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 corrosion by the gases and to stress;

- be connected to just one stove, 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 stove 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;

- 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).

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

The chimney stack is a device fitted 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 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.

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;

- 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 flows

freely through permanent apertures communicating with the outside.

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.

1.5 INSTALLATION ENVIRONMENT

DT2010033-01

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:

they must not be used as a garage, store for combustible material or for activities with a risk of fire.

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 fi replace is installed of another appliance or an extractor device.

Do not use two stoves, a fireplace and a stove, a stove 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 stove or 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 stove or 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.

Check the load-bearing capacity of the floor, referring to the weight of the product given in the paragraph “TECHNICAL DATA”.

If the floor does not have a suitable load-bearing capacity, adequate countermeasures must be taken, for example, by using a sheet metal plate to

distribute the load.

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 20m2 X (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”).

Install the product in compliance with the recommended safety
distances from heat sensitive or inflammable materials, from load
bearing and other walls and also from wooden elements, furniture, etc.
In the case of flooring that is heat sensitive or inflammable the floor must
be protected with non-combustible insulating material, e.g. sheets of
steel plate, marble, tiles, etc.
The minimum distances are:

Connection to the flue must respect the 40 cm minimum safety
distance from heat-sensitive structural components or inflammable
materials (wood panelling, beams or ceilings, etc).

Keep any combustible product such as wooden furniture,
curtains, carpets, combustible liquids, etc. well away from
the stove when it is lit (minimum distance 80 cm).

It is advisable to leave more than the recommended 20 cm
gap at the side of the stove to facilitate any maintenance on
the appliance.

The pellet stove is not the same as other stoves. It has a forced
draught of flue gas by a fan, which keeps the firebox in a vacuum
and the entire flueway slightly pressurised. For this reason the
flue must be completely airtight and correctly installed to ensure
both trouble-free operation and user safety.

- The flueway must be made by specialised personnel or firms, as outlined

below.

- The flue 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 fixed with 3.9 mm
ø self-tapping screws.

Do not install dampers or valves that could block the passage of
flue gas.

Do not connect to a flueway 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 0.5mm) with a nominal diameter of 80 or 100 mm (for
pipes which run inside the flue 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.

Losses in pressure associated with a 90° bend can be
compared to those incurred by one metre of pipe. An
inspectable union-tee can be considered equivalent to a 90°
bend.

EXAMPLE: : if installing a section greater than 4.5m in length with
80mm 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 4.5m

- 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 4.5m+1m=5.5m

- 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 4.5m+1m+1m=6.5m

Where 100mm diameter pipe must be used, connect it to the stove
flue outlet with a 80mm union-tee then use a 80mm 100mm adaptor
(not supplied by Superior) (Fig. 19).

Union-tee

The use of this type of fitting must allow for the collection of
condensate mixed with soot, which builds up inside the pipe. It must
also permit periodic cleaning of the flue without the need to
disassemble the pipes.
This type of fitting can be bought at Superior retail outlets together
with the pipes.
An example is given below of a flueway 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 infiltrate any cracks in the flue and escape
into living spaces. If upon inspection you find 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 flue (Fig. 21-22).

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.
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.

Connection to the flue must respect the 40cm minimum safety
distance from heat-sensitive structural components or inflammable
materials (wood panelling, beams or ceilings, etc). (See figures 17-18).

- If the connector has to pass through partitions or walls of inflammable
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 fibre) with a nominal density greater than 80kg/m3.

- If the connector has to pass through non-flammable partitions or
walls, create:
an insulating barrier equal to or greater than 5cm around the
connector using mineral-based insulating material (rock wool,
ceramic fibre) with a nominal density greater than 80kg/m3.

- 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.

Ensure that all installation work is carried out to professional
standards.

An external flue can be used provided it complies with the following
requirements:

- use only insulated stainless steel pipes (double-lined) fixed to the
outside wall of the building (Fig. 23);
