So I got a new, unused bouble barrel wood stove in on trade. Looks well assembled. I'm gonna caulk or add fireplace gasket around where the middle legs met the top of the lower barrel. Any tips? I'm also thinking of lining the firebox bottom with bricks. Any suggestions or tips would be appreciated. I'm replacing an old single barrel stove that's on it's last legs but the double wall exhaust pipe is in great shape.
