Step 1
Store your pellets in a convenient, dry place where you can stack them flat and leave them alone until you need them. Leaving pellets exposed to the weather or other moisture can weaken them, and frequently moving or jostling the bags can cause pellets to break apart.
Step 2
When you're opening a bag of pellets, lift the bag upright and shake it gently before opening the top of the bag. If possible, let the bag sit upright for a while before you open it. This will encourage dust and broken pellet pieces to sink to the bottom rather than being distributed throughout the pellets.
Step 3
Pour most of the pellets into your stove. When you get near the bottom of the bag, you'll see where dust and small pellet chunks have accumulated. Separate the remaining good pellets from this scrap material. Some people do this by hand using a kitchen colander or strainer, while others dump and sift their pellets through wire mesh or other homemade devices.
