The boiler must be installed in a fixed location and only by specialized and qualified person in compliance with all instructions contained in this manual. The installation of this
boiler must be in accordance with the relevant requirements of the current Gas
Safety (installation and use), the local building regulations, and and I.E.E. wiring regulations. Detailled recommendations for air
supply are given in BS5440:2. The following
notes are for general guidance: it is not necessary to have a purpose provided air vent
in the room or compartment in which the
appliance is installed.
2.1 ANTI-FREEZE FUNCTION
The boilers are equipped with anti-freeze
function which activates the pump and the
burner when the temperature of the water
contained inside the appliance drops to
below 6°C. The anti-freeze function ca only
operate if:
- the boiler is correctly connected to the
gas and electricity supply circuits;
- 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 protected.
2.2 FIXING THE WALL
MOUNTING BRACKET
– Mark the position of the two wall mount-
ing bracket fixing holes and the flue/air
duct hole on the appropriate wall(s).
– Drill a top two fixing holes using a 10 mm
masonry drill and fit the plastic plugs
provided.
– Accurately measure the wall thickness,
and note this dimension for later use.
– Secure the wall mounting bracket in
position using the screws provided.
Ensure that it is the correct way up, as
indicated in fig. 4.
2.3 CONNECTING UP SYSTEM
Before connecting the boiler it is recommended that the system be flushed in
accordance to BS 7593, to eliminate any
foreign bodies that may be detrimental to
the operating efficiency of the appliance.
When connecting up the boiler the clearances
in fig 1 and 1/a should be respected. The boiler is supplied with a valve pack part number
518 48 17.
A safety valve set at 3 bar is fitted to the
appliance, the discharge pipe provided
should be extended to terminate safely away
from the appliance and where a discharge
would not cause damage to persons or property but would be detected. The pipe should
be a minimum of 15 mm Ø and should be
able to withstand boiling water, any should
avoid sharp corners or upward pipe runs
where water may be retained.
Gas Connection
The gas connection must be made using
seamless steel or copper pipe, galvanized and
with threaded joints provided with gaskets,
excluding three-piece connections, except for
initial and end connections. 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 m3/h and the relative density of
the gas in question.
The sections of the piping making up the system must be such as to guarantee 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 badge is sited 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 (fig. 5)
To ensure safe disposal of the condensate
produced by the flue gases, reference should
be made to BS6798:2000. The boiler incorporates a condensate trap which has a seal of
75mm, therefore no additional trap is
required. The condensate should ideally be discharged internally into an internal waste
pipe(washing machine/sink waste) or a soil
pipe to avoid the risk of freezing. External pipe
runs should be avoided, but if it is necessary,
the pipework should be at least 32mm and
protected from the risc of freezing with a
waterproof insulation and the length kept to a
minimum and not exceeding 3 m. termination
should be into an external gully or purpose
made soakaway.
NOTE: All pipework must have a continuous
fall from the boiler and must be resistant to
corrosion by condensate, copper
or steel is
NOT suitable. It should be noted that the
connection of a condensate pipe to a drain
may be subject to local building control
requirements.

2.3.2 Requirements for sealed water
systems MURELLE HE
The heating system design should be based
on the following information:
a) The available pump head is given in fig. 16.
b) The burner starts when the C.H. flow
reaches 400÷450 l/h. This safety condition is ensured by the flow switch.
c) The appliance is equipped with an internal
by-pass that operates with system heads
(H) greater than 3 m. The maximum flow
through the by-pass is about 300 l/h. If
thermostatic radiator valves are to be
installed, at least one radiator should be
without a thermostatic valve (usually the
bathroom radiator).
d) A sealed system must only be filled by a
competent person using one of the
approved methods shown in fig. 5/a. The
system design should incorporate the
connections appropriate to one of these
methods.
2.3.3 Requirements for sealed water
systems MURELLE SYSTEM HE
The heating system design should be based
on the following information:
a) The available pump head is given in fig. 16.
b) The appliance is equipped with an internal
by-pass that operates with system heads
(H) greater than 3 m. The maximum flow
through the by-pass is about 300 l/h. If
thermostatic radiator valves are to be
installed, at least one radiator should be
without a thermostatic valve (usually the
bathroom radiator).
2.4 CHARACTERISTICS OF FEEDWATER
– All recirculatory systems will be subject to
corrosion unless an appropriate water
treatment is applied. This means that the
efficiency of the system will deteriorate as
corrosion sludge accumulates within the
system, risking damage to pump and
valves, boiler noise and circulation problems.
– For optimum performance after installa-
tion this boiler and its associated central
heating system must be flushed in accor-
dance with the guidelines given in BS
7593 “Treatment of water in domestic
hot water central heating systems”.
– This must involve the use of a proprietary
cleanser, such as Sentinel X300 or X400,
or Fernox Superfloc. Full instructions are
supplied with the products, but for immediate information please contact GE Betz
(0151 420 9563) or Fernox (01799 550
811) directly.
– For long term protection against corro-
sion and scale, after flushing it is recommended that an inhibitor such as Sentinel
X100, or Fernox MB-1 or Copal is dosed
in accordance with the guidelines given in
BS 7593.
Failure to flush and add inhibitor to the
system may invalidate the appliance
warranty.
– It is important to check the inhibitor con-
centration after installation, system modification and at every service in accordance with the manufacturer’s instructions. (Test kits are available from inhibitor
stockists).
– At every service the Aquaguard Filter
(4.5.2) should be checked and cleaned.

2.6 INSTALLATION OF SEPARATE
DUCTS (ø 80)
The kit with dedicated pipes enables to
separate the exhaust fumes pipes from the
air suction pipes (Fig. 7):
- The kit with dedicated ø 80 pipes, code
8089912, includes a SUCTION DIAPHRAGM THAT IS NOT used for these
models. To be able to use the air tap, cut
its base with a tool (A) and assemble it
(B).
The maximum overall length, resulting
from the sum of all the suction and
discharge pipes, is determined by the
load losses of the single connected accessories and should not exceed 10 mm H2O
(version HE 12) - 13 mm H2O (version HE
20) - 15 mm H2O (version HE 25-30-35)
(ATTENTION: the total length of each pipe
should not exceed 50 m, even if the total
loss is belo
w the maximum applicable
loss.)

The diagrams of Figure 9 show a few examples
of the permitted exhausts configurations.
2.7 POSITIONING THE
OUTLET TERMINALS
The outlet terminals for forced-draught
appliances may be located in the external
perimeter walls of the building.
To provide some indications of possible solutions, Table 4 gives the minimum distances
to be observed, with reference to the type
of building shown in fig. 10.
2.8 ELECTRICAL CONNECTION
The boiler is supplied with an electric cable.
Should this require replacement, it must be
purchased exclusively from SIME.
The electric power supply to the boiler must
be 230V - 50Hz single-phase through a
fused main switch, with at least 3 mm spacing between contacts. Respect the L and N
polarities and the earth connection.
NOTE: SIME declines all responsibility for
– If the terminal discharges into a pathway or passageway check
that combustion products will not cause nuisance and that the
terminal will not obstruct the passageway.
– Where the lowest part of the terminal is fitted less than 2 m
(78 in) above ground, above a balcony or above a flat roof to
which people have access, the terminal MUST be protected by
a purpose designed guard. Terminal guards are available from
Quinnell, Barrett, and Quinnell, Old Kent Road, London. State
model C2, (G.C. Part No 382946).
– Where the terminal is fitted within 850 mm (34 in) of a plastic
or painted gutter, or 450 mm (18 in) of painted eaves, an aluminium shield at least 1,500 mm (59 in) long must be fitted to
the underside of the painted surface.
– The air inlet/outlet flue duct MUST NOT be closer than 25 mm
(1 in) to combustible material.
– In certain weather conditions the terminal may emit a plume of
steam. This is normal but positions where this would cause a
nuisance should be avoided.
Terminal position Minimum spacing
A Directly below an openable window, air vent
or any other ventilation opening 300 mm 12 in
B Below guttering, drain pipes or soil pipes 75 mm 3 in
C/D Below eaves, balconies or carpor t roof 200 mm 8 in
E From ver tical drain pipes or soil pipes 75 mm 3 in
F From internal or external corner s 300 mm 12 in
G Above adjacent ground, roof or balcony level 300 mm 12 in
