Sime Format 25, Installer'S Instructions

Page: 78 / 100

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 “25/60 OF” version boilers must be
installed in adequately ventilated domestic
rooms. It is essential that in rooms where
the boiler are installed at least as much air
can arrive as required by normal combu-
stion of the gas consumed by the various
appliances. Consequently, it is necessary to
make openings in the walls for the air inlet
into the rooms. These openings must meet
the following requirements:
– have a total free section of at least 6
cm 2 for every kW of heat input, with a
minimum of 100 cm 2 ;
– They must be located as close as possi-
ble to floor level, not prone to obstruc-
tion and protected by a grid which does
not reduce the effective section required
for the passage of air.
The “25/60 BF - 30/60 BF” version boi-
lers may instead be installed, without any
constraints regarding location or supply of
air for combustion, in any domestic rooms.
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 Fixing jig (optional)
The fixing jig code 8081209 is supplied with
an instruction sheet for the fixing.
2.2.2 Fitting the pipe elbows (optional)
To fit the connecting elbows supplied in kit
code 8075419, follow the instructions
reported in fig. 5.
2.2.3 Fitting isolating valves (optional)
To fit the isolating valves, supplied in kit code
8091807, follow the instructions mentioned
in fig. 6.
2.2.4 Replacement wall kit
for other makes (optional)
The kit code 8093900 is supplied comple-
te with mounting instructions.
2.3 CONNECTING UP SYSTEM
To protect the heat system from damaging
corrosion, incrustation or deposits, after
installation it is extremely impor tant to
clean the system using suitable products
such as, for example, Sentinel X300 (new
systems), X400 and X800 (old systems)
or Fernox Cleaner F3 . Complete instruc-
tions are provided with the products but,
for further information, you may directly
contact SENTINEL PERFORMANCE SOLU-
TIONS LTD or FERNOX COOKSON ELECTRO-
NICS. For long-term protection agains cor-
rosion and deposits, the use of inhibitors
such as Sentinel X100 or Fernox Protec-
tor F1 is recommended after cleaning the
system. It is important to check the con-
centr ation of t he inhibit or af t er each
system modification and during maintenan-
ce following the manufacturer’s instruc-
tions (specific tests are available at your
dealer). The safety valve drain must be con-
nected to a collection funnel to collect any
discharge during interventions.
WARNING: Failur e t o clean the heat
system or add an adequate inhibitor inva-
lidates the device’s warranty.
Gas connections must be made in accor-
dance with current standards and regula-
tions. When dimensioning gas pipes from
the meter to the module, both capacity
volume (consumption) in m 3 /h and gas
density must be taken into account.
The sections of the piping making up the
system must be such as to guarantee a
