WOOD
The quality of your wood fuel can greatly affect the
burning air dried seasoned hardwoods (15-20% moisture
content), as compared to softwoods or green or freshly
cut hardwoods. Typically it takes at least 12 months to
properly season wood. Seasoned wood looks dark, or
gray when compared to green wood – but if you split a
piece of seasoned wood – it's white on the inside. It has
cracks running through each piece, and a lot of little cracks
on the inner rings. Unseasoned wood has a wet, fresh
looking center, with lighter wood near the edges or ends
very fresh, the bark will be tightly attached.
Using a moisture meter to test your wood
You can use a moisture meter to test how wet your wood
is. A moisture meter will measure the moisture content of
a piece of wood by inserting the metal prongs into the
grain of the wood. The moisture content will be displayed.
To get an accurate reading make sure to use a high quality
moisture meter, split the wood and take at least 2-3
readings from different points of the wood
Storing Wood
Store your wood pile under an open ended shelter to
avoid rain and snow buildup on the pile. Keeping 3 sides
open will allow the sun and wind to season the wood. Do
not keep wood in a woodshed or under a tarp in summer
as the moisture that evaporates from the wood will have
nowhere to go.
Loading
Once a hot coal bed is established, pile small pieces
established.
Load larger pieces of wood until the
desired burn time.
Load only what you need for
the next 12-24 hours as
overloading the furnace

door to the second latch point to allow it to vent the gases

are sure it is safe to do so, keeping your face and body

Only open the door long enough to refuel. A door left
