2 10 1 Preparation for the condensate drain

The exhaust of the condensation produced by the appli-
ance POWER MAX during its normal operation, must be car-
ried out with an accessory (siphoned condensate collector)
that needs to be installed below the thermal module itself
as specified in its assembly instructions. The condensate
coming out of the drainer must be collected for dripping
into a taped vessel connected to the sewer system, if nec-
essary by interposing a neutralizer (for more information
see paragraph "Neutralising the condensate"), according
to the following procedure:
- Fit a drip tray near the condensate discharge outlet,
adding a condensate neutraliser if necessary
- Connect the drip collection receptacle to the local
drain or sewer system using a siphon.
The drip tray can be created by fitting a cup or simply a
polypropylene bend, suitable for collecting the condensate
that comes out of the appliance and any liquid leaking from
the safety valve.
The maximum distance between the condensate drainage
of the appliance and the socket (or socket pipe) must not
be less than 10 mm.
The connection to the local drain or sewer system must be
executed using a siphon in order to prevent unpleasant
odours from being released back into the room from the
sewer.
We advise using plastic (PP) piping for building the con-
densate drainage.
a
Never use copper pipes under any circumstances,
as the condensate itself will cause them to rapidly
deteriorate.

b
Execute the condensate drain outlet so as to prevent
combustion gases leaking into the environment or the
drain or sewage system by sizing the siphon (height
H) as described in Paragraph "Discharge of combus-
tion products".
b
Always maintain a slope angle "s" of over 3° and en-
sure that the diameter of any condensate drain pipe
is greater than that of the connection fitted at the
drain outlet

b
Connect the condensate drain hose to a domestic
water drain in accordance with national and local
legislation and standards.
b
Fill the siphon with water before activating on the
thermal module in order not to release any combus-
tion products into the environment when the thermal
module is first switched on.
b
The condensate drain must be suitably siphoned. Fill
the siphon with drain in order to prevent the release
of combustion products when the appliance is first
switched on.
b
It is recommended that condensate from the thermal
module and from the flue should be channelled to the
same drain pipe.
b
The connection pipes used must be as short and as
straight as possible. Any curves or sharp bends can
lead to hoses becoming clogged and, therefore, can
prevent proper condensate discharge
b
Size the condensate drain outlet so as to ensure the
proper drainage of waste liquids without leaks
b
The condensate drain must be connected to the
drain and sewage network in such a ways so that the
condensate may not freeze under any circumstances

2 11 Neutralising the condensate

The UNI 11528 Standard provides for mandatory neutrali-
sation of condensate for systems with total power of over
200 kW. For systems with total power from 35 to 200 kW,
neutralisation may or may not be mandatory depending on
the number of flats (for residential applications) or the num-
ber of occupants (for non-residential applications) served
by the aforementioned system.

2 11 1 Water quality requirements

It is ABSOLUTELY NECESSARY to treat the water system in
order for the heat generator to work properly and to guar-
antee its service life, as well as that of all its components.
This not only applies to jobs carried out on existing installa-
tions but also on new installations.
Sludge, lime-scale and pollutants contained in the water
can cause permanent damage to the heat generator, also
within a short time and notwithstanding the quality stand-
ards of the materials used.
Contact the Technical Assistance Centre for any further in-
formation on type and use of additives.
The heat transfer fluid (water) for the central heating circuit
must conform to the quality parameters given in the follow-
ing table:
