Been looking over the stove rebuild instructions today. I see the reburn screen in the instructions, which is gone from my stove. Got me thinking what is the possibility of upgrading this function? Given new materials, in particular the Cat inserts in newer stoves, is there a product made to more effeciently and more durably perform the reburns on this older stove? There is a dedicated exhaust route for reburning with it's own air intake.
