Nordyne Intertherm 661057 Lp Burner Orifice

Product Description

The NORDYNE INTERTHERM 661057 is a liquid propane burner orifice designed for use in gas-fired heating equipment. The orifice meters the flow of LP gas into the burner assembly, maintaining the correct fuel-to-air mixture for stable combustion. This is a direct OEM replacement component installed by licensed HVAC technicians and gas appliance service professionals during routine maintenance, burner servicing, or fuel-type conversions from natural gas to LP.

This LP burner orifice is suited for residential and light commercial gas heating applications where liquid propane is the fuel source. LP orifices are sized differently than natural gas orifices to account for the higher pressure and energy density of propane, making it critical to install the correct part for the fuel type in use. Refer to the equipment data plate and service manual to confirm the correct orifice size before installation.
