Older gas ovens used a standing pilot light. They would work without electrical power. Really old ones you light with a match. My kitchen has a gas range, the oven uses electical resistance/incandescent ignitors so it won't work without electrical power. The top burners have spark ignitors but of course I can light them with a match.
