Reznor 9783 Lighter Tube

The Reznor 9783 Lighter Tube is a vital OEM replacement part engineered specifically for gas-fired unit heaters, including the Reznor X, RX, and RPV-200-225 series. This carryover lighter tube ensures consistent burner ignition across the assembly, maintaining the safe and efficient heat exchanger operation necessary for commercial and industrial environments. Constructed from high-grade, heat-resistant metal, the 9783 is designed to withstand the rigorous thermal cycling of natural gas and propane gas heating cycles without warping or premature failure. For contractors handling service calls on older units manufactured prior to 11/86, this lighter tube assembly is often the key to resolving delayed ignition or carryover timing issues. It features precision-drilled pin holes for optimized gas flow and integrates seamlessly with existing manifold screws and drip shields. Utilizing genuine Reznor heater parts like the 9783 maintains the CSA certification equipment standards and prevents the combustion instabilities often associated with generic alternatives.

• Precise Compatibility: Fits Reznor Model Series X, RX, and RPV (sizes 200-225) to ensure exact mechanical alignment.
• Durable Construction: Manufactured with industrial-grade materials to resist oxidation in high-temperature burner rack environments.
• Reliable Ignition: Optimizes flame carryover to prevent gas buildup and ensure smooth startup across all burner tubes.
• Direct OEM Fit: Simplifies field replacement by matching existing manifold and drip shield mounting points.

Common Questions

How do I know if my Reznor heater requires the 9783 lighter tube?
This part is typically required for Reznor unit heaters in the X and RX series, specifically those in the 200,000 to 225,000 BTU range. Always verify your model and serial number on the unit's rating plate to ensure this carryover kit matches your specific burner assembly configuration.

Does this lighter tube work for both natural gas and propane units?
Yes, the 9783 Lighter Tube is engineered to function in both natural gas and LP (propane) systems, provided the correct carryover orifice and gas pressure settings are applied during installation.

What are the signs of a failing lighter tube?
Technicians should look for delayed ignition, localized soot buildup, or visible corrosion on the tube body. If the flame is not carrying over quickly from the pilot to the furthest burner, the tube may be clogged or compromised.
