A York S1-02920422056 Pilot Orifice meters fuel flow for stable ignition and controlled burner performance within the heating and cooling system.
The pilot orifice meters gas flow to the pilot assembly so the heating and cooling equipment can maintain proper ignition and stable burner performance. Its precise #56 sizing and 0.0465-inch diameter are essential because even small variations can affect flame characteristics, combustion efficiency and overall HVAC system reliability.
The pilot orifice might be wearing out if the unit shows delayed ignition, an unstable pilot flame or inconsistent heating performance during operation. Physical signs can include clogging, corrosion or visible debris around the opening and environmental signs may include dirt, moisture or fuel contamination that can restrict proper gas flow.
