Carrier crlpelev002a00 High-altitude Gas Conversion Kit

Product Description

The CARRIER crlpelev002a00 is a high-altitude natural gas conversion kit designed for small rooftop HVAC units that leave the factory configured for natural gas operation at elevations up to 2000 feet. When a unit is installed above 2000 feet, combustion air density decreases, which affects fuel-to-air ratios and burner performance. This kit provides the components needed to bring the unit back into proper operating specification for high-altitude conditions. Licensed HVAC technicians perform this conversion as part of the equipment commissioning process at job sites located in elevated regions.

This kit applies to small rooftop units that were factory-shipped for natural gas service. It is intended for installations where the equipment will operate above 2000 feet elevation, where standard sea-level gas valve and orifice settings are no longer appropriate. The conversion is also required when the unit will be transitioned from natural gas to liquid propane operation. It is a field-installed kit suited for light commercial rooftop applications.

Key Features

• Converts factory natural gas configuration for operation above 2000 feet elevation
• Also supports conversion to liquid propane service where required
• Designed specifically for small rooftop unit platforms shipped with standard natural gas setup
• Addresses combustion performance concerns caused by reduced air density at high elevations

Compatibility

Designed for CARRIER small rooftop units factory-equipped for natural gas operation at elevations up to 2000 feet. Consult the unit installation manual to confirm this kit is the correct high-altitude accessory for the specific model being serviced.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with local codes and the equipment manufacturer's installation instructions. Shut off gas supply and disconnect electrical power to the unit before beginning any conversion work. Follow all applicable fuel gas code requirements, including IFGC guidelines, when modifying gas train components. Do not operate the unit after conversion without verifying proper combustion and gas valve settings per the manufacturer's commissioning procedure.
