2 INSTALLATION INSTRUCTIONS
The boiler must be installed by personnel authorised by the relevant national authorities, in
compliance with the applicable laws and regulations.
This boiler is suitable for heating water to a temperature below boiling point at atmospheric
pressure. It must be connected to a heating installation and/or a domestic hot water distribution
network, which must always be compatible with its performance and power.
This appliance must only be used for the purpose for which it has been expressly designed. Any
other use is considered unsuitable and therefore hazardous. The manufacturer shall not be
considered liable under any circumstances for damage caused by unsuitable, erroneous or
irrational use.
Remove all the packaging and check the contents are complete. In case of doubt, do not use
the boiler. Contact your supplier. Keep the packaging elements out of reach of children, as they
can be dangerous.
When you no longer wish to use the boiler, disable the parts that could be a potential source of
hazard.
2.1 Location
The boiler must be installed in a sufficiently ventilated site, away from humidity. It must be
located so that the air grilles on the premises are not obstructed and normal boiler
maintenance is possible even if it is placed between items of furniture. One metre of free
space must be left above the boiler for this purpose.
2.2 Hydraulic installation
The hydraulic installation must be made by qualified personnel. The applicable installation
legislation is to be complied with, and the following recommendations should also be taken
into account:
- It is obligatory and essential to install the external circulation kit supplied by
EKOPOWER with the boiler, to prevent any water condensation in the heat exchanger.
To correctly install the boiler, carefully follow the instructions given in the section
“Installing the external circulation kit” . If this requirement is not complied with,
EKOPOWER’s guarantee of the appliance will automatically be null and void.
- The inside of the installation piping should be thoroughly cleaned before switching on the
boiler.
- We recommend inserting cut-off valves between the installation piping and the boiler to
simplify maintenance tasks.
- Leave a free space around the boiler for carrying out any maintenance and repair
operations.
- Drain valves and suitable devices for correctly bleeding the air from the circuit during the
boiler filling stage should be fitted.
- Install all the necessary safety elements (expansion vessel, safety valve, etc.) to comply
with the applicable regulations for the installation.
- If the boiler is installed at a lower height than the heating installation, it is recommendable
to create a siphon at the boiler outlet, to prevent the installation from heating up due to
natural convection when heating is not required.

2.3 Installing a Sanit hot water tank (Optional)
The procedure for suitably connecting a Sanit DHW tank to the Ekoheat boiler is as follows:
- Unplug the boiler from the mains.
- Connect a DHW temperature sensor (supplied optionally) to the sensor terminal strip J2
(Sa; terminals 10 and 11) (see ”Electrical Diagram" page 44).
- Insert the temperature sensor bulb in the bulb-holder sheath provided on the hot water
tank.
- Connect the 3-way DHW diverter valve to the supply terminal strip J1 (V3V; terminals 3
and 6) (see "Electrical Diagram" page 44).
The hydraulic installation for the 3-way DHW diverter valve should be made so that the
heating circuit can flow through the valve when it is in rest position (not energised):

For correct hydraulic installation of the hot water tank, carefully follow the assembly and
connection instructions enclosed with the same.
2.4 Fuel
The EkoHeat boiler must be fuelled by EN PLUS certified wood pellet. The EN PLUS certificate
assures that the fuel’s humidity levels and calorific value are ideal for optimum boiler
functioning. If this requirement is not complied with, EKOPOWER’s guarantee of the appliance
will automatically be null and void.
The following points should be taken into account for correct fuel storage:
- The stored pellets should be kept dry all year round.
- The applicable legislation in each country for correct fuel storage must be complied with.

6
2.5 Installing the reserve tank
EKOPOWER supplies a reserve tank for storing the pellets with the boiler. The tank is
reversible and can be mounted on either the left or right side of the boiler. It is also equipped
with adjustable feet for height regulation.
IMPORTANT: Ensure the height of the elliptical holes on the sides of the boiler and on
the reserve tank coincide, for correct insertion of the feed auger. To do
this, make the necessary adjustments for height (using the adjustment
feet) and depth (correctly positioning the reserve tank).

EKOHEAT
7
2.6 Electrical Connection
The EkoHeat boiler is equipped with a 230 V~ 50 Hz mains connection plug. The socket
should have an appropriate earth connection.
The terminal strip J1 includes terminals for connecting the feed auger, the external circulation
kit circulating pump, an ambient thermostat and the 3-way diverter valve for the optional
DHW circuit. The terminal strip J2 includes terminals for connecting a sensor for the optional
DHW circuit. This sensor must be supplied by EKOPOWER.
For correct connection of the burner, the burner connections should be made to terminal
strips J3 and J4 (see "Electrical Diagram" page 44).
IMPORTANT: Before carrying out any work on the boiler’s electrical installation,
always ensure it is disconnected from the mains.
2.7 Combustion product removal
The EkoHeat boiler is a biomass boiler and it is essential for it to be connected to a flue, i.e.
a smoke duct able to create a pressure drop (which in this case should be between 0.15 and
0.20 mbar), in compliance with the applicable laws to this regard.
The combustion product exhaustion ducts must be installed by qualified personnel and must
comply with the regulations in force. For the flue to create a pressure drop, the following
recommendations should be taken into account:
- It should be suitably insulated.
- It should be independently located, with a separate flue for each boiler.
- It should be vertical, avoiding any angles greater than 45º.
- It should always have the same diameter. It is recommendable for it to be circular, and
never any narrower than the boiler outlet.
- It is obligatory to install a fume inspection plate with condensation collection, to
remove the condensation generated in the flue. Otherwise, the condensation may
reach the inside of the boiler and cause irreparable damage, which would not be
covered by EKOPOWER’s guarantee. The condensation pipe should lead to a drain
outlet, as a large amount of water may be generated. This connection must be made in
compliance with the regulations for draining off condensation water to the drain network.
- It is recommended to install a draught stabiliser to prevent any pressure drop
variations in the flue due to atmospheric conditions, which could affect correct boiler
combustion. This draught stabiliser must be installed below the fume inspection
plate to prevent any leakage of combustion gases.
