Heil Quaker ICP 1147812 Conversion Kit

The Heil Quaker ICP 1147812 LP to Nat Conversion Kit is a critical OEM component designed for field-converting gas-fired heating units from liquid propane to natural gas. This ICP 1147812 conversion kit includes precision-engineered natural gas orifices and gas valve regulator springs required to adjust manifold pressure from the higher WC (Water Column) of propane down to standard natural gas settings, typically 3.5" WC. As a veteran-grade HVAC replacement part, it ensures the burner assembly maintains the correct BTU input and clean combustion profiles after a fuel source change.

When performing the changeover, technicians must swap the existing orifices and recalibrate the gas pressure regulator to prevent over-firing or carbon monoxide production. This Heil Quaker natural gas kit is specific to International Comfort Products models including Heil, Tempstar, and Comfortmaker units. Using this genuine ICP gas conversion part maintains the technical integrity of the heat exchanger and ensures the system operates within manufacturer specifications for safe fuel conversion.

• Ensures accurate gas manifold pressure regulation when switching to natural gas.
• Includes high-tolerance burner orifices calibrated for natural gas density.
• Mandatory for converting ICP furnace systems previously running on propane.
• Maintains proper combustion efficiency and minimizes soot buildup in the heat exchanger.

Does this kit include the regulator spring?
Yes, this LP to Nat conversion kit includes the necessary internal components to adjust the gas valve regulator for natural gas pressure requirements.

How do I confirm if this fits my specific Heil or Tempstar model?
Compatibility is determined by the model and serial number of your furnace. It is designed for specific ICP gas furnaces; always verify the orifice size requirements in the unit’s technical manual before installation.

Can I use this kit for a Nat to LP conversion?
No, this is specifically an LP to Nat gas conversion kit. Converting from natural gas to propane requires a different kit with smaller orifices and higher-tension regulator springs.
