Heil Quaker ICP 1187327 Conversion Kit

The Heil Quaker ICP 1187327 LP Conversion Kit is a critical OEM component designed for high-efficiency field conversions of natural gas furnaces to liquid propane. This comprehensive gas conversion kit is the direct replacement for the legacy 1186184 model and is engineered for use in a wide range of ICP gas valves. It includes a high-precision regulator spring (92-0659), various burner gas orifices (including #55, #56, 1.25mm, and 1.30mm), and spoiler screws for both condensing and non-condensing furnace configurations. By installing this ICP furnace part, technicians ensure the manifold pressure is correctly regulated for propane’s higher energy density, preventing overheating or soot accumulation in the heat exchanger. The kit also provides critical safety components, including a dedicated low pressure switch and labeled wire assemblies, to maintain system reliability and compliance during propane operation.

Key Benefits:

• Universal OEM Compatibility: Direct replacement for 1186184, 1177458, and 1183388, fitting Heil, Tempstar, and Comfortmaker furnaces.
• Complete Installation Package: Includes essential brass fittings, drill bits, and specific orifices for sea-level and high-altitude setups.
• Optimized Combustion: Features the necessary regulator spring to adjust internal gas valve pressure from natural gas to propane 11" WC standards.
• Safety Compliance: Includes a pressure switch and detailed labeling to ensure the converted unit meets professional safety requirements.

Common Questions:

Can I use the original natural gas orifices for propane?
No. Propane requires smaller orifices due to its higher BTU content. Using natural gas orifices with propane will lead to dangerous over-firing and potential heat exchanger failure.

Why does this kit include a low-pressure switch?
The low-pressure switch is a safety requirement for many propane systems to shut down the furnace if the tank pressure drops below a safe threshold, preventing incomplete combustion.

Is this kit compatible with 2-stage gas valves?
This specific kit is typically designed for single-stage 80% and 90%+ AFUE furnaces. Always verify your specific model number against the manufacturer specifications for multi-stage applications.
