The Wacker Neuson 5.5 x 60b Hi900 Burner Nozzle is a genuine OEM component designed for HI900D, HI900DGM, HI1000, and HI1000DGM series indirect air heaters. As a direct OEM replacement, part is manufactured to the same specification as the original, ensuring the burner assembly performs exactly as intended. This nozzle is confirmed to fit multiple HI900 and HI1000 configurations, including diesel and DGM variants with both surge brake and electric brake setups. Ordering the correct OEM part by number eliminates guesswork and keeps your heater operating at peak output through demanding cold-weather jobsite conditions.
Key Features
- OEM Spray Geometry: — Manufactured to the exact 5.5 x 60-degree spray angle specification, delivering the correct fuel atomization pattern the Hi900 burner assembly requires for efficient combustion.
- Drop-In Burner Replacement: — Threaded to the original nozzle dimensions, part 5200013958 installs directly into the burner head without rework or adapter fittings.
- Broad HI900 and HI1000 Coverage: — Fits HI900D, HI900DGM, HI1000, and HI1000DGM indirect air heaters across diesel and DGM configurations, including surge brake and electric brake variants.
- Consistent Heat Output: — A worn or clogged nozzle disrupts fuel atomization, causing hard starts, sooty flame, and reduced BTU output; a fresh OEM nozzle restores full rated heating capacity.
- Fuel System Safety: — Correct nozzle sizing is critical in indirect-fired diesel heaters; using a properly rated OEM nozzle helps prevent over-fueling, incomplete combustion, and hazardous flue gas conditions on enclosed worksites.
The burner nozzle in an indirect diesel air heater is responsible for atomizing fuel into a fine, evenly distributed mist before it enters the combustion chamber. The spray angle and flow rate stamped on the nozzle — in this case 5.5 x 60 degrees — are precisely matched to the burner's air volume and combustion chamber geometry, so any deviation affects flame shape, heat transfer efficiency, and emissions. When a nozzle wears, clogs, or is replaced with an incorrectly rated unit, the heater may exhibit hard starting, pulsing flame, carbon buildup on the heat exchanger, or a noticeable drop in output temperature — all signs that the nozzle should be inspected and replaced as part of routine seasonal maintenance.
