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.
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.
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
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 80 mm.
TR Engineering recommends the use of 80mm 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 high-
pressure 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 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.
Always ensure that all connections are making a watertight
seal.

BOILER OPERATION & MAINTAINANCE
The Greenflame 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.
