We acquired a 1979 model Hearthstone stove set#2066 after looking high and low for the oval to round pipe we finally found one but paid through the nose. Looking into the inside we see that there is nothing like a log rack, grate etc. to hold the wood up. Looking in all you see is a floor on the bottom with ribs in it. A dealer told me all you need to to is cover the bottom with sand??? Any pics or help would be so much appreciated, thanks!
