Getting back to a serious answer,
I think Franco's answer is the most likely as it gives the stoves more flexibility for placement, therefor greater chance of number of units that could be sold.
I know it's done that way with a lot of wood stoves. I had to pay extra for the "leg kit" for my wood stove. It was advertised as being able to be used either as an insert, or by just adding the optional leg kit, it becomes a free standing stove. . . . if you like cleaning out ashes while on your hands and knees. The legs are still too short for my old back !
Why wouldn't it make sense for coal stoves too ???
