How to Close the Flue on a Gas Fireplace?

This can cause poisoning, or worse, can lead to a spark-induced structure fire. Luckily, there are some simple steps you can follow to avoid these hazards.

First, make sure you’re using the right kind of damper. Some types of fireplaces have a fancy keep-open device that is very handy. For example, some gas fireplaces are equipped with oxygen depletion sensors that will shut off the gas supply to the flame if the levels of oxygen in the air are too low. You’ll also want to make sure the chimney is lined with rigid foam board, which can help improve the air tightness of the flue. 

Next, you’ll want to check the fireplace’s firebox. Make sure there are no gaps or cracks. Also, be sure that there are no tell-tale smoke stains. In addition, you might want to install a glass door on the front of the fireplace to allow for better ventilation. 

Finally, you’ll need to get your hands on a flue closure mechanism. These may be pull chains or levers. The most common place to find a flue closure system is on the interior front wall of the fireplace. However, you can also find it on the exterior of the fireplace. 

As you’re looking for a flue closure, you’ll want to be sure to wear protective clothing, including work gloves, so you don’t accidentally burn yourself. One of the more recognizable flue closure systems involves a small chain that runs from the top of the chimney to the hearth. Another type of system is a rotary knob that allows you to open and close the flue. 

The best way to learn how to close a flue is to read your owners manual. This is especially important if you have children or pets. There are many gas fireplaces that are incredibly dangerous, and if you use one, you’ll want to take the proper safety precautions. 

A flue is a great way to ventilate your home, but it’s only recommended if you haven’t been using your fireplace in a while. That’s because closing the flue can leave a hot spot in your house that could result in a smoldering fire. On the other hand, keeping the flue open will help you retain the heat and warmth from your fire. 

Of course, you don’t want to be left out in the cold. Many states require flues in order to protect residents from dangerous fumes. And if you live in a warm climate, it’s a good idea to leave the flue open in the winter. It will also let you see your fireplace from a higher perspective. 

If you’re still not sure how to close a flue, there are several easy ways to do it. While it might seem like a hassle, the safety benefits are well worth the extra effort.
