2. THEORETICAL NOTIONS FOR THE INSTALLATION

2.1. PELLETS

Black-and-white photo of a pile of small cylindrical pellets or bricks on a surface (no text or symbols visible)

Fuel pellets

Close-up of a textured, rectangular object with granular surface (no visible text or symbols)

The pellet is obtained by processing the sawdust produced during working wood and timber ( dried wood and paint free. The compactness of the material is guaranteed by the lignin which is contained in the wood itself and allows the production of pellets without the 'use of glues or binders.

The market offers different types of pellets with characteristics that vary based on mixtures of wood used. The diameter varies between 6 and 8 mm, with a standard length between 5 and 30 mm. The pellets of good quality has a density ranging from 600 to more than 750 kg / m3 with a water content that is maintained between 5% and 8% of its weight.

In addition to being an environmentally friendly fuel, as you push the limits of wood residues resulting in a cleaner-burning than that produced with fossil fuels, the pellets also have technical advantages. While a good wood has a calorific value of 4.4 kW / kg (15% RH, after 18 months of seasoning), the pellet is 4.9 kW / kg.

To ensure good combustion, and no power problems, it is imperative that the pellets are stored in a dry place, protected from dirt, and the thermo stove is placed in a place where the conditions are the same, not to generate the same type of problems on the power pellets in the tank. The pellet is usually supplied in 15 kg bags, so storage is very handy.

A good quality pellet ensures good combustion lowering harmful emissions into the atmosphere.

If the fuel is poor, the more often cleaning inside the

grate and the combustion chamber will be required.

The main certifications of quality for pellets in the European

market are

DINplus and Ö-Norm M7135; these ensure respect of:

√ Calorific power: 4.9 kW/kg
√ Water content: max 10% of weight
√ Percentage of ashes: max 0,5% of weight
√ Diameter: 5 - 6mm
√ Length: max 30mm

√ Contents: 100% untreated wood, with no added bonding

substances (bark percentage 5% max)

√ Packaging: in sacks made from ecologically compatible or biologically decomposing material

HANKS strongly recommends using certified fuel in its stoves (DINplus e Ö-Norm M7135).

The use of fuel of inferior quality or not conforming to the specification given above compromises the running of your stove and can therefore lead to the termination of the guarantee and of the manufacturer's responsibility for the product.

HANKS pellet stoves run exclusively on pellets with a diameter of 6 mm (only for Italy) and 6-8 mm (European countries) with lengths that go from 5 mm to 30 mm.

2.2. PRECAUTIONS FOR INSTALLATION

IMPORTANT!

Installation and assembly of the stove must be carried out by qualified personnel.

The stove must be installed in a suitable position to allow the normal operations of opening and ordinary maintenance. The site must be:

• capable of providing the environmental conditions for operation
  • equipped with power supply 230V 50 Hz
• capable of taking an adequate system for smoke discharge
  • provided with external ventilation
  • provided with an earth connection complying with CEI

The stove must be connected to a flue pipe or an internal or external vertical duct conforming to current standards UNI 7129 - 7131 9615. The stove must be positioned in such a way that the electrical plug is accessible.

IMPORTANT!

The stove must be connected to a flue pipe or a vertical duct which can discharge the fumes at the highest point of the building. The fumes are however derived from the combustion of wood products, and if they come into contact with or close to walls, they can make dirty marks. Also take care because the fumes are very hot but almost invisible, and can cause burns on contact. The holes for the passage of the smoke pipe and for the intake of air from outside should be made before positioning the stove unit.

2.3. OPERATING ENVIRONMENT

For proper operation, and a uniform distribution of temperature, the stove should be placed in a location with an air flow that guarantees the air needed for combustion of the pellets (should be available approximately 40m^3/h ) according to the installation and the second regulations in the country. The volume of the environment must not be less than 30m^3 . The air must enter through permanent openings on the walls (near the stove) with a minimum of 100 square centimeters. These openings must be made so that they can not be obstructed in any way, and allow

proper airflow. Air can also be taken to ventilate rooms adjacent provided they are equipped with air hose and are not used as a bedroom and bathroom, or where there is no fire hazard such as: garages, sheds, storage of combustible materials, etc., strictly complying with the requirements under current rules. It is absolutely prohibited to installation the stove in bedrooms, bathrooms, and where it is already installed another d heating device without adequate airflow (fireplace, stove, etc..).

Example of pellet stove installation

where the stove is installed , the stow air flow in sufficient quantity as it is the regular combustion equipment and This can be done by means of perma the walls that give the room to be the outside, ventilation ducts or throu collective. Within this scope , the out stove must have an opening minimum protected by a grid inside and outside must also:

• be communicating directly with the environment
  •be protected by a grate, wire mesh

protection, provided it does not reduce the minimum section.

- position in a suitable manner as to prevent it from being obstructed in any way

It is expressly prohibited the placement of the stove in environments

with explosive atmospheres. The floor of the room where the stove will be installed must be sized appropriately to support the weight of the stove itself (which should be considered in addition to the weight of the machine said the same load must be added a maximum of 60 kg for the pellets, and 80 kg for water). When installing, keep a minimum distance from obstacles and not flammable (B) of 25 cm the rear to, lateral (LR) of 25 cm and anterior (C) of 80 cm. In the presence of objects believed to be particularly sensitive such as furniture, curtains, sofas, carpets, etc., greatly increase the distance of the stove from them. In the presence of wooden floor floor-prepare the plan and in accordance with rules in force in the country, on fire prevention.

It is prohibited to connect the air directly to the stove (communicating directly from the outside), to avoid

compromising thermodynamic performance, however it is required that the conditions still guarantee about 50 m^3/h of air replacement, as provided in the current UNI 10683.

2.5. CONNECTION OF SMOKE DISCHARGE PIPE

H > 4 mt. 2 - 3 mt. MAX 3-5 % H > 1,5 mt.

Example of pellet stove installation

When making the hole for the flue pipe it must be taken into account the possible presence of inflammable materials. If the hole has to go through a wood wall or other thermo labile material, the installer MUST use the Industrial insulated pipe (with min thermal conductivity of 0.07 W / m ° K). The same applies if the stove pipe must go vertical or horizontal sections remain near (min.20cm) to a heat-labile wall. The combustion chamber works in depression, so the exhaust duct for the exhaust fumes will be linked to depression when effective chimney as prescribed.

It should always use pipes and fittings with appropriate seals to ensure

air-tightness in order to avoid possible harmful CO fumes into the environment.

All sections of the exhaust duct must be inspectable and removable to allow for periodic cleaning of the interior, which is necessary for the proper functioning of the system (T-piece with inspection). Position the stove strict accordance with all regulatory requirements and attention to highlighted date.

IMPORTANTE!

All changes direction 90 degrees of the flue gas channel must be prepared if possible with the appropriate fittings to "T" with inspection. It is absolutely forbidden to use a

net at the end of the hose as it can cause serious problems for the proper and safe operation of the stove.

In connection do not use the chimney sections of pipe horizontally, but always the same place at an angle of 5^ minimum to rise, possibly avoiding the use of a 90-degree (you can use upto 3), and use preferably 45^ curves. It is recommended to not use a total length of the pipe diameter 80 mm, greater than 6 m in total.

2.6. CONNECTION TO THE CHIMNEY

Check with suitable instruments that there is a minimum draft. of 10 Pa. At the bottom of the chimney inspected for periodic inspections and cleaning, which must be conducted annually.

You must ensure that a chimney is installed according to wind force.

This type of connection, even in case of momentary power failure, ensuring the evacuation of the fumes.

2.9. TROUBLESHOOTING RELATED TO DEFECTS IN THE CHIMNEY FLUE

Of all the meteorological and geographical factors that affect the operation of a flue (rain, fog, snow, altitude above sea level, period of insulation, exposure to the cardinal points, etc.) the wind is certainly the most decisive. In fact, besides the thermal depression caused by the difference in temperature between the inside and the outside the chimney, there is another type of depression (or overpressure): the dynamic pressure induced by the wind. An ascending wind always has the effect of increasing depression and then the draft. A horizontal wind increases depression for

proper installation of the chimney. A descending wind always has the effect of relieving depression, sometimes inverting it. In addition to the direction and force of the wind, the position of the flue and the chimney from the roof of the house and the surrounding landscape is important.

The wind affects the operation of the fireplace also indirectly by creating zones overpressure and depression as well as the outside, but inside the home. In areas directly exposed to the wind (2) can create an internal overpressure which can promote the draft of stoves and fireplaces, but may be countered by external overpressure if the chimney is placed on the side exposed to the wind (1). In contrast, in areas opposite to the direction of the wind (3) can create a dynamic depression that comes into competition with the natural thermal depression developed by the fireplace, but can be compensated (sometimes) by placing the exhaust duct from the side opposite to the direction of the wind (4)

IMPORTANT!

The operation of the pellet stove is noticeably sensitive to the conformation and position of the flue which is adopted. Hazardous conditions can only be overcome by suitable setting-up of the stove carried out by qualified HANKS personnel.

2.10. HYDRAULIC CONNECTION

IMPORTANT!

The connection of the stove to the hydraulic system must be made ONLY by qualified personnel and can perform the installation in "ART" and in compliance with all statutory and regulatory provisions in force and not in the country of installation. If the installation of the stove requires interaction with another existing facility complete with another heater (gas boiler, gas boiler, oil boiler, etc ...), is recommended for more qualified personnel who can then be challenged to answer the Full compliance of the system, per the applicable law, and issuing the certificate. HANKS disclaims any liability for damage to persons or property or in the event of failure or improper operation, if not complied with the above warnings, and issued the necessary certificates of compliance enforcement work in an appropriate manner. It is absolutely necessary that the network is designed properly sized to dispose of all the heat flux produced by the stove to avoid raising the temperature inside the boiler.

3.2. PREPARATION AND UNPACKING

Open the box, unload the stove from the platform with extreme caution, and place the desired location, making sure that it complies with the requirements.

The body, or block should always be handled exclusively by truck in an upright position. You should pay particular attention to the door and its glass to be shielded from shocks that might compromise their integrity.

However, the handling of the products must be done with extreme caution. Unpack the stove near the area where it will be installed.

The materials that make up the package are neither toxic nor harmful, thus do not require special disposal processes. So the storage, disposal or recycling is eventually complete recovery from the end user in accordance with applicable laws.

Do not store the fireplace and coverings without their packaging.

Position the stove, in the correct position that respects faithfully as previously described above, and proceed with the connection to the chimney.

If you connect your stove to a discharge pipe that runs through the back wall (to take in the chimney) pay extreme caution not to force the entrance in any way.

If the flue of the stove is forced or improperly used to lift or placed into position, it will compromise beyond repair, the operation, and GRACE DESIGN is not considered in any way responsible for such a maladroit and/or neglect in the work, so in these conditions any Recovery operations are excluded from warranty.

Connect the heater hoses for not using the over-constrain the stove to allow the plant and the light shifts. The pressure relief valve (C) must always be connected to a drain hose. The pipe must be suitable to withstand the high temperature and pressure.

3.3.2. Filling the water network

To load of the heater, the heater must be equipped with a tap (optional) with a non-return valve (D) in order to manually fill the network you can use the load tap already on the boiler on the stove.

During that operation, the outlet of any air in the system is guaranteed by the present automatic vent under the top. To guarantee that the valve discharges air, it is recommended to loosen the grey tap and leave the red tap locked (refer to fig.).

The filling pressure during cold status should be 1 bar.

If during operation the system pressure drops (due to evaporatic the gas dissolved in water) to values less

than the minimum indicated above, the User shall, acting on the from the load back to the initial value.

For optimal operation of the stove in a operation (hot), the pressure must be 1.5 bar. Do not exceed 2

bar. At the end of the operation always close the filling tap.

3.3.3. Water characteristics

The characteristics of the water for filling the plant, are very im to avoid the deposition of minerals and the creation of deposits the piping within the boiler and heat exchangers. Therefore it is advised to check with your plumber / fitter the following characteristics:

- Hardness of water circulating in the system to remedy any problems and limestone deposits especially in the hot water heat exchanger. (> 25 ° French

- Installing a water softener (if the water hardness is > 25 ° French)

- Fill the system with treated water (demineralized)

Grey plug loosened 1 turn Red plug blocked

Vent valve under the top

• Any set of a circuit condensation.
• Installation of hydraulic shock absorbers to avoid the phenomenon of "water hammer" along the fittings and pipes.

For those with very large systems (with large water content) or who require frequent replenishment of the plants

in the plant to install water softeners, especially because the scale significantly reduce the thermal conductivity!

3.4. KIT WATER PRODUCTION

All thermo stoves are equipped with HANKS kit for the production of hot water characterized by:

• Plate heat exchanger
  • 3-way diverter valve, electric motor-driven
  • Electrical Flow meter
• stainless steel finned pipes and fittings for connecting
• Pressure valve

The kit has the task of heating hot water from the water line of the house. At a time when there is hot water demand by opening a tap, the internal flow-meter commands the diverter valve to convey the hot water contained inside the boiler, to the plate heat exchanger. The hot water temperature will depend on the water temperature inside the heater, with approximation, is calculated by removing 10^ -15°C to the value read on the control panel of the heater (boiler water temperature). For proper lifetime operation of the heat exchanger plates, it is necessary to know the hardness of your water to prevent fouling, and to block the exchange.

3.5. EXAMPLE OF INSTALLATION DIAGRAMS

The diagrams below are merely indicative. For a proper connection, always follow the notes of the plumbing and heating installer with proven experience. The hydraulic system must meet the mandatory regulations of the place, region or state. The installation, testing and certification of operation must be performed only by authorized personnel, with the issue of certification that the work has been completed in a “state of art” performance, attesting the conformity of the work in compliance with laws and regulations. GRACE DESIGN disclaims any responsibility in case of non-compliance to the above, especially in the absence of proof of certification work in a “STATE OF ART” execution.

The STOVE comes equipped with an automatic igniter for lighting the fuel when the stove is in feeding and lig

VACCUM SWITCH

The STOVE has a vacuum switch located behind the left door, fastened to the base. If a low pressure is create firebox by a leak, opening the front door, a blocked flue, or unsealed ash drawer(some model), the vacuum swit sense it and cause the stove to go into a shutdown mode by showing E5.

AUGER AND AUGER MOTOR

The 2 RPM auger motor turns the auger, lifting pellets up the auger tube. The pellets are then dropped down a tube and into

the firepot. The auger motor is controlled by the control board.

PROTECT TEMPERATURE SENSOR TO AVOIDOVERHEATING

A safety temperature switch switches the stove off automatically if it overheats,. After the stove has cooled meanwhile it shows E6. Whether the heating operation is continued or not depends on the remaining ember fire pan. After you remove the Error Code by "Okay button", If re-ignition does not occur when the fuel supply

CAUTION: If overheating has occurred then maintenance or cleaning work must be carried out.

EXHUASTED TEMPERATURE SENSOR FUNCTION AS LOW TEMPERATURE SWITCH OFF

If the stove cools down below a minimum temperature, then the stove will switch off. This switch off car pre-heating is too slow.

5. MAINTENANCE AND CLEANING

ATTENTION!

All cleaning of all parts must be carried out with the stove completely cold and unplugged.

The stove does not need much maintenance if used with certified quality pellets.

5.1. DAILY OR WEEKLY CLEANING PERFORMED BY THE USER

Close-up of a rectangular metal component with a perforated interior (no text or symbols visible)

Example of clean grate

Close-up of a dark rectangular object with a small white hole and granular texture (no text or symbols visible)

Example of dirty grate

Clean the ash F" and any deposits in the brazier that could clog the air passage holes.

In case of pellets running out in the tank or of a failed ignition alarm (E2), there could be unbent pellets in the brazier. Always empty the residue in the brazier before each ignition.

REMEMBER THAT ONLY A CORRECTLY POSITIONED AND CLEAN BRAZIER

CAN GUARANTEE IGNITION AND OPTIMAL OPERATION OF YOUR PELLET PRODUCT. IF IGNITION FAILS (E2), IT IS IMPORTANT TO REMOVE THE PELLETS LEFT IN THE BRAZIER AFTER REPEATING THE IGNITION OPERATION.

For the brazier to be cleaned properly, remove it from its housing completely and thoroughly clean all the holes and the grate on the bottom. If good quality pellets are used, you will normally only need to use a brush to restore the optimal operating conditions of the

component.

5.1.2. Check every 2/3 days

The frequency of cleaning depends on the type of installation/connection to flue pipe (e.g. more frequent with horizontal connection, less frequent with vertical connection), on the number of working hours, level of power and fuel used. Clean and empty the ash tray" being careful with hot ash.

The ash must be completely cold for a vacuum cleaner to be used to rem it. Only use models suited to sucking ashes recommend emptying the ash pa at intervals of no more than 2 or 3 days.

Cleaning the glass

Once the operation is finished, reinsert the ash pan below the grate making sure it is inserted properly.

5.1.3. Cleaning the glass

For cleaning the ceramic glass, the use of a dry brush is recommended, or if it is very dirty, the special spray detergent, applying a small quantity then cleaning with a cloth.

ATTENTION!

Do not use abrasive products and do not spray the cleaning product on the glass of the painted parts or on the gaskets of the fire door (ceramic fiber cord)

5.1.4. Cleaning of stainless steel and satin-finish surfaces

Normally these surfaces do not need to be treated, but if they do, avoid cleaning them with abrasive materials. For surfaces in stainless and satin brushed steel we recommend cleaning with a paper towel or a clean dry cloth moistened with a detergent based on non-ionic surfactants (< 5%). A spray glass cleaner may be used.

5.1.5. Cleaning of painted parts

Do not clean the painted parts with wet rags when the unit is in operation or hot to prevent thermal shock to the paint which may cause it to detach. Do not use abrasive or aggressive products or materials. Clean with damp cotton or paper towels.

The silicon paints used on HANKS products possess technical characteristics that make them resistant to very high temperatures. There is however a physical limit (380°-400°) beyond which the paint begins to fade or (over 450°) to vitrify; it may then flake and detach from the steel surface. If this happens, it means that temperatures have been

ATTENTION: It is advisable to carry out the cleaning of the upper exchanger at the end of the season and possibly by an authorised HANKS technician in order to replace the gasket that is below plug ^ . (fig.16a).

CLEANING THE LOWER COMPARTMENT

Remove the ash drawerG", empty it and using the nozzle of a vacuum cleaner remove any ash and soot that may have built up under the drawerG". Also remove the grate"F" and clean it every 2/3 days as explained in chap. 5.1.

Remove the drawer E", empty it and using the nozzle of a vacuum cleaner remove any ash that may have built up in the housing of the drawerE".

ATTENTION: It is advisable to carry out the cleaning of flower compartment "E" once a week and in any

case according to the fuel consumption. Check the seal of the ceramic fibre gaskets on the plug and replace it if necessary. Check the seal of the door gasket and replace it if necessary. At the end of the season it is necessary to clean the compartment under the grate and the heat exchanger inside it. This general cleaning should be carried out at the end of the season in order to facilitate the general removal of all residues of combustion, without waiting too long,

Close-up of a hand inserting a small electronic component into a perforated metal panel (no visible text or symbols)

because with time and humidity these residues can become compacted.

5.2.2.Shutting the stove down (end of season)

In the period when the stove is out of use it must be disconnected from the electricity mains. For greater safety, especially if there are children around, we recommend removing the power cable from the rear of the stove. (Figure 17)

Before placing the stove in storage, you should remove all pellets from the hopper with a vacuum cleaner with a long extension. If the fuel is

Figure 17 - Disconnect the stove from the electrical mains

left in the hopper, it may get damp, stick together, and be difficult to light at the beginning of the next season. If the stove is removed from its place of installation, MUST be placed in a location that is protected from atmospheric agents. If pressing the main switch (located on the back of the stove) does not make the control panel display light up, it could mean that the service fuse needs replacing.

ATTENTION!

Disconnect the electrical cable.

On the rear of the stove there is a fuse holding compartment which is located underneath the supply socket. With a screwdriver open the cover of the fuse holding compartment, and replace the fuse if necessary (3.15 AT delayed type). Figure 18 Plug the unit back in and press the main switch. If the problem persists or occurs again, contact your MCZ retailer.

5.3. CHECK OF INTERNAL COMPONENTS

ATTENTION!

The check of the internal electromechanical components must be carried out only by qualified personnel with technical knowledge of electricity and combustion. If necessary, contact authorized HANKS retailers.

We recommend that an annual maintenance service is carried out, preferably under a programmed service contract. The essential part of this service is a visual and functional check on the following components:

• Reduction motor
• Smoke expulsion fan
• Smoke sensor
• Heat-exchanger fan
• Ignition sparkplug
• Resettable pellet thermostat
  • Room temperature sensor
• Motherboard / service card
• Fuses protecting panel - motherboard - services card
• Wiring

The following is a summary of the checks and/or maintenance tasks which are indispensable for the correct operation of the stove.

6. PROBLEMS / CAUSES / SOLUTIONS

NOTE: All repairs must be performed by a technician with the stove off and disconnected the mains.

The control panel of the stove has trouble examine sensors. When the sensor detect the abnormal work temperature (below

40^) , or the other sensor's temperature is above 70^ the auto-control temperature switches will react accordingly. When

temperature is below 30^ C, the safety control system will stop the stove automatically; when the other sensor, fixed into the

hopper, detect the temperature is above 70^ C, the stove will be shut down.

The general troubles, the possible reasons and the solutions are as following, after solving problems, start the stove again:

problems reason solution
1. The start light does not light when power is on	No power in stove or in the control panel.		Check the power and wires.
2. The blower doesn't work after pressing the start bottom. (option with boiler)	It is normal.It will start automatically when the temperature is above 30 degrees on the venting pipe.		Please wait
	No power in stove or in the control panel.Or Unplugged on the mother boardThe low temperature sensor is broken		Check the power and wires.Plug itReplace it
3. No feeding after 20 seconds of starting.There are three stages for the feeding process.One is during the several minutes, feeding is constantly. "Feeding" is showing on the LCD displayTwo is the following couple minutes, the feeding light is off.."Lightling" showing on the DisplayThe last stage is that feeding Every several seconds all the time after previous stages.
