Running new circuit cable behind finished wall

I need to run 10 guage nmb to a heater that is located about 6 to 7 feet down a finished wall. THis wall sits a few inches away from the cement foundation and I can get between the wall and foundation from a utility room that is unfinished. Can I just use fish tape and pull the wire this lenght with a staple at each end? I know it should be supported about every four feet with staples but in this case I can not do that. Would I be better off if I slip a piece of conduit down the wall fasten it at both each end so that the wire is supported in the middle?

No staples are required for wires fished in a finished wall.

So its ok for the wire to "hang" a bit behind the wall? To clarify it wont be fished through holes bored in the studs it would be fished along the back so nothing is supporting the cable. Would it be better to have it lay on the ground behind the wall than to hang?

Thanks again.

Yes it can hang behind the finished wall. You only need to staple the cable where you can reach when fishing into a finished wall.
