Nordyne Intertherm 661041 Lp Burner Orifice High Altitude

Product Description

The NORDYNE INTERTHERM 661041 is an LP burner orifice engineered for propane-fired mobile home gas furnaces operating at high altitudes. Burner orifices meter the flow of fuel gas into the burner assembly, and altitude-specific sizing is required because lower atmospheric pressure at elevation affects combustion air density and fuel-to-air ratio. Using the correctly rated orifice at the applicable altitude range keeps combustion efficient and prevents sooting, incomplete combustion, or heat exchanger stress. This orifice is a direct OEM-style replacement part intended for installation by a qualified HVAC or gas appliance technician.

This orifice is designed for use in mobile home LP gas furnaces where altitude correction is required. The input data specifies the following altitude applications: AHMG1E-077A at 2000-2999 ft and AHMG1E-090A at 6000-6999 ft. Installations outside these stated altitude ranges require a different orifice sizing. Verify the furnace model number and installation elevation before ordering to confirm the correct part.

Key Features

• Altitude-specific orifice sizing for accurate fuel metering in low-pressure environments
• Designed for LP (propane) fuel gas — not interchangeable with natural gas orifices
• OEM-style replacement for mobile home gas furnace burner assemblies
• Supports correct combustion air-to-fuel ratio at designated elevation ranges

Compatibility

Compatible with the following model and altitude pairings per manufacturer data: AHMG1E-077A at 2000-2999 ft and AHMG1E-090A at 6000-6999 ft. Confirm the furnace model number and installation elevation before installation.

Installation Notes

Orifice replacement on a gas furnace must be performed by a licensed HVAC technician or qualified gas appliance service professional in accordance with local codes and IFGC requirements. Shut off the gas supply and disconnect electrical power to the furnace before beginning any burner service. Do not reuse a damaged or previously drilled orifice. After installation, verify for gas leaks at all fittings and confirm proper burner flame characteristics before returning the unit to service.
