York S1-329-20425-001 Carryover Tube

The York S1-329-20425-001 Carryover Tube is a critical OEM replacement part designed for precision gas furnace ignition sequences. Engineered with a dedicated bleed hole, this component ensures reliable burner flame transfer across the manifold, preventing delayed ignition or "hard" starts that can compromise heat exchanger integrity. Its 1/2-inch metal construction is built to withstand the high-thermal environments adjacent to the burner assembly, providing consistent fluid and gas transfer within York, Coleman, and Luxaire heating systems. This furnace carryover tube is essential for maintaining the factory-specified timing of the pilot-to-burner flame carryover, which is vital for system safety and operational efficiency. By eliminating trapped air and stabilizing pressure, this genuine York part maintains the intended combustion performance and prevents nuisance lockouts. For contractors, utilizing Source 1 hvac parts like the S1-32920425001 ensures exact fitment and restores the unit to its original engineering specifications without the risks associated with generic alternatives.

• Precision Flame Stability: The integrated bleed hole architecture ensures consistent gas flow for reliable burner ignition.
• OEM Compatibility: Specifically engineered for York, Coleman, and Luxaire gas furnaces to match factory tolerances.
• Enhanced Safety: Reduces the risk of delayed ignition by ensuring rapid flame propagation across all burner segments.
• High-Temperature Durability: Robust metal construction prevents deformation and maintains flame carryover alignment under extreme heat.

What is the purpose of the bleed hole on the S1-329-20425-001?
The bleed hole allows for the expulsion of trapped air or excess gas pressure, which stabilizes the flame as it travels through the carryover tube, ensuring a smooth transition from the pilot or first burner to the rest of the assembly.

Is this carryover tube compatible with other brands?
Yes, as a Source 1 genuine part, it is the standard replacement for various Johnson Controls brands, including Fraser-Johnston and Guardian, provided the part number matches the service manual.

How do I know if my carryover tube needs replacement?
Technicians should look for signs of heavy oxidation, clogging in the bleed hole, or physical warping, which can cause erratic ignition or "stalling" air bubbles in the combustion cycle.
