Charcoal:  As the fire progresses and 

most of the gases have vaporized, 

charcoal remains. Charcoal is 

almost 100% carbon and burns with 

very little flame or smoke. Charcoal 

is a good fuel that burns easily and 

cleanly when enough oxygen is 

present. Of the total energy content 

of the wood you burn, about half is 

in the form of smoke, and half is 

charcoal.

Water: Up to half the weight of 

freshly cut logs is water. After 

proper seasoning only about 20% 

of the weight is water. As the wood 

is heated in the firebox, this water 

boils off, consuming heat energy in 

the wood, the more heat energy is 

consumed. That is why wet wood 

hisses and sizzles while dry wood 

ignites and burns easily.

The firewood you use will make an important contribution to successful operation. You will achieve the best performance 

and overall efficiency by burning firewood that has been split, stacked and air-dried undercover from rain for at least one 

year. Burning improperly seasoned or “green” wood can be a frustrating experience leading to poor performance, smoky 

fires and a build-up of creosote. Do not burn saltwater driftwood refuse, rubber tires, etc. Use of improper fuels can cause a 

fire hazard and lead to a premature deterioration of the stove components, voiding the warranty. (See Fig. 7 Understanding 

Combustion.)
Burn dry wood because:
•  it gives up to 25% higher efficiency;
•  it produces less creosote;
•  it ignites faster and smokes less;
•  valuable heat is lost in the fire as it dries out wet wood.

Smoke  (or  flame):    As  the  wood 

heats up above the boiling point 

of water, it starts to smoke. The 

hydrocarbon gases and tars that 

make up the smoke are combustible 

if the temperature is high enough and 

oxygen is present. When the smoke 

burns, it makes the bright flames that 

are characteristic of a wood fire. If the 

smoke does not burn, it will condense 

in the chimney forming creosote or 

exit the chimney as air pollution.
