• Broad Compatibility: Explicitly engineered for both 80% and 90% efficiency Armstrong gas furnaces.
• Combustion Safety: Provides the correct orifice sizes for stable flame patterns and efficient fuel-to-air ratios.
• Equipment Longevity: Helps prevent burnout and mechanical failure caused by incorrect gas manifold pressure.

Common Questions & Technical Concerns:

Is this kit compatible with other furnace brands?
This is a brand-specific Armstrong Air OEM part. While Armstrong parts are often interchangeable with allied brands like Concord or Ducane, you must verify the specific model number in the service manual to ensure the gas valve and burner assembly are compatible.

What is included in the ALPKT516-4 kit?
The kit typically contains the LP gas orifices, a regulator conversion spring for the gas valve, and required labeling for the conversion record to stay compliant with local mechanical codes.

Can I use this for a 95% or 96% AFUE furnace?
This kit is specified for use with 80% to 90% efficiency furnaces. For ultra-high-efficiency condensing units, please verify the specific part number required, as orifice requirements may vary based on burner configuration.
