efficiency for a long period.
Due to the continuous development in methods, design and manufacture, the contents of this document may
change at any time and without prior notice. Manufacturer does not accept any responsibility for errors or damage
of any kind that is attributed to this publication.
2. WARNINGS
These safety guidelines should be read and fully understood before the first operation of the system, to
avoid incorrect usage that might lead to personal injury or damage to the system.
This boiler must be installed in accordance with the local and international rules in force, only in a well
ventilated and frost free spaces, indoor but other then living areas.
All installation, assembly and maintenance, repair, replacement of components work must be carried
out exclusively by fully trained, professionally qualified personnel and must conform with this manual and the local
codes and requirements of the authority having jurisdiction, or in the absence of such requirements, apply to the
EEC directives and European (EN) and local norms.
If the boiler is not used for the purposes other then specified in this booklet and incorrect installation,
commissioning and use, can cause a fire or explosion which may result property damage, personnel injury, or loss
of life.
Boiler is designed for hot water operation only (max 90 ⁰C) and the system pressure must be according
to the limited operating pressure specified on the boiler name plate and in this booklet. Heat transfer medium is
water.
Boilers must be fired by fuels specified in this manual (8.2).
This is a B23 appliance so the flue gases must be connected to an adequate draught chimney, without
any flue gas leakage to the boiler room.
It is essential that an appropriate pump is fitted in the circulation system which must be kept in operation
at all the times when the boiler in use.
The filling and make up water must be according to the specifications given in this manual. Long term
water treatment is essential to the economic operation and life of both new and refurbished heating systems.
Never obstruct the ventilation openings to the boiler room for a safe and efficient operation. An
adequate air supply for combustion and ventilation must be provided at all times.
Boilers must not be installed in areas where inflammable vapors and materials are likely to present. To
avoid damage to the boilers, contamination of the combustion air by high levels of dust or halogenated
hydrocarbons (e.g. Solvents, spray can propellants, cleaning agents, adhesives, ect.) must be avoided. The
humidity level must not be high in boiler rooms.
The boiler room must not be used for other purposes and must not have an open connection to the
other closed living areas. Connection door must be air tight, fire resistant and self closing.
All the control devices must be functional and operating with in the limits specified at all the time. If any
of them is null functioning do not operate the system and call a qualified service.
If the boiler is heated above 90 °C, do not supply cold water to the system for rapid cool down. It can
cause an explosion. Wait the boiler cool down naturally up to 40 °C before any operation.
Do not use this appliance if any part has been under water. Immediately call a qualified service to
inspect.
Do not touch the flue gas exit and flue box. These areas are too hot and can cause serious injuries.
In starting a new installation, first commissioning shall be performed by a qualified service.

- 4 -
After commissioning repair and maintenance work is under responsibility of user and must be performed
by a qualified service.
If you want to change the fuel type in the future please call your authorized service. The fuel type
change can need some part or device changes and surely new adjustments. Never try to change the fuel type by
yourself or by unauthorized people.
Except the operations specified in this manual, do not touch any part of boiler for adjusting or
maintenance.
This boiler is not a condensing type, so be sure that the boiler must not condensate for long periods
Covers on electrical components may only be removed if the power has been disconnected.
Never open the bottom drawer while the boiler is in operation, as hot flue gases, flame and red hot dust
particles can cause explosions and might cause serious injuries.
Switch off the system before servicing and chimney sweeping. The system must be allowed to cool
down before the cabinet door is opened. Wait around 20 minutes, or until the boiler temperature on the display is
under 40 ⁰C
Flammable liquids or gases must never be used in the combustion chamber.
It is recommended that you have a tested, appropriate capacity and approved fire extinguisher at hand
in the boiler room.
There must be access or potential for access to outside air in the boiler room, such as a fixed opening
must be provided on top and bottom part of the adjacent wall, which is open to the and must be open always. For
proper combustion boiler needs continuous fresh air supply. (> 300 cm²)
Overheating of the boiler water protection is integrated in the control system.
It is recommended to use a dust mask when cleaning the boiler and emptying the ash drawer.
It is recommended that a lifting device should be used to move and transport the boiler.
The chimney or flue is one of the most critical factors in the successful operation of any solid fuel
heater, including your DEVRON boiler. A good chimney will provide a continuous and reliable draft to pull the
exhaust gases out of your boiler when the fan is not running. The boiler must be connected to an approved
chimney by local authorities. No other appliance should be connected to this chimney. The boiler should be
connected to the chimney with the shortest, (minimum 60cm and maximum 200cm with maximum 2x45 degree
elbows) and most direct run of black stove pipe. Maintain a minimum of 460 mm between the flue pipe and
combustible surfaces. Prior to operation, the installation should be inspected and approved by qualified
professionals (i.e., a chimney sweep, a licensed plumbing and heating contractor, electrician, etc.). Boiler will be
out of guarantee if it is not connected to a proper chimney, if you have problem with draft (too much or too little),
draft inducing fans or draft regulators may need to be considered. Condensation in the chimney must be
discharged before boiler.
Another important requirement is that the chimney and connecting pipe need to be insulated for safety
and to prevent condensation and a reduction in the draft caused when the gas in the chimney cools too much.
Do not use self-contained non-electric zone valves on the main heating zone as it is to be used as the
overheat/dump zone. Such a valve would prevent the overheat control from cooling the boiler when necessary.
Do not use any radiant floor heat tubing that does not have an oxygen barrier otherwise you must use a
heat exchanger between the boiler and the radiant floor heat tubing.
A backup power supply such as a UPS (battery-based Uninterruptible Power Supply) is required to
operate the primary circulation pump.
A primary circulation pump must feed all zones.
Each boiler should be connected to a heat accumulation tank (buffer tank) for proper operation, and the
capacity of the buffer tank must be according to local standards.
To protect the boiler against low-temperature corrosion the end-user should assure return temperature
does not reach lower than 55°C. Installing a three-way mixing valve or anti-condensation valve group (load valve

- 5 -
for buffer tank) can solve this. If there is no system installed for keeping the return temperature over 55°C, the
boiler will be out of warranty.
Before starting assembly, repairs or maintenance, as well as during any connection works, please make
sure that the main power supply is disconnected.
The boiler electric control regulator cannot be used if its casing is damaged.
In no circumstances can the design of the boiler, burner and electric control regulator be modified.
Keep the regulator out of reach of children.
Incorrect selection of the parameters can cause malfunction and serious problems of the boiler.(e.g.
overheating of the boiler, etc.).
The programmed parameters should only be altered by an authorized service.
The electric system in which the regulator operates must be protected by means of a fuse, selected
appropriately to the applied loads.
Directive WEEE 2002/96/EC: Act on electrical and electronic equipment.
•Recycle the product and the packaging at the end of the operational use period in an appropriate
manner.
•Do not dispose of the product together with normal waste,
•Do not burn the product.

8. INSTALLATION
All installation, assembly and maintenance work must be carried out exclusively by fully trained,
professionally qualified personnel and must conform with this manual and the local codes and requirements of the
authority having jurisdiction, or in the absence of such requirements, apply to the EEC directives and European
norms (EN).
This boiler must be installed in accordance with the rules in force and only in a well ventilated and frost
free spaces, indoor but other then living areas. Top and bottom ventilation openings must be according to local
codes.
Control of the heating system shall enable the specified designed indoor temperatures to be achieved
under the specified variation of internal loads and external climate and, protect building and equipment against frost
and moisture damage when normal comfort temperature level is not required.
It is essential that an appropriate pump is fitted in the circulation system which must be kept in automatic
operation (above condensation temperature) at all the times when the boiler in use. The energy created by the
boiler must be transferred out of boiler continuously up to end of combustion process.
The filling and make up water must be according to the specifications given in this manual. Long term
water treatment is essential to the economic operation and life of both new and refurbished heating systems.
All electrical connections must be according to current standards and wiring diagrams are given in this
manual. Please pay special attention to earth connections to all electrical items in the boiler room. Never use fuel or
water pipes as an earth connection.
After the installation of the boiler all the water and valves must be controlled for leakage.
A load valve (anti-condensation 3 way valve) or similar items should be installed for anti-condensation so
that the return temperature will be never below the limited temperature 55°C.
During wood gasifying, tar and condensates (acids) are created, and this process is much worse if the
return water the boiler temperature is less than 55°C.
Feed water temperature of the boiler must be adjusted to minimum 75-80°C.
The boiler must not be operated lower than 60 % output for a long time.
We recommend installing the boiler with hot water storage tanks (buffer tank) and load valve group which
guarantees economy in fuel and longer service life of the boiler as well as comfortable attendance.
During the mode with decreased output (summer mode and water heating) it is necessary to have a
buffer tank or can be switched to pellet burning mode in the start of the season.
Wood logs must be used only dried with min. 10% and max. 25 % moisture content (with a higher
moisture content up 45 % can burn without any guarantee and note that with high humidity boiler power and
efficiency is reduced and also tar problem occurs)
The choice of the right boiler size, that is its heating output, is a very important condition for economic
operation and right function of the boiler. The boiler must be chosen so that its nominal output responds to heat
loss of the heated volume.
8.1. SAFETY ARRANGEMENTS
Heating system safety arrangements shall be designed in accordance with the type of heating system,
energy source, and the way which the heat supply is provided to the heating system, i.e. automatically controlled or
manually operated. Minimum required safety arrangement other than the present systems on boiler is under the
responsibility of the installer and must be according to local codes and/or EN 12828. This is a manual running solid
fuel boiler so special attention must be applied for correct installation and safety.
8.2. FUELS
DEVRON boilers can be fired with high quality wood especially logs; 25-75 cm long, Moisture 20 %, Never
try to change fuel without qualified service approval.
Specified fuel is dried, hard, cut wood and logs of 60-120 mm diameter, with min. 20% and max. 25%
moisture content and calorific value of 15-17 MJ/kg.
Note: Logs of bigger dimensions is necessary to cut into halves or quarters (because of the requirement of
operation to nominal output). You can burn hard as well as soft wood. Wood must be dried!

- 11 -
DEVRON boilers can be fired with high quality wood pellets;
6 to 8 mm in diameter,
Moisture < 10 %,
Ash < 1 %,
Fines < 1%,
Lower calorific value > 17 MJ/kg.
Ashes must not melt and stick to each other.
You can use some other alternative solid fuels but never change fuel without qualified service
approval. Some parts can be changed according to fuel type.
Chimney
Attachment of the appliance to the flue must be always done with approval of authorized chimney sweeping
company. There must always be sufficient draft in the flue and flue gas must be draught to the atmosphere in all
possible operation conditions. For the right operation of the boiler the independent flue must be dimensioned in the
right way, the draught is influenced by the section of flue, height and roughness of the internal wall. In to the flue
where the boiler is attached, no other appliance can be attached. Flue draught must have the specified values. But
it must not be too high so as not to decrease the efficiency of boiler and interrupt burning. If the draught is too
strong, install a draft regulator to the bottom part of chimney (60 cm below the boiler flue tube connection point).
20x20 cm min. height 7m
Ø20 cm min. height 8m
15x15 cm min. height 11m
Ø16 cm min. height 12m
Exact dimensions of flue must be calculated according to local codes. Flue draught is specified in technical
parameters. Exhaust pipe must have the outlet into the chimney. If the boiler can not be attached to the chimney
directly, the exhaust pipe must be without heating surface and it must rise to the flue. Exhaust pipes must be tight
and resistant against flue gas leakage and clean able from inside. Exhaust pipes must not come through home and
utility spaces and the internal section of the exhaust pipe must not be narrowing to the flue. Using of 90° bents is
not suitable.
Connecting the boiler to the mains net
The boiler is connected to the mains of 230V, 50Hz by a supply cord and plug. The voltage is of M type and
when replaced, the same type must be used by a service organization. The appliance must be located in such a
way that the plug was within the reach of the attendance.
8.3. FLUE GAS EXHAUST SYSTEM.
DEVRON type boilers are B23 type appliance so the flue gases must be connected to an adequate draught
chimney, (-1 to -6 mmWC) without any flue gas leakage to the boiler room.

b Organic substances are generally a mixture of several different compounds. The composition of such
mixtures and the behavior of their individual components under the conditions of boiler operation are difficult to
predict. Organic substances may be decomposed to form carbonic acid or other acidic decomposition products
which increase the acid conductivity and cause corrosion or deposits. They also may lead to foaming and/or
priming which shall be kept as low as possible.
Note: During boiler economic life, the total make up water volume can not be more then 3 times of the total
system water.
Guarantee will not be valid, if the boiler is out of service because of corrosion, sludge formation and deposits.
In order to prevent corrosion special care needed for oxygen infusion to the heating system water side.
Possible points for oxygen infusion are from open vented cisterns, negative pressure points on the system and
some gas permeable system items like plastic pipes.

Feed screw will start to work continuously. After 6-7 minutes later, pellet feeding screw will
be filled with pellets. Wait to see for pellets coming out of flexible hose for an extra 2 minutes in
order to be sure that you fill the screw completely. After 2 minutes stop the screw.
Before first start up and every time pellet specifications is changed the fuel feeding quantity
must be calibrated. Whenever the heating pellets are changed (size or length of pellet, density, etc.)
the feeding rate of pellet screw will also change, which will affect combustion dramatically.
After filling the screw, empty the pot and then run the pellet feeding screw for 15 minutes.

- 18 -
Weight the pellets in pot. Note the weighted pellets in grams. (X = ….. gram)
The first calibration must be performed by the service. The service you will use will make the
necessary adjustments after the first calibration process according to the gypsum and boiler
capacity. But if you change the pellet you are using and you experience a decrease in performance,
you will have to perform a calibration again and change the parameters given below.
First, while the boiler is cold and not working, pull the grille with the help of the handle on the side.
Make sure the front ash box is in place and clean.
Press Set. Go to the "Upload" menu. Set the status to "on". The pellet feed will then enter the circuit
and feed the pellet continuously for 10 minutes. At the end of this process weigh the pellets that
accumulate in the anterior ash pellet (the pellets will fall down here because the grid is drawn).
Compare your result with the table below. Assign values P05 and T03 of the closest corresponding
value to the table as new values for gain.
Do this only after replacing the pellet you used after the first servicing, and if you notice a
