Solzaima
Solzaima's vision has always been to provide a clean, renewable and more
cost-effective energy. This is why we've been dedicating ourselves for
more than 35 years to the manufacturing of biomass heating equipment
and solutions.
As a result of the persistence and unconditional support from our partner
network, Solzaima is today a leading player in the production of biomass
heating solutions, best illustrated by our backboiler fires for central heating.
We provide annually approximately 20000 homes with biomass heating
solutions. This market has been growing at an annual rate of 20% - a sign
that consumers are becoming increasingly aware of ecological and more
cost-effective heating solutions.
Solzaima is the only manufacturer in Portugal with ISO9001 quality
certification and ISO14001 environmental certification –we believe we are
a role model in this respect.
Technical Specifications
Free Standing Fires are designed to heat their surroundings. The M12-F

Your Unit
Fig. 1 –Free Standing Fires M20 and M12-F.
Components
* The combustion chamber and casing of all our Free Standing Fires are
made of top-quality carbon steel plate with a thickness of 0.1 inches (5mm)
and 0.019 inches (1.5mm), respectively.
3
The M12-F model includes a
stainless steel oven with a gas exhaust duct connected to the flue;
* The front panel and ash grate are made of grey cast iron.
* Heat-resistant ceramic glass. Can withstand temperatures of up to
1382°F (750°C) in continuous use;
* Heat-resistant paint for temperature peaks up 1652°F (900°C) and
operating temperatures in the order 1112°F (600°C);
Installation
Attention: all regulations and standards must be complied with when
installing this unit.
1. Combustion air and gas circulation
*This type of stove should be installed in well-ventilated areas. Any air
intake grilles should be placed in locations that are not liable to become
blocked;
3
The combustion chamber in models M20 and M30 has a thickness of 3mm.

* The combustion air enters the fire through the combustion air intake
damper on the front of the unit. This flow should be kept clear at all times;
* Additional air inlets may be needed if the stove is used in simultaneous
with other devices that require an air supply. The installer should evaluate
the situation according to the overall air flow requirements;
* Under normal operating conditions, the combustion gas flow should
create a draught of 12 Pa one metre above the throat of the flue. For
proper installation, at least 78.7 inches (2 metres) of metal flue tube with
the same diameter as the unit's smoke outlet should be fitted vertically
above the unit. After this section, sections of tubing with a maximum angle
of 45° may be used;
Figs. 2 and 3 illustrate correct and incorrect angles for installing a bend, if
required.
45º45º45º
45º45º
Fig. 2 –Correct angle for bends Fig.3 –Incorrect angle for bends
* A single-walled tube installed on the outside of a building results in the
condensation of water vapour in the combustion gases. Instead, use of a
double-walled, insulated tube is recommended;
* The flue outlet should allow for good air circulation and be placed at least
23.6 inches (60cm) above the top of any obstacle located within a distance
of 9.8 feet (3m);
* The ash grate should be installed with the narrow slots facing upwards;
* The same flue should not be used for more than one unit or open
fireplace. With shared chimneys, each flue should reach its outlet
independently and these should be at the same level to ensure that the air
circulation expels the gases;
* Brick chimneys should not be too wide, as the smoke will cool as it
disperses, reducing the draft. In case of draft problems, a revolving
chimney cowl can be installed;
2. Installation location requirements
* The unit should stand on a masonry hearth made of refractory bricks or
another type of non-combustible material;
* Combustible materials should not be installed close to the walls of the
stove;
* The floor on which the unit will stand must be able to support a
permanent load of 2.2 pounds (1kg)/cm ². If the load capacity of the floor is
insufficient, a solid plate can be used to distribute the load over an area
larger than the unit’s base;
* The building’s air intake grilles should not be obstructed;
9
10

* Ensure that the structure built into the wall is of an appropriate size to
house the unit;
* Materials/objects placed near the stove should be able to withstand the
heat radiated from the glass and walls, so should not be combustible;
* Refractory cement or other refractory material should be applied on the
chimney walls.
* The use of wood finishings may increase the risk of fire. Therefore, we
recommend the use of adequate insulation or that wood not be used at all.
3. Forced Ventilation and Circuit Diagram
* Units that are equipped with forced ventilation include two 9 W ventilators
that generate an air flow of 8 cubic mile (84m3) /h each, connected in
parallel through a thermostat according to the circuit diagram below.
Fig. 4 –Circuit diagram
Attention: all three wires in the power feed cable –earth, neutral and live –should be
connected. We take no responsibility for any damage resulting from non-compliance with this
warning.
* The electrical components should always be connected to the power
supply;

* The cable used for the electrical connection should be silicon-coated and
heat-resistant to 356°F (180°C). If the power feed cable is damaged, it
should only be replaced by a qualified technician;
* You should take care to not lay the cable where it may be crushed;
* The electrical installation should incorporate means to switch the unit off,
with a minimum separation of 0.118 inches (3mm) between the contacts,
pursuant to the applicable legislation in force.

Instructions for Use
Attention: all regulations and standards must be complied with when
installing this stove.
1. Fuel
* Only firewood should be used in this type of unit. It may not be used as
an incinerator, nor should other materials such as coal, painted wood,
varnishes, thinners, liquid fuels, glues or plastics be used. Also avoid
burning common combustible materials such as cardboard and straw;
* Exotic firewood should also not be used as fuel;
* The firewood should have low water content (less than 20%). We advise
that it should be placed in covered storage for around 2 years after felling,
in order to ensure efficient combustion and avoid creosote build-up in the
smoke duct, combustion chamber and on the glass; see Table 2, which
lists some of the types of wood that can be used in these units;
4
We recommend the use of a 30 mA differential switch and a 0.5 A circuit breaker for the unit’s
electrical installation.

1.1. Power
The power of your unit indicates its heating capacity, i.e. the energy your
unit transfers from the firewood to your home (usually measured in kW)
and is directly related to the amount of firewood that you place in it.
The rated output is the measure of a standard load of firewood when
tested in laboratories during a certain amount of time.
The power output is a manufacturer's recommendation from tests to the
equipment with firewood loads within a reasonable operation range. This
power output range will present different firewood consumptions per hour.
1.2. Energy Efficiency and Performance Ratings
Implementing solutions that seek to achieve greater energy efficiency
allows for substantial reductions in energy needs, and thus reduces our
current dependence on fossil fuels and other non-renewable sources of
energy.
Energy efficiency enables you to make large savings from both an
economic and an environmental point of view.
As a result of Solzaima's commitment towards the equipment's efficiency,
most of our products are classified as efficiency class 1, i.e., with an
efficiency rate equal to or greater than 70%.
A 70% efficiency rate means that 70% of the energy contained in the
firewood is used to warm your home or, in other words, you are able to
produce the same amount of energy with much less firewood.
*in accordance with EC classification standards for insert fires.
A Solzaima 5kW unit with an efficiency rate of 75%, i.e. efficiency class 1,
will consume approximately 3.5 pounds (1.6kg) of firewood per hour to
warm a 389 sq ft room (35m2).
Typically, a traditional fireplace has an efficiency rate of approximately
10%, which means it will consume about 26.5 pounds (12kg) of firewood to
produce the same 5kw necessary to warm the same 389 sq ft room
(35m2).

2. First Use
* Ask the installer to light the unit to ensure that all is functioning correctly;
* The stove’s paint is cured by the heat when it is first used, which may
give rise to additional smoke. If this happens, you should ventilate the
room by opening external windows and doors.
3. Normal Use
* Lighting:
a) Open the flue damper completely –lever on the top right-hand
side of the unit (where applicable);
b) Place some pine cones (preferably) on the ash grate;
c) Place some kindling wood on top, piled horizontally;
d) Open the combustion air intake regulator;
e) The lighting period is over when the body of the unit has
reached a constant temperature. You should then regulate the combustion
air intake;
* You should check that there is sufficient ventilation in the room where the
unit is installed, otherwise it will not work properly. For this reason, you
should check if there are any other heating devices which consume air
during operation (e.g. gas-fired equipment, braziers, etc). We recommend
against using these devices all at once;
* The air for combustion is drawn from the surrounding room, consuming
oxygen. You should check that ventilation grilles and other devices for
allowing air to enter from outside remain unobstructed;
* You must open the flue damper (where applicable) before reloading the
stove with firewood. First, open the flue damper completely, then wait a
little while to allow a good draught, and only then open the door slowly to
prevent drawing smoke out into the room;
17
18

* You should only open the door during reloading. Normal conditions of
use require the door to remain closed;
* Reload before the previous load has burnt completely, in order to make it
easier for the combustion to continue;
* Use of the unit is not recommended when weather conditions are so bad
that the draught is seriously affected (particularly when there are very
strong winds).
4. Safety
* The ventilators should always be connected to the power supply (where
applicable);
* You should take care to not lay the cable where it may be crushed;
* The exposed metal parts reach high temperatures - 212°F (100°C) on the
door and 140°F (60°C) on the frame. The door handle does not reach
temperatures above 113°F (45°C). Do not touch the hotter areas;
* You should use a glove or other protection if you have to touch the unit
when it is in operation;
* In case of fire in the flue, immediately close the door, flue damper
(where applicable) and air intake;
* If there is a power cut, resulting in the ventilators cutting out when the
unit is in operation, close the combustion air intake and do not load the unit
with any more firewood. Keep the door closed;
* We recommend you only use spare parts supplied by the manufacturer –
SOLZAIMA.
5. Cleaning and Maintenance
* You should remove ash from the drawer on a regular basis (after the unit
is switched off), so that the combustion air can enter through the ash grate
unobstructed;
* The window should be cleaned with a suitable product,
5
by following the
instructions for use and not allowing the product to come into contact with
the sealing string and painted metal parts, which could initiate oxidation.
The sealing string is glued; therefore it should not be moistened with water
or cleaning products. If it becomes detached, it can be reattached with
contact glue after cleaning the groove with fine sandpaper;
* You should not clean the cast or plate iron parts with detergents. These
should be cleaned with just a dry cloth to remove the dust and you may
treat the cast iron parts with a special polish
6
as often as you feel
necessary.
* We advise you to clean the flue and flue throat (at the exit of the unit) at
least once a year. This can be done by removing the baffle plate
(removable plate in the ceiling of the combustion chamber);
* If you do not use the unit for a prolonged period, check to make sure that
the flue pipes are clear before lighting it;
5
Seek advice from your installer.
