What goes up the chimney down, but can't go down the chimney up?

Question

It goes up and I go down, it is dazzling and blazing hot. If you look right at it, your eyes will wish you had not. It rises and it sets in different directions, when you stare at it directly there will be some spots in your vision. It is huge and mighty, glorious and bright, it makes everything beautiful from dawn til’ night.

Answer 1

the answer must be an umbrella.
An umbrella is thin and narrow when it is down, so it can fit through the narrow opening of a chimney.
And when an umbrella is up, it is too large to fit through the same narrow opening.

so answer is 'UMBRELLA'.

Answer 2

Is it Smoke................
or Sunlight
