You should never block both the top and bottom of your chimney. Proper airflow is essential because the temperature inside the chimney will still fluctuate as your house warms and cools. Moisture can build up without ventilation, leading to dampness in your walls over time. Blocking the top prevents debris and animals from entering, but the chimney still needs air circulation to avoid condensation issues. Allowing the chimney to breathe maintains the health of your home and prevents long-term damage.

Start by checking the top or side edge of the door. Look for a certification label or metal tag stamped with details like the fire rating and information on the manufacturer. Even if it’s painted over, the tag should still be visible. Next, look along the edges for slim intumescent strips. They’re designed to swell up and seal gaps when exposed to heat. Finally, check if the door closes itself. Most fire doors have a self-closing mechanism, like an overhead closer or spring hinges. If none of these are obvious, contact a fire safety professional to help verify your door. 

Although no heating appliance can be entirely risk-free, a fireplace insert is considered a safer alternative to a traditional open fireplace, thanks to their enclosed design. With a sealed combustion chamber, a fireplace insert effectively reduces the risk of sparks and embers escaping into the room, minimizing the chance of an accidental fire.

Additionally, an insert comes equipped with various safety features, such as tempered glass doors that create a barrier between the flames and the surrounding space. This enhances both safety and energy efficiency by preventing heat loss. As an added bonus, many inserts are designed to meet strict safety standards that ensure proper ventilation and combustion.

In some cases, you can use a fireplace once the insert has been removed. However, before burning a fire, you must have a professional inspect it and the chimney to make sure they're functioning properly and no damage has occurred from removing the insert. That’s because using a fireplace without an insert could create fire hazards due to issues with airflow and heat dispersion, depending on the fireplace design and material. A professional can advise on whether you should make certain repairs or modifications before using your fireplace as an open hearth.
