1.6 TECHNICAL DATA PLATE (fig. 3/a)

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.
PLEASE NOTE: Before fitting the flue to
the boiler, the condensate trap should
be filled, see 2.4.1
2.1 VENTILATION REQUIREMENTS
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.
2.2 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 can 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.
2.3 FIXING THE WALL
MOUNTING BRACKET (fig. 4)
– Mark the position of the two wall
mounting 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.
2.4 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 should be respected.
The boiler is supplied with valve pack
5184817B- combi, 8091821- system T.
A safety valve set at 3 bar is fitted to the
appliance, the discharge pipe 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, and 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. 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 output available from the
boiler, 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.
2.4.1 Connection of condensation
water trap
To ensure safe disposal of the condensate
produced by the flue gases, reference
should be made to BS6798:2009.
The boiler incorporates a condensate trap
which has a seal of 75 mm, therefore no
additional trap is required. The condensate
trap can be filled prior to the installation of
the flue by carefully pouring 1 litre of
water into the exhaust connection.
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.
2.4.2 Dealing with condensate
See Appendix 1- industry guidance on
dealing with condensate.
the connection to the boiler condensate
trap should be made with 20mm waste
pipe using the connector provided.
2.4.3 Requirements for sealed water
systems MURELLE ELITE HE
The heating system design should be
based on the following information:
a) The available pump head is given in
fig. 14.
b) The burner starts when circulation is
detected by a small pressure
fluctuation measured by the pressure
transducer.
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. The
system design should incorporate the
connections appropriate to one of
these methods.
2.5 CHARACTERISTICS
OF FEEDWATER
NOTE: If the domestic water supply is
metered or should a water meter be
added at a later time, a small expansion
vessel should be included in the
METHOD OF FILLING A SEALED SYSTEM

domestic water pipework.
– 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.
– Before connecting the boiler the
associated central heating system
must be flushed in accordance with
the guidelines given in BS 7593
“Treatment of water in domestic hot
water central heating systems”.
– Sime Ltd recommend only the use of
FERNOX products for the flushing and
final treatment of the system water..
This is particularly important in hard
water areas.
Failure to flush and add inhibitor to
the system may invalidate the
appliance warranty.

2.6 INSTALLATION OF COAXIAL
DUCT ø 60/100 - ø 80/125 (fig. 6)
See 2.4.1 Filling the trap, before fitting the
flue. The coaxial suction and discharge
pipes are supplied 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 flue options
allowed and the maximum lengths that
can be reached. It is essential that a flue
gas analysis test point is made available
directly above the boiler.
2.7 INSTALLATION OF SEPARATE
DUCTS ø 80 (fig. 7)
See 2.4.1 Filling the trap, before fitting the
flue. The kit with dedicated pipes enables
to separate the exhaust fumes pipes from
the air intake pipes (fig. 7).
It is essential that a flue gas analysis test
point is made available directly above the
boiler.
– 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
inlet connection, cut its base with a tool
(A) and assemble it (B).
The maximum overall length, resulting
from the sum of all the intake and
discharge pipes, is determined by the
load losses of the single connected
accessories and should not exceed 15
mm H2O (version HE 30-35-35T)
(ATTENTION: the total length of each
pipe should not exceed 50 m, even if the
total loss is below the maximum
applicable loss.)
See Table 1 for information on the load
losses of single accessories.

– 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.
– Where the terminal is fitted within 850 mm (34 in) of a plas-
tic or painted gutter, or 450 mm (18 in) of painted eaves, an
aluminium shield at least 1,500 mm (59 in) long must be fit-
ted to the underside of the painted surface.
– The air inlet/outlet flue duct MUST NOT be closer than 10
mm (0.4 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.

(*) For condensing boilers this distance can be reduced to 25 mm without
effecting boiler performance, but it will be necessary to protect the sur-
faces from the effects of condensate
(**) This dimension to be used with ventilated soffits. With unvented soffits
this can be reduced to 75mm and further reduced to 25mm when a flue
shield is used to protect from the effects of heat and condensation.
2.9.1 External Controls
The heat demand can be by a "clean
contact" (conforming to EN607301), room
stat or programmer connected to the
"TA" connection (figs. 11 – 11/a), CN6
terminals 7 & 8 after removing the link. A
230v switched demand to terminal 14
CN7 and removal of the "TA" link on
terminals 7 & 8 on CN6.
MURELLE ELITE HE 35 T ErP version the
D.H.W. demand can be by either a
thermistor or thermostat depending on
configuration, see section 2.9.5 and 3.3.
A permanent power supply must be
maintained.
2.9.2 Remote control
SIME HOME
connection (optional)
The boiler is designed for connection to a
remote control unit, supplied on request
(SIME HOME code 8092280/81).
The remote control unit SIME HOME
allows for complete remote control of the
boiler.
The boiler display will show the following
message:
For installation and use of the remote
control, follow the instructions in the
package.
NOTE: Ensure PAR 10 set to 1 (PAR 10 =
1).
2.9.3 External sensor
connection
The boiler is designed for connection to
an external temperature sensor,
supplied on request (code 8094101) in
conjunction with remote control (code
8092226), which can automatically
regulate the temperature value of the
boiler output according to the external
temperature.
For installation, follow the instruction in
the package.
It is possible to make corrections to the
values by adjustment of PAR 11.
The flow temperature will be regulated
with respect to the external temperature,
for this reason external sensors should
only be used with system boilers used
only for heating( no DHW) and System T
boilers using all four pipe connections.
For guidance only, flues
should be installed in
accordance with BS5440

in vers. “35 T”
The “MURELLE ELITE HE 35 T ErP”
version is provided with a D.H.W. sensor
(SB) linked to the connector CN5.
When the boiler is coupled to an external
cylinder, the sensor (SB) must be fitted
into a sleeve in the cylinder and PAR 2 set
to 3.
If the cylinder temperature is to be
controlled by a thermostat then PAR 2 is
set to 4.
Operations must be carried out by
authorized and qualified technicians.
2.9.6 Use with different
electronic systems
Some examples are given below of boiler
systems combined with different electro-
nic systems. Where necessary, the para-
meters to be set in the boiler are given.
The electrical connections to the boiler
refer to the wording on the diagrams (figs.
11 -11/a). The zone valve control starts at
every demand for heating of the zone 1 (it
is from part of the TA1 or the CR).
