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 BOILER ROOM
The "PLANET DEWY" version boilers can
be installed in any domestic environment
without any location restrictions or combu-
rent air requirements.
2. 1 . 1 "BT100" tank unit
"BFT" model may be paired with a separate
"BT100" tank unit.
The tank units may be installed near the
boiler (beneath or beside it) or in another
room. An optional hydraulic connection kit
(code 8091110) is available to facilitate
installation underneath the boiler.
2.2 INSTALLATION PLATE
To mount the installation plate supplied as
an optional extra (kit code 8081205), follow
the instructions written below (fig. 4):
– Fix the connecting sheet to plate (A) and
lower plate (B).
– With the template complete, fix plate (A)
to the wall using the two boiler support
screws.
– Check that plate (B) is perfectly horizon-
tal using a spirit level.
– Connect the bends or connecting val-
ves supplied in the optional kit to the
system pipes.

2.2. 1 System connection unions
The following optional accessories are avail-
able to facilitate water and gas connection
of the boiler with the heating system:
– codos kit, code 8075418
– cock kit, code 8091806
– kit for replacement of other brands' wall-
mounted units, code 8093900.
Detailed instructions for assembly of the
unions are provided with the kits.
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.
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
connections, except for initial and end con-
nections.
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 /h and the relative density of the gas in
3
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).
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.
CAUTION: If water is supplied at a pressu-
re of more than 4 bar, an appropriate
R

pressure reducer must be installed to
prevent damage to the boiler. Sime shall
not be held liable for such damage.
2.3. 1 Connection of condensation
water trap
The drip board and its water trap must be
connected to a civil drain through a pipe
with a slope of at least 5 mm per metre to
ensure drainage of condensation water.
The plastic pipes normally used for civil
drains are the only type of pipe which is
appropriate for conveying condensation
to the building's sewer pipes.
2.3.2 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 equip-
ped, install an adequate filter on the gas pipe.
2.4 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
should be installed. To prevent lime scale or
deposits on the primary exchanger, the
water used to supply the heating circuit
should must be treated 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.
2.5 SYSTEM FILLING
The boiler and the heating system are filled
with water as follows:
