1.- INSTALLATION INSTRUCTIONS
The compliance with the normative and legislation in force related to the subject is
essential for the proper installation of the boiler.
1.1.- Location
The boiler is to be installed into a sufficiently ventilated place.
1.2.- Uptake
It is essential for this type of boiler to be connected to an uptake, being defined as that
flue being capable of generating a depression (in our case of 2 mm/wc.). It is advisable,
for the uptake to be capable of generating a depression, to follow the recommendations
described below:
- It is to be provided with a suitable thermal insulation.
- It is to be separately fitted, building an uptake for each boiler.
- It is to be vertically mounted and angles higher than 45º are to be avoided.
- It is to stick up a metre through the roof ridge beam or any adjacent building.
- It is always to have the same section, the circular one is recommended, and it will
never be less than the boiler outlet diameter.
Note: If the design of the uptake is not capable of generate the necessary depression, it
can be possible to have a reduction in the quantity of combustion air, reducing the
heating output kW produced by the boiler.
1.3.- Hydraulic installation
The hydraulic installation is to be carried out by skilled personnel complying with the
installation standards and taking the following recommendations into account:
- The boiler has to be installed in an open hydraulic circuit.
- It is necessary to mount an air vent in the boiler, to avoid generation of air bubbles
inside the boiler.
- It is recommended to mount a drainage valve in the boiler.
- A thorough interior cleaning of the installation piping is to be performed prior to the
switching on of the boiler.
- It is recommended that cut-off valves be interspersed between the installation piping
and the boiler, in order to simplify the maintenance tasks.
1.4.- Electric installation
The boiler is ready to be connected at 220 V 50 Hz on plugs 1 and 2 of the terminal
strip. Do not forget to do grounding.

- 3 -
In addition, the boiler is provided with two terminals for the room thermostat connection
(see Electrical Diagram). For that, the bridge joining both terminals 3-4 is to be removed
and the room thermostat is to be connected there.
1.5.- Burner mounting
The model Sirena is supplied with an oil burner Domestic. Follow the next instructions
to mount the burner over the boiler:
- Dismount the cover of the oil combustion chamber.
- Cut the insolation, which covers the hole of the combustion chamber, with a cutter.
- Follow the installation guide included with the burner to install the oil circuit.
- The boiler is provided with two terminals 5 - 6 for the burner electrical connection.
1.6.- Draught regulator mounting
To mount the draught regulator supplied with the boiler, follow carefully the next steps:
- Keeping the boiler empty of water, screw the draught regulator in the hole provided
in the boiler for such a purpose, ensuring a good sealed of it.
- Introduce the hexagonal lever through the lateral hole displacing the plastic tube
and placing the lever over the horizontal plane.
- Slide the lever in such a position that allows to open and close the boiler charge
door.
- Fix the lever with the screw.
- Ignite the boiler and wait for the temperature reaches the desired one in the
thermometer.
- Then turn the draught regulator up to the temperature shown in the thermometer.
- With the principal air inlet-door closed fix the chain with it and leave it tight.
2.- INSTALLATION WATER-FILLING
Water filling is to be carried out slowly and with the air vent open, so that the installation air
will be released. In addition, the other parts of the installation are to be properly purged by
means of the air vent valves fitted for such a purpose. Once the installation has been filled
up, close the filling valve.
NOTE: Switching on the boiler without water could result in serious damage to it.
3.- SAFETY LOCKING
The boiler is provided with two types of operating safety locking:
3.1.- Temperature safety locking
It will occur every time the temperature in the boiler exceeds 110º C. The safety
thermostat built-in button will be pressed in order to unlock it, once the plug covering
this button has been previously loosened.

- 4 -
3.2.- Burner locking
It is caused by any failure which could exist in the burner or oil line. To unlock, press the
burner lighted push button which becomes put on .
NOTE: If any of these lockings were repetitive, contact the nearest authorised
Technical Assistance.
4.- BOILER OPERATING
There are two different operating situations:
4.1.- Operating with firewood
Set the draught regulator to desired temperature (red range). It is recommended to set
the temperature between 60 and 90 ºC.
Ignite the fire inside the combustion chamber using papers or similar to help its start.
Use always very dry firewood.
Note: Ensures that the heating circulating pump works correctly.
4.2.- Operating with oil burner
Set the control thermostat and the room thermostat (if any) to the desired temperature.
Set the main selector to "ON" position in order to switch on the boiler.
The burner will be put on. The burner will stop when the boiler has reached the
temperature selected in the control thermostat.
5.- BOILER STOP
Set the main selector to "ON" position in order to switch on the boiler.
6.- EQUIPMENT DELIVERY
The Technical Assistance Service, once the first start-up has been carried out, will explain
the boiler operation to the users by informing them about the most necessary remarks.
The fitter will be responsible for explaining to the users the operation of any control or
regulation device that is a part of the installation and it is not supplied with the boiler.
7.- BOILER MAINTENANCE
In order to maintain the boiler under correct operating conditions, a checking operation is
to be made by DOMUSA TEKNIK’s authorised personnel on a yearly basis. Once a year,
we recommend to clean carefully the boiler combustion chamber and flue gases pipes. It is
very important to ensure always that the boiler is full of water and that the circulating pump
works correctly.

10.- FAILURES
This section provides an index of the most common failures in both the burner and boiler.
10.1.- Burner failures
It has already explained that the burner is equipped with a locking system indicated by a
light, and it could unintentionally occur that it becomes locked making the push button
be put on. In this case, unlock it by pressing the push button.
FAILURE CAUSE REMEDY
- Oil valve closed Open
- Power supply is not reaching the boiler Check
IT DOES NOT
PUT ON - Nozzle faulty or dirty Replace or clean
- Poorly-adjusted electrodes Adjust
- Timer at automatic position Set it to manual
- Poorly-set room or boiler thermostat Set properly
- Nozzle faulty Replace
FREQUENT - Flame sensor dirty Clean

- Oil filter or burner pump dirty Clean
10.2.- Boiler failures
FAILURE CAUSE REMEDY
RADIATOR - The pump does not rotate Unlock the pump

plug is always to be
loose)
- Poorly-adjusted burner Adjust properly
EXCESSIVE - There is no sealing on the uptake Eliminate the leakage
NOISE - Unstable flame Check the burner
- Uptake with no thermal insulation Insulate properly
