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
calibrated between High and Low in five intermediate
settings, corresponding to a temperature range of 82°C
(high) to 60°C (low).
Set the temperature by turning the knob to the required
temperature. However, the installer should take into
consideration that the return water temperature must not
drop below 60°C when the appliance is up to full operating
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.
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 the front panel and
push in button.
Note: The limit thermostat can only be reset when the
water temperature has dropped at least 20° C.
BURNER LOCK-OUT
If the burner fails to light, it will go to lock-out. If this
occurs, wait about one minute then remove the front
panel and press illuminated reset button to start burner.
In the event of the burner not firing wait a further minute
and then press the reset button again. If the burner still
fails to start, switch off the electrical supply to the boiler.
WARNING - DO NOT ATTEMPT TO START BURNER
MORE THAN TWICE
(See Simple Fault Finding before contacting your
Service Engineer).
1. USERS INSTRUCTIONS
All boiler controls are located behind the front casing
door panel. This is opened by pulling at the bottom
edge towards you.
The Trianco EuroStar WM has been designed and con-
structed to give you years of trouble free service and
these instructions are provided to assist you in obtaining
the best performance with the least trouble and cost.
The boiler is fully automatic in operation and requires lit-
tle attention other than the setting of the thermostat and
any system controls such as a room thermostat and time-
switch.
TO FIRE THE BOILER
Before firing the boiler, ensure the system is full of water,
there is sufficient oil in the storage tank and all valves are
open.
1. Check that the Time-switch/Programmer (if fitted) is
ON and the room thermostat is calling for heat.
2. Set the boiler thermostat to the desired temperature.
3. Switch on the electrical supply to the boiler and the
burner should fire after a few seconds of fan
pre-purge.
4. Set the Time-switch/Programmer (if fitted) to the
times and programme required.
5. 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 ‘O’
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.

2
Sludge and water caused by condensation should be
drawn off at the tank 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 for a blown fuse. If the fuse has blown and on
replacement blows again, switch off the mains
electrical supply to the boiler and call your Service
Engineer.
3. Check that there is adequate oil in the tank and the
shut-off valves are open.
4. Check for burner lock-out. Press the reset button
and burner should fire. DO NOT PRESS MORE
THAN TWICE. Refer to ‘Burner lock-out’ for further
advice.
5. Check for excess water temperature (Refer to ‘High
Limit Thermostat’ for advice).
Note: If the boiler has been off as a result of a power
failure, it will be necessary to reset 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 a qualified engineer and an annual service is given
thereafter, preferably by an OFTEC trained and
registered engineer.
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.

SYSTEMS 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.
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 to an hour before it 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
If the boiler and central heating is shut down for many
hours during very cold weather, the water may be in
danger of freezing and, as such, it is advisable to protect
the installation with a frost thermostat.
Where the system is not protected, the boiler should be
left switched on and the room thermostat set to a low
setting e.g. 7° C (45° F) to prevent the building tempera-
ture falling too low.
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 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 2869:1983 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.

Siting the Boiler (Sound Levels)
The following aspects should be considered before
installation:
(a) Some people are particularly sensitive to even low
noise levels so this aspect should be discussed with
the householder.
BOILER CLEARANCE REQUIRED
TOP 200mm
SIDE 5mm
BOTTOM 60mm
Fig. 2
(b) Small rooms tend to amplify noise, particularly if the
wall construction is hollow or the surface tiled.
(c) A chimney passing through a bedroom can some
times transmit noise.
(d) Low level flue terminals produce some exhaust
noise, so care should be taken when siting adjacent
to neighbouring property, patios and play areas.
Clearance and Service Access
When siting the boiler, ensure adequate clearance is
allowed for making water and flue connections. The boiler
can be fully serviced from the front.
Unpacking the Boiler
(a) Cut through straps and remove carton.
(b) Remove the front door, remove pack of parts, lift outer
casing from boiler and move to a safer place to avoid
damaging.
(c) Remove securing screws fixing boiler to pallet.
(d) The boiler can now be removed from pallet.
Fixing Boiler to the wall
(a) The boiler should be fixed to a suitable load bearing
wall using fasteners supplied. If these are not suitable,
then a equally strong and secure fastening may be used.
(b) Using the template supplied, work out the position of
the boiler, fix template to the wall and drill 3 holes of a
diameter of 6mm to a depth of 38mm. Fit plastic plugs
provided, cut hole 200mm x 200mm in the wall to take
terminal, remove template and fit wall mounting
bracket to wall using screws provided.
(c) Splitting the burner at this point and removing the
main burner body (leaving the blast tube in position)
will make it easier for hanging the boiler on to the wall
mounting bracket. (refer to Fig.10, servicing the burner).
(d) Hang the boiler on to the 2 lugs on the wall mounting
bracket, then drill through 1 of the 2 mounting holes
on the oil pipe bracket, fit a plastic wall plug and screw
back to the wall.
(e) Re-assemble burner, connect oil lines.

Electrical Supply
230V 1 Phase 50Hz (Fused 5 Amp)
Note: THIS APPLIANCE MUST BE EARTHED
All electrical wiring must be carried out by a qualified
electrician in accordance with current I.E.E. Regulations
and any Local Regulations that may apply.
The 230v - 50 Hz electrical supply must be fused by a
double pole switch with a contact separation of at least
3mm in both poles, and shuttered socket outlet (both
complying with the requirements of BS 1363) adjacent to
the boiler. Fuse supply at 5A. The minimum requirement
for the power supply cable should be a PVC sheathed
flexible cord, at least 0.75mm2(24 x 0.2mm) (code
designation H05 VV-F or H05 VVH2-F) as specified in
table 16 of BS 6500.
This appliance MUST be earthed and the electrical
supply earth cable must be of a greater length than the
current carrying conductor cables (ie live and neutral

Ventilation
Although no openings are required for the supply of
combustion air (this comes from outside through the air
duct system direct to the burner), ventilation is, however,
necessary if the boiler is installed in a compartment or a
confined space in order to prevent overheating of the
boiler controls (see Fig. 4 for ventilation openings).
MAKE SURE ALL UNUSED BOILER TAPPINGS ARE
PLUGGED BEFORE FILLING THE SYSTEM.
Flush out the system to remove swarf or residues
before fitting circulating pump.
4. OIL SUPPLY
Oil
The oil burner is factory set to burn 28 sec. Kerosene
to BS 2869.
Oil Storage Tanks
Size and Location of Tank
The tank should be large enough to allow for economic
deliveries and be located in the most unobtrusive
position, having regard to the need for safety, filling,
maintenance (if steel tank) and the head of oil required.
Whilst it is highly unlikely that a fire could start from an
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 from a
building, nor closer than 760mm from a site boundary.
Where a tank has to be less 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.

9
All oil line 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 line can be fed into the back of the boiler base tray
or through the holes at the side.
Single pipe oil supply (Fig. 6 )
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.
Two pipe oil supply (Fig. 7)
Where, the bottom of the oil storage tank is below the
burner, a two pipe suction lift system is necessary.
When using a two pipe system, it is important that the
by-pass plug (supplied with burner) is fitted, in the pump
as shown in separate burner details leaflet. An additional
flexible hose is also required.
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 also be fitted in
the line.
No valves are permitted in the return line which must
remain unobstructed at all times.
Notes:
(1) The pump suction should not exceed 0.4 bar, other
wise dissolved gas will be released from the oil to
affect combustion.
(2) The return pipe must end at the same level as the
suction outlet to prevent loss of prime.
(3) The outlet from 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, an Oil De-
aerator can be used. The burner is piped as for a two
pipe system up to the Oil De-aerator but only a single
pipe is required to be run back to the oil storage tank.
Anone-return valve is not required with this system but
the bypass plug must be fitted in the pump as for a two
pipe system.
The Oil De-aerator which should be fitted close to but not
inside the boiler casing, is available from most Builders
Merchants and some Oil Tank manufacturers.
Alternatively, a non-combustible radiation barrier must be
provided which meets the requirements of BS 5410
Part 1: This standard applies to tanks up to a capacity of
3,400 litres which is deemed the maximum size for a sin-
gle family dwelling.
Steel Tanks
Steel tanks should comply with the requirements of
BS 799, Pt. 5 and be mounted on brick or block piers with
a waterproof membrane between the piers and tank.
The tank should be fitted with fill and vent connections
(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 lower
weight.
(d) They have a 10 year manufacturer’s guarantee.
Plastic tanks should be fitted with similar components to
those used with steel tanks.
Fire Protection
To comply with building regulation Section J5:
1Where a storage tank is close to a dwelling, fire
cladding must be provided to the eaves, if less than
1.8m from the top of the tank.
2The cladding must extend 300mm beyond the tank.
3The tank must be sited on a non-combustible base.
Pollution Protection
To comply with building regulation section J6, the tank
must be ‘bunded’ (i.e. double walled) if:
1The tank is less than 10m from a stream.
2The tank is less than 50m from a well, spring, or drinking
water.
3The tank cannot be viewed from the delivery point.
4In the event of a leak, there is a risk of oil reaching a
manhole cover or drain.
5 The tank capacity exceeds 2500 Litres.
Oil supply line
Along life flexible oil hose, filter and shut-off valve are
supplied with the boiler.
The oil shut-off valve should be fitted as close to the
burner as practicable to enable the burner to be
disconnected without undue loss of oil. The filter must be
connected in the oil supply pipe and positioned either
inside or outside the building.
Fire Valve
Afire-valve must be fitted in the oil line outside the
building with its sensing phial positioned within the boiler
casing below the control panel. A clip is provided for
retaining the phial.

(a) Location (Fig. 9)
Modern balanced flue boilers are designed to
operate at low noise levels. However, when
positioning your boiler, it is not recommended to
have the terminal facing a neighbours property
or patio etc. It should also be positioned to avoid
products of combustion entering the building.
(b) Flue Sealing
As the flue system operates under positive
pressure, it is essential to seal all flue joints.
Apply a thin bead of silicone sealant (supplied)
around the flue pipe spigot before inserting into
socket and all other joints.
(c) Fuel
Only Kerosene 28 sec. Class C2 is permitted for
boilers using low level flue discharge.
(d) Important
Trianco Balanced Flue Kits have been designed
primarily to use with Trianco boilers and as such
compatibility with other makes of boiler cannot
be guaranteed.
5. BALANCED FLUE SYSTEMS
(optional extra)
The Trianco balanced flue system offers much greater
flexibility for siting, the boiler compared with a
conventional chimney. The only requirement is for a
suitable outside wall to fit the horizontal discharge
terminal, or alternatively, a single storey roof for a vertical
discharge.
In addition to the siting benefit, the performance of
balanced flue boilers is virtually unaffected by high wind
conditions since the wind pressures are applied equally
to both air intake and flue gas discharge, thus creating a
balanced condition.
Whereas some balanced flue boilers rely on case sealing
to achieve a room seal, Trianco boilers have a sealed air
duct system which maintains the room sealed
performance even when the casing door is removed for
burner commissioning or adjustments.
The use of the balanced flue principle also enhances the
overall thermal efficiency of the boiler since the incoming
air extracts waste heat from the flue and returns it as
pre-heated air to the burner where it aids combustion.
The high-level kits have an additional benefit in that the
flue noise is reduced due to the coaxial arrangements of
the air and flue pipes - the flue being surrounded by an
air space forms an effective acoustic barrier.

600mm HORIZONTAL TELESCOPIC BF KIT
ASSEMBLY METHOD (Fig 10/11)
1. Having decided the position of the boiler cut a
hole 170mm square in the wall. Secure the boiler in
position without casings and slide the flue box through
the cut-out in the wall and affix to the top of the air box
using four self-tapping screws (provided).
2. Fit the flue elbow to the stainless steel pipe on the
terminal. Slide the terminal into the flue box from the
outside and locate the elbow over the spigot plate..
3. Measure from the face of the outside wall to the end
of the terminal. Subtract 150mm. This will give the
length that requires cutting from the terminal inner
pipe.
4. Remove the terminal form the flue box, remove the
elbow from the pipe and then cut the terminal pipe to
the required length. Replace the elbow in the end of
the pipe and slide the terminal into the flue box,
locating the elbow securely onto the spigot.
5. When terminating from the rear of the boiler, fit the air
hose spigot over the hole in the L-shaped blanking
plate, securing it with the M4 wing nuts provided.
When terminating from the side of the boiler, fit the air
hose spigot to the side of the flue box.
6. Fit the L-shaped blanking plate to the flue box. Blank
off the remaining holes with the round sealing plates,
using silicone sealant and the M4 wing nuts.
7. Fit the air hose between the burner and the spigot on
the flue box, securing it using the clips provided.
8. Close any gaps around the terminal on both sides of
the wall and replace the top casing in position. Please
note that a terminal guard will be required if the
terminal exhausts less than 2 metres from ground
level.
Trianco flue kits are designed to incorporate the latest ‘O’-ring seals.
Before commencing assembly, please make sure that all ‘O’-rings seals are in position.
