DESCRIPTION
Identification
Attached on the back of the stove, there is an identification plate on
which the following information is written:

Description of the stove
The pellet stove is a heat generator capable of heating air
through the combustion of wooden pellets. The fuel is
loaded in an automated manner. The air present in the
environment is heated by the flame, produced by the
combustion of the pellets, and circulates in the room thanks to the
ventilator. This ventilator emits warm air directly into the room where the
stove is installed.
The safe use of the heater is guaranteed by the fact that on all Moretti
Design products, CE certified systems are installed and they control all
functions and parameters. The advanced software allows for the user a
more simple and immediate comprehension of the heaters functions.
The presence of a thermostat on all Moretti Design products allows the
user to program the on/off switching function of the stove. The large
pellet tank allows for a long period fuel loading procedure, avoiding this
way that the user has to refill the tank too often. The large ash drawer
allows the user to empty it just once a week when it is filled with ash (the
frequency of the operation may vary depending on how long the stove is
used and the quality of the pellets).
INSTALLATION
The stove must be placed on a floor with an adequate load
capacity. If the building does not meet this requirement,
appropriate measures (e.g. load distribution plate) must be taken.
The installation of the stove must ensure an easy access for
cleaning the heater, the flue and the chimney.
The presence of extraction fans in the same room or environment
where the appliance is installed in, can cause problems and should
therefore be avoided.
It is prohibited to install the stove in a small rooms or bedrooms. It
is forbidden to install the stove in rooms exposed to a high risk of
fire, in rooms with an explosive atmosphere or where other heat
generators are already present whose simultaneous presence is
not compatible according to standard regulations.
All local regulations and European standards must be met when the
stove is installed.
Supply conditions and unpacking
The stove is delivered packed together with its aesthetic components. To
unpack the stove, cut the straps and remove the box. Use the proper
equipment for lifting the appliance from the wooden pallet.
Assembling
or the installation of the stove, contact an authorized technician (the
penalty otherwise would be the void of the warranty).
Combustion air
A poor combustion can be caused by poor air circulation in the room and
this often occurs in modern homes that have sealed doors and windows.
The situation also becomes problematic when, on the contrary, there are
air currents inside the room (generated for example by fans). To avoid
this type of disadvantage, it is recommended to install a permanent
ventilation grid in a window or near the stove.
If there is no possibility of connecting the air intake directly to the outside
(see next paragraph), it is imperative to drill a hole on the wall for the
combustion air inlet for both health and safety reasons. It is
recommended the installation of an air grid over the opening and it must
be kept clean.
Combustion air for a hermetic installation
The air required for the combustion must be drawn
directly from the outside through a tube with a 60mm
diameter. The tube must not exceed 5m in length and
must not have more than 4 curves with a 90° angle. It is
recommended the installation of an air grid over the opening and it must
be kept clean (see the following example).
Fume exhaust
To extract the exhaust fumes, a flue must be installed in compliance with
standard regulations. The stove was not designed to share the flue with
other appliances.

Warning:
The chimney must be constructed according to regulation
standards.
For an external installation, use an insulated chimney flue that can
be inspected on the curves
Do not use synthetic materials or aluminium.
Use only stainless steel tubes.
All sections of the fume exhaust must be accessible for inspections
and internal cleaning.
The minimum draft at nominal power must be 10 Pa, the minimum
draft at reduced power must be 5 Pa.
The outdoor section of the barrel must be insulated.
Failure to comply with the above will void the warranty.
Operating conditions
The stove has been designed to be used in ordinary environments,
where there is no danger of possible fire outbreaks or explosions.
Disposal of the combustion waste, must be carried out in accordance
with local regulations. While using the stove, the settings can not be
changed or the protective casings removed. The control devices must be
adjusted by Moretti Design qualified personnel. The maintenance of the
product must be carried out by companies specialized in the
maintenance of heating appliances and authorized by Moretti Design,
which will submit it to all the checks ups required by the local regulations.
Use only 6mm diameter and 30mm average length wooden pellets.
Caution: A stove that has been modified or altered, must be
subjected to further verifications in compliance with the law. The
improper connection of the stove to the flue and the non-
compliance of regulations for the installation of air vents can cause
serious danger to people and will void the warranty.

Residual risks
Certain parts of the stove, in particular the glass and flue, while in use
overheat and can cause burns, do not touch or handle unless with the
utmost care. The electrical parts can cause serious damage, do not
touch these parts without having disconnected the cable from the main
power supply.
SAFETY DEVICES
Breakage of the exhaust fan: If for any reason the fan breaks, a safety
measure intervenes and blocks the pellet flow (Er02), an alarm goes off
and stops the stove’s function.
Breakage of the auger motor: If the auger motor stops feeding pellet,
the system still continues to function on minimum levels then an alarm
goes off and the stove blocks (Er12, Er03).
Failed ignition: If there is a failed ignition, the stove goes into safe
mode and then into block (Er12). Unblock the stove and check if the
burner is clean and positioned properly before attempting another
ignition.
If the burner is not cleaned, the next ignition may cause a little
deflagration inside the combustion chamber. If this occurs, the
manufacturer will not accept any responsibility for damage to
persons, animals or things.
Electrical protection: The system is protected with a 4 A fuse that is
located on the back of the stove. To replace it, extract the tray next to the
switch only after disconnecting the power cable from the power supply,
replace the broken fuse and reinsert the tray, if the new fuse immediately
breaks, contact a technician.
Exhaust fume safety: If there are any anomalies with the smoke
expulsion from the system, an alarm will go off and the system will block
(Er02).
Pellet safety: If the temperature inside the pellet tank exceeds the
safety level, the system blocks (Er01). The reinstatement is automatic.
Power failure: If there is a short power failure in the power supply, the
system will go into block (Er15), if the lack of electricity is not brief, the
stove could release a small quantity of smoke in the room, if the air
intake has not been correctly connected to the outside. This is caused
by the scarce draw of the chimney flue and does not represent any
risk for one’s safety. When the power comes back, the system
switches itself off.
Warning: In the case the chimney catches fire, call the fire brigade.
MINIMUM SAFETY DISTANCES
Keep fuels and flammable substances at an adequate distance from the
stove. or minimum distances from flammable materials, one can refer
to the products identification plate located on the back of the stove.
Caution: For some models the minimum safety distance from
flammable materials may be different than those shown in the
figure below. Therefore, always refer to the product identification
plate generally located on the back of the stove to ensure minimum
safety distances for the specific model.
Note: If one wants to install the stove near a non-flammable wall, it is
possible to place it directly in contact with the wall, as long as it does not
obstruct any access to the electrical components or connections or
maintenance interventions.
FIRST IGNITION
Caution: The first ignition must be carried out by MORETTI DESIGN
qualified personnel that must also perform an overall check up of the
system.
All local and National laws and European standards must be met
when using the appliance.
Positioning the deflector
Before turning on the stove, it is necessary to insert the deflector inside
the combustion chamber (see dedicated manual).
Note: Once a month remove and clean the deflector. A failure to clean
can compromise the proper function of the stove.
Positioning the antenna
The position of the antenna, is very important in order to optimize the
transmission and reception of radio signals between the display radio
and stove itself for the management of the various functions.
Models with external antenna (metal sheet coated and Relax)
Make sure that the white tip of the antenna does not remain in contact
with any metal parts of the stove. Perform a signal quality test by using
the Radio Test function (page. 13) before switching the stove on. If the
signal is not optimal, remove the holding clip and unroll out the antenna
completely.
Models with internal antenna (glass or majolica coating)
Distance in mm

7
The antenna remains inside the stoves coating. Make sure that the white
tip of the antenna does not remain in contact with any metal parts of the
stove, but it remains in contact with the glass or majolica coating.
Perform a signal quality test by using the Radio Test function (page. 13)
before switching the stove on.
Pellet loading
ill the fuel tank with wooden pellets. Open the lid and
then pour the fuel in. It is recommended to close the pellet
tank lid properly.
Use only wooden pellets with a 6 mm diameter and 30mm maximum
length, EN PLUS certified class A1.
Warning: Before filling the tank, make sure that at the bottom there are
no odd materials.
Ignition mode
Make sure that the stove is connected to the electrical power and that
the switch on the back is on position “I”
ill the auger by using the LOAD function (see page 12). During the
ignition or even in run mode, the front door must always be kept closed.
Before turning on the stove, empty out the burner once the initial load
function has been carried out.
See DISPLAY RADIO (page 10) on how to turn on the appliance,
adjust the room temperature and combustion power level and for
more information regarding the various menus.
COMBUSTION
The combustion is a chemical reaction in which a fuel (pellets) and an
oxidiser (air) are combined, thanks to an ignition (resistance), in order to
produce heat. They should be dosed in suitable proportions so that the
combustion can take place. ollowing are some examples with a
description and adjustment procedure to obtain an optimal combustion.

CONNECTOR
FCS (Fire Control System)
It is an automatic combustion control system that
maintains the products high efficiency. The system
automatically adjusts the fuel (pellets) and combustion air
dosage according to the draw read from the flowmeter
sensor located inside the stove.
Even with the CS system activated, it is recommended to check the
quality of the flame by comparing it with the images of the following
examples.
In the case of a NON OPTIMAL combustion, despite the CS system is
active, contact an authorized technician.
Calibration
Note: On models where the FCS (or MCS) is installed on, it is possible
to adjust the automatic combustion correction range in MCS Calibration.
On models without the CS it is possible to manually regulate the
combustion through the Auger Calibration and Fan Calibration
functions.
Example 1
NON OPTIMAL combustion, the flame is high and weak and is of an
intense orange colour also a large amount of unburned pellets are left
over inside the burner.
• Regulation on models with FCS: irst of all check the closure
of the front door and tightness of the gaskets. Increase the MCS
Calibration setting one point at a time (from 0 to +5) until the
example 3 condition is achieved.
• Manual regulation on models without FCS: irst of all check
the closure of the front door and tightness of the gaskets. Then
increase the Fan Calibration setting one point at a time (from 0
to +5). If it is not enough, reduce the Auger Calibration setting
one point at a time (from 0 to -5) until the example 3 condition is
achieved.
Example 2
NO
NO

8
NON OPTIMAL combustion, the flame is too stretched and a large
amount of burning pellets are blown out of the burner.
• Regulation on models with FCS: Reduce the MCS Calibration
setting one point at a time (from 0 to +5) until the example 3
condition is achieved.
• Manual regulation on models without FCS: Reduce the Fan
Calibration setting one point at a time (from 0 to +5). If it is not
enough, increase the Auger Calibration setting one point at a
time (from 0 to -5) until the example 3 condition is achieved.
Example 3
OPTIMAL combustion, the flame is vibrant of a yellow/white colour with
a small amount of burning pellets inside the burner. It is not necessary to
adjust any settings in the Calibration menu.
or all three of the examples, it is advised to evaluate on the spot all
necessary adjustments.
CONNECTION AND DESCRIPTION ON HOW A
DUCTED STOVE OPERATES
Ducted pellet stoves include, in addition to the front
ventilator, also ventilators dedicated for ducting warm air.
There are models where there is only one ventilator
installed, these stoves are equipped with a single hot air
duct, while there are other models where there are two
ventilators installed, these stoves are equipped with two
hot air ducts.
The ducts for conveying warm air from the stoves output (80 mm) must
not exceed 7 meters in length and must not have more than 4 curved
sections. We recommend the use of smooth insulated rigid steel pipes.
YES
Optional
or a proper use of a ducted stove, it is appropriate that for each ducted
output a room sensor (model NTC 10k at 25°) or an ON/O thermostat
or a wireless thermostat is connected. A stove without the above
components connected can never go into Modulation. Observe the
technical data sheet on the product manual in order to verify where the
connecters for connecting the sensors or thermostats are located on the
back of the stove.
How a ducted stove operates
Assuming to use a stove with two ducted outputs complete with
thermostats or sensors connected, if we set one of the thermostats at
18°C, the other at 19°C, the local room temperature thermostat at 20°C
and the combustion power at P5, the behaviour of the stove will be the
following:
When one of the three environments reaches the set temperature, the
fan for that environment will run at minimum power while the stove will
automatically lower the combustion power level to P4 and the other fans
will run at the speed of the new power level set (P4).
When a second room reaches the set temperature, the fan relative to
that environment will run at minimum power as the stove will
automatically lower the combustion power level to P3 and the remaining
fan will run at the speed of the new power level set (P3).
When the third and last environment reaches the set temperature, the
relative fan will operate at a minimum and the stove will go into
Modulation.
That being said, if the ducted outputs are not connected to a thermostat,
the fans will always run at the set power level and the stove will never go
into Modulated.
The fans of the ducted outputs can not be excluded or deactivated,
because if they are switched off it would cause an overheating of the
stove with possible damage to the structure of the stove itself and the
fans.
The fan speeds can not be adjusted by the user, for each combustion
power level the fans turn at a relative speed.
Pot: Auto setting on ducted stoves
It is possible to select automatic combustion (Pot: Auto) in the same way
a combustion power is selected. By selecting Pot: Auto on a ducted
stove, the system automatically regulates the combustion power level
and adjusts it to the room temperature set on the display radio. As a
result, the speed of the heating fans (front + ducts) will adjust to the
power level as the room temperature approaches the set temperature.
Once the room temperature reaches the one set on the display radio, the
ducted stove heating fans (front + ducts) will run at the minimum speed.

DISPLAY RADIO
Introduction
The display radio (white) is a wireless device for the stove
to which it is associated with and through it, it is possible
to control and monitor the systems functions in real time.
The main features are:
- Battery powered remote control.
- Room thermostat.
- Control device for the operating parameters.
Warning: The system works by using the 433.92 MHz ISM radio band
frequency. The range of the device can be reduced significantly in the
case of a noisy environment: other appliances such as wireless
headphones, video, etc, may affect the performance of the system. Make
sure of the presence of such appliances and turn them off or limit their
use. In the case of interaction of multiple remote controls with more
stoves, one must associate each display radio with a specific stove (see
"Code change” page 13).
The display lights up when the button is pressed and the main
screen appears.

Run Mode
After the ignition, the system goes into Run Mode. During this phase the
heating fan is activated and the system operates on the set combustion
power level.
Modulation
During the Run mode, the aim of the stove is to reach the set room
temperature, when this goal is achieved, the system goes into
Modulation where the fuel consumption is minimal and the fan will run at
the lowest speed power setting.
Combustion power setting
It is possible to modify the combustion power level at any time, but the
change is effective only in Run Mode. The power level ranges from 1 to
5. Increasing the power equals to a high pellet consumption and the
heating fan turning at high speeds.
Automatic combustion (Pot: Auto)
It is possible to select the automatic combustion setting (Pot: Auto) in the
same way the combustion power level is selected. By selecting Pot:
Auto, the system automatically adjusts the combustion power and
adjusts it to the room set temperature on the display radio. The higher
the difference between the actual room temperature read and the one
set on the display radio, the higher the combustion power level the stove
will automatically set and vice versa.
Eco Clima
When the room temperature is reached, the control unit reduces the
pellet consumption to a minimum by activating the Modulation phase,
then the system will verify if this temperature is maintained for a set
period of time and if this occurs, the stove will automatically switch to
Standby (the stove turns off).
By using this mode it is necessary to make sure that after each
automatic turn off, the burner must be cleaned in order to
guarantee a correct automatic ignition.
Note: The stove operating on the Eco Clima mode, can turn itself on and
off several times during a day. This though can consume the ignition
resistance for the automatic ignition.
Note: Turn off the stove in case of damage or malfunction.

In the following example we have:
Tx = 624 (Transmissions from the display radio to the stove)
Rx = 611 (Successful receptions of the signal from the stove)
Er = 11 (Missed transmissions not intercepted by the stove)
In this example we have a very good signal quality.
