Reznor 98695 Orifice

Ensuring reliable ignition in Reznor propane heating units requires specialized components that meet exact manufacturer tolerances. The Reznor 98695 Pilot LP Orifice (Y90HC-9733) is a critical metering device engineered specifically for liquid propane (LP) gas pilot assemblies. As an OEM replacement part, this orifice provides the precise BTU output and gas-to-air mixture necessary to maintain a stable pilot flame, preventing nuisance lockouts and ensuring optimal burner transition. Its durable construction is designed to withstand the high-heat environment of a combustion chamber, resisting carbon buildup and corrosion that can lead to irregular flow patterns.

This liquid propane pilot orifice is a direct match for the Y90HC-9733 and 9733-410 assemblies, typically found in Model EEDU and HEEDU duct furnaces. For technicians performing routine maintenance or troubleshooting Reznor gas-fired unit heaters, using genuine Reznor HVAC parts ensures the equipment operates according to its original safety certification and efficiency ratings. This part serves as a foundational component in the pilot light assembly, regulating flow with the precision required for consistent sparking and flame sensor recognition.

Key Benefits for Technicians:

• Compatible with Reznor EEDU and HEEDU series duct furnaces for seamless integration.
• Calibrated specifically for liquid propane (LP) gas flow requirements to prevent over-firing.
• High-quality materials resist typical wear and thermal stress in pilot burner applications.
• Essential for LP conversion kits or restoring pilot flame stability in older units.
• Direct OEM replacement (Y90HC-9733) ensures accurate fitment without field modifications.

Common Questions:

Can I use this orifice for natural gas (NG) applications?
No, this orifice is sized specifically for the pressure requirements of liquid propane. Using it with natural gas will result in an improper flame and potential safety hazards.

Which Reznor models is the 98695 compatible with?
It is primarily utilized in Model EEDU and HEEDU duct furnaces that utilize the 9733 or Y90HC pilot assembly.

How do I know if I need to replace my pilot orifice?
Typical indicators include a lifting pilot flame, persistent yellow tipping, or difficulty maintaining a pilot signal to the flame sensor or thermocouple.
