of wood can help,that the wood will be saved with the largest possible air gaps. Then air can flow between the pieces of wood. When drying there are places where wind operates for wood. It helps in faster drying of wood. If it is possible, before loading of wood into the boiler, keep it at least one day in a warm place such as a boiler room (this increases the combustion efficiency).

1.5.2 PELLETS

In the boiler can be used only pressed wood pellets without additional materials and the following parameters:

Specification of pellets:

Specific weight: 600 – 750 kg/m Heat value: 4,7 – 5,0 kWh/kg Size/diameter: 6 mm Size/length: Max. 35 mm! Moisture max.: 12 % Ash content: 0,5 – 1 % Dust content: max. 3 % Ash fusion temperature: min. 1 100 °C Standards: DIN 51 731 – HP 5, DIN Plus, or EN 14961–2 – A1

1.5.3 ALTERNATIVE FUELS

In the boiler can be also used wood briquettes with a hole, pressed from wood dust without additional connecting materials. Wood briquettes must always be mixed in a certain ratio together with the log (the ratio depends on the size and shape of the briquettes) to prevent stoppage of the nozzle for the gasification of wood.

ATTENTION: Illegal type of fuel increase demand for cleaning and lead to the accumula-

tion of aggressive sedimentation and condensation, which at the end can lead to reduced functionality, boiler damage and void warranty. The use of illegal fuel can cause wrong and uncontrolled combustion.

2 ASSEMBLY AND INSTALLATION OF THE BOILER

2.1 MANIPULATION WITH THE BOILER

The boiler is delivered on pallet. Manipulation with the boiler always perform on the pallet. Only if is boiler on installation place, remove the boiler from the pallet. This can be done with the help of a handling truck or a crane and hanging ears, which are welded to the heat exchanger of the boiler.

2.3 PLACING THE BOILER

The boiler is intended to be installed and operated in the premises with the basic environment (AA5/AB5) following the STN 33 2000–1:2009–04.

Boiler room must meet also the following conditions:

• The boiler room must not be potentially explosive environments, due to the fact that the

boiler is not suitable for use in such environments.

• The temperature in the boiler room must not fall below freezing point.

• Boiler provides no lighting. The customer must ensure sufficient light source according to

local standards and regulations.

• If the boiler will be installed at altitudes over 1 800 m, it is necessary to consulted this instal-

lation with the producer.

• The boiler room must be secured with a hole for good air circulation and also required inlet

for combustion air, but at least 200 cm2. The hole should be designed so that external weather does not affect its function (rain, snow, wind).

By the boiler installation it is necessary to keep the safety distance of its surface from flammable materials according to their degree of flammability:

• from materials of the flammability degree B, C1 and C2 200 mm

• from materials of the flammability degree C3 400 mm

• from materials of the flammability degree not approved 400 mm

Examples of classification of the building materials by their degree of flammability:

• degree of flammability A inflammable (bricks, blocks, ceramic tiles, mortar, parging)

• degree of flammability B partly flammable (heraklith, lignos, board from basalt felt, novodur)

• degree of flammability C1 difficult to ignite (hardwood (oak, beech), plywood, werzalit, hardened paper)

• degree of flammability C2 normal combustibility (softwood (pine, spruce), chipboard, solodur)

• degree of flammability C3 easily ignited (wood fibre boards, polyurethane, PVC, foam rubber, polystyrene)

The sealing board or protection covering (on the protected item) must exceed the boiler edge for at least 300 mm. Also other items from flammable materials must be protected in this way, if they are placed near the boiler and it is not possible to keep the safe distance. If the boiler stands on a flammable surface, it must be protected by an inflammable, heat insulating mat, which exceeds the edge on the side of the feeding door and the ash tray door for at least 100 mm. All materials of the A flammability degree can be used as an inflammable, heat insulating mat. The boiler must be placed in a such way ensuring sufficient space of at least 1 m from the front and 0,5 m from the left (right) and rear side. It is necessary to leave the space of at least 1 m above the boiler. This space is necessary for basic operation, maintenance and eventual service of the boiler. It is not allowed to place the boiler in dwelling premises (including corridors). There must be an opening for the air inlet for burning of at least 200 cm2 depending on the boiler output.

ATTENETION: The items from flammable materials must not be laid on the boiler and in the distance shorter than the permitted (safe) one.

The boiler must be turned off, if there is a danger of fire or explosion due to the work (e.g. work with painting materials, glues, etc.).

It is not allowed to place the boiler in residential premises (including corridors)!

2.4 BOILER CONNECTION TO THE HEATING SYSTEM

Boiler ATTACK DPX COMBI Pellet must be installed in system complying with the quality of heating water as follows:

Slovak Republic: STN 07 7401:1991 Austria: ONORM H5195–1 Germany: VDI 2035 Switzerland: SWKI 97–1 Italy: D.P.R. no. 412

Before installing the boiler, it is necessary to flush (to clean) the whole heating system. The system can be filled only the water treated to the values under the STN 07 7401: 1992. The water has to be clear, colorless, free of suspended substances, oil and chemically aggressive impurities and must not be acidic (pH must be higher than 7,2).

Callosity of the water must not excess 1 mmol/l and concentration of the Ca²Ѐ must be lower than 0,3 mmol/l.

ATTENTION: If these conditions are not kept, the warranty is not valid!

2.4.1 ANTIFREEZER USING

It is not recommended to use antifreezer because of their unsuitable properties for the boiler. In particular, the reduction in heat transfer, large volume expansion, aging, damage rubber components. In urgent cases, it is possible to use antifreezer Alycol Term (manufacturer Slovnaft Bratislava) – according to the experience of the manufacturer, it could not be a decrease in the safety of use and significant effects on the boiler. Unless the specific conditions this method of frost protection heating system feasible, non–performance functional parameters or any defects in the boiler due to the use of other antifreezer, can not be addressed under warranty.

2.4.2 BOILER PROTECTION AGAINST CORROSSION

Use of the mixing device (Regumat ATTACK–OVENTROP) is a suitable solution of the problem with corrosion. It enables creation of the separate boiler and heating circuit. Thereby is the boiler protected against undercooling below 65 °C and the creation of water steams, acids and tars in the boiler´s feeding chamber is eliminated. The Regumat ATTACK–OVENTROP device keeps the constant temperature of the return heating water flowing into the boiler over 65 °C by setting the thermostatic head to the level 5 – 6. When the individual thermal regulation mixing valve is used, it is possible to control the temperature of the heating water independently on the temperature of water in the boiler by setting the flap. The temperature in the boiler has to be kept in the range of 80 – 90 °C.

ATTACK–OVENTROP

ATTENTION: If is not installed in the system equipment against condensation, or the

equipment will not operate properly, can result in the formation of aggressive conden-

sate. It lead to boiler damage. Protection against condensation must be used during

operation of the boiler, otherwise it will void warranty by the manufacturer!

2.4.3 CHIMNEY

Connection of the appliance to the chimney hole must be always done with permission of the appropriate chimney sweep association. The chimney must generate sufficient draught and take the flue gas out into the atmosphere under the all operating conditions. Correct dimensions of the chimney hole are important the correct boiler function, because the burning, output and boiler life–time are influenced by the draught. The chimney draught directly depends on its diameter, height and roughness of the internal wall. It is not allowed to connect any other appliance to the chimney, where the boiler is connected. Diameter of the chimney must not be smaller than the connection part on the boiler. The chimney draught must achieve the prescribed values, but it cannot be too high, not to decrease the boiler output and interrupt the burning (flame). If there is too strong draught, install the throttle flap into the chimney hole between the boiler and the chimney.

Prescribed dimensions of the chimney section:

20×20 cm min. height 7 m ∅ 20 cm min. height 8 m 15×15 cm min. height 11 m ∅ 16 cm min. height 12 m

The exact chimney dimension is defined by the STN 73 42 10. The prescribed chimney draught is given in the Technical parameters.

2.4.4 FLUE GAS CONNECTION

The flue connection must lead into the chimney hole. If it is not possible to connect the boiler to the chimney hole directly, then the appropriate extension should be as short as possible, of up to 1 m length, without any additional heating area and it should ascend in direction to the chimney. The flue connection must be mechanically tight (it should be mounted to the boiler and tightly fixed by screws) and tight against the flue leakage. The flue connections must to lead through the foreign dwelling or commercial premises. The internal diameter of the flue connection must not taper in direction to the chimney. It is not suitable to use the elbow connectors. Flue must be connected to a chimney T–shaped to drop condensate from the chimney into an aimed container and not to the boiler.

2.4.5 BOILER CONNECTION TO THE ELECTRICITY MAINS

The boiler is connected to the electricity mains of 230 V/50 Hz/16 A by an electrical cord with plug. In the case of need, the power supply cord of the M type must be replaced with an adequate one by the service organization. The appliance must be placed in the way enabling to reach the connection plug. The boiler must be connected to the 16 A socket circuit by a circuit breaker (following the STN EN 60 335–1 + A11:1997).

2.4.6 CONNECTION WITH EXTERNAL PELLET TANK AND PELLET FEEDER

To the boiler ATTACK DPX COMBI Pellet is recommend to use ATTACK pellet tank in combination with screwed ATTACK pellet feeder, length about 2 m. Pellet tank is possible to place on the

right or the left side of the boiler, where necessary. For 30 kW burner there is recommended PED200 feeder. Feeder PED210 is recommended for 50 kW burner. Between hole of

feeder and delivery tube on the burner should be a height difference at least 300 mm. In the horizontal direction should be space between the hole of feeder and delivery tube at least 150 mm (i.e. not vertically aligned). Before first starting up of the burner it is necessary to make setting of feeder (p. 58). For setting of the feeder it is necessary to load the pellet tank with sufficient amount of pellets and load the pellet feeder with connection to the mains until the pellets begin falling down of the top hole of the feeder. Connect the feeder to the burner outlet. After correct setting of the feeder, install the inlet hose between the outlet tube of feeder and the delivery tube of burner and adjust the length of the hose. The hose should not be straight and also not so bented to prevent the pellets inside of stacking and accumulating.

2.4.7 BURNER CONNECTION TO THE BOILER AND BOILER TEMPERATURE

SENSOR

Burner is connected to the boiler by cable with 6–pin connector that comes from the feet of the boiler, at the point where pantograph arm is fixed. The cable is necessary after assembly to attach to the arm of the pantograph by supplied plastic tapes from the bottom of the pantograph arms in a correct distance so by manipulation of the burner to prevent stretching or strain of the cable. With the cable is also connected the boiler temperature sensor to the arm of the pantograph. The connector which is the sensor completed, it is necessary to connect in connector TS2 in control electronic of burner.

2.4.8 CHOICE AND CONNECTION OF THE CONTROL AND REGULATION COM-

PONENTS

The boiler is delivered with the basic regulation and control equipment. These should be supplemented by elements that are not part of the boiler delivery but must be installed in the heating circuit. They are mainly a safety valve (picture 4) against exceeding the allowable pressure in the heating system (priecribe 2.5 bar), the valve of aftercooling circuit of the boiler to abduce surplus heat from the boiler to the drain and vent valve for proper operation of the boiler. The expansion tank in the system must have sufficient volume to be fixed by designer of heating system under current regulations. Electric installation with the additional equipment of the boiler must be done by a specialist according to the current standards.

WARNING! The heating system must be equipped with

a safety valve against overpressure (2,5 bar). This valve is recommended to place on riser in front of shut–off valve of the boiler (or before OVENTROP). If the safety valve will not be working, excess

pressure have nowhere to escape and the boiler may explode!

Safety valve against overpressure

2.4.9 BOILER PROTECTION AGAINST OVERHEATING

Each gasification boiler must be equipped with functional cooling circuit. The right valve to provide the feature can be ordered as an accessory. The correct installation of the cooling circuit valve can be seen in pic. on the right.

WARNING! Following the norm EN 303–5, the

aftercooling circuit against the boiler overheat-

ing must not be used for other purposes than boiler protection against overheating.

The valve at the cold water inlet into the cooling loop must be permanently open and the cooling loop of the boiler must be connected to the functional cold water distribution (e.g. to the cold water supply into the water distribution network) with the temperature of 10 – 15 °C and the operating overpressure of 2 – 6 bar. This valve also ensure safe operation even in power cut. The STS20 valve at outlet of the cooling loop with the sensor placed in the rear part of the boiler protects the boiler in the following way. When the temperature of water in the boiler exceeds 95 °C, then the water from the distribution network flows into the cooling loop to absorb the surplus heat. In the case of boiler overheating and opening the STS20 valve it is necessary to ensure the permanent outtake of the warmed water from the boiler aftercooling circuit into the drain. Functionality of aftercooling circuit and thermostatic valve can be tested each time manually, with the manual button of the thermostatic valve.

WARNING! If the outtake of cooling water through the cooling loop is not ensured

after opening the STS20 valve, there is a danger of boiler damage! In this case is the

warranty for the boiler not valid!

2.4.10 CONNECTION TO THE ACCUMULATION TANKS

Connection system consists in heating of accumulation tanks heat. Accumulated heat of the accumulation tanks is gradually taken according to requirements into heated space. When is the boiler operating at full output, the storage tanks are heated to 80 – 90 °C. Heating with accumulation tanks in connection with the boiler ATTACK DPX COMBI Pellet brings several advantages. Highlights include the longer boiler life, cleaner operation and minimal creation of acid and condensate, less frequently of fuel loading, higher comfort, less possibility of overheating of the boiler and lower fuel consumption. Recommended capacity of accumulation tank for boiler ATTACK DPX COMBI Pellet is 50 l per 1 kW boiler output, the minimum capacity is 25 l per 1 kW boiler output. When choosing a capacity of accumulation tank, it is necessary to have on mind that the size of the accumulation tank affects on operation of the boiler. That means, we load the boiler regarding to the size of accumulation tank to prevent overheating of the system. Therefore is very important to have on mind that the boiler needs to be load always just with enough wood, to heat up the accumulation tank, but not overheat. There may be to remove the surplus heat to waste. This is uneconomical and requires activation of safety element – aftercooling circuit.

TUV

The bigger volume of the accumulation tank, the less risk of overheating. With the larger capacity of the accumulation tank is the loading time shorter.

Note: It should be noted that the above is only relevant in the operation of boiler with WOOD.

In operation of PELLETS it loses meaning, the boiler need not be connected to the accumulation tank, but the boiler have to operate always only with PELLETS.

5 PURPOSE OF USE

The ecological warm water boiler ATTACK DPX is intended for heating the family houses and other similar objects. The boiler is designed only for the use of wood logs. Any type of dry wood can be used, especially the wood logs. It is also possible to use the blocks of wood with larger diameter – then is the boiler output lower, but the time of burning is longer. The boiler is not suitable to burn the saw dust and small wooden waste. Only small amount (approximately 10 %) of such a material can be used together with the wood logs. Thanks to the voluminous feeding chamber it is not necessary to do the most demanding work with wood – chopping into smaller pieces.

WARNING! It is not allowed to operate with the boiler on both fuels at the same

time. It is never allowed to heat with wood until the burner is in upper loading door of boiler and also is not allowed to heat with pellets if the wood is in loading chamber of boiler! It is also not allowed to use the pellet burner to ignite the wood. During the boiler operation with wood, it is always necessary to use the upper door cover!

6 TECHNICAL DESCRIPTION

The boiler is designed to burn wood on principle of the wood gasification by using the exhaust fan that sucks the flue gas from the boiler. In automatic pellet mode when is inserted the pellet burner in the upper door, the boiler heat on wood pellets, which burn in the combustion chamber of the burner. Transport of pellets ensure the external pellet feeder from the external tank. It is not allowed to operate with the boiler on both fuels at the same time. The boiler body is welded from the steel plates of 3 – 6 mm thickness. In the feeding chamber there is a fireproof nozzle with longitudinal opening for the flue gas and gas passage. In the burning chamber there is a fireproof ashtray. In the rear part of the boiler body is the tubular exchanger with the flue gas collector and the heat up flap in the upper part. In the front parts there is a feeding door and at the bottom there is the ashtray door. Between the doors there are the primary and secondary air inlets placed under the boiler covering. In the left covering at the same level as the middle of the feeding door there is a pull rod of the heat up flap that is controlled by the feeding door and there is also the lever for exchanger cleaning. The boiler body is insulated by a mineral wool, inserted under the external covering. The control panel for electromechanical regulation is placed in the upper part of the boiler (operation with wood).

On the right side to the heat exchanger is mounted the holder of console for pantograph system for holding the burner. On the console are pins which attached two arms of the pantograph, with burner door and the burner. ATTACK PELLET BURNER Automatic 8 – 30 kW or 15 – 50 kW works on basis of the fuel feeding by the principle of falling, when the pellets fall by from the pellet feeder through the inlet hose and the inlet tube on the grate, where they are burned. The burner has an electrical ignition that automatically lights the pellets fallen on the grate. It is equipped with a self–cleaning mechanism of the grate.

ATTACK PELLET BURNER Automatic 8 – 30 kW consists of combustion chamber from 3 mm heat– resistant stainless steel, air chamber with fan and units for self cleaning mechanism of the grate.

Base of ATTACK PELLET BURNER Automatic 15 – 50 kW combustion chamber consists of combustion chamber from 4 mm heat–resistant stainless steel, air chamber, grate for pellet burning, control units and self cleaning of the grate.

6.1 TECHNICAL DESCRIPTION OF ATTACK DPX COMBI PELLET

6.1.1 OPERATING PRESCRIPTIONS

Boiler preparation for operation

Before starting the boiler, it is necessary to check that the system is filled with water, deaerated and the pressure of heating water does not decrease. Make sure that the sensors of the boiler, safety thermostat and manometer are placed in casings on the upper rear side of the boiler. Check the tightness and construction of the flue connection. The boiler has to be operated in line with the instructions given in this manual to achieve its good service. By boiler installation you can underlay it for 10 mm to enable better flush by water and deaeration. Only an adult trained person with completed elementary education can operate the boiler.

ATTENTION: By the first heat up it may come to condensation and leakage of the con-

densate – it is not a fault. There will be no more condensate after heating for a longer

time. In the case that the smaller wooden waste is being burned, it is necessary to check the flue gas temperature which should not exceed 320 °C. Otherwise it could damage the fan. By the gasification of wood it is normal that tar and condensates are created.

If the boiler has been out of order for a longer period, it is necessary to be more careful by starting it again. It could come to the pump blockage, leakage of water from the system or to the boiler freezing in the winter.

6.1.2 HEATING UP AND OPERATION

Before igniting the fuel, open the feeding door and push the pull rod of the heat up flap back to the basic position until is the latch fixed (like when the door is closed, see the picture).

Position after the feeding door is open

Press backwards and downwards

Position after pressing backwards and downwards

ATTENTION: The pull rod of the heat up flap has to be pushed backwards to close

the heat up flap. Otherwise the fan could get damaged!

For wood gasification in the boiler it is necessary to keep the reduction layer during the operation (the layer of wood coal on the nozzle in the feeding chamber). Therefore it is necessary to burn dry wood of a suitable size. When the wet wood is burned, the boiler does not work as a wood gasifying boiler, the wood consumption rises, the output is not sufficient and service life of the boiler and of the chimney is shortened. When there is a prescribed chimney draught, the boiler works up to 70 % of its output even without the fan.

Refilling the fuel

When refilling the fuel, open the feeding door. The heat up flap is opened at the same time. Do not stop the fan. Always keep the feeding chamber full when heating up. Not to let the smoke flow into the boiler room, refill the fuel after it is burned to approximately 1/3 of the feeding chamber. Cover the glowing coal with a wide wood log and refill the fuel normally. Do not press the fuel on the nozzle, otherwise it could get clogged and the parameters of burning would be worse.

7 OPERATION OF BOILER ATTACK DPX COMBI PELLET

The PROFI PID electronics is located on the front side of the control panel, where the main boiler switch is located. In the pictures below you can see the basic and safety features of the control panel.

1. Electronic regulator PROFI

2. Manometer

3. Safety thermostat

4. MODE switch

The safety thermostat is placed on the rear side of the control board.

Under the PROFI PID electronics there is a WOOD / PELLET mode switch.

Operation in mode WOOD: The switch will switch to WOOD and the display will show the current boiler temperature, the controller will be in standby mode.

WARNING: In case the fan is switched on by the START button on the PROFI electronics and the burner is connected in the boiler, there will be displayed failure of fan turns on

burner.

Operation in mode PELLETS:

The switch switches to the PELLET position and P (see chapter 7.5 Operating modes) is displayed behind the current boiler temperature value on the PROFI electronics display. In this mode, the PROFI electronics will not allow you to switch on the exhaust fan by pressing the START button. The operation of the boiler exhaust fan will be controlled by the burner electronics, depending on the burner fan operation.

7.1 OPERATION OF BOILER ATTACK DPX COMBI PELLET – WOOD

MODE

Boiler regulation – wood mode provides high comfort, the possibility of output modulation and connection to control and regulation units. The boiler temperature is at the level set by the enduser, to control the flue gas fan rotations. ATTACK boiler regulator measures the temperature of the water in the boiler all the time and the value shows on the display with improved controller for flue gas temperature by PID. Based on this value, the controller controls the fan rotations and pump of central heating.

Technical description of ATTACK PROFI boiler:

Connection

Before turning–on the boiler with the main switcher, connect the controller, fan, circulation pump and power cords into the appropriate sockets at the rear part of boiler. Boiler temperature sensor must be placed in the boiler basin. Set the switch to position WOOD.

WARNING! Before connecting the controller to the mains, check that it is properly grounded and the terminal screws are tightened properly.

ATTENTION: Maximum total output of units connected to the controller can not exceed 700 W.

ATTENTION: For extended function of controller can be connected the module UM–1, which allows to control start–up of another automatic boiler.

7.2 ADVANTAGES OF THE REGULATOR

The regulator can control:

1. Rotations of flue gas fan

2. Circuit pump of heating circuits

3. Pump for warming the D.H.W. or pump for warming the accumulation tank (always just one)

4. Starting another, automatic boiler, if the fuel in the boiler burned out

The regulator measures the following:

1. Boiler temperature

2. Flue gas temperature

3. Temperature in the D.H.W. tank or in the accumulation tank (always just one)

4. Room thermostat and thereby it controls the circuit pump

7.3 BASIC DESCRIPTION OF THE REGULATOR

7.4 CONNECTION OF THE REGULATOR BY HYDRAULIC SCHEMES

The regulator can control several types of hydraulic schemes. Parameters in the service menu must be correctly set adequately to the type of the hydraulic scheme.

* Schemes shows the connection to the pumps and sensors. On the schemes is not showing the connection to the fan and mains.

Scheme A: Wood gasifying boiler + heating circuit

Parameter setting for the hydraulic scheme A:

ur = ur0

Scheme B: Wood gasifying boiler + heating circuit + warming of D.H.W.

Parameter setting for the hydraulic scheme B:

ur = ur1 – for priority charging of the D.H.W. tank ur = ur2 – for paralel charging the D.H.W. tank

Scheme C: Wood gasifying boiler + heating circuit + warming of accumulation tank

Parameter setting for the hydraulic scheme C:

ur = ur4

Scheme D: Wood gasifying boiler + heating circuit + warming of accumulation tanks connected in serie

Parameter setting for the hydraulic scheme D:

ur = ur4

Scheme E: Wood gasifying boiler + heating circuit + warming of combined accumulation tank

Parameter setting for the hydraulic scheme E:

ur = ur4

7.5 REGULATOR CONTROL AND OPERATING MODES

Turning on the controller is signalized by a brief switching on all the light indicators on display to enable to check their status. If the regulator gets suddenly disconnected from electricity mains (e.g. by power failure), it is switched to the last mode used, when the failure occurred. All the settings made are saved even after the power failure.

The basic setting of the controller is the adjustment of the boiler temperature by the knob. Other functions are controlled adequately to the service parameters set in the service menu.

The boiler is turned on by pressing the START (17) button that starts the fan. The STOP (16) button switches the boiler off by turning the fan off.

The sign displayed behind the numeric temperature indication (7) is related to the current mode of the PID PROFI regulator:

[50°-] indicates the stand–by mode [50 °C] indicates the winter operating mode [50 °C] indicates the winter operating mode when the boiler temperature is achieved [50°U] indicates summer operating mode intended only for D.H.W. preparation [50°u] indicates summer operating mode when the boiler temperature is achieved [70°d] indicates mode of elimination the legionella bacteria, when the temperature of D.H.W. is

increased to 75 °C

[50°P] indicates that regulator is blocked by pellet burner of the COMBI Pellet boiler

The PROFI PID regulator has an advantage of regulating the flue gas temperature to the required value. The controller struggles to achieve the adjusted flue gas temperature and after it is achieved, the required boiler temperature is to be reached. Thereby is the fuel used in the best way and the high efficiency is achieved.

7.6 SETTING THE USER PARAMETERS

The menu for displaying and setting the user parameters is accessible after short pressing of the OK button. The „+“ and „−“ buttons are used to browse in settings and parameters. The appropriate parameter selected becomes adjustable by the „OK“ button and starts to flicker. Then it can be changed by the „+“ and „−“ button and confirmed by „OK“.

The summer mode is indicated by the „–“ sign. Then is the circuit pump out of order and the heat generated by boiler is only used to heat the D.H.W. tank. If there is not D.H.W. tank in the system (additional sensor is not connected), it is not possible to select the SUMMER / WINTER mode.

[cu u] – Mode of D.H.W. tank warming – the regulator enables the casual D.H.W. tank warming „u“ or the mode to eliminate the legionella bacteria „d“. After the „d“ mode is selected, the temperature of 75 °C is achieved in the D.H.W. tank. When this temperature is achieved, the controller switches into the mode of the casual D.H.W. tank warming „u“. The option of elimination the legionella bacteria is not available, if the additional outlet and sensor are not set for the D.H.W. warming.

ATTENTION! Not to get hurt by the hot water, it is recommended to set this mode, when the D.H.W. is not being used (e.g. during the night).

7.8 DESCRIPTION OF PARAMETERS

[Π100] Maximum fan output – the highest fan output possible

[n 40] Minimum fan output – the lowest fan output possible

[Πh 5] Ratio of changing the fan rotations – this parameter influences the fan rotations, if the

adjusted boiler temperature is going to be achieved in a short time. For example, if the value 4 is set, the fan will work at full output [Π100] (if the function of flue gas temperature control is not active), up to 4 degrees before achieving the required boiler temperature. Then, by every increase of the boiler temperature for 1 °C, the fan rotations are gradually decreased until the minimum fan output is reached [n 40].

[Πr 0] Automatic regulation of changing the fan rotations – the fan rotations are increased / decreased by setting this parameter within the range of 0 – 10 to ensure the required boiler temperature. If this parameter is set to „– –“, the rotations are not controlled and the fan works at full output according to the parameter [Π100]. Setting the parameter within the range of 0 – 10 relates to the time period (in minutes), during which are the fan rotations gradually increased from the parameter of the minimum fan rotations [n 40] up to the parameter [r 100]. This ensures the fluent heat–up of boiler.

[Πn 5] Frequency of exhaust fan blow–through – this frequency defines, how often the fan is started to the full output [Π100] to take the flue gas out from the boiler, if the fan was stopped due to the boiler temperature achieved.

[Πu 6] Duration of exhaust fan blow–through – during this period must the fan exhaust the flue gas following the parameter [Πn 5].

[r 100] Fan output by ignition – this parameter defines the fan output by boiler heat–up. If the parameter " Πr " is set to [Πr 0], then this parameter is not available.

[rh 5] Hysteresis of boiler stop by ignition – defines, how many degrees before reaching the required boiler temperature will be the heat–up phase finished or (if the flue gas temperature sensor is connected), how many degrees before reaching the required flue gas temperature are relevant to stop the heat–up phase. After deactivation of the heat–up phase there is a casual operating mode.

[P 30] Temperature to start the circuit pump – if there is not D.H.W. tank in the system [ur 0] or it is in the mode [ur 2], then the parameter defines the boiler temperature for starting the circuit pump of the heating system. If the parameter is set to „– –“, then too low temperature does not influence the operation of the circuit pump. Anyway, the pump is always started, when the boiler temperature exceeds the parameter [H 85] of the maximum boiler temperature.

If there is accumulation tank in the system (parameter [ur 4]), then this parameter defines the temperature measured in the accumulation tank by which is the circuit pump of the heating system started.

[Ph 2] Hysteresis of circuit pump – defines the temperature difference under which must the boiler temperature or temperature in the accumulation tank decrease in comparison with the temperature defined by the parameter [P 30] to stop the circuit pump.

[Pc ––] Interval of unlock function of circuit pump –when controller is in the stand–by mode or the room thermostat is disconnected, the circuit pump is started for 30 seconds after each [Pc ––] minutes to prevent the pump blockage caused by its inactivity. The unlock pump function is not active, when the Pc is set to „– –“.

[ur 0] Operation of the additional output – this parameter defines the operating mode of the

additional output (pump for D.H.W. tank or accumulation tank warming).

[ur 0] Additional output without function – defines that the additional output and pump are not connected and the additional output is not used in this case.

[ur 1] Priority D.H.W. tank warming – by this setting is the pump for D.H.W. tank warming connected to the additional output and the sensor of D.H.W. is connected to the additional inlet. Then, if the temperature in the D.H.W. tank decreases under the value of hysteresis [uh 5] from the temperature adjusted [u 60], the pump of D.H.W. tank warming is started. After the temperature in the D.H.W. tank reaches the set value [u 60], the pump is stopped. The pump is also stopped, when the temperature in boiler is lower than the temperature in D.H.W. tank. The [ur 1] mode means that the D.H.W. warming has priority, i.e. the pump of the heating circuit is started after the D.H.W. is prepared.

[ur 2] Parallel charging the D.H.W. tank – similar principle as by the [ur 1], just the D.H.W. is prepared by the parallel operation of the circuit pump of the heating circuit.

[ur 3] Unused

[ur 4] Charging the accumulation tank – due to this setting is the additional output used as

a pump to heat the accumulation tank and the additional sensor measures its temperature. When the temperature in the boiler exceeds the hysteresis [uh 5] over the current temperature of accumulation tank, the pump for charging is started. The pump is stopped, when the temperature in the boiler is same or lower than the temperature in the accumulation tank, or when the temperature in boiler decreases under the minimum boiler temperature defined by the parameter [L 65].

[u 30] Operating temperature of the D.H.W. tank or accumulation tank – temperature to control the additional output [ur ].

[uh 5] Hysteresis of the D.H.W. tank or accumulation – this parameter defines hysteresis of the additional output [ur ].

[uP 5] Boiler temperature increase by D.H.W. preparation – this parameter is relevant, when the additional output works under the mode of D.H.W. tank charging. It defines, for how many degrees will the adjusted boiler temperature be higher than parameter [u 50] during the D.H.W. tank warming.

[L 65] Minimum boiler temperature – defines the minimum boiler temperature that can be set by a knob.

[H 85] Maximum boiler temperature – defines the maximum boiler temperature that can be set by a knob.

[h 2] Hysteresis of boiler temperature – defines the difference between the adjusted and the current boiler temperature for which must the boiler temperature decrease to start the controller again after the adjusted boiler temperature is achieved.

[A 99] Temperature of boiler overheating – defines the value of boiler temperature to activate the alarm of the boiler overheating.

[Fd60] Duration of boiler stop by ignition and fuel shortage – this parameter defines the maximum time between starting the controller by the START button and achieving the control-

ler´s operating mode (reaching the flue gas temperature of [c 90]). If the temperature of [c 90] is not reached during the heating up, the fan is stopped and the alarm FUEL (fuel shortage) is displayed.

[Fb30] Duration of boiler stop by flue shortage and burn–down – the fuel amount test is activated in the operating mode, when the flue gas temperature decreases under the parameter [c 90] or (if the flue gas sensor is not connected) when the boiler temperature decreases under the adjusted parameter [L 45]. If the temperature does not exceed the necessary limit during this period, the controller displays FUEL alarm.

[Ar 0] Operation of multifunction additional output – the controller is equipped with an additional multifunctional outputs compatible with the options listed below (to control these options is necessary to use an additional module UM – 1):

• [Ar 0] parameter – indicates start of the automatic boiler (e.g. gas or pellet boiler). When the controller is started and the boiler generates heat, the automatic boiler is stopped. Operation of the automatic boiler is blocked by the controller in the operating mode. The automatic boiler is started by controller, when the fuel is burned down in the boiler and the FUEL alarm is displayed.

• [Ar 1] parameter – indicates that the additional multifunctional output will be used for error messages like boiler sensor failure, overheating or fuel shortage.

[c 240] Adjusted flue gas temperature – the controller will struggle to reach and to keep this value. The flue gas temperature sensor is turned off, if this parameter is set to „– –“.

[c h5] Hysteresis of flue gas temperature – defines the difference for which must the flue gas temperature decrease to increase the fan rotations.

[c t 5] Time constant of stabilization the flue gas temperature – defines the period of adjusting the fan rotations during stabilization of the flue gas temperature. If the flue gas temperature exceeds the value given by the parameter [c 240], the controller starts to decrease the fan rotations gradually, until the flue gas temperature decreases to the adjusted value. If the flue gas temperature decreases to the value of flue gas temperature hysteresis, the controller starts to increase the fan rotations gradually.

[c F10] Blower speed jump while stabilizing exhaust gas temperature – defines the change of rotations to achieve the adjusted flue gas temperature.

[c 90] Flue gas temperature by fuel shortage – the message „FUEL“ for fuel shortage is displayed after the flue gas temperature decreases under this value.

Testing the regulator outputs:

It is possible to make a check to test the correct functionality of the regulator and devices connected. The correct function of fan is tested by selecting the [outΠ] on display and holding the „OK“ button. Test of the circuit pump is done by selecting the [outP]. Select the [outu] to start the additional output and [outr] for multifunctional additional output.

Reset of the regulator´s pruduction settings:

There is a possibility to reset the production settings of the regulator by selecting the [Prod] in the service menu and confirming by „OK“ button. Then is the regulator set to the values given in the Table 3.

Exit from service menu:

Select the [End] on display and press the „OK“ button to exit from service menu.

7.9 ERROR MESSAGES

The connection of all sensors of the regulator is permanently monitored. If the regulator detects that some of the sensors is not connected, the error messages are displayed. Messages about the boiler overheating or fuel shortage are also displayed.

7.9.1 ERROR MESSAGES DISPLAYED

[FUEL] – is displayed, when there is not enough fuel in the boiler. The sufficient amount of fuel is

defined by the parameter c90, where the figure 90 is related to the adjusted value 90 °C. Then, if the flue gas temperature decreases under this adjusted value within the time Fb30 (time of boiler stop by fuel shortage), the regulator displays the [FUEL] message. To start the boiler again, it is necessary to remove the message by the STOP button and then to press the START.

[HOT] – is displayed, when the flue gas temperature exceeds the maximum permitted value set by the parameter c300 (means 300 °C). The ventilator is stopped in this case. After the temperature decreases under the adjusted flue gas temperature, the ventilator is started again.

[E 1] – is displayed, when the boiler temperature sensor fails or when it is not connected. In such case is the regulator taking actions to ensure the safety of the boiler – the fan is stopped (if it is currently in operation) and the circuit pump is started for eventual safe boiler cooling. After the cause of error is removed, the error message can be erased by the STOP button.

[E 2] – is displayed, when the boiler temperature exceeds the boiler overheating temperature A99. The regulator stops the flue gas fan and starts the circuit pump. The error message can be removed by the STOP button after the boiler temperature decreases to the safe value.

[E 8] – is displayed, when the additional sensor fails (in the D.H.W. tank or accumulation tank). If this sensor works for the D.H.W. tank, the warming is blocked. If the sensor works for the accumulation tank, the pump will be permanently working. This error message cannot be removed by the STOP button. It is automatically erased after the sensor failure is repaired.

[E128] – is displayed, when the flue gas temperature sensor fails. In this case is the boiler control switched to regulate according to the boiler temperature. The error message is erased automatically after the fault of the flue gas temperature sensor is solved.

[E 3] If several failures occur in one moment, their total is displayed. In such case it is necessary to check the functionality of all sensors.

7.10 DISASSEMBLY OF THE REGULATOR

If it is necessary to disassemble the regulator, do the following:

• turn the main switch off

7.12 OUTPUT CONTROL OF ATTACK DPX COMBI PELLET

Adjustment of burning in the boiler

The burning is adjusted by the primary and secondary regulation flap. Producer sets the boilers to the optimum conditions of burning with reference to the emissions and flue gas temperature. Only the service staff trained by producer can make the adjustment.

Optimum setting of the regulation flaps – wood mode (Primary/Secondary):

DPX25CP – 50/40 DPX30CP – 50/25 DPX35CP – 50/50 DPX40CP – 100/60 DPX45CP – 100/60

7.13 OPERATION WITH PERMANENT BURNING

It is possible to keep the permanent burning, i.e. the fire in the boiler for the whole night without need to heat up during the day, but only in the winter period. This method of operation reduces the life of the boiler.

For the operation with permanent burning it is necessary to prepare the boiler in the following way:

• Lay some bigger wood logs (4 – 6 pcs.) on a glowing layer of fuel

• Close the mixing valve partly – temperature of water in the boiler achieves 80 – 90 °C

• The regulation flap controlled by thermal regulator is automatically closed and the fan is

stopped.

After the boiler is prepared in this way, the burning is kept for more than 12 hours. When the boiler is in the operation of permanent burning, the water temperature must be 80 – 90 °C.

8 BURNER ASSEMBLY TO THE BOILER

The boiler DPX COMBI Pellet – mode wood has mounted on the upper loading door cover – cover of the upper loading door. If you want to go for automatic pellet combustion, you have to remove this plug by simply movement up and down with the two handles and put it away from the boiler. After that it is necessary to mounted the pantograph, burner door and burner on the boiler.

Steps of burner assembly to the boiler:

1. For simple manipulation and operation during operation of the burner, the burner together with the burner door will be placed on the movable arms of pantograph. For their installation is necessary to mount the pantograph console in the hole in the right leg of boiler. Console will be fixed with four screws M12 × 20 with cylindric head and internal hexagonal screwdriver.

2. Then it is easy to put together arms of pantograph by pins, cotter and mats. By mounting the short arm of the pantograph is required to put bronze mat between the bottom of arm and

console, as well the mat on the bottom part of console. Pin is necessary to secure with the cotter.

3. The same process is applyed by installation of the long arm of the pantograph, where we put the bronze mat between short and long arm of pantograph, mat on the bottom part of short arm and pin is secured by cotter.

4. Burner door are supplied with console and pin, in one piece, for simple installation to the arm of the pantograph. Between the console door with pin and long pantograph arm put again bronze mat, other mat under the bottom part of the long arm and pin is secured by cotter.

5. Secure the burner door on movable arm to upper door of the boiler by simple movement of two handles. It is the same how it was by demounting of the plug.

6. Burner with flange pushed onto the welded screws on the burner door and secure with flat mat 8,4 and nuts M8.

7. Hanging cable for burner connection to the boiler to attach as well as the boiler temperature sensor to the arm of the pantograph by supplied plastic tapes from the bottom of the pantograph arms. Then put the cover on the burner.

9 OPERATION OF BOILER ATTACK DPX COMBI PELLET –

PELLETS MODE

Pellet burners ATTACK PELLET BURNER Automatic 8 – 30 kW and 15 – 50 kW built into the boiler, model ATTACK DPX COMBI Pellet 25, 30, 35, 40, 45, 50 are modern burners which are saving environment with combustion technology, offer to end users the advantage of low operating costs and offer also comfort comparable with the gas boilers when is boiler operating with pellets, automatic combustion. For the boiler operation with pellets is necessary to remove the plug of upper loading door. Block off two handles and put the plug away from the boiler. With the pantograph simply bring burner to the upper door of the boiler, insert it through the door into the boiler and block the burner with two handles. By blocking the burner to the door of the boiler, needs to make pressure in a straight line. The burner door needs to seal with the boiler door. Inserting and securing the burner in the boiler door, burner is ready for operation. On the control panel you must switch the mode switch to PELLETS position.

At the time when the burner is out of the boiler door it is not possible to operate or change the settings in the menu.

WARNING! After inserting the burner into the boiler DPX it is always necessary to

close the flaps of primary and secondary air. Otherwise the flue gas produce by the burner can exit through openings of primary and secondary air. This can be the cause of fire!

Setting of DPX boiler for wood combustion (primary and secondary flap open).

Setting of DPX boiler for pellets combustion (primary and secondary flap closed).

The burners ATTACK PELLET BURNER Automatic works on basis of the fuel feeding by the principle of falling, when the pellets fall by from the pellet feeder through the inlet hose and the inlet tube on the grate, where they are burned. The burners have an electrical ignition that automatically lights the pellets fallen on the grate. Starting the burner is controlled by adjusting the burner and boiler temperature or room thermostat, if it is connected. Start and stop temperature can be set in menu with buttons on the controll panel of the burner. Information about actual operation data is given on display. The burners have an own self–cleaning mechanism of the grate. When the thermostat reaches the adjusted off–temperature, the burn–out cycle begins and afterwards, the grate moves out to be cleaned by scraping. This enables longer time of use, without need to remove the burner from the boiler. Convectional parts of the boiler have to be cleaned in regular intervals to keep the high efficiency of heating.

The boiler can be used only moulded wood pellets without additional materials and with following parameters:

Approved fuel specification:

Measured weight: 600 – 750 kg/m Heat value: 4,7 – 5,0 kWh/kg Size/diameter: 6 mm Size/length: Attention! Max. 35 mm Moisture max.: 12 % Ash content: 0,5 – 1 % Dust content: max. 3 % Ash smoulder temperature: min. 1 100 °C Standards : DIN 51 731 – HP 5, DIN Plus, or EN 14961–2 – A1

Regulation of the pellet dosing

Before starting–up the burner, it is necessary to set the pellet supply through the parameter of the „Stoker Adj.“ in the Advanced menu. Thermostat cannot start the heating while the settings are being made. Firstly, set the parameter of the „heat value“ to the value given by your pellet supplier. If the supplier gives 4,8 kWh/kg, set the parameter to 48, etc. Now, put the plastic bag around the opening of the pellet feeder. Then, confirm by the „S“ button and keep the instructions. Weigh the pellets fallen into the plastic bag, put their weight in gramms via the „+/−“ buttons and press the „S“ to save the values. This setting has to be done within 15 minutes, otherwise the burner switches to the stand–by mode. Weigh the pellets very exactly! After setting of the above mentioned parameters, the control system automatically sets all the parameters relative to the pellet feeding.

9.4 DESCRIPTION OF FUNCTION

ATTENTION: The burner is controlled on the basis of the boiler temperature sensor (in

the burner menu must be set in the advanced settings THERMOSTAT to the "Combination") or room thermostat, if is connected to the terminals TP under the electrical scheme. It is possible to choose boiler temperature and hysteresis in burner menu. The burner will try to achieve the set temperature and according to hysteresis the burner will be turned on.

9.4.1 NORMAL START–UP IN STAND–BY MODE OF BURNER

When the thermostat gives instruction to the burner, the ventilator starts and the photocell controls the fire. If there is no fire, then comes the instruction to blow the burner through. Afterwards, pellets start to fall into the burner within the period stated by the control system and the ignition is activated. After the phase of fuel feeding for ignition is finished, the control system waits for signalization of fire from the photocell. When the photocell recognizes the fire, small amounts of pellets fall within the transition period. Duration of this depends on the output level set on the burner. Pellet supply is gradually increased, until the necessary fuel amount for the required output is achieved. This amount is further delivered into the burner, until the operation thermostat gives instruction to stop. This signal stops the pellet inlet, while ventilator continues to supply the air into the burner. When the photocell recognizes burn–out of pellets, the blow–through of the burner begins. According to the adjusted delay, the burner is cleaned after the fuel burns out – the grate moves out towards the scraper and the ash with the unburned elements falls through the front wall of the burner´s bottom into the ashpan. After the grate slides back, the burner waits for the new signal from thermostat.

CAUTION: : The unit for the grate moving is very strong and it might cause a threat. Nev-

er put any body parts or foreign articles into the burner, while it is working.

9.4.2 BURNER START–UP, WHEN THERE IS STILL FIRE IN THE BURNER

If the photocell recognizes the fire during the beginning phase (e.g. after the short time current shortage), the control system directly begins the transition–phase and the pellet burner continues to operate as by normal start. (see above)

9.4.3 BURNER START–UP, WHEN THE CONTROL SYSTEM DOES NOT RECOG-

NIZE THE FIRE

The normal start–up process follows, also when the control system does not receive the fire signal. The system starts shortly after repeated ignition process, which increases the ignition amount in the combustion chamber and heating of spiral continues until the photocell does not detect the presence of flame. These parameters are adjustable only by the trained person in service menu. If the second trial fails, all functions are turned off and the alarm is activated. This alarm is indicated on display.

For boilers, at which there is tough to achieve their draught, it is recommended to increase the time of test blow–through. From production it is set to 15 sec.

Setting of the transition period:

TRANS. PHASE

ENTER < > EXIT

There are two parameters of the transition phase: the first is 14 kW and the second is 30 kW. The time set by the first parameter determines, how long it will take to achieve 14 kW, time of the second parameter determines time to achieve 30 kW since the fire is recognized. The lower the required output is, the shorter is the period necessary to achieve it.

10 MAINTENANCE OF THE BOILER

During the boiler life is necessary to make maintenance to work properly. The maintenance frequency depends on boiler frequency and utilization when is boiler in operation process.

Maitenance of the heating system with the boiler

It is necessary to check, eventually to refill the water in the heating system at least 1× in 14 days. If the boiler is out of order during the winter period and danger the water could freeze in the heating system, then the water should be replaced with an antifreeze mixture approved by the producer or it should be discharged out of the system. Normally should be the water discharged only in urgent cases and for ash short time as possible. At the end of the heating season it is necessary to clean the boiler properly and to replace the damaged parts. Twice a year it is necessary to dismantle the fan, to clean the radial impeller and to clean the fan air chamber.

Adjusting the hinges and exchange of the sealing cord of the door

After a particular period is the sealing cord in the door pressed. To ensure its tightness is necessary to change the position of the door by screwing the door hinges. When the cord completely loses its elasticity, or the hinges can no longer be moved into the direction to the boiler, it must be replaced. Undo the worn sealing cord by the screw driver and clean the groove, where it was laid. Take the new sealing cord and put its ends into the horizontal parts of the groove. Use your hand, eventually a hammer to press the cord into the groove around the door. Loosen hinges and find the correct position of door hinges to the door.

Daily

Replacement of the nozzle

The nozzle is laid in the boiler body on the holder. In the bottom part is the nozzle sealed by a boiler sealant and in the upper part there is a sealing cord around. When replacing the nozzle, remove the sealing cord from the groove by a screw driver. Take the nozzle out and clean the holder properly from tar and old sealant. Then treat the bottom part of the nozzle with the fireproof sealant and put the nozzle on the clean holder with the arrow towards the rear boiler part. There should be the same space on the both sides of the nozzle. Take the new set of the sealing cords for the nozzle and press it lightly into the gap just around the nozzle.

10.1 BOILER CLEANING

The boiler must be cleaned regularly to operate correctly and reach the required comfort and durability.

ATTENTION: The boiler has to be cleaned regularly and properly, otherwise there is a risk

of its wrong functionality, shortened service life or damage! The warranty is not valid if the boiler is not regularly and sufficiently cleaned!

Cleaning the boiler should be carried out regularly and properly every 3 – 5 days because sedimentation in the loading and combustion chamber with condensation and tar significantly reduce the life, power and efficiency of the boiler. If is bigger amount of ash than is not enough space for burning out of fuel and this can damage the holder of ceramic jet as well as the whole boiler. By boiler cleaning at first turn on the fan, open the feeding door and wipe the ash through a slot into bottom space. Long pieces of unburned fuel leave in the hopper. Move sometimes with the exchanger cleaning lever on the left side of the boiler. Ash and smoke put out after opening the bottom cleaning hole. After opening the bottom door, clean the bottom space. Interval of cleaning depends on the quality of wood (moisture), heating intensity, chimney draft and other factors. We recommend to clean the boiler 1 time per week. Fireproof clay do not take out by cleaning. Check the cleaning channel of primary and secondary air or cleaned by scraping holes and blowing. It influences the output and quality of burning.

ATTENTION

and service life of the boiler. The warranty is not valid if the boiler is not sufficiently

cleaned and damaged.

The frequency of cleaning the particular boiler parts is given in the table below:

Cleaning*

Ash removing 1× Space around the ash tray 1× Space under the exchanger 1× Lever of turbulators 5 – 6× Flap 1× Space of the fan 1× Radial impeller of the fan 1×

* The minimum recommended intervals of cleaning. They can be shorter, according to the intensity of operation.

Regular and proper cleaning is important to ensure the permanent output

Weekly Annually

Maintenance once a year or in a case of need (by a qualified person)

Start the burn–down by the menu buttons and wait, until the fuel in the burner burns–out. Turn the burner off by the burner switch and by the main switch, plug out the mains cord of the boiler from the mains socket. Open the door with burner to cca 90°.

1. Put down the burner cover and wipe the photocell by a rag and a soft abrasive agent (tooth paste). Be carefull by the flat cable of display and buttons!

2. Clean the air wings of the fan. The most suitable way is to blow them with compressed air.

3. Screw out the scrape and ignition board.

4. Clean the space behind the ignition board.

5. Scrape ignition board and scraper.

6. Brush the grate utterly and clean the holes in the grate.

7. Mount all the parts back.

8. Clean the container and the pellet feeder from dust and small dirts.

9. Check state of the inlet hose for pellets.

10. Put the pellet feeder into operation by plugging of the feeder´s mains cord into the mains socket (230 V~) to fill it with pellets.

11. Set the amount of pellets to be supplied.

10.2 INSTALLATION AND REPLACEMENT OF THE FIREPROOF PARTS

If you want to make exchange or control of fireproof parts, follow these steps:

1. Start–up the fan

2. Clean the boiler from combustion residues, ash, dust and tars

3. Remove glass sealing cords as shown at the picture

4. Take out the jet

12.1 CHARAKTERISTICS OF TEMPERATURE SENSORS

Characteristics under different temperature sensors are provided below:

1. The boiler temperature sensor readout by PROFI PID controller

2. The flue gas temperature sensor readout by PROFI PID controller

3. The boiler temperature sensor readout by Automatic 8 – 30 or 15 – 50 kW burner

According to the resistance of the sensor and temperature can be easily measured by the electrometer if the sensor is defective and has the right characteristics. Unless sensor indicates values significantly different from the above–mentioned characteristics, or if does not show anything at all, is probably damaged. In this case, the sensor needs to be replaced.

ATTENTION: Temperature and flue gas sensors have the same characteristics, but different temperature resistance. Therefore, the boiler sensor and flue gas temperature

sensor never mix with each other!

USER MANUAL

for correct installation, operation and cleaning

W W W . A T T A C K . S K

Important! Read this manual properly before the boiler start-up!

1. INSTALLATION AND CHIMNEY PARAMETERS

By installation of chimney connection to boiler it is necessary to care about correct outlet of flue gas and eventual condensate, not to let it fall back into the boiler. For this purpose you can use the T-piece, see picture below. Exhaust connection comes into the chimney vent. If it is not possible to connect boiler to chimney vent directly, then the adequate extension of exhaust connection has to be as short as possible, and no longer than 1 m, without additional heating surface and it has to go up in direction to the chimney. Exhaust connections must not go through foreign dwelling or utility units. Internal cross-section of the exhaust connection must not taper in direction to the chimney. Try to minimize usage of elbows by installation. Chimney has to be constructed in conformity with the norms STN 73 4201 and STN 73 4210.

Prescribed values of the correct height and cross-section chimney dimensions:

DPX15, DPX25, DPX35, DPX45 20×20 cm min height 7 m

 20 cm min. height 8 m 15×15 cm min height 11 m

 16 cm min height 12 m

2. VERIFICATION OF THE CORRECT CHIMNEY PARAMETERS

Correct boiler function significantly depends on quality chimney with correct parameters. Minimum chimney diameter is 150 mm, however, 200 mm is recommended. Chimney has to be designed or regulated to achieve prescribed draught of 23–30 Pa at nominal boiler flue gas temperature value.

ATTENTION! Chimney which does not fulfil required parameters may cause limited

boiler function (Low flue gas temperature, low output, excessive condensation of tubular exchanger, shorter life-time, even total boiler disfunction)! Guarantee does not relate to the boiler installed with the chimney of incorrect parameters.

3. DEVICES FOR CHIMNEY DRAUGHT MEASURING

It is possible to check correct chimney draught by some types of analysers or by exact differential pressure-gauge. On the picture there is draught reducer too, also useful for correct draught setting.

4. OPERATION PRESSURE IN HYDRAULIC CIRCUIT

Operation pressure must not exceed limit of 2,5 bar.

ATTENTION! Expanse vessel and safety valve must be installed in the system.

5. BOILER PROTECTION AGAINST EXCESSIVE CONDENSATION – ATTACK-OVENTROP

For correct boiler function and its long life-time it is necessary to keep return water temperature always higher than 65 °C. Set boiler thermostat to 80-85 °C, which is ideal boiler operation temperature. Boiler guarantee is valid only in case that the ATTACK-OVENTROP device was installed into the hydraulic system.

ATTENTION! If the ATTACK OVENTROP device is not installed, it may cause shorter

boiler life-time.

6. CORRECT ASHTRAYS POSITION

Ashtray position is important for correct boiler operation. It is not necessary to take out the ashtray while cleaning, but it is important to check its correct position sometimes. Ashtray has to be completely shifted rearwards.

7. FUEL

Use suitable fuel for wood gasifying boiler operation – soft or hard wood logs. Wood moisture has to be in range of 12–20 % (related to time of min. 15 month of free storing at the fresh air). Alternatively it is possible to use wood briquets of cylindrical shape with opening in the middle.

ATTENTION! Wood with moisture exceeding 20 % shortens boiler life-time, causes

lower output, excessive condensation in tubular boiler exchanger, which may require additional out-of-warranty service!

8. AFTERCOOLING CIRCUIT INSTALLATION

Boiler warranty is valid only in case, that functional thermostatic valve, connected to the cold water source, is installed in the boiler aftercooling circuit. If the cold water source depends on electricity (home water plant), whole device can be out of order in case of power failure. In this cases, use water tanks placed higher than boiler, connected to thermostatic valve. Tank volume has to be appropriate to the boiler outuput.

ATTENTION! If there is no aftercooling circuit on the boiler and it comes to boiler

overheating, serious and non-recurring damage or even fire may occure.

9. CORRECT ADJUSTMENT OF AIR INLETS

Correct adjustment of primary and secondary air by STANDARD and PROFI boilers is marked on tin-plate and it is not necessary to manipulate with that. Correct setting of primary air (upper butterfly) is 100 %, secondary air (bottom butterfly) is set to 35 %. This relates to all outputs of DPX boilers (15, 25, 35, 45).

10. ASHTRAY CLEANING

Internal space of ashtray has to be cleaned from accumulated ash at least 1× a day. Cleaning with scoop is very effective and easy. Cleaning can be done very easily and fast also by full boiler operation.

ATTENTION! Hot ash from ashtray can still smoulder, therefore it is not supposed to

be put into trash bin, however into appropriate tin-plate bin, not to cause the fire.

11. HOW TO CLEAN SPACE AROUND THE ASHTRAY

Space around the ashtray has to be cleaned regularly, at least 1× a week. Use suitable tool, fire hook delivered with boiler is ideal for this purpose. It is not necessary to take out the refractory pieces from the boiler´s ashtray.

ATTENTION! Unsufficiently cleaned space around ashtray may cause limited boiler

function.

12. EXCHANGER PIPES CLEANING BY LEVER OF TURBULATORS

It is necessary to move lever of turbulators cleaning regularly, preferably by every boiler loading, at least 3 times a day. It is necessary to move it by full lever uplift, 5–6 times upwards and downwards.

ATTENTION! If it is not moved with the lever regularly, exchanger pipes may clog

and therefore cause turbulators blockage, lower efficiency, decreased output and incorrect boiler function. In this case is boiler warranty not valid. If you cannot move the lever of turbulators, stop the boiler and call specialized service.

13. HOW TO CLEAN SPACE UNDER EXCHANGER

It is necessary to clean space under exchanger pipes in regular intervals. This interval depends on boiler operation time, but it has to be done at least 1× a week. Remove cover of the opening for cleaning carefully, not to damage the sealing. After cleaning of space under exchanger, install the cover – it has to be sufficiently screwed and air-proof.

ATTENTION! Otherwise there may come to insufficient air circulation in the boiler

and thereby to incorrect boiler function (ineffective combustion, decreased output, low flue gas temperature, etc.).

14. POSITION OF LEVER OF TURBULATORS BY CLEANING

To clean space under exchanger of the DPX 15, 25, 35 boilers, it is necessary to lift lever of turbulators fully up, turbulators go into the pipes and thereby there is free space for cleaning. By the DPX 45 boiler it is ideal to lift the lever into middle position.

15. TOOLS FOR CLEANING OF SPACE UNDER EXCHANGER

To clean space under exchanger it is possible to use fire hook delivered with the boiler.

16. CONTROL OF TUBULAR EXCHANGER´S FUNCTIONALITY

Check regularly correct functionality of tubular exchanger – at least 1× a month. Firstly, remove rear upper cover.

17. ACCESS TO TUBULAR EXCHANGER

Release wing matrices.

18. EXCHANGER´S COVER REMOVAL

Check correct functionality fo turbulators, while the boiler is out of order. Remove the cover to get to the tubular exchanger.

ATTENTION! Cover must be sufficiently tighten and air-proof. Otherwise it may

cause incorrect boiler function

19. CONTROL OF CORRECT FUNCTION OF THE HEAT-UP FLAP

For correct function of the heat-up flap it is necessary to check and clean bearing surfaces regularly.

20. TURBULATOR THREADS CLEANING

If the boiler was from any reason operated in incorrect way, it is possible, that the turbulators were clogged and thereby the flue gas transition was decreased. In this case it is necessary to demount turbulators and to clean the space between particular threads, for example by wire brush. Put the turbulators back into the pipes, not to decrease efficiency of the boiler. (This is not related to the 15 DPX model).

21. CLEANING OF THE VENTILATOR´S OPERATION AREA

Operation space of the ventilator´s radial impeller has to be cleaned at least 1× a year. To do so, release matrices of the ventilator´s flange and demount ventilator. Clean the operation area from soot and mud. By demounting, take care to tighten matriaces of the ventilator´s flange sufficiently.

ATTENTION! Demount ventilator, while boiler is out of order. Insufficiently cleaned

ventilator´s operation area may cause its limited function.

22. CLEANING OF RADIAL IMPELLER’S VANES

Vanes of ventilator have to be cleaned from dirt at least 1× a year by suitable tool (wire brush).

ATTENTION! Too dirty vanes of ventilator decrease its efficiency and thereby cause

limited boiler function.
