Connecting Up System - Sime MURELLE HM Para El Instalador

- the boiler is constantly fed;
- the boiler ignition is not blocked;
- the essential components of the boiler
are all in working order.
In these conditions the boiler is protected
against frost down to an environmental
temperature of -5°C.
ATTENTION: In the case of installation in a
place where the temperature drops below
0°C, the connection pipes must be pro-
tected.

CONNECTING UP SYSTEM

To protect the heat system from damaging
corrosion, incrustation or deposits, before
installation it is extremely important to
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
further information, you may directly con-
tact SENTINEL PERFORMANCE SOLU-
TIONS LTD or FERNOX COOKSON ELECTRO-
NICS.
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 dischar-
ge during interventions. If the heating
system is on a higher floor than the boiler,
install the on/off taps supplied in kit optio-
nal 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 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
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.
2.3. 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 equipped,
install an adequate filter on the gas pipe.
2.4 INITIAL PHASE SYSTEM FILLING
(fig. 5)
Filling of the boiler and the system is done
by the system filling (11). The charge pres-
sure, with the system cold, must be
between 1 and 1.5 bar.
N.B. The "25 T - 35 T" versions the loa-
ding is done by loading tap externally
mounted by the installer.
2.4. 1 System draining (fig. 5)
To drain the system, turn off the boiler and
use the discharge valve (7).
2.5 INSTALLATION OF

The axial suction and discharge pipes are sup-
plied in a special kit (that can be purchased
separately) along with assembly instructions.
The diagrams of fig. 6 illustrate some
examples of different types of discharge
modalities allowed and the maximum
lengths that can be reached.
