    If a pellet stove is able to show an error log then this can be used to more accurately determine what problems are occurring with the stove.

    We can then use the touch screen to press this triangle and the error log will display all of the recent problems that the stove has experienced. For example, the manual for our own particular model of pellet stove requires us to: Clean the burn pot and the ash tray located within the combustion chamber before each daily fire.

    Clean the ignition and hopper with a vacuum weekly to help prevent the build of pellet dust or ash and in turn help prevent blockages. For more information and to see what maintenance is required for our own stove see our article on pellet stove maintenance. Pellets Using high quality pellets in line with what the manufacturer of a particular model of pellet stove recommends will help to keep a pellet stove burning efficiently and help to minimize the chance for blockages or other problems to occur.

    For example, the manufacturer of our own pellet stove recommends a certain class of pellets to be used, which in our case is Class A1 pellets. Using good quality pellets can help to keep problems to a minimum These pellets meet more stringent standards for ash and moisture content.

    Using lower quality pellets with higher levels of moisture and ash can increase wastage, emissions and smoke production and potentially lead to more problems with a pellet stove such as blockages, smoke or blackening of the glass.

    A pellet stove that keeps shutting off is a sign that the stove requires cleaning, as either the fuel or the air is being blocked from getting the fire. The combustion chamber and hopper should be cleaned thoroughly. A pellet stove shutting off may also signal that a part is worn and needs replacing. The main reasons why a pellet stove is shutting off can include: A blocked air supply. If the burn pot inside the combustion chamber is full of ash and leftover unburnt pellets then this may be blocking the airflow to the fire through the holes in the burn pot.

    A blocked fuel supply. If the stove is unable to deliver pellets properly to the fire then it can be a sign that either the hopper, the auger or the pellet chute or all three are blocked.

    Cleaning a pellet stove will usually help stop a pellet stove from shutting off, in particular the burn pot located in the combustion chamber and the hopper. If your pellet stove has an error log, check it for errors that may help to locate the problem.

    Also be sure to use the correct size of pellets. For example, the maximum length of pellets we can use for our pellet stove is 25mm as using any longer pellets can cause a blockage within the auger and the stove will shut off as a result.

    The holes in the burn pot are blocked up with unburnt pellets or ash. Cleaning the burn pot and the area where the air comes into the combustion chamber can help prevent a fire in a pellet stove from going out due to lack of oxygen. If your pellet stove keeps going out then ensure to take a look inside the hopper for any signs of dust build up at the bottom or within the auger.

    Take a look up the auger chute if possible to see if there are any blockages and clean if necessary. Pellets leaving behind large amounts of ash. A lack of oxygen preventing the fire from burning the pellets properly. Pellets getting stuck in the chute.

    Cleaning the burn pot and ash tray before each fire. Preventing dust from bags of pellets from getting into the hopper and potentially causing blockages. Cleaning pellet dust from the hopper when required. Ensure that the burn pot and the air inlet to the combustion chamber are cleaned thoroughly before each fire to aid in airflow. A pellet stove burning black can be due to either a problem with the pellets or in most cases a problem with the air supply.

    A fire will struggle to burn the pellets and produce more soot if not receiving enough oxygen. A burning black pellet stove can be a result of: The air inlet to the whole stove blocked.

    The air inlet into the combustion chamber is blocked. Replace the door gasket when required to help prevent problems such as blackening of the stove from occurring To help a pellet stove burn cleanly with minimal blackening: Clean the stove at intervals required by the instruction manual, particularly daily cleaning of the burn pot and surrounding areas.

    Have a professional undertake seasonal maintenance on the stove to identify the issue. Ensure that any gaskets are keeping a tight seal and change if necessary. Much like a pellet stove burning black, a smoking pellet stove can be caused by: Poor quality fuel with higher moisture continent leading to poor combustion and smoke being produced. Blocked airflow to the fire either at the inlet to the whole stove or the air inlet to the combustion chamber. A problem with the airflow leaving the stove, such as an issue with the combustion blower or a leak such as through the door gasket.

    To prevent a pellet stove from smoking ensure that nothing is blocking the airflow to the fire such as blocked holes in the burn pot In order to help prevent a pellet stove from smoking: Use high quality fuel that meets certain standards for moisture and ash content. Clean the air inlet to the combustion chamber and the burn pot regularly from any build-up or ash and unburnt pellets. Have a professional check the external air inlet and the door gasket for blockages or leaks as part of a seasonal maintenance, and ensure that the airflow management through the stove is properly calibrated.

    Check any gasket seals for signs of damage and check the flue outlet that connects to the chimney flue system for leaks. The most common place for a pellet stove to leak and a smoke smell to be experienced is from the flue system out the back of the stove, in particular the connection between the flue socket on the stove and the rest of the flue. A smoke smell from a pellet stove may result from a leak between the flue socket on the stove and the chimney flue Another potential location for a leak would be the gasket seal on the door to the combustion chamber.

    Thoroughly clean the stove including the ignition area to help resolve the issue but help from a technician may be required to diagnose any other causes. The ignition in our pellet stove is located below the burn pot and we clean this area before every fire.

    The ignition system right hole under the burn pot of our pellet stove should be clear of ash and pellets to work properly The initial ignition of the pellets is commonly carried out by hot air that is sucked through the fume extractor and around the ignition in the combustion chamber. A fault with the fume extractor combustion blower can prevent a pellet stove from igniting and so may require inspection from a technician.

    Burning low quality pellets that are higher in moisture content can also prevent a pellet stove from igniting properly and so using good quality pellets is always recommended. A pellet stove auger that keeps jamming can be caused by using the wrong size of pellets, too much pellet dust within the hopper and auger or a problem with the motor auger. Cleaning out the hopper regularly can help prevent a pellet stove auger from jamming. The auger in a pellet stove delivers the pellets from the hopper to the fire in the combustion chamber of a pellet stove.

    Reasons why a pellet stove auger can keep jamming and therefore no fuel can be delivered can include: Using pellets that are too large for the particular model of pellet stove. Build-up of dust within the bottom of the hopper and in the auger. The pellet chute is blocked up. The auger motor is worn and needs replacing. Keep the dust out of the hopper when pouring in a new bag of pellets. Have a technician take a look at the hopper motor. A pellet stove blowing cold air is a sign that the convection blower is working but no heat is being generated.

    Pellet stoves need to be cleaned regularly, such as cleaning the burn pot and ash tray daily and cleaning the combustion chamber and hopper weekly as we need to do for our pellet stove. A pellet stove should also be inspected by a technician seasonally for ongoing maintenance of the main components.

    A pellet stove may also blow cold air if the output temperature is set too low. Ensure that the desired room temperature is set higher than the current room temperature. Ensure that the proposed temperature is set higher than the current room temperature or a pellet stove may blow cold air Why Is My Pellet Stove Not Feeding Pellets? Common reasons what a pellet stove would not be feeding pellets can include: An empty hopper.

    Ensure to keep the pellets topped up regularly. The auger is jammed. Clean out the hopper and auger periodically to keep dust accumulation to a minimum, which could cause the auger to jam if dust builds up. The auger motor has failed. A failed auger motor will need replacing. The air inlet is blocked. Check that the inlet for clean air is free from any dust or pellets before each fire.

    Blocked airflow through the stove can prevent the pellets from combusting properly leading to a build-up of unburnt pellets that may look like the pellets are being fed too quickly.

    Ensuring that the combustion chamber, in particular the burn pot, air inlet and ash tray, are cleaned regularly will help maximize air to the fire. The exhaust system of a pellet stove should be cleaned seasonally to promote good airflow The chimney flue for a pellet stove should also be cleaned out annually to prevent airflow blockages.

    For the most efficient and clean burn ensure to use high quality pellets that are low in moisture content and that the air inlet is cleaned before each fire. A blocked air inlet into the combustion chamber. A faulty combustion blower. A blockage in the exhausted air passageway from the combustion chamber to the outside of a home.

    Good quality pellets are more likely to burn all the way through In order to help a pellet stove burn pellets thoroughly: Clean out the combustion chamber before each fire, in particular the burn pot and the air inlet, to maximize airflow.

    Use good quality pellets in line with what the manufacturer recommends. Have a technician go over the stove each season to check everything is working correctly, in particular the combustion blower in the fume extractor, and to clean out the exhaust path. A pellet stove will burn through more pellets when the desired temperature is set much higher than the current room temperature, the outside temperature is very cold or when the stove is attempting to heat an area larger than what it was designed for.

    If we set the desired temperature of the room high then the stove will go through more than double the amount of pellets compared to if the stove was keeping the room at a constant lower temperature. If a room is large or if the starting room temperature is very low then a pellet stove can be burning through a lot of pellets trying to reach the desired room temperature.

    Choosing a high proposed room temperature will make the pellet stove work hard and burn through more pellets as a result Ensuring that a pellet stove is cleaned regularly and well-maintained will help with airflow and the stove will provide the right number of pellets to the fire according for the most efficient fuel to air ratio.

    Lack of sufficient airflow to the fire in a pellet stove can cause the burn pot to overflow with pellets, as insufficient oxygen will prevent the pellets from burning properly. Other reasons why a pellet stove burn pot is overflowing can include: Using poor quality pellets. Build-up of ash or unburnt pellets preventing new pellets from burning properly.

    Incorrect setup for the stove in terms of fuel to air ratio or feed rate of the pellets. A pellet stove will typically produce more ash when the pellets are of lower quality and higher moisture content or when the fuel to air ratio needs adjusting. To help overcome the problem of pellet stoves producing more ash: Use higher quality pellets. We use Class A1 pellets that have a maximum ash content of 0.

    Clean the stove regularly in line with that the manufacturer recommends. A pellet stove will automatically burn hotter as it attempts to bring the room up to the set room temperature from the current room temperature.

    Higher quality pellets will also typically provide a cleaner and hotter burn thanks to lower moisture content.

    All our models have an average sound level of 34dB. In order to make the readings more meaningful, we will use the noise scale on the left and compare them with noises that can be heard in everyday life.

    The observations mentioned in front of the noise level are obviously subjective, as acoustic comfort is specific to each person. They correspond to the feelings of a person who is rather sensitive to noises.

    Important note about dB Sound is the result of an acoustic vibration, a rapid variation in air pressure picked up by the eardrums and transmitted to the brain, which interprets it. Sound is characterized by its intensity, or sound level, which is measured in decibels; its pitch, or frequency, which is measured in Hertz; its timbre, or colour of sound; and finally its duration. Adding 3 dB is equivalent to multiplying the sound intensity by two, while removing 3 dB divides the sound intensity by two.

    So an addition of 10 dB is equivalent to multiplying the sound intensity by ten. Reading notes All the sound readings indicated are taken under the same conditions: identical sound level meter, placed horizontally at mid-height 90cm and 1 meter in front of the stove. The noise level in the home when the stove is off is 31 to 32 dB. There is some variability in taking measurements sound level meter accuracy, non-constant pellet stove noise.

    The sound level of the same stove may vary slightly from one model to another. They are listed in order of importance. Fan noise First of all, the blowing noise. This noise is directly proportional to the fan speed of the motor that propels the heat and can be tiring if listened to for long periods of time. Stoves with natural convection without a blower are therefore at a great advantage from this point of view.

    Conversely, ducted stoves with one or two fans are noisier. In P4 and P5, the very quiet fan will run to heat the room faster. In addition, our extraction motor is located on a cast aluminum smoke snail, which greatly reduces the noise of the smoke snail. The auger moves the pellets from the tank down to the hearth.

    Its rotation is more or less silent. Noise of falling pellets Then, the sound of the pellets as they fall into the crucible from the auger to the hearth. This sound is more or less resonant. The last factor to consider is the sound of the pellets falling into the crucible.

    Other In addition, there are also expansion noises due to temperature changes , flame noises or whistling noises that are normal and difficult to quantify.

    Finally, it is important to install your pellet stove properly: the air intake and an insulated chimney are essential for good results.

    Silent stove

    Using a motor to turn the auger screw at a low RPM speeds up the movement of pellets. The auger motor is usually found at the bottom of the auger screw, and the top of the auger can be seen from inside the combustion chamber through the pellet chute. The auger at the base of the hopper of a pellet stove can be seen here. For the most part, an auger screw is hidden behind a plate that helps keep the pellets inside the auger in place.

    The screw is essentially invisible. When looking up the pellet chute from the burn pot in the combustion chamber, depending on the model of your pellet stove, you may be able to see the top of the auger screw.

    Pellet Stove Augers & Auger Motors (Your Complete Guide)

    With the auger, pellets are conveyed from the hopper to the burn pot inside the combustion chamber. To keep burning and generating heat, a pellet stove fire requires pellets as fuel. As a result, a pellet stove auger feeds the fire with pellets at the fastest possible rate. Using the auger motor, pellets are fed into the top of the auger, where they are discharged into the fire via the pellet chute.

    Parts Of A Pellet Stove Auger The auger and auger motor are the two main components of a pellet stove auger, and the auger is usually covered by a collar. Pellet stove auger motors and collars are typically found in the hopper, while pellet stove augers are typically found at the lower end of the auger. An auger for a pellet stove is made up of the following major components: Auger Collar As the auger rotates, pellets are pushed up the auger by a long screw.

    There is some variability in taking measurements sound level meter accuracy, non-constant pellet stove noise. The sound level of the same stove may vary slightly from one model to another. They are listed in order of importance.

    Fan noise First of all, the blowing noise. This noise is directly proportional to the fan speed of the motor that propels the heat and can be tiring if listened to for long periods of time.

    Stoves with natural convection without a blower are therefore at a great advantage from this point of view. Conversely, ducted stoves with one or two fans are noisier. In P4 and P5, the very quiet fan will run to heat the room faster. If the system becomes clogged with soot or other debris, it can result in the fan making more noise than usual. Bear in mind though, some level of noise is completely normal when burning fuel.

    This is a fairly simple problem to solve, however.

    How to Make a Pellet Stove Quieter

    The fuel system Pellet stoves basically contain an automatic fuel dispenser, which can be a big help. This system uses a motor to drop fuel from the hopper into the burning chamber, which supplies a constant source of heat. See the video below. However, like other moving parts, it can become worn over time, which can result in it becoming louder. The most obvious solution is to replace it, but you can perform a bit of maintenance work to get it running smoothly again.

    You will find over time that your pellet stove could be making more noise than before. This is because, like anything else, it wears, which can have an impact on its function and efficiency.

    So if you think your pellet stove is making a bit too much noise, try some of these solutions. If you have any concerns about noise levels pointing to a bigger problem, however, call in a professional. Tighten everything up Just like anything else with moving parts, pellet stoves can get looser over time.

    Another thing worth considering is that the constant heating and cooling of the metal causes it to expand and contract, which can strain the joins. Go round and check all the screws and bolts, ensuring everything is tight enough. These can be tightened or replaced if necessary, as the motor can wobble itself out of place.

    You could buy something like these workbench feet Amazon which should fit fairly easily onto a stove. They have rubber rings on the bottom to reduce movement and vibration transfer. Alternatively, you could buy some heat resistant foam Amazon and make your own feet pads. This is also a good option if your pellet stove has a wide base and sits directly on the floor.

    The last thing you want is for it to melt and create a fire hazard! Clean and alter the heat exchanger rod Pellet stoves use something called a heat exchanger. This is heated up inside the stove by the burnt fuel, and then it transfers the heat into the room. Over time, the heat exchanger can become clogged with debris and ash, meaning you need to clean it.
