CONTENTS IMPORTANT INFORMATION
GENERAL INFORMATION
BeQuem 50 is a reliable and easy-to-use pellet burner. Its sturdy heat-resistant cast
iron components ensure a long service life and minimise maintenance costs. Detailed
technical data are presented on page 3. To make use of all features of the burner, it is
important to observe these instructions.
IMPORTANT
Keep this manual in a safe place for future reference. Read this manual carefully be-
fore starting to use your BeQuem 50 pellet burner. e output of the pellet burner
depends on how much pellets can be fed into and burned in the combustion head du-
ring one hour. (is means burning of pellets of the usual kind, which approximately
comply with the fuel specications described in this manual).
NOTE! The protective hood on top of the burner must not be removed, unless the device has been
disconnected from electricity supply. Follow the recommendations for the use and maintenance of
the burner contained in this manual.
SHIPMENT, STORAGE AND UNPACKING
Delivery
e manufacturer has insured the burner in case of damages during transport from
the factory to the rst interim storage location. Upon delivery it is important to check
the condition of the burner before the burner is taken into use. If any damage is found,
the seller shall be notied thereof without delay for possible claims.
Storage
e burner can be stored outdoors protected from rain for a short period of time. Ho-
wever, it is advisable to store the burner indoors.
Disposal of the package
e transport cardboard box can be recycled.
FUNCTIONAL DESCRIPTION
Heating with the BeQuem 50 pellet burner resembles in many ways oil heating. e
greatest dierence is that when heated with solid fuel a certain amount of ash is produ-
ced, which must be removed periodically. Otherwise, the eciency of the burner will be
reduced.

OPERATING PRINCIPLE SAFETY AND ALARMS
For safety reasons the pellet heating centre and the fuel storage must be placed apart
from each other to prevent possible accidents: any operation disturbances and dama-
ges caused by incorrect handling of the device will then be limited to the burner. e
fuel storage must be built as a separate, re-classied, conned space.
Problems caused by faulty stopping of the system are indicated by a red light on the control
panel. In addition, a text message appears on the display indicating what has caused the
alarm.
During every operating cycle, a small amount of pellets (approx. 150 g) is fed from the
pellet storage via the external feeding system to the upper connection of the burner. To
make it possible to dose an accurate and same amount of pellets during every cycle, the
dosing is carried out by means of a separate dosing auger via the blocking feeder and
burner auger to the combustion head.
Because the burner auger feeds pellets forward three times faster compared with the speed
at which pellets arrive at the auger, a safety zone is formed between the combustion head
and the upper connection containing only single pellets. Even if a mains outage would oc-
cur in the system, the equipment had not been maintained correctly, or some of the parts of
the equipment would have broken down, this safety zone will remain intact.

e BeQuem pellet burner is provided with automatic ignition, but it can be ignited
manually, when necessary. e electric ignition system of the burner will only be acti-
vated in case the temperature of the boiler has dropped at least 8°C below the target
temperature. During heating, the necessary ignition cycles take place by means of em-
bers in the combustion head, saving electric energy.
e burner and the incorporated feeding system operate automatically. e opera-
tion of the burner is controlled by a temperature sensor installed in the burner. e
combustion head of the burner contains an accurately dened mixture of fuel and air,
which ensures perfect combustion cost-eectively and environmentally friendly.
e burner auger is over-pressurized during operation. e purpose of this is to redu-
ce the risk of damage to the burner, e.g. if the draft through the burner is weak.
Wooden pellets with a diameter of 8 millimetres are the recommended fuel for the
burner.
COMPATIBILITY OF THE BURNER AND THE BOILER
e pellet burner can be installed in boilers, which meet certain requirements as re-
gards the size of furnace, sucient under-pressure and ash space.
Required furnace size: Depth at least 430 mm measured form the insertion opening.
Free height above the combustion head at least 350 mm to guarantee a suciently lar-
ge combustion space for the ame.
e boiler must have a suciently large ash space under the combustion head so that
the ash removal interval is suciently long from the maintenance point of view and to
ensure good operational reliability of the burner. Ash removal should be performed
through a separate hatch to avoid the need to remove the burner for this task.
In the furnace there must be a sucient under-pressure, (“natural draft”), which allows
burning of the pellets eciently. As a guide value approx. 30 Pascal is suitable.

INSTALLATION
Good planning saves time. Ensure immediately upon delivery from Ariterm that eve-
rything is included and undamaged. If possible plan in advance for on-site assembly.
Any required adaptation of the complete docking plate is easier to do on site (home)
than in a workshop.
e boiler must use natural ventilation and have ample space above the combus-
•
tion chamber or at least 300 mm. Exeption is possible in a number of boilers, but
often in combination with a marginal reduction in eciency. Always contact us
for advice when unable to achieve the recommended measurements.
e door opening must be at least 230 mm high and 225mm wide.
•
e chimney must always be inspected at installation for airtightness, draught
•
and risk of condensation. Draught regulators and insert tubes may need to be
instaled. e recommended draught is 30 Pa.
Boilers should always be installed so that variations in draught conditions do not
•
aect boiler performance. is can be accomplished with devices such as instal-
ling a draught regulator.
Space needed for installation: e open space in front of the boiler (including
•
burner) must be at least 1,0 m, in order to facilitate usage and burner servicing.
Any condensation should be checked by visual inspection of the chimney’s
•
upper reach during various weather conditions. In the event condensation runs
through the ue, a condensation vessel should be installed in the lower part of the
chimney in order to tap o the condensation water.
Do not cover the combustion air intake.
•
ELECTRICAL INSTALLATION
e supply cable delivered with burner is connected to the burner. In addition, an
over-temperature protection thermostat must be installed in the boiler (this must
acquired separately). e connection is made in accordance with the wiring diagram
annexed to this manual. Also the use of a safety switch (burner switch) is recommen-
ded. e other connection cable delivered with the burner is for boiler temperature
and ue gas sensors. Work on the burner may only be carried out by a qualied servi-
ceman. Make sure to cut the power supply to the burner before servicing.
COMMISSIONING
Before starting up the boiler, check the following:
e heating pipework and the boiler are lled with water and the pressure is at •
least 0.5 bar.
e possible ue gas damper has been opened•
e recirculation damper in the convection part of the boiler is in place•
e circulation pump is running•
e valves in the heating pipework have been opened•
e combustion air opening has been opened•
e safety valve is connected without obstructions to the boiler and is in good •
operational condition.

MOUNTING OF DOCKNING PLATE AND SERVICE RAIL
Mount the secondary air tube, service rail and quick-release hand hold as shown in the photo-
graph.
Use the door frame as a template for drilling the four holes for the boiler’s
stud bolts in the docking plate. In some cases, the docking plate’s outer di-
mension must be adapted to t the boiler. It is easiest to use a circular saw.
Mount the plate against the boiler frame with heat-resistence glass bre
reinforced sealing strip or furnace cement, which can easily be applied
afterwards through the mounting plate opening. Tighten while making sure
the plate is not deformed. Final tightening of the service rail is to be done
only once the burner has been attached and secured to the mounting plate.
The service rail is to be pressed up against the boilers guide pins and outer
clamping bolts are to be securely tightened. Check that the burner is cent-
red on the mounting plate’s guide pins when it is pulled out and pushed in.
It is a good idea to lubricate the guide arms.

START-UP IN OFF MODE
Cold start of the burner (with electric ignition)
Cold start of the burner takes place after the burner has been switched o at the cont-
rol panel, a fault has occurred in the operation of the burner, or the mains voltage re-
turns after a mains outage. e temperature of the boiler must be at least 8°C below
the set value. Otherwise, the automatic control unit supposes that the burner is in the
hot start mode and does not use the ignition resistor at all.
If the external feeding system is empty of pellets, it must be relled before swit-•
ching on the burner. Switch on the control unit of the burner at the main switch
so that the red light turns on. Press the arrow button to the right. e operation
display of the burner must be OFF. Browse menu 1 by means of the arrow button
forward, until the message “AUGER EXTERNAL MANUAL OFF” is displayed.
Switch on the external auger by pressing the Plus button. When the auger is ro-
tating, the remaining running time is indicated on the display. e external auger
can be stopped before the set time elapses by pressing the Minus button before
the drop tube begins to be lled with pellets.
To switch on the burner, go forward to menu 1 by means of the arrow button, until •
OFF (+ON) appears on the display. Select ON by means of the Plus button. en
the burner motors starts, the burner gets fuel to be fed to the combustion head via the
feed auger, and after 3 minutes also the fan and ignition resistor will be switched
on.
e optical sensor of the burner detects the moment when fuel has been ignited •
and switches o the ignition resistor. At the same time, the operation light turns
green and the speed of the fan decreases. Feeding of fuel stops completely within
three minutes in order to give time for the fuel to ignite in the combustion head.
After this pellets are fed at low power for further ve minutes. After a full stop
lasting ten minutes (7 starts), the operation program switches on and controls the
burner functions. Only until at this point the burner switches to the normal hea-
ting mode. In case the ignition fails, the red light will come on again and an alarm
message appears on the display.
e maximum amount of cold start cycles is seven. e proceeding of these cycles can
be followed on the display by selecting the menu option “Operating mode”. Don’t make
any adjustments on the burner or similar measures during the ignition cycle.
Note! When the burner is switched on at the first time or, for some reason, it does not contain any pellets, a
restart is sometimes required approx. after a 3 minutes’ running time.
START-UP IN OPERATING MODE
Hot start and switching off
A green light indicates that the burner is in operating mode. During operation, the
temperature sensor of the boiler controls the start and stop functions of the burner.
When the temperature of the boiler has dropped 5°C below the selected set value, the
burner switches to medium power. If the temperature drops by further two degrees,
the burner starts to operate at maximum power. e burner operates at maximum
power, until the temperature has dropped four degrees below the set value, after which
the burner starts to operate at medium power again. e red light indicates that the
device has been switched o.
(see “Troubleshooting” ).
Switching off
To switch o the burner, select the menu “ON (OFF)”. Select OFF by means of the
Minus button. When the burner is in OFF mode, a red light is illuminated on the
control panel indicating that the power has been switched on.

SETTINGS
Adjusting combustion
e boiler is delivered with factory settings, which in most cases are sucient for
proper, ecient combustion. e boiler’s factory settings can be applied if negative
pressure is 30 Pascal (Pa) in the ue. If combustion is poor anyway and the ue gases
from the chimney are black or the ash is grainy, combustion can be adjusted to attain
the desired end results. Adjustment is made with a ue gas analyser and should be
carried out by a service technician authorised by Ariterm. Flue gas analysis shall be
shown for carbon monoxide (CO) values under 200 ppm and excess air (O2) 6-8%.
e fan’s air quantity and the feed percentage for the burner screw is adjusted in the
following manner.
e amount of pellets in the burner cup is set in the output menu by changing the
percent gure for POWER HIGH AUGER and POWER LOW AUGER.
e amount of air is set in the output menu by changing the percent gure for PO-
WER HIGH FAN 1 and 2 and POWER LOW FAN 1 and 2.
