1. General Information:
1.1 Introduction:
Sustainable heating solutions are at the forefront of
Trianco’s heating product portfolio. The need to increase the
awareness of alternative sources of fuel to fulfil our energy
demand has never been so great, not only to alleviate world
reliance on fossil fuels but also to encourage more natural
sources of energy supply. Trianco’s renewable portfolio
began with successful introduction of Activair air source heat
pumps, the next step naturally pointed to biomass heating
systems.
Why Biomass?
Wood is one of the most natural and sustainable fuel sources
available to us, it has a carbon neutral cycle as it releases
about the same amount of carbon dioxide into the
atmosphere through burning, as it absorbs during its growth
process.
Controlled in a very similar way to an oil or gas boiler,
Greenflame Eco biomass boilers have clean burn credentials
and super efficiencies in excess of 90%, meaning the range is
a more viable option for properties particularly in rural areas
that currently have an oil or gas heating system installed.
The Greenflame Eco is designed to burn Enplus-A1 pellets
which introduce many benefits such as:
The fuel being from a renewable source; proper
management eliminates the risk of depleting the source;
Biofuel emits only as much CO2that the parent material
absorbs during growth phase;
Low ash content –0.3% - 0.5%;
Possibility to use ash as fertiliser;
Low costs involved in operation;
The cost of pellet is independent to the cost of coal;
1.2 Applications and Benefits of the Boiler:
The Greenflame Eco pellet boiler is designed for heating single
houses, detached and semi-detached houses, offices, garages,
utility buildings, etc. Some of the benefits include:
Very high efficiency that exceeds 91%, obtained by
modern, precisely tested construction;
Virtually full automation –the boiler needs to be supplied
with fuel once every couple of days, depending on
individual needs and atmospheric conditions. The start
and cease of combustion is autonomous;
Utilisation of Lambda probe, and exhaust probe on the
chimney fitting allows to obtain optimal parameters and
high combustion efficiency;
Novel cleaning system which absolves the user of the
need to clean the exchange element –all that is needed is
one general clean per year;
Low level of hazardous substance in exhaust;
Small amount of ash that can be fully utilised as fertiliser;
Very low costs involved in operations of the device.

1.3 Basic Usage Guide:
To ensure correct and prolonged operations of the boiler
please comply with the following rules:
Only fuel approved by T R Engineering (ultimately
Enplus-A1) may be used with this appliance;
It is strictly forbidden to make any changes to the
construction or settings of the boiler; damage of the
worm gear supplying the fuel;
Boiler must always be fitted with water circulation. Not
providing water flow may cause overheating of the
boiler, which in consequence may result in injury or
damage to material goods;
Before starting up please make sure that the boiler room
is properly ventilated and that air and exhaust ducts are
always clean and permeable;
It is crucial to follow all rules and instructions regarding
installation (both central heating as well as electrical)
and boiler usage;
1.4 Users Responsibilities:
User is fully responsible for the usage and maintenance
of the boiler;
Not complying with rules might result in boiler
malfunction, decrease efficiency as well as a shorter life
span;
The boiler should only be operated by a competent
person;
2. Technical Data:
2.1 Fuel Parameters:
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 of 5mm to 300mm. Good
quality pellets have a density which varies between
600kg/m3and 750kg/m3, with a moisture content which
varies from 5% to 8% by weight.
Besides being 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 4.4kW/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 10kg bags, so sorting 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 in pellets in the European
market is Enplus-A1 and 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 of
biologically decomposing material.
T R Engineering Ltd recommends using certified fuel in it
appliances to Enplus-A1. The use of fuel of inferior quality or
not conforming to the specification given above compromises
the running of the guarantee and of the manufacturer’s
responsibility for the product.
T R engineering Ltd’s domestic pellet appliances run
exclusively on pellets with a diameter of 6mm.
2.2 Connection of the Flue:
A full range of straight, offset, elbow and ‘T’ elements are
available to overcome any obstruction which the flue should
avoid. 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 pressure 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° changes in 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 BE AND NOT MORE
THAN THREE 90° ELBOWS (INCLUDING ‘T’s). IT IS ALSO
ADVISABLE NOT TO EXCEED 8 METRES IN LENGTH WITH THE
PIPE OF 150mm DIAMETER.
The flue connection on the boiler is 146mm. T R Engineering
Ltd recommends the use of 150mm diameter flue for use
with this appliance.

The above drawings show the main boiler elements. They
have the following specifications:
Burner –made out of fireproof steel. Its geometry is
result of numerous tests and measures. Equipped with
air intakes on various levels which contribute to
increased combustion efficiency. Biomass is transported
from the hopper to the burner by means of the auger
feed. On contact with embers and in connection with air
supplied by many ducts the process of pyrolisis of
biomass occurs. Exhaust fumes created in the process
are directed through the heat exchanger to the chimney
outlet through the chimney duct which is enhanced by a
fan, which also serves a role of providing a sufficient
amount of fresh air for proper combustion. The amount
of fuel and fresh air supplied for combustion is
automatically matched by the controller based on
exhaust fume measurements (oxygen content in exhaust
fumes) provided by the Lambda probe.
Combustion chamber –made out of fireproof steel.
From the moment of starting the ignition process it
quickly gains high temperature, which in turn improves
the combustion process and reduces the amount of un-
burnt gas. It is also isolated between the flame and
boiler wall.
Revolving hatch –it is a factory assembled element.
Ensures perfect tightness between the hopper and auger
feed. Guarantees very precise dosage of pellets.
Ignitor –allows for completely automatic ignition of
pellets is controlled by the PCB.
Turbulator (turbulators) –designed to increase the
effectiveness of heat exchange by momentarily slowing
down the speed of the exhaust flow. Additionally, they
are periodically, automatically put in motion by this and
the heat exchanger is cleared of ash. Releasing the user
from performing the task.
Automatic heat exchanger cleaning system (turbulators
drive) –a reduction unit controlled by automatics of the
boiler, that propels the turbulators.
Exhaust Outlet –contains a box that can be removed to
gain access to the boiler. On top of the box there is an
exhaust outlet and a turbine, responsible for the
extraction of exhaust towards the chimney. The electric
motor that is driving the turbine is controlled by a
microchip via a voltage regulator, which provides
voltage based on the measurements provided by the
Lambda probe. This solution has been used for many
years. Bottom combustion has a lot of benefits, and also
prevents the fire getting to the pellet hopper.
Auger feed –worm-gear that works in a sequential
pattern depending on the demand of the burner. The
auger provides a small amount of fuel that is released by
the hatch. This allows operation under minimal load.
The decantation chamber –expanding area located
underneath the heat exchanger allows the deposition of
unburned particles and dust hovering due to lower
exhaust fume speed.
Ash pan –located under the burner. Collects ash that is
removed from the burner, ash that drops by force of
gravity, and also ashes that origin from automatic heat
exchanger cleaning.
Automatic removal of ash from fireplace –occurs by the
supplied pellet, and also by fresh air flowing through the
burner.
Lambda probe –located in the exhaust outlet. The
purpose of the Lambda probe is to control the content of
oxygen in the exhaust. Using the measurements it allows
the optimisation of the combustion process used for fuel.
In combination with the temperature probe it guarantees
correct boiler operation, and doubles as a safety device.
Exhaust probe –pilots the ignition and also manages the
power of the boiler. Another role is to protect the boiler
from unforeseen temperature raise.
Display –located on the front of the boiler. Allows
browsing through and editing of the available control
parameters.
Electronics cover –covers the electric box that houses the
heart of the control circuit.
Pellet hopper –its capacity depends on the power of the
boiler. Theres also the possibility to connect it to an
external feeder, which supplies fuel from a repository or
large silo.

3. Setting Up and Installation of the Boiler:
3.1 Engineers Responsibility:
The installation of the boiler can only be performed by
qualified biomass engineers, complying with, and in line with
all rules, regulations and norms. The installer must also
comply with all recommendations, and directions provided
by the boiler manufacturer. Specifically this applies to the
instruction manual, boiler fitting method and its components
and also all hydraulic systems.
For any discrepancies, inconvenience, damage and injuries
that result from non-complying with regulations and
recommendations found in this manual the installer takes
the full responsibility.
3.2 Boiler Room:
Pellet boilers should be fitted in a specifically allocated room
(boiler room). The fuel deposit should also be located in an
allocated room near the boiler, however, not closer than
400mm from the boiler. To ease access to the boiler and to
enable maintenance, there should be at least 400mm of free
space around the boiler. The boiler should be positioned on
a non-combustible, thermally isolated base, which the
dimensions should exceed the dimensions of the boiler by at
least 200mm on all sides. If the device should be mounted in
a basement it is advisable to put it on at least a 50mm height
foundation.
It is mandatory to check if the boiler is perfectly horizontal,
and level to prevent air pockets from creating.
During the installation of the boiler it is advisable to provide
sufficient distance from inflammable materials, according to
the level of flammability.
If the level of flammability of material near the boiler is
unknown, the safe distance should be doubled (safe distance
is 200mm).
A permanent air entry air entry opening or openings with a
total free area of at least 550mm2per kW of appliance rated
output above 5kW.
It is mandatory to fully follow all instructions and
recommendations regarding boiler room contained in this
instruction manual as well as in norms and regulations.
In case the boiler and its equipment is to be fitted in an
open space, where the temperature might drop below
15°C, or if the furnace might be subjected to conditions that
might be destructive to the device or any of the additional
equipment, such as presence of chlorine, acids or overly
humid air, the manufacturer is released from obligation to
provide warranty support for any part of the boiler, as well
as additional equipment. All doubts regarding the boiler
room should be directed to the manufacturer.
3.3 Ventilation and Exhaust –Chimney
System
Proper combustion also requires a proper exhaust chimney
system. The role of the chimney is to pipe away exhaust
fumes. The chimney required to complete this depends on:
Temperature difference between exhaust and surrounding
air;
Usable chimney height;
Diameter of chimney (no less than flue spigot diameter);
Chimney workmanship –as smooth as possible inner
surfaces an air tightness;
Usable chimney height is the difference between the highest
point of the fireplace and chimney outlet. This value should be
at least 4m for individual chimneys. In case of sloping roofs,
chimneys should end around the crest, in the area of smooth
wind flow –this way there’s no interruption of air draught. It is
always necessary to take into account the location and
orientation of the building in relation to surrounding buildings.
In most cases, to determine chimney parameters it is enough
to use the approximation method, or diagrams would not be
sufficient to determine an exhaust system. Chimney
parameters should be calculated according to regulations.
The cross-sectional area of the chimney should be 160 x
160mm. Improper cross-sectional area selection may cause
slowdown of exhaust fumes and in turn, deposition of ash
inside the chimney. If exhaust temperatures would drop below
the dew point, the water vapours and sulphuric acid might
cause damage to the wall.
The connection of the boiler and chimney should be made by
flue. They can be made as exhaust pipes, or exhaust channels.
Exhaust pipes are pipes or forms, which assembled inside
room. Exhaust channels usually comply with the fire
regulations for chimneys and are made of the same material
that the main chimney is made of. The connection between
the boiler and chimney should be as short as possible, and
assembled in a raising manner to reduce heat loss and
additional resistance. They cannot be guided to different
floors. Exhaust pipes shouldn’t be mounted in rooms where
fireplaces cannot be located and shouldn’t be placed in walls
and ceilings.
3.4 Hydraulic and Electrical Schematics:
Pellet boilers must be installed according to valid rules and
regulations by the authorised installation company. First start-
up must be performed by a service trained engineer and
authorised by T R Engineering Ltd that can show legitimate
validation document. The responsibility for proper boiler
installation and repairs is held by the installation/servicing
company, trained by the manufacturer, and that has
validation/authorisation. Any manipulation or changes made in
electrical parts of the boiler, or connecting additional
controller devices, might result in warranty loss.
Finalisation and test heating must be denoted on the boiler
warranty card. Lack of such information about start-up in
warranty card might result in warranty loss.
Hydraulic system should comply with BS 7593 and BS 5449 and
be executed according to building regulations.

Plug Connection of Water Mixer:
A blending valve can be used for back end protection. This
is controlled by the connections above.
Requirements regarding water that is in central heating
circuits are the following:
Water must be clean and treated to BS 7593;
Hardness of water below 20°F;
PH below 8.5
The boiler is dedicated to following electrical parameters
230V/50Hz. Electrical systems should be executed by a
qualified person that will create a 230V/10A double pole
isolator, in an easily accessible place. Electrical supply of the
boiler and lighting should be connected to separate circuits.
3.5 Boiler Start-up by the User
The programmer is a modern microprocessor system which
controls not only the boiler, but also the central heating
system and Domestic hot water.
The unit controls the amount of fuel fed through the auger,
and the air supplied to the combustion process. Thanks to
solid stat relays (SSRs), the fan has variable speed control
and the reliability of the unit controlling the auger motor is
greatly increased.
Automatic fuel ignition –The control unit provides
automatic fuel ignition.
Measurement of waste gas temperature –The control unit
measures waste gas temperature which is an essential
parameter in a boiler with automatic start-up. Waste gas
temperature readouts are also very useful when inspecting
the boiler and adjusting its operation.
Large alphanumeric display –facilitates communication
between the unit and the user.
Lambda sensor –ensures optimum supply of air to the
combustion process, thereby simplifying the work of the
operator; it also reduces fuel consumption and improves
combustion, reducing emissions of harmful substances to the
environment.
Pneumatic fuel feeding control system –allows the boiler to
operate for long periods of time without the need to add
fuel.
Heat exchanger cleaning control system –ensures that the
boiler retains high efficiency without the need to clean the
exchanger.
Thanks to advanced operation algorithm and the possibility of
controlling numerous parameters, the unit can be flexibly
adjusted to the needs of the heating system.
The controller has an output testing function. The function is
available in the MAINTENANCE MODE and checks the
correctness of electrical connections and the working order of
the controlled equipment (pumps, fan, auger, mixing valve
actuator) prior to starting the boiler.

3.5.2 Amount of air, Lambda sensor –
Power Test Mode:
The combustion process requires the supply of air, the
amount of which depends on the type of fuel and the power
of the heating unit. Therefore, the optional amount of air
should be set for each type of fuel and each burner power
level. This should be down by the person who starts up the
control unit. The parameters are saved in the non-volatile
memory of the control unit. In order to set the optimal
amount of air, you should:
Set the type of fuel corresponding to the fuel to be used,
Turn on the control unit,
Enter the POWER TEST submenu and run the “power
test mode”,
Set the amount of air for 20, 40, 60, 80 and 100% of the
burner power. The values will be calculated by
approximation method from the selected curves. See
figure 6.
If the control system includes the optional Lambda module,
oxygen values should be set in a similar fashion for the
various burner power levels. The parameters should be set in
line with the boiler manufacturer’s specifications, or on the
basis of the results of waste gas analysis at the different
burner power levels.
If the fan power is controlled using the Lambda sensor
module, the fan power may be adjusted within the range ±10
adjustment units. This relationship is shown in Figure 7.
NOTE!!! Turn off the chimney sweep mode once you have
completed the adjustments.
When adjustments are made in the power test mode,
automatic burner power control is deactivated so as to allow
measurements and analyses at constant burner power.
Figure 5: Power Test submenu
3.5.3 Air during Ignition:
The amount of required air for ignition is set separately because
it differs from the amount of air during normal operation of the
burner.
Air amount during ignition is set using the “bl.ignites” parameter
in the service “SERVICE MODE” submenu. See table on page 16.
3.5.4 Pumps:
In order to be efficient and last long, the boiler must operate
within a certain temperature range. This is why the circulation
pumps should only run when the temperature exceeds a certain
minimum level. The “min. pumps temp” parameter is available in
the “SERVICE MODE” submenu. This should be set to 50°C.
3.6 Menu Language:
The menu of the control unit is available in a number of
languages: Polish, English, German and French. The preferred
language may be selected in the “language” submenu. The
default setting is English.

ON –the control unit is on.
NOTE!!! When off is displayed on the screen, the control unit
is actually in a standby mode and is energised; in case of an
alarm, the control unit will initiate the appropriate remedial
actions (i.e. it will either turn on the pumps or the auger).
If you intend to not use the boiler for a considerable period
of time, or to do any maintenance on the boiler, you must
de-energise the control unit by isolating the power supply.
The display (main screen) shows the current status of the
different pieces of equipment.
Boilers with the M RS 240M control unit are ideal for
domestic hot water both in the heating season and in other
parts of the year.
Both sensors supplied with the unit, should be installed in
the buffer tank and the following settings should be set up.

After you press the button, the auger will run for 30 seconds,
filling the burner with pellets about half way. Once this happens,
turn the boiler control unit ON; the fuel will ignite automatically.
3.6.3 Alarms and Safeguards:
The flashing of the display screen of the control unit is an alarm
signal. Press “ENTER” to display information about the alarm.
The control unit activates the following types of alarms:
Boiler overheating; alarm is activated when the boiler
temperature exceeds the “Talarm boiler” which may be set
in the “service mode”. When this happens, the control unit
on the circulation pumps and keeps them running until the
boiler temperature drops, regardless of the operating modes
selected.
NOTE!!! The circulation pumps will be turned on and will run in
pre-alarm mode when the temperature rises to 2°C less than the
boiler alarm temperature. If the temperature does not rise above
the alarm level, information on the incident will not be saved in
the control unit’s memory.
No flame/no fuel; the alarm is activated if the suction
system has made three consecutive failed attempts to ignite
the fuel.
NOTE!!! Once an alarm has been activated you should determine
and eliminate its cause.
The independent thermal boiler protection (ITBP); is
dependent of the microprocessor system. An independent
thermal switch will cut off the power supply to the fan if the
boiler temperature exceeds 94°C.
