4 INSTALLATION INSTRUCTIONS
The Fusion Hybrid Oil module can only be installed in combination with a heat pump from the DUAL
CLIMA line, supplied by DOMUSA TEKNIK . Therefore, for its operation, these devices should be
connected to each other, both hydraulically and electrically. In this section, the necessary operations
for said connection are described in detail.
The module must be installed by personnel authorised by the Ministry of Industry, in compliance with
the applicable laws and regulations. In general, these laws and regulations a are the "Basic Gas
Installation Standards", the "Heating, Air Conditioning and Domestic Water Installation Regulation"
and all other local regulations.
This support module 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 should 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 unreasonable use.
Remove all the packaging and check that the contents are complete. In case of doubt, do not use the
module and refer to the supplier. Keep the packaging elements out of reach of children, as they can be
dangerous.
When it is decided not to use the module anymore, the parts likely to constitute potential sources of
danger should be properly decommissioned.
4.1 Location
The module should be located at a sufficiently ventilated site. The module must be located so that
the air grilles on the premises are not obstructed and that normal maintenance is possible even if it
is placed between items of furniture.
4.2 Combustion product removal
It is essential that this type of boiler be connected to a flue, it being understood as a smoke duct
that that is capable of creating a depression (in this case, 1.5 mmH2O): 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 protrude one meter from the roof ridge or an adjacent building.
- It should always have the same diameter. It is recommended that it be circular, and never
narrower than the boiler outlet.
Nevertheless, it should always be built in accordance with current installation regulations.
4.3 Hydraulic installation of the heating and DHW circuit.
The hydraulic installation should be carried out by qualified personnel, in compliance with the
current installation regulation (RITE) and considering the following recommendations:
- It is recommended to use a correctly sized piping based on the installation in order to reach the
minimum water flow rate of the hydraulic circuit. The inside of the installation piping should be
thoroughly cleaned before switching on the module.
- We recommend inserting cut-off valves between the installation piping and the apparatus to
simplify maintenance tasks.
- If the module is installed at a lower height than the heating installation, it is advisable to create
a siphon at the boiler outlet, to prevent the installation from heating up due to natural
convection when heating is not required.
