When transitioning field equipment from natural gas to liquid propane, the Heil Quaker ICP 1148121 Conversion Kit provides the necessary OEM components to ensure manifold pressure and flame characteristics meet manufacturer specifications. This NG to LP conversion kit is a critical requirement for International Comfort Products (ICP) units, including brands like Heil, Tempstar, and Arcoaire. As a veteran technician, you know that precise orifice sizing is non-negotiable; this kit includes #55 and #54 burner orifices along with a 0.012 LP pilot orifice to maintain thermal efficiency and prevent carboning. The package also features a gas valve regulator spring and the required 1002202 installation instructions for field calibration. Using genuine ICP replacement parts ensures that the combustion process remains stable under varying inlet pressures. This ICP furnace conversion kit is designed for a seamless fit, reducing labor time during high-altitude or rural propane transitions where reliable heating performance is mandatory. Key Benefits for Technicians OEM Compatibility: Specifically engineered for ICP, Heil, and Tempstar furnaces, ensuring exact fitment without field modifications. Complete Hardware Set: Includes burner orifices, LP regulator spring, and air shutters to address the higher BTU content of propane. Safety Compliance: Provides official conversion labels to document the change in fuel source for future service and inspections. Performance Integrity: Maintains the intended heat exchanger life by preventing over-firing through precise fuel metering. Common Questions Which burner orifices are included in the 1148121 kit? The kit typically contains #55 (.0550) and #54 (.0520) burner orifices, which are standard for most ICP residential furnace conversions to liquid propane. Is a gas valve adjustment necessary after installing this kit? Yes. After installing the LP regulator spring, you must use a manometer to verify that the manifold pressure matches the rating plate's requirements for propane operation. Can I use this for high-altitude installations? While this kit covers the fuel type change, always consult the manufacturer?s high-altitude tables, as further orifice downsizing may be required for elevations above 2,000 feet.
