I took the chain off,it's really long at a foot or so.i also did not trust the brackets that hold the top down with the weight of a full Gaz cartage.i never had any intention of hanging it up in my small tent where it would be in the way.it seemed to work great at ground level where the heat would rise up and into the tent.i have used a stove in the past to warm up my Baker shelter.
that was a Peak Feather Coleman fuel stove.it put out plenty of heat inside that big shelter but when I turned it off that stove gave off some nasty fumes while the generator cleared out.
that little metal lamp is perfect for the job.
