Kepo pellet boilers
Introduction
This manual is an integral part of the product. It is delivered together with the appliance even when the boiler is
handed over to another user. In the event of damage or destruction, a new manual will be provided at your request by
our customer service or a technician authorized by Kepo.
This boiler should be used only for the purpose for which it is intended by the manufacturer. The manufacturer has no
contractual or non-contractual liability for damages to people or the environment resulting from poor installation,
inappropriate handling or failure to follow the instructions listed in this manual.
Installing the boiler on the central heating system
Installation of the boiler and its accessories has to be carried out in line with all the regulations provided in this manual
as well as the notes made by the manufacturer.
Installation should be done by authorized personnel that bear all responsibility for it, in accordance with the manual.
In case the boiler is not installed in compliance with all provided conditions, authorized technician cannot commission
the boiler.
Proper boiler installation is essential for convenient boiler exploitation. Poor installation may result in poor boiler
operation, emergency servicing, inability to perform regular servicing and high servicing costs.
To avoid this and enjoy the comfort of your heating to the fullest, please install the boiler in compliance with the
instructions given in this manual.

Safety
•All boiler modifications are forbidden unless prior approval has been given by the manufacturer.
•At the first commissioning, the boiler should be handled by a person who is familiar with this manual and has
been trained by our technician. In case additional training is necessary, please contact our customer service.
•Make sure that there are no blockages or reductions in the dimension of air vents in the room where the boiler
is installed (recommended air vents are essential for proper combustion).
•Flue pipes that exhaust gasses must be cleaned regularly for proper boiler operation.
•Before commissioning, make sure that the door and ash pan are properly closed. Also, make sure that there are
enough pellets in the pellet tank.
•Combustion chamber door must not be opened during operation.
•Ash pan must be properly closed with two tightening nuts after emptying.
•Avoid direct contact with boiler parts that overheat during operation.
•After longer periods of boiler inactivity, it is necessary to check for any cloggings that may have occurred.
•If the boiler is disconnected from the central heating system, it is necessary to fill it up with water. If there is no
water in the boiler, a corrosion process may occur that can reduce its service life significantly.
•The temperature in the boiler room must not drop below 5°C as this may cause damage to the boiler and
activate safety devices that shut it down. If this happens, please contact our customer service. Please, do not
try to start the boiler or disable the safety devices on your own.
•In case the boiler stops operating with no proper notice on the display, please contact our customer service.
•Do not touch the boiler with wet parts of your body.
•The boiler and all its parts must be kept away from children and persons with disabilities without proper
supervision.
•Do not pull, split or bend electric cables that may by chance protrude from the boiler, even when the boiler is
unplugged.
•Place the power cord in such a way that it does not touch hot parts of the boiler, flue pipes or installations.
•The boiler must not be used to burn waste.
•Flammable liquids must not be used to fire the boiler.
•Do not insert anything other than pellets into the pellet tank. Using other fuels may damage the equipment
inside the boiler. The boiler is not designed to burn anything else but pellets!

Necessary installation and commissioning requirements
Before deciding to purchase our product, please study this manual carefully. Review your own situation and determine
whether you meet the installation requirements.
In later exploitation, any departures may cause the following:
•High costs of emergency servicing
•Significantly shorter service life of the boiler
•Poor pellet combustion
•Increased pellet consumption
In case you have any further questions or you need small corrections in the dimensions of the boiler room, ventilation
or flue gas exhaustion, please contact a Kepo technician or our customer service: + 381 31 783 927. If you meet these
requirements, you provide yourself with an economical, safe and long-term use of our product.
1. Minimum clearance of the boiler sides to the walls
•Left side: 65cm
•Right side: 50cm
•Back side: 0cm
•Front side: 100cm
•Room height: 60cm clearance from the top of the boiler
This enables our technician to perform annual service or fix possible boiler malfunctions quickly. It also enables you to
maintain the boiler and flue pipes smoothly.
If the minimum clearance is not provided, we will not be able to conduct any operations.
2. For proper operation, the boiler must be installed in a ventilated room
A fresh air vent must be made in the lower part of the room, 30cm above the floor, near the boiler, with a minimum size
of 100cm².
A vent for dirty air (pellet and ash dust) must be made in
the upper part of the room, 20-30cm below the ceiling,
with a minimum size of 150cm².
Due to possible boiler congestion caused by irregular
boiler and chimney maintenance, a certain amount of
smoke may penetrate the room. This makes the vent for
dirty air indispensable.
Kepo produces ø120mm pipes with decorative collars and
meshed endings that can be installed as the air vent.
These vents have to be made properly in order to prevent
any possible blockages.

3. To exhaust flue gasses, use only ø80, ø100 or ø120 flue pipes with silicone rubber bands
The maximum amount of flue pipes to connect the boiler to the chimney is as follows:
•Tee - 1 piece
•1000mm or 500mm straight pipes – 3m maximum
•Elbow 90° - 1 to 2 pieces
In case two 90° elbows are used, the maximum straight flue pipe length is 2m.
Horizontally mounted flue pipes must not exceed 1m, with a mandatory 3-5% drop at the boiler.
At the end of flue pipes installation, there must be an insulated chimney.
The minimum chimney diameter is ø130.
4. Insulated chimney connected to the boiler must be cleaned prior to commissioning
The manufacturer is not liable for any malfunctions caused by the lack of chimney maintenance.
The minimum frequency for cleaning the chimney is once a year. With larger diameter chimneys, the frequency is
extended accordingly.
Small-sized, square-shaped chimneys interfere with regular boiler operation. A chimney connected to the boiler cannot
be connected to any other device (e.g. another boiler, a furnace, a heater or other heating devices).
The minimum height of the external insulated chimney is 3m from the connection point of the flue pipes.
5. Supply voltage should be stable at 230V ± 5% max
In case this requirement is not met and a periodic voltage drop or jump occurs, the manufacturer is not liable for any
boiler malfunctions.
6. Proper boiler positioning
Once the boiler is installed, the leveling feet must be adjusted.
The minimum clearance of the boiler to non-combustible and poorly
combustible materials must be 50cm, whereas its minimum clearance to
combustibles must be 100cm!
In case the flue pipes must pass through combustibles, such as wooden walls,
they must be properly insulated.
If the boiler is installed on a combustible floor, it is vital to make a
non-flammable hearth pad with dimensions larger than those of the boiler
(at least 20cm longer than the back and sides and at least 0cm longer than
the front of the boiler).
If any of the above conditions is not met, the boiler cannot be commissioned!
