Halocho #1301 - Covering a chimney on Shabbat

A chimney or exhaust pipe which juts out of a wall, may be covered on Shabbat, since that is considered adding to an existing wall, which is allowed on Shabbat.

A chimney or exhaust pipe which comes out of the roof may only be covered with its lid, if the lid is connected to the chimney or roof by hinges.

If one does not have a hinged cover, then one may not cover the chimney one Shabbat, because one is forbidden to make a roof on Shabbat.

These Halachot apply to Yom Tov also.
