Flame rectification flame proving system . . .

[Bain]

I saw this sticker on a gas furnace earlier today and had no clue what it meant. I thought it may have something to do with a conversion to propane, but there was a natural-gas meter outside.

Does anyone know what this means? Was the pilot light replaced with an electronic ignition?

They are both safety devices that sense a flame and shut down the gas valve, if the flame is not present.

I'm not sure how it works, but a "radiant flame proving system" was the subject of failures and a recall for at least 1 manufacturer.

A "flame rectification proving system", uses an electrical current to detect the presence of a continuous flame. This was probably a replacement part for the original, problematic radiant proving system.

Thanks, Bill. You're terrific.
