Pellet Stove Product SamplePellet stoves are efficient heaters, but they need proper maintenance more than traditional furnaces and woodstoves.

Pellet stove maintenance can be costly, which warrants adequate cleaning to extend longevity.

Proper pellet stove cleaning and maintenance increase its longevity since it doesn’t need repairs more often.

You should clean your pellet stove every year or before the start of winter when a pellet stove runs for long hours.

If you’re wondering how to clean a pellet stove, this guide will answer all your questions.

Casing Or Outer Body

It is the most significant part of a pellet stove since it holds all other components. Further, it stores the fuel, usually as pellets, and provides storage for at least a day’s burning.

Cleaning the outer body prevents your pellet stove from rusting. But if you notice any rust accumulating, you can scrub using sandpaper.

Burning Pot

The burning pot is in the combustion chamber where pellets are compressed. It acts as a carburetor for the stove since it mixes the air and fuel, creating a flame.

Use an ash vacuum cleaner to clean the ash pot and remove the ashes. Remove the burning pot from the compartment and clean the holes using a metal cleaning rod.

Looking Glass

You can know whether the fire is burning well through the glass. Looking glass is typically self-cleaning, but if you want to know how to keep the glass clean on a pellet stove, you can use glass cleaners monthly.

Alternatively, you can use old newspapers or water and vinegar to clean. That will allow you to remove the accumulated dust, soot, and any other substance.

Venting

Venting removes waste products from a pellet stove. Venting occurs through the walls or the roof of a house.

It requires regular cleaning to remove creosote, which may become sticky, damaging the interior of the pipes.

How To Clean A Pellet Stove (Guide For All Parts)

You can use the following for overall pellet stove cleaning:

  • Vacuum – To remove ash
  • Vinegar and Water – For general cleaning
  • Wire brush – For rust removal
  • Dry Cloth – To clean stoves not made of cast iron.
  • Brush – To clean different areas of the stove.
  • Screwdriver – To open different parts of the stove.

Cleaning The Body Casing (Outer Side)

The body casing cleaning depends on the materials your pellet stove is made of, and you should clean it at least twice a month.

Step 1

First, use your wire brush to take out rust, if any. The rust may accumulate if you have taken some time to clean your pellet stove—that’s why it is essential to clean your stove at least once a month.

Step 2

In this step, you can apply some force and use sandpaper. But it applies if you have not taken the rust off for some time. Ensure you scrap all the places that are damaged bit by bit to remove all the rust.

Step 3

If the dirt is from ashes, you can use a damp cloth. Have a spray bottle where you can put a mixture of water and vinegar. The ratio should be 2:1. Spray directly on the pellet stove, give it some time, and then wipe it off with a dry cloth.

Cleaning The Ashes Of Burn Pot

Always use an ash vacuum to clean the burn pot at least weekly.

Step 1

Open the door.

Step 2

Vacuum your burn pot using an electrical ash vacuum. The vacuum will remove all the ashes from the upper part of the stove. I recommend that you use an ash vacuum since it is safe.

Step 3

Clean the pothole using a cleaning rod. Remove it from the compartment for easier cleaning.

Note: Pellet stove manufacturers provide you with a cleaning rod.

Step 4

Clean the burn pot sit using the ash vacuum. The burn sit is where you place the burn pot, and so most of the time, it can get ash droppings.

Step 5

The last step is to assemble all the compartments.

Cleaning The Pellet Stove Auger

Learn how to clean your pellet stove auger by following these steps.

Step 1

Ensure that there is no sawdust built-up on the hopper for easier cleaning. You can do this by burning all the hoppers.

Step 2

Use your vacuum to remove any fuel from the hopper to make the auger easier to clean.

Step 3

Use some oil to apply on your auger, auger pipe, and hopper. You should do this after the stove is cool enough to do so.

How To Maintain A Pellet Stove (For Better Operation And Longevity)

The best way to have your pellet stove last long is to focus on proper maintenance. Suppose you’re new to understanding how to clean a pellet stove. In that case, you should have an appropriate maintenance routine, involve a professional every year to clean the pipes, venting system, and ash traps.

Consider these tips:

  • Avoid Using Low-Quality Pellets
    Low-quality pellets form soot which can be harmful to your stove. Ensure your pellets don’t have multiple fillers and glues since they create smoke and ashes. For this reason, the Pellet Fuel Institute (PFI) started a quality assurance program for pellet manufacturers to meet specific standards.
  • Service Your Pellet Stove Every Autumn
    Do this with the help of a technician who will check whether your stove is operational or has dust or needs a repair on these areas: auger, wiring, switches, igniter, etc.
  • Soot Sweep Regularly
    It’s best if you can sweep weekly because that will remove any soot clogged on the stove. That saves a lot in terms of heat transfer rate.
  • Check Ash and Dust Content Regularly
    Make this a routine so that you can identify if the pellets are burning up completely. If they aren’t, there will be excess sawdust which is not suitable for your stove.
