This stove operates only and exclusively with

pellets (pressed wood sawdust). Top quality pel-

lets without impurities should be used.

In order to obtain a constant flame with a pleas-

ing appearance it is important to use 6 mm di-

ameter pellets that are about 20 mm long, and

as regular as possible.

The stove needs a flue gas exhaust pipe of 80

mm diameter and a combustion air inlet pipe of

40 mm diameter.

Where possible, we recommend installing a T-pipe for inspection at the stove exhaust gas

outlet, in order to recover the burnt microdust, and also a steel pipe two metres high, to

be connected to the existing flue in order to discharge the flue gas.

This device will prevent smoke formation inside the rooms should there be a power failure

for any reason during stove operation.

STANDARD EQUIPMENT:

• User’s and installation handbook.

• Remote control.

OPTIONAL EQUIPMENT:

• Wall smoke flue with quick closure.

• External digital thermostat for the room.

• Room thermostat included in the stove.

• GSM telephone modem (to allow control of the stove from a remote location).

IMPORTANT INFORMATION REGARDING SAFETY

PREPARATIONS FOR INSTALLATION

• In order to prevent the possibility of fire, make sure that the apparatus is installed cor-

rectly by carefully following the instructions of this handbook.

• Do not place the stove in rooms where curtains, carpets or other furnishings could

burn due to the heat generated by the stove.

• Do not position the stove near curtains, inflammable or combustible material.

• When installing the stove, make sure that is properly connected to an earth point using

the (green-yellow) electric cable.

• The plug for connection to the main power supply must be accessible when the stove

is installed.

IMPORTANT INFORMATION

FOR THE USER

Fuel used

• This apparatus has been built to burn only 6 mm di-

ameter pellets (pressed wood). It is very important to

choose a clean, top-quality pellet without impurities.

For the stove to work properly and safely it is necessary to

use pellets that comply with the following standards: DIN

51731 and ONORM-M 7135 (thermal value, residual humidity, diameter, quality of wood used...).

Ecowood cannot assume liability for poor operation of the stove if poor quality pellets

are used.

• Use only pellets and never put other inflammable or combustible material in the stove.

• Do not use the stove as an incinerator or for any purpose other than that for which it

was intended.

• Do not use liquid fuel.

• Keep your stock of pellets at least one metre away from the stove.

Important instructions before ignition

• Make sure that the hopper door (pellet tank) is

closed when the stove is in operation.

• Make sure that the fireplace and ash box doors

are properly closed.

• Before lighting the stove make sure that all mov-

ing parts have been assembled correctly in their

respective positions.

PRETTY - NICE - LADY

DIT

• The gas output system works by negative pressure in the combustion chamber, there-

fore slight positive pressure is formed in the flue gas exhaust pipe; for this reason it is

very important to ensure that the exhaust pipe is free of blockages and fully sealed

until it is outside the building.

• To ensure good combustion, make sure that the exhaust pipe and also the combustion

air input pipe are clean.

• It must be possible for all stages of the flues to be inspected and removed so that inte-

rior cleaning can be carried out.

Recommendations

for using the stove correctly

• Make sure that the combustion crucible is

always clean; if necessary, remove it when it

is cold and clean the holes with a metal

scraper, empty the dust from the tray con-

taining the crucible. This operation guaran-

tees a good combustion.

• Clean the combustion chamber every day before lighting the stove and remove any ash

residues deposited on the crucible and walls.

• Clean the glass only when it is cold, so as to prevent the risk of burns or scalds, or

breakage or cracking of the glass itself.

Use special products for cleaning glass and the body work.

• Take care not to knock against the stove as this could cause permanent damage.

• If the glass is cracked or broken do not attempt to light the stove.

• Do not open the door of the hearth when the stove is lit.

• Always follow these instructions precisely when lighting the stove.

• We advise you not to leave the stove unattended while it is operating.

• When the stove is not working, you are advised to unplug it from the mains.

• Do not perform any unauthorised modifications on the appliance.

• Only use spare parts recommended by the manufacturer.

How to proceed when lighting the stove for the first time

For the first few hours of operation the stove will give off an odour caused by stabilisa-

tion of the paint and protective grease; to lessen the discomfort, air the rooms well.

Advice

For the first few hours of operation, the gasket on the door of the hearth may stick to the

stove. If this happens, remove the seal from the stove, dust it with ash (it acts as an excellent

anti-adherent coating) and insert it in its position in the door without using any type of adhesive.

PRETTY - NICE - LADY

INSTALLATION

The stove must be installed by qualified personnel, who must diligently follow all

the rules for correct installation, respecting all the relevant technical, legal and

safety standards in force at the time.

When positioning the stove respect the

distances shown in the drawing on the

right.

Place the stove away from curtains, fabrics,

ornaments or anything else that may

cause fire.

If the stove is positioned near a wood-lined wall or the gas exhaust pipe is in contact with

similar material, insulate the material with suitable fireproof or fire-resistant products.

Connect the flue pipe of your stove to an existing

chimney or, alternatively, install a fume exhaust

pipe outside the building. The pipe must have a

minimum pipe diameter of 80 mm and reach

higher than the top of the roof.

If the stove is installed in a building with poten-

tially inflammable walls, it will be necessary to

place an insulating sleeve between the wall and

the flue gas exhaust pipe and similarly for the

overhanging part of the building’s roof.

A T-pipe for inspection should always be installed

between the flue gas outlet on the stove and the

flue itself.

DIT

If the gas exhaust pipe is installed as in the draw-

ing on the right, a rain protection cover will be

needed in addition to the requirements listed

above.

If the stove is to be installed in an existing chim-

ney flue built into the wall, the pipe should be

installed along the whole length of the chimney

flue in order to prevent condensation that would

mark the walls.

COMBUSTION AIR INLET:

In order to guarantee good combustion, the stove must receive enough air to ensure the

fuel receives sufficient oxygen. Connect the combustion air inlet to the outside so that it

cannot be obstructed, even partially, in any way. If the stove cannot be connected directly to

the outside, it is possible to install a permanent ventilation grating: this will guarantee

perfect combustion (and hence lower pellet consumption with less ash accumulating in the

hearth) and will prevent health risks for those using in the room.

Between the stove and the floor, if the latter could be inflammable, be sure to insert heat

protection, ensuring it protrudes at the front and sides by at least 20 cm.

Connect the power supply cable to a 230 volt mains outlet.

Make sure that the body work of the stove is earthed correctly.

NOTE: it is possible to change the direc-

tion of the flue gas outlet, (standard, on

the back inside the stove) so that the

outlet can be on the left side, looking at

the stove from the front. To take advan-

tage of this possibility it is necessary to

disassemble and turn the flue exhauster

motor screw through 90°, tighten the

screws in the new position and make an

90 mm hole on the desired side.

This modification must be done only and exclusively by the installer.

Is not possible to change the direction of the flue gas outlet on the stove with majolica

covering (NICE CER)

OPERATION

• After installing the stove as described above, fill the tank on top of the stove with the

pellets through the door on the stove. The tank should always contain enough fuel to

guarantee a regular supply to the stove and the door should be closed during operation.

• Make sure that the crucible is correctly inserted into the tray.

If the crucible is not inserted properly or is very dirty it may cause poor combustion

or the fire may not ignite.

• Make sure that the hearth door and the ash collection drawer are closed properly so

that smoke does not escape, moreover, excessive air infiltration will increase smoke

production and deposit more dirt in the hearth and on the glass.

• During the ignition stage (25 minutes), the pellet loading rate is that setted by the manufac-

turer and cannot be changed.

PRETTY - NICE - LADY

DIT

• The hot air fan comes on automatically about 15 minutes after ignition, at the first

speed, and levels itself at the selected power for the normal operating cycle, 25 minutes

after ignition.

• It is possible to adjust the hot air fan separately from fuel loading rate (only for the first

two power levels); the two functions are currently set proportionately by the manu-

facturer.

• To switch off the stove completely just press the ON/OFF button again; after the flame

has gone out the stove will remain in operation for about 25 minutes until all the inter-

nal parts have cooled down.

IMPORTANT

Continuous operation of the stove at maximum power could shorten the life of the electronic and

mechanical components, and also reduce safety.

The stove is able to operate continuously for long periods of 10÷15 hours if the selected pellet

loading power level does not exceed the third position.

Using the stove at the fourth or fifth loading rate for long periods will reduce safety, therefore an

automatic power limiting device has been installed as standard in the stove.

If the automatic power limiting device is disabled at the user’s request (this should be done

by the installer technician following an evaluation of the conditions under which the stove

is to be used), it is necessary to connect the stove to the flue gas exhaust system using

stainless steel pipes, or pipes painted with airtight seals. If the fourth power level is se-

lected we advise operating the stove continuously at this level only if it is alternated

hourly with operation at lower load rates, while the fifth level should only be used con-

tinuously for a maximum of 30 minutes.

REAR AIR DISCHARGE FUNCTION

(LADY model excluded)

To use rear air discharge, take into account the following

recommendations:

When the stove is used with a closed butterfly valve, the

power selector should not be set higher than third

speed to avoid overheating, causing the heat safety switch

to activate. The switch can be found to the right, at the rear

inside the stove.

If this happens, the user must wait until the stove cools

down to a temperature less than 93°C so as to be able to

reactivate and ignite the stove again.

MAINTENANCE

Warning! Before carrying any maintenance, disconnect the power supply and wait

for the stove to cool down completely.

ORDINARy MAINTENANCE:

Weekly, by the user

• When the stove is not ignited and cold, remove and

vacuum clean the ashes from the recovery tray.

• Check the hearth and clean the holes if necessary,

making sure that all the holes are open.

• Clean any ash residues from the hearth holder,

from the combustion air pipe and from the igni-

tion resistance.

• Clean the combustion chamber and the glass with

non-abrasive products.

ExTRAORDINARy MAINTENANCE:

every 2500 working hours, this must be done by a professional technician

Front cleaning:

• Remove the exchanger and make sure that the flue gas exhaust ducts between the

exchanger and exhaust box are not obstructed by ash, and clean as necessary.

Rear cleaning:

• Remove the panel fastened down with four screws and clean it carefully, using a vacuum

cleaner to suck out the dust deposited inside the exhaust flue and the ash box.

• Take out the flue exhauster motor and clean the screw carefully.

• Re-assemble all the parts in the reverse order, oiling the screws.

• After carefully carrying out all necessary checks, the automatic stove operation block-

ing device should be reset so that the stove will operate for a further 2500 hours.

The advice about regular cleaning and maintenance is only indicative and may vary according

to the quality of the pellets used in the stove, therefore whenever you note worsening

combustion or increased dirt on the fireplace and glass surface this cleaning should be car-

ried out in any case.

We recommend taking out an annual maintenance contract with the place where you

bought the stove. In this way you will be able to programme cleaning of the stove at the end

of the season, keep it in working order and ensure it is ready to operate properly the fol-

lowing season.

DIT

WARNING

Installation and extraordinary maintenance must be done only by skilled, technical personnel.

• IMPORTANT NOTE: if the stove is connected to the outside by a metal flue gas ex-

haust pipe, two conditions could be deleterious to good combustion.

1- If the horizontal part of the flue gas exhaust pipe is too long, this will worsen the quality

of combustion and noticeably increase ash residues in the grate. For this reason the

electronics board has a facility for regulating both the exhaust pressure and pellet loading

rate. This should be carried out only by the installer technician, at installation or when

conditions make it necessary.

2- A vertical metal exhaust pipe that is three / four metres long will increase the combus-

tion rate. This will cause the stove to go out at the minimum power level. To prevent this

just increase the selected power level or change the original settings.

MAINTENANCE OF THE SMOKE ExHAUST DUCT

• Annually, we recommend cleaning the smoke exhaust duct in order to prevent self-

combustion of any soot and powder that may be deposited there.

• In case of fire switch off the stove immediately and disconnect it from the power supply.

PRETTY - NICE - LADY

OPERATING PROBLEMS AND SOLUTIONS

Warning! Only skilled technical personnel are allowed to dismantle the stove and

work on the internal components.

Before carrying out any operation whatsoever, disconnect the power supply and wait

until the stove has completely cooled down.

1. If the stove does not ignite, make sure that:

• It is connected to the electricity supply.

• The crucible is inserted into its holder.

• The ash collection box is inserted into its holder.

• The door of the hearth is closed.

• Pellets arrive in the crucible; make sure the tank contains sufficient fuel for the stove to

operate. If the pellet supply finishes during use, the stove will switch off by itself.

• The thermal safety switch is activated; otherwise disconnect the power supply, reset the

switch by pressing the button on the switch itself, then restore the power supply.

• The combustion air pipe is completely open.

• The exhaust gas flue allows the fumes to escape. If not this would fail to generate the

necessary negative pressure and the vacuum pressure switch would interrupt the power

supply to the pellet loading motor.

• The flue exhauster motor works properly. If it is not working, make sure that it is pow-

ered; if there is power and it turns slowly, replace it with a new one (if the flue exhauster

motor stops, the electronic board will immediately stop to feeding the pellet).

• The screw motor is working properly.

If it is not working, make sure that it is powered; if there is power and it does not turn,

replace it with a new one (if the motor reducer stops, the stove will use up the fuel in

the crucible and then go out completely).

• The hot air fan is working properly. If it is not working, make sure that it is powered; if there is

power and it does not turn, replace it with a new one (if for any reason the fan does not work,

the stove will stop automatically, to avoid overheating by activating the temperature cutout).

• The resistance is red-hot.

If it is not working, make sure that it is powered; if there is power and it does not heat

up, replace it with a new one.

• The pellet feed screw is not obstructed by a foreign body (remove fuel from tank)

• The vacuum pressure switch has not been blocked by poor combustion or an obstruction

in the exhaust pipe (re-activate it by blowing and sucking until you hear the switch come

into operation).

• Check whether the stove is ready for programmed cleaning after 2500 hours have ex-

pired. The display will show Cleaning/Maintenance message.

If the problem persists, consult your retailer.

PRETTY - NICE - LADY

DIT

2. If the stove goes out during operation:

• Check all the possibilities in previous section.

• Check whether the stove is ready for programmed cleaning after 2500 hours have ex-

pired. The display will show Cleaning/Maintenance message.

• Make sure that the thermal safety switch (re-settable manually), on the inside back right

of the stove, has been reset.

Remark: on all LADY models the switch is located underneath the stove left-hand side.

• Before resetting the switch find the reason for its triggering.

Note that the thermal switch can only be reset with electrical supply off and when the stove

temperature has fallen below 93°C.

POWER FAILURE

Brief power failure: if there is a brief power failure (60 seconds), when the stove is at the

ignition stage or is operating normally, the stove is programmed to re-ignite itself. If the

power failure lasts for a longer, indefinite period, when the power returns the stove will go

into an extinguishing cycle, setting up for the next (manual or programmed) ignition. In this

case the display will show Black-Out message.

To reset the stove functions, switch it ON-OFF.

Temporary power failure: If there is a power failure lasting 3÷5 minutes, with direct flue

gas exhaust pipes the stove may emit some smoke into the room, produced by the unburnt

pellets present in the grate.

This does not constitute a safety risk. The problem can be avoided by installing the exhaust

pipe as shown on this handbook.

Electrical safety: the stove is protected against power surges by two fuses on the elec-

tronics board.

Clock not programmed

Problem: The time and date has not been set.

The timers cannot be used.

Solution: Set the time and date and any timers in the

respective menu.

Maintenance request for cleaning

Problem: There are 100 operating hours left from the time of the message

appearing before the stove will be blocked for cleaning.

Solution: Arrange for a technician to clean the stove.
