Armstrong Furnace ALPKT572-3 Conversion Kit

The Armstrong Furnace ALPKT572-3 is a high-precision natural gas to liquid propane conversion kit engineered for specific high-efficiency furnace platforms. This kit enables a seamless transition by adjusting the manifold pressure and orifice sizing to accommodate the higher BTU density of LP gas. Designed for reliability in residential and light commercial forced-air systems, the ALPKT572-3 LP conversion kit ensures proper combustion cycles and minimizes the risk of soot accumulation or flame rollout. Technicians will find this kit essential for Armstrong Air furnace service in rural areas lacking natural gas infrastructure. Each component is manufactured to strict tolerances to maintain the original equipment manufacturer’s performance standards. Proper installation requires a digital manometer to verify manifold pressure adjustments and ensure the gas valve operates within the specified WC range. This OEM furnace part provides a direct fit, reducing labor time during field conversions while ensuring the heat exchanger operates at peak thermal efficiency.

Key Benefits

• Optimized Combustion: Precision-drilled LP gas orifices ensure the correct fuel-to-air ratio for clean burning.
• System Compatibility: Engineered specifically for Armstrong and AirEase gas valves to bypass common field-fitment issues.
• Simplified Field Conversion: Includes all necessary springs and components to modify the regulator settings without replacing the entire valve assembly.
• Enhanced Reliability: Heavy-duty components designed to withstand the corrosive properties of liquid propane impurities.

Common Questions

What is the typical manifold pressure for this LP kit?
Standard installations usually target 10 inches of water column (WC), but technicians must always verify the specific rating on the furnace nameplate after installing the ALPKT572-3.

Is a new gas valve required for this conversion?
No, this kit is designed to modify your existing compatible Honeywell or White-Rodgers gas valve used in Armstrong furnaces from natural gas to propane operation.

Can this kit be used for high-altitude installations?
While this kit covers standard LPG conversion, additional derating may be necessary for installations exceeding 2,000 feet above sea level based on local codes and manufacturer guidelines.
