The Wacker Neuson Burner Nozzle, 3.75gph, 60° is a genuine OEM component designed for the HI750, HI900, and HI1000 series indirect fired air heaters. As a direct source part, meets the original engineering specifications for spray rate and cone angle — two factors that directly determine combustion quality and heat output in these machines. Compatible across a wide range of configurations including diesel, dual-fuel (DGM), surge brake, and electric brake variants, this nozzle covers a broad spread of the indirect heater lineup. Sourcing the correct OEM nozzle ensures the burner fires cleanly and consistently, keeping your heater running at rated capacity.
Key Features
- Calibrated Flow and Spray Angle — Factory-rated at 3.75gph with a 60° cone angle, matching the original combustion chamber design for clean, efficient ignition.
- Genuine OEM Part — Sourced directly from Wacker Neuson, this nozzle is built to the same tolerances as the unit it replaces, with no guesswork on fitment or spray characteristics.
- Broad Indirect Heater Compatibility — Fits HI750, HI900, and HI1000 series heaters across diesel, DGM, surge brake, and electric brake configurations.
- Consistent Combustion Performance — A correctly functioning burner nozzle atomizes fuel evenly, enabling the burner to reach operating temperature quickly and sustain steady heat output in cold-weather applications.
- Fuel System Safety — An incorrectly sized or worn nozzle can cause incomplete combustion, fuel weeping, or ignition failure. Using the OEM-specified 5200018218 ensures the burner operates within its designed safe parameters.
The burner nozzle is responsible for atomizing fuel into a fine, evenly distributed mist before it enters the combustion chamber. The spray rate (gallons per hour) and cone angle are precisely engineered to match the airflow and ignition characteristics of the burner assembly — change either variable and combustion efficiency drops, often leading to sooting, hard starts, or uneven heat output. When a nozzle wears or becomes clogged, the heater may fail to ignite, run erratically, or produce excessive smoke, signaling that replacement is needed to restore proper operation.
