Lennox 74M57 Tune-Up/LP to Natural Kit

The Lennox 74M57 Tune-Up/LP to Natural Kit is a conversion package that is intended for Lennox HVAC systems to enable easy conversion from liquid propane to natural gas. It is designed for use with specific Lennox gas furnaces for efficient home or commercial heating and low fuel consumption. The kit contains all the parts required for the conversion process to be as easy as possible and to minimize the amount of time that the system is out of commission. With the help of the kit, more people can use natural gas and, therefore, achieve better fuel combustion, which results in reduced emissions and increased comfort.
