The boiler must be installed by personnel authorised by the Department of Industry in accordance
with the applicable regulations and standards in force. However, the following recommendations
must also be complied with when installing the boiler:
3.1
3.13.1
3.1 Location

The boiler must be installed in a enough ventilated room and sufficient access space must be
maintained to carry out preventive or corrective maintenance operations.
3.2

Flue
This type of boiler must be connected to a flue. A flue is a fume outlet pipe able to generate a
depression, which in the case of the Jaka
Jaka Jaka
Jaka HF
HFHF
HF and Jaka HFD
Jaka HFDJaka HFD
Jaka HFD should be at least 1.5 mmca. In order
for the flue to create a depression the following recommendations should be taken into account:
- It should be suitably heat-insulated.
- It should be fitted separately, with one flue for each boiler.
- It should be vertical and have no angles of over 45º.
- It should protrude one metre from the roof ridge or from any adjacent building.
- It should always have the same diameter. Ideally it should be circular, and its diameter must
never be less than that of the boiler outlet.
However, flues must always be constructed in accordance with the installation regulations in force.

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:
- 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.

The "Domestic

Domestic" burner is equipped with a self-priming pump, which allows the aspiration of fuel
from a tank installed at a lower level than the burner, as long as the vacuum measured with the
vacuum gauge in the pump does not exceed 0,4 bat (30cmHg).
The suction of fuel must never reach the bottom of the tank, always leaving a minimum distance of
10 cm to the bottom, if possible, the suction kit with float is recommended.
In installations that allow it, the fuel returns must be made to a recirculation filter with air purge,
thus avoiding oxidations in the diesel pump.

The installation must be provided with a fill valve for this purpose, with which it can be filled until a
pressure of 1 - 1.5 bar appears on the manometer (5)

from the boiler. The rest of the installation must also be suitably drained using the air drain valves
fitted for this purpose. When the installation has been filled, close the fill valve.

Various sensors may be incorporated to this control unit, enabling it to regulate two independent
heating zones: a circuit with a mixing valve (e.g. underfloor heating), and a direct circuit (e.g.
radiators). The installation can thus be adjusted to suit the needs of a particular home by measuring
the outside temperature and the room temperature inside the house in each of the two heating
zones. The control unit can also adjust the hot water production of a storage heater connected to the
boiler, giving priority to the hot water production.

Fix the burner support to the boiler, then fix the burner to the support. This will allow the correct tilt
of the flame tube towards the combustion chamber. Fit the intake and return tubes, inserting the
oil filter in the intake tube.

The "Domestic"

"Domestic" burner is equipped with a self-extracting pump, enabling fuel intake from a tank
installed at a lower level than the burner, provided the pressure difference measured with the
vacuum gauge at the pump does not exceed 0.4 bar (30 cmHg).

Ensure there is fuel in the tank, that the oil valves are open and that there is an electric connection
to the burner. Turn on the master switch. Unscrew the air bleed screw (manometer point). Then,
when the valve opens, remove the photocell sensor and move it towards a light source until fuel
comes out. Disconnect the burner and screw the bleed screw back in.

16.4 Adjusting the combustion conditions
Adjusting the combustion conditionsAdjusting the combustion conditions
Adjusting the combustion conditions
Observe the flame. If there is insufficient combustion air, it will be dark in colour and will produce
smoke, obstructing the flue outlet.
On the contrary, if there is an excess of combustion air, the flame will be pale or bluish in colour.
This will reduce the performance of the boiler and it will fail to comply with anti-pollution
standards, and the excess air may also hinder the ignition process.
The flame should be orange in colour.
If the shape of the boiler makes it difficult or impossible to observe the flame, the combustion air
flow can be regulated by observing the smoke coming out of the flue. If the smoke is dark in colour,
more air will need to be provided to the burner, and if it is very white, the air in the burner will need
to be decreased until no smoke at all is observed.
If you have a device for determining the composition of the combustion gases, this will be the best
guide for flame adjustment. If not, simply follow the above indications.

The burner’s LMO control box has a reset button which
is the key element for resetting the burner control and
activating/deactivating the diagnosis functions.
The multi-colour LED on the reset button is the
indicator for visual diagnosis. The button and the LED
are located under the transparent cover of the reset
button. During normal functioning, the various
operating statuses are indicated in the form of colour
codes (see the colour code table below). During
ignition, the indication is as shown in the following
table:
