Startup
1. the bypass damper must be in the closed position.
2. place kindling in the boiler, with paper if you are using it.
3. the main switch must be set to on (the green area must be visible).
4. thermostat, FAN STOP, set to 120°C (250°F).
5. press “FAN START”, the fan starts.
6. light the boiler – gas is recommended.
First.burning.cycle
The first fire to be lit should be started carefully so that any remaining
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 ceram-
ic parts are dry, you can light a full-size fire. The ceramic does not take
on moisture when the boiler is being used.
Lighting.-.start
•
Place kindling in the boiler, followed by crumpled newspaper.
•
Press “FAN START”, the fan starts. Light the paper. Leave the firewood
hatch slightly open.
•
Wait a while before closing the firewood hatch. The wood must have
properly ignited (flue gas temperature approx. 250°F). Leave it to burn
until there is a layer of vigorous embers.
Lighting.a.fire.with.the.gas.lighter
•
Arrange medium size blocks of wood over a layer of kindling, then fill
the rest of the combustion chamber with large blocks.
•
Close the firewood hatch.
•
Ignite the gas lighter and insert it into the nozzle in the hole at the
top of the inner ash hatch. Move the flame from side to side, and the
wood should have ignited after about a minute.
Adding.wood
When the time comes to add more wood, open the bypass damper be-
fore the firewood hatch. This prevents smoke entering the room and
the risk of flames exiting the boiler when you add firewood.
Even out the layer of embers. Add more fire-
wood. The amount of firewood added de-
pends 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 400 gal. ac-
cumulator by about 110- 120°F. Stack the
wood carefully.
Close the firewood hatch followed by the by-
pass 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 250°F,
the fan and charging pump to the accumula-
tor 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
All air passes into the boiler through the
draught hatch in the ash hatch. Combus-
tion is controlled by the draught created
by the fan, and by the addition of oxy-
gen in primary, secondary and tertiary air
through the inner ash hatch.
To optimise combustion and efficiency,
the flue gas temperature should be 350-
400°F.
45. Hole for gas lighter.
46. Secondary damper, normally closed.
47. Tertiary damper.
The tertiary air, 4�, 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. If you are burning wood with a moisture content of
18%, the opening should be about 4 mm.

the steps in reverse to remove it.

RISK OF BURNS
Do not open the boiler hatches if the fan is not running
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!
