5.4 Adding firewood
Stoke the stove frequently but only add small amounts of fuel
at a time. If the stove is filled too full, the heat created may
cause extreme stress in the chimney. Add fuel to the fire in
moderation. Avoid smouldering fires as this produces the most
pollution. The fire is best when it is burning well and the smoke
from the chimney is almost invisible.
If there is insufficient burning material in the firebed to light
a new fuel charge, excessive smoke emission can occur.
Refuelling must be carried out onto a sufficient quantity of
glowing embers and ash that the new fuel charge will ignite
in a reasonable period. If there are too few embers in the fire
bed, add suitable kindling to prevent excessive smoke.
5.5 Heating advice
NB: Logs that have been stored outdoors or in a cold room
should be brought indoors 24 hours before use to bring them
up to room temperature.
There are various ways of heating the stove but it is always
important to be careful about what you put in the stove. See
the section on "Wood quality".
NB! Combustion with too low air supply can lead to poor
combustion, poorer efficiency, high particulate emissions, black
carbon and other health and climate hazardous compounds.
Wood quality
By quality wood we mean most well-known types of wood
such as birch, spruce and pine.
The logs should be dried so that the moisture content is no
more than 20%.
To achieve this, the logs should be cut during the late winter.
They should be split and stacked in a way that ensures good
ventilation. The wood stacks should be covered to protect the
logs from rain. The logs should be brought indoors during early
autumn and stacked/stored for use in the coming winter.
Be especially careful never to use the following
materials as fuel in your fireplace:
•
Household rubbish, plastic bags, etc.
•
Painted or impregnated timber (which is extremely toxic).
•
Laminated wooden planks.
•
Driftwood
These may harm the product and are also pollutants.
NB: Never use petrol, paraffin, methylated spirit or similar
liquids to light the fire. You may cause serious injury to
yourself and damage to the product.
5.6 Wood consumption
Jøtul F 500 ECO has a nominal heat output of ca. 8,8 kW. Use
of wood, with nominal heat emission: Approx. 1,97 kg/h. The
size of the logs should be:
Kindling:
Length: 30-55 cm
Diameter: 5 cm
Amount per fire: 5-8 pieces
Firewood (split logs):
Length: Ca 35 cm
Diameter: Approx. 8-13 cm
Intervals for adding wood: Approximately every 80 minutes
Size of the fire: 1,97 kg (nominal efficiency)
Amount per load: 3 pieces
The given testresults have been obtained by loading 3 logs á
35 cm, total weight of 1,97 kg.The logs are laid across. Valve
set for about 40 % air.
The maximum amount of fuel specified in this manual
should not be exceeded, overloading can cause excess
smoke.
5.7 Danger of overheating
The fireplace must never be used in a manner that causes
overheating.
Overheating occurs when there is too much fuel and/or too
much air so that too much heat develops. A sure sign of
overheating is when parts of the fireplace glow red. If this
happens, reduce the air vent opening immediately.
Seek professional advice if you suspect that the chimney is
not drawing properly (too much/too little draught). For further
information, see «4.0 Installation» (Chimney and flue pipe).
