Product Description

The NORDYNE INTERTHERM 661036 is a liquid propane (LP) conversion orifice used in gas-fired heating equipment. Orifices meter the flow of fuel gas into the burner assembly, directly affecting combustion efficiency and heat output. This component is installed when converting a unit from natural gas to LP service or when replacing a worn or damaged orifice. Licensed HVAC technicians and gas appliance service pros handle this type of work as part of fuel conversion or burner service calls.

This LP orifice is suited for residential gas furnaces and heating appliances that use propane as the fuel source. It is installed at the burner manifold, where precise orifice sizing ensures correct gas pressure drop and proper air-fuel mixture for clean combustion. Proper orifice selection is critical any time a unit undergoes a fuel-type conversion or burner overhaul.
