CS.VTR.IST-1 / Rev 1.1 ENGLISH
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 %.
-100% wood. Totally additive-free.
-Maximum ash residue 1.1 %.
To obtain good performance 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.
Good quality pellets should have the following properties:
-Constant diameter cylinders with a smooth, shiny surface;
-There should not be a lot of sawdust inside the packaging;
-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 be compliant with some international standards (such as EN14961-2, DIN 51731 and O-NORM M7135) which establish
minimum values for quality checks on pellets. To facilitate the right choice of the combustible material you can find below one of the most common
certification marks identifying the quality of the pellets:
The use of poor quality pellets or any other material can damage the appliance 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.

CS.VTR.IST-1 / Rev 1.1 ENGLISH
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 50 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.

CS.VTR.IST-1 / Rev 1.1 ENGLISH
The flue and connection to the same
The flue is an essential element for the efficient operation of the appliance. The flue must have a minimum cross-sectional area as that indicated in the
technical specifications of the appliance (80 mm). 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 5%. 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.
FURTHER SPECIFICATIONS TO BE CONSIDERED
-The appliance works with the combustion chamber in depression and the flue pipe in pressure; it is essential that the flue gas outlet is hermetically
sealed.
-The flue pipes inside the installation room must be made of a suitable material (see current regulations) and equipped with seal gaskets with a minimum
diameter of 80 mm.
-The pipes must have a double wall (thermally insulated) or be suitably insulated with rock wool. The maximum temperature of the flue pipe inside the
room must not exceed 70°C.
-IT IS MANDATORY TO HAVE AN INITIAL VERTICAL SECTION OF AT LEAST 1.5 MT IN ORDER TO GUARANTEE CORRECT FLUE GAS
DISCHARGE.
-Every direction change must be carried out with a T-shaped fitting and inspection cap. The tubes must be air tight through special seals which resist
up to 250° C. Attach the pipes to the wall with special collars to avoid any vibration.
-IT IS STRICTLY FORBIDDEN TO INSTALL DRAUGHT REGULATION VALVES (BUTTERFLY VALVES).

9
CS.VTR.IST-1 / Rev 1.1 ENGLISH
If the flue should be old or too big (internal diameter greater than 15 cm), duct the flue using a stainless steel pipe, properly insulated with rock wool or
vermiculite, and sized according to the route. The connection to the flue must be appropriately sealed.
When assembling the flue, there must be no more than 4 direction changes, including the initial T-shaped fitting.
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.
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:

10
CS.VTR.IST-1 / Rev 1.1 ENGLISH
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 220V –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.
NORDIC FIRE 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.
