Honeywell 45900446-050B Venturi Tube Original venturi manifold for premix burners and condensing boilers. Honeywell 45900446-050B (Venturi Manifold) is an original component for gas supply systems with premixing (premix burner systems). In warehouse inventory systems, this device is also known under the part number 534.833.908. Model 45900446-050B is a complete analogue of 45900446-050 (the difference may be only in revision or packaging). Purpose and application The venturi manifold 45900446-050B is a key component of the gas-air mixing system. The venturi tube (or venturi manifold) is responsible for creating the necessary vacuum, which draws gas through the gas valve and mixes it with air in a 1:1 ratio, ensuring stable and efficient combustion even when load is reduced to 20% of maximum. Typical applications: Condensing boilers with Giannoni TRIO and DUO heat exchangers: In particular, TRIO 200 and DUO 100 models. Honeywell VK41.5V / VK81.5V gas regulators: Forms a combined CVI-vf system. Systems with forced draft (DC fan): Smooth power modulation is achieved by changing the fan speed. Combined CVI-vf systems: Used for smooth modulation and ignition of fully premixed devices.
