IMPORTANT
When carrying out commissioning of the boiler, you are highly recommended to perform the following checks:
– Make sure that there are no liquids or inflammable materials in the immediate vicinity of the boiler.
– Make sure that the electrical connections have been made correctly and that the earth wire is connected to a
good earthing system.
– Open the gas tap and check the soundness of the connections, including that of the burner.
– Make sure that the boiler is set for operation for the type of gas supplied.
– Check that the flue pipe for the outlet of the products of the combustion is unobstructed.
– Make sure that any shutoff valves are open.
– Make sure that the system is charged with water and is thoroughly vented.
–
Purge the system, bleeding off the air present in the gas pipe by operating the pressure relief valve on the
gas valve inlet.

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 BOILER ROOM
The “RMG Mk.II” boilers with a rating of
more than 35 kW must be equipped with a
technical room whose dimensions and
requirements correspond to the current
safety standards.
The minimum height of the boiler room
must comply with what is indicated in fig. 3
in relation to the overall thermal capacity.
The minimum distance between the walls of
the room and the external points of the boi-
ler (right, left side, rear) must not be less
than 0.60 m.
It is possible to place a number of appara-
tus next to each other, on condition that all
the safety and control devices can be
easily reached. In addition, to circulate air
in the room, air vents must be made on
the outside walls for which the surface
area must never be less than 3,000 cm2
and 5,000 cm2for gas with a density
greater than 0.8.
2.1.1 Handling
Once the boiler is in its place of installation
and the packaging has been removed, pro-
ceed as follows if it must be moved (fig. 3/a):
– remove the casing cover;
– attach the lifting brackets (located on the
rear of the boiler) and fasten it in place

with the screws provided;
– insert two 3/4” pipes in the holes in the
brackets, lift the boiler carefully and place
into position.
2.2 CONNECTING
UP SYSTEM
Before proceeding to connect up the boi-
ler, you are recommended to make the
water circulating in the piping in order to
eliminate any foreign bodies that might be
detrimental to the operating efficiency of
the appliance.
The unit must be connected up with rigid
pipe fittings which will not subject it to
stress of any kind.
The connections should be easy to discon-
nect using pipe unions with orientable con-
nections. You are recommended to install
suitable shutoff valves on the system flow
and return pipes.
In order to achieve a good water distribu-
tion inside the cast-iron body, the system
flow and return pipes should be connec-
ted to the same side of the boiler.
The boiler comes supplied standard with
the attachments on the right-hand side,
with the possibility of them being tran-
sferred to the left-hand side.
In that case, move the water distributor,
located on the return header, and the
thermostat bulbs located in the sheathe,
to the same side.
The thermal jump between the system flow
and return pipes should not exceed 20°C.
For this purpose, it is advisable to install a
mixer valve with corresponding anti-conden-
sation pump.
CAUTION: The system circulation pump or
pumps must go into action at the time of
boiler ignition.
For this purpose, you are recommended
to use an automatic system of prece-
dence.
The gas connection must be made using
seamless steel pipe (Mannesmann type),
galvanized and with threaded joints provi-
ded with gaskets, excluding three-piece con-
nections, except for initial and end connec-
tions. 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);
– 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 CHARACTERISTICS
OF FEEDWATER
It is absolutely essential that the water used
for the central heating system should be
treated in the following cases:
– Very extensive systems (with high con-
tents of feedwater).
– Frequent addition of makeup water into
the system.
– Should it be necessary to empty the
system either partially or totally.
2.3.1 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 SYSTEM FILLING
Filling must be done slowly so as to allow
any air bubbles to be bled off through the air
vents provided on the heating system.
The pressure of cold charging of the
system, and the pressure of pre-pressuri-
zation of the expansion vessel, must corre-
spond, or in any case must not be less than,
the height of the static column of the
system (e.g., for a static column of 5 m, the
pre-pressurization pressure of the expan-
sion vessel and the charging pressure must
correspond to at least 0.5 bar).
2.5 CONNECTING
UP FLUE
The flue for the atmospherical expulsion of
the combustion products from natural
draught appliances must meet the following
requirements:
– Be gas-tight to the combustion products,
waterproof and thermally insulated.
– Be built of materials suitable for keep
resisting to normal mechanical stresses,
heat, and the action of combustion pro-
ducts and their possible condensates.
– Follow a vertical path and not present
any throttling throughout its entire
length.
– Be adequately insulated to prevent phe-
nomena of condensation or smokes coo-
ling, in particular if located outside the
building or in unheated ambiences.
– Be set at an adequate distance from
combustible or easily inflammable mate-
rial by means of an air gap or suitable
insulating material.
– Have beneath the mouth of the first
smoke duct a chamber for collecting
solid material and any condensate; the
height of the chamber must be at least
500 mm.
Access to the chamber must be guaran-
teed by means of an opening provided
with an air-tight metal door.
– Have a circular, square, or rectangular
internal cross section; in the case of
square or rectangular sections, the cor-
ners must be rounded off with a radius
of not less than 20 mm. However,
hydraulically equivalent cross sections
are allowed.
– Be equipped with a chimney-pot at the
top, which must be outside the so-called
back-flow zone, so as to prevent the for-
mation of back-flow, which prevents free
discharge of the products of combustion
into the atmosphere.
Therefore, conform to the minimum hei-
ghts indicated in fig. 4.
– Be devoid of mechanical means of suc-
50

tion located at the top of the pipe.
– No overpressure should be present in a
chimney that passes within or close up
to inhabited rooms.
2.5.1 Sizing of flue
The correct sizing of the flue is an essential
condition for efficient boiler operation.
The main factors to be taken into conside-
ration for calculating the section are the
heat input of the boiler, the type of fuel, the
percentage of CO2, the mass flow of smoke
at nominal load, the temperature of the
smoke, the roughness of the internal wall,
and the effect of gravity on the draught
pressure, which must take into account the
external temperature and the altitude.
2.6 ELECTRICAL
CONNECTION
The boiler is supplied with an electric cable.
Should this require replacement, it must be
purchased exclusively from SIME. The elec-
tric power supply to the boiler must be
230V-50Hz single-phase through a fused
main switch, with at least 3 mm spacing
between contacts.
The room stat must be class II as specified
by standard EN 60730.1 (clean contact).
NOTE: Device must be connected to an
efficient earthing system.
SIME declines all responsibility for injury
or damage to persons, animals or things,
resulting from the failure to provide for
proper earthing of the appliance.
Always turn off the power supply before
doing any work on the electrical panel.
2.6.1 Control system
connection (optional)
In the electrical circuit a series of connec-
tors are provided for the installation of an
optional control system, marked by differ-
ent colours black, red and brown (fig. 5).
The connectors are polarised in such a way
that the order cannot be inverted. To install
the control system these connectors must
be connected and jumpers 4-5 and 11-12
must be removed from the terminal board
(marked in bold in fig. 6).
The control sustem allows for the use of
sensors and environment units whose con-
nectors, polarised and coloured, are found
in a bag inside the control board.

3.1 CONTROL BOX
The “RMG Mk.II” boilers are provided with
automatic ignition (without pilot burner).
They are therefore equipped with FM 11
and DTM 12 electronic control and protec-
tion, with a built-in transformer, located insi-
de the instrument panel protection box.
Ignition and flame detection is controlled by
two electrodes located on the burner.
These guarantee maximum safety with
intervention times, for accidental switching
off or gas failure, within 8 and 4 seconds
(fig. 8).

3.1.1 Operating cycle
Before igniting the boiler, use a voltmeter to
make sure that the electrical connection to
the terminal block has been made properly,
respecting the position of live and neutral,
as shown in the diagram. Then press the
switch on the control panel detecting volta-
ge and lighting the led lamp.
The boiler is now ready to start working; a
discharge current is sent to the ignition
electrode through the programmer, and the
gas valve opens at the same time.
Burner ignition normally takes place within
2 or 3 seconds. However, it is possible for
ignition failures to occur, with consequent
activation of signal indicating that the equip-
ment has “locked out”.
Failures may be due to one of the following
causes:
–Gas failure
The control box runs through the cycle
normally sending electric power to the
ignition electrode. The electrode conti-
nues spark discharge for a maximum of
8 and 4 sec. If the burner does not igni-
te, the control box “locks out”.
This may occur upon first ignition or
after long periods of boiler lay-off when
there is air in the pipes. It may be caused
by the failure of the gas valve to open
owing to a break in the electric coil.
.
–Ignition electrode fails to spark
In the boiler, only opening of gas to the
burner is seen to occur. After 8 and 4
sec. the control cox “locks out”.
This may be due to there being a break
in the wire of the electrode or the wire
not being properly fastened to the termi-
nal of the control box; or else, the tran-
sformer has burnt out.
–No detection of flame
The continuous spark discharge of the
electrode is noted starting from ignition
even though the burner is lit.
After 8 and 4 seconds have elapsed, the
sparks cease, the burner goes out, and
the warning lamp indicating equipment
“lock-out” lights up.
This occurs when the position of live and
neutral has not been respected on the
terminal block. There is a break in the
wire of the sensing electrode or the elec-
trode itself is earthed: the electrode is
worn out and needs replacing.
The control box is falty
When there is a sudden voltage failure, the
burner shuts out immediately; when power
supply returns, the boiler will start up again
automatically.
3.1.2 Ionization circuit
The ionization circuit is to be checked using
a dial-type micro-ammeter, or preferably a
digital micro-ammeter with a 0 to 50 µA
scale. The micro-ammeter terminals must
be series-connected to the wire of the sen-
sing electrode. Under normal operating con-
ditions, the value oscillates between 6 - 10
µA. The minimum value of the ionization cur-
rent for which the equipment can “lock out”
is about 1 µA.
In this case, make sure that there is a good
electrical contact and check the degree of
wear of the end part of the electrode and
the corresponding ceramic protection.
3.2 REGULATION THERMOSTAT
“RMG Mk.II” boilers are equipped with a
regulating thermostat with a double con-
tact having differentiated setting (6 fig. 2).
This makes it possible to obtain a reduction
of heat output before the burner goes out
completely, by means of the coil assembly
installed on the gas valve regulator.
This step-modulation system affords the fol-
lowing advantages:
– higher overall boiler efficiency;
– containment within acceptable values of
the increase in temperature that takes
place in the cast-iron body (heat inertia)
when the burner goes out.
3.3 SMOKE SAFETY DEVICE
“70 - 80 - 90 - 100 Mk.II”
MODELS
This is a safety device against possible
smoke emission into the ambience (8 fig. 2).
The safety device goes into action by
blocking operation of the gas valve when the
return of the smoke into the ambience is
continuous and in quantities that might con-
stitute a danger.
To restart the boiler, the cover of the ther-
mostat must be unscrewed and reset the
underlying button.
Make sure the control panel is disconnec-
ted before carrying out this operation.
Should the boiler continue to “lock out”, it will
be necessary to make a careful check on
the flue pipe, making all the necessary modi-
fications and amendments so that it can
work properly.

4.1 GAS VALVE (fig. 10)
“RMG Mk.II” boilers come equipped stan-
dard with a HONEYWELL VR 4605 C gas
valve (for “70 - 80” models), VR 4605 CB
gas valve (for “90 - 100” models) and VR
420 PB gas valve (for “110” models).
When the boiler is ignited the first time, it is
always recommended to bleed the piping by
using the pressure outlet upstream from
the valve (7 fig. 10 - 9 fig. 2).
4.2 GAS VALVE ADJUSTMENT
“VR 4605 C - VR 4605 CB”
Calibration of the operating pressures is
done by SIME in the factory. Consequently
they should not be altered. Only when you
switch to another type of gas (butane or
propane) is it permitted to alter the opera-
ting pressures.
It is essential that this operation be car-
ried out exclusively by authorized techni-
cal staff.
When the working pressures have been
adjusted, reseal the regulators.
When the gas pressures are to be reset,
this must be done following a set order: first
the maximum pressure and then the mini-
mum.
4.2.1 Nominal pressure
adjustment (fig. 11)
To set the maximum pressure, proceed as
follows:
– connect the pressure column or a pres-
sure gauge to the pressure intake loca-
ted on the burner manifold;
– unscrew the screw (4) completely;
– set the knob of the thermostat to the
maximum value;
– supply electric power to the boiler;
– loosen the locknut (1) and turn the con-
nection (3):

done by SIME in the factory. Consequently
they should not be altered. Only when you
switch to another type of gas (butane or
propane) is it permitted to alter the opera-
ting pressures.
It is essential that this operation be car-
ried out exclusively by authorized techni-
cal staff. When the working pressures
have been adjusted, reseal the regulators.
When the gas pressures are to be reset,
this must be done following a set order: first
the maximum pressure and then the mini-
mum.
4.3.1 Nominal pressure
adjustment (fig. 11/a)
Connect the manometer to the pressure
test point located on the burner manifold,
turn boiler ON, and wait until a steady read-
ing on the manometer is obtained. Compare
this reading with that shown in Table 1. If any
correction is required, use an 8mm spanner
on the high pressure adjuster (1) turning
clockwise to increase, counter-clockwise to
decrease the pressure.
4.3.2 Reduced pressure
adjustment (fig. 11/a)
Turn the boiler OFF, and remove the plug
from the High - Low Coil. Turn the boiler ON
and wait until a steady reading on the
manometer is obtained. Compare this read-
ing with that shown in Table 1.
If any correction is required, use a 3.5 mm
flat blade screwdriver to rotate the low
adjust screw (2), turning clockwise to
increase and counter-clockwise to decrease
the pressure. When all adjustments are
completed, replace the plug on the coil, and
the cap over the adjustment screws.
4.4 GAS CONVERSION
To convert to butane gas (G30) or propane
gas (G31), the main nozzles must be repla-
ced with another supplied in the boiler gas
conversion kit, pressure regulator for “110
Mk.II” models and apply the LPG adaptor
code 6248301 onto the gas valve (5 fig. 10)
for “70 ÷ 100 Mk.II” models.
To adjust the operating pressures, refer to
section 4.2.
When the working pressures have been
adjusted, reseal the regulators.
After have ultimated the conversion of the
boiler, please stick onto the casing panel
the plate showing the relevant feeding gas
which is included into the conversion kit.
NOTE: After assembling all the gas con-
nections, a test for gas tightness must be
carried out using soapy water or special
products. Do not use naked flames. The
conversion to different gas must be car-
ried out exclusively by authorized techni-
cal personnel.
4.5 SHELL
DISASSEMBLY
Follow the steps described below to disas-
semble the shell (fig. 12):
– Remove the shell door (1) which is atta-
ched with pressure fit pins.
– To remove the cover (3) loosen the two
screws that attach it to the flue gas
chamber and lift.
– Remove the top front panel (2) placing it
against the flue gas chamber.
– Disassemble the left side (4) unscrewing
the nuts that attach it to the tie rods.
– Do the same operation to disassemble
the right side (5).
– Remove the inner wall (6) by pulling it
forward.
– Unscrew the nuts that secure the rear
wall (7) to remove it from the tie rods.
4.6 CLEANING AND
MAINTENANCE
At the end of each heating season, it is
essential to have the boiler thoroughly
checked and cleaned out.
Proceed as follows:
– Turn the main switch off to stop electric
power reaching the boiler and close the
gas feed cock.
– Remove the shell door and cover.
– Remove the top panel of the flue gas
chamber attached to it with self-threa-
ding screws.
– Remove the gas unit.
– Insert a special brush from the top into

of the burners to remove any dust. Make
sure that there are no scales on the top
drilled part of the burners (fig. 13).
– Remove any scales from the bottom of
the boiler and replace the items that
were removed, checking the position of
the gaskets.
– Check the chimney to make sure that
the flue is clean.
– Check operation of the equipment and
the main burner.
– After assembly of all the gas connec-
tions, these must be tested for sound-
ness, using soapy water or appropriate
products. DO NOT USE NAKED FLAMES.
Preventive maintenance and checking of
efficient operation of equipment and
safety devices must be carried out exclu-
sively by authorized technical personnel.
4.7 FAULT FINDING
The main burner does not ignite.
– This means that the flue smoke stat has
tripped off (point 3.3).
– Make sure power arrives to the gas
valve.
– Replace the electric operator of the
valve.
– Replace the valve.
The boiler reaches the set temperature,
but the radiators do not heat up.
– Make sure there are no air bubbles in the
system, if so purge from appropriate air
vents.
– The room stat is too low or must be
replaced if faulty.
– The connections of the room stat are not
correct (make sure the cables are placed
on terminals 6 and 7 of the boiler termi-
nal board).
Boiler operates only at nominal pressure
and does not reduce pressure.
– Check whether there is voltage at both
ends of coil.
–
The coil has a break in the winding; replace.
– The rectifier card that supplies the coil is
interrupted; replace.
– There is no differential on setting of the
two contacts of the regulating thermo-
stat; replace.
– Check calibration of reduced pressure
adjusting screw of coil assembly.
The boiler gets dirty easily causing scaling
of cast iron exchanger and cutting off of
smoke stat.
– Check that the flame of the main burner
is well regulated and that gas consump-
tion is proportional to boiler output.
– Poor ventilation of premises where boiler
is installed.
– Flue with insufficient draught or not mee-
ting requirements.
– The boiler works at too low temperatu-
res. Adjust the boiler thermostat to
higher temperatures.
Thermostat switches boiler back on with
too high temperature difference.
– Replace regulating thermostat since it is
out of calibration.

BOILER IGNITION
Open the gas valve and press the main swit-
ch to ignite the “RMG Mk.II” boiler (fig. 14).
TEMPERATURE
ADJUSTMENT
The heating temperature can be adjusted
by turning the knob of the thermostat,
which has a range of between 40°C and
85°C. The temperature setting can be
checked on the thermometer. To ensure
optimal boiler efficiency at all times, we
recommend not to drop below a minimum
working temperature of 60°C. In this way,
any formation of condensate that might
cause deterioration of the cast-iron body
over time will be avoided (fig. 15).
SAFETY THERMOSTAT
The safety thermostat is of the manually
resetting type and opens, causing the main
burner to turn off immediately, whenever
the temperature of 95°C is exceeded in the
boiler. To restore boiler operation, unscrew
the black cap and reset the button (fig. 16).
Should the appliance again “lock out”,
please approach the authorized technical
staff.
SMOKE SAFETY DEVICE
“70 - 80 - 90 - 100 Mk.II” MODELS
This is a safety device against possible
smoke emission into the ambience.
The safety device switches off the gas valve
when the return of the smokes into the
ambience is continuous and then dange-
rous.
To restart the boiler, the cover of the ther-
mostat must be unscrewed and then press
the underlying button (fig. 17).
Should the boiler “lock out” again, you
must call the authorized technical staff.
WARNINGS
– In case of fault and/or incorrect equipment operation, deactivate it, without making any repairs or taking any direct
action. Contact the nearest Authorised Technical Service Centre.
– The installation of the boiler and any servicing or maintenance job must be carried out by qualified personnel. Under
no circumstances, the devices sealed by the manufacturer can be tampered with.
– It is absolutely prohibited to block the intake grilles and the aeration opening of the room where the equipment is
installed.
