Clean Pellet Stove Tips (Ash Away Tool Review for Firewood Pros)
Before we dive into the nitty-gritty of cleaning and the “Ash Away Tool Review,” let’s address a crucial, often overlooked aspect of using wood-burning appliances: allergies.
Introduction: Allergies and Wood Heat – A Personal Note
Living with seasonal allergies has always been a part of my life. But it wasn’t until I started working more intimately with wood – cutting, splitting, drying, and burning it – that I truly understood the connection between wood heat and allergic reactions. Dust, mold spores, and even the wood itself can trigger sensitivities. I remember one particularly harsh winter where I was constantly battling a stuffy nose and itchy eyes, only to realize that the culprit was the improperly stored firewood in my basement. The dampness had encouraged mold growth, and every time I brought wood inside, I was releasing allergens into the air.
This experience made me much more diligent about how I handle wood, both before and after it goes into the stove. Proper storage, ventilation, and regular cleaning of the stove are all essential for minimizing allergens and maintaining good air quality. Now, let’s get into the heart of maintaining a clean pellet stove, including a review of the Ash Away tool.
Understanding the Importance of Regular Cleaning
Pellet stoves burn wood pellets, which are made from compressed sawdust and other wood byproducts. While pellet fuel is relatively clean-burning compared to traditional firewood, it still produces ash as a byproduct. This ash accumulates in various parts of the stove, including the burn pot, heat exchanger, and exhaust system.
Data Point: According to the Pellet Fuels Institute (PFI), a typical pellet stove can produce between 1 to 5 pounds of ash per ton of pellets burned, depending on the quality of the pellets and the stove’s efficiency.
Why Cleaning Matters:
- Improved Efficiency: Ash buildup insulates the heat exchanger, reducing the stove’s ability to transfer heat to the room. This means you’ll need to burn more pellets to achieve the same level of warmth, increasing your fuel costs.
- Reduced Risk of Malfunctions: Excessive ash can clog the burn pot, preventing proper airflow and leading to incomplete combustion. This can cause the stove to shut down prematurely or produce excessive smoke.
- Enhanced Safety: Creosote, a flammable byproduct of incomplete combustion, can accumulate in the exhaust system. If creosote ignites, it can cause a dangerous chimney fire.
- Extended Stove Lifespan: Regular cleaning helps prevent corrosion and wear on the stove’s components, extending its overall lifespan.
Essential Cleaning Tools and Supplies
Before you begin cleaning your pellet stove, gather the following tools and supplies:
- Ash Away Tool (or similar ash removal tool): Designed to efficiently remove ash from the burn pot and other hard-to-reach areas.
- Shop Vacuum with HEPA Filter: Essential for safely and effectively removing ash without releasing harmful particles into the air. A standard vacuum cleaner is not recommended, as it can spread fine ash particles.
- Pellet Stove Brush: Used to scrub the heat exchanger tubes and other surfaces to remove stubborn ash and creosote deposits.
- Scraper: A metal scraper can be helpful for removing hardened ash or creosote from the burn pot and other areas.
- Gloves: Protect your hands from dirt, ash, and potential irritants.
- Safety Glasses: Prevent ash and debris from getting into your eyes.
- Dust Mask or Respirator: Protect your lungs from inhaling fine ash particles.
- Pellet Stove Cleaner: A specialized cleaner designed to remove creosote and other deposits from the stove’s interior. (Optional, but recommended)
- Screwdriver: For removing access panels and other components.
- Owner’s Manual: Consult your owner’s manual for specific cleaning instructions and maintenance recommendations for your stove model.
Step-by-Step Cleaning Procedure
Safety First: Before starting any cleaning, make sure the stove is completely cool and disconnected from the power supply. This is non-negotiable. I once rushed the process and ended up with a minor burn – a lesson learned the hard way.
-
Empty the Ash Pan: The ash pan is located at the bottom of the stove. Carefully remove it and empty the ash into a metal container with a tight-fitting lid. Dispose of the ash properly according to local regulations. Do not use a plastic container as embers can remain.
-
Clean the Burn Pot: The burn pot is where the pellets are burned. Use the Ash Away tool or a similar ash removal tool to scoop out any remaining ash and clinkers (hardened ash deposits). A scraper can be used to remove stubborn deposits.
- Ash Away Tool Review: I’ve found the Ash Away tool to be particularly effective for cleaning the burn pot. Its design allows you to reach into tight spaces and scoop out ash without making a mess. The long handle provides good leverage, and the durable construction ensures it will last for years. However, it’s important to choose the right size for your specific burn pot. Some models may be too large or too small to effectively remove ash.
-
Clean the Heat Exchanger: The heat exchanger consists of a series of tubes that transfer heat from the combustion chamber to the room. Use a pellet stove brush to scrub the tubes and remove any ash or creosote deposits. Then, use the shop vacuum to remove the dislodged debris.
- Technique Tip: When cleaning the heat exchanger, work from top to bottom to prevent ash from falling back onto previously cleaned areas.
-
Clean the Exhaust System: The exhaust system vents the combustion gases outside. Over time, creosote can accumulate in the exhaust pipe and chimney, posing a fire hazard.
-
Important Note: Cleaning the exhaust system is a more involved process that may require specialized tools and expertise. If you are not comfortable performing this task yourself, it is best to hire a qualified chimney sweep. I’ve seen too many DIY attempts go wrong, resulting in damaged equipment and potential safety risks.
-
DIY Cleaning (If you’re comfortable and equipped): Disconnect the exhaust pipe from the stove and use a chimney brush to scrub the inside of the pipe. Use the shop vacuum to remove any dislodged creosote. Inspect the chimney for any signs of damage or excessive creosote buildup.
-
-
Clean the Combustion Chamber: Use the shop vacuum to remove any remaining ash and debris from the combustion chamber. Pay particular attention to the areas around the burn pot and heat exchanger.
-
Clean the Air Intakes: Pellet stoves require a steady supply of air for proper combustion. Make sure the air intakes are clear of any obstructions, such as dust, lint, or pet hair.
-
Inspect and Clean the Blower Motor: The blower motor circulates air through the stove, distributing heat to the room. Over time, the blower motor can accumulate dust and debris, reducing its efficiency.
-
Caution: Before inspecting or cleaning the blower motor, make sure the stove is completely disconnected from the power supply.
-
Cleaning Procedure: Remove the access panel to the blower motor. Use a soft brush or vacuum cleaner to remove any dust and debris from the motor and fan blades.
-
-
Reassemble the Stove: Once you have cleaned all the components, carefully reassemble the stove. Make sure all access panels are securely fastened.
-
Test the Stove: After reassembling the stove, plug it back into the power supply and test it to make sure it is functioning properly. Observe the flame pattern and listen for any unusual noises.
Frequency of Cleaning
The frequency of cleaning depends on several factors, including the quality of the pellets you use, the amount of time you operate the stove, and your personal preferences.
General Guidelines:
- Daily: Empty the ash pan and clean the burn pot.
- Weekly: Clean the heat exchanger and combustion chamber.
