no.

All gas ranges have had unvented ovens and
top burners for all time, and most people know enough
to have the air adjusted if there is much red or orange
or yellow flames.
With pure blue flame they are considered safe,
but it is assumed they are not used constantly.

Most of the unvented heaters are not very
large, usually less than 20,000 BTU/hour.

My vented heaters are 75,000 and 35,000
BTU/hour, and Cozy also sells them with propane
jets, but they are all vented.

Gas water heaters do kill people, but it
usually takes both a blocked vent and an incorrect
air setting to do that.
All gas appliances must have a way to
adjust the air induction, and if any red, yellow or
orange flame is seen, have somebody that knows
how adjust it.

But any over 20,000 BTU/hour should
probably be vented, especially in rooms where
people sleep.
My heater instructions state how much
of an opening is required for fresh air to enter.
