10-FIRST START-UP
Technical Dept. - All rights reserved - Reproduction is prohibited
PRECAUTIONS BEFORE START-UP
GENERAL PRECAUTIONS
Remove all parts that may burn from the brazier and the glass (manual, various adhesive labels or any polystyrene).
Check that the brazier is positioned correctly and rests properly on the base.
The rst start-up may not be successful as the feed screw is empty and does not always manage to load the required
amount of pellets in time to light the ame.
ELIMINATE THE ALARM CONDITION OF A FAILED START-UP BY POSITIONING THE OF THE EMERGENCY PANEL TO OFF FOR
ABOUT 20 SECONDS AND BRINGING SELECTOR “D” BACK TO THE REMOTE POSITION. REMOVE THE PELLET LEFT IN THE
BRAZIER AND REPEAT THE START-UP. (SEE “SAFETY DEVICES/ALARMS” PARAGRAPH)
If after repeated attempts, the ame fails to ignite, despite a regular ow of pellets in the brazier, which must rest snugly against the
slots. If no anomaly is found during this inspection, there may be a problem with the product components or installation may not be
correct.
REMOVE THE PELLETS FROM THE BRAZIER AND CONTACT AN AUTHORISED TECHNICIAN.
Do not touch the boiler during the rst lighting, as it is during this phase that the paint sets. If you touch the paint,
you may expose the steel surface.
If necessary, touch up the paint with the spray can of the specic colour. (See“Pellet stove accessories”)
It is good practice to ensure eective ventilation in the room during the initial start-up, as the boiler will emit some
smoke and smell of paint.
Do not stand close to the stove and, as mentioned, air the room. The smoke and smell of paint will disappear after about an hour of
operation, however, they are not harmful in any case.
The boiler will be subject to expansion and contraction during the lighting and cooling down stages, and may therefore make slight
creaking noises.
This is absolutely normal as the structure is made of laminated steel and must not be considered a defect.
It is extremely important to make sure the boiler does not reach high temperatures straight away, but to increase the temperature
gradually using low power at rst.
This will prevent damaging the ceramic or serpentine stone tiles, the welds and the steel structure.
DO NOT EXPECT HEATING EFFICIENCY IMMEDIATELY!!!

11-REMOTE CONTROL MAX
GENERAL FEATURES OF THE LCD REMOTE CONTROL
The remote control works at a transmission frequency of 434.5 MHz. Power the product with 3 AAA batteries as follows:
Remove the battery compartment cover by pressing and lifting according to the arrow
Insert the batteries observing the correct polarity (+) and (-)
Close the battery compartment cover.
When the remote control is powered it automatically prompts to set the time.
The remote control has a special icon on the display to indicate when the batteries are almost at. If the at battery icon appears, the
batteries are almost at and the remote control is about to switch o.
Used batteries contain metals which are harmful to the environment, so they must be disposed of separately in
appropriate containers.

REMOTE CONTROL OPERATION
General rules
By pressing key Afor 1” the product is switched on and o. Key Cis used to make all changes. Key Eis used to conrm the changes. By
pressing key Bone selects the product operating mode. Via key Done browses the FAN and SLEEP setting. Whichever the mode is, press
key Abriey (or leave the keypad idle for 7”) to go back to the initial display.
INITIAL SETTINGS
Setting the time
Both with the remote control on and o, by pressing keys B+Eat the same time for 3”one accesses the time/day setting mode.
The hour digits will start to ash; they can be changed with key C. By pressing key Ethe changes are conrmed.At this point the minutes
digits will start to ash.
Follow the same modify/conrm procedure, one will then go onto the time display mode (12h or 24h) and nally
the day will start to ash. Conrm this data to exit the settings.
NOTE: each time the remote control is powered, the time is reset and the display automatically enters the time setting mode.
°C – °F setting
Only with the stove switched o, by pressing key Bfor 5”one changes the unit of measure of the temperature, from Celsius to Fahrenheit
and vice versa.
SETTING THE OPERATING MODE
With the remote control switched on, key Ballows to set one of the 4 product operating modes. Figure 1-2-3-4
displays the 4 basic displays, respectively: Manual, Automatic,Timer and Eco mode.
MANUAL Mode (MAN)
In this mode one can set the ame power manually (5 levels - act directly on key C to change). Figure 1
AUTOMATIC Mode (AUTO)
In this mode one can set the desired room temperature, and the stove will modulate the ame power automatically to reach the
temperature. Figure 2
If a fan is AUTOMATICALLY set, its speed depends on the power that is running the stove:
In the case of power level 1: V=1
In the case of power level 2: V=2
In the case of power level 3: V=3
In the case of power level 4: V=3
In the case of power level 5: V=3

MANUAL POWER FUNCTION
this function allows you to set the power of the ame from a minimum of 1 to a maximum of 5.The power levels correspond to a dierent
value of fuel consumption, setting 5 heats the room in less time and setting 1 can keep the room temperature stable for a longer period of
time.The set ame is automatically set to a minimum when the set temperature value is reached.
if the bars are all full, the stove is on ame power 5
if only one bar is full, the stove is on ame power 1
If the ventilation is MANUALLY set, the function which limits the maximum power of the stove according to the ventilation is enabled.
COMFORT AIR (3 FANS): maximum power level = total of the levels of ventilation/2.
AIR: maximum power level = twice the total of the levels of ventilation
Even if the power limit is enabled, the display on the remote control does not consider the power limit for ventilation eect.

TIMER Mode (TIMER)
Select this operating mode to switch the product on and o automatically, according to 6 customised time slots (P1 – P6). The following
can be set for each time slot:
• Switch-on time
• Switch-o time
• Desired room temperature in the time slot
• Days of the week in which the time slot is active
When the stove is switched on (manually via key Aor automatically via a time slot) the product works in the
automatic mode described above. A time slot appears automatically when it is active (P1 in gure 3) and the desired temperature is
changed according to the value set in the time slot. However, the user can always modify this value as desired and in real time.
Refer to the relevant paragraph to learn how to set the time slots.
ECO Mode (ECO)
This mode is activated/disabled with the remote control switched on by pressing key Bfor 5”.
ECO is an automatic mode with the only dierence that if the set temperature is reached and remains so for the following 20 minutes
(despite ame modulation), the product switches o and remains on stand-by until the room temperature drops 2 degrees below the
desired temperature (and in any case for at least 5 minutes from the last shutdown).The product is then switched on again. Figure 4
If the room is not suciently insulated, ame modulation does not allow the set temperature to stay satised for 20 consecutive minutes
and the product will not switch o.
NOTE: It is recommended to use the ECO mode only in well-insulated rooms in order to prevent start-up and shutdown
from occurring within short periods of time.
The remote control remains on even when the product is o when in ECO mode, in order to indicate that this shutdown is only
temporary. Obviously, if the product is switched o via key A, ECO mode is exited and the product remains o.
Up to 6 automatic start-up and shutdown time slots (E1 – E6) can also be set in ECO mode, which are independent
from those of TIMER mode (P1 – P6). If they have been activated, TIMER-ECO appears on the display (gure 5) permanently, even if the
remote control is switched o.
Refer to the relevant paragraph to learn how to set the time slots.
NOTE: If the remote control is switched o due to TIMER, ECO cannot be restarted until the user intervenes (key A) or
when the next valid time slot starts. Combined use of TIMER and ECO modes requires a good knowledge of the product
operating logic.

Room ventilation
Room ventilation can be adjusted as desired in all 4 operating modes described above (Manual, Automatic, Timer, Eco). Simply perform
this operation: from the basic display, press key D to access theVENTILATION adjustment mode (Fig. 6). Then press key C (arrows) to set the
desired ventilation by selecting one of the 5 levels available, independent from the ame level.
The“auto”option can also be selected, which automatically links the room ventilation speed to the ame level.
In short:
ame set on 1 > ventilation set on 1; ame set on 3 > ventilation set on 3; ame set on 5 > ventilation remains set on 3 (for silent
operation as it is in automatic mode).
In products with 2 or 3 room fans (comfort air models) via key D one can scroll and set the speed of the individual fans (identied with 1,
2 or 3 above the level bars).
NOTE: In the event a replacement remote control is purchased, if you need to change the default setting, proceed as
follows: with the remote control switched on press buttons D + E at the same time for 10 seconds (until the ashing
number appears). Press key C to select 1, 2 or 3 according to the product to which the remote control is to be paired, and
press E to exit.
IMPORTANT! Choosing the right number of fans can become a decisive factor to ensure the stove works correctly. Therefore
ensure an authorised technician conducts the settings.

14-SAFETY DEVICES
Technical Dept. - All rights reserved - Reproduction is prohibited
SAFETY DEVICES
The product is tted with the following safety devices.
SMOKE TEMPERATURE PROBE
It detects the temperature of the smoke, thereby enabling start-up or stopping the product when the temperature drops below the preset
value.
PELLET HOPPER TEMPERATURE PROBE
If the temperature exceeds the preset safety value, it immediately stops the product, which must cool down before the stove is restarted.
ELECTRICAL SAFETY
The product is protected against power surges by a general fuse located in the control panel on the back. Other fuses that protect the
electronic boards are found on the latter.
SMOKE FAN BREAKAGE
If the fan stops, the circuit board promptly blocks the supply of pellets and the alarm is displayed.
GEAR MOTOR BREAKAGE
If the gear motor stops, the product switches o and the relative alarm is signalled.
TEMPORARY POWER CUT
If a power cut occurs during operation, the product automatically sets itself in cooling mode when the power is restored and then it
restarts.
FAILED START-UP
If no ame lights during start-up, the product will go into alarm conditions.
TAMPERING WITH THE SAFETY DEVICES IS PROHIBITED.
It is possible to relight the product and therefore restore the automatic operation of the probe only after having eliminated the cause of
the intervention of the safety system. This manual will help you understand which anomaly has occurred, and explain how to intervene
according to the alarm message displayed on the appliance.

14-SAFETY DEVICES
Feed screw loading function
This function can only be activated when the stove is o and allows the pellets to be loaded into the loading system (feed screw). It can
be used each time the pellets nish in the hopper (see alarm A02). It is useful to prevent failed start-ups (alarm A01) due to the hopper
being empty.
Enable the function as follows:
• Set the rst selector to OFF
• Set the second selector to MED
• Make sure that OFF appears on the display because this function can only be activated with the stove completely cold (o) and the
selector set to OFF.
• Press the TEST key 3 times consecutively within 2 seconds
• “OnPlt” will appear on the display in two subsequent intervals.
• Press the TEST key once again when the pellets begin to fall into the brazier to end the FEED SCREW LOADING function or wait for

qualied technician must be contacted for maintenance.
Exiting the alarm conditions
Follow the procedure described below to restore normal stove operation after an alarm has been triggered:
• Put selector D on the rear emergency panel on OFF for a few seconds, until the 3 digit alarm identity code disappears. The red LED
stops ashing and the sound signal is silenced by performing the steps below.
• Put selector D back in the REMOTE position, to control the operation of the stove via the remote control.
• Switch o the remote control and switch it on again if one wants to restart the stove.
Mechanical stove block
The following conditions may cause the mechanical stove block:
• Structure overheating (“A03”)
• Smoke overheating (“A04”)
• During stove operation air has entered the combustion chamber or there is an obstruction
in the chimney ue (“A05”)
The block is signalled on the display and with a sound signal. In this situation the shutdown stage is activated automatically.When this
procedure is started, any test operation to restore the system is useless. The display signals the cause of the blockage.
SOLUTIONS:
If“A03”appears: the structure is too hot because the product has been used for too long at the maximum power or there is poor ventilation.
When the product is suciently cold, press button B on the control panel or OFF on the remote control to cancel alarm A03. Once the
alarm is cancelled, the product can be switched on normally.
If“A04”appears: The stove switches o automatically. Let the stove cool down for a few minutes and then switch it on again. Check the
smoke expulsion and verify the type of pellet used according to the instructions found in Chap. 2 of this manual.
If “A05” appears: the door has been left open for too long or a signicant amount of air has entered (e.g. missing smoke fan inspection
cap). If these causes are excluded, check and if necessary clean the smoke duct and ue. (it is recommended that this operation is carried
out by an MCZ qualied technician.
The product can be switched on again only after having eliminated the cause permanently.

16-RECOMMENDATIONS FOR SAFE USE
Technical Dept. - All rights reserved - Reproduction is prohibited
ONLY CORRECT INSTALLATION AND APPROPRIATE MAINTENANCE AND CLEANING OF THE APPLIANCE CAN GUARANTEE
CORRECT OPERATION AND SAFE USE OF THE PRODUCT.
We would like to inform you that we are aware of cases of malfunctioning of domestic pellet-fuelled heating products, mainly due to
incorrect installation and use, as well as inadequate maintenance.
We would like to assure you that all of our products are extremely safe and certied according to European standards of reference. The
ignition system has been tested with the utmost attention to enhance ignition eciency and to prevent any type of problem, even in the
worst operating conditions. In any case, like for any other pellet-fuelled product, our appliances must be installed correctly and undergo
regular periodical cleaning and maintenance to guarantee safe operation. Our studies show us that malfunctioning is mainly due to the
combination of part or all of the following factors:
• Brazier holes obstructed or brazier deformed, due to lack of maintenance and conditions which can cause delayed ignitions,
generating an anomalous production of unburned gases.
• Insucient combustion air due to a reduced or clogged air inlet duct.
• Use of smoke ducts nonconforming to regulatory installation requirements, failing to guarantee an adequate draught.
• Partially clogged chimney, due to lack of maintenance, reducing the draught and making ignition dicult.
• End chimneypot nonconforming to the indications of the instruction manual, and therefore not suitable to prevent potential inverse
draught.
• This factor is crucial when the product is installed in especially windy areas, such as costal regions.
The combination of one or more of these factors could generate important malfunctioning conditions.
To keep this from occurring, it is fundamental to guarantee that the product is installed in compliance with standards in force.
Furthermore it is of the utmost importance to respect the following simple rules:
• Every time the brazier is removed for cleaning, it must always be put back properly in the work position before using the product,
completely removing any residual lth left on the support base.
• Pellets must never be loaded in the brazier manually, either before ignition or during operation.
• The accumulation of unburned pellets ensuing a failed ignition must be removed before repeating ignition. Also check that they are
fed correctly and that the combustion air inlet/smoke outlet are regular.
• If ignition fails repeatedly, immediately suspend use of the product and contact a qualied technician to check its operation.
Compliance with these indications is absolutely sucient to guarantee proper operation and to avoid any type of problems with the
product.
If the above-mentioned precautions are not taken, and during ignition the brazier is overloaded with pellets thus generating anomalous
smoke in the combustion chamber, carefully follow the indications below:
• Do not disconnect electrical power to the product for any reason whatsoever: this would stop the smoke extractor, releasing smoke
into the environment.
• Take the precaution of opening the windows to ventilate the installation room from any smoke in the environment (the chimney
might not work properly).
• Do not open the re door: this would compromise regular operation of the smoke extraction system to the chimney.
• Just switch the stove o by acting on the on-o button on the control panel (not the rear power supply socket button!) and move
away until smoke has completely evacuated.
• Before attempting re-ignition, clean the brazier and its air passage holes completely of all deposits and unburned pellets. Put
the brazier back in place, removing any residue from its support base. If ignition fails repeatedly, immediately suspend use of the
product and contact a qualied technician to check its operation and the chimney.

17-CLEANING
Only by properly servicing and cleaning the product is it possible to ensure its safety and correct operation.
ATTENTION!
All the cleaning operations of all parts must be performed with the product completely cold and the plug
disconnected.
Disconnect the product from the 230V power supply before performing any maintenance operation.
The product requires little maintenance if used with certied good quality pellets.
DAILY OR WEEKLY CLEANING PERFORMED BY THE USER
Brazier cleaning
Before ignition, always clean the “T” brazier and remove any ash or incrustation from it that might obstruct the air ow holes, paying
attention to hot ash. In the case of ignition failure, or if fuel in the tank runs out, unburned pellets may accumulate in the brazier. Always
empty the residue in the brazier before each start-up. You may only use a vacuum cleaner to remove ash when it is completely
cold. In this case, use a suitable vacuum cleaner to remove small sized particles.
