Tips For Good Fuel
Firewood should be cut, split, and stacked in an open area in the early spring to be ready for burning the next heating season. Very hard woods like oak may take longer to season, and seasoning in damp maritime climates may take a little longer than the summer months.
The firewood pieces should be cut to a consistent length, about 75mm (3 inches) shorter than the largest horizontal firebox measurement.
Firewood should be split into a variety of sizes, ranging from about 75mm (3 inches) to no more than 150mm (6 inches) across the largest cross-sectional dimension.
Stack the firewood on rails or poles to raise it slightly off the ground. Separate the rows by at least a pace or two to allow air circulation to carry away moisture.
Any wood species can be burned, although some are less desirable because they are hard to split or have sticky sap in their bark.
Scrap lumber and packing skids can be burned if the pieces are not painted or coated.
