Every appliance must have a vertical ue pipe operating by natural
draught to discharge the combustion gases outdoors.
The ue must:
- comply with regulations in force in the place of installation of the
appliance;
- be tight to the products of combustion, waterproof, suitably insulated,
made with materials resistant to the corrosion of the gases and to
stress;
- be connected to just one stove, rebox or extraction hood (Fig. 2);
- be properly sized, with constant free internal section, equal to or
greater than the diameter of the ue pipe of the stove and at least 3.5
m in length (Fig. 2);
- be mainly in a vertical position with a deection from the axis of no
more than 45° (Fig. 2);
- be at a suitable distance from combustible or ammable materials,
ensured by an air gap or suitable insulating material;
- be of uniform internal section, preferably round. Square or rectangular
sections must have rounded corners with a radius of at least 20mm
and a maximum ratio between the sides of 1.5 (Fig. 3-4-5);
- the walls must be smooth if possible and without narrowing; bends
must be regular and without discontinuity (Fig. 6).
d It is forbidden to make xed or mobile apertures on the ue
pipe to connect appliances other than the one to which it is
already connected.
d It is forbidden to pass other air ducts or service pipes inside
the ue pipe, however large it is.
a If the ue pipe is an incorrect size or installed other than in
compliance with the above instructions, Gruppo Piazzetta
S.p.A. cannot be held liable for malfunctioning of the product,
damage to property or injury to persons or animals.
We recommend that the ue must have a chamber for collecting solid matter and any condensate located below the connection and which may be
easily inspected by means of an airtight door. (Fig. 1)

The chimney stack is a device tted on the top of the chimney that is designed to
aid dispersion of the products of combustion in the atmosphere.
The chimney stack must comply with the following requirements:
- it must have an internal section and shape the same as the ue (A);
- it must have a useful outlet section (B) of not less than twice that of the ue (A);
- the part of the chimney that emerges from the roof or remains in contact with the
outside (e.g. in the case of a at roof), must be covered with brick or tile elements
and in any case well insulated;
- it must be built in such a way as to prevent the penetration of rain, snow and
foreign matter into the ue and to ensure that in the event of winds from all
directions and angle, discharge of the combustion products is assured (chimney
stack with down-draught cowl).
Recommended distances for correct chimney operation.
To ensure trouble-free operation of the chimney and allow correct dilution of the
products of combustion in the air, the chimney stack must be installed at the
distances given below:
- 6-8 metres from any buildings or other obstacles that are higher than the
chimney stack;
- 50 centimetres higher than any obstacles located at a distance less than 5
metres;
- outside the reux area. The size and shape of this area differ according to the
angle of inclination of the roof and it is therefore necessary to adopt the minimum
heights shown below.
Example: Check the slope of the roof (column α), and the anticipated distance of
the chimney stack from the axis of the ridge (column A), if the distance is greater
than “A” the height of the chimney stack may be read in (column H); if the distance
is less than “A” the chimney stack must rise above the ridge by 0.5 metres.

To ensure trouble-free operation the stove/rebox must have the
necessary air available for combustion and this is provided through the
fresh air intake.
The fresh air intake must:
- have a total free cross section at least equal to the size given in the
paragraph “TECHNICAL DATA”;
- be protected by a grille or suitable guard provided it does not reduce
the minimum recommended section;
- be in a position whereby it cannot be obstructed.
The airow necessary for the re may be obtained in different ways:
- through a fresh air intake direct into the room of installation;
- with ducting through pipes direct to the room of installation, increasing
the recommended minimum free cross section by at least 15%;
- from an adjacent room to the place of installation provided this air
ows freely through permanent apertures communicating with the
outside.
a The adjacent room from which air is taken must not have a low
pressure compared to the exterior due to a counter draught
caused by the presence in that room of another appliance in
use or of a suction device.
The permanent apertures in the adjacent room must comply
with the requirements given above.
d Combustion air must not be taken from adjacent rooms used
as a garage or a combustible materials store or for activities
posing a re hazard.
The appliance should be installed in a location which allows safe and convenient use as well as easy maintenance. If the product being installed
requires an electrical socket, the room must also be provided with an earthed power supply in accordance with current regulations.
The room where the appliance is to be installed must comply with the following requirements:
a They must not be used as a garage, store for combustible material or for activities with a risk of re.
a They must not be in a vacuum in relation to the outside environment due to the effect of contrary draught caused by the presence in
the room where the rebox is installed of another appliance or an extractor device.
a Do not use two stoves, a rebox and a stove, a stove and a wood-red cooking range, etc. in the same environment, since the draught
of one could affect the draught of the other.
•Devices suitable for cooking food with relative hoods without an extractor fan may only be used in kitchens.
•Gas appliances of type C are allowed (refer to current legislation and regulations in the place of installation).

d Gas appliances of type B are not allowed (refer to current legislation and regulations in the place of installation).
d The stove or rebox must not be used simultaneously with collective type ventilation ducts with or without extractor fan, other
devices or other appliances such as: forced ventilation systems or other heating systems using ventilation to change the air. Such
systems could cause a vacuum in the environment of installation even if installed in adjoining or communicating rooms.
d The stove or rebox must not be used: in stairwells except in buildings with no more than two apartments; in corridors for common
use; in bedrooms; in bathrooms or shower-rooms.
Check the load-bearing capacity of the oor by adding together: the weight of the protections (lining walls), insulating materials, surround (given in
the surround instruction booklet) and the stove (given in the paragraph “TECHNICAL DATA”).
If the oor has an unsuitable load-bearing capacity, take adequate countermeasures.
Check the heating capacity of the appliance by comparing the rated power given in the paragraph “TECHNICAL DATA” with the power required by
the environment to be heated.
The energy requirement may be calculated approximately by multiplying the square metres of area by the height of the ceiling; the result is then
multiplied by a coefcient, which depends on the degree of insulation of the building, that is, on internal and external factors of the dwelling:
-Internal factors: type of window and door frames, thickness of the insulation and walls, type of building materials, presence of stairwells, walls
with extensive glazing, high ceilings, position of the rooms to be heated in relation to other adjacent heated or unheated rooms, ….
-External factors: geographical position, average outdoor temperature, exposure, wind speed, latitude, altitude,…
Example of approximate calculation of the energy requirement to heat a xed volume to 18/20° C:
The coefcient that is normally used is determined according to the real conditions as they occur case by case.
•From 0.04 to 0.05 kW per cubic metre in a well insulated environment.
•From 0.05 to 0.06 kW per cubic metre in a poorly insulated environment.
3 rooms measuring 20 m2X (H ceiling) 2.7 m = 162 m3(volume)
In an environment with a good degree of insulation, an average value (coefcient) of 0.045 kW may be taken
162 (volume) X 0.045 (kW) = 7,3 kW necessary (6300 kcal/h)
Conversion 1 kW = 860 kcal/h
a Consult a heating technician or engineer for a correct check and calculation of the requirement of the environments to be heated (see
“REFERENCE STANDARDS”).
a Rated power being equal, products with the Multi-re system can evenly distribute heat throughout the rooms to be heated.

Walls
FLAMMABLE WALLS: the installation of the appliance next to ammable
walls Pis only permitted where suitable insulation and non-combustible
protective material is used.
In order to insulate the appliance and correctly install the cladding,
construct a supporting wall made of non-ammable material (e.g.
plasterboard) placing a thermal insulation layer Lwith thickness of 3
cm between this supporting wall and the ammable wall P.
Always leave a 5 cm air interspace between the appliance and
supporting wall. (Fig. 15)
NON-FLAMMABLE WALLS: always leave a 5 cm air interspace between
the appliance and wall Q. (Fig. 16)
Ceiling
FLAMMABLE CEILING: where there is a ammable ceiling R, create a
false ceiling Susing non-ammable material with at least 8 cm thick
thermal insulation. (Fig. 17)
There must be a minimum distance of 20 cm between false ceiling S
and connection to the ue.
NON-FLAMMABLE CEILING: there must be a minimum distance of 20
cm between the ceiling and connection to the ue. (Fig. 17)
a Reference to minimum ceiling distance denotes the distance
between connection to the ue and any other element located
above (e.g. beams).
Ground or ooring
Where the ground or ooring consists of ammable materials, it must
be protected by a 3 cm thick thermal insulation layer.
Hazardous radiation area
The radiation area refers to the area between the reside opening up to
a distance of 80 cm outwards, both to the front and sides. No ammable
objects must be placed within this area, for example: carpets, curtains,
wood furniture, ornaments, ammable liquids, products to ignite res
or rewood, etc.
a Failure to comply with the above could result in re!!!

Area surrounding the chimney
Where the ooring surrounding the rebox is made of ammable
material, you must protect it using NON-FLAMMABLE materials, or it
must be replaced with ooring made of non-ammable material.
Below, we will demonstrate how to identify this area.
•The ooring in the area in front of the rebox “A”, must be covered
up to a distance equal to the height “H” + 30 cm, essentially at least
50 cm.
•The ooring to the sides of the rebox ”B”, must be covered up to a
distance equal to the height “H” + 20 cm, essentially at least 30 cm.
(measured from the internal edge of the reside opening).
Example: with coverings where H = 38 cm (where reinforced concrete
slabs are not used in the instance of poor transverse ground bearing), A
= 68 cm and B = 58 cm.
a The item “H” refers to the height from the ooring to the re
level. (See gure 17)
B = H+20 cm
Bmin = 30 cm
A = H+30 cm

a The pellet stove is not the same as other stoves. It has a
forced draught of ue gas by a fan, which keeps the rebox
in a vacuum and the entire ueway slightly pressurised. For
this reason the ue must be completely airtight and correctly
installed to ensure both trouble-free operation and user safety.
•The ueway must be made by specialised personnel or rms, as
outlined below.
•The ue must be installed in such a way as to guarantee that periodic
cleaning can be carried out without dismantling any parts whatsoever.
•Pipes should always be sealed with silicone (not cement-based
sealants) or specially adapted gaskets/seals, which retain their
strength and elasticity at high temperatures (250°C), and should be
xed with 3.9 mm Ø self-tapping screws.
a Using the relative pipe clips, x the ue to the wall so that it
does not weigh on the smoke fan.
d Do not install dampers or valves that could block the passage
of ue gas.
d Do not connect to a ueway into which other appliances
(boilers, extractor hoods, etc.) discharge fumes or vapours.

Pipes and maximum usable lengths
Pipes of painted aluminium-clad steel (minimum thickness 1.5mm),
stainless steel (AISI 316) or enamelled steel (minimum thickness 0.5
mm) with a nominal diameter of 80 or 100 mm (for pipes which run
inside the ue maximum diameter 150 mm) can be used.
The male-female connectors must have a minimum length of 50 mm.
The diameter of the pipes depends on the type of installation. The stove
was designed to take 80 mm diameter pipes but, as shown in Table
1, in some cases the use of double-lined 100 mm diameter pipes is
recommended.

EXAMPLE: if installing a section greater than 4.5 m in length with
80 mm diameter pipe, calculate the maximum usable length in the
following ways.
•If a maximum of three 90° bends are used, the maximum length of
the section will be 4.5 m.
•If a maximum of two 90° bends are used and bearing in mind that a
90° bend can be replaced by one metre of pipe, the maximum length
of the section will be 4.5 m + 1 m = 5.5 m.
•If a maximum of one 90° bend is used and bearing in mind that a 90°
bend can be replaced by one metre of pipe, the maximum length of
the section will be 4.5 m + 1 m + 1 m = 6.5 m.
Where 100 mm diameter pipe must be used, connect it to the stove ue
outlet with a 80 mm union-tee then use a 80 mm 100 mm adaptor (not
supplied by Piazzetta) (Fig. 19).
Union-tee
The use of this type of tting must allow for the collection of condensate
mixed with soot, which builds up inside the pipe. It must also permit
periodic cleaning of the ue without the need to disassemble the pipes.
This type of tting can be bought at Piazzetta retail outlets together with
the pipes.
An example is given below of a ueway connection, which allows
complete cleaning without having to disassemble the pipes (Fig. 20).

If you wish to use an existing chimney it is strongly recommended that
you have it checked by a professional chimneysweep to ensure that it
is completely airtight. The reason for this is that the smoke, because it
is slightly pressurised, can inltrate any cracks in the ue and escape
into living spaces. If upon inspection you nd that the chimney is not
completely sound, it is recommended that you insert piping made of
new material. If the existing chimney is wide enough we recommend a
pipe with a maximum diameter of 150mm. It is also recommended that
you insulate the chimney ue (Fig. 21-22).
Pipes and bends made by Gruppo Piazzetta S.p.A. are recommended
for connection to the ueway, since they are sized to t the ue outlet
of the appliance.
Other pipes may be applied after adaptation and checking of the
compatibility of the coupling, taking into account that the pipes and
bends must be made in compliance with current regulations. In this
case, however, Gruppo Piazzetta S.p.A. only guarantees trouble-free
operation for parts that it manufactures and that are used according to
specications.
•If the connector has to pass through partitions or walls of inammable
or heat-sensitive materials, or through load-bearing walls, create an
insulating barrier equal to or greater than 10cm around the connector
using mineral-based insulating material (rock wool, ceramic bre)
with a nominal density greater than 80 kg/m3.
•If the connector has to pass through non-ammable partitions
or walls, create an insulating barrier equal to or greater than 5cm
around the connector using mineral-based insulating material (rock
wool, ceramic bre) with a nominal density greater than 80 kg/m3.
•Check that the connection to the ueway is gas/smoke-tight, since
the appliance operates in a vacuum.
•Check that the pipe does not penetrate too far into the ueway,thereby
choking the pipe for the passage of smoke and combustion gases.
a Ensure that all installation work is carried out to professional
standards.

An external ue can be used provided it complies with the following
requirements:
- use only insulated stainless steel pipes (double-lined) xed to the
outside wall of the building (Fig. 23);
- there must be an inspection opening at the base of the ue to permit
periodic checks and maintenance;
- the ue must be tted at the top with a chimney stack with down-
draught cowl, also ensuring compliance with the safety distance from
the roof ridge as outlined in the section entitled “CHIMNEY STACK”.
a Ensure that all installation work is carried out to professional

1.12 USING AN ExTERNAL FLUE
The hood grille has the function of allowing air to pass from inside the
hood to the environment or vice versa if the Multifuoco system is installed.
Warm air comes out of the hood grille with the natural convection system
and it is therefore necessary to maintain the safety distances from
ammable materials such as: ammable ceilings or walls, ledges/beams,
furniture, curtains, etc.. The hood grille must be installed at least 50 cm
from the ceiling and with at least 30 cm safety distance to the sides.
For the hood grille size, see the “TECHNICAL DATA” paragraph.
a Two non-closable hood grilles must be installed without
connecting them to the stove so that the warm air that has
stratied inside the lining wall can ow out.
a With a ceiling over 3 metres high, two NON-CLOSABLE hood
grilles must be installed on the hood lining at a height of 30 cm
from the ceiling to allow the stratied air to ow out.
Wooden nishes, e.g. Wood mantels, may be mounted on the surround.
Wood mantels MUST be:
- installed outside the heat radiation area;
- self-supporting;
- installed with 1cm air gap from the surround or from the heating part.
a The expansion joint is in ceramic bre, which has the function
of insulating the surround from the metal structure of the stove.

The wood pellet is obtained by pressing wood sawdust left over from
the working of natural dried wood. The typical small, cylindrical form is
obtained by passing the material through a die.Thanks to lignin, a natural
element which is released during the pressing of the raw material, the
pellets acquire a good consistency and compactness without requiring
treatment with additives or caking agents.
There are various types of pellet on the market with qualities and
characteristics that vary depending on the processes they have
undergone and the type of wood used in their production.
Since the characteristics and quality of the pellet considerably
affect stove performance, efciency and proper operation, we
recommend that you use high-quality pellets.
Gruppo Piazzetta S.p.A has tested and programmed its stoves and
can ensure best performance and trouble-free operation using
pellets with the following specic characteristics:
Pellet characteristics
Components natural pure wood pellet
Length, approx. 10 – 30 mm
Diameter, approx. 6 – 6.5 mm
Apparent density, approx. 650 kg/m3
Specic weight, approx. > 1.0 kg/dm3
Net heat value, approx. 5 kWh/kg
Moisture content, approx. <8%
Residual ash, approx. <0.5%
N.B.: the above data refer to beech/r wood pellets
To ensure trouble-free operation:
DO NOT use pellets with dimensions other than those recommended by
the manufacturer.
DO NOT use poor quality pellets containing sawdust, bark, maize, resins
or chemical substances, additives or adhesives.
DO NOT use damp pellets.
Choosing other and unsuitable pellets
- obstructs the grate and ue gas pipes;
- increases fuel consumption;
- reduces efciency;
- means that proper stove operation cannot be guaranteed;
- causes dirt to build up on the glass;
- leaves particles which have failed to burn and heavy cinders.
The presence of moisture in the pellets increases their volume and
causes them to split which in turn causes:
- malfunction of the fuel-loading system;
- inefcient combustion.
Pellets should be stored in a sheltered, dry place.
To use good quality pellets with dimensions and heat-producing
properties other than those recommended above, it will be necessary to
change the stove operating parameters.
a This “customisation” of stove settings must be carried out
at a Gruppo Piazzetta S.p.A. Service Centre or by specially
qualied personnel authorised by Gruppo Piazzetta S.p.A.
a Using pellets that are out of date or not in conformity with
the manufacturer’s recommendations not only damages the
stove and jeopardises its performance, but can render the
guarantee null and void and relieves the manufacturer of all
liability.
