Armstrong Furnace R28947A008 Pilot Orifice

The Armstrong Furnace R28947A008 Pilot Orifice is a precision-engineered component designed specifically for natural gas (NAT) furnace pilot assemblies. Engineered to maintain a consistent pilot flame, this orifice ensures reliable ignition in various Armstrong and Lennox HVAC systems. As a critical replacement part for residential heating units, it provides the exact flow rate required to prevent pilot dropouts and sensor failures. This component is manufactured to meet strict tolerances, reducing the risk of improper fuel-to-air ratios that lead to carbon buildup on the thermocouple or flame sensor. When replacing an obstructed or corroded orifice, the R28947A008 restores the pilot assembly to original equipment manufacturer (OEM) performance standards. Contractors should verify the pilot burner model before installation to ensure a gas-tight fit. Utilizing this gas furnace pilot replacement part ensures system longevity and optimizes the combustion cycle during high-demand heating periods.

• Precise Gas Flow: Optimized for natural gas Armstrong furnace applications to ensure stable ignition.
• Durable Construction: Built to withstand high temperatures within the pilot burner housing without deformation.
• System Compatibility: Direct fit for numerous Armstrong and AirEase pilot assemblies, reducing diagnostic time.
• Improved Reliability: Prevents nuisance service calls related to pilot outages and weak flame signals.

Is this orifice compatible with Propane (LP) systems?
No, this specific part is calibrated for natural gas. Using it with LP will result in improper combustion and potential safety hazards.

How do I identify if the pilot orifice is clogged?
If you observe a small, lifting, or yellow pilot flame, the orifice likely has debris blockage or oxidation requiring replacement.

Does this fit all Armstrong furnaces?
It fits many legacy and modern units, but you should always check your specific furnace parts list or model number for verified compatibility.
