ÜKY/Duopel Boilers User Manual
INTRODUCTION
Thank you for choosing ÜNMAK ÜKY/DUOPEL series solid fuel boiler. ÜNMAK
ÜKY/DUOPEL series boilers are designed to burn wood pellets with burners and
to burn wood with manually (by hand) feeding on the water grill.
Please read the user manual carefully before installing and operating your
product and keep the user manual for the life of the product. Do not touch or
mix any part of the product other than the places allowed in the user manual.
The installation, maintenance and service of the boiler requires expert technical team.
These operating instructions and regulations should be considered for the installation of the boiler,
the selection of the appropriate location for the installation, the installation of the boiler water
installation and the design of the chimney.
ÜKY / DUOPEL heating boilers only burn pellet fuel in the burner. An aqueous grill is designed in the
middle of the boiler to burn large pieces of solid fuel. Block wood can be easily burned on this grid.
These boilers are used only for heating heating installations, not directly for domestic water heating.
However, it can produce hot tap water with the help of a boiler or heat exchanger. The energy
required for potable water will be taken from the boiler energy.
ÜKY / DUOPEL heating boilers convert the chemical energy of the wood thrown into the pellet or
water grill in the burner into heat energy by combustion and load it on the heating fluid water.
Excessive digits of the burner feed setting by entering more than necessary will cause excessive fuel
to fall into the combustion chamber, and will take longer to burn the fuel.
Combustion circuit, fan, feeding helix and system pump control are carried out by the electronic
control panel supplied with the boiler.
ÜKY / DUOPEL heating boilers can only burn pellet fuels with a burner. Since the powdered fuels will
fly inside the combustion chamber with the system fan, there will be no efficient combustion. Since
powdered fuel will collect more moisture, it will even cause spiral blockage in the feed screw.
Depending on the calorific values of the fuels, the heat passing from the boiler to the water may
exceed the declared values.
Your user manual must be carefully read and kept with the warranty certificate
enclosed, for the lifetime of the boiler.
