Heil Quaker ICP 1147442 Orifice

The Heil Quaker ICP 1147442 Orifice is a precision-engineered Natural Gas Burner Orifice designed for consistent thermal output and reliable ignition in residential and light commercial forced-air furnaces. This 10-pack of gas orifices ensures you have the necessary inventory for bulk multi-unit maintenance or complete ICP burner manifold overhauls. Each replacement furnace orifice is machined to strict tolerance levels to prevent erratic flame patterns or inefficient gas-to-air mixtures. As an OEM HVAC replacement part, it facilitates direct compatibility with various Heil, Quaker, International Comfort Products (ICP), and Comfortmaker air handlers. Proper installation of the Heil burner orifice is critical for achieving the specified 1,000 BTU per cubic foot rating typical of natural gas systems. When replacing these components, inspect the burner tubes for slag or debris to ensure the direct replacement orifice provides a clean, laminar flow for optimal combustion performance across the heat exchanger passes.

• OEM Compatibility: Engineered specifically for ICP furnace burner assemblies to ensure exact thread pitch and flow diameter.
• Precision Machining: Minimizes turbulence at the nozzle, promoting a stable flame and reducing carbon monoxide risks.
• Bulk Packaging: The 10-pack natural gas orifice quantity is ideal for service technicians managing high-volume maintenance contracts.
• Corrosion Resistance: High-quality brass construction withstands thermal cycling and prevents oxidation within the burner compartment.

Common Service Questions

Can I use these orifices for a propane conversion?
No, these are specifically sized for the lower pressure and higher flow requirements of natural gas heating systems. Propane requires a smaller aperture due to higher manifold pressure.

Will these fit all Heil Quaker furnace models?
While these are common Heil Quaker replacement parts, always verify your specific model number against the ICP parts list to confirm the correct BTU orifice sizing for your manifold.

What is the benefit of replacing the entire set?
Installing a fresh furnace burner orifice set ensures uniform gas distribution across all burners, preventing "hot spots" and extending the life of the heat exchanger.
