York S1-063-90038-029 Plate

Maintaining proper combustion efficiency in York furnaces hinges on the precision of your venting components. The York S1-063-90038-029 Ventor Plate is an OEM furnace replacement part engineered specifically for high-efficiency heating systems. Featuring a factory-calibrated 1.719-inch orifice, this plate regulates the static pressure and exhaust flow necessary for reliable inducer motor operation and optimal fuel-to-air ratios. Using a genuine S1-063-90038-029 orifice plate ensures that your draft inducer assembly maintains the correct manifold pressure, preventing common issues like pressure switch trips or incomplete combustion. Built from high-grade, corrosion-resistant materials, this York ventor plate 1.719 is designed to withstand the acidic condensate and high temperatures found in the flue transition area. For contractors performing HVAC furnace maintenance, installing this direct-fit 1.719 orifice ventor plate eliminates the guesswork of aftermarket modifications, ensuring the system operates according to original factory specifications and maximizing the service life of the inducer blower.

• Precision Airflow Regulation: The 1.719 orifice size is critical for establishing the correct draft and venting pressure within the heat exchanger.
• OEM Compatibility: As an authentic York HVAC part, it ensures a seamless fit with existing inducer motor assemblies without requiring field drilling.
• System Reliability: Helps prevent nuisance pressure switch lockout errors by maintaining consistent flue gas velocity.
• Professional Grade Durability: Constructed to resist the harsh chemical environment of combustion byproducts.

What happens if I use the wrong orifice size on a York ventor plate?
Using an incorrect orifice size can lead to improper combustion or frequent pressure switch failures. Too large an orifice may reduce static pressure below the switch trip point, while too small an orifice can restrict exhaust and cause overheating.

Is the S1-063-90038-029 compatible with all York furnaces?
No, ventor plates are model-specific. This plate is calibrated with a 1.719-inch opening for specific high-efficiency furnace tonnages. Always verify your model and serial number against the York parts list before installation.

Can this plate be cleaned if it is covered in soot?
While surface debris can be removed, significant corrosion or pitting on the plate can alter the orifice diameter. If the integrity of the 1.719 opening is compromised, replacement is necessary to ensure safety and performance.
