How your 'S' Model Wood Pellet Boiler Operates
The 'S' Model 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 :
Run Mode
Standby / Extinguishing
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
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.

Pre-Installation Considerations
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 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 will intervention 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 are
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.

All domestic pellet appliances run exclusively on pellets with a diameter of 6 mm
The 'S' Model boiler has been recommended as suitable for use in smoke control
areas when burning Enplus-A1 wood pellets
Installation and assembly of the appliance must be carried out by suitably trained 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 connecting to 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.
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 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
E-Compact 'S'
Pre-Installation Considerations

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 vents 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 vents 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
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

The manufacturer 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.
All 90 degree changes of direction in the flue pipe
must be either removable or capable of inspection.
The manufacturer recommends the use of 100mm Therminox flue for use with this
Pre-Installation Considerations

Page 14
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.
E.g. Downdraft at 45° of
8m/sec. Overpressure of
17 Pa
E.g. Crosswind 2 :
8m/sec. Depression of
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).
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
personnel certified by the manufacturer.
Pre-Installation Considerations
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
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.
The manufacturer 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,

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 'S' Model pellet boiler should be positioned on a concrete plinth at least 50mm high and
should project a min. 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
pipework and electrical supply.

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 Technical Support or your Local Dealer for
guidance before carrying out any connections.
The 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.

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
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 manufacturers
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 pipework 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 pipework 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.

Once the plumbing has been completed the system should be fully flushed to clear any debris
which may have become lodged in the pipework. 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

External control of the boiler
• 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.
This boiler is controlled by a sophisticated control system employing
fuzzy logic ensuring the boiler runs at optimum efficiency .
To control the boiler touch screen control panel located on the front
panel of the boiler above the combustion door.
The touch screen control panel operates in a similar fashion to a smart phone or tablet using
touch to navigate through the different screens and menus.

Boiler Operation & Maintenance

The Boiler 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.
Emptying the Ash Pan
• The boiler contains an ash area where ash needs to be removed at regular intervals.
• The ash pan is located in below the main combustion chamber. The frequency of
emptying the ash pan is determined by the quantity of fuel burnt and after 250kg
the controller will display a warning to empty the ash pan. A daily check during the
first few days of operation will give an indication as to when it needs to be emptied.
Unscrew the two fixing
knobs on the ash pan.
Remove the ash pan
and discard ashes.
Always make sure that before you open the ash pan the boiler has
been switched off and 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.

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.
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 not to cause injury.

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.
• Set the controller hopper level to 100%
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
