1INTRODUCTION

Dear customer,

thank you for your trust and purchase of our product – the ATTACK COMBI Pellet boiler. We wish it

serves you reliably for a long time. The reliable and correct function of device is related to its opera-

tion and therefore it is necessary to read this user manual. The manual is written with respect to the

correct function of the boiler.

The correct function of the boiler particularly depends on the following:

•choice of the correct boiler output and type

•perfect commissioning

•reasonable operation

•regular professional maintenance

•reliable service

1.1 GENERAL DESCRIPTION

Name: Water heated boiler ATTACK DPX 25, 30, 35, 40, 45, 50 COMBI Pellet

for wood and wood pellets

Type: ATTACK DPX 25, 30, 35, 40, 45, 50 COMBI Pellet

Max. operating pressure: 250 kPa

El. power supply: 230 V/50 Hz/10 A

El. input: 38 – 78 W

Fuel: Dry wood with heat value of 15 – 17 MJ/kg, moisture of 12 – 20 %,

diameter of 80 – 150 mm

Wood pellets ∅6 mm, l

max

= 35 mm

Nominal output: 25; 30; 35; 40; 45; 49,9 kW

Combi boiler ATTACK® DPX COMBI Pellet is intended for economical and ecological heating of

family houses, cottages, small plants and similar objects.

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 opera-

tion 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 boil-

er´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 re-

sponsible 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 se-

rious 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, suita-

ble 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 jam-

ming of the logs in the loading chamber.

Heat value of different type of wood:

Units

Wood Kcal/kg

MJ/kg

kWh/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.

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 follow-

ing 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 ad-

ditional 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 re-

duced functionality, boiler damage and void warranty. The use of illegal fuel can cause

wrong and uncontrolled combustion.

2ASSEMBLY 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.

The way of boiler manipulation with welded ears

2.2 GENERAL CONDITIONS FOR INSTALLATION

Only a person with valid authorization for installation and assembly of the heat technology de-

vices can install the boiler. The installation requires an appropriate project that is in line with the

valid prescriptions and this instruction manual. Before installing the boiler must the technician

check, if the data given on the production label are in conformity with the data in the project

and the documentation attached to the boiler. The boiler must be connected in line with the

valid prescriptions, regulations and this instruction manual.

ATTENTION: The producer takes no responsibility for damages caused by wrong

connection or operation!
