wiring a oven with 4 wires to home service with 3 wires
If I am reading this right, by "home service" you mean your range receptacle has three prongs, and three wires with no ground wire supplying the receptacle.

If that isn't the case - if you have a ground wire / ground prong on the receptacle - you do NOT want that jumper strap connected!  

That picture is from this article:
