I was overwhelmed when I unpacked the box, but the directions were easy enough to follow. Hooking up the tank was quite simple and the openings allow to reach the shutoff valve without lifting the cover. This produces a consistent and very powerful heat. The ignition works really well, and had this producing heat, the very first time. The unit is super solid and still very lightweight. It has tilt wheels to easily move around. It can be mounted if needed, with the included brackets.
