Commercial Use Only means there are none of the "safe guards".
There is usually a "HOT PLATE at the front edge that will be in the 500 f to 600 f heat range.
This edge is for setting pans that are needed to be preheated or to keep a finished dish hot for the few minutes or seconds needed to get the rest of the order set to go to the expediter (usually the head chef).
There will sometimes be a flat iron side to the stove top as well as the hot plate.
Ovens will be
side by side one larger than the other and usually not convection.
There aren't any clocks, timers, etc. All the nobs will be along the front just above the oven doors.
There won't be a back "splash" apron either.
They will all be set up for natural gas with a one inch inlet instead of the 1/2 to 3/4 inch home style gas inlet.
There are many brands of "commercial" stove makers that make models that look like a commercial unit but have the nice home style features and safety items like no up front hot plate.
Wolf, Vulcan, Viking, Garland are top of the rack units and they all make home owner models as well as commercial kitchen models.
My wife (licensed chef for 30 years) likes Garland and Vulcan I too was trained (apprenticeship) as a chef and the kitchens I worked in had either Garland or Viking models which I liked using but my last gig as a chef had Vulcans and Wolf (the wolf was crap compared to the Vulcan).
All can be converted easily to propane by changing out the orifices.
