Why does my gas stove smell like burnt gas when turning on the oven and burners
Have the orifice checked in the gas regulator. The will come with either a natural gas or propane orifice. Depending on what you have in the way of gas, you may need them swapped. The spare orifices are stored with the regulator.

We had the same problem when we moved in to our house. It came with a new stove, the house has propane, but the smell got progressively worse and the oven was sooted up. We called the installer and the came and swapped out the orifices, problem solved.
