7 Installation
Notice for the installer
The installation of the stove must be carried out by qualified technicians who have to install the
stove in accordance with the European laws and the laws in force in the place, Region or State.
The stove must be electrically powered by a system in accordance with the regulation 72/23 and
93/68 CEE on the power grid.
The stove must be sized according to the environment in which it is installed.
The stove must be positioned vertically.
The stove mustn’t be installed in bedrooms, bathrooms or where there is another heating system
without a self-sufficient air flow (chimney, etc.).
Environment and distances
It is essential to check the environment where the stove will operate for an optimal working.
- The volume of the house or the working environment mustn’t be smaller than 30m³.
- There must be a permanent air opening outwards in the installation room, at least 800cm²,
non-obstructed and protected by a permanent grill.
- The air can be taken by the rooms
contiguous to the room where the stove
has been installed on condition that
there are air intakes, not located in the
bedroom, bathroom or where there are
inflammable materials.
- If the stove is installed in a room with wooden or inflammable floor, you must protect the
floor by using (besides the anti-vibration dampers) also an insulating slab, projecting at
least 20 cm on the sides and 40 cm on the front.
- It is compulsory the presence of a suitable
fumes evacuation system in the environment
where the stove is placed.
- It is not compulsory to connect the air pipe of
the stove directly outside (see figure), but it is
necessary to guarantee at least 50m³/h of air.
Grill 800cm² .
- The electrical system must be in accordance
with the law; check the efficiency of the
earthing circuit in a particular manner. The
transmission line must be suited to the power
of the apparatus.
- When you place the stove in a room you must check that the walls are not inflammable and
that inflammable materials such as curtains, wallpaper, etc have not been applied on
the walls. You must place the stove sideways, at a distance less than 20 cm and less than 10
cm at the back. If there is an internal flue it’s advisable to keep a distance of 10cm between
the flue and the wall.
- Do not place inflammable materials at a distance less than 1 meter from the stove.
- We also recommend to keep out of the furnace radiation area, anyway at a distance of at
least 1 m from the warming block, all types of combustible or inflammable materials such
as: beams, wooden fittings, curtains, inflammables.
Flue
The flue of a pellet stove is a very important component because it affects the correct working of
the stove.
The flue must be only for the stove and cannot be used for
other apparatus; you can’t make fixed or movable openings
to connect other air adduction pipes and pipes for plantengineering use.
The flue must be equipped with a chamber for the
gathering of solid materials and possible condensations,
placed under the entrance of the flue outlet duct, so that
you can easily open it and inspect it from an airtight small
door.
The installer has to make sure the opening do not cross
inflammable materials, or in the absence of alternative
solutions, he has to use an insulating protection on the
pipe ( with wall junctions with a diameter of 13 cm at least,
insulating the pipe with insulating materials 1,5-5 cm thick,
with a suitable thermal conductivity), even if it passes near
inflammable materials ( minimum distance 200 mm).
As for the assembly of the pipes you must always use pipes
and junctions with hermetically sealed gaskets.
It’s important that the curvature of 90° provides for a T
junction with inspection; we advise you to use a curve of
45°.
Using nets or filters at the extremity of the flue or any extremity which could turn into a
nest is forbidden. Use only extremity in accordance with the regulation.
The horizontal segments must have a minimum inclination of 3% upward.
As for the connection of the flue, the horizontal segment must be minimum and you
mustn’t exceed 3 meters, the number of direction changes, including that owing to the use
of the T element, mustn’t be bigger than 4, never exceed 6 m of pipes, use curves of 45°
and obey the regulations UNI 10683, using pipes in accordance with the law.
Examples of connections with isolated and non-isolated external pipes
Connections that provide for the use of pipes not larger than 20 cm in diameter, which must have
at the base an inspection system and a draught less than 10 Pa. The internal section must be
uniform, preferably circular; the sides of the pipe must be smooth as much as possible and without
narrowings; the curves must be regular and without discontinuities; the pipes mustn’t be subjected
to deviations from the axis higher than 45°.
It is compulsory the installation of a windproof roof in accordance with the regulations . The T
inspection, placed at the base, can also be placed inside the house ( better if external).
NB: This system always guarantees the fumes evacuation, also in case of non-electric tension
Connection with multiple junctions
Link that is only done in cases of particular disadvantages in rankings. In this case the horizontal
section must have a minimum slope of 3% upwards and must not exceed 3 meters, the vertical
section that goes from the stove to the second curve must be at least 1.5 meters long. The T
inspection, at the base, can also be applied inside the house (preferably external). If there is a
fireplace, it must have a preferably circular internal section; the square or rectangular sections must
have rounded corners with a radius of at least 20mm, rectangular sections, with a maximum ratio of
1.5 between the sides, they must have a constant internal section, free and independent; at the
base there must be an inspection hole. Always make a minimum draught of 10Pa and comply with
the UNI 10683.
NB: In case of obstruction of the pipe, due to failures, or bird's nest, the stove will go on the block
(see the Alarms section) and it will be necessary to clean or repair the pipe, and ventilate the
environment as quickly as possible, otherwise, it will saturate with smoke.
NOTE: The cleaning of the pipe should be done annually.
Chimney pot
The chimney pot must meet the following requirements:
- Have section and internal form equivalent to that of the fuel.
- Have a useful outlet section not less than twice that of the fuel.
- Be constructed so as to prevent the penetration of rain, snow, foreign bodies in the fuel in
such a way that in the event of winds in any direction and inclination, the discharge of the
combustion products is assured (windproof chimney pot).
- The chimney pot must be positioned so as to ensure adequate dispersion and dilution of
the combustion products and, however, outside the reflux area. This area has different sizes
and shapes, depending on the angle of slope of the roof, so it is necessary to adopt the
minimum heights (see figure).
- The chimney pot must be windproof and exceed the height of the ridge or, where it is not
possible, stick to the values indicated in the table.
- Any buildings or other obstacles, which exceed the height of the chimney pot must not be
close to the same chimney.
Draught
The draught in the stove is crucial to have a good performance in specific adverse weather
conditions (rain, fog, snow, altitude, cold, wind), and it is conditioned by the position of the fuel.
Adverse weather conditions that impact negatively on the draft are manifold; particularly
burdensome is the wind, which can be: ascending, horizontal, descending.
- Ascending wind increases the depression and consequently the draught.
- Horizontal wind: it increases the depression, only in the case of a successful installation in
the direction of the wind.
- Descending wind decreases the depression and consequently the draught.
The flue, if disposed on the upwind side, increases the overpressure and consequently, in the
opposite situation, increases the depression, decreasing the draught.
To overcome these drawbacks, the installer must act directly on the stove, modifying the parameter
to adjust the speed of fume extraction and conduct a review of all safety devices. This is particularly
delicate, it must always be carried out by authorized personnel. The ZF company disclaims any
liability, whether civil or criminal, for failure to control by the installer with all safety devices.
