Reznor 65978 Burner Rack

The Reznor 65978 Burner Rack is a high-performance OEM replacement part engineered specifically for technical compatibility with Reznor RX-400 series heating units. Fabricated from heavy-duty aluminized steel, this burner assembly rack is designed to withstand the high-temperature environments typical of industrial gas-fired systems while providing superior corrosion resistance compared to standard carbon steel. This rack serves as the structural foundation for the inshot burners, ensuring precise alignment for optimal flame pattern and combustion efficiency. For veteran contractors, the Reznor 65978 is a critical component for restoring the factory-spec performance of unit heaters and duct furnaces. Proper structural integrity of the rack is non-negotiable for maintaining the correct manifold pressure and preventing flame rollout. This industrial heating part is manufactured to strict tolerances to ensure a seamless fit during field replacement, reducing labor hours and ensuring the long-term reliability of the combustion chamber section without the need for field modifications.

• Precise OEM Fit: Drop-in compatibility for Reznor RX-400 units ensures alignment with existing gas manifolds and orifices.
• Enhanced Durability: The aluminized steel construction offers significant resistance to oxidation and thermal scaling.
• Optimized Combustion: Maintains the critical spacing required for inshot burners to deliver a stable, efficient flame.
• Field Reliability: Robust design minimizes the risk of structural warping under constant thermal cycling.

Is the Reznor 65978 compatible with all RX series units?
This specific rack is engineered for the RX-400. Always verify your heater's full model and serial number to ensure exact burner rack compatibility.

Does this burner rack include the burners or orifices?
The 65978 is the structural aluminized steel rack only. Individual Reznor burner components, orifices, and gas valves must be sourced separately if needed for a full rebuild.

What are the signs that a burner rack needs replacement?
Technicians should look for significant scale buildup, structural sagging, or rusted-out mounting points that prevent the burners from seating correctly against the manifold.
