7.0 Choice of fuel

Always use the specified fuel. (Fuel type is described in 

«2.0 

Technical data»

 in the installation manual for each product). 

This will give you optimal results. Use of other fuels may damage 

to the product. 

7.1 Jøtul’s definition of quality firewood 

By good quality firewood we mean logs of, for example, 

birch, beech and oak.

Good quality wood should be dried so that the water content is 

approx. 20%.

To achieve this the wood should be chopped at the latest in late 

winter or early spring. It should be cut and stacked so that air 

circulates around it. The stacks must be protected so as to avoid 

absorbing excessive rainwater. The logs should be taken indoors 

in autumn for use during the winter season.

The amount of energy obtainable from 1 kg of wood varies very 

little. On the other hand the specific weight of the different kinds 

of wood varies considerably. As an example, a certain volume of 

fir will provide less kWh than the same volume of oak, which has 

a higher specific weight. 

The amount of energy produced by 1 kg quality wood is about 

3,8 kWh. 1 kg of completely dry wood (0% moisture) produces 

approximately 5 kWh, while wood with a moisture level of 60% 

produces only around 1,5 kWh/kg.

Consequences of using damp wood may include:

•  Appearance of soot/tar on the glass, in the fireplace and in 

the chimney.

•  Fireplace will give less heat.

• 

Risk of chimney fire as a consequence of accumulation of soot 

in the fireplace, flue pipe and chimney.

•  The wood is difficult to light and the fire can die.

Be especially careful never to lay a fire using any of the following 

materials:

•  Household waste, plastic bags, etc.

•  Painted or impregnated wood (highly toxic).

•  Chipboard or laminated boards.

• Driftwood 

(seawater).

This may harm the product and pollute the atmosphere.

N.B. Never use combustible liquids such as petrol, kerosene, 

alcohol or similar to start the fire. This may cause harm to both 

yourself and the product.

7.2 Jøtul’s definition of quality coal

By good quality coal we mean mineral coal according to 

the specifications in EN 13240, table B.2. (Briquetted fuel 

for closed appliances.) 

For example use: Phurnacite. 

7.3 Fuel size and amount

Jøtul’s products are developed to have excellent combustion.  

An important factor for good combustion is that the fuel is the 

correct size.  The size and amount of fuel should be as described in 

«2.0 Technical data» in the installation manual for each product.

7.4 Intermittent/continuous 

c

ombustion

Intermittent combustion

Most of Jøtul’s products are designed for intermittent 

combustion. (See installation manual 

«2.0 Technical data«

for each product).

Intermittent combustion in this context means normal use 

of the fireplace, i.e. fuel is added as soon as the fuel has 

burnt down to a suitable amount of embers. 

Continuous combustion

Some products are suitable for continuous combustion. (See 

installation manual 

«2.0 Technical data«

 for each product).

Continuous combustion in this context means that a 

fireplace can burn overnight without having to relight 

the fire.
