Hello again, recently assembled one of those double barrel stove kits. Got an initial fire outside of one of my buildings and it was roaring! Was wondering if anyone has used these and can tell me how to seal gaps. During assembly the legs didn't really match up well with the barrels so there are gaps present at almost all of the connections! Are there any products to seal these or is it really not that big of a deal on these setups? I understand they aren't high efficient airtight systems, but cheap and effective at heating a garage! Thanks!
