There are several maintenance tips you should take to ensure your pellet stove's safety and proper maintenance. You should vacuum the ash pan every week to prevent overflowing and clean the stove and surrounding vents every three to four months. It’s also important to get a professional inspection every year and install a carbon monoxide detector close to your stove. Be sure to dispose of hot ashes in a closed metal container; store it outside, away from the house. Only use the pellets recommended by your stove's manufacturer, and follow any cleaning and maintenance instructions.

It’s possible to clean your chimney by accessing it from the opening above your fireplace, but be aware that this method is messier because you will be pulling loose buildup of soot, ash, and creosote into your fireplace instead of up, out, and onto the roof. While the bottom-up method can cause more of a mess, it’s a good option if you’re not comfortable getting on the roof.

The National Fire Protection Association (NFPA) says that chimneys and their associated elements like fireplaces, vents, or stoves should be cleaned at least once a year before the start of seasonal use. According to the Chimney Safety Institute of America, a chimney should be cleaned when there is 1/8 inch of soot buildup. If there’s more than that, creosote—a flammable byproduct of burning wood—can form and increase the risk of a chimney fire.

Clean the stove, chimney, or vent regularly, and schedule annual professional inspections to ensure safety.
