Viessmann 7831456 Radial Fan
The Viessmann 7831456 Radial Fan is a high-performance RG148 assembly engineered specifically for Vitodens 200-W WB2B series gas condensing boilers. As a critical component for combustion air supply and flue gas extraction, this fan ensures the necessary static pressure to maintain efficient modulation across the boiler's firing range. Designed for the WB2B-45 and WB2B-60 models, it features a brushless EC motor and a durable die-cast aluminum housing, providing consistent RPM feedback to the boiler control board to prevent F5 fault codes and ensure safe equipment operation.
For professional contractors, the Viessmann 7831456 is a direct-fit solution that includes all necessary radial fan gaskets to maintain a gastight seal at the mixing unit and burner interface. This 120V radial blower is built to ebm-papst engineering standards, capable of high-speed air movement while minimizing vibrational resonance. Using genuine OEM Viessmann boiler parts like this 7831456 fan is essential for maintaining the factory-specified air-to-fuel ratio and preventing premature component failure in high-efficiency hydronic heating systems.
Key Benefits for Technicians:
- Precision Compatibility: Engineered for seamless integration with Vitodens 200-W WB2B 45/60 series boilers.
- Enhanced System Reliability: Restores proper airflow to resolve Viessmann F5 error and combustion lockout issues.
- Integrated Sealing: Shipped with high-temperature fan gaskets for a secure, leak-proof installation.
- High-Efficiency EC Motor: Features an ebm-papst RG148 motor for precise modulation and lower power consumption.
- Industrial-Grade Construction: Built with ball bearings and a die-cast aluminum chassis for sustained operation in demanding thermal environments.
Common Questions:
What boiler models use the Viessmann 7831456 fan?
This radial fan is primarily designed for the Vitodens 200-W WB2B series residential gas condensing boilers, specifically the 45kW and 60kW models (WB2B-45 and WB2B-60).
Does this fan resolve the Viessmann F5 fault code?
The F5 fault often indicates a fan speed issue or a communication failure between the fan and the PCB. Replacing a worn or malfunctioning motor with the 7831456 is the standard professional fix when the fan fails to reach required RPMs.
Are the gaskets included with the 7831456 assembly?
Yes, this Viessmann fan kit arrives with the necessary sealing gaskets to ensure a proper interface with the burner housing and to prevent flue gas leakage during operation.
