HEALTH AND SAFETY
INFORMATION FOR THE INSTALLER AND SERVICE ENGINEERS
Under the Consumer Protection Act 1987 and the Health and Safety at Work Act 1974, it is a
requirement to provide information on substances hazardous to health (COSHH Regulations
1988).
The Company takes every reasonable care to ensure that these products are designed and con-
structed to meet these general safety requirements, when properly used and installed.
To fulfil this requirement products are comprehensively tested and examined before despatch.
This appliance may contain some of the items below.
When working on the appliance it is the Users/Engineers responsibility to ensure that any neces-
sary personal protective clothing or equipment is worn appropriate to parts that could be consid-
ered as being hazardous to health and safety.
INSULATION AND SEALS
Glass Rope, Mineral Wool, Insulation Pads, Ceramic Fibre, Glass Insulation.
May be harmful if inhaled. May be irritating to the skin, eyes, nose or throat. When handling avoid
inhalation and contact with eyes. Use (disposable) gloves, face masks and eye protection.
After handling wash hands and other exposed parts. When disposing, reduce dust with water
spray, ensure parts are securely wrapped.
GLUES, SEALANTS & PAINT
Glues, Sealants and Paints are used in the product and present no known hazards when used in
the manner for which they are intended.
KEROSENE & GAS OIL FUELS (MINERAL OILS)
1. The effect of mineral oils on the skin vary according to the duration of exposure.
2. The lighter fractions also remove the protective grease normally present on the surface of the
skin rendering the skin dry, liable to crack and more prone to damage caused by cuts and
abrasions.
3. Skin rashes (oil acne). Seek immediate medical attention for any rash, wart or sore
developing on any part of the body, particularly the scrotum.
4. Avoid as far as possible any skin contact with mineral oil or with clothing contaminated with
mineral oil.
5. Never breathe any mineral oil vapours. Do not fire the Burner in the open i.e. out of the Boiler
as a misfire will cause unburnt oil vapours.
6. Barrier cream containing lanolin such as Rosalex Antisolv, is highly recommended together
with a strict routine of personal cleaning.
7. Under no circumstances should mineral oils be taken internally.

BOILER CONTROL THERMOSTAT
The boiler control thermostat enables you to select the
temperature of the water leaving the boiler. It is calibrat-
ed between High and Low in five intermediate settings,
corresponding to a temperature range of 82° C (high) to
55° C (low).
Set the temperature by turning the knob to the required
temperature. However, the installer should take into con-
sideration that the return water temperature must not
drop below 56.2° C when the appliance is up to full oper-
ating temperature.
The thermostat is switched off when the knob is turned
fully anti-clockwise with pointer opposite ‘O’
HIGH LIMIT THERMOSTAT
(Hand Reset)
The high limit thermostat is factory set and requires no
adjustment. Should the boiler thermostat malfunction,
the limit thermostat will take over and shut down the boiler,
thus leaving the overheat neon light illuminated (see Fig
1 for position).
If the limit thermostat operates frequently, consult your
Service Engineer as there may be a fault in the system.
To reset the limit thermostat, remove all the inside door
panel and push reset button.
Note: The limit thermostat can only be reset when the
water temperature has dropped at least 20°C.
SYSTEM CONTROLS
ROOM THERMOSTAT
The room thermostat should not be positioned near a
source of heat such as a radiator or exposed to the sun
as this will cause the central heating to switch off before
the room is up to temperature. Follow the manufacturer’s
instructions for best siting position for the thermostat.
1 USERS INSTRUCTIONS
All boiler controls are located behind the front casing
door panel. This is opened by pulling the bottom
edge towards you.
The Trianco EuroStar WM 50/65 In The Wall Boilers have
been designed and constructed to give years of trouble
free service and these instructions are provided to assist
you in obtaining the best performance with the least trou-
ble and cost.
The boiler is fully automatic in operation and requires
little attention other than the setting of the thermostat and
any system controls such as a room thermostat and
time-switch.
TO FIRE THE BOILER
1 Before firing the boiler, ensure the system is full of
water, there is sufficient oil in the storage tank and all
valves are open.
2 Check that the Time-switch/Programmer (if fitted) is
ON and the room thermostat is calling for heat.
3 Set the boiler thermostat to the desired temperature.
4 Switch on the electrical supply to the boiler and the
burner should fire after a few seconds of fan pre
purge.
5 Set the Time-switch/Programmer (if fitted) to the times
and programme required.
6 The boiler will now operate automatically, cutting in
and out according to the heat demand.
TO STOP THE BURNER
The burner may be stopped by turning the Boiler Control
Thermostat fully anti-clockwise to the OFF position ‘0’.
If the boiler is to be off for a long time, it is recommended
that the mains supply to the boiler is switched off or the
Time-switch/Programmer (if fitted) is switched to the OFF
position.

TIME-SWITCH PROGRAMMER
When choosing the operating times for your boiler, it is
useful to remember that central heating usually takes
between half an hour before is becomes effective.
It is suggested that the Time-switch/Programmer is set to
bring on the heating about an hour before heating is
required.
It is also worth noting that the heating system will usually
remain effective for up to half an hour after boiler shut-
down. The timer can therefore be switched off earlier as
an economy measure.
FROST PROTECTION
The boiler is fitted with a frost thermostat, which will acti-
vate the burner should ambient temperature fall to 5° C,
the thermostat will automatically cut off on temperature
rise. There is no manual adjustment.
Note: The phial is to be located in a clip provided on the
rear of the boiler mounting plate.
If the system is shut down for a long period during very
cold weather, it is advisable to completely drain the system.
However, frequent draining should be avoided, especially
in hard water areas, as this could lead to scaling of the
boiler waterways.
SHUTTING DOWN FOR THE SUMMER
If the boiler is shut down for the summer months, it is
advisable to have it serviced and thoroughly cleaned as
soon as possible to minimise corrosion of the heating
surfaces.
OIL
The recommended oil for your boiler is 28 sec. Kerosene
(BS 2869: Class C2)
OIL TANK
Always ensure the tank is topped up at regular intervals,
do not wait until the tank is nearly empty before refilling,
otherwise sludge and water could be sucked into the oil
pipe to affect the burner’s operation and reduce pump life.
After a delivery of oil, it is recommended that the oil is
allowed to settle in the tank for about half an hour before
restarting the burner.
Sludge and water caused by condensation should be
drawn off at the drain-cock annually.
SIMPLE FAULT FINDING
If the burner fails to start for no apparent reason, make
the following checks before calling your Service
Engineer.
1 Check for failure in the electrical supply, e.g a power cut.
2 Check that there is adequate oil in the tank and the
shut-off valves are open.
Note: If the boiler has been off as a result of a power
failure, it will probably be necessary to re-set the Time-
switch/Programmer to the correct time unless it has a
built-in power reserve.
SERVICING
To ensure efficient and reliable operation of the boiler, it
is essential that the oil burner is initially commissioned by
an OFTEC trained and registered engineer and an
annual service is given thereafter.
Notes:
ELECTRICAL SAFETY CHECKS SHOULD BE
CARRIED OUT BY A QUALIFIED ELECTRICAL
ENGINEER
(a) It is the responsibility of the Installer to ensure
proper commissioning is carried out.
(b) It is a requirement of the boiler’s guarantee and
any extended warranty that an annual service
is carried out by a qualified engineer.

When locating the boiler, care should be taken in respect
of the flue terminal which should be within the parameters
laid down within Fig 3
Due care and attention is required when siting the boiler
not only during installation but for subsequent servicing.
The black outside casing of the boiler shall not be less
than 1 metre form the ground. A sensible maximum
height for installation is 2.5 metre from the terminal.
Boilers installed above this height must have provision
made for the health and safety of the service engineer.
Modern boilers are designed to operate at low noise levels.
However, when positioning your boiler it is not
recommended to have the terminal facing a neighbour’s
property or patio etc. It should be positioned to avoid
products of combustion entering the building. See fig. 3
a) With the template provided, mark out the proposed
hole in the chosen wall. The dimensions allow for a
tolerance of 5mm all round. It is recommended that
a cutting disc is used to remove surplus brick and
blockwork; this will ensure a uniformed aperture
opening. Care should also be taken to ensure that
the prepared aperture is parallel.
b) Insert inner wall duct together with internal mounting
plate through aperture in wall, hold centre and mark
fixing points (8) through holes in boiler mounting
plate, drill (DIA12 x 50 DEEP) and plug using screws
supplied. Affix assembly to wall, leaving screw loose
to allow fitment of external duct.
c) Insert external duct over internal duct, holes to bottom.
Adjust from wall thickness ensuring a minimum of
40mm from wall face to front of sleeve; this is to
allow for the fitment of oil line bulkhead fittings,
valves and combustion air valves. On completion,
secure all screws. Slide trim over sleeve, mark and
drill holes. 3-holes 12 Dia x 50mm deep
deep. Before fixing trim to wall, ensure wall is made
good and finally secure trim to wall. Silicone should
also be applied to area. See Fig. 2
CAUTION:
The heat exchanger weighs 49kg max, and requires
two people to lift into position.
When fitted, the heat exchanger is secured in place
by 3 x M8 flange nuts.
Water Connection
The boiler has two 22mm compression connections iden-
tified on wall frame (supplied with nut and olive). Left
hand return right hand flow (viewed form inside
building/dwelling).
There is also a 1/2'' BSP drain cock tapping located on
the bottom front of heat exchanger (viewed from outside
building/dwelling).
The boiler must be used on a fully pumped
system only.
7
Note (1) The terminal should be positioned so as to
avoid products of combustion entering the
building.
Note (2) If the terminal is less than 2 metres above the
ground level, balcony or place to which any
person has access, the terminal must be
protected by a guard.
Note (3) If the terminal is fitted within 850mm of plastic
or painted gutter or within 450mm of painted
eaves a heat protection shield should be fitted
to the underside of the gutter of eaves.
Note (4) The flue must be positioned so that it does not
cause nuisance and permits the dispersal of
combustion products.

FIG. 4 OIL LINE DETAILS
External
Baffles should be re-fitted ensuring correct position of
baffle prior to inserting baffle cassette which is retained
by 4 x M6 wing nuts (see diagram, Fig 12).
External oil line connections should be made using the
holes provided in base of outer sleeve.
Kit consists of:
2 x 1/4'' BSP Lock Nut
1 x Female/Female Elbow 1/4'' BSP
1 x 3/8'' x 1/4'' bulkhead fitting
1 x 3/8'' None Return Valve
The boiler is factory fitted for 1 pipe oil line or de-aeration.
Should it be necessary to employ a two-pipe system, see
diagram on data sheet.
Important:
The isolating valve should be fitted on the flow pipe (see
oil line details, Fig 4) Fire valve sensing phial should be
located into clip provided above burner.
Burner can now be fitted prior to commissioning.
Ensure electrical lead from burner is plugged into the
socket connector on control panel.
When fitting the flue terminal, the actual terminal should
protrude through the external door a minimum of 65mm.
Once the dimensions have been determined the flue
should be siliconed into position. NB The boiler can be
test fired and subsequently commissioned with the
external door removed.

Oil
The oil burner is factory set to burn 28 sec. Kerosene to
BS 2869.
Note: Only kerosene is permitted for low level flue
discharge.
Oil Storage Tank
Size and Location of Tanks
The tank should be large enough to allow for economic
deliveries and be located in the most unobtrusive
position, having regard to the need of safety, filling,
maintenance (if steel tank) and the head of oil required.
Whilst it is highly unlikely that a fire could start from a oil
tank, it does however need to be protected from a fire that
may originate in a nearby building. The tank should
therefore not be located nearer than 1.8 metres, the
building wall must not have any openings other than
small ventilation openings. The wall shall have a half
hour resistance to an internal fire and extend 1.8 metres
from any part of the tank.
Alternatively, a non-combustible radiation barrier must be
provided which meets the requirements of BS 5410. This
standard applies to tanks up to a capacity of 3,400 litres.
Steel Tanks
Steel tanks should comply with the requirements of
BS799, Pt.5 and mounted on brick or block piers with a
waterproof membrane between the piers and tank.
The tank should be fitted with the fill and vent connection
(weather protected), a drain-off cock, shut off valve and
an oil level indicator.
Plastic Tanks
Polyethylene tanks are now widely used because of their
advantages over traditional steel tanks:
a) They do not need pier supports and can be mounted
directly on any flat surface giving uniform support for
the tank base
b) They do not corrode and therefore never need painting.
c) They are easier to handle because of their weight.
d) They have a 10 year manufacturer’s guarantee.
Plastic tanks should be fitted with similar components to
those used with steel tanks.
Oil Supply Line
One long life flexible oil hose, filter and shut-off valve are
supplied with the boiler.
The oil shut-off valve should be fitted as shown to enable
the burner to be disconnected without undue loss of oil.
The filter must be connected in the oil supply
pipe and positioned outside the building. (Fig.4)
Fire Valve
a fire-valve must be fitted in the oil line outside the building
with its sensing phial positioned within the burner
compartments. clip is provided for retaining the phial
above the burner.
All oil joints must be completely sealed and the total pipe
run thoroughly flushed out before connecting to the burner.
No soldered joints are permitted in the oil line.
The oil lines are fed into the boiler through pre-punched
holes in the bottom edge of the outer wall duct. An oil line
connection kit is provided (see Fig 4)
Two pipe Oil Supply (Fig 5)
Where the bottom of the oil storage tank is below the
burner, a two-pipe suction lift system may be necessary.
Aspring loaded non-return valve must be fitted in the
suction line to stop the oil running back to the tank.Afilter,
shut-off valve and fire valve must be fitted in the line.
No valves are permitted in the return line which must
remain unobstructed at all times.
Notes:
The pump suction should not exceed 0.4 bar, otherwise
dissolved gas will be released form the oil to affect
combustion.
The return pipe must end at the same level as the suction
outlet to prevent loss of prime.
The outlet form the tank should be approximately 75mm
(3 in) above the bottom to prevent sediment and water
being drawn into the supply pipe.
Oil De-aerator- Single Pipe Supply (Fig.6)
Where a two-pipe suction lift system is required , but the
return pipe is too long, or impractical to run., a de-aerator
can be used. The burner is piped as for a two-pipe system
up to the De-aerator but only a single pipe is required to
be run back to the oil storage tank. A non-return valve is
not required with this system. The burner is factory set
for two pipe systems.
The De-aerator, which should be fitted close to the boiler
externally, is available from most Builders Merchants and
some Oil Tank manufacturers.
Single Pipe oil Supply (Fig 7)
When the bottom of the oil supply tank is above the burner,
a single pipe gravity system can be used. The oil supply
pipe must be connected to the suction port on the burner
pump via the flexible hose. The return port must be
blanked off with plug supplied and the C washer fitted
(refer to burner instruction leaflet for more information).
When the tank is below the burner a none return valve
must be fitted, see Fig. 4

7. SERVICING
To maintain the boiler’s high thermal efficiency and
reliable operation, it should be serviced annually by a
qualified engineer preferable OFTEC trained and
registered.
Electrical work should be carried out by a qualified
electrical engineer
Note: It is a requirement of the boiler’s guarantee that an
annual service is carried out by a qualified engineer.
If the boiler is used to provide central heating and hot
water all year round, the best time for its annual service
is just before the start of the heating season.
Oil Tank
Open tank drain-cock to draw off any accumulated water
and sludge.
Line Filters
Turn off oil supply and remove filter bowl. Wash filter ele-
ment clean with kerosene.
Electric Cables
Check for breaks in the insulation and replace if worn.
Servicing the burner
Note: When servicing the boiler it is recommended this is
undertaken in dry conditions and that all safety rules are
observed.
1) Remove external cover (item 13) by removing (a) 4
plastic plugs and (b) 4 self tapping screws
2) Isolate electricity by means of service switch
3) Turn off oil by means of isolation valve fitted to the oil
supply line.
4) Remove 4mm screw retaining burner to blast tube
assembly, withdraw burner. Refer to burner details.
5) Remove and fit new nozzle to same specification; do
not attempt to clean or dismantle nozzle.
6) Clean ignition electrode, examine porcelain insulators,
replace electrodes if there are any cracks or signs of
crazing. Finally, adjust and set electrodes in accordance
with instructions given in burner details leaflet.
7) Remove photo cell and carefully clean glass face.
8) Clean deposits form impellor blades and check
impellor is tight on motor shaft.
9) Check conditions of pump dog and motor dog and
coupling, replace if necessary
10) Clean area around air intake and air slide, check
setting and free movement of air band (4mm allen key)
11) Prior to refitting burner, remove head from boiler (single
screw retains head to mounting,) clean and replace
after checking condition of gasket.
12) Prior to replacing burner remove cap form oil pump
(4 x 4 mm allen screws), clean filter and reassemble.
Note: we recommend the burner be fitted after the
baffles have been checked and replaced.
13) Reassemble burner after checking condition of gasket
between burner and head assembly, replace as
necessary
14) Check condition of flexible oil hose(s) for oil leaks
and replace with a similar long life hose supplied with
the boiler
Service the boiler Burner removed
1 Remove baffle cassette (retained by 4xM6 wingnuts),
clean by removing any light deposits.
NB Flue terminal is attached to cassette , if the boiler
is installed to its maximum extension it may be
necessary to remove the terminal assembly.
Store carefully to avoid damage.
2. Brush all deposits form Flue baffle and internal
surfaces of the boiler.
3 Remove flue deposits form the combustion chamber
using a vacuum cleaner.
Note
Provided within the wall duct is a 3 pin socket, this is
fused 5 amp and must only be used for vacuum
cleaner or inspection lamp.
4 Replace flue baffle in position as shown (Fig 12) refit
baffle cassette after checking seal, fully tighten wing
nuts and replace flue terminal if removed, check
gasket prior to refitting.
After fitting complete assembly check that terminal
protrudes 65mm minimum through the front access
cover. (item 13)
5 Refit burner to boiler, check position of gasket (not
trapped).
6 Turn oil supply on.
7Switch on electricity via service switch.
8 The burner can now be checked in respect of
combustion setting (see separate burner data sheet
for combustion settings).In order to undertake the
above checks the service switch must be in the
SERVICE position, on completion of the service the
switch is returned to the RUN position.
9When the service switch is in the service position, the
water circulator does not run.
10 Replace outer cover (item 13) after checking seal,
replace self tapping screws and plastic cover (item
14 + 15), recheck flue terminal position, should be
min 65mm form face of outer cover item 13.

8. COMMISSIONING
It is the responsibility of the installer to ensure the boiler
is properly commissioned, failure to do so will make the
boiler’s guarantee and any extended warranty null and
void.
Although all burners are factory tested before
despatch, it is recommended that the boiler is
commissioned in accordance with the data provided
in the separate burner data sheet.
Procedure
1Switch off electricity supply to boiler by means of the
boiler service switch. It is however recommended
that the electrical supply be totally isolated whilst the
initial commissioning checks are made. During
commissioning the boiler can be operated via the
service switch in the Service Mode. Once the
commissioning has been completed this switch
should be returned to the RUN position prior to
handing over.
2 Ensure boiler is full of water and all valves are open.
3 Remove flue-cover and check that flue-baffle is
correctly positioned (see Diagram for baffle
arrangement)
4 Disconnect oil hose form burner, open shut-off valve
and run off a quantity of oil into a container to check
for a clean air free supply then reconnect the hose.
(This applies to a single pipe gravity system only).
5 Check that the time-switch (if fitted) is in the ON position
and room and boiler thermostats are calling for heat.
6 Switch on electrical supply and the burner should
start. (See item 1) Note : The burner may lock-out
on first firing due to air in the pump, if this happens,
wait about a minute before pressing reset button to
restart burner. If a further lock-out occurs, the air
should be bled form the pump pressure gauge
connection.
7 Cycle the burner two or three times until the flame
cuts off sharply - this indicates any remaining air has
been dispersed.
8Allow the burner to run for about 15 minutes, then
take a CO2reading form the end of the terminal
silencer. Compare the reading with that given under
‘Burner Settings’ and adjust the air settings if
necessary to achieve the required CO2%. Also,
check the smoke and flue gas temperature.
Air Adjustment
The air damper is factory set at a nominal position to suit
typical balanced flue conditions. However because of
variations in the site location, it will be necessary to slightly
adjust the air damper in order to achieve the CO2 level
indicated on ‘Burner Leaflet’
The adjustment can be carried out by removing the end
cover form the burner and using a 4mm Allen Key rotate
screw 16 - clockwise to increase air lowering the CO2
and anti clockwise to raise CO2.
Handing Over
After completing the boiler installation, the installed
should make a thorough check of the system to ensure it
is completely satisfactory and demonstrate to the user
the operation of the boiler and any system controls.
All instructions should be handed to the user for retention
and advice given regarding the need for annual servicing.
