3. Safety precautions
Solzaima will not assume any responsibility if the precautions, warnings and
operating standards of the equipment are not respected.
The equipment manufactured by Solzaima is simple to operate and special attention
has been given to its components in order to protect the user and the installer
against possible accidents.
The installation must be done only by authorized persons, who must deliver to the
buyer a declaration of conformity of the installation, and who will be totally
responsible for the final installation, and consequently, for the good functioning of
the product.
This equipment must be intended for the use for which it was expressly
manufactured. All contractual or extra-contractual liability of the manufacturer is
excluded if it causes injury to persons, animals or things, due to installation errors,
maintenance errors or improper use.
After you have removed the packaging, make sure that the contents are complete
and undamaged. If the contents of the packaging do not correspond to those
indicated in point 1, contact the dealer from whom you bought the device.
All the components that make up the equipment guarantee its operability and
energy efficiency and must be replaced with original parts by an authorized service
center.
The maintenance of the equipment must be performed at least once a year, for this
you should contact your specialized installer.
This instruction manual is an integral part of the product. Make sure you are always
near the device.
3.1. For your safety, we recommend that:
•The compact pellet 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 compact pellet;
•The compact 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;

4
•Do not touch the compact when barefoot or any part of your body is wet or
humid;
•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 compact pellet 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 compact'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 compact pellet 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 compact pellet 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;
•REDPOD offers you an optional safety system which allows the compact 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 compact fumes;
•If you intend to use the compact 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 compact pellet by unplugging the power
cord from the wall socket. The fume exhaustion system on the compact pellet is
power-operated so disconnecting the power plug will prevent the exhaustion of
combustion fumes;

5
•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 compact when connected to the power mains;
••For this compact, the maximum setting for the water temperature that can
be specified by the user (water set-point temperature) is 80°C. If a temperature of
90ºC is reached, the compact automatically turns off causing the corresponding
alarm to go off.
4. Advice in case of a chimeny fire (including the
equipment)
•Put the fire out without endangering your life;
•If you cannot put out the fire within one minute, call the fire department;
•Close the doors and windows or the room where the fire occurred;
•Turn off the electricity and gas before you leave home;
•Once outside your home, provide information that will help put out the fire, such
as: location of the fire and materials that are burning.

6. Compact pellet installation
Before starting the installation, perform the following actions:
•Check immediately upon receipt that the delivered product is complete and in
good condition. Any defects must be reported before installing the appliance.
•The compact has four height-adjustable feet at its base, allowing a simple
adjustment on uneven floors.
Figure 7 - Adjustable Feet
•Connect a 100 mm diameter pipe in compacts between the flue gas outlet
and a flue for exhausting fumes to the outside of the building (e.g. chimney) -
check diagrams in Section 6.3.
•If a pipe is used for combustion air intake from outside, it must not be longer
than 60 cm horizontally or contain disturbances (e.g. bends).
•Carry out hydraulic installation (see point 20).
•Connect the 230VAC supply cable to an earthed electrical socket.
•The machine is equipped with a chrono-thermostat on the control panel. As
an option, a conventional external programmer (not included) can be used to
automatically set the device's operating periods.
6.1. Installation requirements
The minimum distances of the pellet stove from particularly flammable surfaces are
shown in Figure 8.
On top of the pellet stove, a minimum distance of 100 cm from the ceiling of the
room must be maintained, especially if the ceiling contains flammable material. The
base of the compact must not be made of combustible material, (e.g. carpeting), so
there must always be adequate protection.

10
a) b)
Figure 8 - Minimum distances from all surfaces: a) top view of the equipment installation; b) side view of the
equipment installation
WARNING!
Keep combustible and flammable materials at a safe distance.
6.2. Installation of ducts and Smoke exhaustion systems
•The construction of the gas exhaust pipe must be suitable for the purpose
according to the requirements of the site and in compliance with the regulations in
force.
•Important! A T-inspection with a tight-fitting lid must be inserted at the outlet of
the compact pellet exhaust pipe to allow for regular inspection or discharge of
heavy dust and condensate.
•As shown in Figure 8, the exhaust ducting should be made so that cleaning and
maintenance are ensured by inserting the inspection points.
•Under nominal operating conditions, the flue gas draft must give rise to a
depression of 12 Pa, measured 1 meter above the chimney neck.
•The compact must not share the chimney with other equipment.
•The pipes outside the place of use must be double-insulated stainless steel, with
an internal diameter of 100 mm.
•The smoke exhaust pipe, can generate condensation, in this case it is
advisable to establish adequate condensate collection systems.

11
6.3. Installation without chimney
The installation of the pellet stove when there is no chimney must take place, as in
Figure 9, by bringing the smoke exhaust pipe (with a minimum internal diameter of
80 mm for the air version and 100 mm for the water version) directly outside and
above the roof.
Properly anchored double-walled insulated stainless steel pipes should be used to
prevent condensation phenomena.
Provide at the base of the pipe a T for periodic inspections and annual maintenance,
as exemplified in Figure 9.
In Figure 10, the basic requirements for the installation of the compact chimney are
represented.

Figure 10 - Examples of type installations
Failure to comply with these requirements will jeopardize the correct operation
of the compact. Comply fully with the indications on the diagrams.
The compacts operate with the combustion chamber in a depression, so it is
absolutely necessary to have a smoke evacuation duct that extracts the combustion
gases properly.
Smoke duct material: The pipes to be installed must be rigid, of stainless steel
with a minimum thickness of 0.5 mm, with joints for joining the different sections
and fittings.
Insulation: Smoke ducts must be double walled with insulation to ensure that the
smoke does not cool down during its journey to the outside, which would cause
inadequate draft and condensation that can damage the appliance.
Output "T”: Always use a "T" with registration at the compact outlet.

14
Antivento Terminal: An anti-vent terminal should always be installed to prevent
the return of fumes.
Chimney Depression: The figures illustrate three type layouts, with the
appropriate lengths and diameters. Any other type of installation must ensure that
a depression of 12 Pa (0.12 mbar) measured hot and at maximum power is
generated.
Ventilation: For the compact to work properly, the place where the appliance
is installed must have an air inlet with a minimum section of 100 cm2,
preferably near the back of the compact. The compact has a round tube
(50 mm) that can be connected to the outside of the house.
If there is an air extraction system in the home (kitchen extractor), it is necessary
to have a ventilation section that is larger and better sized than the various pieces
of equipment that extract air from the home.
Placing the compact in places where kitchen extractors or gas extractors are
installed may affect the proper operation of the compact. It is recommended that
the compact is switched off when these extractors are in operation.
6.4. Chimney installation
As shown in Figure 11, the compact pellet installation brings the 100 mm diameter
flue pipe directly to the chimney. If the chimney is too large, it is recommended to
pipe the flue outlet with a minimum internal diameter pipe of 100 mm.
Provide at the base of the pipe a "T" for periodic inspections and annual
maintenance, as illustrated in Figure 11.

15
Figure 11- Side view of the chimney installation, with example of the inspection point
When atmospheric conditions are so adverse as to cause strong disturbance to the
compact's fumes draft (in particular very strong winds), it is advisable not to use
the compact.
If the equipment is not used for a long period of time, the user must ensure that
there is no blockage in the chimney pipes before lighting.
