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 KP12, KP22 and KP62 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.

1IMPORTANT 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 a 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 7 - 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 to 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.

Picture No. 6 Terminal with USB
4.2.2.1Description
The HZS 555-S is an intelligent terminal for programming and visualization of automated processes. Process
diagnosis as well as operating and monitoring automated procedures is simplified using this terminal.
A touch screen serves as the input medium for process data and parameters. The output is shown on a 5.7"
SVGA TFT color display.
Cleaning the Touch Screen
CAUTION!
Before cleaning the touch screen, the terminal must first be turned off to avoid unintentionally
triggering functions or commands!
The terminal's touch screen can only be cleaned with a soft, damp cloth. To dampen the cloth, a screen-cleaning
solution such as an antistatic foam, water with detergent or alcohol should be used. First spray the cleaning fluid
on the cloth and not directly on the terminal. The cleaning solution should not be allowed to reach the terminal
electronics, for example, through the ventilation slots.
No erosive cleaning solutions, chemicals, abrasive cleansers or hard objects that can scratch or damage the
touch screen may be used.
If the terminal is soiled with toxic or acidic chemicals, quickly and carefully clean the terminal to prevent
corrosion.

4.3 BURNER HEATING CHAMBER INCL. FEEDER F1 WITH INDEPENDENT
DRIVE
The heating chamber is depicted in picture Nr. 1 and is comprises of these parts:
4.3.1 The burner body
4.3.2 Feeder F2 including the drive
4.3.3 Impulse sensor
4.3.4 Flexible hose
4.3.5 Primary fan
4.3.6 Electric resistence spiral for automatic ignition
4.3.7 Cover of spiral
4.3.8 Burner grate
Picture No. 7 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. (See MENU 11.9 Fans –chapter
9.4.9).
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 an
inclination of minimum 50º (in a relation to horizontal plane).

Cleaning of KP62 burner provides removal of excessive ash or cinder volume from the burner when burning
lower quality fuel. The drive of the cleaning mechanism is works together with ash cleaning.
 Note: Use of alternate fuels requires change of the burner type and also change of boiler program setup.
 Note: The cleaning mechanism burner drive and its installation are depicted in chapter 4.7 –Cleaning system.
CERAMIC PARTS
These parts are an inseparable component of the combustion chamber of the boiler and
they have a major influence on the quality of burning.
