2. THEORETICAL NOTIONS FOR THE INSTALLATION
2.1. PELLETS
The pellet is obtained by processing the sawdust produced during working wood and timber (dried wood and paint free).
The compactness of the material is guaranteed by the lignin which is contained in the wood itself and allows the
production of pellets without the 'use of glues or binders.
The market offers different types of pellets with characteristics that vary based on mixtures of wood used. The diameter
varies between 6 and 8 mm, with a standard length between 5 and 30 mm. The pellets of good quality has a density
ranging from 600 to more than 750 kg / m3 with a water content that is maintained between 5% and 8% of its weight.
In addition to being an environmentally friendly fuel, as you push the limits of wood residues resulting in a
cleaner- burning than that produced with fossil fuels, the pellets also have technical advantages. While a good wood
has a calorific value of 4.4 kW / kg (15% RH, after 18 months of seasoning), the pellet is 4.9 kW / kg.
To ensure good combustion, and no power problems, it is imperative that the pellets are stored in a dry place,
protected from dirt, and the thermos-stove is placed in a place where the conditions are the same, not to generate the
same type of problems on the power pellets in the tank. The pellet is usually supplied in 10, 14 or 15 kg bags, so
storage is very handy.
A good quality pellet ensures good combustion lowering harmful emissions into the atmosphere.

If the fuel is poor , the more often cleaning inside the grate and the combustion chamber will be
required .
K-Stove strongly recommends using certified fuel in its stoves (EN-A1 Plus).
The use of fuel of inferior quality or not conforming to the specification given above compromises the
running of your stove and can therefore lead to the termination of the guarantee and of the manufacturer's
responsibility for the product.
K-Stove pellet stoves run exclusively on pellets with a diameter of 6 mm (European countries) with lengths.
IMPORTANT!
Installation and assembly of the stove must be carried out by qualified personnel.
The stove must be installed in a suitable position to allow the normal operations of opening and ordinary maintenance.
The site must be:
capable of providing the environmental conditions for operation
equipped with power supply 230V 50 Hz
capable of taking an adequate system for smoke discharge
provided with external ventilation
provided with an earth connection complying with CEI
The stove must be connected to a flue pipe or an internal or external vertical duct conforming to current
standards UNI 7129 - 7131 9615. The stove must be positioned in such a way that the electrical plug is
accessible.
IMPORTANT!
The stove must be connected to a flue pipe or a vertical duct which can discharge the fumes at the
highest point of the building. The fumes are however derived from the combustion of wood products, and if
they come into contact with or close to walls, they can make dirty marks. Also take care because the fumes
are very hot but almost invisible, and can cause burns on contact. The holes for the passage of the smoke
pipe and for the intake of air from outside should be made before positioning the stove unit.
2.3. OPERATING ENVIRONMENT
For proper operation, and a uniform distribution of temperature, the stove
should be placed in a location with an air flow that guarantees the air
needed for combustion of the pellets (should be available approximately 40
m³ / h) according to the installation and the second regulations in the
country.
The volume of the environment must not be less than 30 m³.
The air must enter through permanent openings on the walls (near the stove) with
a minimum of 100 square centimeters.
These openings must be made so that they cannot be obstructed in any way, and
allow proper airflow. Air can also be taken to ventilate rooms adjacent provided
they are equipped with air hose and are not used as a bedroom and bathroom, or

PELLET BURNING STOVES INSTALLATION & MAINTENANCE MANUAL

where there is no fire hazard such as: garages, sheds, storage of combustible materials, etc., strictly complying with
the requirements under current rules. It is absolutely prohibited to installation the stove in bedrooms, bathrooms, and
where it is already installed another d heating device without adequate airflow (fireplace, stove, etc..).
It is expressly prohibited the placement of the stove in environments with
explosive atmospheres. The floor of the room where the stove will be installed must be
sized appropriately to support the weight of the stove itself (which should be
considered in addition to the weight of the machine said the same load must be added
a maximum of 60 kg for the pellets, and 80 kg for water). When installing , keep a
minimum distance from obstacles and not flammable (B) of 25 cm the rear to, lateral
(LR) of 25 cm and anterior (C) of 80 cm. In the presence of objects believed to be
particularly sensitive such as furniture, curtains, sofas, carpets, etc., greatly increase the distance of the stove from
them. In the presence of wooden floor floor- prepare the plan and in accordance with
rules in force in the country, on fire prevention .
2.4. CONNECTION TO THE EXTERNAL AIR INTAKE
It is essential that the room where the stove is installed , the stove can avail of an
air flow in sufficient quantity as it is required by the regular combustion equipment
and ventilation. This can be done by means of permanent openings on the walls
that give the room to be ventilated to the outside, ventilation ducts or through
individual or collective. Within this scope , the outer wall near the stove must have
an opening minimum 100 cm ², protected by a grid inside and outside. The air
intake must also:
• be communicating directly with the installation environment
•be protected by a grate, wire mesh or other suitable protection, provided it does
not reduce the minimum section.
• position in a suitable manner as to prevent it from being obstructed in any way
It is prohibited to connect the air directly to the stove (communicating
directly from the outside), to avoid compromising thermodynamic performance,
however it is required that the conditions still guarantee about 50 m³ / h of air
replacement, as provided in the current UNI 10683 .
2.5. CONNECTION OF SMOKE DISCHARGE PIPE
When making the hole for the flue pipe it must be taken into account the possible
presence of inflammable materials. If the hole has to go through a wood wall or
other thermo labile material , the installer MUST use the Industrial insulated pipe
(with min thermal conductivity of 0.07 W / m ° K). The same applies if the stove pipe
must go vertical or horizontal sections remain near (min.20cm) to a heat- labile wall.
The combustion chamber works in depression, so the exhaust duct for the exhaust
fumes will be linked to depression when effective chimney as prescribed.

PELLET BURNING STOVES INSTALLATION & MAINTENANCE MANUAL

It should always use pipes and fittings with appropriate seals to ensure air‐tightness in order to avoid
possible harmful CO fumes into the environment.
All sections of the exhaust duct must be inspect able and removable to allow for periodic cleaning of
the interior, which is necessary for the proper functioning of the system (T-piece with inspection). Position the
stove strict accordance with all regulatory requirements and attention to highlighted date.
Important:
All changes direction 90 degrees of the flue gas channel must be prepared if possible with the appropriate
fittings to "T" with inspection. It is absolutely forbidden to use a net at the end of the hose as it can cause
serious problems for the proper and safe operation of the stove.
In connection do not use the chimney sections of pipe horizontally, but always the same place at an angle of
5° minimum to rise, possibly avoiding the use of a 90° (you can use up to 3), and use preferably 45 ° curves. It
is recommended to not use a total length of the pipe diameter 80 mm, greater than 6 m in total.
2.6. CONNECTION TO THE CHIMNEY
The chimney must have inside dimensions of no more than cm. 20X20 or 20 cm
diameter. In the case of larger or poor condition of the chimney (ie: cracks, poor
insulation, etc.) it is recommended to insert stainless steel tube in the chimney
of a of suitable diameter for its entire length, to the very top. Check with
suitable instruments that there is a minimum draft. Guaranteed 15 Pa. At
the bottom of a chimney inspection for periodic inspection and cleaning, which
must be done annually. You must ensure that a chimney top is installed
according to regulations for wind force.
This type of connection must guarantee of 15 Pa, allows the correct discharge
of smoke with a natural draft even if there is no electricity.
2.7. CONNECTION TO AN EXTERNAL FLUE PIPE WITH
ISOLATED OR DOUBLE WALL
The external pipe must have minimum internal
dimensions of cm. 10X10 or 10 cm diameter. cm, and maximum. 20X20 or 20 cm
diameter. Check with appropriate tools that there is a draw of 10 Pa. It
must use only, and only pipes insulated (double wall) within the smooth stainless
steel (stainless steel flexible tubes are not allowed) fixed to the wall, to prevent,
and / or minimize condensation problems. At the bottom of the outer vertical duct
an inspection tap for periodic inspections and cleaning to be done annually. You
must ensure that the chimney is installed according to wind force.
This type of connection, even in case of momentary power
failure, ensuring the evacuation of the fumes.
2.8. CONNECTION TO THE FLUE PIPE
