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 BS 5854:1980 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 either a prefabricated block chimney in accordance with Building Regulations Approved Document J or a twin walled insulated stainless steel flue to BS EN 1856 can be used. These chimneys must be fitted in accordance with the manufacturer’s instructions and Building Regulations.

A single wall metal fluepipe is suitable for connecting the stove to the chimney but is not suitable for using for 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 fireboxes 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 either an adjustable flue damper or alternatively a draught stabiliser should be fitted. The adjustable flue damper should not close off the flue entirely but should in its closed position leave a minimum continuous opening free area of at least 20 % of the total cross sectional area of the flue or fluepipe.

Adequate provision e.g. easily accessible soot door or access doors, must be provided for sweeping the chimney and connecting fluepipe, also to permit visual checks on the integrity of the flue when the appliance is serviced.

English

H07024510 / DT2000575 - Rev. 00

Hearth

he 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 always 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 wooden floor, 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 should be an adequate air supply into the room in which the stove is installed to provide combustion air. This is particularly necessary if the room is double-glazed or a flue draught stabiliser is operating in the same room as the appliance. It may be necessary to increase the air vent size in property with low air permeability [≤ 5.0 m

/(h.m2)] The provision of air supply to the stove must be in accordance with current Building RegulationsApproved Document J. An opening window is not appropriate for this purpose.

Connection to chimney

All the stoves have a rear and/or top flue gas connector that allows connection to either a masonry chimney or a prefabricated factory made insulated metal chimney in accordance with the instructions for the appliance given in the instruction booklet.

Commissioning and handover

Ensure loose parts are fitted in accordance with the instructions given in the instruction booklet.

On completion of the installation allow a suitable period of time for any fire cement and mortar to dry out, when a small fire may be lit and checked to ensure the smoke and fumes are taken from the stove up the chimney and emitted safely to atmosphere. Do not run at full output for at least 24 hours.

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 with the fuels likely to be used on the stove and warn them to use only the recommended fuels 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 6539 in the presence of children, aged and/or infirm persons. Make provision for securing a suitable guard where applicable.

Carbon Monoxide Alarm

A carbon monoxide alarm complying with BS EN 50291 must be fitted in the same room as the appliance in accordance with the current Building Regulations Part J. It should be positioned on the ceiling at least 300mm from any wall or, if it is located on a wall, as high up as possible (above any doors and windows) but not within 150mm of the ceiling. The alarm should also be between 1m and 3m horizontally from the appliance.

SUPPLEMENTARY USER OPERATING INSTRUCTIONS

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 room

(b) Let the fire out or eject and safely dispose of fuel from the appliance

(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 flueway 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 in the installation instructions 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.

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.

If the fire is left unattended a spark guard to BS3248, specification for spark guards for use with solid fuel appliances should be used.

Chimney cleaning

The chimney should be swept at least once a year for smokeless fuels and a minimum of twice a year for wood and other fuels. 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 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.

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.

READ THE INSTRUCTION BOOKLET AND THESE INSTRUCTIONS CAREFULLY

BEFORE USING THE STOVE

English

H07024510 / DT2000575 - Rev. 00

Extractor fan

here 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 the air control setting to the minimum, and tightly close the doors of the stove. This should cause the chimney fire to go out in which case the control should be kept at the minimum setting until the fire in the stove has gone out. The chimney and flueways should then be cleaned. If the chimney fire does not go out when the above action is taken then the fire brigade should be called immediately.

After a chimney fire the chimney should be carefully examined for any damage. Expert advice should be sought if necessary

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.

HETAS Ltd Approval Please note that HETAS Approval only covers the use of wood on the stove and approval does not cover the use of other fuels either alone or mixed with other fuels, nor does it cover instructions for the use of other fuels.

USER OPERATING INSTRUCTIONS - WOOD

The instructions detailed in the section / in the instruction booklet should be followed.

Door operation

Describe door operation and use of the tool to open and close the doors, if appropriate.

Lighting of fire

Place some firelighters or paper and dry kindling wood on the grate and cover with a small amount of fuel. Set air controls to maximum and set light to firelighters or paper. Close the doors and allow fire to burn until fuel is well alight then load with more fuel and adjust air controls to the required level of heat output.

Before relighting the fire clean the firebed of excess ash and clinker and empty the ashpan.

Refuelling

To ensure trouble-free operation the stove/firebox must have the necessary air available for combustion and this is provided through the permanent air vent.

The permanent air vent 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

educe the minimum recommended section;

- be in a position whereby it cannot be obstructed.

The airflow necessary for the fire may be obtained in different ways:

- through a permanent air vent direct into the room of installation;

- with ducting through pipes direct to the room of installation,

increasing the recommended minimum free cross section by at least 15%;

- from an adjacent room to the place of installation provided this air

flows freely through permanent apertures communicating with the outside.

If the appliance is being fitted within an existing firebox recess, specialist advice should be sought before fitting any permanent ventilation within this area.

The adjacent room from which air is taken must not have a low pressure compared to the exterior due to a counter draught caused by the presence in that room of another appliance in use or of a suction device. The permanent apertures in the adjacent room must comply with the requirements given above.

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.

The air supply must comply with the current copy of the Building Regulations Approved Document J.

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.

he room where the appliance is to be installed must comply with the following requirements:

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

They must not be in a vacuum in relation to the outside environment due to the effect of contrary draught caused by the presence i

n the room where the firebox is installed of another appliance or an extractor device.

Do not use two stoves, a firebox and a stove, a stove and a wood-fired cooking range, etc. in the same environment, since the draught of one could affect the draught of the other.

• Recirculation type cooker 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 stove or firebox must not be fitted where there are 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 stove or firebox 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.

T2010171-00

1.6 CAPACITY LOAD 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 stove (given in the paragraph “TECHNICAL DATA”). If the floor has an unsuitable load-bearing capacity, take adequate countermeasures.

T2010130-01

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: a) 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, …

b) 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”).

Rated power being equal, products with the Multi-fire system can evenly distribute heat throughout the rooms to be heated.

1.8 METHOD OF HEAT DIFFUSION

Diffusion with the Multifuoco System

An original Piazzetta system designed to distribute heat evenly throughout the environment, even for several rooms on different f

loors.

The Multifuoco System

is very simple to install. It is necessary to install the ventilation kit, following the instructions given with the same, before positioning the stove and installing the surround. A

fter having installed the ventilation kit, it is necessary to connect the warm air outlets to the fan using 75mm diameter hoses. The warm air outflow may be sent in a maximum of four directions using two “Y-elements”. It is advisable to install closable warm air outlets and only one of these may be installed at a distance of less than six metres from the stove, keeping the remaining outlets closed so that distribution may be adjusted as required.

With the Multifuoco System

the KNOCKOUTS on the rear of the stove must NOT BE REMOVED, otherwise the apertures must be covered over with a metal plate sealed with silicone resistant to high temperatures and fixed with self-drilling screws. (Figure 16 - 17)

Under no circumstances must collars and any knockouts on the upper part of the stove (see figure 14) be obstructed in order to allow proper operation of the Multifuoco System®and the regular outflow of the warm air that stratifies inside the internal hood and comes out the hood grilles. For the size of the hood grille, see the “TECHNICAL DATA” paragraph under “Minimum section of duct for convective air with open inlet and outlet”.

The warm air ducts must be in non-flammable, resilient and if possible smooth material. To decrease heat loss the pipes must be suitably lagged with insulating material.

For best installation of the Multifuoco System®, Piazzetta supplies as optionals: Inlet/Outlet with closure; Wall Inlet/Outlet with closure; Suction Inlet/Outlet with fan; Hose; Y element; Connecting bend; Hose clamp. See the area dealer for other available accessories.

Diffusion by natural convection

For the stove to work by natural convection the knockouts on the rear (Figure 16 - 17) must be opened during installation in order to allow the warm air to flow upwards and out. There must be apertures or grilles located underneath the grate (see figure 15) with “Minimum section of duct for convective air with open inlet and outlet” that cannot be closed and are at least the size indicated in the “TECHNICAL DATA” paragraph. A passage for air must be made in the top part of the surround so that the heat may flow out from the internal hood through the hood grilles. For the hood grille size, see the “TECHNICAL DATA” paragraph. The air may be ducted in this mode to adjacent rooms.

Use the rear collars on the stove for warm air ductwork and leave the front ones for normal outflow by natural convection towards the hood grille. If all the collars are to be used for air d

uctwork, a hood grille must be installed in any case for the

normal outflow of stratified warm air.

Warm air outlet grille heat radiation area

A safety area must be ensured around the warm air outlet grille, within which there must be no flammable objects (furniture, carpets, curtains...). The safety area includes 600mm from the outer edge of the grille. Figure 18

1.10 MINIMUM SAFETY DISTANCES

Ceiling

Floor

Danger area for radiation

- FLAMMABLE WALLS: the stove may be installed near flammable

alls provided suitable protection consisting of insulating and noncombustible material is inserted. To insulate the stove and to install the surround correctly, construct a lining wall in non-flammable material (e.g. fireresistant plasterboard or masterboard) and insert a “C” thick layer of i

nsulating material between the two walls. Always leave a gap “A” between the stove and the lining wall. (Fig. 19 - 20)

- NON-FLAMMABLE WALLS: always leave a gap of 5 cm between the stove and the lining wall.

- FLAMMABLE CEILING: create an 8 cm false ceiling of nonflammable material. The minimum distance between the false ceiling and connection to the flueway must be 20 cm, while the flue connection must be insulated with at least 3 cm thick non-flammable material that is resistant to high temperatures. (Fig. 19 - 20) If the surround canopy and the flue connection are metal, the minimum distance from the false ceiling may be reduced to 10 cm, but the insulation of the connection to the flueway must be at least 6 cm thick.

- NON-FLAMMABLE CEILING: the minimum distance between the ceiling and connection to the flueway must be 20 cm.

If the floor is made of flammable material, it must be protected with a layer of insulating material of thickness “E” while an air space “D” must be left between the firebox and the floor. (Fig. 19)

For insulation, use insulating material with the characteristics given in the paragraph “SUITABLE HEAT INSULATING MATERIALS”.

There is a radiation area in front of the stove which must be kept free of any flammable element, such as: carpets, curtains, wood furnishings, ornaments, flammable liquids, fire-lighting products or firewood, etc. This area is defined by the distance “R”. (Fig. 19 - 20)

Failure to comply with the above could cause a fire!!!

1.11 CONNECTION TO THE FLUEWAY

Connection to the flueway must be done using pipes as short as possible without narrowing or restrictions and with a maximum slope of 45° from the vertical..

Flexible metal or asbestos-cement pipes must not be used

Pipes and bends or elbows must be made in compliance with current r

egulations

WARNINGS WITH REGARD TO FLAMMABLE WALLS OR CEILING:

If the connection has to go through elements or walls in heatsensitive flammable materials, create a layer of at least 20 cm insulation around the pipe. (Fig. 21)

After having drilled a hole in the wall to insert the pipe through into the flueway, the air gaps must be filled with non-flammable, resilient materials with a reduced capacity of heat transmission (e.g. lightweight concrete). Fig. 22

Check that the connection to the flueway is gas/smoke-tight, since the appliance operates in a vacuum.

It is recommended that the connector pipes be insulated with insulating material having the characteristics given in the paragraph “SUITABLE HEAT INSULATING MATERIALS”.

Check that the pipe does not penetrate too far into the flueway, thereby choking the pipe for the passage of smoke and combustion gases.

H07024510 / DT2000575 - Rev. 00

DT2010177-00

1.13 HOOD GRILLE

The hood grille has the function of allowing air to pass from inside the hood to the environment or vice versa if the Multifuoco system is installed. W

arm air comes out of the hood grille with the natural convection system and it is therefore necessary to maintain the safety distances from flammable materials such as: flammable ceilings or walls, ledges/beams, furniture, curtains, etc.. The hood grille must be installed at least 50cm from the ceiling and with at least 30cm safety d

istance to the sides.

For the hood grille size, see the “TECHNICAL DATA” paragraph.

A non-closable hood grille must be installed without connecting it to the stove so that the warm air that has stratified inside the lining wall can flow out.

With a ceiling over 3 metres high, a NON-CLOSABLE hood grille must be installed on the hood lining at a height of 30cm from the ceiling to allow the stratified air to flow out.

DT2010626-00

2.1 DESCRIPTION OF THE APPLIANCE

The firebox is an excellent solution because of its core. The firebox is made entirely in thick gauge steel. It comes ready for use without needing any laborious assembly work. It ensures high heating efficiency, reduced consumption and safe use. H

eat is diffused by: radiation, conduction, natural convection or forced convection with application of the Multifuoco System, which is an exclusive ventilation system for quickly and evenly distributing heat at floor level that has been created by the Piazzetta R&D Department. All the firebox are fitted with a metal hood that wraps around and covers the firebox canopy and allows a greater recovery of heated air. By connecting hoses to the holes on the metal hood, heated air may be distributed by natural convection also to adjacent rooms. With the Multifuoco System, the air is taken up from the grille located on the canopy backplate, it enters the metal hood and upon passing t

hrough special gaps is distributed by forced convection through the outlets located in the lower part of the cladding or distributed to adjacent

rooms through relative ducts. (See paragraph “METHODS OF HEAT DIFFUSION”).

3.0 PREPARATION FOR INSTALLING

DT2010326-00

- Carefully read all the information contained in the section “GENERAL RULES” before installing the firebox.

- Unpack the firebox.

- Release the counterweight by slackening the relative screw to be found inside the upper part of the door (Fig. 27 and 28).

- Release the grate by unscrewing the wing nut (Fig. 29), remove the wood shims and the metal section to be found under the grate and then replace the grate.

- Where present, remove the polystyrene parts fixing the two smoke baffle plates to the inside of the firebox.

- Fit the “Multifuoco System®” ventilation kit, if required, following the sequence given in the respective instructions and refer to the paragraph “METHODS OF HEAT DIFFUSION”.

- Adjust the height of the grate, adjusting the feet of the hearth in relation to the chosen surround and making the hearth level. The firebox is provided with feet allowing the height of the grate to be raised 25 cm above the ground (Fig. 30). If this height needs to be increased, insert suitable shims.

- Fit the smoke damper (see “INSTALLATION OF SMOKE DAMPER”).

- Connect the firebox to the flue as indicated in “CONNECTION TO THE FLUE”.

- Light for the first time and check that the firebox is working properly (see “LIGHTING FOR THE FIRST TIME”).

- If the check is successful, proceed with installation of the surround.

4.0 INSTALLATION OF THE SMOKE DAMPER

DT2010328-00

The hearth is provided with a smoke damper with articulated rod which aligns with the angle of inclination to which the damper is being set. For installation purposes proceed as follows:

- Position the damper [2] in its seat and keep it in a vertical position.

- Insert the rod [1] fully into the damper [2]. During this operation, the tongue [3] remains facing downwards. (Fig. 31)

- Proceed with the installation of the smoke outlet pipe and its c

onnection to the flue as indicated in the section with the same

name.

- Construct or finish the preparation of the lining and of the facing wall.

- Insert the wooden plug provided into the box [4] and thread it onto the rod [1].

- Then determine the exact position of the box which must follow the angle of the facing wall. By moving the box with the plug, the rod [1] remains as a guide and it will thus be possible to determine the ideal position of the box, rod and facing wall.

- Cut off the rod [1] at 1 cm inside the outer face of the wall.

- Thread on the plate [5] and screw it to the box [4].

- Fit the handle [6], ensuring that the position of the damper corresponds to that of the plate.

If the facing wall is of fire resistant plasterboard (Fig. 33), the box [4] is secured to the wall by screwing on the plate [5] after turning up the side edges.

* Approximate values.

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 classification is according to the heat yield of the wood, the longest flame time it provides, its composition 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 stove 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 firebox.

- Another characteristic of softwood is that it gives a lively but shortlived 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.

Under no circumstances use liquid fuel of any kind whatsoever.

All these materials or similar ones could be hazardous for the user, damage the firebox, the flue connection and the flue, and, last but not least, pollute the environment.

5.0 USE

DT2010329-00

T2010043-00

5.1 FUEL

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

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 c

are and take all necessary precautions. When you need to add wood to the firebox or to adjust the air flow, use the glove or the hand protector provided. If the door of the product fails to close automatically, operation with the firebox open will only be possible with constant checking of the flame.

Log size

The size of the wood logs can also affect the efficiency of the product. It is essential for the wood to be arranged on the grate on top of a l

ayer 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 34. We therefore recommend using logs of the following size:

perimeter approx. 30/35 cm;

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

Under no circumstances use liquid fuel of any kind whatsoever. All these materials or similar ones could be hazardous for the user, damage the firebox, the flue connection and the flue, and, last but not least, pollute the environment

5.2 SMOKE DAMPER REGULATION

(*) Position referred to a draught of 12 Pa

When lighting the firebox, put the damper to the open “APERTO” position until a bed of embers has been formed. Once the firebox is properly lit, put the damper to the operating position, which 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.

Before putting in any logs, always set the damper to the open “APERTO” position. After having put in the wood, set the damper back to the functioning position.

.3 COMBUSTION AIR REGULATION

The rated thermal efficiency is determined with the air damper. Pay attention to the positions given in the table below according to the fuels being used. T

he positions given below refer to rated efficiency. Since efficiency also depends on atmospheric and climatic conditions and therefore on the draught, the most suitable position will be found with experience. Regulation is carried out as shown in figure. R

eference should also be made to the paragraph “SMOKE DAMPER

REGULATION”.

Regulation and quantity of material to be burned for rated power:

DT2010045-03

5.4 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 drawer and remove any elements of carriage used to protect any part of the stove. 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 door of the stove;

• close the combustion air dampers (MINIMUM position) only on appliances with combustion air damper;

• let the fire go out slowly;

• open all doors and windows to ventilate the room;

• do not remain in the room or re-enter until you are sure it is safe to do so;

• check the cause of malfunctioning.

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

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.

- Keep the air dampers in the operating position (except for lighting), see paragraph “COMBUSTION AIR REGULATION”.

- 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.

Fig. 36

DT2030526-00

Data obtained in a laboratory qualified to issue certification.

Should the flue have a strong draught exceding 12 [Pa], the smoke damper must be moved towards the closed “CHIUSO” position.

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.

H07024510 / DT2000575 - Rev. 00

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 air or smoke damper to the open position (MAXIMUM) (see paragraphs “COMBUSTION AIR REGULATION” or “SMOKE

AMPER REGULATION”). Fig. 37 Fig. 38

- 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. To light the soft wood quickly, open the door by approx. two centimetres for 5–10 minutes. Figure 38

- Once the bed of embers has been created, stoke-up with the recommended amounts of fuel. Keep the door closed except when adding more fuel and adjust the combustion air or the smoke damper as instructed in the respective paragraphs “COMBUSTION AIR REGULATION” or “SMOKE DAMPER REGULATION”.

DT2010047-00

5.7 NIGHT TIME OPERATION AT MINIMUM

After normal operation during the day, the appliance may continue to operate for a few hours at night. When stoking up the fire for the last time in the evening, ensure that the bed of embers is sufficient, put the wood in the grate and then set the combustion air dampers to minimum. Night time operation of the stove at minimum depends on the type of wood (a very hard wood is recommended), the flue draught and the weather. The amount of wood to put on and the necessary adjustment of combustion air flow will be learned with experience (see the paragraph “COMBUSTION AIR REGULATION”). The next morning, start up the fire at maximum to burn off any creosote formed during the night. Creosote deposits start to form when the flue temperature falls to below 150 °C. To prevent this from happening it is important to try to maintain the grate of the appliance at normal working temperature (rated heating efficiency phase) as long as possible.

Prolonged operation of the stove at minimum could require more frequent cleaning of the grate and the flue.

5.6 OPENING THE DOOR

The door must remain closed while the stove is alight, otherwise it could damage the inside of the stove. The door must be opened slowly, holding it slightly ajar for a moment before opening it completely. Open the door when the flame has died down and certainly never when the flame is very intense.

Always use the hexagonal door handle tool provided.

Do not slam the door shut otherwise the glass could break.

5.8 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 and the primary air damper be set fully open so that the wood burns faster and thereby stabilises the draught.

T2010051-00

5.9 OVERHEATING AND EXTINGUISHING

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

- immediately stop the supply of fuel;

do not open the stove door;

- close the air dampers (MINIMUM position);

The fire will go out due to lack of air.

When the appliance has cooled down, find the cause of the problem and if necessary call in specialised personnel.

In the event of fire, extinguish with a fire extinguisher.

Do not extinguish the fire with water.

Air the room well before using it again in order to get rid of any smoke and combustion gases.

H07024510 / DT2000575 - Rev. 00

6.0 MAINTENANCE

DT2010111-02

T2010058-00

6.1 PERIODIC CHECKS

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 o

peration, 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 flueways (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, deflectors, smoke dampers, etc);

- the ventilation system (apertures, air ducts, grilles) if installed. Check that the automatic door closing system and the air dampers 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.

T2010059-03

6.2 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.

DT2010060-00

6.3 CLEANING THE STEEL PARTS

The steel sections of the cladding should be cleaned with a soft, dry cloth before applying any detergents. Afterwards it is recommended that you use a degreasing agent such as acetone or vinegar diluted in water.

DT2010061-03

6.4 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.

All maintenance work (cleaning, any replacements, etc.) must be carried out when the firebox is shutdown and cold. Do not use materials that could scratch or damage the glass, since scratches could become cracks. Under no circumstances use abrasive substances.

T2010057-02

English

H07024510 / DT2000575 - Rev. 00

DT2010700-00

6.5 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 stove. T

he 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.

Only for the purpose of cleaning the glass, the hinged-type door may b

e opened using the door handle tool provided in the kit. Insert the door handle tool into the relative hole in the door and turn to open

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. This can only be broken by heavy impact, such as banging the door too hard. In the event of breakage replace with original Gruppo Piazzetta S.p.A. parts only. Do not operate the appliance if the glass is broked or cracked.

Seal control

Proper tightness of the door seal is essential for optimal product performance. It is therefore recommended that the seals be checked periodically or after a long period of use for signs of wear or damage. If necessary replace them using Gruppo Piazzetta S.p.A. original spare parts.

Fig. 40

T2031079-00

T2010049-04

6.7 DISPOSAL OF ASHES

Ash from natural (non-treated) wood burned in stoves or open fireboxes 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 10m2annually.

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 nonorganic material are not present.

T2010063-00

6.6 CLEANING THE GRATE AND THE ASH TRAY

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.

DT2010064-00

6.8 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 stove 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.

H07024510 / DT2000575 - Rev. 00

DT2010334-00

6.9 REMOVING THE SMOKE BAFFLE PLATES

The appliance is fitted with two smoke bafle plates, which are designed to lengthen the path of the flue gas or smoke by increasing the heat exchange surface area. The smoke baffle plates rest on s

upports inside the fireboxes, as shown in figure 41-42. Should it be necessary to replace the smoke baffle plates, unscrew the hexagon nut (for the fireboxes 650HT and 655HT only) to be found on the left part of the smoke baffle plates, push the smoke baffle plates upwards, turn them downwards and remove them.

6.10 CLEANING THE FAN (ONCE A YEAR)

All cleaning and maintenance operations must be carried out after DISCONNECTION OF THE POWER.

Pursuant to current regulations on the safety of electrical equipment, you must contact a Piazzetta After-Sales Service Centre or a qualified electrician for all and any work connected with installation, maintenance or servicing that involves access to electrical parts.

Dust can accumulate in the ventilation kit and in particular in the holes of the protective cover of the fan, the grilles and the fan blade, which should therefore be cleaned once a year. Use a vacuum cleaner or compressed air, being careful with the electrical parts. The ventilation kit must be disassembled for proper cleaning. Follow the installation procedure in the reverse order (see the instructions enclosed in the kit).

DT2010068-00

6.11 SHUTTING DOWN

Before any long period during which the firebox 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 checkup as outlined in the paragraph headed “PERIODIC CHECKS”.

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.

DT2010379-01

6.12 CLOSING DOOR SYSTEM

This operation should be carried out by specialised personnel.

The “rise n’fall” door closing system must be checked periodically, at least once every two years; attention must be paid in particular to lubricating the roller located inside the double glazing or, depending on the model, the pulleys located outside the double glazing.

English

H07024510 / DT2000575 - Rev. 00

Some of the above problems could be resolved by following the instructions. Only qualified persons must carry out work on the stove and only when it is cold and disconnected from the power supply (pull out the plug). Unauthorised tampering with the appliance or use of other than original spare parts invalidates the warranty and relieves the m

anufacturer of all and any liability. The manufacturer shall not be liable for any problems caused by lack of or inefficient maintenance or by failure to comply with the instructions in the product installation and operating guide.
