Gas Fireplace: Open or Closed Flue?

For the first time this year, I decided to light my fireplace.

Honestly, the cold weather made the decision for me. Admittedly, my house seems to be a bit drafty.  The thermostat can be set to 68, and for a while, it'll be comfortable.  Then, all of a sudden, it's cold.  Not just cooler to the point of prompting the heat to come on, but sometimes it seems like an extra little boost is necessary.

Most of the time, we'll supplement the heat generated by central unit by bundling up in blankets, especially when spending the day leisurely. But today, it felt just like the perfect time to fire up the fireplace.

Now, my fireplace is gas. There are decorative imitation logs as well. With all of this in mind, it's important for me to know the safety precautions which need to be taken to operate the fireplace.

It goes without saying that a wood-burning fireplace needs to have an open chimney, but does a gas fireplace?  Turns out, it depends on what kind of fireplace is in the home. More information.

To be on the safe side, I open my flue.  If you're unsure about yours, get a professional opinion.
