I went and put a deposit down on the stove and measured it, and it is 30 inches. I have no way to quickly measure the hole in the counter, but I must believe it is 31 inches.
It looks like they had electric stove and water heater and converted to gas. So, there is a 3 prong outlet near the gas water heater (looks like the outlet for a window a/c but the house has central air).
And an electrical box near the gas line for the stove.
I was wanting to go back to electric, so I bought an electric stove and like new, Hotpoint, steal, so I can easily sell it, if gas stove is my only option.
Starting a new thread on types of stove plugs to assist the owner of this electric stove.
