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 cur-
rent standards and regulations.
2.1 BOILER ROOM AND VENTILATION
The “ PLANET ” series may be installed,
without problems of location or combusti-
ble air, in any domestic environment.
2.2 BOILER SUPPORT BRACKET
For the mounting of the support bracket of
the boiler, which is supplied, observe the fol-
lowing instructions (fig. 4):
– Fix the bracket to the wall with appro-
priate dowels.
– Check with a spirit level that it is perfec-
tly in horizontal plane.
2.2.1 Installation plate (optional)
The installation plate code 8081209 is sup-
plied with an instruction sheet for the fixing.
2.2.2 Fitting the pipe elbows (optional)
To fit the conneting elbows supplied in kit
code 8075419, follow the instructions in
fig. 5.
The D.H.W. cock and the relative
stub pipe are supplied with the boiler.
2.2.3 Fitting the isolating
valves (optional)
To fit the isolating valves supplied in kit code
8091807, follow the instructions in fig. 6.
The D.H.W. cock and the relative stub
pipe are supplied with the boiler.
2.3 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. When making the hydraulic
connections, make sure that the dimen-
sions indicated in fig. 1 are respected.
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.
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 /h and the relative density of the gas in
question. The sections of the piping making
up the system must be such as to guaran-
tee a supply of gas sufficient to cover the
maximum 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.
2.3.1 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.

OF FEEDWATER

tap water exchanger, the water supplied
