General information on CAA and smoke control
The Clean Air Act 1993 and Smoke Control Areas
Under the Clean Air Act local authorities may declare the whole or part of the district of the authority to be a smoke
control area. It is an offence to emit smoke from a chimney of a building, from a furnace or from any fixed boiler if
located in a designated smoke control area. It is also an offence to acquire an "unauthorised fuel" for use within a smoke
control area unless it is used in an "exempt" appliance ("exempted" from the controls which generally apply in the smoke
control area).
The Secretary of State for Environment, Food and Rural Affairs has powers under the Act to authorise smokeless fuels or
exempt appliances for use in smoke control areas in England. In Scotland and Wales this power rests with Ministers in
the devolved administrations for those countries. Separate legislation, the Clean Air (Northern Ireland) Order 1981,
applies in Northern Ireland. Therefore it is a requirement that fuels burnt or obtained for use in smoke control areas have
been "authorised" in Regulations and that appliances used to burn solid fuel in those areas (other than "authorised"
fuels) have been exempted by an Order made and signed by the Secretary of State or Minister in the devolved
administrations.
The KP12S, KP22S, KP52S, KP62S , KP82S boilers have been recommended as suitable for use in smoke control areas
when burning wood pellet.
Further information on the requirements of the Clean Air Act can be found here: http://smokecontrol.defra.gov.uk/
Your local authority is responsible for implementing the Clean Air Act 1993 including designation and supervision of
smoke control areas and you can contact them for details of Clean Air Act requirements.

IMPORTANT NOTES
This product may only be put into operation by an installation organization trained by the manufacturer.
This product may only be operated by adult persons, duly acquainted with the way the product is controlled and duly
acquainted also with these Instructions. If you adhere to the below mentioned principles, the product will serve you
reliably to your full satisfaction.
1) It is prohibited to intervene in any way in the structure or electrical installation of products. Having the
equipment been disconnected from the electric network, the power supply cord has to be plugged from the
mains outlet.
2) It is prohibited to use inflammable liquids for ignition.
3) No inflammable materials may be stored on the boiler; neither may they be stored within the distance of 1,500
mm from the boiler (except for operating metal fuel bin).
4) In order to preserve long-term service life of the boiler body, it is not recommended to operate the boiler
frequently under the temperature of 55°C, if the boiler is not protected with a primary circuit. The temperature of
55°C should be considered as the minimum temperature.
5) The check how the boiler is filled with fuel is only visual. Any verification with touch is prohibited as it may result
in injury.
6) Never open door of the boiler if there is an ignition process.
7) The door of the boiler has to be always tightly closed. If you´ll perform any check, open the door carefully to
prevent from getting jeopardized by gathered products of combustion or to prevent any sparks flying out from
the boiler from being the cause of any accident. Open the door slowly in order to get the combustion chamber
aerated towards the chimney. This procedure has to be adhered to when the ash is being removed from the ash
pan's space.
8) If any work which generates inflammable vapours takes place in the boiler room (glueing the floor, etc.), the
boiler has to be out of operation and the fire has to be burnt out in the boiler.
9) Having the heating season been finished, clean the boiler thoroughly as per the chapter Maintenance. Products of
combustion stuck to the walls of the exchanger may act corrosively for the whole period of time when the boiler
will be out of operation. If the burner is not cleaned, this may have effect on faulty combustion. We recommend
hire a specialized company to perform this work.
10) If you work on or near to the mechanically movable parts (fuel feeder, etc.), ensure safe disconnection of the
equipment from electric voltage. There is a risk of injury.
11) You should always operate the boiler only under parameters and in harmony with recommendations given in
these instructions for installation and operation. If the boiler works in the AUTO mode and if there is a failure of
current, the boiler will start operation again with the electric firing programme (if this programme has been
installed) after the delivery of electric current is restored.
12) The manufacturer does not assume any liability for errors and subsequent damage caused by unskilled operation
of the equipment or by infringement of principles given in these instructions for installation and operation or by
infringement of generally binding standards and regulations or by using inadequate fuel.
13) If the boiler is moved or otherwise handled with, safety regulations which apply to handling with heavy loads
have to be adhered to.
14) It is prohibited to place heavy loads on jacketing boiler and to step on it. It is recommended to remove the
protective foil after all the building and installation work has been completely finished.
15) External ashtray has to be firmly connected to a boiler fitting while in the operation. Cover of this ashtray has to
be tightly closed. There could be a dangerous escape of combustion gases into a boiler room.

4.3.8 Burner grate
Picture No. 8 Burner
The burner body –is a hollow weldment made from highly legated material with a bottom transversal fuel inlet. The
fuel is delivered by a built-in F2 feeder driven by an electric motor with a gearbox.
A set of slit and round jets in the burning grill ensures inflow of air in order to facilitate controlled full burning of delivered
fuel during its stay in the burner chamber. The burned out fuel is subsequently pushed over the edge of the chamber into
the ash receiver.
The inner space of the burner body is connected to an air fan , whose revolutions can be regulated within a large range
depending on the required boiler output or the type of fuel being used.
Impulse revolution sensor
The gearboxes of the F1 and F2 feeders are equipped with impulse sensors, which ensure safe operation of the boiler.
Connecting hose to the F1 feeder made of inflammable material connect Feeder F1 and Feeder F2. It is part of the
transfer fuel lines. It must meet strict installation rules:
It cannot have significant folds, which would block smooth fuel movement and must be built with inclination of minimum
50º (in a relation to horizontal plane).
Attachment to both adaptors must be tight.
Cleaning burner provides removal of excessive ash or cinder volume from the burner when burning lower
quality fuel. The drive of the cleaning mechanism works together with ash cleaning.

3.7 CLEANING SYSTEM
The automatic cleaning system of the boiler significantly affects time of service-free operation of the boiler.
3.7.1 Ash removal
Ash removal is a complex set of technical and program means, which ensure ash removal from burner heating chamber
to external ash receiver in a regular intervals. The ash is taken out by a spiral conveyor. It is driven by an electric motor
through a toothed chain transmission.
The ash removal system can be mounted on the left or on the right side. Assembly of the particular version is done in the
manufacturing facility based on an order. A professional service firm can perform a change (left/right) at the boiler
location.
The motor is connected to the control unit.
3.7.2 Heat exchanger cleaning
Heat exchanger cleaning is a complex set of technical and program means, which ensure removal of solid waste from
warm water boiler exchanger pipes in regular intervals. The cleaning is performed by linear movement of turbulators in
the exchanger pipes. It is driven by an electric motor through a lever gearbox.
The heat exchanger cleaning system can be mounted on the left or on the right side. Assembly of the particular version is
done in the manufacturing facility based on an order. A professional service firm can perform a change (left/right) at the
boiler location.
The drive motor is connected with the control unit.

3.7.3 External ash container
The external receiver provides space for long-term ash collection outside the burning chamber. It enables long-term
service-free operation even when using fuel with high ash content. It is attached to the boiler with a detent lever. During
boiler operation the lever must be in the lower position and the connecting piping between the boiler and the ash
receiver must be tight. Also the receiver cover must be tightly closed. Both of these requirements prevent burning fumes
release to the boiler room.
The receiver is removed by moving the detent lever to the upper position and pulling it away from the boiler.
Dispensing of the contents to the waste disposal container is best done by two people because of its weight.
