ARNING – The addition of anything that may interfere with
the normal operation of the appliance without the express
written permission of Trianco Ltd could invalidate the
appliance warranty and infringe the Gas Safety
(Installation and Use) Regulations.
Incorrect installation may cause harm to people, animals and pro-
perty. The manufacturer is not liable for damage caused by
incorrect installation and by non-observance of the instructions
accompanying the boiler
Installation, maintenance and any other operation must be carried
out in compliance of current regulations and instructions supplied
by the manufacturer.
Installation is the purchaser's responsibility.
The boiler is supplied in a carton pack; when it is removed, ensure
that the appliance is complete and that all the parts are supplied.
The packing components (clips, plastic bags, polystyrene foam,
etc) must be kept out of reach of children, since they are a hazard
for them.
The technical notes and instructions contained in this document
are to help fitters install the system correctly.
Any repair should be carried out using solely original spares and
operations involving the removal of the appliance must only be carried out by qualified engineers. Failure to abide by the above
exempts the manufacturer from any liability and may jeopardise the
the safety of the unit.
It is forbidden to climb on to the unit.
INSTALLATION AND INITIAL START-UP OF THE BOILER MUST
BE CARRIED OUT BY QUALIFIED PERSONNEL, IN ACCORDANCE WITH CURRENT NATIONAL REGULATIONS ON
INSTALLATION AND ANY DIRECTIONS FROM LOCAL AUTHORITIES AND PUBLIC HEALTH BODIES.
When turning the boiler on or off, the fan may make a slightly louder noise because of the rapid increase or reduction in the number
of rotations.
The expansions of the materials that make up the unit, due to rises
or falls in temperature, may cause slight tapping noises. This may
normally occur after the boiler is turned off or on.
An excessively high flow-rate of domestic hot water may cause a
slight noise in the circuit and a drop in temperature at the domestic
water outlet.

1.1 USE OF ANTIFREEZE LIQUID
1.2 FEATURES OF UNDER FLOOR
HEATING SYSTEMS
● If you smell gas:
- do not operate electrical appliances
- extinguish any fires
- close the stopcock upstream of the meter
- open the windows and ventilate the room
- call your local authorised engineer
● Do not store or use flammable materials near the boiler.
● Do not obstruct intake/exhaust terminals.
● To guarantee boiler efficiency and correct operation, it is
imperative to have yearly maintenance, and combustion
analysis every two years, carried out by qualified
engineers, and to have the system booklet prepared, as
stipulated by law.
● It is forbidden to touch the boiler either with bare feet
and/or with wet parts of the body.
● In order to clean the outside parts, turn off the boiler turn
off the power at the isolating switch. Clean with a damp
cloth. Do not use detergents and/or harsh liquids, or toxic
products.
● In order to carry out any work on the boiler, do not mount
it on chairs, stools, ladders or unstable stands.
● Before carrying out any work on the boiler always turn
the power off at the isolating switch
● The user is forbidden to carry out any maintenance work
on the boiler that must be carried out by a specialised
engineer.

1.3 SAFETY ADVICE
In floor systems, the use of plastic pipes without
protection against penetration of oxygen through
the walls can cause corrosion of the system's
metal parts (metal piping, boiler, etc), the formation of oxides and bacterial agents.
To prevent this problem, it is necessary to use pipes with an
"oxygen-proof barrier", in accordance with standards DIN
4726/4729.
If pipes of this kind are not used, keep the system separate by installing heat exchangers or those with a specific
system water treatment.
In floor systems, a system safety thermostat must
be installed to protect against overtemperature
calibrated at around 45°C (see wiring diagram on
page 14).
TRIANCO is not liable for damage caused to the unit or the
system due to failure to comply with the above.
If antifreeze substances are used in the
system, check carefully that they are compatible with the aluminium that forms the body of
the boiler.
In particular, DO NOT USE ordinary ETHYLENE
GLYCOL, since it is corrosive in relation to aluminium
and its alloys, as well being toxic.
Trianco suggests the use of suitable antifreeze products
and in the correct dose, which will prevent rust and
incrustation taking place.
Periodically check the pH of the water-antifreeze mixture of the boiler circuit and replace it when the amount
measured is lower than the limit stipulated by the manufacturer.
DO NOT MIX DIFFERENT TYPES OF ANTIFREEZE
TRIANCO is not liable for damage caused to the boiler
or system as a result of the use of incorrect antifreeze or
additive substances.
pag. 5
The TriStar OPTIMA boiler is a sealed-type electronic
condensing gas wall mounted boiler with high seasonal
efficiency.
The burner, of premix type, guarantees high efficiencies
and safe combustion at all power ratings, with minimal
pollutant emissions.
The electronic board provides for a periodic selfdiagnostic of the functions, with indications of any irregularities
or failures by means of a code that appears on the control panel display.
It is simple to use and has fully automatic operation, and
thus user operations are reduced to the basic simple
operations.
The production of domestic hot water is always activated and has priority over the heating function.
The external temperature probe (OPTIMAZER) must be
fitted to ensure maximum running efficency.
The boiler is started and regulated automatically so as
to meet the requirement of the heating system.
With the outside temperature probe, the system’s water
temperature is regulated automatically according to the
heating curve set, guaranteeing maximum comfort in all
conditions.
DOMESTIC HOT WATER DRAW OFF (CB MOD.)
When calling for domestic hot water, the boiler, by
means of an appropriate sensor, automatically switches
over in order to guarantee supply of the correct amount
of water at the desired temperature.
Regulation of the domestic water temperature is also
carried out precisely and automatically by the boiler’s
electronics.
The domestic hot water comfort function is activated
automatically at the end of every withdrawal and guarantees a quick response for subsequent withdrawals
for the programmed time.
2 GENERAL FEATURES
2.1 WINTER OPERATION
The boiler is started and regulated automatically so as
to meet the domestic water requirement.
Switching from summer to winter operation and viceversa may be carried out by hand or automatically (if external probe present) depending on the outside temperature set.
2.2
SUMMER OPERATION (CB MODELS)
If the boiler is to be installed in a area recognised for
having hard water, it is recommended that a suitable
water treatment device is installed in the mains supply
to the boiler.
The water hardness can be determined by using the
standard test paper or by contacting your local water
authority.

Caution: the pressure relief valve is set at 3 bar therefore all
pipework, fittings, etc. should be suitable for pressures in
excess of 3 bar.
The pressure relief discharge pipe should be not less than
15mm dia, run continuously downward and preferably over a
drain. It should be routed in such a manner that no hazard
occurs to occupants or causes damage to wiring or electrical
components. The end of the pipe should terminate facing
down and towards the wall.
The discharge must not be above a window, entrance or other
public access. Consideration must be given to the possibility
that boiling water / steam could discharge from the pipe.
For hydraulic connection of the boiler, use the equipment kit
and follow the directions given on the attached instruction
sheet.
The 10 Ltr expansion vessel supplied with the boiler is suitable for a system volume of approx. 140 Ltr.
An additional vessel will be required for system volumes
above this, following this formula:
V= 0,07 x C
V = Expansion vessel volume (Ltr)
C = Water system volume (Ltr)

The following guidelines indicate the general require-
ments for siting balanced flue terminals.
Recommendations for flues are given in BS 5440
Pt.1.
If the terminal discharges onto a pathway or passage-
way, check that combustion products will not cause
a nuisance and that the terminal will not obstruct
the passageway.
If a terminal is less than 2 metres above a balcony,
above ground or above a flat roof to which people
have access, then a suitable terminal guard must
be provided.

Important: since the TRISTAR OPTIMA is a condensing boiler, exhaust temperature is very low; therefore
it is normal for part of the residual water vapour in the
exhaust fumes to be capable of condensing in the flue
pipe
You are advised to pay attention to the following:
a - to the positioning of the exhaust terminals (they
may drip and also produce a ploom of condensation)
b - to the incline of the flue pipe so as to avoid con-
densation becoming stagnant;
c - to the correct positioning of the condensation col-
lection parts;
d - to connecting the condensation drain correctly.
The TRISTAR OPTIMA boiler is a type C certified
Appliance (sealed boiler).
Connection of the flue exhaust pipes is made according to the diagrams attached.
For the parts to use, please refer to the TRIANCO
catalogue of boiler installation accessories.
IMPORTANT: As with all flues the kit must be installed

IMPORTANT: As with all flues the kit must be installed taking
due account of the current issue of BS 5440 parts 1 & 2 and timber frame housing REF IGE/UP/7/1998.
Also note that the requirements will vary depending upon the kit
being installed. Guidance is provided but unless otherwise stated, always comply with the recommendations of the relevant
codes of practice.
EXPOSED PIPE: any pipe exposed to the elements should be
protected with a suitable material, and maintained regularly.
Installing the Balanced Flue Kit
1 Having decided the position of the boiler, accurately mark
out the position of the terminal and boiler fixing holes using
the template provided. Cut a ø120mm hole through the wall
to accept the terminal, and drill 2 ø8mm holes to accept
rawlplugs and mounting bolts.
2 Fix the boiler to the wall using the wall-mounting bracket.
3 Pass the terminal through the wall, and fit the internal wall
seal to the terminal.
4 Fit the ø60mm (black) seal to the inner spigot on the boiler
flue off-take (Fig. 1).
5 Fit the ø100mm and Ø60mm (blue) seal into the 90° con-
centric bend.
6 Fit the 90° concentric bend into the boiler flue off-take, and
secure in position with clamp.
7 Slide the terminal into the 90° bend ensuring it is pushed
home firmly, and ensure wall seal is fitted against wall.
8 Fit the external wall seal to the terminal.
9 To extend the terminal length, use the 500mm concentric
pipe and cut to length, ensuring the inner is cut 20mm longer than the outer.
NOTE: For High Level Balanced flue Kit
1 Measure vertically 950mm (max) from position of the cut-
out on the template to give position of terminal required.
2 Cut the 1000mm concentric pipe to required length. Fit the
ø100mm and ø60mm (blue) seal into the pipe.
3 Fit the concentric pipe into the boiler flue off-take, and secu-
re in position with clamp.
4 Fit 90° concentric bend into pipe, and fit remaining compo-
nents as above.
IMPORTANT:
When installing the flue system, it is important that the flue
assembly inclines slightly up from the boiler. This will allow
any condensation formed to run back to the condense drain
