Wacker Neuson 5000183977 Standard Elevation Burner Nozzle

The Wacker Neuson is a genuine OEM Standard Elevation Burner Nozzle designed for the HI 400HD D, HI 120, and HI 120HD indirect air heaters. As a direct OEM replacement, this nozzle is produced to the same specifications as the original component — meaning the fit, flow characteristics, and combustion geometry are exactly what these heaters were engineered around. Whether you're servicing a single HI 120 on a small job or keeping an HI 400HD D running through a demanding cold-weather pour, part number gets the burner back to full operation with no guesswork. Source it from an authorized Wacker Neuson parts supplier for full confidence in authenticity.

Key Features

• OEM Fuel Atomization Accuracy — Manufactured to the original spray pattern and orifice geometry, ensuring the burner combusts fuel efficiently at the correct elevation setting.
• Drop-In Burner Replacement — Engineered to seat and seal exactly like the factory nozzle, connecting directly to the existing burner assembly without adaptation.
• Broad Heater Compatibility — Fits the HI 400HD D, HI 120, and HI 120HD indirect air heater models, covering a range of heating capacities in the Wacker Neuson lineup.
• Consistent Heat Output — A correctly functioning burner nozzle maintains steady combustion, which translates to stable outlet air temperature and predictable heating performance on site.
• Fuel System Safety — A worn or degraded nozzle can cause incomplete combustion, fuel misting, or irregular flame patterns; replacing it with genuine OEM part 5000183977 restores safe, controlled burner operation.

The burner nozzle is the point in an indirect air heater where diesel fuel is atomized and introduced into the combustion chamber to be ignited. It controls the spray pattern, droplet size, and fuel flow rate — all of which directly affect how cleanly and completely the fuel burns. When a nozzle wears, becomes clogged, or degrades, combustion becomes uneven or inefficient, leading to hard starts, sooty exhaust, reduced heat output, or in worse cases, unsafe burner behavior. Replacing it promptly with the correct OEM nozzle restores clean ignition and reliable heat delivery.
