The Wacker Neuson Nozzle Retainer is a genuine OEM component designed for the HDR 155 Direct Fired Radiant Heater and the HDR 45 direct fired radiant heater series. As a factory-sourced replacement, part is manufactured to the same specifications as the original, ensuring a correct, trouble-free installation in your Wacker Neuson radiant heater. Keeping the burner nozzle firmly and correctly seated is critical to consistent ignition and safe heater operation — this retainer is the part that makes that possible. If your current retainer is worn, cracked, or missing, replacing it with the correct OEM part is the straightforward fix.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original material and dimensional specifications, ensuring the retainer seats the burner nozzle with the correct clamping force and alignment every time.
- Direct Drop-In Replacement: — Engineered to install exactly as the original, with no reworking of the nozzle assembly or surrounding burner components required.
- Confirmed Fitment: — Verified for the HDR 155 Direct Fired Radiant Heater and the HDR 45, covering both models in the Wacker Neuson direct fired radiant heater line.
- Consistent Burner Performance: — A correctly retained nozzle maintains proper fuel spray pattern and combustion, supporting stable heat output and efficient fuel use across the heater's operating range.
- Fuel System Safety: — A failed or loose nozzle retainer can allow nozzle misalignment or displacement during operation, disrupting combustion and creating a potential fuel-handling hazard — replacing it promptly restores safe, controlled burner function.
The nozzle retainer secures the burner nozzle in its precise position within the combustion assembly of a direct fired radiant heater. Holding the nozzle at the correct depth and angle is essential for an even, controlled fuel spray pattern that produces reliable ignition and efficient combustion. When the retainer wears, cracks, or loses its holding ability, the nozzle can shift out of alignment, leading to hard starts, uneven or incomplete combustion, elevated fuel consumption, or an unsafe operating condition at the burner head.
