INSTALLATION

GENERAL

The ue gas exhaust and hydraulic connections must be carried out by qualied personnel who must issue installation conformity
documentation compliant with national standards.

The installer must provide the owner or person acting for him, according to the legislation in force, with the declaration of conformity,
supplied with:

1) the use and maintenance manual of the appliance and of the system components (such as for example, the smoke ducts, chimney, etc.);

2) photocopy or photograph of the chimney plaque;

3) system booklet (where applicable).

The installer must ask to be issued with a receipt stating that the documentation has been provided, and must keep it with a copy of the technical
documentation relating to the installation.

For installation in a condominium, prior approval from the condominium's administrator must be requested.
Where required, check the exhaust gas emissions after installation. Should a sampling point be installed, it must be airtight.

COMPATIBILITY

Do not install in rooms with a re hazard. It is also forbidden to install it in living areas with the following characteristics:

1. where there are liquid fuel appliances with continuous or discontinuous operation that draw the combustion air into the room in which they
are installed.

2. where there are type B gas appliances intended for heating, with or without domestic hot water production and in adjacent and communicating
rooms.

3. where the depression measured in situ between the external and internal environment is greater than 4 Pa.

N.B.: Watertight appliances can also be installed in the cases indicated in points 1, 2 and 3 of this paragraph.

INSTALLATIONS IN BATHROOMS, BEDROOMS AND STUDIO FLATS

Installation in bathrooms, bedrooms and studio ats is only allowed for sealed or closed hearth appliances with ducted combustion air taken
from the outside.

oor protection

POSITIONING AND SAFETY DISTANCES

The support surfaces and/or points must have a suitable capacity to bear the overall weight
of the appliance, accessories and coverings. If the oor is made of a combustible material,
we recommend using a non-combustible material to protect the front part from any burnt
material which might fall during routine cleaning operations. The generator must be level
to function properly. The side walls, the rear walls and the oor support surface should be
made of non-combustible material.

One must also bear in mind all laws and national,
regional, provincial and town council regulations in force
in the country in which the appliance has been installed,
as well as the instructions contained in this manual.

Air inlet

Under any condition, including in the presence of extractor hoods and/or of controlled forced ventilation systems, the pressure dierence
between the generator installation rooms and the outside must always be equal to or less than 4 Pa.

MINIMUM DISTANCES

Installation next to ammable or heat-sensitive materials is permitted only if the special
safety distances specied on the label at the beginning of the manual (pag.2) are
observed. If the materials are not ammable, you must keep a side and rear distance of at

least 100 mm (without the inserts). For products equipped with rear spacers, wall-mounting
installation is permitted exclusively for the rear side.

PREPARATIONS FOR MAINTENANCE

To carry out extraordinary maintenance operations on the product, it may be necessary to move it away from the adjacent walls. This must be
done by a technician authorised to disconnect the combustion product evacuation ducts and then reconnect them. For heaters connected to the
hydraulic system, the connection between the system itself and the product must be made in such a way that, when an authorised technician is
about to carry out extraordinary maintenance operations, it is possible to move the heater at least 1 metre away from the adjacent walls.

EXAMPLES OF CORRECT CONNECTION TO THE CHIMNEY

In the presence of type B gas appliances with intermittent operation not intended for heating, they must have their own aeration and/or
ventilation opening.

The air inlets must meet the following requirements:

 they must be protected with grids, metal mesh, etc., but without reducing the net useful section;
 they must be made so as to make the maintenance operations possible;
 positioned so that they cannot be obstructed;
The clean and non-contaminated air ow can also be obtained from a room adjacent to that of installation (indirect aeration and
ventilation), as long as the ow takes place freely through permanent openings communicating with the outside.
The adjacent room cannot be used as a garage, or to store combustible material or for any other activity with a re hazard, bathroom,
bedroom or common room of the building.

FLUE GAS EXHAUST

The heat generator works in depression and is equipped with an outlet fan for ue gas extraction. There must be a single exhaust system for
the generator. Using a ue that is shared with other devices is not allowed.

The components of the ue gas exhaust system must be chosen in relation to the type of appliance to be installed in compliance with:

 UNI/ TS 11278 in the event of metal chimneys, with particular attention to that stated in the specication;
 UNI EN 13063-1 and UNI EN 13063-2, UNI EN 1457, UNI EN 1806 in the event of non-metallic chimneys.
 The length of the horizontal section must be minimal and, in any case, no longer than 3 metres, with a minimum upward slope of 3%
 There must not be more than 4 direction changes including the one due to the use of the "T" element.
 A “T” tting with a condensation collection cap must be provided at the base of the vertical section.
 If the exhaust is not inserted in an existing ue, a vertical section with a windproof end piece is required (UNI 10683).
 The vertical duct can be inside or outside the building. If the smoke duct is inserted in an existing ue, it must be certied for solid fuel.
 If the smoke duct is outside the building, it must always be insulated.
 The smoke ducts must have at least one airtight inlet for ue gas sampling.
 All the sections of the ue gas duct must be accessible to inspection.
 Inspection openings must be provided for cleaning.
 If the generator has a fume temperature lower than 160°C+ ambient temperature caused by the high yield (contact technicians) it

MUST be resistant to humidity.

 A ue system that does not respect the previous points or, in general, that does not comply with the regulations, may cause condensation

phenomena inside it.

CHIMNEY CAP

The chimney caps must meet the following requirements:

 they must have a useful outlet section no less than double that of the chimney/ducted system on which it is installed;
 they must be adapted in order to prevent the penetration of rain and snow in the chimney/ducted system;
 they must be built so that, in the event of winds coming from all directions and from any angle, the expulsion of combustion products

is in any case ensured;

Hermetically sealed installation

The generator is a fully sealed product with respect to the environment in which it is installed. This means that it is ideal for passive houses
because it does not take air in from within the house.

combustion air

To ensure the stove remains hermetically sealed, the connection pipe for the combustion air must be directly connected to the exterior, using
special pipes and sealed connectors.

Fumes exHaust system

• If the generator has a fumes temperature of less than 160°C+ room temperature due to the high performance (refer to technical data),
the fumes exhaust system must be completely waterproof.

• If there is a possibility that fumes may condense, an external inspection hatch must be tted.

INSTALLATION AND SAFETY DEVICES

The installation, relative system connections, commissioning and inspection of correct functioning must be carried out perfectly, in full
compliance with Standards in force, national, regional and municipal, as well as these instructions. For Italy, installation must be carried out by
professionally qualied sta (Ministerial Decree dated 22.01.08 n°37).

Extraame S.p.A. declines all responsibility for damage to objects and/or persons caused by the system.

TYPE OF SYSTEM

 There are 2 dierent types of system:
 Open vessel system and closed vessel system.
 The product has been designed and made to work with closed vessel systems.

CHECK THAT THE PRELOAD OF THE EXPANSION VESSEL IS SET TO 1.5 BAR.

SAFETY DEVICES FOR CLOSED VESSEL SYSTEM

In accordance with the UNI 10412-2 (2009) regulation in force in Italy, all the closed systems must be tted with: safety valve, pump control
thermostat, temperature indicator, pressure indicator, automatic circuit breaker block switch (block thermostat), circulation system,
expansion system, and safety dissipation built-in to the generator with thermal safety valve (self-activated), if the appliance does not have a
temperature self-adjustment system.

Pay attention to the correct sizing of the system:

 generator power compared to the thermal requirement
 possible need for a buer tank

13

ENGLISH

DISTANCES OF SAFETY DEVICES ACCORDING TO THE STANDARD

The temperature safety sensors must be in place on the machine at a distance no greater than 30 cm from the ow connection. Whenever the
generators lack a device, those missing can be installed on the generator ow pipe, within a distance no greater than 1 m from the machine.

COMMISSIONING CHECKS

Before connecting the boiler:
a) wash all system piping thoroughly in order to remove any residues which might compromise the correct functioning of certain system
components (pumps, valves, etc.).
b) The company recommends installing a magnetic lter in the generator return, to increase the operational life of the boiler, make it easier
to remove impurities and increase the overall eciency of the system.
It is also advisable to perform an inspection using appropriate instruments, to check for any stray currents that may cause corrosion.
c) check to verify that the ue has adequate draught, that it is not narrowed and that other appliances do not discharge into the ue. This is to
prevent unexpected power increases. The ue tting can be mounted between the boiler and the ue only after this inspection. An inspection
of the connections with pre-existing ues is recommended.

ANTICONDENSATION DEVICE MANDATORY

Make sure a suitable anti-condensate circuit has been realised, which guarantees an appliance return temperature of at least 55°C. The
automatic thermostatic valve, for instance, is used in solid fuel boilers as it prevents cold water from returning into the exchanger. A high
return temperature allows eciency improvement, reduces formation of smoke condensation and prolongs the generator’s life span. The
manufacturer recommends using the 55°C model with 1” hydraulic connections.

For the products with the *PWM pump control thermostat, installation is considered equivalent to the realisation of a suitable anti-condensate
circuit in the case where::

- the heat generator pump is the only one in the installation, or

- there is a plate heat exchanger between the heat generator and the installation, or

- there is a hydraulic compensator or an inertial storage tank (buer) between the heat generator and the installation
