SECTION 1

Planning requirements.
If you are thinking of making any changes to your property, including installing a
form of renewable energy, you must apply to the Building Control Office at your
local council for approval.
Planning permission may or may not be required, depending on such factors as:
location, individual planning department, nature of scheme, neighbors' opinions,
visual impact and proximity to public through roads.
Before beginning any work we recommend that you contact your local planning
department to determine whether planning permission is required.
uilding regulations.
- Any installation of a heating appliance, or modification to a chimney such as
relining, has to be carried out in accordance with. Building Regulations – Republic
of Ireland Part F – Ventilation Part J – Heat Producing Appliances (Article 1 in
N.Ireland Part J in England and Wales and F in Scotland). Building Control
Consent might also be needed for such work unless the work is carried out by a
qualified person as stated below. We recommend that all installation or design is
completed in accordance with British Standards, including BS 5 10 , BS 5 3, BS
876, BS 1181 and BS 715.
Installer expertise.
All installation work should be undertaken by a person who is a member of an
approved competent person scheme as outlined in the COMPETENT PERSON
SELF-CERTIFICATION SCHEMES IN 2003 which can be found at.
http://www.odpm.gov.uk/index.asp?id=1131139
All appliances must be commissioned and failure to do so will
invalidate the
boiler/burner warranty.

Section 3
Assembly.
Fitting the burner unit.
1. seal with fire rope or heat resistant gasket sealer to the boiler via the
square hole located on side of boiler (left or right depending on
requirement).
2. mount the burner unit into flange and secure locking bolts
Fitting the feed screw.
1. fit one end of the thermoplastic hose to the top of the inlet tube on the
burner unit, and the other end of the thermoplastic hose to the outlet of
the feed screw.
2. mount the feed screw over the burner so the pellets can fall into the
burner effortlessly. The more the feed screw is mounted at an incline, the
less pellets it releases.
- adjust the control system according to the angle of incline. (see section 5,
operating the burner)
3. ensure the thermoplastic hose is angled enough so the pellets end up in
the burner, shorten the hose if needed.

Pellet silo assembly.
The pellet silo…..
As the pellets that you put into the silo contain dust, you should empty the silo
completely from time to time. The more dust that is in the silo, the less pellets
the feed screw will release and the boiler will become unadjusted, leading to
inefficiency and possible breakdown.
How often the silo needs emptying completely, depends on the design of the silo
and the quality of the pellet fuel used.

Section 4
Installation.
Power supply and connection.
230 volts 50Hz 10 Amp 60 Watts
Control is supplied via a priming circuit breaker,(high limit safety cutout stat)
which is mounted on the rear of the boiler (item , page 3). The temperature
sensor is mounted in the same immersion pocket as the priming circuit breaker or
a suitable place where the boiler temperature can be measured. Mount the power
to the control system via the priming circuit breaker so that the power is broken if
the temperature of the boiler exceeds 95 degrees in the event of a fault.
Flue pipe and chimney connections.
Use the correct flue size for boiler model (table 1, page 3).
Ensure adequate height of chimney to gain satisfactory draw and to prevent back
draft. A suitable cowl/rain cap/anti back draft must be fitted.
We recommend that a draft stabilizer is always mounted to the chimney.
The vent pipe should not be greater than 1 metre in length and should be
equipped with an access door.
The flue pressure of the chimney should be a minimum of 10 PA and be stable. A
flue fan may be required to assist the draft and secure stability.
Upon condensation of flue gases in the flue, a condensation trap should be
installed, or the valve in the rear flue of the boiler be opened, so that the flue gas
temperature is increased.

Section 5
Starting the unit for the first time.
1. check all connections on burner, boiler, feed screw, flue, chimney and
power supply.
2. ensure that there are pellets at the inlet of the feed screw in the pellet
silo.
3. activate the forced feed operation by pressing the UP button on the
controller for 10 seconds and turn the mains power on at the same time.
4. when the feed screw has filled with pellets and they are falling into the
burner, turn the power off at mains.
5. The burner is started by switching the mains power on again. The control
box can be started/stopped by pressing the on/off button for 8 seconds.
6. The alarm is cancelled by pressing the DOWN button 2 times within 8
seconds.
To obtain the optimum efficiency from the burner and boiler, correct
adjustment is essential.
Please refer to section 5 on adjusting the burner and section 6 on
cleaning the burner.
Adjusting the burner.
For first time start up, refer to quick start guide on page 15.
The outputs for high and low loads are run by the control system in a 100 step
modulation and the changes between the different steps are made automatically.
Feed adjustments for high and low loads.
Wood pellets can vary (dust, pellet length etc.) so correct adjustment for fuel
economy and boiler efficiency are essential. The feed screw will supply the pellets
differently and will have an influence on the burn quality. It is necessary to open
the doors to the burner and look at the flame.
If the flame is fat – dark, possibly with black points, or the ash is black with
black pellets, fewer pellets are needed. Reduce steps 2 and 3 in the main menu.
If the flame is thin – little flame and like a sparkler, or the ash is light grey,
more pellets are needed. Increase steps 2 and 3 in the main menu.
* Correct burning adjustments normally produce a dark grey ash. *
The burner is intended for wood pellets between 6-8mm diameter.
If you are in any doubt then subscribe to a service contract. For further

Main menu on controller.
In order to adjust the burner press the SET button on the controller and
you will gain access to the main menu use
There are four adjustment options in this main menu.
1. oiler temperature: *factory settings 60 degrees*
press the UP or DOWN buttons to reach the required
water temperature.
2. Feed screw in low load: * factory settings 5.6 *
press the UP or DOWN buttons to adjust the quantity
of pellets that corresponds to the blower speed. It is
important that this adjustment is correct in relation to
the speed of the blower. In the event of an incorrect
adjustment, the boiler will not run as economically and
there will also be the risk of a breakdown.
3. Feed screw in high load: * factory settings 33.6*
press the UP or DOWN buttons to adjust the quantity
of pellets that corresponds to the blower speed. It is
important that this adjustment is correct in relation to
the speed of the blower. In the event of an incorrect
adjustment, the boiler will not run as economically and
there will also be the risk of a breakdown.
4. Feed screw in pause firing: * factory settings 16.0*
pause firing enables the burner to keep lit and not to
have to use the electronic ignition every time more pellets
are required. Press the UP or DOWN buttons to adjust
the quantity of pellets the burner will use during pause
firing. Set as low as possible without the burner going out.
The burner fires every 5 minutes.
