INSTALLATION
The boiler must be installed in a fixed loca-
tion and only by specialized and qualified
firms in compliance with all instructions
contained in this manual.
Furthermore, the installation must be in
accordance with current standards and
regulations.
2. 1
VENTILATION
OF BOILER ROOM
The "PLANET AQUAQUICK" version boi-
lers can instead be installed in any dome-
stic environment without any location
restrictions or comburent air require-
ments.
2.3
ACCESSORIES AVAILABLE
UPON REQUEST FOR
CONNECTION WITH
HEATING SYSTEM
The following optional accessories are avail-
able to facilitate water and gas connection
of the boiler with the heating system:
– Installation plate, code 8075407
– Codos and gas cock, code 8075421
– Small curve and gas/incoming hot water
taps, code 8075418
– Cocks kit, code 8091806
– Replacement wall kit for t he ot her
makes, code 8093900.
Detailed instructions for assembly of the
unions are provided with the kits.
2.4
CONNECTING UP SYSTEM
Before proceeding to connect up the boi-
ler, you are recommended to make the air
circulating in the piping in order to elimi-
nate any foreign bodies that might be
detrimental to the operating efficiency of
the appliance.
The discharge pipe of the safety valve
must be connected to a collector funnel
for channelling away any discharge if the
safety valve goes into action.
If the heating system is on a higher floor
than the boiler, install the on/off taps sup-
plied in kit code 8091806 on the heating
system delivery/return pipes.
The gas connection must be made using
seamless steel pipe (Mannesmann type),
galvanized and with threaded joints provi-
ded with gaskets, excluding three-piece con-
nections, except for initial and end connec-
tions. Where the piping has to pass through
walls, a suitable insulating sleeve must be
provided.
When sizing gas piping, from the meter to
the boiler, take into account both the volume
flow rates (consumption) in m
3
relative density of the gas in question.
The sections of the piping making up the
system must be such as to guarantee a
supply of gas sufficient to cover the maxi-
mum demand, limiting pressure loss
between the gas meter and any apparatus
being used to not greater than:
– 1.0 mbar for family II gases (natural gas);
– 2.0 mbar for family III gases (butane or
propane).
An adhesive data plate is sticked inside the
front panel; it contains all the technical data
identifying the boiler and the type of gas for
which the boiler is arranged.
2.4. 1
Filter on the gas pipe
The gas valve is supplied ex factory with an
inlet filter, which, however, is not adequate to
entrap all the impurities in the gas or in gas
main pipes.
To prevent malfunctioning of the valve, or in
certain cases even to cut out the safety
device with which the valve is equipped,
install an adequate filter on the gas pipe.
2.5
CHARACTERISTICS
OF FEEDWATER
To prevent lime scale and damage to the
tap water exchanger, the water supplied
should have a hardness of no more than
20°F. In all cases the water used should be
tested and adequate treatment devices

/h and the
should be installed.
To prevent lime scale or deposits on the
primary exchanger, the water used to sup-
ply the heating circuit should must be trea-
ted in accordance with UNI-CTI 8065
standards.
It is absolutely essential that the water is to
be treated in the following cases:
– Very extensive system (with high con-
tents of feedwater).
– Frequent addition of makeup water into
the system.
– Should it be necessary to empty the
system either partially or totally.
2.6
SYSTEM FILLING
The boiler and the heating system are using
the fill cock on the pressure switch valve (2
fig. 4). The charge pressure, with the sys-
tem cold, must be 1 bar. Filling must be
done slowly so as to allow any air bubbles to
be bled off through the air valves. Should
the pressure have risen well above the limit
expected, discharge the over pressure by
opening the pressure-relief valve.
Once the filling has been completed, close
the filling tap.

The air inlet-smoke outlet assembly, code
8084805, is included in the standard sup-
ply of the appliance complete with mounting
instructions.
