Exploring your Greenflame Wood Pellet Boiler

How your Greenflame 28 Wood Pellet Boiler Operates

The Greenflame 28 User Interface has been designed to allow the User to carry out the basic operational and maintenance functions while an advanced digital control systems operates in the background controlling combustion, temperature control and modulation within the pre-determined safety parameters. Each operational ‘cycle’ has several distinct phases:

Ignition – Ignition is the phase where the initial ignition of the fuel takes place and develops a fire bed with enough heat and intensity to enter Run Mode. Sub-stages within the Ignition Stage are:

Pre-Heating – During this stage the heating resistance heats up to a temperature to ignite fuel.

Pre-Load – A starting charge of fuel is introduced into the burner.

Variable Ignition – Ignition of the fuel is attempted by directing hot air at the fuel. If a flame is detected by the end of this stage it enters the last stage of ignition.

Stabilisation – This final ignition stage aids further development of the flame before allowing the system to enter

Run Mode.

Run Mode – The system runs at full power until it reaches a pre-determined water temperature below the set point. Once it exceeds this temperature it enters the Modulation Phase.

Modulation – This phase allows the system to slow down and find the optimum running conditions and temperature to match the heat load of the property. Once the water temperature finally reaches the set point the system enters Standby stage.

Standby / Extinguishing – Standby is reached when there is no further heat demand by the property and extinguishing of the fire bed is required to stop further heat generation. Once the fire bed has been extinguished the system waits in Standby until such time as the water temperature drops below a pre-determined level below the set point. Once this temperature is reached the cycle is repeated.

“The Clean Air Act 1993 and Smoke Control Areas”

Under the Clean Air Act local authorities may declare the whole or part of the district of the authority to be a smoke control area. It is an offence to emit smoke from a chimney of a building, from a furnace or from any fixed boiler if located in a designated smoke control area. It is also an offence to acquire an "unauthorised fuel" for use within a smoke control area unless it is used in an "exempt" appliance ("exempted" from the controls which generally apply in the smoke control area).

The Secretary of State for Environment, Food and Rural Affairs has powers under the Act to authorise smokeless fuels or exempt appliances for use in smoke control areas in England. In Scotland and Wales this power rests with

Ministers in the devolved administrations for those countries. Separate legislation, the Clean Air (Northern Ireland)

Order 1981, applies in Northern Ireland. Therefore it is a requirement that fuels burnt or obtained for use in smoke control areas have been "authorised" in Regulations and that appliances used to burn solid fuel in those areas

(other than "authorised" fuels) have been exempted by an Order made and signed by the Secretary of State or

Minister in the devolved administrations.

Further information on the requirements of the Clean Air Act can be found here: http://smokecontrol.defra.gov.uk/

Your local authority is responsible for implementing the Clean Air Act 1993 including designation and supervision.

Pre-Installation Considerations

Pellets

Wood pellets are manufactured by hot-extruding compressed sawdust which is produced during the working of natural dried wood. The compactness of the material comes from 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 pellet with characteristics which vary depending on what mixture of woods is used. The diameter varies between 6 mm and 8 mm, with a standard length in the range 5 mm to 30 mm.

Good quality pellets have a density which varies between

600 kg/m3 and 750 kg/m3, with a moisture content which varies from 5% to 8% by weight.

Besides being an ecological fuel (exploiting timber residues to the maximum and achieving cleaner combustion than is possible with fossil fuels), pellets also have technical advantages. While good-quality timber has a calorific power of 4.4 kW/kg (with 15% moisture, therefore after about 18 months' seasoning), the equivalent figure for pellets is 4.9 kW/kg.

To ensure good combustion, the pellets must be stored in an area that is free of humidity and protected from dirt.

The pellets are usually supplied in 10 kg bags, so storing them is very convenient. Good quality pellets ensure good combustion, thus lowering the emission of harmful agents into the atmosphere.

The poorer the quality of the fuel, the more frequently intervention will be necessary for cleaning the internal

parts, such as the grate and the combustion chamber.

The main certification of quality for pellets in the European market is Enplus-A1 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: 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.

TR Engineering recommends using certified fuel in its appliances to ENplus-A1 The use of fuel of inferior quality or not conforming to the specification given above compromises the running of your appliance and can therefore lead to the termination of the guarantee and of the manufacturer's responsibility for the product.

TR Engineering domestic pellet appliances run exclusively

on pellets with a diameter of 6 mm.

The Greenflame 28 has been recommended as suitable for use in smoke control areas when burning Enplus-A1 pellets.

CONSIDERATIONS FOR INSTALLATION

IMPORTANT!

Installation and assembly of the appliance must be

carried out by qualified personnel.

The appliance 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 (EN73-23)

Capable of taking an adequate system for smoke discharge

Provided with external ventilation (if located indoors)

Provided with an earth connection complying with CEI 64-8

The appliance must be connected to a flue pipe or an internal or external vertical duct conforming to current

standards UNI7129 - 7131 9615.

The boiler must be positioned in such a way that the

power isolation fuse is accessible.

IMPORTANT!

The boiler 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 cause smoke staining.

Also take care because the fumes are very hot and almost invisible, and can cause burns on contact.

It is recommended that Carbon Monoxide monitors are located in living areas and within the room containing the

heating appliance (in the case of indoor models).

OPERATING AREA

For proper functioning, the appliance should be positioned in a location where it is able to take in the air necessary for combustion of the pellets (about 40 m3/h must be available), as laid down in the standard governing the installation and in accordance with local national standards. All louvres on the external casing of the boiler must be un-obstructed at all times as these allow air for combustion and for cooling to enter the appliance enclosure. Heavy snowfall can also obstruct the air in-take louvres and cause the appliance to not burn clean. Smoke emanating from the flue is a symptom of this. Snow must be cleared from around the appliance at the earliest opportunity.

Where the appliance is to be installed indoors it is not permissible to install the appliance where another heating appliance is installed (fireplace, stove etc.) which does not have its own independent air intake. Locating the appliance in a room with an explosive atmosphere, e.g. workshop or tool shed, is prohibited. The floor of the room where the appliance is to be installed must be

strong enough to take its weight.

If the walls are not flammable, position the appliance with a clearance to the rear of at least 45 cm. For flammable walls, keep a minimum distance of 45 cm at the rear, 30 cm on the sides and 150 cm at the front.

If the flooring is made of wood, provide a floor protection surface in compliance with current national standards.

Service Clearances

The minimum service clearances around the appliance are as follows:

Rear – 600mm

Side (lid hinge side) – 600mm

Side (lid open side) – 900mm

Front – 1200mm

CONNECTION OF THE FLUE

TR Engineering recommends that the Therminox range of stainless steel insulated flue pipe is used with this product.

A full range of straight, offset, elbow and ‘T’ elements is available to overcome any obstruction which the flue should avoid. The proper draught conditions in the flue is critical for the efficient working of wood pellet boilers. The flue can exit the boiler house/garage through the roof or through the wall by using a bend on the flue. The combustion chamber works in negative pressure. The smoke duct for the discharge of fumes will also be under negative when connected to an efficient flue pipe as directed.

All sections of the flue must be capable of inspection and removable to enable periodic internal cleaning.

Position the appliance bearing in mind all the instructions and considerations above.

IMPORTANT!

All 90 degree changes of direction in the flue pipe must

be either removable or capable of inspection.

THE FLUE PIPE RUN MUST NOT INCLUDE MORE THAN 2-3

METRES OF HORIZONTAL PIPE MUST AND NOT MORE

THAN THREE 90° ELBOWS (INCLUDING ‘T’s). IT IS ALSO

ADVISABLE NOT TO EXCEED 8 METRES IN LENGTH WITH

THE PIPE Ø 100 mm.

TR Engineering recommends the use of 100mm

Therminox flue for use with this appliance.

OPERATING PROBLEMS CAUSED BY DRAUGHT DEFECTS IN

THE FLUE

Of all the weather and geographical conditions which affect the operation of a flue pipe (rain, fog, snow, altitude a.s.l., exposure to sunlight, direction of facing), the wind is unquestionably the most decisive. In fact, along with thermal depression caused by the difference in temperature inside and outside of the chimney, there is another type of depression or over-pressure: dynamic pressure caused by the wind. An updraft always increases depression and hence draught. A crosswind increases depression provided the cowl has been installed properly.

A downdraft always decreases depression, at times inverting it.

Besides the direction and force of the wind, the position of the flue and the cowl with respect to the roof of the building and the surrounding landscape is important.

The wind also influences the operation of the chimney indirectly by creating high-pressure and low-pressure zones, not only outside the building but inside as well. In rooms directly exposed to the wind (2), an indoor highpressure area can be created which can augment the draught in boilers, stoves and fireplaces, but it can be counteracted by the external high pressure if the cowl is situated on the side exposed to the wind (1). On the other hand, in the rooms on the opposite side from the direction of the wind (3), a dynamic depression can be created which competes with the natural thermal depression developed by the chimney, but this can be compensated for (sometimes) by locating the flue on the opposite side from the direction of the wind (4).

IMPORTANT!

The operation of the pellet boiler 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 boiler carried out by qualified TR

Engineering personnel.

PLUMBING CONNECTION

IMPORTANT!

The connection of the boiler to the plumbing system must be carried out ONLY by specialized personnel who are capable of carrying out installation properly, in compliance with current standards in the country of installation.

If installation of the boiler will involve interaction with another, pre-existing system complete with heating equipment (gas boiler, methane boiler, fuel oil boiler, etc.), it is even more advisable to call in qualified personnel, who subsequently will be responsible for conformity of the system with current applicable law.

TR Engineering will not be held responsible for damage to persons or things in the event of failed or incorrect operation if the aforementioned warnings are not complied with.

For connection of the plumbing system to the appliance, the user should refer to chapter 4, INSTALLATION AND

ASSEMBLY; specifically, paragraph 4.5, CONNECTION TO

PLUMBING SYSTEM.

PREPARING THE BASE

Careful planning at an early stage will greatly help the installation process and make sure that all the required clearances are adhered to for servicing and that any potential issues with the routing of the flue can be resolved.

The Greenflame pellet boiler should be positioned on a concrete plinth at least 50mm high and should project a minimum 100mm beyond the sides and the rear of the appliance and at least 600mm to the front. The plinth must be capable of supporting the weight of the appliance when full with fuel and the plumbing system has been filled with water.

Use the template below for constructing the plinth and for positioning the flow and return pipe work and electrical supply.

Refer to service and access clearances around the appliance on Page *.

ELECTRICAL CONNECTIONS

Electrical installations should only be carried out by suitably qualified and certified electricians. If in doubt on any issue relating to the electrical connections on the appliance contact TR Engineering Technical Support or your local dealer for guidance before carrying out any

connections.

The Greenflame boiler must be supplied with a 230V 50 Hz electrical supply via a two pole isolation switch rated for

Overvoltage Category III and protected with a 6A circuit breaker. Also, the unit shall have a 30mA RCD installed into the mains supply. It is recommended that a power isolation switch is located adjacent to the boiler to isolate the power during servicing and maintenance but also out of the reach of children and to prevent accidental turning off of the mains power.

Room thermostats shall be supplied / controlled by safety extra low voltage.

Brown - Time Clock Control Live

Only authorized TR Engineering personnel may open the control panel on the boiler. Any interference with the

wiring in the control panel will invalidate the warranty.

The boiler and complete plumbing system must be adequately earthed and bonded in accordance with local

Building Regulations and Bye- Laws.

BOILER CONTROL PANEL SCHEMATIC

Only authorised TR Engineering personnel may open the control board. Any tampering with the PCB will immediately invalidate the warranty.

WATER CONNECTIONS

The diagram below indicates the plumbing connections at the rear of the boiler. The return connection is factory fitted with a 25/6 Standard pump

Incorrectly sized expansion vessel will invalidate the warranty. A minimum 18 litre vessels is recommended for the boiler plus additional expansion for the heating and domestic hot water system.

The boiler can be plumbed into either an open vented system (the maximum static head of water permissible is

90 ft. (27.44 meters) or a sealed system. If plumbed into a sealed system an appropriately sized expansion vessel should be used and installed as per manufacturer’s instructions. The expansion vessel should be sized based on the water capacity in the boiler and the water in the entire heating system.

The pump is on the return pipe work just before the boiler.

It is recommended that a by-pass pipe between the flow and return is used with a valve to regulate the temperature of the water returning to the boiler. Also, the system designer should ensure that there is adequate provision in the system for heat dissipation from the boiler during the shut-down / extinguishing phase. An automatic air vent and pressure relief valve must be fitted to the flow pipe work immediately outside the boiler. The pressure relief valve should be piped to a drain to prevent injury to the User or Service Technicians if it is activated. All unused connections should be sealed with blanking plugs.

A non-return valve should be fitted to prevent backsiphonage.

Once the plumbing has been completed the system should be fully flushed to clear any debris which may have become lodged in the pipe work. The system should generally be filled from the lowest point on the system to force any air to the highest point where it can be vented.

The flow pipe on the boiler is fitted with a manual air vent for venting air from the boiler. The system must then be filled and the pump can be run continuously for a few hours to completely de-aerate the system. Hold the ESC button on the controller for 3 seconds to activate the pump. Repeat the procedure to turn it off. Only when the system has been fully vented can the boiler be commissioned.

The installation and the design of the central heating system must be in accordance with BS EN 14336:2004:

Heating Systems in Buildings. Installation and commissioning of water based heating systems. BS EN

12828: 2003; Heating Systems in Buildings. Design of water based heating systems. BS EN 12831: 2003: heating systems in buildings. Method for calculation of the design heat load. seal.

BOILER OPERATION & MAINTAINANCE

The Greenflame 28 has been developed to ensure that the user is able to carry out the most basic functions in a safe and convenient manner. Once the installation has been successfully carried out the user interaction is quiet simple from a regular inspection on the combustion chamber to remove ash to filling the hopper with pellets.

Turning ON and OFF the boiler

It is recommended that your boiler is controller by an external time clock. The time programs should be set to the times that heat is required at different periods throughout the day. You should also make allowance for the ignition time of the appliance, i.e. the time it takes from when the time clock signals the boiler to start until the flame has fully developed in the appliance (usually approx. 10-20 minutes).

When choosing your programs on your time clock it is recommended that you program the clock for long runs instead of short runs. This gives the boiler time to settle and match the heat demand of the property. It is also when the boiler is most efficient.

If the boiler is not being controlled by a time clock then it can be turned on and off locally at the display on the boiler control panel. Hold the ON/OFF button for 3 seconds to start the boiler. Hold the ON/OFF button for 3 seconds to turn off the boiler.

Emptying the Ash Pan

The boiler contains two areas where ash needs to be removed at regular intervals.

The primary ash pan is located in the main combustion chamber. The frequency of emptying the ash pan is determined by the length of time the boiler has been running and under what load conditions. Once the ash in the ash pan has reached the top then it should be emptied.

A daily check during the first few days of operation will give an indication as to when it needs to be emptied.

Always make sure that before you open the main combustion chamber door that the boiler has been switched off as has been allowed to cool down sufficiently so as not to cause injury.

Always empty ash into a metal container as ash which may appear cool could be hot in the centre.

Never use plastic brushes or dust pans to clean ash from the boiler.

Always use heat resistant gloves when handling the ash pan or cleaning the boiler.

When the combustion chamber door is opened, even with the boiler in the OFF position, the combustion fan

will run at full power.

The secondary ash pan is located under the main combustion chamber. This needs to be emptied less frequently.

Emptying the Ash Pan

The boiler contains two areas where ash needs to be removed at regular intervals.

The primary ash pan is located in the main combustion chamber. The frequency of emptying the ash pan is determined by the length of time the boiler has been running and under what load conditions. Once the ash in the ash pan has reached the top then it should be emptied. A daily check during the first few days of operation will give an indication as to when it needs to be emptied.

Filling With Fuel

The boiler will indicate when the level of pellets reaches a low level. The system will shut down and will wait for the hopper to be refilled.

Open the pellet hopper lid and carefully pour approved pellets into the hopper.

Never fill the hopper above the guard mesh across the opening of the hopper.

Never allow any foreign material to enter the hopper.

This will lead to the malfunction of the auger system and could cause damage to the appliance and invalidate your warranty.

Always close the lid to the hopper once it has been filled with pellets.

Never leave the hopper lid open for prolonged periods as rain or moisture can affect the pellet.

Always supervise children when the hopper lid is open in case foreign material is placed into the hopper or children climb into the hopper.
