This sign indicates the situations that may cause harm to the
environment, property and animals if the warnings are not
followed.
Protect the power cable from damages and contact with liquids.
The risk of electric shock occurs as a result of contact with
damaged cables.
Cables in contact with liquid may cause electric shock and fire.
Make sure that there is proper grounding in the installation
where the energy connection is made. Use proper cross-section
cables for all electrical connections.
Risk of electric shock where grounding is insufficient. Risk of
fire occurs due to overheating of low-section cables.
Never open the cover while the boiler is operating.Danger
of personal injury as result of the flame coming out of the
combustion chamber.
Do not remove the outer cover sheets of the boiler, do not
open the protective covers. Risk of burning as a result of
contact to hot surfaces and risk of electric shock resulting
from contact with electrical components.
Do not disconnect the boiler from the place where it was
mounted, do not interrupt its connections. During the
disconnecting process, there is a risk of electric shock
resulting from contact with electrical components and water
flood risk resulting from disconnection of water installation.
For safety it is strictly forbidden to install the boiler in
enclosed spaces inhabited with people.The area where the
boiler is installed should be well ventilated and must have
constant fresh air intake.
Do not perform any cleaning or maintenance without
turning the unit off and disconnecting the power supply.
Risk of electric shock as a result of contact with electrical
components.

1.1 GENERAL PRECAUTIONS BEFORE
USING
• Check whether the mounting area complies with the technical
requirements for waste gas installation, water installation and electrical
installation.
• For safety and safe use of electrical installation, make sure that the
isolated grounding is properly done and that the ground line is not phase-
misplaced.
• Your pellet boiler is guaranteed for 2 (two) years against material and
manufacturing defects, provided that the warnings and standarts stated in
the operating instructions are followed. The manufacturer is not
responsible for any faults or damages of the product results from
unintentional, incorrect or unintended use that are against to instructions.
• Do not misuse the boilers. Our boilers are manufactured to provide hot
water (max. 90 degrees) to the heating system. Water should never be
taken from the boiler for domestic use.
• Permanent fresh air should be supplied to the area where the device is
installed. For safety, it is strictly forbidden to install boilers in enclosed
spaces where people live.
• Do not operate boilers without water. Never supply cold water to a hot
boiler. If the boiler temperature has risen above 90 degrees , do not feed
cold water or increase the water level to cool down the boiler until the
boiler temperature decreases below 40 degrees. The best intervention to
an overheated boiler is to throw the burning fuel out of the boiler.
• Water at the installation should not be discharged except for repairing or
frostbite . Antifreeze can be added to the installation water at a rate of
15% against frost hazard.
• When the boiler is running, the difference between the flow and return
water should be at most 20 degrees.
• Water that has high amount of lime are extremely inconvenient for
boilers and installations. In such cases it is necessary to use softening
devices. Defects that may occur as a result of water leaks or blockages due
to lime in the boiler are not covered by the warranty. Every year before the
heating season, the boiler body, chimney connection pipes and chimney
must be controlled and cleaned. In this way, the system can be operated
more efficiently.

4.BOILER MOUNTING
• Boiler should be mounted in balance and mounted on a 10cm higher
platform at the boiler room.
• Boiler should be connected to a well draught chimney and minimum
number of elbows should be used between chimney and boiler.
• The boiler must be located at a place where it can get enough air for efficient
combustion. MAKTEK MKP series boilers are produced with closed expansion
tank and 3 bar safety valve on the device. It is recommended that an additional
safety valve should be installed on device to meet the expansions in the
installation
• Pipes must be cleaned before the initial operation of the boiler.The best
way is to flood water from one side of the pipes and drain it from the other
side.
• The circulation pump should be mounted on the return pipe of the boiler water.
• During mounting, there should be adequate space left for service
intervention, device control and fuel loading
• Valve connection should be made on the boiler water return lines.
• The chimney connections must be leakproof. The chimney connection pipes
of the device must be used at the same diameter without any section narrowing
from the device outlet to the chimney hole.
• Grounding connections of the device should be done, electrical connection
of the circulation pump must be done correctly. Only authorized service
must be called at all electrical faults.

4.1$INSTALLATION$AND$WATER$FLOOD
l A by-pass line should be arranged between the inlet and outlet points of the
circulation pump, as shown in the installation diagram. This is to increase the safety in
the event of a power failure or other case that can cause non functioning of the
circulation pump.The valve on by-pass line should be kept closed during normal
functioning. If there is an electricity cut and a risk of overheating occurs, the valve must
be open and the evacuation of hot water must be provided by natural circulation. The
diameter of the pipe to be used at by pass line should be the same diameter size with the
pipe used in installation at minimum.
l An uninterruptible power supply may be used for electricity cut as an extra security
measure.
l Mount 3 bar security valve on the boiler for safety against over pressure in open
expansion systems.
l It is recommended to mount circulation pump on return line for protecting
it from overheating (stream).
l All connections and valve positions must be checked after the installation of the boiler
is complete.
l Operations like water filling or draining must be done while the boiler is cold and not
working.
l Flood water from filling valve to the system until water comes out of warning pipe.
Close the filling draining valves when the filling is complete.
l Purge the air from the system where necessary. Avoid any installation that might
block air in the system, if any doubt, please use automatic purger.

4.3 VENTILATION
The area where the boiler is installed must always be suppplied with fresh air by
opening a window or a duct. Fresh air is required in order to burn the fuel safely
and efficiently. Otherwise once the burning starts, the oxygen level will drop and
the burning will detoriate. Detoriation of burning will cause decreasing burning
efficiency and filling chimney with soot and will require frequent cleaning.
4.4 CHIMNEY
l The chimney that will be connected to the boiler must be independent. The chimney
must be connected to provide a minimum draught. A boiler without chimney connection
should not be operated.
l Chimney connection pipe and pipe systematic should be installed and checked by
authorized people only. We remind you that the biggest factor in boiler efficiency is
chimney design and draught.
l Proper chimney connection pipe should not be smaller than the boiler's chimney
diameter, horizontal length must not be shorter than 60 cm and longer than 2 meters and
pipe must be connected to the chimney with minimum 10 degree of angle.
l We suggest not to use enamel stove pipes as they cause tars in chimney connection pipe
or chimney system.
l In case of an elbow use in chimney connection, the elbows must have round and wide
angle. Quantity of an elbow must be maximum 2 pieces.
l Chimney connection must be installed to allow demounting from the boiler and avoid
gas leaking.
l Chimney connection pipe must not be extended to the outside and must be connected
to a chimney.
l Chimney connection pipe's contact with flammable material must be avoided.
l Chimney connection pipe shouldn't be pushed inside the chimney.
The direction of the chimney should not be changed. If there is a need to change
directions,it must be positioned horizontally by 60 degrees.
l The chimney must be leak proof and air transperancy from inside and outside must be
avoided.
Do not connect more than one boiler and another device to same chimney. This
would decrease chimney draught and boiler efficiency. There should be no contact
between the chimneys that are placed side by side.
l There should be no sectional narrowing in any part of the chimney.

13
l Main walls of the building should never be used as chimney wall element. Chimney
must be inside the building unless otherwise necessary. If the chimney must pass
from outside, the isolation must be done properly.
l The chimney must be frequently cleaned in order to avoid tar ,soot and clogs that would
prevent chimney draught.
l There shouldn't be foreign objects, cement or surface fragments inside the chimney, as
these would cause narrowing in sections of chimney and result in decrease on
chimney draught.

$$$$$$$$$$$$$ 7.STARTING UP AND USING
Boiler start up must only be done by MAKTEK AUTHORIZED SERVICE.
7.1 INITIAL OPERATION
At first start-up, the system water must be completely filled and air must be
purged from system. The system water pressure should be 1.5 bar on the
manometer at the front panel.
Pellet should be filled in the fuel tank up to 15 cm level to top cover. The first
fuel filling (preloading) to the combustion chamber should only be carried out
by Maktek Authorized Services. This process is only done once before the first
start. Since the fuel level in the fuel tank is controlled by the electronic
sensor, this operation is unnecessary when the fuel is exhausted and while
the boiler is being used
To activate the boiler press and hold the on-off button on the control panel
until the LCD screen opens. The fuel loading and burning process will be
done automatically.During the ignition, the temperature and auto setting
indications will flash interchangeably on the LCD screen.
When the combustion occurs, the burning symbol appears on the screen
and the boiler continues to run automatically at the factory settings.
Factory settings are recommended as user settings and are given in the
table below. The automatic operating parameters can be changed by the
user by taking into account the isolation condition of the building or the
type of pellet used.
The desired boiler water temperature is set by the user with the
temperature setting button hence the automatic operation of the
boiler is provided.
If optional room thermostat connection is available, the user can control the
boiler by adjusting the desired room temperature via the room thermostat.
When the boiler water temperature (room temperature when room
thermostat is used) reaches the level that the user has set, the boiler stops
burning and is put on hold. When the set temperature drops below 3 ° C
from the set temperature, the boiler automatically provides burning and
operates at user settings.

7.2 WARNINGS ABOUT PELLET
Pellets in suitable standarts like 6-8 mm in diameter, 6-30 mm in length, made of
wood with shells peeled, moisture content 10% -15%, minimum 3500-4000 kcal
heat value, no chemicals and additives added should be used in the boiler.Our
company is not responsible for any faults and inefficient operation in case of
using improper pellets as fuel.It is important to make sure that there are no
foreign substances in the pellet.Damage caused by foreign material coming out of
the pellet is not covered by the warranty.
Pellets made of chipboard and MDF powder should never be used in the boiler.
7.3 USING PRECAUTIONS
When the boiler water temperature reaches 30 ° C in burning, the circulation pump is
activated. This prevents both unnecessary electricity consumption and prevents the boiler
from the water vapor damage caused from heating up quickly to sweat. At the same
time, it prevents the circulation of unheated water to the radiators.
The boiler water temperature continuously decreases when the fuel is
exhausted and the circulation pump is deactivated when it reaches 30 °
C. When the boiler water temperature drops down to 25 ° C, all
functions stop.
The fan is automatically switched off when the boiler water temperature
reaches at the set thermostat limit. The fan starts to work again when the
boiler water temperature falls below 5 ° C from the set temperature.
You can control activation and deactivation of the circulation pump, fan and
reductor from symbols on LCD sceen in control panel.
As long as the boiler is not unplugged, the circulation pump will
automatically switch on for 3 seconds in every 25 hours. This prevents faults
that may occur in the pump in case of not using for a long period of time.
ATTENTION!!! In case of power cut, the boiler water may
increase to extreme boiling temperature because it is difficult to control
the high heat in the bunker due to circulation pump stop. For this
reason, please follow the below procedure during a power cut:
