Use - Jøtul C 21 Manuel D'installation Et D'utilisation

• Set up the product. The product is heavy. Make sure you have
assistance when erecting and positioning it.
• Make sure the flue outlet's centre line is aligned with the
pre-installed flue pipe adapter/flue pipe. Also ensure that
the front or front panels are aligned with the front of the
framing.
If connecting the smoke outlet and flue pipe is difficult due to
limited access, Jøtul has a special adapter (see "9.0 Optional
equipment") available. This adapter may be used to pre-install the
flue pipe inside the fireplace, prior to inserting the cassette. After
inserting the cassette, the adapter can be put in the right position
through the flue outlet.
• Make sure to leave a clearance of 2-3 mm to the framing to
compensate for possible heat expansion.
Replace all the parts that were removed in order to ease the
handling of the fireplace.
4.8 Control of functions (fig. 5)
Always test the service functions when the insert has been set
up. They should move easily and function satisfactorily.

5.0 Use

5.1 Choice of fuel
Always use quality firewood. This will give you optimal results,
and will not cause any damage to the product.
5.2 Jøtul's definition of quality firewood
With 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 that, the wood should be cut during late winter or early
spring, then cut and stacked to ensure proper airing and covered
to prevent it from absorbing 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
birch 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 % humidity) produces
approximately 5 kWh, while wood 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 50 cm. Nominal heat
emission is 6,5 kWh. The requirement for nominal heat emission
is 2,3 kg of quality firewood per hour.
An important factor for proper fuel consumption is that the logs
are the correct size. The size of the logs should be:
Kindling:
Length: Approx 40 - 45 cm
Diameter: 2 - 5 cm
Amount per fire: 8 - 10 pieces
Firewood (split logs):
Recommended length: 35 cm
Diameter: Approx. 8 - 12 cm
Intervals for adding wood: Approximately every 45 minutes
Size of the fire: 1,8 kg
Amount per load: 3 stk.
