Even if you aren’t using a home chimney anymore, you need to vent it at the top and bottom to allow for continuous airflow. A blocked-up chimney is still a chimney, so it requires annual maintenance and a professional inspection to ensure its structural integrity is intact. Consult a chimney professional about the ideal timing for venting an unused chimney.

Yes, you can put a freestanding one in a corner if you’re tight on space. Because pellet stoves don’t get as hot as other types of wood stoves, there only needs to be 3 inches of clearance from the wall on each side. Placing it in a corner should not impact the ventilation—you’ll still need to follow safety precautions by not installing too close to a window. Typically, it’s 4 feet from a window or 18 inches if the stove uses an external air source for combustion. Always check the owner’s manual for specific instructions.

Both vented and ventless gas fireplaces have pros and cons, and the best choice depends on your needs and preferences. A ventless fireplace may be a good option if you do not have a chimney, but you should check local regulations as they are banned in some areas, such as California. On the other hand, if anyone in your household has allergies, asthma, or other respiratory sensitivities, a vented fireplace is a better choice for health and air quality.

A quality pellet stove that receives proper maintenance can last between 15 and 20 years, while most will last at least 10 years. The exact lifespan depends on factors like frequency of use and how well the stove is cared for. Proper maintenance—such as periodically cleaning the vents, vacuuming the ash pan, and refreshing the pellets as needed—can significantly extend its life, making it a worthwhile long-term investment.
