Wood fireplace inserts are stoves made of cast iron or other strong metal casing that utilize combustible materials that coming from wood or wood products. They are unlike their traditional firewood fireplace counterparts in that these are designed to burn fuel at far higher efficiency rates. This is especially wood pellets contrary to natural wood pieces and logs that the traditional wood burning fireplaces burn. There are different flammable materials, liquids, and gases (compressed) that can be used as fuel in different home heating appliances. The Napoleon wood burning fireplace insert specifically burns combustible materials made from wood chippings, or other parts of natural wood.
There are two types of materials associated with combustion in wood fireplace inserts; there are those that are combustible while others are completely incombustible under normal burning conditions of heat and pressure. Materials made of wood or surfaced with wood, or made from compressed paper, or form plant fibers, or made from plastics, or any other material that has the capacity to burn at normal conditions of heat and pressure, whether made to have plaster or without plaster; or made flame-proof or not, all fall into the category of combustible solid materials. Some of these have been designed to work with the different varieties of wood fireplace inserts. The other type of materials is the non-combustible ones; and these will not ignite and burn under normal burning conditions. These are materials made exclusively of steel, cast iron, tiled materials, bricks or stones, glass, slate or plasters; or even the combination of all or some of the above are all classified as non-combustible materials. Some of the non-combustible materials are further classified as non-combustible sealant materials that are used as fillings or mortar. Non-combustible materials are never to be used within the Napoleon wood burning fireplace insert. This is to ensure that safety at its best is maintained.
Unlike the wood fireplace inserts, dry seasoned wood is the best source of fuel for the traditional conventional wood burning fireplaces. This is because completely dry and fully seasoned wood logs gives excellently efficient fire that minimizes all chances of creosote formation which itself is a hardened crust-like substance that forms from tar in wood and which accumulate in vents and chimneys. Creosote could ignite causing fire accidents. Though well seasoned wood may be said to have a high degree of efficiency, it may not make wood burning fireplaces exceed the efficiency of, say, the Napoleon wood burning fireplace insert. Again, it is a lot of hassle trying to get seasoned wood with the right amount of moisture content and buying unseasoned wood, on the other hand, is a waste of energy and resources.
In the event that a Napoleon wood burning fireplace insert is being used, it is always advisable to utilize the kind of fuel that the manufacturer has recommended. This is because there are many types of materials that can be said to be combustible but would end up causing danger if used with such a wood burning fireplace insert.
