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 550mm
2
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
Boiler flow temp
70°C to 90°C
Boiler return temp
50°C to 70°C
Flow differential temp
10°C to 30°C
