Distance to non combustible walls
By non combustible one means a non load-bearing wall of solid
brickwork/concrete.
Contact your local building authority regarding restrictions and
installation requirements.
4.4 Ceiling
There must be a minimum distance of 1200 mm to a combustible
ceiling above the fireplace.
4.5 Chimneys and flue pipes
• The fireplace can be connected to a chimney and flue
pipe approved for solid fuel fired appliances with flue gas
temperatures specified in «2.0 Technical data».
• The chimney's cross-section must be at least as big as the
flue pipe's cross-section. See «2.0 Technical data» when
calculating the correct chimney cross-section.
• Several fireplaces can be connected to the same chimney if
the chimney's cross-section is sufficient.
• Connection to the chimney must be carried out in accordance with
the installation instructions from the supplier of the chimney.
• Before making a hole in the chimney the fireplace should be
test-mounted in order to correctly mark the position of the
fireplace and the hole in the chimney. See fig. 1 for minimum
dimensions.
• Ensure that the flue pipe is inclined all the way up to the
chimney.
• Use a flue pipe bend with a sweeping hatch that allows it to
be swept.
Be aware of the fact that it is particularly important that
connections have a certain flexibility in order to prevent
movement in the installation leading to cracks.
N.B. A correct and sealed connection is very important for the
proper functioning of the product.
Recommended chimney draught: «See 2.0 Technical data». If the
draught is too strong you can install and operate a flue damper
to control the draught.
In case of chimney fire:
• Close all hatches and vents.
• Keep the firebox door closed.
• Check the loft and cellar for smoke.
• Call the fire service.
• Before use after a fire an expert must check the installation
in order to ensure that it is fully functional.

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
By 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 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 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 55 cm. Jøtul F 600
has a nominal heat output of 9,5 kW. This is equivalent to a
consumption of approximately 2,8 kg of quality firewood per
hour.
Jøtul F 600 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:
