Viessmann 7868926 Rear Refractory for Bxxe 150/199

Product Description

The VIESSMANN 7868926 is a rear refractory component designed for the combustion chamber of Viessmann boiler systems. Refractory components line the interior of the combustion chamber, protecting the surrounding structure from extreme heat generated during the firing cycle and helping maintain combustion efficiency. This part is installed by qualified HVAC or hydronic heating technicians during routine maintenance, refractory replacement, or combustion chamber rebuild procedures. It is a direct OEM-style replacement that restores the thermal barrier properties of the combustion chamber when the original component shows wear, cracking, or deterioration.

This rear refractory is specifically designated for use with Viessmann BxxE 150/199 boiler models. These are condensing or high-efficiency boiler units commonly found in residential and light commercial hydronic heating systems. When the combustion chamber refractory degrades, combustion quality and heat exchanger protection can be compromised, making timely replacement an important part of system upkeep.

Key Features

• OEM Viessmann part designed to fit the combustion chamber of BxxE 150/199 boilers
• Rear refractory position protects the back wall of the combustion chamber from direct flame and radiant heat
• Designed to restore proper combustion chamber geometry and thermal insulation
• Direct replacement for worn, cracked, or deteriorated original refractory

Compatibility

Designed for use with Viessmann BxxE 150/199 boiler models as stated by the manufacturer.

Installation Notes

Installation should be performed by a licensed HVAC or hydronic heating technician familiar with Viessmann boiler service procedures. Shut down the boiler and allow the combustion chamber to cool completely before beginning any refractory work. Follow all applicable local codes and the manufacturer service documentation when removing and seating the new refractory component. Inspect surrounding combustion chamber components for wear before returning the system to service.
