I need to know how to safely move my new Kenmore Elite slide-in range away from the wall

I just bought a new Kenmore Elite 4109-3 range. Sears installed it, but it won't push all the way back into its space. It's out about 1 1/2 inches out from where it should be up against the trim board. I think the electric block (it's a bi-fuel) is in the way and I will need to have my electrician move it. The problem is this. It is a very heavy stove. The manual says not to move it by it's cooktop. What it doesn't say is HOW to move it without hurting the stove. I have been through about 5 layers of Sears support. They all say have the installer come back. We have one installer here for the entire state, and it took me 3 weeks (and a call to the store manager) to get him here in the first place. I'd rather have my own people do the work, but I have to know how to move the stove so they can get behind it.
