This manual is provided with the product. Please keep it close to the unit.
2.1. For your safety, we recommend that:
Make sure you fully read and understand this instruction manual before using the free-
standing pellet fire as a biomass heating unit;
•Make sure that the hydraulic circuit was correctly assembled and connected to the
water supply before turning on the free-standing pellet fire;
•The free-standing pellet fire is not intended for use by children or persons with
reduced physical, sensory or mental capabilities, or lack of experience or knowledge,
unless they are under supervision or have been instructed concerning the use of the
unit;
•Do not touch the free-standing fire when barefoot or if any part of your body is wet
or humid;
•Do not tamper with safety or adjustment features without the manufacturer's
authorization;
•Do not cover or reduce the size of the vents at the installation area;

3
•The free-standing pellet fire requires a clear space around the unit for proper
combustion, so possible air tightness of the location or any existing air extraction
sources in the room may prevent the unit proper operation;
•The existence of vents is a requisite for proper combustion;
•Do not leave the packing materials near children;
•During normal operation, Free Standing Fire unit's door must not be opened;
•Some parts of the unit may overheat during normal operation, so avoid direct
contact with parts such as the door handle and glass;
•Check the existence of any obstructions on the fume duct before turning on the
unit after a long period of inactivity;
•This free-standing pellet fire unit is intended for residential use in protected areas.
Safety systems may turn off the unit. If this occurs, contact the technical assistance.
In any circumstances should you attempt to interfere with the safety systems;
•The free-standing pellet fire is a biomass heating unit equipped with an electric
fume extractor. The occurrence of any power failure during its use may prevent fume
extraction and the room will be filled with smoke. For this reason, you should have a
natural fume extraction system, like a chimney, available;
•Solzaima offers you an optional safety system which allows the Free-Standing Fire
unit to be connected to a UPS so that during any power failure the fume extractor will
still operate until complete extraction of all the fumes;
•If you intend to use the Free-Standing Fire unit while you are away from home or
unattended, you should use the safety system specified above for total safety during
any power failure;
•During operation, NEVER turn off the free-standing fire unit by disconnecting the
electric plug. The fume extractor on the free-standing pellet fire unit is electric so
disconnecting the power plug will prevent the extraction of combustion fumes;
•Your unit must be disconnected from the mains for servicing. Before doing this, the
unit must be totally cooled down (if operating before);
•Never touch the interior of the unit without disconnecting it from the power mains;
•On back boiler models, the maximum temperature of the water that can be set by
the user (water set-point temperature) is 85°C. In the event of a temperature of 90ºC
being reached, the free-standing pellet fire unit automatically disconnects and the
respective alarm is activated.

3. Advice on action in the event of a fire in a chimney
(includes equipment)
Try to extinguish the fire without putting your life at risk.
•If within a minute you cannot extinguish the fire, you should call the fire
department.
•Close the doors and windows or partition where the fire has flared.
•Disconnect the electric current and close the gas before leaving your home.
•Once outside, you must wait for the firefighters and be ready to give you the
following information: location of the fire, possible materials that are burning and what
they can do to prevent the progression of fire.

5. Installing the free-standing pellet fire
Before installing, please perform the following steps:
•Upon reception, check the product for completeness and to determine that is does
not show any damage signs. Any damages or defects should be checked before the
unit is installed;
•The unit is equipped with four adjustable height feet at the base which allow for a
simple regulation when installed on a non-flat surface;
Figure 8 - Adjustable feet
•Remove the instruction manual from the package and hand it over to the client;
•Connect an 80mm wide (Hidro 12) or 100mm wide (Hidro 17 or Hidro 23) duct
between the combustion gas output and the outgoing fume extraction duct of the
building (e.g., chimney) – check diagrams point 5;
•If a tube is used for combustion air inlet from the outside, it shall be no longer than
60cm horizontally or present offsets (such as bends);
•Perform the hydraulic installation;
•Connect the 230VAC power cable to a grounded socket;
•The surface of the unit where the hot air outlet is located must be facing the area
to be heated;
•The unit's remote control has a programmable thermostat. As an option, a
conventional external programmer may be used (not included) to automatically setup
the unit's operating periods. This should be connected through cable to the optional
230VAC programmer plug (not provided).

5.1. Installation requirements
The minimum distance between the free-standing pellet fire unit and particularly
flammable surfaces is specified in Figure 9. The top of the unit must be at least 100cm
separated from the ceiling, especially in rooms with ceilings consisting of flammable
materials. The base supporting the unit cannot be made of combustible material (e.g.,
carpet), so make sure you use an adequate protection.
a) b)
Figure 9 - Minimum distances from all surfaces: a) upper view of the unit's installation; b) side view of the unit's
installation
WARNING!
Keep combustible and flammable materials at a safe distance.
5.2. Installation of ducts and fume extraction systems
• The exhaust pipe must have been designed for this purpose, in compliance to the
location requirements and in accordance with any applicable regulations.
• Important! An inspection-T with an airtight lid must be attached to the exhaust
pipe of the unit to allow the regular inspection of the system or discharge of heavy
dust and condensates.
• As indicated in Figure 9, the exhaust pipe must be assembled so as to allow cleaning
and maintenance of the pipe by inserting inspection points.
• Under normal operating conditions, the combustion gas flow should create a draught
of 12 Pa one meter above the chimney neck.

11
• The unit must not share the chimney with other equipment.
• Pipes outside the operating area must have double stainless-steel insulation and an
internal diameter of 80 mm (Hidro 12) or 100 mm (Hidro 17 and Hidro 23).
• The fume exhaust pipe may generate condensation, so we recommend that
the appropriate systems for collecting condensates should be installed.
5.3. Installation without a chimney
The installation of the free-standing pellet fire without a chimney should be performed
as illustrated in Figure 10, equipped with an exhaust pipe (with a minimum diameter
of 80 mm for the Hidro 12 and 100 mm for the Hidro 17 and Hidro 23 model)
directly outside and over the roof.
Double-walled stainless steel insulated pipes must be used and properly fastened to
avoid condensation.
A T-tube must be installed at the base of the pipe to allow periodic inspections and
annual maintenance, as illustrated in Figure 10.
Figure 10 - Side view of the installation without a chimney, illustrating the inspection point
Inspection

12
Figure 11 specifies the basic requirements for installing the chimney to the unit.
a)
b)

13
c)
Figure 11 - Examples of standard installations
Failure to comply with these requirements may prevent the correct operation of
the unit. Follow all the instructions presented on the diagrams.
The Hidro units operate with the combustion chamber in vacuum, so it is
absolutely necessary to have a fume exhaust pipe to extract combustion gases
properly.
Fume duct material: The tubing must consist of 0,5 mm thick rigid stainless steel,
with fastening joints attaching the different sections and accessories.
Insulation: The fume ducts must be double-walled and insulated to make sure that
fumes do not cool down going outwards, which would cause an inadequate circulation
and condensation that may damage the unit.
Output “T-tube”: Always attach to the output of the unit a “T-tube” with a regulator.
Windproof terminal: A windproof terminal must always be installed to avoid the
backflow of fumes.

14
Draught in the chimney: The figures below show three standard diagrams,
specifying adequate lengths and diameters. Any other type of installation must
guarantee a draught of 12 Pa (0,12 mbars) measured when hot and at the maximum
power.
Ventilation: To get the optimum operation of the unit it is necessary that the
installation location has an air inlet with a minimum section of 100 cm2,
preferably near the back panel of the unit. The free-standing pellet fire unit has a
circular pipe ( 50mm) that may be connected to the exterior of the house.
If the residence has an air exhaust system installed (e.g., kitchen extractor
fan), a top ventilation section must be installed, suitable to accommodate the
different air exhaust units’ systems that exist in the house.
The installation of the unit on locations near kitchen exhaust fans or fume
extractors may prevent the unit from operating properly.
5.4. Installation with a chimney
As shown in Figure 12, the unit is installed with an exhaust pipe (80 mm for the
Hidro 12; 100 mm for the Hidro 17 and Hidro 23) directly on to the chimney. If
the chimney is too large, an 80 mm-wide pipe should be installed at the fume outlet.
A T-tube must be attached to the base of the pipe to allow for periodic inspection and
annual maintenance, as illustrated in Figure 12.
