2 INSTALLATION
ITALIA
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.
WARNING: Before installing the boiler,
the installer MUST make sure that the
wall can support the weight.
2.1 BOILER ROOM
The boilers MURELLE HE 110 R ErP can
be installed in boiler rooms whose size and
requirements meet current regulations.
Furthermore, vents, with surface areas at
least 3.000 sq. cm or 5.000 sq. cm for gas
with density over 0.8, must be installed in
the outer walls for room ventilation.
2.2 INSTALLATION
2.2.1 Single boiler (fig. 4)
A single function compensator kit is availa-
ble upon request code 8101581.
The kit is for use on an accumulating boiler
with capacity equal to or greater than 80
litres. Depending on the type of exhaust
fumes chosen and described in section 2.6,
set the following parameter:
- PAR 9 = You see TABLE 1-2-3-3/a.
Refer to section 3.3 to access the
INSTALLER PARAMETERS section.
2.2.2 Sequence/cascade boilers
For sequence/cascade installations using
polypropylene smoke collectors with a cla-
pet valve, every single boiler that makes up
the heating system must have the following
installation parameters modified:
- PAR 1 = 69 (for G20 NATURAL GAS boi-
lers).
- PAR 1 = 71 (for G31 PROPANE boilers)
Refer to section 3.3 to access the
INSTALLER PARAMETERS section.
ATTENTION: In the event that intake
pressure drops are applied to sequence/
cascade installations, it is important to
verify the CO at MAX and MIN capacity
2
and, if necessary, bring it back to the
correct value described in section 4.2.2.
In sequence/cascade installations, it is
mandatory to arrange the thermal system
with the hydraulic separator and safety
devices.
2.3 CONNECTING UP SYSTEM
To protect the heat system from damaging
corrosion, incrustation or deposits, before
installation it is extremely important to

WARNING :
- It is mandatory to arrange the thermal system with the hydraulic separator.
- When replacing one or more boilers in existing plants, it is advisable to
install a heat exchanger to separate the boiler circuit from the secondary
circuits. See the pressure curve for the boiler supply shown in figure 14.
clean the system using suitable products
such as, for example, Sentinel X300 (new
system), X400 and X800 (old system) or
Fernox Cleaner F3. Complete instructions
are provided with the products but, for fur-
ther information, you may directly contact
SENTINEL PERFORMANCE
LTD or FERNOX COOKSON ELECTRONICS.
For long-term protection agains corrosion
and deposits, the use of inhibitors such as
Sentinel X100 or Fernox Protector F1 is
recommended after cleaning the system.
It is important to check the concentration
of the inhibitor after each system modifica-
tion and during maintenance following the
manufacturer's instructions (specific tests
are available at your dealer).
The safety valve drain must be connected to
a collection funnel to collect any discharge
during interventions. If the heating system
is on a higher floor than the boiler, install
the on/off taps supplied in kit optional on
the heating system delivery/return pipes.
WARNING: Failure to 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
density must be taken into account.
The sections of the piping making up the
system must be such as to guarantee
EXPORT

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);
SOLUTIONS – 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 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
3 /h and gas
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
