Nordyne Intertherm 661040 Lp Burner Orifice High Altitude

Product Description

The NORDYNE INTERTHERM 661040 is an LP burner orifice engineered for propane-fueled mobile home gas furnaces operating at elevations between 5000 and 5999 feet. At higher altitudes, air density drops, which requires a precisely sized orifice to maintain proper fuel-air mixture and combustion efficiency. This orifice replaces the standard pre-installed orifice on the AHMG1E-090A model, restoring correct flame characteristics and heat output that would otherwise be compromised by altitude. Licensed HVAC technicians and mobile home heating specialists install this component as part of a high-altitude conversion or service call.

This orifice is intended for LP (propane) furnace applications in mobile and manufactured home installations located at high-altitude sites in the 5000 to 5999 foot elevation range. It is a direct replacement for the factory orifice on the AHMG1E-090A, addressing the combustion tuning requirements specific to that altitude band. Installations at elevations outside this range require a different orifice sized to the appropriate altitude specification.

Key Features

• Sized specifically for LP (propane) combustion at 5000-5999 feet elevation
• Direct replacement for the standard orifice on the AHMG1E-090A mobile home gas furnace
• Restores proper fuel-air mixture and flame characteristics at high-altitude conditions
• Designed for mobile and manufactured home gas furnace applications

Compatibility

Designed as a high-altitude LP burner orifice replacement for the Nordyne AHMG1E-090A mobile home gas furnace. For use at elevations between 5000 and 5999 feet only.

Installation Notes

Installation must be performed by a licensed HVAC technician familiar with gas appliance service and applicable codes including the IFGC. Shut off the gas supply at the service valve and allow the furnace to cool completely before removing the existing orifice. Verify that the replacement orifice matches the correct altitude range and fuel type before installation. Do not interchange LP and natural gas orifices, as incorrect sizing creates a combustion hazard.
