hey guys, Any opinions on burning pallets for kindling? And on another note...I noticed a couple drips of h2o very very slowly running down the interior 2 foot of class a chimney last nite durning a rain. So I checked up above and it seems the caulk that was around the storm collar is cracked, broken, and missing. so I definatly need to recaulk. Is there a special caulk I need to use for this. I know it shouldnt get too hot. but it probly at least gets warm rite? Thanks guys.
