MAKTEK Boiler has a high efficiency construction and provides economy by burning fuel fully.
The burner used in MAKTEK Boiler, is a high-quality burner ith superior technology. It provides
high efficiency combustion, hich provides the fuel air mixture at optimum concentration.
GENERAL WARNINGS AND RECOMMENDATIONS
The points to be follo ed by the user during oprating and maintenance are explained in this
manual.
The follo ing suggestions and arnings must be cared in terms of safety and efficiency of the
system.
OINTS TO BE CONSIDER BY USERS
1- Receive your boiler in operative condition together ith your installer system
2- Put your boiler in places here the plumber is suggests.
3- The boiler capacity is in 20.000 Kcal heating po er, and heating more or less is linked to the
amount of radiator to be selected. In this regard, consider the suggestions of your plumber.
4- Prepare the chimney, chimney connection, ater, fuel and electricity connection hen the
central heating system is installed. Take care that the chimney connection is at the shortest
distance.
5- In the summer months hen the boiler is not used, run the boiler at least once a month for 1-2
minutes. This ill remove the chance of the circulation pump becoming trapped in the inter.
A. O ERATION OF THE BOILER
1-Check hydrometer to see if the expansion is filled ith ater. Do this check at any time during
the orking period.
2- Check the fuel tank if it is full ith diesel fuel. Do not use the fuel in the tank until if finishes for
fuel line not to make air.
3- Set your thermostat at the desired temperature (for ex. 50°- 60°-80°)
4- Check that the valve on the fuel line or at the fuel tank outlet if it is open.
5- Run your device by pressing the main control button (on the fron conrol panel )to ON position.

USE OF ROGRAM CLOCK
If the device has a program clock for programming,
a) Set the clock by turning it manually in the direction of the arro on the atch dial.
b) There are small program bars around the dial that correspond to 15 minutes periaods each.
When you ant boiler to run, the boiler ill automatically starts after pulling the bars that are
across the preffered time period.
After adjusting the temperature to the desired temperature, press the main control button to
make the device run.
INSTRUCTIONS FOR USE AND O ERATION OF BOILER WITH HOT WATER
1-In summer use, the boiler must only be operated for hot ater. Selector s itch position
on the electric panel must be placed at mode.
2- MAKTEK Cenrtal Heating Boiler ith Hot Water automatically starts to produce hot ater.
Shortly after the boiler starts running , hot ater is given by opening any hot ater tap.
3- In the summer months, the boiler orks only for hot ater. Thermostat should be set to sho
the boiler thermometer 80°.
MAINTENANCE OF THE DEVICE
The burner in the MAKTEK Central Heating Boiler has a feature that can be easily removed and
installed and the maintenance can be practically done.
1- The burner can be easily removed by loosening the t o imbus scre s on the aluminum flange.
The electrical connection of the burner can be removed by removing the socket on the burner and
removing it from the device.

2- It is enough to remove the burner barrel to reach the part of the burner taht containes the
turbulator, the injector and the electrodes.
3- Dismantling of burner electrodes, injectors and turbulators:
First, the cable headers ith socket are removed from the double electrode.Then the scre
holding the turbulator is loosened and turbulator demounted from its place. The electrode holder
scre is demounted and electrode is removed from its place. The injector can be removed by
means of a key. The replacement of these elements is carried out by reversing the same order.

B. GENERAL USAGE RULES
1- S itch off your device hen you are filling the depot ith diesel and ait for 1 hour ithout
orking.
2- Before restarting the unit, drain the sediment and ater that accumulate on the bottom of the
boiler by opening draining valve.
3- Clean the diesel filters at the outlet of the tank every 30 days. After the filter is cleaned, drain
the air of the circuit.
4- Clean the electrodes and the turbulator of the burner every 6 days ith a dry cloth.
5- Clean it ith a photocell every 60 days.
6- At the beginning of each inter season, clean the soot has accumulated in the boiler.
7- Clean the burner nozzle every 4 months.

2- DATA ABOUT CHIMNEY
Before installing the MAKTEK central heating boiler you need to check hether the boiler is
suitable and sufficient.
a) Chimneys should be made plastered in the sections mentioned in the project of the radiator
installation so as not to receive air from the outside.
b) There should be a fresh air inlet at the ground level and at least 50% of the chimney section in
order to enter the clean air required for combustion in the boiler room. Also, in order to dispose of
the dirty air that can be collected in this area, it is necessary to find open air gap at the ceiling that
ould have the 25% of the cross section of the smoke pipe.
c) A heating system other than its o n heat generator, stove, oven, drying cabinet, ater heater
and other foreign facilities of a can not be connected to the central heating chimney.
d) A leakproof cleaning cap at a suitable size to chimney section must be provided at the lo est
point of the chimneys.
e) Horizontal smoke pipes shall be connected to the chimney ith a slope rising at least 5% and
shall not exceed 1/4 of the height of the chimney height at any time.
f) There must be a hat on the boiler to protect it from rain or sno .
Chimney Section Calculation
F= Free section of chimney cm²
0,03= coefficient
Qk= Boiler Capacity, kcal/h
h= Vertical height of the chimney, m.

Example:
Qk= 20.000 kcal/h (boiler capacity)
h= 15m (chimney vertical height)
F= What should it be?
g) The chimney should be kept a ay from the outer all and generally kept at the mid-point of the
building, ie at the highest part of the roof and at least 80 cm a ay from the roof.
h) The chimney section can be calculated using the formula given belo .
Make the chimney connection in the frame of this information and check the chimney draught.
3- The safety thermostat is set to 90°C. Make sure that the setting is not changed for any reason.
4- If there is no separate place to install the boiler in the apartment, the boiler should be placed in
bathroom, kitchen or balcony. If it is placed in a balcony, it should be kept in a division. The boiler
should never be placed in the bedroom.
5- Check the fuel connection line again to prevent leaks.
6- Your system has close expansion tank. Ensure that the installation is filled ith ater, that the
air collected in the radiators are thro n out, and that the air in the boiler is taken out before
starting to use.
7- Grounded plug is supplied ith the boiler. Ensure that this plug is used ith a grounded socket.
8- Al ays mount the plastic reinforced feet in place hile installing the boiler and adjust the
settings to keep the boiler stable.
9- You must also sign the Warranty Document by submitting the date of delivery and supply the
fuel and make authorized the service to start running of boiler. Deliver it to the user in orking
condition.
