Wood Quality, Testing And Storage - Heatmaster G100 Operation And Maintenance Manual

This heater is designed to burn natural wood only. Higher efficiencies and lower emissions
generally result when burning air dried seasoned hardwoods (15-20% moisture content), as
compared to softwoods or to green or freshly cut hardwoods.
DO NOT BURN:
(1) Garbage;
(2) Lawn clippings or yard waste;
(3) Materials containing rubber, including tires;
(4) Materials containing plastic;
(5) Waste petroleum products, paints or paint thinners, or asphalt products;
(6) Materials containing asbestos;
(7) Construction or demolition debris;
(8) Railroad ties or pressure-treated wood;
(9) Manure or animal remains;
(10) Salt water driftwood or other previously salt water saturated materials;
(11) Unseasoned wood; or
(12) Paper products, cardboard, plywood, or particleboard.
The prohibition against burning these materials does not prohibit the use of fire starters
made from paper, cardboard, saw dust, wax and similar substances for the purpose of start-
ing a fire in an affected wood heater.
Burning these materials may result in release of toxic fumes or render the heater ineffective
and cause smoke.
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 which have been exposed since cutting. When firewood is very fresh, the
bark will be tightly attached.
Keep in mind the diameter of wood you use. Especially with the G100, using wood that is
no larger in diameter than 6" will give you a better, more even burn. For the G200 and
G400 larger diameter wood can be used but do not exceed 8". For anything over 6" diame-
ter it may be best to split the log. Smaller split wood will season faster, burn better and will
be easier to load and stack in the firebox
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 differ-
ent 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.
