First burning cycle
First check that the combustion tunnel is firmly seated and that the
air control pipe, 34a, has not moved during transport.
The first fire to be lit should be started carefully so that any remain-
ing moisture in the ceramic can vaporise slowly. Lighting a fierce fire
may crack the ceramic Only light a small fire the first time. Once the
ceramic parts are dry, you can light a full-size fire. The ceramic does
not take on moisture when the boiler is being used.
Lighting a fire without gas
• Move the main switch to the green position. Set the thermostat to
120°C.
• Arrange kindling on top of crumpled newspaper. Push some of the
paper down into the hole in the ceramic. Close the firewood hatch.
• Press “FAN START”, the fan starts. Open the bypass damper. Open
the ash hatch and light the paper.
• The wood must be properly ignited (flue gas temperature approx.
120°C). Leave it to burn until there is a layer of vigorous embers.
Open the ash hatch and the bypass damper.
Lighting a fire with the gas lighter
• Move the main switch to the green position. Set the thermostat to
120°C.
• Arrange medium size blocks of wood over a layer of kindling, then
fill the rest of the combustion chamber with firewood.
• Press “FAN START”, the fan starts.
• Open the bypass damper and ash hatch. You can leave the fire-
wood hatch open until you can see the flames.
• Ignite the gas lighter and insert it into the nozzle in the opening
(see the diagram below). After around 1-2 minutes the firewood
should be lit.
• Remove the gas lighter, close the ash hatch, close the firewood
hatch, close the bypass damper. Check that you can see flames in
the inspection glass.
Adding wood
To prevent smoke and flames entering the
room when adding wood, you must open
the bypass damper before opening the
firewood hatch.
Only add more firewood when all that is left
of the previous load is a layer of embers.
Constantly “topping up” with the occasional
log reduces efficiency significantly.
Even out the layer of embers. Add more
firewood. The amount of firewood depends
on the temperature in the accumulator – do
not allow the temperature to get too high.
Filling the boiler with firewood increases the temperature of the
boiler and a 1500 litres gal. accumulator by 40- 50°C. Stack the
wood carefully, the boiler can be completely filled.
Close the firewood hatch and then the bypass damper. If the flue gas
temperature increases, you know that the firewood has ignited.
When the firewood has burnt and the flue gas temperature has fallen
to below 120°C, the fan and charging pump to the accumulator stop
running.
Bypass damper
The boiler’s bypass damper must only be used for adding wood dur-
ing a burning cycle, in order to prevent smoke entering the room.
When the bypass damper is open, the boiler works like an updraught
burner with shorter flue gas paths. This increases the flue gas tem-
perature and reduces efficiency.
Do not forget to close the damper after adding firewood.
Controlling combustion
Air is supplied to the boiler partly through the primary damper, which
is hidden behind the cover plate on the front, and partly through the
secondary damper in the lower ash hatch. Combustion is control-
led by the draught created by the fan, and by the addition of oxygen
through these dampers. To optimise combustion and efficiency, the
flue gas temperature should be 175- 210°C.
The secondary damper can be
adjusted so that the flame is light
yellow.
The soot indicates the quality of
combustion. If it is very dark or
black, the combustion process is not
receiving enough air. In this case,
the damper should be opened more.
Efficient combustion gives the soot a
grey-brown colour.
RISK OF BURNS
Do not open the boiler hatches if the fan is not run-
ning and a fire is burning in the boiler. If you are not
sure whether a fire is burning in the boiler, first open
the bypass damper then open the firewood hatch a
couple of centimetres very carefully.
There is a risk of flames exiting through the hatch,
so take the greatest possible care!
