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.

10 MODES OF OPERATION
Premise
The installer must make the first start by taking precautions, and must ensure that the safety devices
are working properly (Vacuum gauge, 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
evidence 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 mandatory verification of the safety are over, 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 0 to position 1 as 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 P4 for a few seconds. The successful ignition is indicated in the display
with the message "START" as (Figure 3). This phase lasts for a time given by the parameter
PR01.Under these conditions, the stove will go in the state of preheating, the glow plug turns on
(shown by the glow plug LED) and so does the fan fume extraction. Malfunctions during the ignition
phase are shown on the display and the heater goes into an alarm state.
(refer to chapter 9).
Figure 3
10.2 Pellet uploading
After about 1 minute the uploading phase begins, the display scrolls the message "LOAD PELLET".
In a first step the auger provides to load the pellets in the brazier for a time given by the parameter
PR40 (auger LED lit), the speed of the fumes is defined by parameter PR42 and the glow plug is
always lit (glow plug LED lit). 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 glow plug remain in the previous state. If the stove does not power up 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 glow plug is lit. (Figure 4).

10.3 Fire Present
After the fume temperature has reached and exceeded the value contained in the parameter PR13,
the system goes into power mode displaying "FLAME LIGHT" on the display. 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 flashing on) and the glow plug is switched off (glow plug LED off).
(Figure 5) Any anomalies will stop the board and this will report the error. (refer to chapter 9).
Figure 5
10.4 Stove on working mode
After the flue fumes temperature has reached and exceeded 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". The power is set by holding down the P5 and P6
and the room temperature can be set by pressing the P1 and P2. (Figure 6). If the fumes temperature
reaches the threshold set by parameter PR15, the fan air exchanger lights. (led exchanger on).
Figure 6
During this phase, after a time given by the parameter PR03, the stove performs a cleaning of the
brazier. The display will scroll the inscription " CLEANING FIRE-POT ", the auger is turned on (auger
LED on) with a speed given by the parameter PR09, the fumes fan speed given by parameter PR08.
(Figure 6a) Once the given time by the parameter PR12 has passed, the stove is back in working state.

10.8 Stand by
If enabled in the menu, standby function allows you to turn off the stove once the conditions
explained below are met. 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 " STANDBY " and the remaining minutes. (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 heat
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 runs "WAIT COOLING-" on the display. The auger is off (auger LED off), the
exchanger is off (exchanger LED off), as well as the fumes fan. (Figure 10b).

13 Maintenance, cleaning, testing the stove
All cleaning and inspections must be carried out when the stove is cold, with the plug disconnected,
using gloves and mask. The ZF company does not assume civil or criminal liability, in case you clean
or test the stove when this is on, still warm, with the voltage supply switched on and without proper
protective equipment.
Daily cleaning
Brazier Cleaning
The cleaning of the brazier is crucial for the proper operation of the stove; it should be performed
daily before each start. Lift the brazier from its seat, clean the inside of the brazier with a brush by
removing combustion residues and free all the air passages with a screwdriver or a pointed tool (not
supplied with the stove). This operation is particularly necessary when using a pellet of poor quality;
it is also good to check and clean the brazier support, if there are residues inside they should be
removed with a spoon or with a vacuum cleaner. A good cleaning of the brazier ensures good
combustion and, consequently, a high yield of the stove.
Cleaning the combustion chamber and ash drawer
The cleaning of the ash and combustion chamber should be made when the ash reaches the edge of
the same drawer; it is strictly forbidden to
light the stove if the ash goes beyond it. Every
day when you clean the brazier also check if
the drawer is empty. This maintenance must
be done when the stove is cold; it is
prohibited to use water to cool the ash or to
clean the inside of the stove. You can use the
vacuum cleaner, the drawer must be replaced
correctly and get to the bottom and there
should be no residue of ash in front of or
underneath it, if residues are present, it could
be interfering with the closing of the door,
therefore create an air leak in the combustion
chamber.
Cleaning the glass
The glass is self-cleaning and then, while the stove is in operation, a film of air flows along the
surface of the same, taking away the ash and dirt; Nevertheless after a few hours, a grayish flap will
appear and it has to be cleaned at the first shutdown of the stove. The dirt the glass also depends
on the quality and quantity of pellets used. When this is done, always observe if the gray seal around
the glass is in good condition; if you fail to control the efficiency of this seal the operation of the
stove may be compromised. Pellets of poor quality, dirty brazier, may nevertheless cause more dirt in
the glass.
Attention: in case of broken or damaged glass, do not try to turn on the stove.
Monthly cleaning
Open the door of the stove, by means of a vacuum
cleaner remove all the ash, also clean the residues
attached to the inner walls of the stove with a brush.
Remove the brazier to proceed with the removal of
interior walls.
Remove the internal bulkhead, taking it by the two lower
edges, if this operation proves to be difficult , use an
extraction forceps.
Remove the two side supports by turning up after
you have done this remove the
beat flame top.
To remove the beat flame top, take it with one hand in
the middle, pull in a linear way down once you see all
the spin box, rotate to remove it from the combustion
chamber of the stove. Take the vacuum cleaner and
clean the inside.
At the bottom of the combustion chamber behind the
support of the brazier there is another bulkhead to
remove, grab her by the edge and pull up.
Removed this piece, the two rear bulkheads are released,
to remove them, simply take them off. Even at this stage
take the vacuum cleaner to clean the entire inner part of
the stove, if present of the residue pasted, carry a brush
to remove it from all surfaces.
When all surfaces are clean, remove the ash collection
drawer and thoroughly clean even the latter.
Finally, use a screwdriver to remove the cap that is

16 Duct
The duct system allows to carry and distribute the heat generated from the heater also in
other environments different from the one where the machine is positioned.
Connection
The connection to the heater can be of two types:
- Connecting on top of the stove only through a tube
- Connection on the back of the stove using two pipes
The company Z.F. LTD recommend using smooth tubes, with sweeping curves that is
isolated and insulated to prevent heat loss along the way, also should not exceed 10
meters in overall length of the system because in this case it incurs the loss of heat
produced from the stove.
Regulation
The adjustment of the channeling can happen in two ways depending on the type of stove
you have:
- Manual Adjustment
- Automatic Adjustment
Automatic Adjustment
The adjustment of the air flow in this case is managed directly on the main display of the
heater, through the pressure of a few buttons, allowing independent adjustment of the two
additional fans. For each of the two fans are different possible types of regulation (see
table below). To change the parameters, press on button 1 (fan 2) and button 2 (fan 3).
