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
wood 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/m3and 750kg/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 4.4kW/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 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 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 there ensure respect of:
Calorific power: 4.9kW/kg
Water content: max 10% 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.
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

Greenflame Wood Pellet Boiler 15kW

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.
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 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.
3.3 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 40m3/h must be available),
as laid down in the standard governing the installation and in
accordance with local national standards. All louvers 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 flammable, position the appliance with a
clearance to the rear of at least 45cm. For flammable walls,
keep a minimum distance of 450mm at the rear, 300mm on
the sides and 1500mm 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
3.4 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 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 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.
900mm
600mm
600mm
1200mm

Greenflame Wood Pellet Boiler 15kW

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 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 Ø 80mm.
The flue connection on the boiler is 80mm. T R Engineering
Ltd recommends the use of 100mm flue for use with this
appliance, so a 80mm to 100mm adaptor is needed.
3.5 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 up draught always increases depression and
hence draught. A crosswind 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 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 I 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 noticeable 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 T R
Engineering Ltd personnel.

3.6 Plumbing Connection
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 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.

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 of 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 6.

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

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 expansion vessel 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 metres) 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 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 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.
If a buffer probe is being used to control the boiler then no
other external controls can be used and P35 should set to 5
in the system menu under default settings.
If the system is a Y plan or S plan and external controls will
be used to control the boiler then P35 should be set to 1.

6. Boiler Operation & Maintenance
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 quite simple
from a regular inspection of the combustion chamber to
remove ash to filling the hopper with pellets.
6.1 Turning the Boiler ON/OFF
It is recommended that your boiler is controlled 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.
If a buffer sensor is being used to control the boiler then no
other external controls can be used.
6.2 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 but 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.
Error codes must be notified to
the service personnel in order
to diagnose the problem.
Always allow boiler to cool
down before opening the
combustion chamber door.

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.
7. Boiler Handling
One of the key features of the Greenflame 15 is its size and
ability to be transported to and located in confined spaces.
Care should also be exercised when manoeuvring the
appliance into position. The illustration below indicates the
weight distribution of the appliance.
Always protect the appliance when transporting on trolleys
or hand carts.
Only persons who have been trained in manual handling
techniques should attempt to move the appliance.
Incorrect lifting techniques can cause serious injury.
Unscrew locking nuts
Carefully remove secondary
ash pan and dispose of ash
into a metal container.
6.3 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.
