2 INSTALLATION INSTRUCTIONS

The boiler must be installed by personnel authorised by the relevant national authorities, in compliance with the applicable laws and regulations.

This boiler is suitable for heating water to a temperature below boiling point at atmospheric pressure. It must be connected to a heating installation and/or a domestic hot water distribution network, which must always be compatible with its performance and power.

This appliance must only be used for the purpose for which it has been expressly designed. Any other use is considered unsuitable and therefore hazardous. The manufacturer shall not be considered liable under any circumstances for damage caused by unsuitable, erroneous or irrational use. Remove all the packaging and check the contents are complete. In case of doubt, do not use the boiler. Contact your supplier. Keep the packaging elements out of reach of children, as they can be dangerous.

When you no longer wish to use the boiler, disable the parts that could be a potential source of hazard.

2.1 Location

The boiler must be installed in a sufficiently ventilated site, away from humidity. It must be located so that the air grilles on the premises are not obstructed and normal boiler maintenance is possible even if it is placed between items of furniture. One metre of free space must be left above the boiler for this purpose. The appliance should be located in a part of the installation where it cannot be struck by a vehicle.

2.2 Hydraulic installation

The hydraulic installation must be made by qualified personnel. The applicable installation legislation is to be complied with, and the following recommendations should also be taken into account:

- It is obligatory and essential to install an anti-condensation valve (shunt valve/Load valve) with the boiler, to prevent any water condensation in the heat exchanger. If this requirement is not complied with, EKOPOWER’s guarantee of the appliance will automatically be null and void. Make sure it is installed in the correct location and diverting the water in the correct direction.

- The inside of the installation piping should be thoroughly cleaned (flushed) before switching on the boiler. A magnetic filter should also be fitted.

- We recommend inserting cut-off valves between the installation piping and the boiler to simplify maintenance tasks.

- Leave adequate free space around the boiler for carrying out any maintenance and repair operations.

- Drain valves and suitable devices for correctly bleeding the air from the circuit during the boiler filling stage should be fitted.

- Install all the necessary safety elements (expansion vessel/tank, safety valve, etc.) to comply with the applicable regulations for the installation. Make sure there is adequate expansion area in open vented systems tank.

- If the boiler is installed at a lower height than the heating installation, it is recommendable to create a siphon at the boiler outlet, to prevent the installation from heating up due to natural convection when heating is not required.

-Circulation pump is in the correct location and circulating the water in the correct direction.

EKOHEAT

2.3 Fuel

The EkoHeat boilers must be fuelled by EN PLUS certified wood pellet. The EN PLUS certificate assures that the fuel’s humidity levels and calorific value are ideal for optimum boiler functioning. If this requirement is not complied with EKOPOWER’s guarantee of the appliance will automatically be null and void.

The following points should be taken into account for correct fuel storage:

- The stored pellets should be kept dry all year round.

- The applicable legislation in each country for correct fuel storage must be complied with.

Wood pellets are made from wood shavings and sawdust and are used in highly efficient and convenient automatic wood boilers. Because they have a low moisture and ash content wood pellets burn very efficiently. What’s more they are compact and easy to store. Typically pellets come in bags (ideal for stoves or smaller boiler systems) or are delivered in bulk by truck (ideal for boiler systems with bulk stores). Wood pellets can be ordered from local fuel merchants.

Pellets facts (Typical)

Dry matter content 90-92%

Ash content 0.5%

Diameter 6-8mm

Length 4”diameter,

Density 650 kg/m3,

Volume 1.54m3/tonne pellet,

Energy 4.7 kWh/kg pellet

Benefit 1kg wood pellet replaces 0.41kg of light fuel oil

Wood pellets are upgraded or refined wood fuels which have been produced from sawdust, grinding dust, shavings, bark or cutter chips by drying and pressing. No additives are needed to produce them. Lignin released in the pressing process binds the wood material. They are compact and easy to store and use for fully automatic burning in wood pellet boilers or stoves.

Good quality wood pellets with a moisture content of 8% will have a calorific value of approximately 4,700 kWh/tonne.

EKOHEAT

6

2.4 Installing the Hopper

EKOPOWER supplies a reserve tank for storing the pellets with the boiler. The tank is reversible and can be mounted on either the left or right side of the boiler. There are 2 sizes, 320kg & 160kg.

IMPORTANT: Ensure the height of the elliptical holes on the sides of the boiler and on the reserve tank coincide, for correct insertion of the feed auger. To do this, make the necessary adjustments for height and depth.

EKOHEAT

3 FLUE INSTALLATION

The EkoHeat boiler is a biomass boiler and it is essential for it to be connected to a flue, i.e. a smoke duct able to create a pressure drop, which in this case should be between 15-20 Pascal’s (Pa)or 0.15-0.20mbar, in compliance with the applicable laws to this regard.

The com must be installed by qualified personnel and must comply with the regulations in force. The following recommendations should be taken into account:

- It should have 25mm insulation.

- It should be insulated from flue terminal of the boiler to the cowl.

- It should have a draft stabilizer fitted.

- It should be independently located, with a separate flue for each boiler.

- It should be vertical, avoiding any angles greater than 45º.

- It should always have the same diameter. It is recommendable for it to be circular, and never any narrower than the boiler outlet.

- It is above the eaves line by about 1 metre or 600mm if coming out near the roof apex.

- It should have a storm cowl fitted.

IMPORTANT: It is obligatory to install a fume inspection plate with condensation collection, to remove the condensation generated in the flue. Otherwise, the condensation may reach the inside of the boiler and cause irreparable damage, which would not be covered by EKOPOWER’s guarantee. The condensation pipe should lead to a drain outlet, as a large amount of water may be generated. This connection must be made in compliance with the regulations for draining off condensation water to the drain network.

IMPORTANT: It is recommended to install a draught stabiliser to prevent any pressure drop variations in the flue due to atmospheric conditions, which could affect correct boiler combustion. This draught stabiliser must be installed below the fume inspection plate to prevent any leakage of combustion gases.

IMPORTANT: It is recommended to install a storm cowl on the Flue.

IMPORTANT: If the draft is below 10 Pascal’s (Pa), some of the tabulators must be taken out or a 10mm hole drilled on the cap of the tabulator or both. This would be dependent the on flue gas temperature.

EKOHEAT

15

From July 1st 2013 it will be mandatory for manufacturers to apply CE Marking to any of their products that are covered by a harmonised European Standard.

Each Harmonised European Standard defines requirements for CE marking of that product and has two main components:

* Initial Type Testing

* Factory Production Control

Both must be obtained to achieve CE Marking.

3.1 Flue Diagram

EKOHEAT

16

3.2 Flue structure

The design having almost no thermal bridging between the chimney liner and body ensures a quick stabilization of flue gas temperatures and the existence of a strong draught. This enhances the performance of the appliance. It must be constructed from concentric cylinders commonly referred to as the chimney liner and body. The body is made from 304 grade stainless steel which carries the structural load. It has a bright polished finish and is completely weather proof due to its high quality continuously seam welded finish. The liner of the flue is made from 316 grade stainless steel and is designed to automatically cope with the thermal elongation due to changes in temperature. It also must offer excellent resistance against corrosion; this would be to its molybdenum alloy content structure.

The chimney is insulated with a densely packed insulation (25mm) which results in a low heat conductivity to the walls of the chimney. All components have specially developed male and female formed ends. Together with a developed locking band system both strengthen the joints and ensure the excellent gas tight properties of the chimney. As stated there must be a minimum distance of 80mm from the outer body of the chimney to any combustible material. However if the chimney passes through a joist or slab then clearance at floor and ceiling joist must be established by the use of a Fire-stop arrangement. No combustible material should protrude beyond the 80mm safety lugs attached. If the chimney passes through a cupboard, attic or separate compartment area to the boiler it should be adequately protected by a non-combustible casing material which must be spaced from the chimney to satisfy the minimum distance stated. This is to ensure that accidental contact of any combustible material or human contact to the surface of the chimney will not occur. Protection in the attic can also be provided by a rigid mesh structure positioned at the relevant distance to the chimney.

IMPORTANT: No joints in the chimney sections should be made in the joist area or where there is no access.

The connection to the flue pipe or appliance must be sealed using an adaptor. This can be sealed with fire cement or suitable alternative, and this connection should be made in the same room as the appliance itself. The weight of the chimney should be adequately supported using the correct brackets. Where the building is to support the lateral and vertical load it should be inspected to ensure it is capable of supporting the extra load. If the chimney is installed internally it should be supported with the use of wall brackets and fire stops determined by the route chosen. Where a chimney protrudes 1.5M beyond its last support a guy wire bracket support system should be used. On completion of installation a chimney plate must be completed and positioned in an area close to the chimney base for future reference.

EKOHEAT

17

3.2 Cleaning / Maintenance The chimney should be inspected regularly and cleaned at least once a year. This should be carried out with the use of a brush which should not be made from black steel. The chimney should be maintained to ensure that the construction remains in good condition. Any components showing signs of deterioration which may affect performance should be replaced under professional advice, any evidence of leakage identified by smoke staining should be rectified immediately. For chimney information refer to the chimney plate. 3.3 Flue termination As a chimney protrudes through a roof structure it must be sealed with a lead flashing to suit the specific roof pitch. The lead flashing base should be worked into the roof structure to ensure rain water run off situation is achieved. The lead flashing up-stand section should then be trimmed back with a small amount of clearance to ensure the flue diameter being used passes through it snugly. The top of the lead flashing connected to the chimney body should be carefully sealed with a flash-band mastic or denso tape. A storm collar should then be fitted to the flue body directly over the top of the flashing unit. To fit the storm collar place it around the flue body and tighten the nut and bolt arrangement. It is recommended that a small amount of flash band mastic or high temperature silicone is used to seal the immediate area around the top of the storm collar. The cowl is the last component to be fitted to the flue installation. For full detail of chimney termination heights see Part J of the building regulations. 3.4 Non load bearing components Wall Bracket: 1.5M intervals or centrally between base/intermediate wall supports for all diameters Guy wire bracket: 1.5 meter intervals beyond last support for all diameters. Roof centring Plate: Attached to chimney to centralise \ stabilise before passing through pitch roof for all diameters. On long external chimney runs a base wall support should be installed to support the tee piece to a total installed height of 3.5meters. An additional intermediate wall support must be used every 3.5meters beyond this point with a wall bracket situated centrally between both load bearing members. If an offset in a chimney run is necessary i.e. to avoid fascia and soffet, an additional wall bracket must be installed directly above the offset to provide extra lateral support. See installation drawings.

4 STARTING UP THE BOILER

4.0 Prior warnings

Repair and maintenance of the boiler must be carried out by a qualified professional, authorised by EKOPOWER. For optimum functioning and conservation of the boiler, it should be serviced annually.

Carefully read this instruction manual and keep it in a safe, easily-accessible place. EKOPOWER will not be liable for any damages caused by failure to follow these instructions.

Before any servicing, disconnect the boiler from the mains.

4.1 Filling the installation

The hydraulic installation must include a fill valve, a manometer, drain valves and the necessary hydraulic components for correctly filling the installation.

To fill the installation, open the fill valve until the installation manometer shows a pressure of 1 - 1.5 bars. The installation must be filled slowly, bleeding the air from the water circuit using the drain valves provided on the same. Close the fill valve after filling.

IMPORTANT: Switching on the boiler with no water inside could result in serious damage.

4.2 Electrical Connection

The EkoHeat boiler must be protected by 5 amp fuse unit and RCD or RCBO device be fitted on electrical supply. There is a 4 amp fuse located on main circuit board. It is important to disconnect electrical supply when doing any maintenance on the boiler. The appliance MUST be earthed.

4.3 Start-up

In order for the guarantee to be valid, the boiler must be started up by personnel authorised by EKOPOWER. Before beginning start-up, the following must be complied with:

- The boiler must have an electrical supply.

- The installation must be filled with water (the pressure must be between 1 and 1.5 bar).

- The hopper must be filled with fuel.

The start-up sequence is as follows:

- Check the flue is correctly installed using a draft gauge.

- Check the external hydraulic anti-condensation kit is correctly installed.

- Check the reserve tank and the feed auger are correctly installed. The feed auger must be calibrated for correct boiler functioning (See “Feed Auger Calibration” page 27). Check the right type of fuel is being used (it must be EN PLUS).

- If the installation has flow and return valves, check they are open.

4.4 Installation delivery

After the initial start-up, the Technical installer will explain to the user how the boiler functions, making any observations they consider relevant. The installer is responsible for clearly explaining to the user the functioning of any control or regulation device forming part of the installation but not supplied with the boiler.

7.7 Auger calibration

This display is used to calibrate the fuel feed auger required for correct boiler functioning. It is essential for the boiler feed auger to be calibrated on start-up and whenever the fuel supplier is changed (not all suppliers provide granules of the same density and size). Calibrating the boiler feed auger adjusts the optimum amount of pellets required to supply the burner and produce the correct power and combustion.

If the fuel in the hopper runs out, fill the feed auger with pellets again. To do this, follow the calibration instructions up to point 8. In this case it will not be necessary to calibrate the feed auger again, unless you change your pellet supplier.

A weighing scales and a suitable pellet collection container are required for this calibration procedure. The steps for correctly calibrating the feed auger are as follows:

EKOHEAT

28

This process must be carried out twice to ensure the correct amount of pellets have been added.

IMPORTANT: Calibrate the feed auger before starting up the boiler for the first time.

IMPORTANT: Calibrate it again whenever you change your fuel supplier.

14 SAFETY PRECAUTIONS

14.1 Carbon monoxide detector

Many people are killed each year, and many more suffer ill health from carbon monoxide (CO) poisoning. CO is an invisible, odourless, tasteless and extremely toxic gas. It is produced by appliances and vehicles burning fuels, such as coal, oil, natural gas, wood, etc. CO is absorbed by red blood cells in the lungs in preference to oxygen – this result in rapid damage to the heart and brain from oxygen starvation.

High levels of CO in a house can be caused by:

* Incorrectly or poorly installed fuel-burning appliances

* Blocked or cracked chimneys/flues

* No ventilation, blocked vents or draught-proofing which makes areas with fuel burning appliances airtight.

Suitable locations:

* A carbon monoxide detector should be located in the room with the boiler

* It should be installed on the ceiling 300mm from walls or light fittings.

* Between 1M to 3M horizontally from appliance

* If it is mounted on a wall, it should be located at a height greater than the height of any door or window but still be at least 150mm from the ceiling.

* If there is a partition in the room, the CO alarm should be located on the same side of the partition as the boiler.

* In rooms with sloped ceilings, the CO alarms should be located at the high side of the room.

Unsuitable locations:

* Next to a door, window, air vent or anywhere that it would be affected by draughts.

* Next to a extractor fan

* Over heat sources such as radiators or hot air vents.

* Where dirt or dust could block the sensor

* Near paint, thinners, solvent fumes or air fresheners.

* Do not fit alarm until all building work is complete to avoid contamination

This information is only precaution information; it does not state that CO emissions will leak from an EKOPOWER boiler. EKOPOWER does not take any responsibility from damages caused from poor installation due to an installer. Good ventilation is extremely important. NEVER IGNORE THE ALARM.

Attention:

It is recommended that the installer preform a 10 minute CO room test with their analyser when installation is complete and working.

EKOHEAT

37

14.2 Ventilation

Part J of the Second Schedule to the Building Regulations, 1997, provides as follows:

A heat producing appliance shall be so installed that there is an adequate supply of air to it for combustion and for the efficient working of any flue pipe or chimney.

If an air extract fan is fitted in a building containing the boiler (other than a room-sealed appliance), the appliance and flue should be able to operate effectively when the fan is running.

A permanent air entry or opening with a total free area of at least 550 mm2 per kW of rated output above 5 kW shall be provided but in no case less than 6500 mm2. Where a flue draught stabiliser is used the total free area should be increased by 300 mm2 for each kW of rated output.

Attention:

If the boiler is installed in an air tightness premises, ventilation should be piped into the room from outside to where the boiler is installed.

If there are other oxygen consuming appliances in the room with the boiler, provisional air should be taken into account. If one vent is inadequate to service the needs of all the appliances place a second vent at a lower level behind the boiler.

All air vents should be piped direct from the boiler room to outside air source, not from room to room (internal air).

Make adequate provision that air vents cannot be blocked both inside and outside the building. Place necessary warning signage.

Warning:

Inadequate ventilation can result in carbon monoxide being produced which in return could result in health damage or loss of life.

EKOHEAT

38

15 CLEANING THE ASH DRAWER

The EkoHeat boiler is equipped with an ash drawer, where the solid residues from the burnt fuel are collected on cleaning the burner and heat exchanger. This drawer must be regularly cleaned to prevent ash from accumulating and obstructing the bottom of the heat exchanger, which would cause the boiler to switch off. It is recommended to regularly check the drawer and remove the ash that has accumulated.

EKOPOWER supplies an optional ash compacting system for incorporation to the boiler, so that the ash does not need to be removed as frequently.

Safety warnings:

For safe handling of the ash drawer, you should take the necessary safety precautions and wear suitable clothing to protect against possible injury. The following advice should be particularly taken into account:

- Switch off the boiler before taking out the ash drawer. If you take out the ash drawer with the boiler on pause, make sure you have replaced it before switching on the boiler again. It is recommended to wait before taking out the ash drawer until no flame is detected in the burner.

- It is recommended to wear insulating thermal gloves to protect your hands from any burns from hot parts of the drawer.

- It is recommended you wear a protective mask to avoid breathing in any ash particles, particularly in the case of people with allergies or any type of respiratory trouble, who should always wear a mask when carrying out ash removal.

- As the ash to be removed from the drawer may be burning or glowing, special precautions should be taken with regard to the type of container it is emptied into. A metal container is recommended, or the ash should be totally put out on handling, using water or another extinguishing agent.

EKOPOWER shall not be liable for any damage caused to people, animals or property as a result of incorrect handling of the ash drawer or the ash itself.

IMPORTANT: The ash drawer must only be cleaned when the boiler is switched off or on pause.

EKOHEAT

39

16 SAFETY CUT-OUTS

The boiler’s electronic control system may activate the following safety cut-outs to stop the boiler functioning. When any of these cut-outs occur, the boiler will switch off and a description of the cut-out will appear on the display.

IMPORTANT: If any of the safety cut-outs described below should occur repeatedly, switch off the boiler and call your nearest official Technical Assistance Service.

16.1 Burner cut-out

When this cut-out occurs, the message "E05: Burner error" will appear on the digital display. The burner and its fuel supply will be cut off.

This occurs due to burner anomaly or excessive temperature in the burner fuel supply circuit. To unblock it, press the “OK” button.

16.2 No flame cut-out

When this cut-out occurs, the message "E06: Flame defect" will appear on the digital display. The burner and its fuel supply will be cut off.

This occurs when an insufficient flame lux level is detected by the photocell during a certain time lapse. To unblock it, press the “OK” button.

16.3 Temperature safety cut-out

When this cut-out occurs, the boiler digital display will switch off and the electrical supply to the electronic control will be cut off. All the boiler devices will switch off.

This occurs whenever the water in the boiler reaches a temperature of 110 ºC. To unblock it, wait until the boiler temperature drops to below 90ºC and press the reset button on the safety thermostat located on the underside of the electrical panel (see “Control components” page 5).

18.2 Cleaning the burner.

The following procedure is recommended for correctly cleaning the burner:

EKOHEAT

42

IMPORTANT: Always make sure the burner is switch off for a period of time and disconnected from the electrical supply before carrying any maintenance on the burner or boiler.

IMPORTANT: The burner cleaning device can only be lubricated when the boiler is switched off, system cooled and the time programmer disabled.

IMPORTANT: The burner cleaning device should be lubricated if an unpleasant noise is heard. It should be done each year on the annual overhaul, at the least.

18.3 Draining the condensation water

Draining of condensation water from the flue should not be altered in any way and it must be kept free of obstructions. It should be flushed out regular to prevent deposit build up.

18.4 Boiler water characteristics

In areas with water hardness of over 25-30ºfH, treated water or inhibitor must be used in the heating installation to avoid any scale deposits on the boiler. It should be noted that even a few millimetres of scale will greatly reduce the boiler’s heat conductivity, causing a major drop in performance.

Treated water or inhibitor must be used in the heating circuit in the following cases:

- Very large circuits (containing a large amount of water).

- Frequent filling of the installation.

If repeated partial or total draining of the installation is necessary, we recommend filling it with treated water.
