Lochinvar & A.O. Smith 100166697 Venter Assembly

The Lochinvar & A.O. Smith 100166697 Venter Assembly is a critical OEM replacement part designed for high-efficiency commercial and residential water heaters and boilers. As a universal venter assembly, this unit directly replaces legacy part numbers including PVT1012, ensuring seamless integration with existing exhaust systems. It features a high-performance draft inducer motor designed to handle the precise venting requirements of forced draft burners. In a typical HVAC combustion cycle, this assembly pulls air and gas through the venturi and forces hot flue gases through the helical heat exchanger before exiting the exhaust connection. This assembly is engineered for durability, operating at a 120V AC nameplate voltage with a balanced blower wheel to maintain consistent RPM and static pressure. For technicians, using this genuine Lochinvar part is essential to maintaining CSA certified safety standards and preventing ignition failure faults often caused by aftermarket blowers with incorrect PWM signal timing or pressure switch calibrations.

• Direct OEM Swap: Engineered as a drop-in replacement for part PVT1012, reducing field modification time for Lochinvar and A.O. Smith units.
• Optimized Combustion: Maintains the specific static pressure required to force flue gases through complex helical heat exchangers.
• Reliable Signal Integration: Fully compatible with Central Control Boards (CCB) using pulse width modulation (PWM) for variable speed control.
• Durable Construction: Features a high-torque motor and robust blower housing to withstand continuous thermal cycling in high-efficiency water heaters.

Is the 100166697 compatible with PVT1012?
Yes, the 100166697 is the official manufacturer-designated universal venter assembly replacement for the PVT1012.

Does this assembly include the necessary gaskets?
While the blower is the primary component, technicians should verify if the blower flange gasket requires separate replacement depending on the specific Lochinvar boiler or water heater model.

How do I troubleshoot a Venter Assembly failure?
Check for 120V at the 3-pin high voltage socket and verify the PWM signal at the 5-pin low voltage socket. If the blower fails to modulate or results in a blocked flue error, the assembly or pressure switch may require replacement.
