Description
The Resideo 45900446-052/B Venturi is a gas-air mixing component used in premix burners and combustion control assemblies. It operates on the concept where airflow created by a fan generates a pressure differential that draws and mixes gas through a narrowing passage to maintain a controlled fuel-to-air ratio. It is typically installed within gas-fired furnaces, boilers, and premix heating units as part of the modulation and gas valve assembly during system manufacturing or replacement servicing. It helps as a key mixing and regulation element, stabilizing combustion and burner performance in HVAC systems.
