Heil Quaker ICP 1162538 Orifices

Upgrade or restore your commercial or residential heating configurations with the Heil Quaker ICP 1162538 Nat Gas Orifices. This professional-grade 10 pack of burner orifices is specifically engineered for high-performance gas regulation in Heil Quaker and International Comfort Products (ICP) equipment. These #42 drill size orifices are precision-machined from high-quality brass to ensure consistent gas velocity and a stable flame pattern, critical for achieving optimal combustion and preventing soot buildup in the heat exchanger.

As a seasoned technician knows, maintaining the correct manifold pressure depends on the precision of these components. The ICP 1162538 is the direct performance replacement for the 1162538-1 and alternate part number 1011351, making it a staple for your service truck when addressing furnace manifold adjustments or burner conversions. These are Natural Gas furnace orifices designed strictly for NG applications; utilizing these for LP without a full conversion kit will lead to hazardous over-firing. Ensure your burner tubes are free of obstructions and that these are seated properly to maintain the intended HVAC gas flow rate and system efficiency.

• Provides precise gas metering for consistent BTU output and stable burner operation.
• Manufactured to OEM specifications for a seamless fit across ICP, Heil, Tempstar, and Comfortmaker furnaces.
• Robust brass construction resists corrosion and thermal stress during extended heating cycles.
• Standard #42 orifice size simplifies field replacements and matches factory sizing charts for Natural Gas.
• The 10-count multipack offers cost-effective stock for high-volume service calls and multi-burner repairs.

Can I use these orifices for a Liquid Propane (LP) conversion?

No. These are #42 orifices specifically sized for Natural Gas. LP requires a much smaller orifice (typically around #54 or #55) to account for the higher energy density and pressure of propane. Using these for LP will cause severe over-firing.

Are these compatible with older 1162538-1 part numbers?

Yes, the 1162538 is the direct manufacturer-recommended replacement for the 1162538-1. They share identical threading and aperture dimensions for full backwards compatibility.

How do I ensure these are not clogged during installation?

Always perform a visual inspection for machining burrs or debris before threading. When cleaning existing orifices, avoid using metal bits or reamers that could enlarge the opening; stick to compressed air or a soft-bristle brush to maintain the integrity of the #42 drill size.
