7 Installation
Recommendations 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 space 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 (fireplace, etc.).

Space and distances
It is essential to check the space where the stove will operate for an optimal operation.
-The volume of the house or the working space mustn’t be smaller than 40m³.
-There has to be a permanent opening of airflow to the outside of the place of the installation,
minimum 800 cm², not obstruable and protected with a permanent grill, or the stove has to be
connected to the outside by an air intake tube (as shown below), do not exceed 80 cm in length
with 2 curves maximum.
-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
flammable materials.
-If the stove is installed in a room with
wooden or flammable floor, you
must protect the floor by using (in
addition to the anti-vibration feet
provided) also an insulating slab,
protruding at least 20 cm on the side
and 40 cm on the front.
-In the space, where the stove is placed, it is compulsory the presence of a suitable fumes evacuation
system.
-It is not compulsory to connect the air intake tube of the stove directly outside (see picture) but it is
recommended for a better efficiency (energy-saving). In any case, it is necessary to guarantee at
least 50 m³/h of air. Grill 800 cm².
-The electrical system must be in accordance
with the law; in particular, check the
efficiency of the earthing circuit. The supply
line must be of an appropriate section to the
power of the device.
-When you place the stove in a room you
must check that the walls are not flammable
and that flammable materials such as
curtains, wallpaper, etc. have not been
applied on the walls. You must place the
stove at a distance not less than 20 cm laterally and not less than 10 cm at the back. If there is an
internal flue it’s advisable to keep a distance of 10 cm between the flue and the wall.
-Do not place flammable materials at a distance less than 1 meter from the stove.
-We also recommend to keep out of the thermal radiation area, and anyway at a distance of at least
1 m from the warming block, all types of combustible or flammable material such as: trusses,
wooden fittings, curtains, flammable liquids.

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 needed only for the stove and cannot be shared with other devices; you can’t make fixed
or movable openings to connect other air adduction pipes and pipes for plant-engineering use.
The flue must be provided 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 air-tight small door.
The installer has to make sure that the opening do not cross
flammable 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 though it passes near flammable 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; it is advisable to use curves 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 as a result of 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 include the use of pipes not larger than 20 cm in diameter, which must have at the base
an inspection system and a forced draught minimum 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 missed electric tension
Connection with multiple junctions
Connection that is exclusively done in cases of particular disadvantages in positioning. 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, the rectangular sections, with a maximum ratio of 1.5 between the sides, must have
a constant internal section, free and independent; at the base there must be an inspection hole. Always
verify a minimum forced draught of 10Pa and follow the regulation UNI 10683.
NB: In case of obstruction of the pipe, due to damages, or birds’ nest, the stove will stop (see the alarms
section) and it will be necessary to clean or repair the pipe, and ventilate the room as quickly as possible,
otherwise, it will saturate with smoke.
NB: The cleaning of the pipe should be done annually.

Chimney pot
The chimney pot must meet the following requirements:
-Have the section and the internal form equivalent to that of the flue.
-Have a useful exit section not less than twice that of the flue.
-Be constructed to prevent the penetration of rain, snow, foreign bodies in the flue so that in case of
winds in any direction and inclination, the discharge of the combustion products is assured
(windproof chimney pot).
-The chimney pot must be positioned to guarantee an 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 peak or, where it is not possible,
comply with 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 pot.

Draught
The draught of the stove is essential to have good performances in specific adverse weather conditions
(rain, fog, snow, altitude, cold, wind), and it is conditioned by the position of the flue. Adverse weather
conditions that affect negatively the draught are various; 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 right installation in the direction of
the wind.
-Descending wind: decreases the depression and consequently the draught.
The flue, if placed in 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 verify all safeties. This operation is particularly delicate, it must
always be carried out by authorized personnel. The ZF company declines any liability, whether civil or
criminal, for missed control by the installer of all safeties.

The pellet
To obtain the maximum performance, the ZF company suggests to use pellets of the quality prescribed by
the regulations DIN51731.
Length: 30mm
Diameter: 6mm
Calorific value: 4.9 ÷ 5.3 kWh / kg
Humidity max: 6%
The pellets must be stored in a dry place away from heat sources. The ZF company assumes no
responsibility for malfunction due to the use of poor quality pellets.
9 First ignition
Warning
The first ignition will have to be carried out by a qualified technician who will have to check:
-That all the regulations mentioned above and the current regulations in the place of installation
have been applied.
-The correct installation: of the stove, the flue, the chimney pot.
-That there is no risk of damage to the stove or to the room of installation. In case of problems, the
ZF company assumes no liability both civil and criminal.
First steps
Check that there are no objects on the stove (manual included) and proceed as follows:
-Fill the hopper with pellets, opening the upper door and closing it again, making sure that no
foreign body is in the hopper. Take off the cover of the hopper only during its charging.
-Check that the brazier is well positioned in its place.
-Check that the door is hermetically closed.
-Supply power, put the general switch ON (it is placed in the back down side); the control display will
light up.
-During the first few times, there may be cases of unpleasant smells due to the presence of greases
and oils on the components used during the production phase. Ventilate the space and avoid
staying there for long periods until the smells disappear.

10 MODES OF OPERATION
Premise
The installer must make the first start by taking precautions, and must ensure that the safeties are working
properly (pressure switch, hopper temperature protection etc...). Any anomalies with the installation can not
be attributed directly to the ZF company. The installer must carry out any other try he deems necessary and
verify the operation of the buttons on the console.
10.1 Igniting the stove
Once the installation of the stove and the compulsory verification of the safeties are over, the operation
phase begins. To power the stove, simply connect the cable to the electrical
outlet, press the power switch located on the back of the stove at the bottom,
moving from position 0to position 1as shown in (Figure 1)
Figure 1

Before switching on the stove, the display appears as shown in Figure 2.
Figure 2
To turn on the stove, press on P3 for a few seconds. The successful ignition is indicated in the display with
the message " START" as in (Figure 3) and with the ON/OFF LED flash. This phase lasts for a time given by
the parameter PR01. Under these conditions, the stove will go in the state of preheating, the ignition turns
on (shown by the ignition LED) and so does the smoke extractor. Malfunctions during the ignition phase are
shown on the display and the stove
goes into an alarm state. (refer to
chapter 12).
Figure 3
10.2 Pellet loading
After about 1 minute, the pellet loading phase begins, the message " LOAD PELLET" passes on the display
and the ON/OFF LED flashes. In a first step the auger provides to load the pellets in the brazier for a time
given by the parameter PR40 (auger LED on), the speed of the fumes is defined by parameter PR42 and the
ignition is always on (ignition LED on). In the second phase, after the time of the parameter PR40 has
passed, the auger turns off (auger LED off) for a time given by the parameter PR41, while the speed of the
fumes and the ignition remain in the previous state. If the stove does not turn on after this phase, the auger
turns on for a period given by the parameter PR04, the fumes speed is given by the parameter PR16 and the
ignition is on. (Figure 4).

10.3 Fire present
After the fumes temperature has reached and overcome the value contained in the parameter PR13, the
system goes into power mode displaying " FLAME LIGHT" on the display and the LED ON/OFF flashes. In
this phase, it is checked that the temperature remains stable for a predefined time given by parameter PR02.
The fumes speed is given by the parameter PR17, the auger will turn on for a time given by the parameter
PR05 (auger LED intermittent) and
the ignition is switched off (figure
5). Any anomalies will stop the
board and this will report the error
state. (Refer to chapter 12)
Figure 5
10.4 Stove on working mode
After the fumes temperature has reached and overcome the value contained in PR13 and maintained it for
at least a time PR02, the stove goes into working mode which is the normal operating. The display will show
the word "Work" and the LED ON/OFF is on. The power can be set by holding down the P2 button and the
room temperature can be set by
pressing the P1 button (Figure 6). If
the fumes temperature reaches the
threshold set by parameter PR15,
the air exchanger fan lights up.
(led exchanger on).

To change the room temperature it is enough to act on the button P1. The display shows the set room
temperature (SET temperature). Thus acting on the buttons P1 (decrease) and P2 (increase) it is possible to
change the value. After about 5
seconds the value is saved and the
display returns to the normal
mode, or press P3 to exit. (Figure 8).

10.7 The room temperature reaches the set temperature
(SET temperature)
When the room temperature has reached the set value, the heating power of the stove is automatically
decreased to the minimum value. Under these conditions, the display shows the message
"MODULAT-" (Figure 9). If the room temperature decreases below the set one (Set temperature) the stove
goes back to "Work" mode and to the power previously set (Set power).

10.8 Stand by
If enabled in the menu, standby function allows to turn off the stove once the conditions explained below
are respected. It is enabled if, at a given time by the parameter PR44, the room temperature is higher than
the set temperature (Set environment) plus the parameter PR43. The display shows "GO-STANDBY" and
the minutes left. (Figure 10).
Figure 10
At the end of the time given by the parameter PR44, the display shows the message "WAIT COOLING". In
this state, the stove has turned off the auger (auger LED off), the exchanger switches off when it reaches the
threshold given by the parameter PR15 and the LED ON \ OFF flashes. (Figure 10a).
Figure 10a
When the fumes temperature reaches the threshold given by the parameter PR13, the stove goes into
stand-by mode and "STOP ECO TEMP GOOD" passes on the display. The auger is off (auger LED off), the
exchanger is off (exchanger LED off), as well as the smoke extractor. (Figure 10b).
Figure 10b
If the room temperature drops below the set temperature (Set environment) minus the threshold given by
the parameter PR43, the stove will switch on again.
