Installation
The connection to the sewerage of the
condensate drain must be designed to avoid
the freezing of condensate.
Always provide for a discharge of conden-
sate in exhaust pipe not more distant than 1
meter from the boiler
4.1.6 Hydraulic system
OPERATING PRESSURE
Maximum operating pressure of the device is 6
bar (600 kPa); minimum one is 0.5 bar (50
kPa).
It is necessary to use protective elements
on replenishment/supply and hydraulic circuit
that protect the system from pressure higher
than 550 kPa. Protective elements have to
comply with EN 60335-2-102.
Do not expose the exchanger to cyclical
pressure changes as the fatigue stress is very
detrimental to the integrity of the system com-
ponents. In case that the hydraulic system gen-
erates suddenly pressure changing , it's manda-
tory to use protective elements to make the
boiler work with a constant pressure.
Pressure check of the heating circuit
has to be done with cold unit and water.
WATER FILLING
Feed the system up to operating pressure by
connecting a point of the hydraulic circuit to
water supply line.
The connection to water mains must be
done by using a filling device in accordance to
EN61770 that in particular avoids any the re-
flux of liquid from the plant in water supply.
DRAINING OF THE SYSTEM
Emptying of the system is made by acting on
the discharge valves of each unit and in some
points of the hydraulic system specific for this
purpose.
For more information on the characteristics of
hydraulic system see Chapter 5 in which differ-
ent types of plant are shown
4.1.7 Exhaust Flue
The chimney should be as straight as possible,
sealed and isolated. Should not have occlusions
or narrowing.
The overall potential of thermal groups
Corolla 1000 Series is more than 35 kW, so
they can be installed only in rooms that have
venting opening to the outside according to ac-
tual law (italian D.M. 12.04.1996).
The Corolla 1000 series generators
must be connected to a exhaust pipe system in
flame retardant polypropylene (PP) or suitable
materials according to UNI EN 677 and associ-
ated standards.
Never use a pipe if not expressly intended
for the specific purpose, because the action of
condensate will cause a rapid deterioration
.
If you decide to bring together in one manifold
the discharges of each unit, the diameter of the
pipe to be used for one or two packs Corolla
1000 series connected in series is Ø200 mm
(Figure 7). For cascade installations where
there are more than two machines the diame-
ter of the exhaust manifold must be properly
sizing, or simply connect up to two Corolla
packs using multiple lines Ø200 separated.
In any case when using manifold for ex-
haust evacuation is necessary to use the clapet
before of the manifold (one for each unit pre-
sent) to prevent that the combustion products
of the working units may go to the boiler room
by seeping in the units that are not working in
that time.
