PIECE SIZE
Firewood dries more quickly when it is split. Large unsplit rounds can take years to dry enough to
burn. Even when dried, unsplit logs are difficult to ignite because they don’t have the sharp edges
where the flames first catch. Logs as small as 3” (75 mm) should be split to encourage drying.
Wood should be split to a range of sizes, from about 3” to 6” (75 mm to 150 mm) in cross section.
Having a range of sizes makes starting and rekindling fires much easier. Often, the firewood
purchased from commercial suppliers is not split finely enough for convenient stoking. It is
sometimes advisable to resplit the wood before stacking to dry.

HOW TO DRY FIREWOOD
Firewood that is not dry enough to burn is the cause of most complaints about wood inserts.
Continually burning green or unseasoned wood produces more creosote and involves lack of heat
and dirty glass door. See
Section 5:
Maintaining your wood heating system
for concerns about
creosote.
