KEDDY K800 Series Installation Instructions Manual - page 13
As the output modes are controlled automatically, the
burning time for the wood loads mentioned above will
be different.
3 - 4 kW approx. 60 - 80 minutes
6 - 7 kW approx. 50 - 60 minutes
8 - 9 kW approx. 40
For the automatic mode to work, the stove must have
a power supply. If for some reason there is no access
to electricity, the stove can be used as a traditional
stove. If you follow these instructions carefully, you
will still achieve very good efficiency and environmen-
tal results.
FIRING IN MANUAL MODE
If for some reason there is no power supply, the
stove's damper control will function as a step-less
damper. (See the illustration below).
When you optimise firing manually, you should meas-
ure the amount of burned wood per hour. The K800 is
not intended for an output exceeding 9 kWh, i.e. never
exceed the maximum amount of recommended wood
per hour. This not only impairs the efficiency there is
also a risk of overheating the stove and chimney. Suit-
able size and quantity of firewood for the K800 when
firing with manual damper:
Kindling:
Length approx. 25 - 30 cm
Diameter approx. 2 - 5 cm
Quantity approx. 1.9 kg
Split logs:
Length approx. 25 - 30 cm
Diameter approx. 6 - 10 cm
Quantity 1.7 - 1.9 kg / load
Max. amount 2.8 kg / hour
In manual mode, the damper is closed completely
when it is turned to the left and is open to the maxi-
mum when it is turned to the right (see the illustration
below).
The amount of air needed for burning, e.g. 1.9 kg of
wood in one hour depends on several parameters.
The length of and draught in your chimney, how hot
the stove and chimney are, i.e. how long you have
fired. The basic principle, however, is that the stove
has to burn calmly and harmonically and, for a hot
stove, the damper control usually does not exceed
30% in order to achieve this with an output of 6 - 7
kW. (The damper control stands at 50% in the illustra-
tion above.)
FIRING AND FILLING WITH WOOD
Note that when the stove is new, a certain smell can
arise. This is caused by the paint and anti-corrosion
agent hardening. Ensure good airing and the smell will
disappear after the stove has been fired a couple of
times.
Open a window near the stove, if there is negative
pressure in the house. Leave the window open until
the fire starts to burn normally. Light the fire in the fol-
lowing way:
Automatic mode
1. Open the door. Put in some crumpled newspaper or
firelighters.
2. Put in 1.9 kg of kindling. Pile up the wood crosswise.
3. Light the fire.
4. Close the door and wait until the fire has burned
down before you fill up the stove again. (If the chim-
ney is cold or if there are unfavourable weather
conditions, you may need to keep the door ajar
during the first five minutes in order to establish
a satisfactory chimney draught.)
When the stove
is cold during the first fire, it will burn the wood faster
than specified in the table but the stove will find its
rhythm from the second fire, when its has reached its
operating temperature.
5. If necessary, change the output mode. (You have to
wait for 15 minutes after you have lit the stove before
you can do this.)
Manual Mode
1. Open the door. Put in some crumpled newspaper or
firelighters.
2. Put in 1.9 kg of kindling. Pile up the wood crosswise.
3. Turn the damper all the way to the right (max) and
light the fire.
(If the chimney is cold or if there are unfavourable
weather conditions, you may need to keep the
door ajar during the first five minutes in order to
establish a satisfactory chimney draught.)
4. Let the first fire burn down with full damper. This
is in order to allow the stove to reach its operating
temperature quickly. Light a new fire of the desired
size. Wait a couple of minutes until the fire has started
burning properly. Then turn the damper to the left, until
you have achieved a calm and harmonic fire.
Note! The reason why we want to achieve the op-
timum operating temperature in the stove quickly,
both in automatic and manual mode is that the
stove works most efficiently at this temperature.
This minimises the emissions and maximises the
heat generation.
