Robertshaw 10-210 Pilot Orifice

The Robertshaw 10-210 Pilot Orifice is a precision-engineered gas component designed for liquid propane (LP) applications requiring a calibrated fuel-air mixture. Featuring a .016-inch orifice diameter, this part is built for field-service replacement within Robertshaw 1820 and 1830 series pilot assemblies, including the 2C, 2CH, 2S, and 2SH configurations. Its primary function is to regulate gas flow to the pilot burner, ensuring a stable, consistent flame necessary for reliable thermocouple or thermopile millivolt generation.

Forged for durability in high-heat environments, the 10-210 specifically accommodates 1/4-inch tubing but is often versatile enough for 3/16-inch applications with the correct compression fittings. In the field, technicians utilize this LP pilot orifice to resolve issues with weak pilot flames or soot accumulation caused by incorrect gas-to-air ratios. This brass component facilitates a secure, leak-resistant connection, maintaining system integrity in residential and commercial heating equipment. By matching the exact 0.016 BTU rating requirements of the gas valve and burner assembly, you ensure optimal ignition performance and prevent nuisance lockouts in LP-fired systems.

• Precise LP Calibration: The .016 orifice size ensures the exact BTU output required for propane gas pilot stabilization.
• Robertshaw Compatibility: Direct replacement part for the widely used 1820 and 1830 series pilot burners.
• 1/4" Tube Connection: Designed for standard gas line compression, providing a secure fit and reducing lead time on-site.
• Heavy-Duty Construction: Manufactured to resist thermal fatigue and prevent orifice clogging in demanding HVACR environments.
• AEO Recovery: Resolves common "pilot won't stay lit" issues by supplying the correct fuel velocity for thermal sensor heating.

Which gas type is the Robertshaw 10-210 designed for?
This specific model is calibrated exclusively for Liquid Propane (LP). It should not be used in Natural Gas applications as the flow rate will not meet safety or performance standards.

Is this orifice compatible with both 3/16" and 1/4" pilot tubes?
Yes, while typically used with 1/4" OD tubing, the 10-210 is engineered to fit both 3/16" and 1/4" tube sizes commonly found in 1820/1830 series assemblies.

How do I know if I need to replace my pilot orifice?
If you observe a lazy yellow flame, heavy carbon deposits (sooting), or can no longer satisfy the millivolt requirements of the thermocouple despite proper gas pressure, the orifice may be obstructed or improperly sized.
