I have never been exposed to this brand before so my wisdom with this is a rookie. The manuals are dated from 1992 and the Company is out of Bend Oregon that may be defunct or acquired by another company. The grill, oven, stove, smoker is made of stainless steel. The dimensions are basically 12x12 inch grill surface at 16 in height and when the oven component is used it sits at 2.5 feet in height with three racks or you can remove the racks and use the fowl stand shown in the pics. The system itself is very easy to setup and with foil liner makes for easy cleanup. The manual states that Pyromid made 4 types, 8, 12, 15 and 18 inch systems at the time. I believe the system I have is the 15 inch or 18 depending on how you measure. When using charcoal, the heat grate has slots and you stand up the charcoal in the slots. If anyone needs our wants pics of the manuals please ask and I will post em. I see this system for sale but very few reviews.
