Move gas oven away from wall
Old bath towels work very well to protect floors if you double or quad fold them. Lift on the front of the kitchen range unit to get the towel in under the front feet or base.

Then slide out the range unit the few inches needed. It can actually be helpful to have one person pulling out on the top back of the range (which transfers the weight of the unit onto the front feet or base) whilst at the same time have another person tug on the end of the towel stack to help nudge the range out from the wall.

When you have the unit pulled out is also a good opportunity to inspect and clean the area behind the range.
