This kit works great! A replacement for our 22 yo Lennox G51MP Elite Series unit! The adapters worked great. READ the instructions because multiple models use this and each connects the wires a little different.You MAY need to buy the 21D64-2 igniter kit too! This is IMPORTANT. The documentation tells you, but you see the documentation AFTER you receive it.Pay attention to the boards with the * on them on the Amazon description page. That indicates you MUST upgrade the old style igniter.In my case I had the Lennox SureLight 97L4801 version 1 board with a different voltage igniter so had to get the upgrade kit!!!Pay CLOSE attention to the wire on this because the Flame Sense is IGNORED on the new board, but still run to a ground with an adapter pin.
