moisture. Test the moisture content periodically to ensure the proper dryness.

There are many varieties of corn grown around the world. Each variety has unique characteristics including the shape and size of the kernel. The stove will burn more consistently with a small to midsize kernel corn. If the kernel size of the corn varies greatly or if you switch sources frequently, you will get a less consistent burn. Therefore, purchasing corn from the same source will help achieve a more consistent burn.

WOOD PELLETS

As with corn, find a consistent pellet supplier. Pellets will vary in content and burn characteristics from supplier to supplier. A consistent supply of pellets will result in a more consistent and efficient burn.

Check the pellets for foreign objects.The stove warranty will not cover damage done to the stove due to foreign objects in the fuel supply.

Store the pellets in a dry place to prevent them from absorbing added moisture.

To decrease sawdust buildup, the hopper will need to be vacuumed out after every 6-8 bags of wood pellets or more often if the pellets are poor quality. You may have to screen each bag of pellets if sawdust becomes a problem.

The press wood pellet is generally produced out of wood waste such as sawdust and shavings. The raw material is dried, mechanically fractioned to size and extruded under intense pressure into pellets. In the process the raw material is compressed approximately 3.7 times. High quality wood pellets have a moisture content of 3 to 7% and are hydrophilic.The shiny surface of the pellet is caused by partial plasticizing of the lignin in the wood due to high pressure and the evaporation of the water soluble compounds during the production process.The surface protects the pellets from absorbing any significant amount of airborne water vapor under normal atmospheric conditions. However, wood pellets need to be protected from direct water penetration. If exposed to water droplets, from condensation, they will gradually decompose and loose their effectiveness as a fuel. The decomposition involves expanded volume and over time a gradual chemical breakdown.

The natural wood pellet is the woody remains of cherries, edible nuts and any other locally used woody plant that has been classified by the pellet distributor as “natural wood.” It should be comparable in size to the press wood pellets which are 1/4 inch to 5/16 inch diameter and about 3/4 inches long. The natural wood pellet should contain less than 10% moisture.
