Heil Quaker ICP 1173857 Conversion Kit

When converting to propane gas, precision and pressure regulation are the non-negotiables for stable combustion. The Heil Quaker ICP 1173857 Conversion Kit is the specified OEM propane conversion solution for ICP equipment, engineered to transition systems from natural gas to liquid propane (LP) while maintaining manifold pressure standards and burner efficiency. This natural to propane gas conversion kit is a critical component for technicians working on residential and light commercial furnaces from brands like Heil, Comfortmaker, Arcoaire, and Tempstar. It includes the necessary silver main burner orifices, pilot orifice, and Honeywell gas valve conversion internal components (compatible with VR8200, VR8205S, and SV9500 series valves) to handle the higher BTU density of propane.

Installation requires removing NOx baffles and resetting the manifold pressure to approximately 10" W.C. Using an OEM ICP 1173857 LP conversion kit ensures that orifice sizes (typically #55) are precisely matched to the manifold, preventing under-firing or hazardous carbon monoxide production. For veteran contractors, this kit provides the HVAC replacement parts needed to ensure local code compliance and reliable ignition in cold-weather LP applications.

• OEM Compatibility: Precision-matched for ICP furnace propane conversion across Heil Quaker legacy series.
• Complete Setup: Includes main burner orifices, pilot orifice, and LP regulator spring for a comprehensive field transition.
• Optimized Performance: Engineered for pure propane gas to prevent carbon buildup and manifold soot.
• Direct Fit: Seamlessly integrates with Honeywell VR8204M and related gas valve architectures without manifold modification.

What is the correct orifice size for the 1173857 kit?
The standard kit typically includes #55 silver orifices designed for propane; always verify against the specific furnace rating plate for high-altitude adjustments.

Does this kit include the gas valve regulator springs?
Yes, correctly converting the manifold pressure requires the included LP-specific regulator spring to replace the factory natural gas spring.

Which HVAC brands is this Heil Quaker kit compatible with?
As an International Comfort Products (ICP) part, it is compatible with Heil, Tempstar, Comfortmaker, KeepRite, and Arcoaire units specifying this part number.
