There are several benefits of heating with pellets instead of other fuel types such as gas or oil. Pellets are clean burning, renewable, affordable, and available in most geographic locations. Pellets also give the smell and ambience of burning wood without the cutting, stacking, and splitting of cordwood, making pellets a more convenient option for homeowners.

The pellets used to heat your home are most commonly made from a variety of woods and wood byproducts such as sawdust. These materials are compiled and compacted waste from industries such as lumber milling, wood construction, and sawmills. As a recycled product, pellets are an environmentally friendly energy source for your home.

To ensure that your wood pellets remain intact and in good burning condition, store them in a cool and dry place, protected from weather and high humidity. In most cases, it is best to store your wood pellets indoors rather than outside.

If kept in a cool, dry place away from moisture and humidity your wood pellets should not go bad. If they are improperly stored, or have been exposed to water, they can deteriorate and fall apart. Proper storage ensures that your pellets will last, should you have excess at the end of the season.

If you are trying to decide on a hearth product, there are several things to consider. First, you need to measure the area of the space you are trying to heat. This will help you determine the size of the appliance you need to get the job done. Secondly, you need to look into what venting options are available to you in your current space.

Once you have determined that you can connect your pellet stove with your thermostat, you then want to place your thermostat on an interior wall about 5 feet from the floor. Ensure that you do not place your thermostat in the direct heat path of your stove, or near any windows.

When using any fuel-burning appliance such as a pellet stove or fireplace, soot buildup is perfectly normal.

If you have cleaned out your firepot and you find hard buildup remaining, you most likely have nothing to worry about. This buildup is caused by impurities in your fuel, which means that it is not an issue with the operation of your appliance. Be sure to scrape any hard buildup off your firepot daily as you clean it. To avoid this issue, using a different brand of fuel may be necessary.

Never put any debris or pellets found in the ash pan back into your appliances hopper. This is to ensure your safety. Ash pan debris may contain embers, which could ignite the rest of the fuel in your hopper. Properly dispose of these pellets with the rest of the debris by emptying the ash pan into a metal container featuring a tight fitting lid. Keep this container away from any combustible materials at all times.

This specific problem can have several causes depending on your particular stove model. Whether your appliance is dirty, or your igniter is malfunctioning, you can find more detailed information on this issue and how to remedy it in your product manual.
