The PARTS TO YOUR DOOR 50678 is a natural gas to liquid propane conversion kit designed for Peerless MI-series boilers equipped with spark ignition systems manufactured before September 1, 2012. This kit provides the components needed to convert an MI03 or MI06 boiler from natural gas operation to liquid propane fuel. It is intended for installation by licensed heating technicians and plumbers working on residential or light commercial hydronic heating systems. The conversion restores proper fuel delivery, combustion, and ignition performance after the fuel source change.
This kit applies specifically to Peerless MI03 and MI06 cast iron sectional boilers with spark ignition, built before the September 2012 production cutoff. It is not compatible with intermittent pilot or hot surface ignition variants of the MI series, nor with post-September 2012 production units. Installers should verify the boiler serial number and ignition type before ordering to confirm correct fitment.
Compatible with Peerless MI03 and MI06 boilers with spark ignition, manufactured before September 1, 2012. Not intended for use with other MI-series configurations or production dates outside this range.
This conversion must be performed by a licensed HVAC technician or plumber qualified to work on gas-fired hydronic heating equipment. Shut off the gas supply and allow the boiler to cool completely before beginning any service work. All conversion work should comply with local codes and the applicable requirements of the International Fuel Gas Code. After installation, verify all gas connections for leaks using an approved leak-detection solution before returning the system to operation.
