How to Maintain a Pellet Stove

Buy and Use Only Quality Wood Pellets

Three different grades of wood pellets (premium, standard, and utility) are usually found in the market that is suitable to use in a pellet stove. But, among them, only the premium grade pellets are the best to use in a quality pellet stove since very burn clean, produce less smoke and ash(less than 1%). They are well-known for burning clean and complete. Manufacturers of pellet stoves always recommend using specific grade pellets what is recommended on their user manual or website.

Well, we can teach you a simple trick if you have bought a new pellet stove and you don’t select any wood pellet brand yet. Instead of buying a full bag of pellets, you can buy a few small packets of wood pellet that has very good customer reviews to use in your pellet stove for the experiment. Examine these things – how well it is burning? Is it producing less smoke or not? Do all the pellets burn completely?  Try to use different brands of pellets until you find the perfect match fuel for your heating machine.


Top-fed pellet stoves generally require premium quality wood pellets. But you can use low-quality pellets if your pellet stove is bottom-fed.

Store Pellets Perfectly

It is recommended to keep the pellets away from the air and water. That means you have to find a safer place where you can store your wood pellets. We suggest you store it in a drawer, locker, desk, or chest so that they didn’t get in contact with outside air or moisture. Wood absorbs water if you keep it in an open place. furthermore, keeping wood pellets in the open air will degrade the quality of pellets collecting moisture from the air. This increases the quantity of water present in the pellet. The presence of a high volume of water may create greater smoke while it burned in the stove.


Sometimes the bag of pellet stove becomes damaged. You have to cover up the damaged portion of the pellet bag with waterproof tapes.

Don’t store pellets in your living room or bedroom. It may attract the pest or insects. Also, pellet emits a little number of toxic gases (carbon monoxide) when it is stored. Find a safer place outside your home like a garage or you can choose your storeroom for this purpose.  You need to use an exhaust or ventilation fan for safety.

Fill Up the Hopper

The hopper capacity of a pellet stove may be vary depending on the model and brand that you are willing or looking forward to purchasing. You may find a pellet stove has a pellet holding capacity ranging from 50lb-250lb. The bigger hopper can hold more wood pellets. A pellet stove that has a very good hopper capacity needs to replenish 2 or 3 times a week. On the other hand, low capacity hopper needs frequent refilling, maybe you have to fill it once or twice a day and that would be a big hassle since you have to clean the hopper each time you replenish it with wood pellets.

Clean the Front Glass Door

The clean and clear front glass door allows you to see the beautiful and natural fire-burning sights sitting in a chair or bed. Moreover, you can inspect whether pellets burning properly or not.

For example, If the flame of burning wood pellets is orange or some other deep color instead of the usual fire color, that is, bright yellow or white, indicates that there are some internal functional problems with pellet stove. Stop using it if it shows such kind of problem. And, either contact customer service if you have a warranty or hire a professional for service.

Don’t touch the glass while the stove is running. While cleaning the glass, wait for 20 min to cool it down after turning off the fire and power of pellet stove completely. Use a clean towel and good glass cleaner to clean it.  You must clean both inside and outside of the glass. Don’t ever scrape the glass while cleaning. It will definitely harm the glass and have very high chances of glass become blurring.

Clean the Outer Body

Take regular body soap and dissolve some soap in clean water. Make a good solution. Then mix little vinegar in the solution. Take a clean cloth and dip it in the solution. After that, wriggle the cloth until the water in the cloth rises off.  Then, clean the body thoroughly. When you are done cleaning the whole body, take a dry cloth and wipe out the residual water in the body.


Don’t run the stove until the pellet stove become dry completely.

If the body of the pellet stove is made of cast iron, you have to use a vacuum instead of the above solution.

Empty the Ash Trap or Drawer

Regularly check the ash drawer of the pellet stove. Cleaning the ash drawer once or twice a week will be sufficient if your pellet stove ash-bearing capacity is good. Whenever the ash drawer becomes loaded, dumped the ashes in a plastic bag or use an ash vacuum cleaner. You can use your garbage bag for damping. First tip the ash pan in a garbage bag. After that, shake out the ash in the bag.

Clean the Remaining Ash Inside the Stove

Search out the remaining ash that is hidden inside the stove. You must find some ash in the burn pot. Clean it using an ash vacuum cleaner. Don’t ever use a normal household vacuum cleaner or dust buster for this ash cleaning. Ash vacuum is specialized for this work.

Clean the Build-up

When ash melts and becomes hard, it turns into a clinker. Inside the burn pot, you will discover this clinker. You can use a special rake or ash tool or an ash vacuum cleaner to remove them.

Clear Heat Exchanger

Heat exchanger supplies oxygen by bringing the air inside the burn pot and also assist to bring out the warm heat or heatwave produced by the pellet stove. Sometimes shoot build up in the series of tubes of the firebox. Use a wire brush to clean the messes.

Check and Clean Vent Pipe

Hire a certified professional to inspect the vent pipe. If they found something wrong with the pipe, pay them to fix it. Also, expend some money to clean the exhaust pipe of the pellet stove at least once a year.

Empty the Hopper

At the end of the winter season, inspect the hopper for unused pellets. Store the remaining pellets for the beginning of the season. In case you forgot to empty it, the chance of causing rust in the pellet stove becomes very high, as the pellet collects moisture of air during spring and summer.

If you follow the above tips and guidelines, it will make pellet stove safe while using it. Furthermore, above pellet stove maintenance will definitely increase the lifetime of the stove.
