NIBE Rear Wedge Stone For Alpha Keram/UB/Combi
Description
NIBE rear wedge stone is a specially manufactured ceramic component developed for fireplaces and wood-burning boilers in the Alpha series. This refractory stone is placed in the rear part of the combustion chamber and plays a crucial role in directing the flue gases and insulating the combustion chamber. By maintaining the correct geometry and closure in the fireplace, high efficiency, stable operation and cleaner combustion are achieved when burning wood.
Durability and function of the wood-burning boiler
Ceramic components in wood-burning boilers are naturally exposed to extreme temperature differences and continuous wear over time. When a rear wedge brick wears or cracks, air flows can be disrupted, which negatively affects heat transfer and the combustion process. Replacing worn combustion bricks and wedge bricks with new original parts contributes to:
- Maintaining the boiler's intended combustion temperature and clean emissions
- Protecting underlying sheet metal and steel structures from direct heat
- Even air distribution and controlled draft through the ceramic insert
- Long-term reliable operation during cold heating periods
Materials and construction
This wedge brick is cast in robust, heat-resistant refractory material that can withstand direct contact with embers and hot flue gases. The angled shape is precisely adapted to fit tightly against adjacent ceramic parts in the boiler and keep the structure stable without play.
Compatibility and model adaptation
The rear wedge is designed to fit specific variants of NIBE wood and combi boilers:
- NIBE Alpha Combi (model versions: 069012, 089825)
- NIBE Alpha Keram (model version: 089806)
- NIBE Alpha Keram Ub (model version: 089809)
