5. FUEL
100% pressed pine wood pellets certified
according to the EN PLUS A1 standard are the
only fuel allowed for use in this boiler.
The pellets used must be certified and in
accordance with EN Plus 14961 or 17225-2.

5
Fuel characteristics
Pellets are produced by pressing wood chips and
sawdust. They are obtained without the addition
of any foreign substance, such as adhesives,
lacquers or synthetic substances.
Pressing through a matrix of holes and the heat
produced by friction and pressure, activates
natural wood binders that in this way ensure the
shape of the pellets even without the addition of
binders.
The production and consumption of pellets is
based on the rational use of renewable energy
with zero impact on the CO 2 cycle, which respects
environmental protection standards.
This is the only fuel indicated for this equipment.
Yield and power vary depending on the quality of
pellets used.
For correct operation you must use pellets
according to the characteristics below.

The stove is equipped with a hopper (deposit) for
pellets with a capacity for 1 bag of 15 kg.
The pellet supply must only be carried out
through the feed door that gives access to the
load compartment.
Figure 1- Power Port
Pellet storage
The operation of the stove largely depends on the
quality and conservation conditions of the pellets,
for this reason they must be stored in a dry place
where they do not reach too low temperatures.
Poor packaging of the pellets can lead to the
breakdown of particles and create sawdust.
Sawdust is responsible for the malfunction of the
power system and can block it.
We advise you to store a few bags of pellets
in a warm and dry place, because cold (5ºC)
and/or wet pellets reduce the calorific value of the
fuel and cause more dirt, requiring more rigorous
maintenance and cleaning.
6. UNLOADING AND TRANSPORT
The stove must be transported vertically without
rocking during the entire transport process.
The stove's brazier as well as other components
can come loose causing damage to the product.

6
The stove's packaging must not be impacted or
hit by other objects or equipment, under penalty
of causing damage that will compromise the
stove's future operation.
Make sure that the means of transport used has
a capacity greater than the weight of the stove.
7. INSTALLATION GUIDE
To obtain the best performance from the stove
and uniform heating of the room, you must
comply with some essential rules.
Improper installation will compromise the safety
and proper functioning of the stove.
When installing the equipment, all national and
local regulations, as well as European standards,
must be observed.
Leveling the stove
The stove must be leveled using a bubble water
level at the back, front and at an angle from apex
to apex.
Installation constraints
It must be safeguarded that no mechanical
exhaust fans or collective ventilation ducts are
installed at the installation site.
In any case, it must be safeguarded that the
installation site is not in a depression, preventing
the simultaneous operation of the systems
mentioned above, since this will compromise the
normal functioning of the stove and possible
release of dangerous fumes. Check point 15-
Models and technical characteristicsfor more
information.
Retriever installation location
When installing the stove, the minimum distances
from combustible surfaces must be ensured. In
the case of non-flammable walls/objects these
distances can be reduced by half.
The floor protection to support the stove must
guarantee fire resistance in accordance with
European standards. Never place the stove
directly on wood, carpet or other combustible
materials.
During installation, structures, coverings, beams,
etc., must be protected from combustible or
flammable material and which are exposed to
excessive heat, either from the stove or the
chimney, particularly when crossing partitions
and false ceilings. In these cases, appropriate
thermal insulation should be used, namely
vermiculite.
Check point 15 - Models and technical
characteristicsfor more information.
The manufacturer will not be responsible for
changes in the properties of the materials
surrounding the fireplace and chimney.
Air intake
The heat generated by the stove results from the
heat produced by the chemical reaction of
combustion of the pellets in the combustion
chamber.
For this combustion to occur under the best
conditions, it is necessary to safeguard the
correct amount of oxidizing agent (oxygen
present in the air).
During operation, the stove absorbs a quantity of
air from the room where it is located, which
enters the combustion chamber through an air
inlet located at the back of the stove, which can
be channeled to the outside.
You must not use bends or tubes with a section
smaller than 60mm, nor a maximum length
greater than 800mm.
You must also safeguard that this admission will
never be obstructed from the outside and that it
is at least 20 cm from the ground.
Outside, you should put protection against rain
and wind.
Safeguard the requirements and relative to
ventilation and air supply referred to in point 7.2-
Installation constraints.
In the figure below you will find several examples
that will help you to verify the stability and
correction of the flame.

7
Correct combustion
Bright flame with light
yellow color and minimum
amount of pellets in the
brazier
Incorrect combustion
Flame too bright too
much oxidizer.
Too many glowing pellets
come out of the brazier.
Correct the amount of air
(from 0 to +5) correct the
auger if necessary (from
0 to -5).
If not, contact technical
support.
Incorrect combustion
Flame too dark yellow,
wobbling, with too many
unburned pellets in the
brazier.
Check that the door or
ash bin is closed.
Otherwise, correct the
amount of air (from 0 to
+5) correct the auger if
necessary (from 0 to -5).
If not, contact technical
support.
Smoke evacuation duct
The smoke discharge from the stove is with
positive pressure in relation to the surrounding
environment, so it is essential to guarantee the
tightness of the various chimney joints. The
smoke evacuation duct must be independent
from other equipment.
To guarantee the correct extraction of the smoke,
it is mandatory that the first section of the
chimney be vertical with a height of not less than
1.5 meters.
The horizontal sections must not be longer than
1.5 meters with a slope of at least 5%.
The chimney outlet must comply with EN 1856-2
for built-in masonry chimneys and EN 1856-1 for
insulated outdoor chimneys. It must be in 0.5mm
thick 316 stainless steel with dimensions
respecting what is indicated in the equipment
characteristics, regarding the smoke outlet.
The smoke duct must have a diameter of 120
mm, with male/female joints fitted with a high-
temperature silicone gasket (>200ºC) with an
inverted installation (male downwards) to
prevent condensation from flowing out of the
chimney.
For chimneys over 5 meters high, their section
must change to a diameter of not less than
140mm after 5 meters. The dimensioning of the
smoke duct must be done considering 0 Pa.
The piping used outdoors must be in double-
walled stainless steel, in order to avoid
condensation and corrosion of the same, resulting
from the thermal shock.
It is forbidden to install dampers, butterflies or
valves that strangle the chimney's draft capacity.
The fume exhaust capacity depends on several
factors, including the height of the chimney.
Depending on these factors, it may be necessary
to make adjustments to the stove's operating
parameters. Excess draft when it is not possible
to correct it by changing parameters such as air
intake and pellet loading, it will imply the
installation of an air intake valve to the chimney.
If necessary, contact the technical assistance
service.
7.5.1. Basic requirements
The chimney must be made of stainless steel duct
and must rise 50 cm above the highest point of
the building's roof.

8
Assembly Scheme
The Aquatek stove is a pellet stove for central heating, so it can never be used without water circulation,
under penalty of structural damage.
7.6.1. Basic installation
The stove must be installed on the mounting structure as shown in the images below.
Figure 2- Settlement structure
Start by separating the stove from the base.

Figure 4- To open, place the key, activate the opening system and pull the stove
Install and screw the laying structure, install the 80mm diameter pipe that comes with the equipment
and adapt it to a diameter equal to or greater than 120mm and connect the 50mm diameter air intake
to the outside if you want a watertight installation or if there are extractors/ extractor hoods in the room
where your stove will be installed.
Note that, for chimneys with a height greater than 5 meters, the outlet diameter must be at least 140mm,
at least, as referred to in point 7.5- Smoke evacuation duct
Figure 5- Fixing the base to the laying structure
Adjust the rim to the base of the equipment. Screws for tightening the frame to the base and to the
plasterboard are provided, the latter being optional.

14
Hydraulic installation
The boilers and stoves for central heating are
equipped with a complete hydraulic kit, with a 2
bar safety valve, circulating pump, non-return
valve and a 6 liter expansion vessel.
The connection to the hydraulic network must be
carried out as shown in the image below.
Figure 14- Hydraulic Connections
The safety valve must be connected to the sewer,
taking into account that it must be properly
siphoned.
Figure 15- Hydraulic connection diagram
The equipment leakage is carried out by the
safety valve installed in the boiler body.
Working pressure between 1 and 1.5
bar
NOTE: The volume of water in the installation in
addition to the boiler water can be managed with
the integrated 6 liter expansion vessel.
However, the installer must safeguard for each
installation, the need to install an additional
expansion vessel, taking into account the total
volume of the installation.
Figure 16- Installation scheme without DHW
For a more detailed consultation of the hydraulic
and smoke connections, see point 14of this
manual.
Figure 17- Installation diagram with accumulation
The equipment does not have control for the
production of hot water by accumulation. Neither
will it start combustion or start the pump if the
tank temperature drops below the desired value.

15
In an installation with a DHW accumulator tank,
the control of the 3-way valve must be done by
the thermostat of the DHW tank, this is not a
function of the equipment, but an option not
supplied, which the installer can add to the
installation.
7.7.1. Installation configuration
technical parameters:
Default installation diagram
By default, the equipment is NOT prepared to
work with the production of domestic hot water
by accumulation.
If there is an installation for the production of
DHW by accumulation, the installer will not
change the type of installation because the
equipment does not have control for the
production of hot water by accumulation. Neither
will it start combustion or start the pump if the
tank temperature drops below the desired value.
In an installation with a DHW storage tank, the 3-
way valve must be controlled by the DHW tank
thermostat. In this case, the installer must place
the DHW temperature thermostat at the middle
of the tank height between the inlet and outlet of
the internal coil. As close as possible to the
thermometer on the cylinder itself so that the
readings are equivalent.
Installation diagram with AQS
Electrical installation
Installation must be carried out
by qualified personnel
according to EN 10683. Ensure
that the electrical installation is
earthed.
With the switch off,
connect the cable to the wall
socket and plug.
Turn on the switch to electrically
supply the stove.
For more information, see point
13- Electrical schematicsof this manual.
Installation test
8.2 - Lightingand 8.3- Stopmust be taken into
account REF _Ref399004928 \w \h.
Maintenance
When installing the equipment, the space
required for maintenance and cleaning of the
equipment and respective connection and smoke
evacuation ducts, as well as the respective
hydraulic networks (water models) must be taken
into account.
For more detailed information, see point 11-
Maintenance.
Other information
7.11.1. Calculation of thermal
power and average
consumption/hour
The calculation of the thermal power required for
heating a given space can be performed using a
very simple method, since, on average, the
heating power required for a properly insulated
room is approximately 40 W/m 3.
If we want to heat a space with 100m 3 then we
have:
100m 3 x40W/m 3 = 4000W, that is, 4 kW.
For this main heating requirement, a 6.5 kW
appliance will therefore suffice.

The transmission and reception distance may be reduced in the case of electromagnetically noisy
environments: other devices such as wireless headphones, sender, toys or other devices may influence
system performance. Check for the presence of such instruments and be sure to turn them off in order
to avoid electromagnetic wave pollution. If more remote thermostats are nearby, it is necessary to
associate the remote control with each specific boiler (see settings menu).

Standby
By pressing the button for 3 seconds, when the main screen is
displayed, it is possible to completely turn off the remote control
and thus reduce battery consumption. This feature is to be used in
case of prolonged non-use of the remote control. If this function is
activated, the boiler will no longer use the ambient temperature as
a reference. To turn on the remote control, press the button
twice.
