1.GENERAL WARNING BEFORE OPERATING THE UNIT
Please check the conformity of waste gas , water and electric infrastucture of the area to the
necessary technical parameters where the boiler will be installed.
For safe use of electricity , make sure that the grounding of the installation is isolated and
there is no phase.
Your boiler is under guarantee for 2 years against component and production defects as long
as it is used in line with the suggestions in this manual. Our company cannot be held liable
for any misuse of the product.
Please do not use the boiler out of its purpose. The boiler is designed to supply hot water
(maximum 90°C) to your heating system.
Clean air must always be provided in the area where the boiler is installed. Due to reasons of
security, the installation of the boiler to closed areas with human presence is strictly
forbidden.
Please do not operate the boiler without water. Do not feed cold water to hot boiler. If,for any
reason the boiler temprature is over 90°C do not attempt to feed cold water to the boiler until
the boiler temprature drops down to 40°C. The best solution for over heated boiler is to take
out burning coal outside of the boiler
Please do not drain the system water except repairing or during times of frost. Antifreeze
material can be added to sytem water up to 15%
During operation, the temprature difference between return and flow can be maximum 20 °C.
Water with high calcer rate is extremely dangerous for boiler and installation. In this case,
please use water softeners.Product failures as a result of blocked water passes is out of
scope of factory guarantee.
Each year,before start of heating season,the boiler’s chimney connection and internal parts
must be checked and cleansed. This will enable efficient operation of the boiler.
Please do not take hot water out of the boiler for domestic use purposes.

4.1 INSTALLATION AND WATER FLOOD
Please use open expansion tank for MAKTEK Solid Fuel Boilers. Closed expansion tank
systems may trigger steaming of the boiler when there is an electric cut out or when the
pump is not functioning.
Please connect open expansion tanks according to standarts.
No valve or similar materials must be installed on safety return or flow line of the open
expansion tank.
In order to increase safety if the pump does not function,a by pass line must be secured
between inlet and outlet spot of circulation pump as show in installation schema. The valve
on by pass line should be kept closed during normal functioning . ıf there is an electricity cut
and a risk of overheating appears, 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.
As an extra security measure, an infinite power source may be used for electricty cut.
Please mount 3 bar security valve on the boiler for safety against over pressure in open
expansion systems.
We suggest the mounting of the pump on return line in order to protect from over heating
(steam).
All connections and valve positions must be checked after the installation of the boiler is
complete.
Operations like water flooding or evacuation must be done while the boiler is not working
and cold.
Please flood water to the system until water comes out of warning pipe. Please close the
valves when the filling is complete.
Please purge air in the system where necessary. Avoid any installation that might block air in
the system, if any doubt, please use automatic purger.

BOILER INSTALLATION SCHEMA
10

4.2 AIR CONNECTION
The area where the boiler is installed must always be suppplied with fresh air by using a
window or a duct. In order for a boiler to burn safely and efficiently, fresh air is required.
Otherwise once the burning starts, the oxygen level will drop causing the burning to be
inefficient. In turn, this will result in formation of soot in the boiler and chimney and will require
frequent cleaning.
4.3 CHIMNEY
The chimney that will be connected to the boiler must be private. The chimney must be
connected to provide minimum draught. A boiler without chimney connection should not be
operated.
Chimney connection pipe and pipe systematic should be installed and checked by authorized
people only. May we remind you that the biggest factor in boiler efficiency is chimney design
and draught.
Proper chimney connection pipe should not smaller than the boilers chimney diameter, vertical
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.
We suggest not to use enamel stove pipes as it creates tar in chimney connection pipe or
chimney system.
In case of an elbow use in chimney connection, the elbows must be round with a wide angle.
Quantity of an angle must be minimum 2 pieces.
Chimney connection must be installed to allow demounting from the boiler and avoid gas
leaking.
Chimney connection pipe must not be extended to the outside and must be connected to a
pipe.
The contact of chimney connection pipe with flammable material must be avoided.
Chimney connection pipe must not be pushed inside the chimney.
The direction of the pipe should not be changed, should there is a need ,it must be
positioned by 60 degrees.
The chimney must be leak proof and air transperancy from inside and outside must be
avoided.
No other boiler or device must be connected to same chimney. This would decrease chimney
draught and decrease boiler efficiency.
Parallel chimneys should have no inter connection.
11

There should be no sectional narrow down in any place of the chimney.
Main walls of the building should never be used as chimney wall element. The chimney must be
inside the building, if the chimney must pass from outside, the isolation must be done properly.
The chimney must be frequently cleaned in order to avoid tar and soot and clogs.
Please avoid foreign objects, cement or surface flow inside the chimney, as these will increase
the risk of narrow chimney section and will result in decrease on chimney draught.

ATTENTION !!! Fuel loading and feeding values are in Table 1. Loading and feeding settings
belongs to the fuel only which one used in. It is necessary to do new settings when the fuel type
is changed
SAFETY TERMOSTAT Safety termostat is placed behind the control panel and steps in
breakdown of boiler water setting termostat and prevents the increase of boiler water
temperature. Ensures secondary safety and protects the boiler. Recommended to be set at
80 °C.
IMPORTANT!!!
When any adjustment is not being made on digital display, it shows the boiler water temperature
at that time.
7. FIRST OPERATION AND USE
7.1 First Burning
In first burning, system water must be full and system air must be vented.
Fuel loading must be done over the grate. Grate prevents entrance of foreign materials, big
sized coal pieces inside the bunker and prevents damage to the reducer and loading spiral.
Also passes the proper size of coal which will burn easily and efficiently into the bunker.
Small wood pieces must be ignited with gas and paper for burning the fuel in boiler. Then boiler
gates must be closed and fan must be runned in low speed till full ignition of coal. If fan blows
too much air, slagging of the fuel occurs because of the cooling affect of the combustion
chamber.
Make the fuel feeding and waiting settings according to boiler and fuel type from the
Table 1:
When the ignition is complete, make the reductor button on and make the boiler run with
settings you desire.
Increase the fan speed after ignition and provide the fuel efficiently.
It would be good to set the boiler water temperature at a high degree (70°C) from control panel.
Afterwards this temperature can be set to desired degree.

7.2 WARNINGS FOR USE
Circulation pump will start running when the burning continues and boiler water
temperature comes to 35°C. This prevents extra electric consumption and heats boiler
immediately so prevents damages from sweat of steam. Prevents sending water, which
wasn't heated completely, to the raditaor.
Boiler water temperature decreases when the fuel is finished and when it is 30°C,
circulation pump stops running. When the boiler water temperature decreases to 25°C all
functions stops.
Fan automatically stops running when the boiler water temperature comes to set termostat
degree. Fan starts running when the boiler water decreases 5°C below set degree.
Running and stopping of circulation pump and fan can be followed by blinking leds on
digital display on control panel.
Circulation pump will run automatically 3 seconds in every 24 hours as long as boiler
unpluged. This prevents the failues on pump that can be occurred from long time unuse.
CAUTION!!! If the electricity power goes off, the circulation pump will stop working so the
high heat trapped in the boiler and it will increase the boiler water to the boiling point. In this
case you should do as following;
1. Close the air inlet of the fan completely.
2. DO NOT open the lids of the boiler.
3. If there are by-pass valves installed on the system, open them.
4. When the power comes back, return to your previous adjustments. Follow the steps to
start combustion to start burning in the boiler.

8. CLEANING AND MAINTAINENCE
Following instructions should be followed in order to keep boiler working safe and efficient for
long time.
Quality of the fuel used, would effect the boiler cleaning time, consumption amount of fuel
and efficiency of boiler.
Nut coal is burned in boiler. Do not burn Dust and coke coal. Ash drawers should be cleaned
up every day.
High quality, with high calorie and dry coal should be used in order to get high efficiency.
Smoke pipes inner surface should be cleaned up with a brush and turbulators shoud be
cleaned up with a fabric in every 15 days. Air inflow in burning pot air holes, should be
checked.
Holes which don't have air flow should be opened. Air holes should be cleaned up by running
fan free.
Electricity connection shoul be cut off before the maintainance.
Electricity, chimney, installation connections should be done before winter time.
9. OFFERS FOR ECONOMIC USE
