6. Sensible wood burning
When dry wood is burned in a wood-burning stove the following process occurs
(over a period of approximately 1 hour):
· After lighting the log starts to dry and heats up.
· After drying the temperature of the wood rises to approx. 300–400° F
(150 - 200° C) and is converted into volatile gases and charcoal.
· As the wood is gasified a certain portion of the gases produced burn and are
converted into carbon dioxide and water. During this phase the temperature
rises to around 1100 - 1500° F (600 - 800° C) and a plentiful supply of air is re -
quired. If the air supply is accidentally reduced, the flames will be smothered,
but this will not stop the conversion of the wood into gas. The unburned gas
will then flow out into the chimney, causing a nuisance outdoors and build up of
creosote.
· Next the charcoal will burn, which requires very little air supply. Finally, new
wood must be laid on the glowing charcoal cinders.
WARNING - It is extremely important to ensure that you do not over-
heat your stove, as this can cause irreparable damage. This kind of
damage is not covered by the warranty. Extremely high combustion
temperatures can occur when using inappropriate fuel, such as kiln-dried wood,
coal, pressure-treated wood, scrap wood. NEVER USE GASOLINE, GASOLINE-
TYPE LANTERN FUEL, KEROSENE, CHARCOAL LIGHTER FLUID, OR SIMILAR
LIqUIDS TO START OR ‘FRESHEN UP’ A FIRE IN THIS HEATER. KEEP ALL
SUCH LIqUIDS WELL AWAY FROM THE HEATER WHILE IT IS IN USE.
HOT WHILE IN OPERATION. KEEP CHILDREN, CLOTHING AND FURNITURE
AWAY. CONTACT MAY CAUSE SKIN BURNS.
DO NOT STORE SOLID FUEL WITHIN SPACE HEATER INSTALLATION CLEAR-
ANCES OR WITHIN THE SPACE REqUIRED FOR CHARGING AND ASH RE-
MOVAL.
Incorrect wood burning
Too much air supplied to the combustion process causes an uncontrollable fire that
will heat the entire stove very rapidly to an extremely high temperature. This can
happen if you fire with conditions that produce an extra-strong draft in the chimney.
Never fill the stove completely with wood. It is better to heat a stove up slowly. This
will prevent cracked tiles/soapstone, damage to welds and annealing of the iron.
Overfilling the firebox also substantially reduces the useful life of the vermiculite pan -
els, as cracks are more easily caused. The log length should be about 2" (5 cm) less
than the width of the firebox and a maximum 3" (7.6 cm) diameter. Start slowly with
a “normal” fire from the bottom, and slowly build it up to a maximum of three logs.
7. Technical information on wood burning
1 kilo of dry wood is made up of 20% water, with the remaining 80% divided into
60% gas and 20% charcoal. The 60% gas only contains around half the energy
content of the wood, while the 20% charcoal contains the other half. To achieve
optimum combustion, the temperature must reach 1100 - 1500° F (600 - 800° C).
Reload with a few pieces of wood at a time. If too much wood is placed on a layer of
embers, the air supplied will not be sufficient to attain the required temperature, and
the gases will disappear out through the chimney unburned. It is vital to supply air
to the fire immediately after adding fuel, so there are flames in the firebox, and the
gases burn. (Refer to the Refueling section 9 for further guidance).
