Hot Water Boiler with Steel Body, Automatic Fuel Feed Operation and Maintenance Manual
INTRODUCTION
We would like to thank you for your choice of ÜNMAK automatic feeding solid
fuel boilers.
Please read the user manual carefully before installing and operating your
product and keep the instruction manual for the duration of use. Do not touch
or mix any part of the product except where permitted in the user manual.
The installation, maintenance and service of the boiler require a specialist
technical team.
These operating instructions and regulations should be considered for the installation of the boiler,
selection of the location for installation, installation of the boiler water installation and the design of
the chimney.
ÜNMAK automatic fuel feed boilers are high-efficiency, steel-fired hot water boilers designed to burn
only solid fuel. 10-18 mm diameter coal (sold in the market under the name of hazelnut coal), and
granule size up to 25x25 mm are suitable for burning coal. These boilers are only used for heating of
the heating system and are not suitable for direct water heating. However, it can produce hot water
with the help of a boiler or heat exchanger. The energy required for domestic water will be taken
from the boiler energy.
ÜNMAK automatic fuel feed boilers are heating boilers convert the chemical energy of the fuel in the
fuel loading tank to the heat energy by burning and load it on the water which is the heating fluid.
Excessive fuel accumulation to the combustion chamber will be kept longer than necessary and the
fuel will take longer to burn.
The combustion circuit, the fan, the supply auger and the system pump control are carried out by the
electronic control board supplied with the boiler.
ÜNMAK automatic-loading boilers can only burn granular fuels up to 25 mm in size. Powdered fuels
will not be an efficient combustion for flying in the combustion chamber with the system fan. Powder
fuel will collect more moisture, even in the spiral will cause helical blockage. Depending on the
calorific values of the fuels, the heat from the boiler to the water may exceed the declared values.
Please read your user manual carefully and it should be kept with the warranty certificate
for the life of the boiler.
