English
Every appliance must have a vertical flue pipe operating by natural draught to
discharge the combustion gases outdoors.
The flue 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 fireplace, fireplace or extraction hood (Fig.2);
- be properly sized, with constant free internal section, equal to or greater
than the diameter of the flue pipe of the fireplace and at least 3.5 m in length
(Fig.2);
- be mainly in a vertical position with a deflection from the axis of no more
than 45° (Fig. 2);
- be at a suitable distance from combustible or flammable materials, ensured
by an air gap or suitable insulating material (Fig.3);
- be of uniform internal section, preferably round. Square or rectangular
sections must have rounded corners with a radius of at least 20 mm 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).
It is forbidden to make fixed or mobile apertures on the flue
pipe to connect appliances other than the one to which it is
already connected.
It is forbidden to pass other air ducts or service pipes inside
the flue pipe, however large it is.
If the flue 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 flue 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.

1.3 CHIMNEY STACK - Fig. 7 / 11
The chimney stack must comply with the following requirements:
- it must have an internal section and shape the same as the flue (A);
- it must have a useful outlet section (B) of not less than twice that of the
flue (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 flat 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 flue 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 reflux 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.

1.4 FRESH AIR INTAKE - Fig.12 / 14
To ensure trouble-free operation the stove/fireplace 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 airflow necessary for the fire may be obtained in different ways:
- through a fresh air intake direct into the room of installation (we
kindly advise you to place the air intake behind the firebox so that the
air warms up before circulating in the room); (Fig. 12)
- with ducting through pipes direct to the room of installation,
increasing the recommended minimum free cross section by at least
15%; (Fig. 13)
- from an adjacent room to the place of installation provided this air
flows freely through permanent apertures communicating with the
outside. (Fig. 14)
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.
Combustion air must not be taken from adjacent rooms
used as a garage or a combustible materials store or for
activities posing a fire hazard.

Check the load-bearing capacity of the floor by adding together: the weight of the protections (lining walls), insulating materials, surround (given in the
surround instruction booklet) and the fireplace (given in the paragraph “TECHNICAL DATA”).
If the floor 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 coefficient, which depends on the degree of insulation of the building, that is, on internal and external factors of the dwelling:
a) 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, …
b) External factors: geographical position, average outdoor temperature, exposure, wind speed, latitude, altitude, …
Example of approximate calculation of the energy requirement to heat a fixed volume to 18/20° C:
The coefficient 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 20m2X (H ceiling) 2.7m = 162 m3(volume)
In an environment with a good degree of insulation, an average value (coefficient) of 0.045 kW may be taken
162 (volume) X 0.045 (kW) = 7.3 kW necessary (6300 kcal/h)
Conversion 1kW = 860 kcal/h
Consult a heating technician or engineer for a correct check and calculation of the requirement of the environments to be
heated (see “REFERENCE STANDARDS”).
Rated power being equal, products with the Multifuoco System®can evenly distribute heat throughout the rooms to be heated.

1.7 HEATING CAPACITY
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.
It can not be used as a garage, store for combustible material or for activities with a risk of fire.
It can 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 fireplace is installed of another appliance or an extractor device.
Do not use two stoves, a fireplace and a stove, a fireplace and a wood-fired 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)
Gas appliances of type B are not allowed (refer to current legislation and regulations in the place of installation).
The fireplace 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.
The fireplace 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.

Diffusion with the Multifuoco System - Fig.15 - 16
An original Piazzetta system designed to distribute heat evenly throughout
the environment, even for several rooms on different floors.
The Multifuoco System®is very simple to install. It is necessary to install the
ventilation kit, following the instructions given with the same, before positio-
ning the fireplace and installing the surround.
After having installed the ventilation kit, it is necessary to connect the warm
air outlets to the fan using 75 mm diameter hoses.
The warm air outflow may be sent in a maximum of four directions using
two “Y-elements”. It is advisable to install closable warm air outlets and only
one of these may be installed at a distance of less than six metres from the
fireplace, keeping the remaining outlets closed so that distribution may be
adjusted as required.
With the Multifuoco System®the KNOCKOUTS on the rear of the fireplace
must NOT BE REMOVED, otherwise the apertures must be covered over with
a metal plate sealed with silicone resistant to high temperatures and fixed
with self-drilling screws. (Figure 18)
Under no circumstances must collars and any knockouts on the upper part of
the fireplace (see figure 16) be obstructed in order to allow proper operation
of the Multifuoco System®and the regular outflow of the warm air that stra-
tifies inside the internal hood and comes out the hood grilles.
It is compulsory to install a hood grille also with the Multifuoco
System. For the size of the hood grille, see the “TECHNICAL
DATA” paragraph.
The warm air ducts must be made of non-flammable, resilient
and if possible smooth material. To decrease heat loss the
pipes must be suitably lagged with insulating material.
Diffusion by natural convection - Fig.17 - 18
For the stove to work by natural convection the 5 knockouts in the lower part
of the rear panel must be opened during installation.
The 3 upper knockouts are opened according to requirements.
All 3 knockouts may be opened letting the air flow naturally through the
hood grill or (recommended procedure) one or two may be opened, installing
specific collars for ME stoves, to duct warm air to the optional grilles located
in the top part of the surround or in the walls of adjacent rooms.
There must be apertures or grilles located underneath the grate (Fig. 17) that
cannot be closed and they must have a minimum useful section as indicated
in the “TECHNICAL DATA” paragraph.

FLAMMABLE WALLS: the fireplace may be installed near flammable walls
provided suitable protection consisting of insulating and non-combustible
material is inserted.
To insulate the fireplace and to install the surround correctly, construct a
lining wall in non-flammable material (e.g. plasterboard) and insert a 8 cm
thick layer of insulating material between the two walls.
Always leave a gap of 10 cm between the fireplace and the lining wall. (Fig. 20)
NON-FLAMMABLE WALLS: always leave a gap of 5 cm between the
fireplace and the lining wall. (Fig. 21)
Minimumdistancefromtheceilingmeansthedistancebetween
connection to the flueway and any elements located above it
(e.g. beams).
FLAMMABLE CEILING: insulate the top part of the fireplace with 10 cm of
insulating material and create a false ceiling of non-flammable material with
at least 8 cm of insulating material. (Fig. 22)
The minimum distance between the false ceiling and connection to the flueway
must be 20 cm, while the flue connection must be insulated with at least 3
cm thick non-flammable material that is resistant to high temperatures.
If the surround canopy and the flue connection are metal, the minimum
distance from the false ceiling may be reduced to 10 cm, but the insulation
of the connection to the flueway must be at least 6 cm thick.
NON-FLAMMABLE CEILING: the minimum distance between the ceiling
and connection to the flueway must be 20 cm. (Fig. 22)
If the floor is made of flammable material, it must be protected with a 4 cm
layer of insulating material. (Fig. 22)
Always leave a 10 cm air space between the fireplace and the floor.
The heat radiation area is considered as being from the hearth opening
up to 1 metre away both to the front and the side. No flammable element
must be placed within this area, such as: carpets, curtains, wood furniture,
ornaments, flammable liquids, fire-lighting products or firewood, etc.
Failure to comply with the above could cause a fire!!!

If the floor around the fireplace is made of flammable material, it must be
protected with non-flammable material or be replaced with a floor of non-
flammable material.
This area may be recognised as follows. (Fig. 23)
Towards the front part of the fireplace “A”, the floor must be covered for a
distance equal to the height “H” + 30 cm and in any case not less than 50 cm.
Towards the side of the fireplace ”B”, the floor must be covered for a distance
equal to the height “H” + 20 cm and in any case not less than 30 cm
(measured from the internal corner of the fireplace opening).
Example: for surrounds with H = 38 cm, the result is A = 68 cm and
B = 58 cm.
“H” means the height from the floor to the grate. (Fig. 22)
B = H+20 cm
Bmin = 30 cm
Fig. 23
Fig. 24
Fig. 25
Connection to the flueway must be done using pipes as short as possible
without narrowing or restrictions and with a maximum slope of 45°.
Pipes and bends made by Gruppo Piazzetta S.p.A. are recommended for
connection to the flueway, since they are sized to fit the flue outlet of the
appliance and are also in compliance with regulations and standards.
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 specifications.
WARNINGS WITH REGARD TO FLAMMABLE WALLS OR CEILING:
If the connection has to go through elements or walls in heat-sensitive
flammable materials, create a layer of at least 20 cm insulation around the
connection. (Fig. 24)
After having drilled a hole in the wall to pass the pipe through into the flueway,
the air gaps must be filled with non-flammable, resilient materials with a
reduced capacity of heat transmission (e.g. light concrete); Fig. 25.
Check that the connection to the flueway is gas/smoke-tight, since the
appliance operates in a vacuum.
Check that the pipe does not penetrate too far into the flueway, thereby
choking the pipe for the passage of smoke and combustion gases.
Flexible metal or asbestos-cement pipes must not be used.

The surround or the lining wall of the fireplace must be self-supporting regardless of the materials with which it is made and under no circumstances must
it come into contact with the fireplace. Furthermore, the surround must be made with non-flammable materials in compliance with regulations.
For Gruppo Piazzetta S.p.A. surrounds, follow the instructions enclosed with the product.
Testing and lighting for first time.
Fig. 26
Only a visual inspection can be made in the intermediate stage for fireplace, fireplaces and appliances that must be assembled or clad with brickwork or
require the use of cement binders. In this case operation of the whole installation must be tested after all the building works directly connected with the
“First time of lighting” test have been completed, following the instructions given in the booklet.
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 flammable
materials such as: flammable 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.

3.0 PREPARATION FOR INSTALLING
Carefully read all the information contained in the section “GENERALRULES”
before installing the fireplace.
- Unpack the fireplace.
- Take the accessories out of the hearth and remove the elements that secured
the fireplace during transportation.
- Complete assembly of the grate with the Aluker elements, the ash drawer and
the grids contained in the accessories pack. Proceed as follows:
• position the Aluker parts. First insert the lateral elements, tilting them slightly
forwards. Rest them on the grate support and push them both outwards;
• place the central elements between the two lateral elements that have just been
inserted and push them towards the front and the rear of the fireplace;
• lastly, insert the ash drawer and the grids. (Fig. 30)
- Release the counterweight and the rise n’fall door by removing the locking
screws and bushings from the two sides. (Fig. 31-32)
- Position the fireplace and use suitable shims to make sure it is level, adjusting
the height from the ground according to the chosen cladding or surround.
- Connect the fireplace to the flueway (see paragraph “CONNECTION TO THE
FLUEWAY”).
- Light for the first time and check correct operation (see paragraph
“LIGHTING FOR THE FIRST TIME”).
- If everything is in proper working order, proceed with constructing the lining wall
and assembling the surround.

4.0 USE
Certain basic facts can be all-important for best performance and getting the most out of your appliance. Please find below some basic information intended
to be of use with regard to the choice of firewood, the adjustment of the dampers and proper operation of the appliance.
During operation, some parts of the appliance (door, handle, dampers, surround) can reach high temperatures. Therefore exercise great care and take all
necessary precautions.
When you need to add wood to the fireplace or to adjust the air flow, use the glove or the hand protector provided.
If the door of the product fails to close automatically, operation with the fireplace open will only be possible with constant checking of the flame.
DT2011360-00
DT2010055-03
Use well-seasoned and dry wood with less than 20% moisture content.
Wood that is ready to burn must have been dried in the open air sheltered from rain or snow for at least 2 years after having been cut.
The lower the moisture content of the wood the higher its heating power. Freshly cut wood has 50% less heat value than dry wood.
Burning wood that is too wet means wasting most of the calories for evaporation of the water contained in it and, in particular, the walls of the combustion
chamber and the flue become fouled and encrusted thereby affecting efficiency.
The table below shows how the heating power decreases as the moisture content increases.

Heating power of the wood (beech)*
* Approximate value
It is a good rule to purchase timber during the summer (June-July), since woods are cut down mostly in the autumn and you can therefore be sure that the
timber has already been seasoned for approximately 1 year.
Firewood can be classified in two qualities: “good” and “mediocre or poor”.
This classification is according to the heat yield of the wood, the longest flame time it provides, its composition and density.
Mediocre or poor fuels
Timber that is not recommended comes from the family of conifers,willow,
poplar and alder. These light soft woods are resinous and therefore create
more soot, few embers and incandescent sparks, while requiring more
frequent cleaning of the flue and the fireplace.
Another characteristic of softwood is that it gives a lively but short-
lived flame and the consumption is higher for the same heat output.
Unsuitable fuels
Never use wet wood, tarred wood or pellets.
It is also best not to use: refuse (rubbish), waste paper; paper briquettes;
plywood or chipboard; fibreboard; packaging materials; painted wood or
wood coated with synthetic material, plastic laminates, cardboard or milk
cartons.

Good fuels.
Recommended timber comes from the family of broadleaf hardwoods: beech, hornbeam, oak, false acacia, ash, birch, maple, elm.
All low-resin and close-grained woods (that is hard and heavy timber) are most suitable, since they provide the fireplace with a steady, continuous flame.
