De Dietrich 85565628 nozzle 225B

This is a De Dietrich nozzle, type 225B, listed under catalogue article 336.736.003 and manufacturer codes 85565628 and 336.736.003. It falls under the category of gas nozzles and injectors. In a gas burner, nozzles or injectors meter the gas flow into the combustion head where it mixes with combustion air. The choice of nozzle depends on the burner design, the gas type (natural gas or LPG), and the required flow rate. The orifice size and shape determine the gas velocity and mixing characteristics. When replacing a nozzle, confirm that the thread size, sealing method, and orifice dimensions match the burner specification. Using an incorrect nozzle can affect flame stability, combustion efficiency, and safety. No further details—such as connection size, gas type, or capacity—are provided for this specific article. Use the manufacturer codes to cross‑reference the original burner documentation to verify suitability.
