Gas smell when using oven
I recently moved into a home with a Viking gas range (I believe the range is about 5 years old). I've always had a gas cooktop, but electric ovens, so this is my first experience with a gas oven. When I preheat the oven, there is a strong gas odor. It goes away once the oven is fully heated. Is this normal? It's strong enough that I turn on the vent fan in an effort to get rid of it. Trying to figure out if I should call the gas company out or if this is normal. Thanks.
