Love this fire pit. Comes put together. Sturdy but light enough to move. The tank goes inside but the directions said in one place to have tank away from out when on and another place it shows a picture of the tank inside and says make sure tube is flat and not linked to avoid melting and starting a fire. So we don’t know how it supposed to go. We bought it so the tank could be inside so that’s how we’re using it. The tubing doesn’t get hot when we use it for an hour or two.  We are going to replace the lava rocks with glass and get a glass guard. Puts off a good amount of heat.
