No. Even if there's a malfunction, the pilot lights are cleverly designed so that if the oxygen levels in the room lower, they go out. But normally gas burns pretty much completely, only leaving a bit of moisture in the air. It's said that after many, many years you can detect a darkening in a room from unvented gas. But by then most people would have painted and replaced furniture anyway.
This thread is bouncing all over the place though, straying from units that require no electricity at all to those that require some. e.g. Any unit without a pilot light will obviously require power (or mechanical assist) to ignite. All pellet stoves require power for the feed mechanism to operate. I think what threw us is when Betty said she has week long power failures all the time, and she doesn't want a whole house generator, so she just hunkers down and toughs it out in her solar house. That's such a rare combination of circumstances in the U.S. it's left us all confused.
