The quantity of firewood determines the heat emission - the more heat you require,
the more wood you should add at each refueling.
Types of fuel and heating values
All the stoves are constructed and approved for burning wood.
Combustion involves conversion of the fuel from solid form into gases, water vapor
and charcoal. The heating value is an expression of the content of combustible
gases - stated in kcal/kg. All wood has roughly the same heating value per kilogram.
The lighter the wood, the more that must be used to achieve the same heating value
as with a heavier species of wood.
Type of wood Dry wood - Lbs./ft3 (Kg/m3) Compare to beech
beech and oak 36.2 (580) 100%
Ash 35.6 (570) 98%
Maple 33.7 (540) 93%
birch 31.8 (510) 88%
Mountain pine 30.0 (480) 83%
Fir 24.3 (390) 67%
Poplar 23.7 (380) 65%
As mentioned, air-dried wood contains around 20% water, corresponding to a heat-
ing value of approx. 4 kWh/kg equivalent to approx. 3440 kcal/kg (1kW = 860 kcal.)
WARNING! NEVER burn impregnated wood,
painted wood, laminated plastic, plywood, chip-
board, refuse, milk cartons, printed matter or
similar. Use of such materials will invalidate your
warranty, as this may emit toxic, corrosive and
hazardous fumes when burned. They may also
cause a build-up of the toxic gas dioxin, which is damaging to
the stove and the environment.
Fuel
Recently-felled wood contains 60-70% water and must therefore be seasoned be-
fore it can be used in a wood-burning stove. It must be cut, split and air dried, and
must contain no more than approx. 25% water before use. This equates to the wood
being left in the open for approx. 1 year - covered only to protect against rain.
It is very important to always use pure, dry wood. Damp wood requires a lot of air for
combustion, as extra energy in the form of heat is needed to dry it out. Heat emis-
sion is therefore minimal. When wood is burned slowly, it
produces tar and other organic vapors, which combine with
expelled moisture to form creosote. The creosote vapors
condense in the relatively cool chimney flue of a slow-burn -
ing fire. As a result, creosote residue accumulates on the
flue lining. When ignited, this creosote makes an extremely
hot fire. The chimney and chimney connector should be in -
spected at least once every two months during the heating
season to determine if a creosote buildup has occurred. If
creosote has accumulated, it should be removed to reduce
the risk of a chimney fire.
