5.0 Operating instructions
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 from a Jøtul I 80 RH is 9,0 kWh. The requirement for
nominal heat emission is 2,9 kg of quality firewood per hour.
The Jøtul I 80 RH 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: Approx 35 cm
Diameter: 2-5 cm
Amount per fire: 8-10 pieces
Firewood (split logs):
Recommended length: 30-40 cm
Diameter: Approx. 8-12 cm
Intervals for adding wood: Approx. every 60 minutes
Size of the fire: 3 kg
Mengde pr. ilegg: 4 stk.

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.
Open the air vent on the door fully by moving the vent all the
way to the right (fig. 5A - 5B).
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. Increase the size of the logs gradually.
Leave the door slightly open until the logs catch fire.Close
the ignition vent when the firewood has ignited and the fire
is burning briskly.
Check that the afterburning (secondary combustion) starts.
This is best indicated by yellow, flickering flames at the air
chamber.
Then regulate the rate of combustion to the desired level of
heating by adjusting the draught vent (fig. 5A). (Use a glove,
for example, when the handle is warm.)
Nominal heat emission is achieved when the air vent is open
approximately 80% (fig. 5A).

5.6 Adding firewood

Each load should burn down to embers before new firewood is
added. Open the door slightly and allow the negative pressure
to level out prior to opening the door completely.
Add the wood and make sure that the air vent is fully open
for a few minutes until the wood has caught fire.
Close the air vent (fig.5A) once the wood has properly ignited
and is burning well. Check that afterburning (secondary
combustion) starts.
N.B. Danger of overheating: the fireplace must never be used in
a manner that causes overheating.
Overheating occurs when there is too much wood and/or air so
that too much heat is developed. A sure sign of overheating is
when parts of the fireplace glow red. If this happens, reduce the
ventilation opening immediately.
Upon suspicion of excessive/poor draught in the chimney, seek
professional help. See also «2.0 Technical data» and «4.5 Chimney»
for information.
