The Wacker Neuson XHD Burner C 4.5 Nozzle 45B is a genuine OEM component designed for the HI 770 XHD Indirect Air Heater series, including Arctic Bear XHD and Arctic Bear XHD NS configurations. As a direct Wacker Neuson OEM part, the is manufactured to the exact combustion and nozzle specifications required by the HI770XHD platform — covering both single-duct and dual-duct heater variants. Installing the correct burner assembly ensures the heater fires reliably and delivers consistent, rated heat output across demanding cold-weather jobsite conditions. Confirm your model number before ordering to ensure an accurate match to your specific HI770XHD configuration.
Key Features
- OEM Combustion Accuracy — Manufactured to Wacker Neuson's exact nozzle sizing and spray-pattern specification for the XHD burner, ensuring correct fuel atomization and ignition performance.
- Direct Drop-In Replacement — Engineered to mount directly into the HI770XHD burner chamber using the original hardware and connections — no reworking of the combustion head required.
- Broad HI770XHD Fitment — Compatible across multiple HI 770 XHD Indirect Air Heater builds, including Arctic Bear XHD, Arctic Bear XHD NS, and Extra Heavy Duty Air Heater variants.
- Consistent Heat Output — A properly functioning burner maintains the rated BTU delivery of the heater; a worn or mis-sized nozzle causes incomplete combustion, sooting, and loss of heat capacity.
- Fuel System Safety — Diesel indirect heater burners operate under pressure with ignition cycling; using the correct OEM-spec nozzle and burner assembly is critical to safe, stable combustion and avoiding fuel leak risk.
The burner assembly is the core combustion component of a diesel indirect air heater. It atomizes diesel fuel through a precisely sized nozzle, mixes it with combustion air, and ignites the mixture to generate heat that is then transferred to the outgoing airstream — all without introducing exhaust gases into the heated space. The 4.5 nozzle sizing on this XHD assembly is calibrated to the fuel flow rate and air volume of the HI770XHD platform; using an incorrectly sized nozzle results in poor combustion efficiency, excessive soot buildup, nuisance shutdowns, or insufficient heat output. When the burner degrades or the nozzle wears, the heater loses its ability to reach and hold target temperatures, making timely replacement essential for continuous cold-weather operations.
