How do I determine the flow capacity of the 143-16-023-02 orifice
It functions by creating negative pressure within the heat exchanger
though it is vital to verify specific manifold requirements
By replacing the entire gas burner assembly rather than individual components
33 Amp rating with robust insulation to withstand standard operating temperatures in air-over environments
York S1-029-20423-030 Orifice 321702-401 How do I determine theThe York S1 029 20423 030 Natural Gas Burner Orifice is a precision machined OEM York replacement part designed for specific BTU output requirements in commercial and residential furnaces. Featuring a #30 drill size with a 0. 1285 inch diameter, this orifice is critical for maintaining the correct manifold pressure and stoichiometric air fuel ratio. Field technicians should verify this component against the furnace rating plate to ensure proper
