INSTALLATION INSTRUCTIONS
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 be complied with when installing the boiler:
3.1
Location
The boiler must be installed in a sufficiently ventilated site.
The boiler must be accessible from the
side for maintenance purposes.
3.2
Hydraulic installation of the heating and DHW circuit.
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.
- 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.
- For correct boiler functioning, there must be a pressure of at least 0.5 bar in the domestic hot
water circuit.
- When the DHW supply pressure is over 5 bars, a pressure reducer must be fitted.
- It is recommended to install a thermostatic mixing valve at the DHW outlet to protect against
burns and to guarantee a constant, stable supply of hot water.
- Before starting up the unit, it is essential to install the condensation siphon supplied with the
boiler documentation on the condensation drain tube
on the back of the boiler.
-
The condensation pipe should lead to a drain outlet,
as the Evolution boiler is a condensation boiler and a
large amount of water may be generated.
This
connection should be made in accordance with the
regulations for draining off condensation water to the
drain network.
- Fill the siphon with water before starting up the unit, to
prevent fumes coming out of it.
3.3
Fuel installation
The
Evolution Solar HFD
boiler is supplied with a
Domestic
sealed oil burner (see model in
“Technical Characteristics”). To correctly make the fuel installation, proceed in accordance with the
burner instructions enclosed with this manual (see “Burner” section).
The oil line installation and start-up of the burner must be carried out by qualified, authorised
personnel.
