Pellet properties
The appliance has been tested with all types of pellets available on the market. The pellets must have the following
properties:
-Diameter 6 mm.
-Maximum length 35 mm.
-Maximum humidity content 8–9 %.
-Made of 100% wood. Totally additive-free.
-Maximum ash residue 1.1 %.
To obtain optimal efficiency from the appliance, we recommend using good quality pellets. Pellets should be poured
into the tank using a shovel, and not directly from the bag.

12
SOFT 80, SOFT 100 PELLET-BURNING STOVE
EN - Rev. 1.0
Good quality pellets should have the following properties:
-Constant-diameter cylinders with a smooth, shiny surface;
-Low amount of sawdust inside the packages;
-After grabbing a bunch of pellets and placing them into a container filled with water, good quality pellets will sink and
poor quality ones will tend to float;
-The quality certification data, in particular conformity to international standards such as EN14961-2, DIN 51731 and O-
NORM M7135, should be indicated on the packaging;
-The packages should be intact since pellets tend to absorb humidity. Humidity not only reduces the calorific value and
increases the amount of flue gases expelled, but also causes swelling of the product which may create problems with
the appliance.
The production of pellets must comply with international standards (such as EN14961-2, DIN 51731 and O-NORM
M7135) which define minimum values for checking pellet quality. To facilitate the right choice of the combustible
material, we indicate below one of the most common certification marks identifying pellet quality:
The use of poor quality pellets or any other material can damage the appliance’s operation, voiding the warranty
and exempting the manufacturer from all liability.
In order to guarantee trouble-free combustion, the pellets must be stored in a dry place.
REQUIREMENTS OF THE PLACE OF INSTALLATION
Positioning
The initial phase for best installation of the appliance is to determine its optimum location; the following elements need to
be considered:
-The possibility of creating an external air vent;
-The possibility of creating a straight flue, preferably coaxial to the outlet of the appliance;
-Ease of access for cleaning the appliance, the flue gas exhaust pipes and the flue.
The unit must be installed on a floor with a suitable load capacity. If the existing building does not fulfil this requirement
appropriate measures (e.g. load distribution plate) must be taken.
The minimum safety distance from flammable materials must be at least 200 mm from the sides and 800 mm
from the front of the appliance.
Relocating the appliance should not be done by forcing on the handle, glass or ceramics.
The installation must guarantee easy access for cleaning the appliance, the flue gas exhaust pipes and the flue, and any
subsequent maintenance operation by the Authorised technical assistance centre.
Once you have found the best location for the appliance, position it following the instructions given below.
The appliance must not be installed in small rooms, bedrooms, bathrooms or in areas with an explosive atmosphere.

EN - Rev. 1.0
Spaces around and above the appliance
The figure below shows the minimum distances from walls or other not-easily-removable furniture, that need to be taken
into consideration when positioning the appliance.
Any shelves or false ceilings mounted above the appliance must be at least 150 cm away from the top part of it.
Furniture and movable objects made from flammable materials must be positioned at least 50 cm from the side surfaces
of the appliance; these objects must be moved when performing maintenance on the appliance.
Protect all structures that can catch fire against the radiated heat of the fire.
External air intake
During operation, the appliance takes in air from the environment in which it is installed; It is therefore essential that this
air is replaced through an external air vent. The absence of the air vent may affect the flue draught and therefore the
combustion and the safety of the appliance.
Therefore it is mandatory to install an external air vent with a minimum completely free passage of at least 80 cm2
(round hole with minimum diameter of 15 cm protected with a special fixed large mesh grid).
If the wall behind the appliance is on the outside, we recommend you make the hole near it at about 20 cm above the
ground (see example in Fig. A).
If it is not possible to put an air vent in the wall behind the appliance, make a hole in a perimeter wall in the room where it
is installed. If it not possible to put the external air vent in the same room as where the appliance is installed, this hole
can be made in an adjoining room as long as this room communicates permanently, by means of a transit hole (15 cm
minimum diameter).
The hole must be protected externally with a fixed grille. The protective grille must be checked periodically to ensure that
it is not obstructed, thereby impeding the passage of air. Therefore keep the air vents clear of obstructions.
The UNI 10683 Standard FORBIDS the drawing of combustion air from garages, warehouses storing combustible
materials, or from business premises with a fire hazard.
If there are other heating or extraction devices inside the room, the air vents must guarantee a sufficient amount of air for
properly operating all the devices.
Only sealed appliances (e.g. C type gas appliances, according to the UNI 7129 Standard) or appliances that do not
cause a lower pressure compared with the external environment can pre-exist or be installed in the place where the
appliance is installed.
Extractor fans can cause malfunctions to the appliance if used in the same room.

SMART 120 PELLET BOILER COOKER
14
EN - Rev. 2.2
Do not connect the external air vent directly to the appliance through piping. If there are other heating or extraction
devices inside the room, the air vents must guarantee a sufficient amount of air for properly operating all the devices.
Only sealed appliances or appliances that do not cause a lower pressure compared with the external environment can
pre-exist or be installed in the place where the appliance is installed.
Extractor fans can cause malfunctions to the appliance if used in the same room.
Figura A
Chimney and Flue pipe
The chimney is essential to the efficient operation of a Klover appliance. The chimney should be designed and
constructed according to these instructions, and relevant regulations including Building Regulations Approved Document
J.
Shape and size of chimney: A round chimney of 125mm diameter is recommended. 125mm is also the minimum
diameter which should be used. If the appliance is DEFRA Exempt then it should be connected to a 125mm chimney as
standard (assuming that the outlet is not larger than 125mm). If it is not DEFRA Exempt then a calculation according to
BS EN 13384-1:2002 must be completed if it is to be connected to a 125mm diameter chimney.
The maximum recommended round chimney diameter is 150mm.
Square or rectangular cross-sections must have rounded corners with radius not less than to 20 mm Rectangular cross-
sections must have a maximum ratio of 1.5 between the sides.
The chimney must have a constant, and unobstructed, internal cross section
Under no circumstances should the chimney be of a smaller diameter than the appliance outlet.
Connecting flue pipe: Short runs of single skin flue pipe to connect to the chimney may be run in a (minimum) diameter of
100mm (as long as this is not smaller than the appliance outlet).
Existing chimneys: Existing masonry chimneys should be lined with flexible stainless steel liner and the liner should be
insulated. All connections must be appropriately sealed.
Existing chimneys must be inspected, be clear of obstruction and have been swept clean immediately before installation
of the lining system.
No shared chimneys: Each appliance must connect to its own flue. No other appliance must connect to the same flue or
chimney. No other pipes or conduits must pass through the chimney or flue.
Sealed joins and connections: The appliance works with the combustion chamber in negative pressure and the flue pipe
under positive pressure; it is essential that all joints and flue and chimney connections are sealed. Single skin and twin
wall flue pipe should incorporate silicone seals at each joint. Other connections should be sealed with a suitable sealant
(for example high temperature silicone). All seals must be able to withstand 250ºC or more.
Suitable materials: Flue and chimney products used, including fixings and components, must be made of suitable, non-
combustible materials conforming to the applicable regulations.
Aluminium and fibre cement pipes are forbidden.

EN - Rev. 2.2
Orientation and initial vertical rise: The flue system should run as vertically as possible as any deviations off the
vertical can adversely affect the draw. 45º is the maximum off-vertical angle than may be used. Non-vertical sections
should make up no more than ¼ of the effective height of the flue or chimney (measured from the appliance outlet to
the top of the chimney), and must not be longer than 2,000 mm.
There should be no more than 4 bends in the system, with a tee counting as 2 bends.
Securely fix and support the system to avoid vibration and movement.
90º bends should not be used. When using the rear outlet on the appliance a 90º tee should be used with sweeping
access and debris collection space.
When using the rear outlet any horizontal run should not exceed 150mm, including the arm of the tee.
An initial vertical run of 600mm from the appliance is recommended before any change in direction.
Cleaning Access: The system must provide access so that the entire system can be swept and cleaned.
Flue pipes must not pass through rooms in which the installation of combustion devices is prohibited.
IT IS STRICTLY FORBIDDEN TO INSTALL FLUE DAMPERS/BUTTERFLY VALVES.
Heat shielding: If combustible materials are present then minimum separation distances will need to be adhered or
heat shielding will be required. Please refer to Building Regulations Approved Document J, and also these installation
instructions.
