Mid-season use
The FIRETRONIX firebox uses the
chimney/flue draw to draw in combustion air
and discharge smoke.
As the external temperature increases, draw
decreases continuously. Check the chimney
draw before lighting the fire
when the external temperature exceeds
10°C.
If the draw is weak, start by lighting a “star-
ter” fire using small pieces of firelighter.
Fuel can be introduced once correct draw
has been established.
Air flow in the room where the
firebox is installed
The FIRETRONIX firebox can only work pro-
perly when the room in which it is installed
has a sufficient flow of air for combustion.
Ensure that there is a sufficient flow of air
before lighting the fire.
Combustion air supply devices must not be
tampered with.
However, should the air volume seem scarce
and the type of building where the fireplace
is installed be particularly air-tight, an extra
air intake of 120 cm² must be installed as
mentioned previously.
Lighting the fire when the firebox is cold
1
. Check that the bed of ash is not too high.
Maximum height: 5 cm below the edge of the
door.
If the bed of ash is too high there is a risk of
embers falling out of the firebox when the
door is opened to add more wood.
2
. Do not cram too much wood into the fire-
box. Place a piece of firelighter amid the pie-
ces of wood and light it.
Firelighters are practical aids for starting the
fire.
Warning: large pieces of wood do not light
well in a cold firebox and give off noxious
gas.
Never use petrol, alcohol or similar substan-
ces to light the fire!
Fuel and calorific power
From a technical point of view, combustion has
been optimised in terms of both emissions and
the design of the firebox and the relative air supply.
Please support our commitment to a clean envi-
ronment by complying with the following instruc-
tions regarding the use of fuels that do not con-
tain or produce noxious substances.
Only use natural or seasoned wood, or wood
briquettes, as fuel. Damp, freshly cut or poorly
stored wood has a high water content and the-
refore burns badly, producing too much smoke
and not enough heat.
Only use fire wood that has been seasoned for
at least 2 years in a dry, well-ventilated environ-
ment.
That way the water content will be less than 20%
of its weight. Savings can thus be made on fuel
as seasoned wood has greater calorific power.
Never use liquid fuels such as petrol, alcohol or
similar substances. Do not burn waste.
Radiation range
Do not position any combustible objects
within the radiation range of the glass door.
Commissioning
The paint on the firebox must be cured until
the working temperature is reached for the
first time.
This can cause an unpleasant smell.
In this case, thoroughly ventilate the room
where the fireplace is installed. The smell will
disappear once it has been used for
a few times.
Burning hazard
The external surfaces of the FIRETRONIX fire-
box, above all the ceramic glass door, beco-
me hot. Do not touch – burning hazard!
Ensure children are warned of this hazard.
Keep children away from the firebox when lit.
Air grilles
Do not close or obstruct the hot air outlets.
This can cause overheating inside the cove-
ring.
Using the firebox with the door open
The firebox must be kept under constant con-
trol when used with the door open. Burning
embers can shoot out of the firebox.
Adding fuel
A protective glove should be used when adding
wood to the fire, as the handle can become hot
when the fireplace is used for an extended
period of time.
Open the door slowly. This will prevent vortices
from forming causing smoke to escape.
When is the right time to add wood?
When the fuel has been consumed almost to the
point that it becomes embers, or when “Load
Wood” is displayed on the panel.
3
. At this point close the door of the firebox and
press the ON/OFF button, watching over it for a
few minutes. If the fire
goes out, open the door slowly, place another
piece of firelighter amid the wood and light it.
4
. Wood can be loaded into the firebox at any
time as long as the embers have not died away
completely. However, Firetronix can alert you
when the moment is right for adding more
wood.
Loading fuel when the firebox is hot
Using the glove supplied with the fireplace,
raise the door and add the desired amount of
wood, placing it on the existing embers.
This will allow the wood to heat up, expelling
the humidity contained within in the form of
steam. This leads to a reduction in tempera-
ture inside the firebox. Volatile substances
released from the combustible material at
this point call for a good supply of air to
ensure that this stage, which from a technical
point of view of the emissions is quite critical,
proceeds quickly, reaching the temperature
needed for correct combustion.
Further suggestions:
Always use the smallest pieces of wood to
light the fire.
They burn more quickly thus bringing the fire-
box up to the right temperature more quickly.
Use larger pieces of wood to build the fire
up.
Some types of wooden briquettes swell in the
firebox, dilating due to the heat and increa-
sing in volume.
Always place the wood deep into the firebox,
almost touching the back wall, so that if it
slips it doesn’t fall onto the door.
Removing the ash
Ash can be removed using a shovel or an ash
vacuum. Ash must only be kept in non-com-
bustible containers as residues of embers can
reignite even more than 24 hours after the
last combustion.

WARNING:
Loading an excessive amount of wood onto the fire or using unsuitable fuel can cause
overheating.
N.B.
Seasoned wood has a calorific power of about 4 kWh/kg, whilst the calorific power of fresh wood is
only 2 kWh/kg. So twice the amount of fuel is needed to obtain the same calorific power.
