The complete set of parts provided with the unit guarantees its operation and energy
efficiency; these parts should only be replaced with original parts provided by an
authorised technical assistance centre.
The unit must be subject to maintenance at least once a year by the installation
engineer.
This manual is provided with the product. Please keep it close to the unit.
2.1. For your safety, please remember:
The pellet boiler is a biomass heating unit. Be sure to carefully read and
understand the information contained in this book, before handling or operating the
unit;
Make sure the hydraulic circuit is correctly assembled and connected to the water
supply system before turning on the pellet boiler;
The boiler is not intended for use by children or persons with a physical, sensory
or mental handicap, unexperienced or unaware of its proper use, unsupervised or not
instructed concerning the use of the unit;
Do not touch the boiler when barefoot or any part of your body is wet or humid;
5
Do not tamper with any safety or adjustment features of the unit without the
manufacturer's authorisation;
Do not cover or reduce the size of the aeration vents existing near the installation
area;
The pellet boiler needs air circulation for proper combustion, so possible air
tightness of the location or any existing air extraction sources in the room may
prevent the unit’s proper operation;
The existence of aeration vents is a requisite for proper combustion;
Do not leave the packing materials near children;
During the unit's normal operation do not attempt to open the boiler's door;
Avoid direct contact with parts of the unit that overheat during operation;
Check the fume duct for blockages before turning on the unit after a long period
of inactivity;
This pellet boiler is intended for residential use in a protected environment. The
unit might get turned off by any safety systems installed in the household. If this
occurs, contact the technical assistance. Under no circumstances should you disarm
the safety systems;
The pellet boiler is a biomass heating unit equipped with a fume exhaustion
system powered by an electric exhauster. The occurrence of any power failure during
its use may prevent the fume exhaustion thus causing the room to be filled with
smoke. For this reason, you should have a natural fume exhaustion system, like a
chimney, installed;
Solzaima offers you an optional safety system which allows the boiler unit to be
connected to a UPS to allow that during any power failure the fume exhaustion
system will still operate until complete exhaustion of all boiler fumes;
If you intend to use the boiler unit unsupervised or while you are away from
home, you should use the above safety system for total safety during any power
failure;
During operation, NEVER turn off the pellet boiler by unplugging the power cord
from the wall socket. The fume exhaustion system on the pellet boiler is power-
operated so disconnecting the power plug will prevent the exhaustion of combustion
fumes;
6
Before performing any maintenance or assistance to your unit, disconnect it from
the power mains. Before performing any of these operations, allow the unit to cool
down completely (if previously operating);
Never touch the interior of the boiler when connected to the power mains;
For this boiler, the maximum setting for the water temperature that can be
specified by the user (water set-point temperature) is 85°C. If a temperature of 90ºC
is reached, the boiler automatically turns off causing the corresponding alarm to go
off.

4. Installing the pellet boiler
Before installing the unit, please perform the following steps:
When receiving the package, inspect the product to check for completeness
and any signs of damage. Any damages or defects should be acknowledged before
the unit is installed;
The boiler has four adjustable feet at the base which allow for an easy setting of
the height when the unit is installed on a non flat surface;
Figure 4 – Adjustable feet
Remove the instruction manual from the package and hand it over to the client;
Connect the combustion gas outlet to the fume exhaustion duct going out of the
building (through a chimney, for instance) using a 100mm-wide piping – check the
diagrams under section 4;
If using a tube for admission of external air for combustion, this tube must have
a maximum horizontal length of 60cm, straight and with no elbows;
Perform the hydraulic system installation (please refer to section 4.5);
Connect the 230 VAC power cable to a grounded wall power socket;
The remote control of the unit includes a programmable thermostat. As an
option, a conventional external programmer may be used (not provided with the
unit) to automatically setup the unit's operating periods.
4.1. Installation requirements
Figure 5 specifies the minimum separation distance between the pellet boiler and
particularly flammable surfaces.
10
The top of the boiler must be separated at least 100cm from the ceiling, especially in
rooms with ceilings consisting of flammable materials.
The base supporting the boiler cannot be made of combustible material, so make
sure you always put in place an adequate protection.
a) b)
Figure 5 – Minimum separation distances from all surfaces: a) top view of an installed
unit; b) side view of an installed unit
WARNING!
Keep combustible and flammable materials away from the unit, at a safe distance.
4.2. Installation of ducts and fume exhaust systems:
The gas exhaust pipe must have been designed for this purpose, in compliance
with local requirements and in accordance with any existing applicable regulations.
Important! An inspection T-tube with airtight lid must be attached to the
outlet of the unit’s exhaust pipe to allow for the regular inspection of the system or
release of heavy dust and condensates.
As shown in Figure 5, the assembly of the exhaust pipe must include inspection
couplers to allow access for cleaning and maintenance operations.
Under normal operating conditions, the combustion gas exhaustion should create
a draught of 12 Pa one meter above the chimney neck.
The boiler should make exclusive use of the chimney.
All pipes on the exterior to the installation location must have an internal diameter
of 100mm and double stainless steel insulation.
11
The fume exhaust pipe may generate condensation, so we recommend that
the appropriate systems for collecting condensates should be installed.
4.3. Installation in the absence of a chimney
The installation of the pellet boiler in the absence of a chimney should be performed
as shown in Figure 6, by directing the fume exhaust pipe (with a minimum inner
diameter of 80mm for the air model and 100mm for the water model) straight
outwards and onto the top of the roof.
Double-wall stainless steel insulated pipes must be used and these pipes must be
properly fastened to avoid condensation.
The installation of an inspection T-tube at the base of the piping must be considered
to allow for the performance of periodic inspections and annual maintenance, as
shown in Figure 6. Figure 7 shows the basic requirements for installing the boiler’s
flue pipe.
Figure 6 – Side view: installation with a chimney with inspection coupler.
12
a)
b)
13
c)
Figure 7 – Examples of standard installations.
Failure to comply with these requirements may prevent the correct operation of
the boiler. Follow all the instructions shown on the diagrams.
Because the boilers operate with the combustion chamber in draught it is an
absolute requirement to install a fume exhaust pipe to allow for the proper extraction
of the combustion gases.
Fume duct materials: The tubing must be made of 0.5mm thick rigid stainless steel,
use with pipe fittings to attach different sections and accessories.
Insulation: The fume ducts must be double-wall and properly insulated to make sure
that fumes do not cool down going outwards, which would cause inadequate
circulation and condensation that may damage the unit.
Out T-tube: Make sure you attach to the boiler output a fitting T-tube.
14
Anti-downdraught terminal: An anti-downdraught terminal must be installed to
avoid the backflow of fumes.
Draught in the chimney: The following figures show three standard diagrams
containing the correct length and diameter specifications. Any other type of
installation that you choose to perform must guarantee a draught of 12 Pa
(0.12mbar) measured at maximum heat and power.
Ventilation: For the boiler’s correct operation it is necessary to have an air inlet
with a minimum section of 100cm2 available at the installation location,
preferably near the rear panel of the unit. The boiler is equipped with a round pipe
( 50mm) that may be connected to the exterior of the house.
4.4. Installation with a chimney
As shown in Figure 8, the 100mm exhaust pipe of the pellet boiler is installed
directly on to the chimney. If the chimney is too large, we recommend that you attach
an 80mm pipe to the fume outlet.
You should also consider attaching a T-tube to the base of the pipe to allow for
periodic inspection and annual maintenance, as illustrated in Figure 8.
Figure 8 – Side view: installation with chimney with inspection coupler.
We do not recommend that you use the boiler in rough weather conditions that may
seriously impact the draught (particularly with very strong winds).
15
If you do not use the unit for a long time, check it to make sure that the flue pipes are
clear before lighting the fire.
4.5. Hydraulic installation
* Chapter 12 (installation diagrams) contains the optional connection diagrams for
central heating installations, with or without water heating for household use;
* The pellet boiler is equipped with a circulation pump, an expansion vessel (6 litre
volume in the 18kW compact boiler model) or 10 litre volume (in the 24kW compact
boiler model) and a 3 bar safety valve;
* Operating pressure ranges from 1-1.5 bars;
* To empty the unit, attach a T-tube with a tap at the outlet (connected to the
household sewage); the safety valve (3 bar) outlet should also be connected to
the household sewage;
*The heating fluid must consist of water with an anti-rust, non-toxic product added in
the quantity recommended by the manufacturer. If the location where the boiler or the
fluid pipes are installed is likely to freeze, the installation engineer must add to the
circulating fluid the amount of antifreeze product recommended by the manufacturer,
to avoid it to freeze at the estimated minimum temperature.
5. Fuel
The pellet boiler must be operated exclusively with pellets. No other fuel may be
used.
Use only pellets certified by standard EN 14961-2 grade A1, with a 6mm diameter
and a length between 10-30mm.
16
The pellets may have a maximum humidity of 8% their weight. To guarantee a good
combustion, the pellets must maintain these characteristics so they should be stored
in a dry place.
The use of pellets other than those recommended may reduce the efficiency of the
unit and cause deficient combustion.
You should always use certified pellets and must not forget to test a sample
before buying large bulks.
The physical/chemical properties of the pellets (i.e. the calibre, friction, density and
chemical composition) may vary within specific tolerances and according to each
manufacturer. Please note that this may cause alterations to the combustion feed
that would consequently cause the need to use different quantities of pellets.
The boiler allows the quantity of pellets to be adjusted during start-up and at
the different power ranges by ± 25% (refer to section 7.3.6 of the manual – power
and transition settings).
WARNING!
The unit CANNOT be used as an incinerator.
6. Using the pellet boiler
Recommendations
Before starting up the unit, please check the following:
Make sure that the unit is properly connected to the power mains using the
230VAC power cable.
17
Figure 9 – Electric power plug.
Check to see whether the pellet reservoir is supplied with pellets. Inside the pellet
reservoir is a safety grid to prevent users from reaching the worm screw.
Before each time you light up the boiler, make sure the burner is unobstructed.
The boiler's combustion chamber and door are made of iron painted with high
temperature-resistant paint; this will cause the releasing of fumes during the first
burning sessions due to paint curing.
Make sure the hydraulic circuit has been correctly assembled and that it is connected
to the water supply.
You should check that there is sufficient ventilation in the room where the unit is
installed; otherwise it will not work properly. You should therefore check to see
whether there are other heating air-consuming units in the room (e.g. gas units,
diesel boilers, etc.); these should not be used simultaneously with the unit.
The pellet boilers have a probe for measuring the room temperature. This probe is
attached to the grid on the rear panel (Figure 10). For a good reading of the room
temperature, avoid the contact between the end of the probe and the chassis of the
boiler. You may also attach the probe to the wall beside the unit.

8. Starting-up the unit
To start operating the pellet boiler, press the start/stop button for 3sec. The display
should indicate "Acendimento" (Lighting) until completion of this phase.
The pellets are fed through the supply channel and into the burning basket
(combustion chamber), where they will be ignited using a heat resistor. This process
may take between 5-10 minutes, depending on whether the worm screw used to
push through the pellets has been previously filled with fuel or is empty. Upon
completion of the ignition phase, the word "On" should appear on the display. The
heating power can be adjusted at any time by pressing the power selection button for
approximately 1 sec. Users can choose between five preset power levels.
The selected power level is shown on the display. The initial power level at each
start-up will be the power level set before the last stop.
8.1. Stopping the unit
The stop sequence of the unit is started by pressing the start/stop key for 3sec.
The display shows the message “desactivação" (Stopping) until the completion of
this phase. The exhaust system remains active until the fume temperature reaches
104ºF (40ºC), to ensure the full burn of all the material.
8.2. Turning off the unit
The unit should only be disconnected after full stop of the operation. Make sure the
display shows the 'Off' sign. Make sure that the display indicates “Off”. If necessary,
disconnect the power cable from the mains.

10. Maintenance
The Solzaima pellet boiler requires careful maintenance. The major concern is to
clean the ashes from the pellet burning area at regular intervals. This procedure can
42
be easily done using a common household vacuum cleaner. The cleaning operation
should performed after each burn of approximately 66lbs (60kg) of pellets.
Note: However, before cleaning, the boiler must be turned off and the unit should be
allowed to cool down to prevent personal damage.
Cleaning the Boiler
The boiler’s maintenance operation includes cleaning the airflow pipes. To do this,
open the lid on the top of the boiler (Figure 22 a) and then rotate (Figure 22 b) and lift
the tubes by the handle (Figure 22 c); repeat this procedure several times to shake
off the dirt accumulated inside the tubes.
a) b)
c)
Figure 22 – Cleaning the turbulators
Finally clean the interior of the boiler using a steel brush to remove the accumulated
dirt (Figure 23).
43
a) b)
Figure 23 – Cleaning the interior of the back boiler
Remove the burning basket (Figure 25 a) and ash tray (Figure 25 b) and vacuum
both pieces. You should also clean the boiler’s interior. To do so, open the lid, as
shown in Figure 26. When the cleaning is done, reassemble all parts performing the
above steps in reverse order and close the unit's door.

Figure 24 a) Burning basket; b) Ash tray
Figure 25 – Cleaning the burning basket
44
a) b)
Figure 26 – Cleaning the interior of the boiler
Additional cleaning
For every 1300-1700lbs (600-800kg) of pellets consumed, additional cleaning should
be performed.
For the back boiler, the procedure includes cleaning the air flow pipes and
turbulators. To do this, open the lid on the top of the unit (Figure 27 a), remove the
galvanized plate and the six wing nuts securing each turbulator set (Figure 27 b and
c). Then pull the turbulators up (Figure 27 d/e). Use a vacuum cleaner to clean this
area (Figure 27 f). Clean the interior of the tubes (Figure 27 g) using a steel brush
(Figure 27 g). The removed turbulators should also be cleaned using a steel brush
(Figure 27 h).
To reassemble the turbulators, perform the steps above in reverse order of the
figures below.
