WATER CIRCUIT INSTALLATION
PLUMBING
Vyda H and Kira H are provided with a closed expansion
tank.
The built-in expansion tank does NOT ensure proper
protection of the water in the entire system from thermal
expansion.
Therefore, installers should assess whether an
additional expansion tank is needed, depending on the
type of system.
ALL OTHER HYDRAULIC COMPONENTS MAY
BE INSTALLED WITHIN THE BOILER STOVE BY
PURCHASING A KIT FROM EDILKAMIN OR IF
PREPARED BY THE INSTALLER.
Plumbing depends on the type of system.
However, there are some “general rules”:
• The hydraulic system must operate at a pressure
between 1 and 1.5-2 bar at running temperature
(hot) in a closed vessel circuit.
• DO NOT install the boiler stove as a replacement in
a system with an open expansion tank.
• The presence of an accumulator (tank) is
recommended but not mandatory. Its advantage
is that it releases the boiler stove from “sudden”
requests from the system and can be integrated
with other heat sources. It reduces fuel
consumption and increases the efficiency of the
system. Edilkamin recommends an accumulator of
at least 20 l/kW.
• The return temperature of water to the boiler
stove must be higher than 50-55° C to prevent the
formation of condensation.
• An accumulator (tank) is needed to heat low-
temperature radiant panels and must be installed
according to the panel manufacturer's instructions.
• The material used in the circuit must be suitable to
withstand overheating.
• The installer must determine whether or not to use
conditioned products. In Italy, refer to UNI 8065
(Water treatment in heating systems for civil use).
• Direct plumbing to radiators prevents proper
operation, owing to the small diameter of their pipes.
Edilkamin offers four internal kits (optional)
PRESSURE GAUGE
Kits are provided with an electronic reading system
for water pressure. Therefore, there is no analogue
pressure gauge. Edilkamin proposes an analogue
pressure gauge as optional.
VENT
During normal operations the vent
is automatic. During installation, the
technician must check the functionality of
the automatic vent and assess whether a
manual vent needs to be installed.
INSTALLER
check that the swivel nut (G) on
the two output pipes of the boiler
stove are closed
Real size templates are available for technicians.

Protection from heat and safety clearances
The surfaces of the building adjacent to the product
must be protected against overheating.
The insulation to be used will depend on the type of
surface in question.
The appliance must be installed in accordance with
the following safety instructions:
- minimum clearance of 15 cm at the sides and 10 cm
at the back from flammable materials;
- no flammable materials may be kept closer than 80
cm from the front of the appliance.
If the product is installed with a wooden wall or a wall
made of other flammable material, the flue must be
appropriately insulated.
If the product is installed on a flammable and/or
combustible floor, or on a floor incapable of bearing
its load*, we recommend placing a steel or glass plate
under the stove to distribute the load.
Contact the retailer for this type of optional feature.
Positioning the product
The product is designed to operate in all climate
conditions. In special circumstances, such as strong
wind, the safety devices may intervene to switch the
appliance off.
Contact the authorised Edilkamin Technical Assistance
Centre.
NOTE
The smoke outlet diameter does not match the chimney system diameter. The chimney system must
be sized in accordance with the national and local regulations.
In particular (this is not an exhaustive list), refer to the EN 13384, EN 1443, EN 1856, EN 1457
standards and to all local regulations.

This chapter has been drawn up pursuant to European
regulations EN 13384, EN 1443, EN 1856 and EN
1457. The installer must observe both these and any
other local regulations. This manual does not in any
way substitute the applicable regulations.
The product must be connected to a smoke exhaust
system which ensures that the smoke produced by
combustion is expelled in complete safety.
Before positioning the appliance, the installer must
check that the flue is suitable.

SMOKE DUCT, FLUE
The smoke duct
(which connects the combustion
(which connects the combustion
chamber smoke outlet with the flue inlet)
chamber smoke outlet with the flue inlet) and the flue
itself must, among other regulatory requirements,
generally:
• receive the outlet from a single product only
(outlets of more than one product together are
not allowed)*; specific regulations apply in certain
countries, therefore the installer must ensure that
the local regulations have been observed;
• be installed vertically for the most part;
• have no downward sloping sections;
• preferably have a round internal cross-section and
nevertheless with a ratio between the sides below
1.5;
• end at roof level with a proper chimney pot: the
flue may not discharge directly on the wall or into
an enclosed space, even if the space in question
opens onto the sky;
• be made of material rated fire reaction class A1 per
UNI EN 13501 or analogous national regulations;
• be appropriately certified, with a suitable chimney
plate if made of metal;
• maintain the same cross-section throughout: it
may only vary immediately after the outlet, not
along the flue.
THE SMOKE DUCT
THE SMOKE DUCT
In addition to the general requirements for the fume
duct and the flue, the fume duct
:
:
• may not be made of flexible metal material;
• must be insulated if routed through unheated
areas or outside;
• must not be routed through rooms where the
installation of combustion heat generators is
prohibited, or that are subject to potential fire, or
that cannot be inspected;
• must enable the recovery of soot and be open for
inspection;
• generally speaking, must not have more than 3
bends with a 90° maximum angle; the technician
who sizes them must assess the situation;
• generally speaking, if there is a horizontal section,
it can have a maximum/average length of 3 metres,
depending on the draught. Nonetheless, take into
account that long sections favour dirt build-up and
are harder to keep clean; the technician who sizes
the pipes must assess the situation.
Avoid infiltration of condensate water
through the flue. If necessary, mount an
anti-condensate ring – ask your chimney
sweeper for details.
Damage caused by condensate water is
not covered by the warranty.
*
In some nations, installations with multiple
flues are permitted under certain conditions.
Depending on regional regulations,
additional safety systems are necessary in
case of connection to multiple flues. Your
chimney sweeper/technician will be able to
provide further details.

THE FLUE
THE FLUE:
In addition to the general instructions applicable to the
fume duct and the flue, the flue
:
:
• must only be used for discharging fumes;
• must be correctly sized to satisfy the requirements
for flue gas discharging (EN 13384-1, a non-
exhaustive example);
• must preferably be insulated, made of steel and
with a round inner cross-section. If rectangular, the
corners must have a radius of no less than 20 mm,
with a ratio between the inner dimensions <1.5;
• must normally have a minimum height of 1.5
metres;
• must have a constant cross-section;
• must be waterproof and thermally insulated to
ensure proper draught;
• preferably mount a collection chamber for unburnt
residues and any condensate build-up;
• if pre-existing, it must be clean to prevent fire
hazards;
• in general, we recommend embedding the flue
in the existing masonry chimney if its diameter
exceeds 150 mm; the technician who sizes the
pipes must assess the situation.
EMBEDDED SYSTEM
EMBEDDED SYSTEM:
In addition to the general requirements applicable to
the fume duct and the flue, the embedded system
must:
• operate in negative pressure;
• be open to inspection;
• comply with the local regulations.
THE CHIMNEY POT
THE CHIMNEY POT
• must be anti-downdraught;
• must have an internal cross section equivalent to
that of the flue and a fumes outlet at least double
that of the interior of the flue;
• for dual flues (which should be spaced at least 2
m apart) the chimney pot receiving the fumes from
the solid fuel appliance or that from the higher
storey, must be at least 50 cm higher than the
other;
• must extend beyond the back-flow zone (in Italy,
refer to UNI 10683 point 6.5.8.);
• must allow for maintenance of the chimney.
EXTERNAL AIR INTAKE
In general, we suggest two alternative ways for ensuring
a proper flow of indispensable combustion air.
Indirect air intake
Install an air outlet at floor level with an effective surface
area (net of the screen or other protections) of at least
80 cm2(10 cm in diameter).
To prevent draughts, we recommend installing the
intake behind the stove or behind a radiator.
Installing it in front of the appliance will create
unpleasant draughts.
Direct air intake
Install an air intake with an effective size (net of the
mesh or other protective equipment) that is at least
equal to that of the air intake at the back of the product.
Choose the diameter based on the load losses.
Connect the air intake to the appliance's air intake
with a pipe that may also be flexible. Increase the pipe
diameter if the pipe is not smooth: assess any load
loss.
A maximum length of 5 metres is recommended, with
no more than 3 bends depending on the draught of
the flue.
The air may be drawn from an adjacent room only if:
• the flow is taken from permanent and unobstructed
openings communicating with the outdoors;
• the air pressure in the adjacent room is never
lower than that of the outdoor pressure;
• the adjacent room is not a garage, subject to fire
hazard, a bathroom or a bedroom;
• the adjacent room is not a shared room in the
building.
In Italy, the UNI 10683 standard states that ventilation
is sufficient even if a pressure difference between
the outdoors and indoors of no more than 4 Pa
is guaranteed (UNI EN 13384-1 standard, a non-
exhaustive example). The installer who issues the
declaration of conformity is responsible for ensuring
these conditions.
