Reznor 94777 Burner Tube

The Reznor 94777 Burner Tube is a high-grade OEM replacement part engineered for industrial and commercial gas-fired unit heaters. Constructed from heavy-duty aluminized steel, this aluminized burner tube is designed to withstand the intense thermal cycling common in Reznor HVAC systems. Its aluminum-silicon alloy coating provides critical corrosion resistance, preventing the premature oxidation and scaling that often lead to burner failure in high-humidity or high-combustion environments.

As a factory-direct component, the 94777 ensures a precise fit within the burner manifold assembly, maintaining the exact orifice alignment required for a stable flame pattern and optimal manifold pressure. This part is a standard replacement for Reznor F25-100 and B-series models, where maintaining combustion efficiency is paramount for operational safety. Technicians should prioritize this genuine Reznor part to ensure the internal heat exchanger surfaces are protected from non-spec flame impingement, maximizing the reliability of the single burner assembly.

Key Benefits

• Aluminized Steel Construction: High-temperature corrosion resistance ensures structural integrity under continuous thermal load.
• OEM Precision: Direct replacement part for Reznor F series and B series units, guaranteeing laboratory-tested safety clearances.
• Optimized Combustion: Engineered to provide a predictable flame pattern for clean combustion and reduced pollutant emissions.
• Industrial Durability: Specifically manufactured to handle the rigorous demands of commercial gas-fired unit heaters.

Common Questions

What models are compatible with the Reznor 94777?
This aluminized burner tube is a direct fit for Reznor B-series and F-series (specifically F25 through F100) unit heaters. Always verify your specific model and serial number before installation.

Can I use a standard steel tube instead of aluminized?
Using a standard steel tube is not recommended as it lacks the corrosion-resistant properties of the Reznor 94777, leading to rapid degradation and potential safety hazards.

Why is the burner tube material important?
The aluminized coating prevents the metal from flaking and clogging the burner ports, ensuring consistent heat output and preventing inefficient fuel consumption.
