Types of wood
Wood is one of the most precious materials offered by nature. For heating purposes, it must be verified that the features
of the wood satisfy some important requisites that must not be ignored, the most important of which is without a doubt
the correct seasoning or drying, in other words the wood must have the correct amount of humidity, around 10-15%,
therefore also the period of the year in which it is felled becomes important. This should coincide with the winter period.
Correct seasoning (at least 2 years) provides fuel with an excellent yield that is not very pollutant.
It must be kept in covered, well-aired places, already cut into pieces of a suitable size for the appliance.
The wood is divided into softwood and hardwood on the basis of the weight kg of a cubed metre of material. Softwoods
weighing 300-350 kg/m3 include fir, pine, poplar, European alder, chestnut and willow, while hardwoods weighing 350-
400 kg/m3 include beech, ash, elm, acacia and oak.
Softwood ignites easily, burns quickly, produces a long flame and is used in ovens requiring a long flame pass.
Hardwood is more compact, the combustion is slower with short flame, it lasts longer and is more suitable for domestic
central heating.
The wood to be burned for heating purposes has different features according to the plant variety from which it is
obtained. Not all woods are equal, and the drying time and the calorific value vary from plant to plant. The calorific value
depends on the humidity and density of the wood. Top quality woods are beech, ash, elm and acacia. Avoid resinous
woods as they reduce the appliance's service life.
Resinous woods generate a lot of soot and require the flue and the appliance to be cleaned more frequently. The
calorific value of the different types of wood depends greatly on their humidity and consequently the power of the

WOOD BURNING BOILER COOKER ALTEA 110 SICURO TOP
11
EN - Rev. 1.2
appliance is directly affected by the type of wood used, on average a well-seasoned wood has a calorific value of 3200
kcal/kg.
Calorific value of wood in relation to humidity:
CALORIFIC VALUE of the wood means the amount of heat yielded during combustion, referring to the unit quantity of
the material burned.
The calorific value of a wood species depends on the presence of lignin (6000 Kcal/kg) or cellulose (4000 Kcal/kg) as
well as the abundance of resin (8500 Kcal/kg).
The calorific value per unit of weight ( = absolute) is highest in Conifers.
-Absolute calorific value of conifers: 4700 Kcal/kg
-Absolute calorific value of broad-leaved species: 4350 Kcal/kg.
On the other hand the SPECIFIC WEIGHT of the “broad-leaved species” is greater; therefore with equal volumes
introduced into the appliance, both the weight and amount of heat available for combustion are greater; in practice the
relative calorific value is higher (referring to a unit of volume).
For example: the calorific value of the white fir is practically the same as that of the oak, but the oak has a specific
weight that is twice that of the fir. Therefore half the volume of oak must be introduced into the appliance in order to have
the same "heat" obtained from the fir.

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;
-The possibility of creating piping required for the boiling discharge;
-Proximity to the main water drain and/or the boiler (if one already exists);
-Proximity or ease of connection to the water system;
-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 back of the
appliance.
Relocating the appliance should not be done by forcing on the handle, glass or ceramics/steel sides.
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.
Furniture and movable objects must be positioned at least 15 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).
It is recommended to drill the hole in immediate proximity to the appliance.
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.

WOOD BURNING BOILER COOKER ALTEA 110 SICURO TOP

EN - Rev. 1.2
The flue and connection to the same
The flue is an essential element for the efficient operation of the appliance. The boiler cooker smoke outlet is 150 mm in
diameter. The flue must have a minimum cross section of 180 mm with a minimum height of 4 metres. Each product
must be equipped with its own flue, without other adjoining elements (boilers, chimneys, stoves, etc.). The flue
dimensions are closely related to its height, which must be measured from the appliance flue gas outlet to the base of
the stack. In order to guarantee adequate draught, the surface of the chimney flue outlet must be double the flue cross-
section. The discharge pipe for combustion products generated by the forced draught device, must comply with the
following requirements:
-It must seal off the combustion gases, as well as being waterproof and suitably isolated and insulated in relation to
the conditions of use (refer to UNI 9615);
-It must be made of suitable materials capable of withstanding normal mechanical stress, heat, and the effects of
combustion gases and condensate, if any;
-It must go upwards after the vertical section, for the entire remaining part, with a minimum gradient of 20%. The sub-
horizontal section must not have a length greater than ¼ of the effective height H of the flue or chimney, and must
not be longer than 2,000 mm;
-It must preferably have a round internal cross-section: square or rectangular cross-sections must have rounded
corners with radius not inferior to 20 mm;
-It must have a constant, free and independent internal cross section;
-Rectangular cross-sections must have a maximum ratio of 1.5 between the sides;
-If the flue is installed externally, it must be insulated in order to prevent the flue gases from cooling and allowing
condensation to form;
-Parts made from non-combustible materials (it is absolutely prohibited the use of aluminium flue) - capable of
withstanding combustion gases and potential condensation - must be used for mounting the flue gas pipes (for the
section from the appliance to the flue inlet);
-It is forbidden to use fibre cement pipes to connect the appliance to the flue;
-Flue gas conduits must not pass through rooms in which the installation of combustion devices is prohibited;
-The flue gas conduits must be assembled in such a way as to guarantee adequate sealing of flue gases during low
pressure operation of the appliance;
-The installation of horizontal sections is prohibited;
-It is prohibited to use counter sloping elements;
-The flue gas pipe must allow for the recovery of soot or be cleanable, and must have a constant cross-section;
-It is forbidden to allow other air intake conduits and system pipes to transit inside the flue gas pipes, even if they are
over-sized.
Below are examples of pipe connections to the flue:
Chimney
The chimney is a device crowning the flue, used to ease dispersion of combustion products.
It must satisfy the following requirements:
-It must have a usable outlet cross-section no less than double that of the flue onto which it is inserted;
-In must be shaped in such a way as to prevent rainwater or snow from seeping into the flue;
-It must be built in such a way as to ensure the discharge of combustion by-products even in the event of winds from
every direction and inclination.

WOOD BURNING BOILER COOKER ALTEA 110 SICURO TOP
14
EN - Rev. 1.2
The outlet height (where height refers to the top of the flue, regardless of any chimney stacks) must be outside of the so-
called reflux zone, in order to prevent the formation of counter-pressures preventing the free discharge of combustion
by-products into the atmosphere.
It is therefore necessary that the minimum heights - indicated in the following diagrams - are observed:
ELECTRICAL CONNECTION
The electric connection must only be performed by qualified staff, in compliance with all general and local safety
standards.
Check that the power supply voltage and frequency correspond to 230V –50 Hz.
The appliance's safety is ensured when it is properly connected to an efficient earthing system.
In the electric connection to the mains power supply, include a 6 A –Id 30 mA differential trip-switch with suitable
breaking load. The electric connections, including the earth connection, must be made after shutting off the electrical
system.
When completing the system, bear in mind that the cables must be laid in an unmovable manner and far from parts
subject to high temperatures. During the final wiring of the circuit, only use components with a suitable electrical
protection rating. Do not pass electric cables in the immediate vicinity of the flue gas pipe, unless they are insulated with
suitable materials. Connection to the mains power supply should only be carried out after the wires have been connected
to the terminal board.
KLOVER srl declines all responsibility for injury to persons and animals or damage to objects due to failure to
connect the appliance to earth or to comply with IEC specifications.
Electronic control unit
The electric control unit installed on the appliance controls the heating pump, switches the motorised three-way valve
fitted on the water system, switches the heat generator ON and OFF (if installed) and starts any additional pumps.
It is composed of:
-Master switch (used to supply power to the control unit itself);
-Pump adjustable thermostat (used to activate or deactivate the pump on reaching, or not, the temperature we set
on the thermostat itself);
-Valve adjustable thermostat (used to exchange any motorised valve on reaching, or not, the temperature we set on
the thermostat itself. It is normally used for DHW in combination with another heat generator);
-AUX adjustable thermostat (used to control whether or not the heat generator reaches the temperature set on the
thermostat);
-SERV adjustable thermostat (used to activate or deactivate an additional pump on reaching, or not, the
temperature set on the thermostat);

WOOD BURNING BOILER COOKER ALTEA 110 SICURO TOP
15
EN - Rev. 1.2
-Thermometer (indicates the temperature of the water inside the boiler unit);
-Acoustic alarm (activated whenever the boiler water temperature reaches 90-95°C);
-Level switch (indicates that water is not up to level inside the boiler).
Two cables exit the control unit, one of which has no plug. The cable with the plug should be connected to a mains
