    Hello
    This burnpot similar to it not the same as US Stove 5660 steel burnpot and many others, is burned through in the middle of the bottom just below where the hot Igniter air comes in. The Saranac has been out of production for many years and not fully supported anymore. Some parts are still available, but parts like an Auger is no longer available so a small fix like this may help to keep it going longer. :)
    Therefore since I do not like the slats in the bottom, I just got a sheet of 11 Guage perforated Steel with 1/4” holes. Enviro uses 1/4” holes in their high Ash Burnpot.
    Here is the link to the metal

    Burning fuels other than wood pellets, the hole size maybe smaller. You can get it in stainless steel also from metalsdepot.com The Pot is 12 Gauge so 11 is thicker!
    I order a 1 foot by 2 foot sheet so I can fix a lot of pots.
    Anyway, the easiest way to cut it is to just zip it out with a Plasma cutter but those cutters do not like perforated material unless you get a Hypotherm with extended mode.
    So we just put a small piece of aluminum flashing over it to keep a nice arc and cut them both!
    Then just cut out the bottom of the Burn pot and weld the new piece on. Grind and paint for good looks.
    The Plasma cutter when the trigger on the cutter gun is depressed should be 75 PSI to get a good arc and cut.
    Anyone else do this?
