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 is fully adjustable allowing
you to select the required temperature of the water leaving
the boiler.
The boiler thermostat operates between 55°C (low) and
82°C (high).
Note: Where a cylinder thermostat or room thermostat is
fitted ensure that the boiler thermostat is set above or
equal to the highest setting.
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. The red light will illuminate when limit thermostat
has operated.
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 has failed to light, the boiler will go into lock-out
mode. The illuminated reset button on the burner control
box will indicate this. To reset the burner press the
illuminated reset button. In case of the burner not firing
and the boiler returning to lock-out mode, 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. USER INSTRUCTIONS
HOW TO USE YOUR TRIANCO
BOILER
The Trianco EuroStar Condensing boiler has been
designed and constructed to give years of trouble free
service. These instructions are provided to assist you in
obtaining the best performance with the least trouble and
cost.
The boiler will provide both domestic hot water and
central heating with the simplest of controls.
The boiler is supplied with adjustable boiler control
thermostat, manual reset high limit thermostat and an
option for fitting a programmer kit.
On the control panel there are three neon indicator lights.
(See Fig 1 below)
Green - Power on to the boiler
Amber - Boiler is calling for heat
Red - Limit Thermostat Light
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. The green
and amber neon lights will illuminate 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.

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 Kerosene C2 to
BS 2869.
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 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 be commissioned on
installation. The boiler requires an annual service
thereafter.
A qualified Oftec trained and registered engineer must
carry out all commissioning and service work.
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.

or
•Where the appliance falls outside the guarantee
period (see terms and conditions enclosed).
or
•The appliance has not been correctly installed,
commissioned or serviced as recommended (see
commissioning, installation and servicing
instructions)
or
•The breakdown occurs immediately following an
annual service visit. In this instance your appointed
Service Agent must check all his work PRIOR to
requesting Trianco to attend.
NOTE: Burner nozzles are currently guaranteed
until the first service.
Over 50% of all service calls made are
found to have no appliance fault.
What to do in the event of an appliance
fault or breakdown:
Step 1: Always contact your installer or commissioning
engineer in the first instance, who must
thoroughly check all his work PRIOR to
requesting a service visit from Trianco.
Step 2: If your appliance has developed an in-guarantee
fault your installer should contact Trianco
Service Centre for assistance.
What happens if my installer/engineer is
unavailable?
Step 3: Contact Trianco Direct. We will provide you with
the name and telephone number of our
Service Agent. However, a charge may apply if
the fault is not covered by the appliance

Important Notice:
To comply with regulations in force, your new boiler must be installed and commissioned
by an OFTEC-registered engineer. The installation must also comply with current
Building Regulations, Part L.
Failure to meet the terms of these requirements may invalidate your guarantee.
THE PERSON(S) WHO INSTALLS THIS APPLIANCE, COMMISSIONS, SERVICES OR
CARRIES OUT ANY REMEDIAL WORK, IE ELECTRICAL FAULT FINDING, MUST
HAVE SUITABLE ENGINEERING QUALIFICATIONS
All servicing can be carried out from the front of the
boiler (50-90,000), thus allowing the boiler to be fitted
under a kitchen work top if required. The front mounted
flue-cover permits easy access for the removal of the
flue-baffles and cleaning of heating surfaces.
The boiler is fully automatic in operation and incorporates
all necessary safety controls to ensure safe and reliable
operation.
Trianco EuroStar boilers are supplied with the burner set
for Kerosene C2 to BS 2869 fuel to meet the Building
Regulation requirements for low level flue discharge. It is
recommended this fuel is also used when the boiler is
connected to a conventional chimney because of the
clean burning characteristics of Kerosene.
Balanced Flue Kits
The boilers are supplied suitably equipped for connection
to a conventional chimney, but can readily be converted
into a room-sealed balanced flue appliance by using a
Trianco balanced flue kit. These kits allow the boiler to be
installed in a wide variety of site conditions. (see bal-
anced flue kit details).
Note:
Only circular low level horizontal balanced flue kits
can be used on condensing boilers.
2. INTRODUCTION
Trianco boilers have been designed to conform to
European Directive/Standards BED 92/42 EEC LVD EN
60335-1 EMC 89/336/EEC.
The boiler design incorporates a secondary stainless
steel heat exchanger, which recovers heat from the flue
gasses that would normally be lost when using
conventional oil fired boilers.
The matched pressure jet burner which is exceptionally
quiet in operation, ensures clean and efficient
combustion with low NOxemissions
As the EuroStar balanced flue boiler is a truly room
sealed appliance, it is also eminently suitable for
installation in a garage.
The EuroStar boilers are suitable for all normal open
vented central heating and indirect hot water systems
and can also be used with sealed systems up to a
working pressure of 3 bar with the appropriate sealed
system safety equipment.
Two flow and return sockets are provided to facilitate
connection to the heating system.
To ensure the boiler is operating at its maximum efficiency,
the central heating return temperature should be 55°C or
less.
Maximum performance will be achieved by maintaining a
differential of 30°C between the flow and return temperatures.
Due to high efficiency of this range of boilers when running
in condensing and non-condensing mode, it is essential
that only a fully pumped system be used.

Clearance and Service Access
EuroStar 50/90
When siting the boiler, ensure adequate clearance is
allowed for making water and flue connections. As the
boiler can be fully serviced from the front, there is no
need for a headroom allowance nor provision for removal
of the kitchen work top but a clearance of at least 750mm
is required at the front of the boiler.
Hearth
The boiler must be fitted on a non-combustible base. Also
the floor must be level and capable of supporting the
installed weight of the boiler, including its water content.
Combustion and Ventilation Air
(Conventional flue boilers)
The provision of an adequate supply of combustion air is
essential for the efficient and safe operation of the boiler.
The air opening should be positioned so as to cause the
least possible draught to the occupants and located so it
is not liable to be accidentally blocked.
British Standard Code of Practice for Oil Firing BS 5410:
Part 1 requires a permanent air inlet opening of 550mm2
per kW of boiler rated output.
See Fig. 6 for air openings required for Trianco EuroStar
boilers.
4. INSTALLATION
Regulations
Installation of the boiler must comply with the following
British Standards and Regulations:
BS 5410: Part 1 - Code of Practice for Oil Firing.
BS 5449 - Forced Circulation Hot Water Central Heating
Systems.
The Building Regulations - Part ‘J’ (England and Wales)
Part ‘F’ Section 111(Scotland)
Part ‘L’
The Control of Pollution (Oil) Regulations
Current I.E.E. Regulations
Local Water Undertakings By-laws
OFTEC Installation Requirements for Oil Fired Boilers
and Oil Storage Tanks. OFST 100 and OFST 200.
Health and Safety at Work Act
The installer should be aware of his responsibilities under
the Act and provide, where necessary, appropriate
protection for persons carrying out the installation.
In the interest of safety, it is recommended that the
appliance is installed, commissioned and maintained by
an OFTEC registered technician.
A useful guide to ‘Safe Working Practices for Oil Firing
Technicians’ is published by OFTEC.
Electrical work should be carried out in accordance
with BS 7671:2001 by a qualified electrical engineer.
Siting the Boiler
Sound Levels
Whilst the low sound level of the Trianco EuroStar boiler
makes it eminently suitable for kitchen and utility room
installation, 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.
(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.
System Design
When operating your Trianco condensing boiler, the heating
system should be designed to the following parameters to
achieve the maximum system efficiencies.
For central heating systems using radiators

FIXING OF STRAIN
RELIEF BUSHES
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 - 50Hz electrical supply must be fused by a
double pole switch with a contact separation of at least
3mm in both poles, and shuttered socket (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(24x0,2mm) (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
supply cables).
All external cables entering the control box must be
secured in position by strain relief bushes supplied (see
diagram on how to secure cable).
Terminal connections are also provided in the control
panel for ancillary controls.
See wiring diagram Fig. 5.
Warning - High and Low Voltage
In certain parts of the country, where there is a known risk
of high or low voltage fluctuations, the oil burner shall be
prevented from starting by the use of a voltage sensitive
device if the voltage drops or increases sufficiently to
endanger the installation.
Thermostats
The boiler is fitted with a variable setting control
thermostat and a pre-set limit thermostat. Should the
boiler thermostat malfunction, the limit thermostat will
take over control and shut down the boiler.
Ventilation (Room sealed balanced flue boilers)
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. 7 for ventilation openings).
Extractor Fan (conventional flue only)
If the boiler room has an extractor fan, the combustion
performance of the appliance must not be affected when
the fan is running and all doors and windows are closed.
A flue gas check on the CO2% and smoke number should
be carried out to prove that combustion is satisfactory.
Heating and Domestic Hot Water Systems
The heating system should be installed in accordance
with current HVCA Codes of Practice and BS 5449 Part 1
‘Forced Circulation Hot Water Systems’.
Flow and return water connections can be made to the
boiler by using the tapings on the left or right hand side of
the boiler.
Fit drain-off cock in the lowest part of the system.
Where a boiler is also used for providing domestic hot
water, a double feed indirect cylinder to BS 1566 Part 1
must be used.
MAKE SURE ALL UNUSED BOILER TAPPINGS ARE
PLUGGED BEFORE FILLING THE SYSTEM.
Flush out the system to remove any swarf or residues
before fitting circulating pump.
Fig. 8

Condense Drain Connections
On the back edge of the condensing unit there are 2
screws, when they are removed they provided 2 cleaning
holes to allow the drain sockets to be cleaned.
The condense drainpipe can be fitted to either the left or
right hand side of the boiler.
To fit the drainpipe, remove the screws holding the back
casing in position and remove the back casing. Supplied
with the boiler is a set of plastic fittings, taking the two
straight connectors fit them on to the two drain connections
off the bottom of the condenser unit. Cut 3 pieces of plas-
tic pipe 175mm long, insert one into each of the straight
connectors, fit the tee fitting on to the end of the pipe
nearest to the side the drain will leave the boiler. On the
other pipe fit the elbow and connect the elbow and tee
together using the other piece of pipe. (165mm long)(Fig 4).
Using the remaining piece of pipe, pass it through the
side casing and connect to the tee fitting. From this point
it is the responsibility of the installer to fit the condensate
trap in a visible position and where no damage can be
caused to the appliance or surroundings if the trap was to
overflow. When installing the condensate trap, it is important
that the trap is filled with water, this provides a seal
against flue gas escape. The trap must be located internally
an an accessible position to allow maintenance to be
carried out. The trap should be checked at regular inter-
vals to ensure it is operating satisfactorily and serviced
annually. (Fig 9 and 10).
Plastic must be used for the drain with a minimum
dia of 15 mm, this can be run into a waste pipe or
external gully or soak away. Avoid external runs were
possible to reduce the risk of freezing
IMPORTANT
The drain pipe must be installed to allow the condensate
to drain naturally from the boiler with a min fall of 1:20.

5. OIL SUPPLY
Oil
The oil burner is factory set to burn Kerosene C2 to BS 2869.
Note: Only Kerosene is permitted for low level flue
discharge.
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 a
domestic oil tank, it does however need to be protected
from a fire that may originate in a nearby building,
therefore the tank should 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.
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 BS 799,
Pt. 5: 1987 and 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:
1 Where 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.
2 The cladding must extend 300mm beyond the tank.
3 The 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:
1 The tank is less than 10m from a stream.
2The tank is less than 50m from a well, spring, or drinking
water.
3 The tank cannot be viewed from the delivery point.
4 In 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
A long life flexible oil hose is supplied with the boiler, a
filter and shut-off valve are required. These should be
fitted as shown in Figs. 5 and 6.
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 outside
the building.
Fire Valve
A fire-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.
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. 11 )
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.

12
Two pipe oil supply (Fig. 12)
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 screw is fitted, on the BFP II pump remove the
end cover and filter, then remove the ‘U’ washer by
unscrewing the bottom screw, then replace the screw
ensuring it is fully inserted. An additional flexible hose is
also required.
A spring loaded non- return valve must be fitted in the
suction line to stop the oil running back to the tank.
A filter, 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. 13)
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. A
none-return valve is not required with this system but the
small horseshoe washer must be removed for a two pipe
system (see burner details).
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.

6. FLUE SYSTEMS
To evacuate the products of combustion safely and
thoroughly, the boiler must have an efficient flue system.
Under no circumstances should the boiler be installed
using an existing flue system.
All components used in the flue system should be suitable
for wet flues. The design and construction of the Trianco
balanced flue kits take these factors into account so the
following guidance notes are for conventional chimneys.
Reference should also be made to BS 5410 Part 1 if further
information is required on conventional chimneys.
Conventional chimney (Fig. 14)
Trianco condensing boilers operate at high efficiencies
with low flue gas temperatures. The flue system used on
this boiler must be suitable for low flue gas temperatures
and condensation.
1 The chimney should rise as vertically as possible and
terminate at a point not subject to down draughts or
wind effects.
2 The condensation produced in the flue system can be
allowed to run back in to the boiler. No separate drain
at the base of the flue system is required
3 Where an existing chimney is to be used it must be lined
with a stainless steel liner that is approved for use on
an oil fired condensing boiler. Note: Before fitting a flue
liner the chimney must be thoroughly cleaned free
from all traces of soot and scale.
4 If a rigid flue is to be fitted externally a twin wall flue
must be used. The flue must be constructed with a
stainless steel inner skin, insulation and incorporate
seals and be weather proofed.
5 The internal flue diameter must be 100 mm (4 in).
6 The flue pipe between the boiler and the chimney must
not be made from an moisture absorbent material.
Aluminum or plastic must not be used on any part of the
flue system.
7 The in-built flue gas resistance of the Eurostar is such
that it allows the boiler to operate reliably over the wide
range of chimney draughts encountered from typical
domestic chimneys. Under normal draught conditions,
the flue should terminate with a standard cowl.
IMPORTANT
Ensure that all the joints on the flue system are sealed
and that no condense can escape.
15
FIG.14

INSTALLATION NOTES
(a) Location (Fig. 15)
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.
A distance of at least 600mm must be allowed
between the terminal and any window, door or
other opening into the building, (see diagram for
recommended terminal positions).
(b) Flue Sealing
As the flue system operates under positive
pressure, it is essential to ensure that all flue
joints are made.
(c) Fuel
Only Kerosene C2 to BS 2869 is permitted for
boilers using low level flue discharge.
(d) Important
Trianco Flue Kits have been designed primarily
to use with Trianco boilers and as such
compatibility with other makes of boiler cannot
be guaranteed.
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.
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.
16
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) Care should be taken when positioning the flue to
take into account the plume of condensed flue
gasses produced to ensure they do not cause a
nuisance.

IMPORTANT: TO AID ASSEMBLY, IT IS NECESSARY
TO APPLY A THIN BEAD OF LUBRICANT (E.G.
WASHING - UP LIQUID OR VASELINE) TO ALL FLUE
JOINTS THAT INCORPORATE ‘O’- RING SEALS.
AS THE FLUE SYSTEM OPERATES UNDER
POSITIVE PRESSURE, ALL FLUE JOINTS THAT DO
NOT INCORPORATE ‘O’- RING SEALS SHOULD BE
SEALED WITH SILICONE SEALANT.
THE BOILER PRODUCES CONDENSATE DURING
NORMAL RUNNING, IT IS IMPORTANT TO ENSURE
ALL SEALS ARE MADE AND CORRECT GASKETS
USED.
TO ENSURE ANY CONDENSE PRODUCED IN THE
FLUE DRAINS AWAY INCLINE THE FLUE SLIGHTLY
FROM THE BOILER
TERMINAL GUARDS (Fig. 16)
When the terminal is positioned where there is the
possibility of accidental contact by persons, or of
damage to the terminal, an approved guard is necessary.
Generally, exhaust 2 metres above ground level
alleviates the necessity for a guard.
Asuitable guard is available from Trianco, Part No
204123.

ASSEMBLY METHOD
1. Having decided the position of the boiler, accurately
mark out the position of the terminal and cut a hole
130mm diameter through the wall. (See Figs. 17/18
and 19).
2. Unpack the boiler.
3. Lift off the top panel.
4. Remove the four nuts securing the flue socket in
place.
5. Take flue socket plate off top of boiler leaving the flue
gasket in position.
6. If the flue is to be fitted terminating to the left or right
hand side of the boiler, the corresponding section of
side casing must be removed.
7. To remove the section of side casing, cut through the
retaining tabs.
8. Fit sealing plate over four studs leaving the flue gasket
in position and place terminal gasket on top of sealing
plate. Both these gaskets are supplied with boiler.
9. Position the boiler.
10. Unpack the Terminal Kit and identify all components.
11. Check to see that the O-ring is in location groove on
the inner flue pipe of elbow duct assembly. Applying
a small amount of lubricant i.e. vaseline to O-ring will
aid assembly.
12. Assemble kit together by sliding flue terminal inside
terminal elbow duct assembly.
13. Slide completed assembly through the wall from inside.
14. Move boiler in position and holding up terminal mounting
flange, slide terminal back between fixing studs on
boiler.
15. Slide terminal mounting plate down over studs and
secure using the four nuts previously removed.
16. Adjust terminal length to give a minimum distance of
140mm from end of terminal to wall.
17. Connect hose from burner to socket on end of terminal
using clip provided.
18. Make good the inside and outside wall around the flue
(ie cement or suitable filler).
19. Replace top panel.
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.
