NBU steel wood-burning fireplace, left/right, 11 kW, Ø 200, lift-up door

The NBU three-sided glazed insert combines unique aesthetics with exceptional performance. Beyond its visual appeal, the unit ensures efficient space heating and environmentally friendly wood combustion. Thanks to the use of modern materials and innovative technical solutions, it boasts a striking appearance and intuitive operation. One of its many advantages is the option to connect an external air intake. Decorative glass adds elegance to the insert. Furthermore, it is equipped with a child lock to prevent unauthorized opening of the door.

SECURITY AT THE HIGHEST LEVEL

The insert guarantees safe use, as it features a parental lock that protects against unauthorized opening of the door.

The front of the insert is equipped with heat-resistant ceramic that can withstand temperatures up to 660°C. The installed glass is certified for quality and safety.

The body and front of the insert are resistant to high temperatures thanks to the use of high-quality steel.

The door frame has a closed profile, making it stable and resistant to high-temperature stress. The door seal is positioned in a specially shaped groove, ensuring a secure fit and preventing it from falling off during use.

The insert's excellent sealing is guaranteed by the robust welds performed in a noble gas shield. The steel components are laser-cut using state-of-the-art equipment and then bent on CNC bending machines.

ECOLOGICAL COMBUSTION

The appliance complies with Ecodesign requirements and the BImSchV 2 standard for maximum CO emissions.

CONVENIENT USE

The insert door operates with a lift-up system: the glass panel lifts up. This system is based on a counterweight: blocks with a steel cable run on guides over up to four (two per side) bearing discs, which distribute the door's weight evenly. They move along sliding guides installed in the door frame, ensuring smooth, quiet, and effortless operation. Thanks to the door's lifting and lowering mechanism, a large amount of wood can be loaded at once. An additional mechanism allows the glass to be opened from both sides for easy cleaning.

Furthermore, the appliance is equipped with a window cleaning system: thanks to the so-called air curtain, the airflow is distributed evenly, sweeping across the glass and minimizing soot buildup. This keeps the glass looking attractive and clean for a long time.

The chimney uses a specially profiled bottom plate from TERMOTEC, which makes the combustion chamber deeper and accommodates more firewood.

Keeping the insert clean is easier thanks to the installed grid and the container where the ash collects.

MAXIMUM ENERGY USE

More efficient combustion and longer temperature retention are achieved thanks to the combustion chamber lining with TERMOTEC, a heat-accumulating material that increases the temperature in the home. Furthermore, its smooth, white surface makes a striking addition to the fireplace.

The combustion of fuel particles is enhanced by a deflector that extends the path of the combustion gases. This process also increases combustion efficiency and ensures better energy utilization, thus minimizing harmful emissions into the atmosphere.

The appliance has a triple ventilation system for the combustion chamber, which makes the combustion of wood in the insert ecological and, above all, economical.

The primary air supply to the fireplace stove is provided from the outside via a 125 mm air inlet connection. This air inlet is located in the floor of the insert. It is regulated by a throttle controlled by a single knob located beneath the door, thus preventing errors due to improper use. The entire mechanism operates very quietly and flawlessly.
