HEALTH AND SAFETY PRECAUTIONS

Special care must be taken when installing the stove such that the requirements of the Health and Safety at Work Act are met.

Handling

Adequate facilities must be available for loading, unloading and site handling.

Fire Cement

Some types of fire cement are caustic and should not be allowed to come into contact with the skin. In case of contact wash immediately with plenty of water.

Asbestos

This stove contains no asbestos. If there is a possibility of disturbing any asbestos in the course of installation then please

READ THE INSTRUCTION BOOKLET AND THESE SUPPLEMENTARY INSTRUC-

TIONS CAREFULLY BEFORE INSTALLATION

These instructions together with those in the instruction booklet cover the basic principles to ensure the satisfactory installation of the stove, although detail may need slight modification to suit particular local site conditions. In all cases the installation must comply with current Building Regulations, Local Authority Byelaws and other specifications or regulations as they affect the installation of the stove. It should be noted that the Building Regulations requirements may be met by adopting the relevant recommendations given in British Standards BS 8303, BS EN 15287-1:2007 as an alternative means to achieve an equivalent level of performance to that obtained following the guidance given in Approved Document J.

Please note that it is a legal requirement under England and Wales Building Regulations that the installation of the stove is either carried out under Local Authority Building Control approval or is installed by a Competent Person registered with a Government approved Competent Persons Scheme. HETAS Ltd operate such a Scheme and a listing of their Registered Competent Persons can be found on their website at www.hetas.co.uk.

CO Alarms:-

Building regulations require that when ever a new or replacement fixed solid fuel or wood/ biomass appliance is installed in a dwelling a carbon monoxide alarm must be fitted in the same room as the appliance. Further guidance on the installation of the carbon monoxide alarm is available in BS EN 50292:2002 and from the alarm manufacturer’s instructions. Provision of an alarm must not be considered a substitute for either installing the appliance correctly or ensuring regular servicing and maintenance of the appliance and chimney system.

M360 Firebox Installation Instructions February 2015

seek specialist guidance and use appropriate protective equipment.

Metal Parts

When installing or servicing this stove care should be taken to avoid the possibility of personal injury.

STOVE PERFORMANCE

Please refer to the table in the main instruction manual for details of the stoves’ performances

PREPARATORY WORK AND SAFETY CHECKS

IMPORTANT WARNING

This stove must not be installed into a chimney that serves any other heating appliance.

There must not be an extractor fan fitted in the same room as the stove as this can cause the stove to emit fumes into the room.

Chimney

In order for the stove to perform satisfactorily the chimney height must be sufficient to ensure an adequate draught of approximately 15 Pa so as to clear the products of combustion and prevent smoke problems into the room.

NOTE: A chimney height of not less than 4.5 metres measured vertically from the outlet of the stove to the top of the chimney should be satisfactory. Alternatively the calculation procedure given in EN 13384-1 may be used as the basis for deciding whether a particular chimney design will provide sufficient draught.

The outlet from the chimney should be above the roof of the building in accordance with the provisions of Building Regulations Approved Document J.

If installation is into an existing chimney then it must be sound and have no cracks or other faults which might allow fumes into the house. Older properties, especially, may have chimney faults or the cross section may be too large i.e. more than 230 mm x 230 mm. Remedial action should be taken, if required, seeking expert advice, if necessary. If it is found necessary to line the chimney then a flue liner suitable for solid fuel must be used in accordance with Building Regulations Approved Document J.

Any existing chimney must be clear of obstruction and have been swept clean immediately before installation of the stove. If the stove is fitted in place of an open fire then the chimney should be swept one month after installation to clear any soot falls which may have occurred due to the difference in combustion between the stove and the open fire.

If there is no existing chimney then any new system must be to the designation described above and in accordance with Building Regulations Approved Document J.

A single wall metal fluepipe is suitable for connecting the stove to the chimney but is not suitable for use as the complete chimney. The chimney and connecting fluepipe must have a minimum diameter of 150 mm and its dimension should be not less than the size of the outlet socket of the stove.

Any bend in the chimney or connecting fluepipe should not exceed 45°. 90° bends should not be used.

Combustible material should not be located where the heat dissipating through the walls of fireplaces or flues could ignite it. Therefore when installing the stove in the presence of combustible materials due account must be taken of the guidance on the separation of combustible material given in Building Regulations Approved Document J and also in these stove instructions.

If it is found that there is excessive draught in the chimney then a draught stabiliser should be fitted. Fitting of a draught stabiliser will affect the requirement for the permanent air supply into the room in which the stove is fitted in accordance with Approved Document J (see also combustion air supply).

M360 Firebox Installation Instructions February 2015

Adequate provision e.g. easily accessible soot door or doors must be provided for sweeping the chimney and connecting fluepipe where it is not intended for the chimney to be swept through the appliance.

Hearth

The hearth should be able to accommodate the weight of the stove and its chimney if the chimney is not independently supported. The weight of the stove is indicated in the brochure.

The stove should preferably be installed on a non-combustible hearth of a size and construction that is in accordance with the provisions of the current Building Regulations Approved Document J.

The clearance distances to combustible material beneath, surrounding or upon the hearth and walls adjacent to the hearth should comply with the guidance on the separation of combustible material given in Building Regulations Approved Document J and also in these stove instructions.

If the stove is to be installed on a combustible floor surface, it must be covered with a non-combustible material at least 12mm thick, in accordance with Building Regulations Approved Document J, to a distance of 30 cm in front of the stove and 15 cm to each side measuring from the door of the combustion chamber.

Combustion air supply

In order for the stove to perform efficiently and safely there must be an adequate air supply into the room in which the stove is installed to provide combustion air. The provision of air supply to the stove must be in accordance with current Building Regulations Approved Document J. An opening window is not appropriate for this purpose.

Connection to chimney

Stoves may have a choice of either a rear or top flue gas connector that allows connection to either a masonry chimney or a prefabricated factory made insulated metal chimney in accordance with their instructions. In some cases it may be necessary to fit an adaptor to increase the diameter of the flue to the minimum required 150 mm section of the chimney or liner.

Commissioning and handover

Ensure all parts are fitted in accordance with the instructions.

On completion of the installation allow a suitable period of time for any fire cement and mortar to dry out, before lighting the stove. Once the stove is under fire check all seals for soundness and check that the flue is functioning correctly and that all products of combustion are vented safely to atmosphere via the chimney terminal.

On completion of the installation and commissioning ensure that the operating instructions for the stove are left with the customer. Ensure to advise the customer on the correct use of the appliance and warn them to use only the recommended fuel for the stove.

Advise the user what to do should smoke or fumes be emitted from the stove. The customer should be warned to use a fireguard to BS 8423:2002 (Replaces BS 6539) in the presence of children, aged and/or infirm persons.

USER MANUAL FOR STOVES WITHOUT BOILERS

SUPPLEMENTARY OPERATING INSTRUCTIONS FOR THE UK MARKET

M360 Firebox Installation Instructions February 2015

TO BE READ IN CONJUNCTION WITH THOSE IN THE INSTRUCTION BOOKLET

WARNING NOTE

Properly installed, operated and maintained this stove will not emit fumes into the dwelling. Occasional fumes from de‑ashing and re‑fuelling may occur. However, persistent fume emission is potentially dangerous and must not be tolerated. If fume emission does persist, then the following immediate action should be taken:‑

(a) Open doors and windows to ventilate the room and then leave the premises.

(b) Let the fire go out.

(d) Do not attempt to relight the fire until the cause of the fume emission has been identified and corrected.

If necessary seek expert advice.

The most common cause of fume emission is flue way or chimney blockage. For your own safety these must be kept clean at all times.

IMPORTANT NOTES

General

Before lighting the stove check with the installer that the installation work and commissioning checks described above have been carried out correctly and that the chimney has been swept clean, is sound and free from any obstructions. As part of the stoves’ commissioning and handover the installer should have shown you how to operate the stove correctly.

CO Alarm

Your installer should have fitted a CO alarm in the same room as the appliance. If the alarm sounds unexpectedly, follow the instructions given under “Warning Note” above.

Use of fireguard

When using the stove in situations where children, aged and/or infirm persons are present a fireguard must be used to prevent accidental contact with the stove. The fireguard should be manufactured in accordance with BS 8423:2002 (Replaces BS 6539).

Chimney cleaning

The chimney should be swept at least twice a year. It is important that the flue connection and chimney are swept prior to lighting up after a prolonged shutdown period.

If the stove is fitted in place of an open fire then the chimney will require sweeping after a month of continuous operation. This is a precaution to ensure that any “softer” deposits left from the open fire usage have not been loosened by the higher flue temperatures generated by the closed stove.

In situations where it is not possible to sweep through the stove the installer will have provided alternative means, such as a soot door. After sweeping the chimney the stove flue outlet and the flue pipe connecting the stove to the chimney must be cleaned with a flue brush.

Periods of Prolonged Non-Use

READ THE INSTRUCTION BOOK AND THESE INSTRUCTIONS

CAREFULLY BEFORE USING THE STOVE

M360 Firebox Installation Instructions February 2015

If the stove is to be left unused for a prolonged period of time then it should be given a thorough clean to remove ash and unburned fuel residues. To enable a good flow of air through the appliance to reduce condensation and subsequent damage, leave the air controls fully open.

Extractor fan

There must not be an extractor fan fitted in the same room as the stove as this can cause the stove to emit smoke and fumes into the room.

Aerosol sprays

Do not use an aerosol spray on or near the stove when it is alight.

Use of operating tools

Always use the operating tools provided when handling parts likely to be hot when the stove is in use.

Chimney Fires

If the chimney is thoroughly and regularly swept, chimney fires should not occur. However, if a chimney fire does occur turn off the stove immediately and isolate the mains electricity supply (if applicable), and tightly close the doors of the stove. This should cause the chimney fire to go out. If the chimney fire does not go out when the above action is taken then the fire brigade should be called immediately. Do not relight the stove until the chimney and flue ways have been cleaned and examined by a professional.

Permanent air vent

The stove requires a permanent and adequate air supply in order for it to operate safely and efficiently. In accordance with current Building Regulations the installer may have fitted a permanent air supply vent into the room in which the stove is installed to provide combustion air. This air vent should not under any circumstances be shut off or sealed.

USER OPERATING INSTRUCTIONS

Please read the important notices given above before referring to the main instruction book for detailed operating instructions.

Recommended fuels

Stoves may be designed to burn dry seasoned wood logs and/or solid mineral fuel as indicated in the main stove manuals.

HETAS Ltd Approval

HETAS approval may be limited to specific fuel types as detailed in the main instruction manuals. Approval does not cover the use of other fuels either alone or mixed with the recommended fuel, nor does it cover instructions for the use of other fuels.

M360 Firebox Installation Instructions February 2015

1.1 SINGLE CHIMNEY OR FLUE WAY

Every appliance must have a vertical flue pipe operating by natural draught to discharge

the combustion gases outdoors. The flue must:

comply with regulations in force in the place of installation of the appliance;

be tight to the products of combustion, waterproof, suitably insulated, made with

materials resistant to the corrosion of the gases and to stress;

be connected to just one fireplace, fireplace or extraction hood (Fig.2);

be properly sized, with constant free internal section, equal to or greater than the

diameter of the flue pipe of the fireplace and at least 3.5 m in length (Fig.2);

be mainly in a vertical position with a deflection from the axis of no more than 45° (Fig.

2);

be at a suitable distance from combustible or flammable materials, ensured by an air gap

or suitable insulating material (Fig.3);

be of uniform internal section, preferably round. Square or rectangular sections must

have rounded corners with a radius of at least 20 mm and a maximum ratio between the

sides of 1.5 (Fig. 3-4-5);

the walls must be smooth if possible and without narrowing; bends must be regular and

without discontinuity (Fig.6).

It is forbidden to make fixed or mobile apertures on the flue pipe to connect

appliances other than the one to which it is already connected.

It is forbidden to pass other air ducts or service pipes inside the flue pipe, however

large it is.

If the flue pipe is an incorrect size or installed other than in compliance with the

above instructions, Gruppo Piazzetta S.p.A. cannot be held liable for malfunctioning

of the product, damage to property or injury to persons or animals.

1.2 SOOT INSPECTION

We recommend that the flue must have a chamber for collecting solid matter and any condensate located below the connection and which may be easily inspected by means of an airtight door. (Fig. 1)

M360 Firebox Installation Instructions February 2015

1.3 CHIMNEY STACK

The chimney stack must comply with the following requirements:

it must have an internal section and shape the same as the flue (A);

it must have a useful outlet section (B) of not less than twice that of the flue (A);

the part of the chimney that emerges from the roof or remains in contact with

the outside (e.g. in the case of a flat roof), must be cove red with brick or tile

elements and in any case well insulated;

It must be built in such a way as to prevent the penetration of rain, snow and

foreign matter into the flue and to ensure that in the event of winds from all

directions and angle, discharge of the combustio n products is assured

(chimney stack with down-draught cowl).

Recommended distances for correct chimney operation.

To ensure trouble-free operation of the chimney and allow correct dilution of the

products of combustion in the air, the chimney stack must be installed at the

distances given below:

6-8 metres from any buildings or other obstacles that are higher than the chimney

stack;

50 centimetres higher than any obstacles located at a distance less than 5 me-

tres;

outside the reflux area. The size and shape of this area differ according to the

angle of inclination of the roof and it is therefore necessary to adopt the minimum

heights shown below.

M360 Firebox Installation Instructions February 2015

1.4 FRESH AIR INTAKE

To ensure trouble-free operation the fireplace must have the necessary air

available for combustion and can be provided through a fresh air intake.

The fresh air intake must:

have a total free cross section at least equal to the size given in the paragraph

"TECHNICAL DATA";

be protected by a grille or suitable guard provided it does not reduce the

minimum recommended section;

be in a position whereby it cannot be obstructed;

The airflow necessary for the fire may be obtained in this ways: through a fresh air intake direct into the room of installation.

with ducting through pipes direct to the installation room, going under the floor. Also

increase the recommended minimum free cross section by at least 15%; (Fig. 12)

Combustion air must not be taken from adjacent rooms used as a garage or a

combustible materials store or for activities posing a fire hazard.

1.5 INSTALLATION ENVIRONMENT

The appliance should be installed in a location which allows safe and convenient use as well as easy maintenance. If the product being installed requires

an electrical socket, the room must also be provided with an earthed power supply in accordance with current regulations. The room where the appliance

is to be installed must comply with the following requirements.

It can not be used as a garage, store for combustible material or for activities with a risk of fire.

It can not be in a vacuum in relation to the outside environment due to the effect of contrary draught caused by the presence in the room

where the fireplace is installed of another appliance or an extractor device.

Do not use two stoves, a fireplace and a stove, a fireplace and a wood-fired cooking range, etc. in the same environment, since the draught

of one could affect the draught of the other.

Devices suitable for cooking food with relative hoods without an extractor fan may only be used in kitchens. Gas appliances of type C are allowed (refer to current legislation and regulations in the place of installation)

Gas appliances of type B are not allowed (refer to current legislation and regulations in the place of installation).

The fireplace must not be used simultaneously with collective type ventilation ducts with or without extractor fan, other devices or other

appliances such as: forced ventilation systems or other heating systems using ventilation to change the air. Such systems could cause a

vacuum in the environment of installation even if installed in adjoining or communicating rooms.

The fireplace must not be used: in stairwells except in buildings with no more than two apartments; in corridors for common use; in

bedrooms; in bathrooms or shower-rooms.

1.6 LOAD-BEARING CAPACITY OF THE FLOOR

Check the load-bearing capacity of the floor by adding together: the weight of the protections (lining walls), insulating materials, surround (given in the

surround instruction booklet) and the fireplace (given in the paragraph "TECHNICAL DATA").

If the floor has an unsuitable load-bearing capacity, take adequate countermeasures.

M360 Firebox Installation Instructions February 2015

1.7 HEATING CAPACITY

Check the heating capacity of the appliance by comparing the rated power given in the paragraph "TECHNICAL DATA" with the power required by the environment to be heated. The energy requirement may be calculated approximately by multiplying the square metres of area by the height of the ceiling; the result is then multiplied by a coefficient, which depends on the degree of insulation of the building, that is, on internal and external factors of the dwelling:

Internal factors: type of window and door frames, thickness of the insulation and walls, type of building materials, presence of stairwells, walls with extensive glazing, high ceilings, position of the rooms to be heated in relation to other adjacent heated or unheated rooms,

External factors: geographical position, average outdoor temperature, exposure, wind speed, latitude, altitude, …

Example of approximate calculation of the energy requirement to heat a fixed volume to 18/20° C:

The coefficient that is normally used is determined according to the real conditions as they occur case by case. From 0.04 to 0.05 kW per cubic metre in a well insulated environment From 0.05 to 0.06 kW per cubic metre in a poorly insulated environment

3 rooms measuring 20m2 X (H ceiling) 2.7m = 162 m3 (volume)

In an environment with a good degree of insulation, an average value (coefficient) of 0.045 kW may be taken

162 (volume) X 0.045 (kW) = 7.3 kW necessary (6300 kcal/h)

Conversion 1kW = 860 kcal/h

Consult a heating technician or engineer for a correct check and calculation of the requirement of the environments to be heated (see "REFERENCE STANDARDS").

1.8 SUITABLE HEAT INSULATING MATERIALS

Type of suitable heat insulating materials.

Material: mineral fibre; ceramic fibre; rock wool. Form: sheets; mat; shells. Specifications: specific weight of at least 245 kg/m3 with limit working temperature of at least 1000°C.

Thermal conductivity X (400°C) < 0.1 W/mK Thickness: as shown in the figures in the paragraph "MINIMUM SAFETY DISTANCES".

If the insulating material is not lining the walls, it must be fixed all over the surface of the walls with anchorage points every 30 cm.

Material coded “AGI Q132” or “ DIN 18895” is allowed for heat insulation.

1.9 MINIMUM SAFETY DISTANCES

If the floor around the fireplace is made of flammable material, it must be protected with non-flammable material or be replaced with a floor of nonflammable material. This area may be recognised as follows. (Fig. 13) On the perimeters of the fireplace "A", the floor must be covered for a distance equal to the height "H" + 30 cm and in any case not less than 50 cm.

Example: for surrounds with H = 60 cm, the result is A = 90 cm.

"H = 60 cm" means the height from the floor to the grate.

1.10 PREVENTION OF DOMESTIC FIRES

The product must be installed and used in compliance with the manufacturer's instructions and European and national standards as well as local regulations.

When a flue pipe passes through a wall or a ceiling, special installation methods must be applied (protection, thermal insulation, distances from heat-sensitive materials, etc.).

It is also recommended that all elements made of combustible or inflammable materia l, such as beams, wooden furniture, curtaining, flammable liquids, etc. be kept outside the heat radiation range of the fireplace and at a distance of at least 1m from the heating block. For other information, see the paragraph "MINIMUM SAFETY DISTANCES". The flue pipe, chimney stack, chimne y and fresh air intake must always be free of obstructions, clean and checked periodically, that is, at least twice during the seasonal period from the ligh ting of the fireplace and during its use. When the fireplace has not been used for some time it is ad visable to carry out the checks mentioned above. For further information, consult a chimneysweep. Only use recommended fuels (see paragraph "FUEL").

Description

Figure 18 shows the types of ceiling flanges that can be used for installing

the M360.

The examples are given purely as an indication, solely for the purpose of

identifying the type of ceiling/roof with which the relative flue pipe should

be associated.

Every self-supporting pipe will be sized as required except for solution

number 1 (standard solution).

Ceiling/roof height is given as the height "H" measured along the axis of the hole in line with the ceiling flange contact surface down to the floor. "a" is the angle of the ceiling/roof (see

detail of figure 18). It is fundamentally important that on-site measurements are accurate in order to define the slope of the ceiling/roof in relation to the floor.

M360 Firebox Installation Instructions February 2015

4.0 PREPARING FOR INSTALLING

To avoid accidents or damage to the product, it is recommended complying with the following instructions. Unpacking and installation must be carried out by at least two persons. All handling must be carried out using suitable equipment and in full compliance with current safety regulations and laws. If ropes, belts, chains, etc. are used, ensure that they are suitable for the weight to be unloaded and that they are in good condition.

The actual stove has FOUR hooks [A] on the top for anchoring ropes; these hooks are sized for lifting only, see detail in fig. 22

Move the pack slowly and without interruption to avoid any jolting of ropes, chains, etc. Never loiter within the radius of action of the loading/unloading equipment (lift trucks, cranes, etc.) and ensure that there are no persons or things within the area. Carefully read all the information contained in the section "GENERAL RULES" before installing the fireplace. Unpack the fireplace. Remove the supplied accessories from the firebox as well as the packaging elements used to wedge parts during transportation. After having removed the packaging from the appliance, remove the grid [B], the ash box [C] and lastly the Aluker grate elements [D]. Put all the parts safely in a corner of the room. (Fig. 21)

Take care not to chip or break the Aluker grate elements.

Remove the self-tapping screws anchoring the product to the pallet, see detail below in figure 22. Only lift the base [E] using the lifting eyebolts [A]; having lifted the product, remove the pallet [F].

The product must be lifted using the indicated eyebolts.

Do not hold the product by the glass frames that are still in a lowered position.

Gruppo Piazzetta S.p.A. cannot be held responsible for any possible malfunction, damage to property or injury to persons due to incorrect unpacking, use or installation of the product.

M360 Firebox Installation Instructions February 2015

5.0 INSTALLATION

5.1 CONNECTING THE BASE TO THE MAINS ELECTRICITY SUPPLY

There must be a cable riser [A] under the base plus relative connection to a

wall-mounted control panel in order for the product to be connected to the

mains electricity supply (220V).

By law the system must be properly earthed and fitted with a residual current

circuit breaker.

The control panel must have a double pole switch [B] used to power the control unit [C] and preferably an emergency switch (optional), which may

be activated by a qualified technician only under exceptional circumstances.

(Fig. 23)

It is recommended that a double pole switch be mounted with

warning light that shows whether or not the product is receiving

electrical current.

Install a double pole ON/OFF switch 220V [D] and a key-operated emer-

gency

switch (optional) [E], which allows a qualified technician to by-pass the con-

trol

unit and lower at least one of the glass panels. (Fig. 24)

This procedure is only necessary when the control unit malfunctions due to external overload generated, for example, by lightning.

In this case stop movement of the glass before it reaches the end stop

because the relative sensors are not active and the guide system could be

damaged (see "REPLACING THE CONTROL UNIT ASSEMBLY").

Under normal conditions it is essential to keep the emergency circuit on wires

F7 (white) and F8 (blue) closed, see "WIRING DIAGRAM".

Even if the key-operated switch is not installed, it is essential that the relative

cables as laid as far as the control panel: this set-up will be useful for any

technician needing to make a fast emergency connection.

Make sure that the power cable and the extension cable connecting to the

control buttons, in the final position, do not come into contact with hot parts.

The emergency switch cable must be no longer than 5 m and a

diameter of at least 2.5 mm is recommended.

5.2 FLUE INSTALLATION

The installation described below is for the first type of installation: FLAT REINFORCED CONCRETE AND HOLLOW TILE CEILINGS with standard pipe H=250/300 cm, see "TYPES OF INSTALLATION".

The upper ceiling cover [A] is inserted onto the pipe until it rests on the lower flange. (Fig. 25)

Do not score or scratch the enamel of the pipe or the cover during insertion.

Before installing the product, see "LOAD-BEARING CAPACITY OF THE FLOOR AND INSULATION".

The position of the hole in the ceiling must be calculated on the basis of where the control unit and therefore your product is to be located.

M360 Firebox Installation Instructions February 2015

Prepare a round hole 0 30 cm in the reinforced concrete and hollow tile

ceiling [B] (the ceiling must be no more than 30 cm thick).

Insert the pipe with cover. (Fig. 26)

With a ceiling other than in reinforced concrete and hollow tiles with height between 250/300 cm, as shown to the side (e.g. ceiling in wood, sloping, etc.), see "TYPES OF INSTALLATION".

At least two persons must carry out this work.

Proceed with fastening the upper part of the pipe. The two parts of the split

ring collar [C] are joined together using the screws and washers provided in

the kit. (Fig. 27)

The screws should not be fully tightened, but just enough to support the pipe

temporarily.

Check that the end pipe flange is exactly 224 cm from the ground.

Check that the flange is level and perfectly vertical using a precision spirit

level. (Fig. 28)

Fasten the whole collar assembly using the screws M8x30 [D] and washers

8x24 [E] provided in the kit.

The remaining split ring collar [C] holds the lower part of the pipe firm.

(Fig. 29)

Check the contact between the split ring collar and the ceiling, ensuring there

are no gaps that could cause the whole hood unit to be somewhat loose

when fixing is completed.

M360 Firebox Installation Instructions February 2015

The split ring collars are fixed to the ceiling through plugs inserted into the

relative holes [F]. (Fig. 30)

Make sure that the fastening and the plugs being used satisfy the

requirements of resistance necessary for guaranteeing that the hood and

relative connections are supported.

Where possible it is recommended that the ceiling be strengthened at the

points where the split ring collars will be anchored.

The ceiling should be reinforced if the chosen type of flue outlet means that

the hood is supported by just the lower split ring collar. If this is the case, ask

the customer to have suitable building work carried out that has been

adequately designed and approved by qualified professionals.

Drill holes Ø5mm in line with the 4 holes marked on the upper split ring

collar. The split ring collar and the pipe should be drilled together.

Fully tighten the 4 self-tapping screws M6 [G] provided in the kit. (Fig. 32)

The above steps complete the flue pipe and make it safe so that it is also

self-supporting.

Carefully check that all screws and bolts are tightened properly. The cover [A] can be slid back along the pipe and fixed to the lower split ring collar. Fasten the cover on to the special mounting plates with the self tapping screws 3.5 x13 [B]. (Fig. 31) During this operation, be careful not to scratch the paint.

M360 Firebox Installation Instructions February 2015

5.3 HOOD INSTALLATION

Remove the packaging from the hood.

At least two people must carry out this work.

Place the hood [A] in line with the pipe [B] and put it on top of a support before fastening it. It is possible to choose the angle of rotation of the hood: ask the customer's opinion to decide on the direction of the smoke damper handle in relation to the room. Carefully fit the flange into position, ensuring that the threaded holes are aligned with the respective flared holes in the flange. Wear gloves during this procedure so as not to damage the enamel of the hood or the pipe. (Fig. 33)

The hood is fixed using the six screws TSPEI M5x16 [C] provided in the kit, taking great care in fully tightening them. (Fig. 34)

5.4 POSITIONING THE APPLIANCE

Raise the base [A] towards the hood [B], only using the indicated lifting eyebolts to lift it. (Fig. 35)

The product must be lifted using the indicated eyebolts. Do not hold the product by the glass frames that are still in a lowered position.

Gruppo Piazzetta S.p.A. cannot be held responsible for any possible malfunction, damage to property or injury to persons due to incorrect use or installation of the product.

Remove the two central self-tapping screws [C] located under the hood [B].

Remove the base template [D] connected to the locating template [E]. (Fig. 36)

M360 Firebox Installation Instructions February 2015

Put the base template [D] at the bottom of the base [A] with the folds/ flanges

directed downwards. (Fig. 37)

Insert the plumb line [F] through the hole in the middle of the locating template [E] and adjust it until the weight just touches the base template [D]. (Fig. 38)

The base [A] is centred by grasping its feet and making the tip of the plumb line coincide with the base template [G].

Check that the base [A] is level, if necessary adjusting the feet very slightly. The best height from the ground of the base with fully screwed on feet will be 60 cm. Avoid (except in particular cases) raising it too much from the ground.

The height of the grate from the ground must not be more than 61 cm.

After having positioned the appliance, remove the locating template [E] and the fastened self-tapping screws [H]. (Fig. 39)

Install the smoke baffle plate [I] inside the hood [B] by inserting it vertically and passing it between the internal fins [L]. Turn the baffle plate 90° and place it with the tabs [M] well inserted into the relative slots [N]. (Fig. 40)

Check that the smoke baffle plate [I] is properly fitted to avoid damage to property or injury to persons during product operation.

M360 Firebox Installation Instructions February 2015

Connect the 220V [O] power cable and power the control unit [P]. Enter the maintenance mode (see "USE" and "MAINTENANCE"). (Fig. 41)

Raise one of the two glass panels [Q] slowly until it is near the hood. Stop before it reaches the plate [R] by releasing the button.

There are mechanical parts in movement during this procedure: use the product with care.

If the appliance has been installed correctly the rim of the glass [Q] should remain about 7 mm from the plate [R]. Check that the same distance has been maintained for both glass panels. (Fig. 42) If there is any difference, check that the hood and the base [A] are level and adjust the position of the product to centre it, distributing the margin between glass and plate so that the distances are equal.

If the base is centred in relation to the hood, product operation and performance is at its best and the glass becomes less dirty.

Having checked that the base is centred in relation to the hood, anchor the base to the floor using the brackets [S] and masonry plugs [T], if possible, or spread some silicone under the brackets. (Fig. 43) T he brackets must adhere to the floor, with the appliance firmly screwed onto the brackets.

Carefully refit the Aluker elements [1] into the base, leaving even gaps between them. Where necessary, shim with tape. (Fig. 44)

Take care not to break or chip the grate elements.

Refit the ash box [2] and the grid [3].

Fit the smoke damper handle [U] into place on the hood.

It is recommended that the handle be left inserted in the hood only for a short time so that it does not overheat; having adjusted the smoke damper, remove the handle and put it in a safe place.

Complete the product by cladding it (see CLADDING INSTRUCTIONS BOOKLET).

M360 Firebox Installation Instructions February 2015

5.5 POSITIONING THE EDGING TRIM

Free the cable (A) with the control buttons (B) fastened to it, by cutting the band that secures it to the control unit (C) inside the base.

The control buttons (B) must be installed where the two holes (F) have been made on the edging trim (D). So that they can be inserted and screwed into their relative housings, the buttons must be disconnected from their cable-end connector (E).

Before screwing down the lock nut (G), it is recommended that some thread-locking liquid or a few drops of high-temperature silicone be applied to the thread.

Fully tighten the lock nut (G) on the inside of the edging trim (D). When the buttons (B) have been installed, reconnect them to the cable-end connector (E).

Enter the maintenance mode (see "MAINTENANCE MODE") and lower both glass panels. Fit the edging trim (D) so that the buttons (B) straddle the line where the glass panels meet. It should be remembered that the top of the edging trim must be at a height of 60 cm from the ground (see "DIMENSIONS").

Before finally closing the cladding, check that the cable (A) is not in contact (with glass panels lowered) with any hot or moving parts of the product. If necessary secure the cable to the internal structure of the cladding using simple cable ties.

If a button is inadvertently connected so that it operates the glass panel on the opposite side, invert the connection in the connector (E) so that each button corresponds to the glass panel where it is positioned.

M360 Firebox Installation Instructions February 2015

6.0 USE

Certain basic facts can be all-important for best performance and getting the most out of your appliance. Please find below some basic information intended to be of use with regard to the choice of firewood, the adjustment of the dampers and proper operation of the appliance. During operation, some parts of the appliance (door, handle, dampers, surround) can reach high temperatures. Therefore exercise great care and take all necessary precautions. When you need to add wood to the fireplace, use the glove provided. Opera tion with the glass open will only be possible with constant checking of the flame but we recommen d to not use the fireplace with the glass open.

Keep any combustible product well away from the fireplace/stove when it is lit (minimum distance from the heat radiation area), for example: wooden furniture, curtains, carpets, combustible liquids, etc.

6.1 FUEL

Use well-seasoned and dry wood with less than 20% moisture content. The table below shows how the heating power decreases as the moisture content increases.

* Approxi mat e valu e.

Wood that is ready to burn must have been dried in the open air sheltered

from rain or snow for at least 2 years after having been cut.

The lower the moisture content of the wood the higher its heating power.

Freshly cut wood has 50% less heat value than dry wood.

Burning wood that is too wet means wasting most of the calories for

evaporation of the water contained in it and, in particular, the walls of the combustion chamber and the flue become fouled and encrusted thereby

affecting efficiency.

It is a good rule to purchase timber during the summer (June-July), since woods are cut

down mostly in the autumn and you can therefore be sure that the timber has already

been seasoned for approximately 1 year.

Firewood can be classified in two qualities: "good" and "mediocre or poor". This classifica-

tion is according to the heat yield of the wood, the longest flame time it provides, its com-

position and density.

Good fuels.

Recommended timber comes from the family of broadleaf hardwoods: beech, hornbeam,

oak, false acacia, ash, birch, maple, elm.

All low-resin and close-grained woods (that is hard and heavy timber) are most suitable,

since they provide the fireplace with a steady, continuous flame.

Mediocre or poor fuels

Timber that is not recommended comes from the family of conifers, willow, poplar and

alder. These light soft woods are resinous and therefore create more soot, few embers

and incandescent sparks, while requiring more frequent cleaning of the flue and the fire-

place.

Another characteristic of softwood is that it gives a lively but short-lived flame and the

consumption is higher for the same heat output.

Unsuitable fuels

Never use wet wood, tarred wood or pellets.

It is also best not to use: refuse (rubbish), waste paper; paper briquettes; plywood or

chipboard; fibreboard; packaging materials; painted wood or wood coated with synthetic

material, plastic laminates, cardboard or milk cartons.

Log size

The size o f the wood logs can also affect the efficiency of the product. It is essen-

tial for the wood to be arranged on the grate on top of a layer of embers.

The logs must not touch the aluker or the glass window nor must they be put on top

of each other. Place the wood as shown in the figure 36. We therefore recommend

using logs of the following size: perimeter approx. 30/35 cm;

length approx. 20-25-30 cm according to the type of hearth.

Under no circumstances use liquid fuel of any kind whatsoever. All these materi-

als or similar ones could be hazardous for the user, damage the fireplace, the

flue connection and the flue, and, last but not least, pollute the environment.

M360 Firebox Installation Instructions February 2015

6.2 SMOKE DAMPER REGULATION

The damper has 7 set positions; the damper handle turns in steps.

When lighting the fire, put the smoke damper to "OPEN" (position III) until a bed of

embers has formed.

This position may vary according to the atmospheric conditions, the type of flue and

consequently the draught. You will learn by trial and error which is the best position for

the smoke damper.

Each time the fire is stoked up with wood the smoke damper should be put to

"OPEN" (position III) to avoid any smoke escaping into the room and to ensure fast

and efficient restart of combustion.

When the fire is well lit, move the damper to the operating position: the first positions are

those for maximum efficiency, as shown to the side. This position can vary according to

the weather, the type of flue and therefore the draught. The most suitable position for the

smoke damper will be found with experience.

6.3 PRESET COMBUSTION AIR

The amount of combustion air entering from the top of the glass is calibrated.

The inflowing air [F] passes the plate [D] and reaches the grate [P] where it directly feeds

combustion.

A combustion air gap is formed around the perimeter, which prevents smoke from

reaching the glass [V] and from dirtying it.

6.4 LIGHTING FOR THE FIRST TIME

Before lighting, remove the supplied accessories (see ACCESSORIES AND EQUIPMENT paragraph) and flammable elements from the grate or from the ash tray/pan. If provided in the kit, it is very important to remove the paint spray can, which could explode. There are two important stages when lighting the appliance for the first time: the operating test and start-up.

1. Operating test. Before carrying out the operating test, check that everything has been installed correctly (see section GENERAL RULES). Start with the lighting stage (see paragraph "LIGHTING"). The first load should be reduced by 50% of the normal recommended amount.

Should smoke come out:

do not open the glass; open the smoke dampers (MAXIMUM position); let the fire go out slowly; air the room before staying in it; check the cause of malfunctioning

Do not extinguish the fire with water as this could damage the grate, see

"TROUBLESHOOTING").

2. Start-up.

During this first time of operation it is recommended to use the appliance at minimum

capacity, stoking the grate for at least the first day with only 50% of the logs usually

indicated as normal.

This stage allows all the parts to settle down and fumes caused by paints/varnishes,

greases or oily liquids used in manufacture to disappear.

Air the room well in this initial stage.

This procedure must be carried out with the forced ventilation system turned off.

After this, the appliance will no longer emit odours due to paint evaporation and must

only be stoked up with the indicated nominal amounts.

M360 Firebox Installation Instructions February 2015

6.5 LIGHTING

An excessive increase in fuel and excessive opening of the air/ smoke dampers,

compared to the values given in the table, leads to an increase in appliance heat,

decrease in efficiency and an increase in wood consumption.

When lighting the fire, the grate should be brought quickly to working temperature. If

it is done slowly, condensation will inevitably form and cause blackening of the

grate and the glass

Put the fuel into the grate according to the methods described below:

put the smoke damper to the open position (MAXIMUM) (see paragraph "SMOKE

DAMPER REGULATION");

place the material for kindling (paper, firelighter, etc.) in the centre of the grate and

add small pieces of soft wood (fir) in the form of a pyramid (Fig. 39).

once the bed of embers has been created, stoke-up with the recommended amounts of fuel and adjust the smoke damper as instructed in the respective para-

graph "SMOKE DAMPER REGULATION".

6.6 OPENING THE GLASS (OPERATING MODE)

Open one of the two electrically operated glass panels using the relative button. Each button controls the movement of one glass panel.

OPENING: press the button; the glass starts to lower and when it is near maximum opening it automatically slows down and then stops. The downward movement of the glass may be stopped at any time in an intermediate position by pressing the button again. When the glass panels are stopped in an intermediate position, upon pressing the button again to restart movement, the speed is reduced until one of the two limit switches is reached, when normal speed is resumed.

CLOSING: keep the button pressed down; the glass starts to rise and automatically goes to the closed position, which is confirmed by a double "beep".

The upward movement of the glass may be stopped by releasing the button. The glass will stop moving immediately and the direction of movement will be reversed (emergency reversal).

In the operating mode it is impossible to open both glass panels; one of the two will always remain closed.

With the fire lit, the buttons can reach a temperature that makes it uncomfortable to touch them with bare hands, so it is advisable to have a pair of gloves nearby.

Do not leave the glass panels lowered during normal operation.

OPENING

Press briefly DOWN

Press again STOP

Keep button pressed UP

Release button STOP

CLOSING

6.7 OPERATION UNDER ADVERSE WEATHER CONDITIONS

During the intermediate seasons with adverse weather conditions or when outdoor temperatures are higher, a sudden rise can cause malfunctioning of the

draught, thereby impeding proper smoke discharge. In this case the grate must be loaded with only a little wood.

6.8 OVERHEATING AND EXTINGUISHING

In the event of overheating or if some appliance parts of the flue turn red:

immediately stop the supply of fuel;

do not open the fireplace door;

close the air dampers (MINIMUM position); The fire will go out due to lack of air.

The fire will gradually go out.

When the appliance has cooled down, find the cause of the problem and if necessary call in specialised personnel (C.A.T. - Piazzetta After-Sales Service Centre).

In the event of fire, extinguish with a fire extinguisher. Air the room well before using it again in order to get rid of any smoke and combustion gases.

Do not extinguish the fire with water.

M360 Firebox Installation Instructions February 2015

7.0 MAINTENANCE

In compliance with current safety laws for electrical appliances, it is compulsory to contact a Gruppo Piazzetta After-Sales Service Centre or qualified

personnel for all work involving installation, maintenance or servicing/repair which involves access to the inside of the cladding or the smoke chamber.

Routine maintenance is essential for correct and efficient appliance operation.

If such work is not carried out with the recommended frequency, appliance performance may suffer.

The manufacturer cannot be held responsible for the deterioration or malfunction of the appliance due to poor maintenance.

All maintenance work (cleaning, any replacements, etc.) must be done with the fire out, the appliance completely cold and the power cable disconnected

from the power supply. Once the appliance has been installed and clad, it can only be accessed from above.

Replacement of the glass, the control unit assembly or other elements and the maintenance that the appliance will undergo over a period of time will only

be possible after having removed all the pieces that prevent direct access from above to the necessary part/s.

The recommended frequency for such work can vary according to the frequency of use and the quality of the fuel that is used.

7.1 PERIODIC CONTROL

Check for any formation of creosote in the pipes connecting to the flue and inside the flue during the seasons when the appliance is in operation, inspecting them at least once every two months. The combustion of the wood (especially if moisture content is higher than 30%) produces pitch and other organic vapours that give rise to creosote. The formation of creosote causes fouling, which obstructs the flue and the passage of smoke.

"Creosote" is inflammable and can catch fire, causing serious damage to both the flue and to the structure of the dwelling.

Only use recommended fuels (see "FUEL" paragraph).

If creosote has accumulated, it must be removed to reduce the risk of fire and to improve heat exchange.

The following must be free from obstruction and inspected at least once every two months: the flue ways (connection to the flue, flue pipe, chimney stack); the fresh air intake; the appliance hearth (correct position of the plates, the ash tray, the grate and grid, smoke baffle plates, smoke dampers, etc); the ventilation system (apertures, air ducts, grilles) if installed. Check that the automatic door closing system and the air dampers (if installed) are in proper working order.

Maintenance of all the above heating system must be carried out at least once a year before the season when it will be used. We also recommend periodically checking the whole heating system during the period of operation until the time when it will not be used for several months.

7.2 CLEANING THE CERAMIC CLADDING

The ceramic cladding must first be cleaned with a soft dry cloth before using any detergent (even mild detergent).

Products are available on the market which are suitable for cleaning ceramics as well as concentrated products for cleaning porcelain. These will remove oil,

ink, coffee and wine stains, etc.

Never soak the ceramic cladding or clean it with cold water when it is still hot as the thermal shock could cause it to crack.

7.3 CLEANING THE PAINTED METAL PARTS

When cleaning the painted metal parts of the product use a soft cloth moistened with water.

Never clean metallic parts using alcohol, solvents, petroleum-based products, acetones or other degreasing or abrasive substances.

In the event of such substances being used the manufacturer will not be responsible for any damage caused. Discolouration of metallic parts may be the result of misuse.

7.4 CLEANING THE GLASS (DAILY)

If the appliance is very slow to heat up in the ignition phase due to fuel that isn't completely dry, this is likely to cause a build-up of tar on the glass. This will

eventually burn off when the appliance is operating at full capacity. If the tar is left to build up over a long period it will require more effort to remove.

We therefore recommend that the glass be cleaned daily before lighting the fireplace.

The glass should be cleaned when cold using ammonia-based degreasing agents and not corrosive substances such as solvents.

Do not use any material that could scratch or spoil the glass, as scratches may develop into cracks or breaks.

In case of breakage: every one of our hearths comes with a door fitted with a 4 mm thick pyroceram panel resistant to thermal shock up to 750°C.

In the event of breakage replace with original Gruppo Piazzetta S.p.A. parts only.

M360 Firebox Installation Instructions February 2015

7.5 CLEANING THE ASH TRAY (DAILY)

The grate and the ash tray must be cleaned daily. Using the grate for a whole day contributes to the accumulation of ash or residual combustion products.

If cleaning is not done regularly there will be an excess of residues, which will affect appliance efficiency.

The ash tray also needs emptying regularly, because if it fills up and obstructs the grate grid it will cause appliance malfunction.

7.6 DISPOSAL OF ASHES

Ash from natural (non-treated) wood burned in stoves or open fireplaces is composed mainly of calcium, silicon, potassium and magnesium oxides.

The ashes can therefore be used as a fertiliser for plants or in the garden, albeit not exceeding 2.6 kg per 10 m2 annually.

The ashes should be placed in a metal container with a sealed cover. The sealed container should be placed on a non-combustible surface at a safe distance from combustible materials until the cinders have been completely extinguished.

Only when they have been fully extinguished can the ashes be thrown away with organic waste, assuming that nails or other non-organic material are not present.

7.7 CLEANING ALUKER

The interior of the unit has been constructed from an innovative material called "Aluker"®.

Aluker® is based on substances that are completely non-toxic and is heat-resistant up to 1400°C.

In spite of its considerable strength it is not recommended that you throw large pieces of wood forcefully against the bricks.

Aluker® darkens when the fireplace is first lit but returns to its natural colour gradually as the bricks warm up.

Some advice for optimum use of Aluker® bricks:

don't use water to put out the fire - leave the bricks to cool by themselves;

don't scratch Aluker® bricks with metal objects;

To clean Aluker® bricks use an ordinary brush.

7.8 MAINTENANCE MODE

Keep both control buttons pressed down for at least 10 seconds and then release them. The control unit will give a warning beep that the "maintenance mode" has been activated; this beep is repeated every 30 seconds. Keep pressing the button corresponding to the glass panel to be moved and the glass will start to move at a reduced speed. Whenever the button is released the glass stops moving and when the button is pressed again the glass starts to move in the opposite direction. Lower the other glass panel in the same way.

The two glass panels cannot be lowered simultaneously.

Before returning to the "operating mode" it is advisable to close the glass panels, ensuring they reach their end-of-travel position. Cut off the power supply to the control unit of the appliance for a minimum of 5 seconds; in this way the "operating mode" will be restored (see "OPENING

THE GLASS").

During the "maintenance mode" take great care in moving the glass panels so as not to injure persons or damage property.

7.9 ACCESSING THE INSIDE OF THE PRODUCT

Enter the "maintenance mode" (see "MAINTENANCE MODE"). Lower one of the glass panels (or both) and cut off the power to the product by putting the wall-mounted double pole switch to "OFF". Remove, in the following order: the grid [A], the ash box [B] and the Aluker elements [C]. (Fig. 47) Put them in a safe place in the room, taking care not to damage them. Use a vacuum cleaner to remove the deposits of ash from the grate base so that no residues fall inside the product onto the most sensitive parts (guides, couplings, electronic parts, belts, motors, etc.). Remove the 4 screws [D] and washers [E] securing the base of the grate [F] to the appliance structure; lift the grate base out carefully so as not to hit the cladding. (Fig. 48)

Edges and surfaces of the surrounding cladding should be adequately protected before working on the product.

Remove the grate base bottom shield [G]. The interior of the appliance may now be fully accessed.

When refitting the parts, before tightening the fastening screws, check that the grate base is centred in relation to the glass panels otherwise they could be scratched on the inside during movement.

7.10 REPLACING THE GLASS

Before replacing any damaged glass, identify and remedy the cause of break-

age.

Enter "maintenance mode" (see "MAINTENANCE MODE").

Protect hands with cut-resistant gloves and eyes with goggles against flying

splinters.

Lower the glass panel that is still intact [C] and cut off the electricity supply to

the product. (Fig. 49)

Remove shards or sharp pieces of the damaged glass panel which could be

attached precariously or become easily detached.

Proceed as described under "ACCESSING THE INSIDE OF THE PRODUCT".

Power the control unit again (switch to ON) and re-enter the "maintenance

mode".

Gradually lower the damaged glass panel [B], taking care that in doing so no

pieces of glass become detached and fall with the risk of damaging property or

injuring persons.

Remove dangling or semi-detached parts and gradually break them up

completely.

Bring the top edge of the damaged glass panel to a semi-closed position [A].

M360 Firebox Installation Instructions February 2015

Work to be carried out by at least two persons.

Remove the screw [D] and the washer [E], working from the inside, and rotate the lever [F], which moves the glass panel clamp, so that it no longer presses against the frame. (Fig. 50) Remove the damaged glass, handling it with care.

Dispose of the damaged glass: it is recyclable waste.

Use a vacuum cleaner to thoroughly clean the points where the new glass panel will rest, scraping and removing any residues of gasket that have remained attached to the glass frame. The new glass panel complete with gasket is fitted into place between the glass panel clamp [G] and the frame [H] (Fig. 51). Check that the fitted gaskets do not become separated or overlap each other. The signs on the glass must be towards the top. Rest the side edge of the glass panel on the internal rebate of the collar [I], checking that there is full contact in the points where the glass is supported [L]. (Fig. 52) Reclose the glass clamp [G] gradually tightening the chain by means of the relative lever [F]. When closure is complete, secure the previously removed screw [D].

Ensure that the chain links are properly engaged with the teeth of the glass clamp lever. Any overlapping will prevent locking and could lead to breakage.

7.11 REPLACING THE CONTROL UNIT ASSEMBLY

The control unit assembly must be replaced if there is serious malfunctioning of the electronics or if it no longer works following a current overload due, for example, to lightning. If both glass panels have remained in the closed position, at least one must be opened with the emergency procedure in order to access the interior of the product. Connect the product to a power supply and use the wall-mounted emergency switch [A], proceeding with great care in short bursts to lower the glass. (Fig. 53)

Stop before the glass is fully opened. The sensors that automatically stop glass panel descent are NOT working.

Cut off the power supply to the product. Pull out the Schuko type power plug and disconnect the Minifit connector (see "WIRING DIAGRAM") from the receptacle coming out of the control unit [B]. (Fig. 54) Disconnect the Molex 4-pin connector that is used for connecting the control buttons. Use a screwdriver to remove the 4 screws [C] and washers [D]. (Fig. 55) Take out the control unit [B] complete with support [E] and replace it with the new one. Reconnect all the cables following the steps described above in the reverse order.

Remember to connect the earth (yellow/green earth wire) to one of the fastening screws on the control unit support.

Before refitting all the components and reclosing the appliance, connect to the power supply and switch on to check correct operation both in the "maintenance mode" (see "MAINTENANCE MODE") and the operating mode (see "OPENING THE GLASS").

REPLACING THE FUSE Do not take out the control unit assembly [B] from the appliance in order to replace the fuse; simply cut off the power supply, unscrew the 4 plastic bushings [G] and open the lid [F]. Change the fuse and refit the lid.

7.12 LUBRICATING THE INTERNAL GUIDES

The glass panel frames are supported on the inside by straight guides that require periodic maintenance: the guides must be clean and adequately lubricated. Enter "maintenance mode" (see "MAINTENANCE MODE"). Lower the glass panel (or both) and then cut off the power supply to the product. Proceed as described under "ACCESSING THE INSIDE OF THE PRODUCT". Thoroughly clean and dry the chromed surfaces of the guides. Remove any deposit or encrustation from the contact surface of the guide [A] and from innermost corners. (Fig. 56) Shift the glass support [B] occasionally and clean the parts that are now exposed.

Only if necessary adjust the guide coupling at the end of cleaning (see "ADJUSTING THE COUPLING").

Lubricate the guide [A] by applying an abundant and evenly spread layer of spray grease. Move the glass panel from one end stop to the other to ensure that the protective film is spread evenly over the guide. (Fig. 57) Repeat this procedure if necessary. Do not, however, use the grease to excess: should grease accumulate on the lower parts of the guide, we recommend that all excess be removed. The lubricant has properties of excellent adherence and viscosity, high resistance to temperature and a very low capacity of mixing with dust or ash. It is therefore recommended that you only use the lubricant we supply (optional).

Other unsuitable lubricants could seriously affect correct operation of the rise n' fall system or the frequency of maintenance.

7.13 ADJUSTING THE COUPLING

Using an Allen key if possible, turn clockwise to tighten the coupling on the guide, thereby reducing the play that normal wear can produce. Adjust the coupling by putting it halfway up the guide with the glass panel half open.

The coupling must only be adjusted if absolutely necessary.

Adjust by tightening the screw [A] the minimum necessary and proceeding by steps to check that the glass panel slides properly. Raise the glass panel at operating speed, checking for any slowing down and if there is, loosen the screw [A] slightly.

Avoid over tightening the screw [A] on the coupling, otherwise when the lubrication of the guide is nearly finished the coupling could lock during movement and trigger an alarm state in the control unit.

7.15 SHUTTING DOWN

Before any long period during which the fireplace will be inactive we recommend that you carry out a thorough cleaning, thereby avoiding encrustations

and oxidations which will be difficult to clean later. We also recommend that as a preventative measure you carry out a general check-up as outlined in the paragraph headed

PERIODIC CONTROL

After a period of inactivity problems relating to the expansion of parts or the release of odorous gases may arise. We therefore recommend that upon

restarting the unit you do not immediately run it at full power. Nor should you activate the ventilation system until the odorous gases have dispersed. This

problem can be dealt with by simply airing the room.

7.14 REMOVING THE SMOKE BAFFLE PLATES

The fireplace is fitted inside above the grate with a baffle plate, which has the function of deflecting the route taken by the smoke thereby increasing the heat exchange surface area. The baffle plate rests on the supports that can be seen in the figure. The baffle plate rests on the supports that can be seen in the figure. To remove the baffle plate, push it upwards, tilt it and then draw it out from below.

Proceed with great care to avoid the baffle plate falling on the Aluker grate.

Clean and then replace, following the above procedure in the reverse order.

Make sure that the front support is inserted into the relative notches, see "INSTALLATION".
