When installing POWER EVO-X 50 DEP - 50 models, it is ES-
SENTIAL to consider the clearance required for the use of the
combustion analysis tool. The drawing above shows a situation
where the distances between the boiler and wall unit/recess
were defined by taking into consideration an instrument with a
length of 300 mm. Longer instruments require more space.
Instructions for the condensate discharge
2.5
connection
This appliance is designed to prevent the leakage of gasseous com-
bustion products via the condensate discharge pipe, thanks to a spe-
cial drain-trap located inside it.
All the components of the condensate drainage system must be cor-
rectly serviced as per the manufacturer's indications, and must not be
modified in any way.
The condensate drain outlet system downstream from the appliance
must be made in accordance with the relevant legislation and regula-
tions in force; this is the responsibility of the installer. The system must
be sized and installed so as to ensure the correct evacuation of the
condensate produced by the appliance and/or collected by the flue
gas evacuation systems. All the system components must be made to
the highest standards, using materials able to withstand the long-term
mechanical, thermal and chemical stress created by the condensate.

measurements in mm
Note: if the condensate drain outlet system is exposed to the risk of
freezing temperatures, always ensure a suitable level of pipe insula-
tion and consider increasing the diameter of the pipe itself.
The pipe must slope sufficiently to prevent the condensate from stag-
nating and guarantee it is correctly drained off. There must be an ex-
aminable disconnection between the condensate drain outlet pipe of
the appliance and the condensate drain outlet system.
Condensate neutralisation
2.6
Standard UNI 11528 makes condensate neutralisation compulsory for
systems with a total output of over 200 kW. For systems with an output
between 35 and 200 kW, neutralisation may or may not be compulsory
depending on the number of flats (for residential applications) or the num-
ber of occupants (for non-residential applications) served by the system.
Installation on appliances that are old or that
2.7
need to be updated
When the thermal units are installed on old systems or those re-
quiring modernisation, check that:
ƒ The flue is suitable for the temperature of the flue gases, calcu-
lated and built according to the standard, as straight as possible,
airtight, insulated, and has no blockages or constrictions. Refer
to paragraph "2.13 Flue gas exhaust and combustion air suc-
tion" for further information
ƒ The electrical system is installed by qualified personnel and
complies with the specific standards
ƒ The fuel supply line (and tank, if installed) respect the specific
standards
ƒ The expansion vessel ensures the total absorption of the expan-
sion of the fluid in the system
ƒ The flow rate, discharge head and flow direction of the circula-
tion pumps are correct
ƒ The system has been washed to remove sludge and encrusta-
tions, and the seals have been checked
ƒ A treatment system is fitted when the values of the supply/make-
up water are different from those indicated in the "2.14 Filling the
heating system and eliminating air" paragraph.
a
The manufacturer is not liable for any damage resulting from
the incorrect construction of the flue gas exhaust system.
Handling and removing the packaging
b
Do not remove the cardboard packaging until the place of
installation has been reached.
b
Before transporting and removing the package, put on pro-
tective clothing (PPE) and make sure you have the right
equipment and tools for the size and weight of the appliance.
b
This operation must be carried out by several people, using
equipment suitable for the size and weight of the appliance.
Make sure the load does not become unbalanced during
handling.
To remove the packaging, proceed as follows:
ƒ Remove the box.
ƒ Remove the front protective element (1).
ƒ Remove the upper and lower protective elements (2).
ƒ Remove the side protective elements (3).
ƒ Pull off the protective bag.
