“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 designed 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.

3. Pre-Installation Considerations

3.1. 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 6mm and 8mm,

with a standard length in the range 5mm to 30mm. Good
quality pellets have a density which varies between
600kg/m3 and 750kg/m3, with a moisture content which
varies from 5% to 8% by weight.

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

4.9kW/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 fuel, the more frequently

intervention be necessary for cleaning the internal parts,

such as the grate and the combustion chamber.

The main certifications of quality for pellets in the European
market are Enplus-A1 these ensure respect of:

 Calorific power: 4.9kW/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.

Greenflame Wood Pellet Boiler 13-18kW

a location where it is able to take in the air necessary for
combustion of the pellets (about 40m3/h must be available),
as laid down in the standard governing the installation and in
accordance with local national standards. All lovers 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 louvers 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 rear of at least 45cm.
For flammable walls, keep a minimum distance of 45cm at
the rear, 30cm on the sides and 150cm at the front.

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

T R Engineering Ltd 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.
T R Engineering Ltd domestic pellet appliances run
exclusively on pellets with a diameter of 6mm. It is
recommended that the brand of pellets used during
commissioning are used during normal operation. If you
change your pellet supplier or brand re-calibration may be
necessary and a call-out charge will apply.

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

3.2 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 50Hz (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
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.

3.3 Operating Area

For proper functioning, the appliance should be positioned in

SERVICE CLEARANCES

The minimum service clearances around the
appliance are as follows:
Rear – 50mm Nominal
Ends – 300mm
Front – 600mm
Concrete plinth should extend 300mm past front
and ends.

Greenflame Wood Pellet Boiler 13-18kW

3.4 Connection of the Flue

The proper draught conditions in the flue are 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.
For locating the boiler against a wall ensure
adequate flue support using approved wall
brackets.

THE FLUE PIPE RUN MUST NOT INCLUDE MORE THAN 2-3
METRES OF HORIZONTAL PIPE AND MUST MORE THAN

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

ADVISABLE NOT TO EXCEED 8 METRES IN LENGTH WITH THE
PIPE OF 100mm DIAMETER.

3.5 How the Greenflame Overcomes Issues
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, 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 over­pressure; dynamic pressure caused by the wind. An up
draught always increases depression provided the cowl has
been installed properly. A down draught always decreases
depression, at times inverting it.

Besides the direction and force of the wind, the position of
the flue and cowl with respect to the roof of the building and
surrounding landscape is important.
The Greenflame air flow regulation system is equipped to
deal with the conditions referenced above by regulating the
air flow through the combustion chamber. An air flow sensor
is mounted on the air intake duct and measures the volume
of air drawn pulled though the burner pot by the exhaust
fan. If down draught conditions are present and air flow
increases, the exhaust fan increases speed to maintain the
required air flow. The opposite reaction occurs in up draught
conditions.

IMPORTANT!!!

In areas of extreme weather, especially wind,
additional measures may need to be provided for,
in consultation with T R Engineering Ltd. Flue
draught stabilisers will be required where natural
draught of >100Pa is present or anti-downdraught
cowls will be required where downdraught of
>10Pa exists.

3.6 Plumbing Connections

IMPORTANT!!!

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

T R Engineering Ltd 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.

It is recommended that a suitable anti-freeze
solution is added to the heating system to prevent
the freezing of water within the boiler in the case
of a power outage. The boiler has an anti-freeze
function which activates the pump in the event of
the temperature in the boiler dropping below 5°C.

4. Installation and Assembly

4.1 Unpacking

The Greenflame slim pellet boiler will come packaged on a
single pallet. The flue will be packaged separately.

The materials which make up the packaging are 100%
recyclable. Their storage or recycling is therefore the
responsibility of the final user, in compliance with local
regulations. Do not store the boiler without its packaging.
Remove the nylon strapping, cardboard packaging and
bubble wrap and recycle in the appropriate manner.

When unpacking the boiler use the checklist below to ensure
that all the required components to complete the kit have
been supplied. In the unlikely event of an omission you must

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

4.3 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 T R
Engineering Ltd Technical Support or your local
dealer for guidance before carrying out any
connections.

The Greenflame boiler must be supplied with a 230V 50Hz
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.

Unpacking Checklist

** The User Manual Pack includes a User Manual, Quick Step

User Instructions, Commissioning Report, keys for lockable
doors and heat proof gloves.

** Flue components listed above may vary depending on

where the boiler is being installed. Please check with your

4.2 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 min.
300mm beyond the sides and the front of the appliance. The

4.5 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 vessel is
recommended for the boiler plus additional
expansion for heating and domestic hot water
system.

Ensure that the pre-charge in the vessel is equal to
the initial system fill pressure of between 1-1.5
bar.

The boiler can be plumbed into either an open vented
system (the maximum static head of water permissible is
90ft. (27.44m) 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 back siphonage.
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.

6. Boiler Operation & Maintenance

The Greenflame slim 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 quite 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 controlled by an

external time clock. The time programs should be set to
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 be emptied. A
daily check during the first few days of operation will
give an indication as to when it needs to be emptied.

When the combustion chamber door is opened, even with
the boiler in the OFF position, the combustion fan will run at
full power.

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

Always allow boiler to cool down before
opening the combustion chamber door.

Unscrew the two fixing knobs on the ash
pan.

Carefully remove the ash pan and
dispose of the ash into a metal
container.

If the burner pot contains ash remove the pot for the
holder and scrape the contents into a container. Also
make sure that the air holes are clear. Carefully replace
the pot ensuring that it is properly seated.

If the burner pot contains ash remove the pot for the
holder and scrape the contents into a container. Also
make sure that the air holes are clear. Carefully replace
the pot ensuring that it is properly seated.

Failure to replace the pot correctly can cause
damage and invalidate the warranty. Your installer
will show you how to do this correctly.

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 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.
