Three-sided glazed NBU insert has unique aesthetic and exceptional functionality. Besides visual effects, the insert guarantees efficient heating and ecological wood combustion. Due to the application of modern materials and innovative technical solutions, it is characterized by outstanding look as well as intuitive operation. One of its many advantages is the possibility of fitting an air inlet outside. The elegance of the insert is provided by decorative glazing of glass type. Moreover, a parental lock protects from uncontrolled door opening.
SAFETY ON THE HIGHEST LEVEL
The insert provides operational safety since it has a parental lock, protecting from uncontrolled door opening.
Front of the insert is equipped with heat-resistant ceramic withstanding temperatures up to 660°C. We offer glass certified with quality and safety.
The body and the front of the insert are resistant to high temperatures through the use of high-quality steel.
The door frame is made of a closed profile, which enables stability and resistance to stresses occurring during working in high temperatures. The door gasket is fitted in a specially profiled slot, enabling its tight holding and preventing it from falling out.
Excellent tightness thanks to the solid welding made in the shielded noble gas. Steel elements are laser cut with the help of modern equipment, and then they are bent on CNC benders.
ECOLOGICAL COMBUSTION
The unit meets the requirements of Ecodesign standards and the restrictions of the BImSchV 2 standard, which determines the maximum CO emission.
COMFORTABLE USE
The door works with the “lift up” system – the glass is raised. The system was made based on counterbalance blocks with the steel tripwire working in guideways on 4 (2 for one side) bearing discs, thanks to which the door weight is distributed evenly. They move along sliding guideways fitted in the frame, which guarantees light, silent, and failure-free work. Loading large amounts of wood by lifting up and pulling down the door at one time is possible. An additional mechanism, enabling double-sided glass opening, helps with its cleaning.
Reduced soot deposition through a clean glass system (air curtain). An air curtain separates the glass from the chamber. Thanks to that, the glass doesn’t become dirty and emit more heat into the room.
A Special profiled bottom plate of TERMOTEC is used in this insert. Thanks to that, the chamber of the fireplace is bigger, and a larger amount of wood can be put inside.
Keeping the insert clean is easier thanks to fitted ash grate and container where ash is accumulated.
MAXIMUM USE OF ENERGY
More efficient combustion and longer temperature maintenance by lining the combustion chamber with ceramic material TERMOTEC, accumulating heat, and raising the temperature in the furnace.
Full combustion on the dust thanks to the deflector, which extends the exhaust path. This process increases the efficiency of burning and guarantees better energy use. It also minimizes the emission of harmful substances into the atmosphere.
The insert has a triple air-supply system of the combustion chamber, thanks to which the wood burning in the insert is ecological and, most importantly - economical.
Primary air is supplied to the insert thanks to the built-in 125 mm external air inlet. The air inlet is located at the bottom of the insert. Insert has a cover plate on the back wall and a hole in its base. Thanks to it, the user can choose how to connect the external air kit. Air adjustment is done with a throttle adjustable by a regulator below the door. This solution prevents improper usage. The whole mechanism works quietly and without fail.
The insert is equipped with a clean glass system; thanks to the so-called curtain, the air stream is distributed evenly, covers the glass, and limits settling soot to the minimum. It allows the glass to remain attractive and clean for a long time.
ECOLOGICAL COMBUSTION
NBU model meets the requirements of the restrictive norm BlmSchV 2, determining maximum CO emission.
MODERN DESIGN
NBU pays attention to modern design and aesthetic finishing. It impresses with a harmonic fire vision, giving the interior a unique style. The warmth radiates not only frontally but also laterally.
The insert has singular decorative glass. Thanks to that, it looks elegant and modern. Such a solution visually enlarges the front of the insert and emphasizes the view of the fire.
The door of the insert has a comfortable handle.
