Armstrong Furnace R28947A006 Pilot Orifice

The Armstrong Furnace R28947A006 is a precision-engineered LP Pilot Orifice designed specifically for Liquid Propane conversions and maintenance in compatible Armstrong and AirEase heating units. Featuring a .010 orifice diameter, this component ensures the exact fuel-to-air ratio required for stable pilot flame ignition and consistent thermocouple or thermopile millivolt production. In the field, using the correct Lennox International replacement parts is critical for avoiding delayed ignition and ensuring the burner assembly operates within designed pressure parameters. This furnace pilot burner orifice is machined to tight tolerances to prevent clogging and carbon buildup, maintaining the integrity of the HVAC pilot assembly. For service technicians, this OEM part provides a direct fit, eliminating the need for field modifications and ensuring that the manifold pressure remains consistent with the manufacturer's venting specifications for LP-fired furnaces.

• Precise .010 Aperture: Calibrated specifically for Liquid Propane (LP) combustion requirements to ensure flame stability.
• OEM Compatibility: Direct replacement for Armstrong R28947-006, ensuring seamless integration with existing pilot burners.
• Durable Construction: High-grade brass machining resists thermal degradation and corrosion within the combustion chamber.
• Optimized Ignition: Facilitates a reliable furnace pilot light for consistent main burner crossover.

What are the symptoms of a clogged pilot orifice?
A restricted or dirty orifice typically results in a weak, yellow flame that fails to sufficiently heat the flame sensor or thermocouple, leading to intermittent furnace cycles or ignition lockout.

Is this orifice compatible with Natural Gas systems?
No, this is a .010 LP Pilot Orifice. Natural gas applications require a larger orifice diameter due to the lower BTU content per cubic foot compared to propane.

Does this include the pilot tubing compression fitting?
This part number refers specifically to the replacement pilot orifice; existing fittings should be inspected for thread integrity during installation.
