5.0 Use

5.1 Choice of fuel
Always use quality wood. This will give you optimal results, any
other fuel may damage the fireplace.
5.2 Jøtul's definition of quality
firewood
With good quality firewood we mean logs of, for example, birch,
beech, and pine.
Good quality firewood should be dried so that the water content
is maximum 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 should be covered on top 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 of 1 kg of firewood 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 birch will provide less energy (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 firewood (0% humidity) produces
about 5 kWh, while firewood with a humidity 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.
• The fireplace emits little warmth.
• Risk of chimney fire as a consequence of accumulation of soot
in the fireplace, flue pipe and chimney.
• The fire may die out.
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
This may harm the product and pollute the atmosphere.
N.B. Never use combustible liquids such as petrol, kerosene, red
spirit or similar to start the fire. This may cause harm to both
yourself and the product.
5.3 Log length and amount
The maximum length of logs to be used is 40 cm. Jøtul
F 602 has a nominal heat output of 6.0 kW. This is equivalent to
a consumption of approximately 2.0 kg of logs per hour.
The Jøtul F 602 is a product that uses an extra air supply to enable
the afterburning of hazardous gases and particles. It is important
that the system is used correctly.
Another important factor for proper fuel consumption is that the
logs are the correct size. The size of the logs should be:
Kindling:
Length: 30-40 cm
Diameter: 2-5 cm
Amount per fire: 8-10 pieces
Firewood (split logs):
Recomended length: 30-35 cm
Diameter: Approx. 8- 12 cm
Intervals for adding wood: Approx. every 45 minutes
Size of the fire: 1,5 kg
Amount per load: 2 pieces

5.4 First time use

Before lighting the fire, spread a layer of sand in the bottom to
protect the base plate. It should cover the top of the ribs. One
may also use ashes instead of sand.
• Light the fire as described under «5.5 Daily use».
• Light the fire for a couple of hours and ventilate any smoke
and smell from the product.
• Repeat this a couple of times.
N.B. Odours when using the fireplace for the
first time.
Painted products: The fireplace may emit an irritating gas when
used for the first time, and it may smell a little. The gas is not toxic,
but the room should be thoroughly ventilated. Let the fire burn
with a high draught until all traces of the gas have disappeared
and no smoke or smells can be detected.
Enamelled products: Condensation may form on the surface of
the fireplace the first few times it is used. This must be wiped
off to prevent permanent stains forming when the surface heats
up.

5.5 Daily use

The product is intended for intermittent combustion. By
intermittent combustion one means normal use of a fireplace,
meaning that each fire should burn down to embers before new
firewood is added.
Lighting
• Open the vent by moving it to the right (fig. 6D). Use a glove,
for example, when the handle is warm.
• Place two medium sized logs in/out on each side of the
base.
• Crumple some newspaper (or birch bark) between these
and add some kindling wood in a criss-cross pattern on top
and light the newspaper. Gradually increase the size of the
wood.
• Leave the door slightly open until the logs catch fire. Close the
door when the firewood has ignited and the fire is burning
well.
• Check that afterburning (secondary combustion) starts. This is
best indicated by yellow, flickering flames under the baffle.
• Then regulate the rate of combustion to the desired level of
heating by adjusting the air vent (fig. 6D).
Nominal heat emission is achieved when the air vent is open
approximately 25%.
