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 ‘G’ & ‘J’ (England and Wales)
Part ‘F’ Section 111 (Scotland)
Part ‘L’
BS 7671
Local Water Undertakings By-laws
OFTEC Installation Requirements for Oil Fired Boilers and
Oil Storage Tanks.
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, the boiler should be installed and
commissioned by a competent engineer, preferably
OFTEC trained and registered.
A useful guide to ‘Safe Working Practices for Oil Firing
Technicians’ is published by OFTEC.
The installer of the boiler must be registered as competent
UDHWSS installer.
ELECTRICAL WORK SHOULD BE CARRIED OUT BY A
QUALIFIED ELECTRICAL ENGINEER
Siting the Boiler
Sound Levels
Whilst the low sound level of the Trianco EuroStar Combi
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 sometimes
transmit noise.
(d) Low level flue terminals produce some exhaust noise,
so care should be taken when siting adjacent to a
neighbouring property.
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, but if fitted below a
worktop this must be made removable for the provision of
fitting replacement parts in the future.
Hearth
The boiler
MUST
be fitted on a suitable non-combustible
base.
WATER SYSTEMS
Heating
The installation must comply with the requirements of BS
6798 and BS 5499. Maximum water temperature is 86 C.
The appliance is supplied with 2 stop valves (flow and
return) terminating in compression connections (22mm).
The appliance also incorporates the following
components:-
Pump
On the return to the boiler
Expansion Vessel
10 litres, pre-charged to 0.5 bar
Pressure Relief Valve
Set to operate at 3 bar
A system schematic is given in Fig. 4 & 5.
Drain Cock
Drain cock(s) should be fitted at the lowest point in the
system to enable the water to be drained. A drain cock is
fitted to the front lower section of the storage tank.
Expansion Vessel Requirements
The boiler is supplied with a 10 litre expansion vessel,
capable of accepting the 82 litre stored water expansion at
a cold fill of up to 1 bar.
An additional expansion vessel must be fitted if a system
water volume exceeds 42 litres not including boiler or if the
initial system pressure is above 0.75 bar.
For systems having a larger capacity, multiply the total
water content (boiler and system) by the factor to obtain
vessel size in litres.

EXAMPLE
A system to be filled to 1 bar cold fill (vessel to be charged
1 bar) has 82 litres of stored water and 60 litres of water in
the central heating system, requires a total expansion vessel
of:
82 + 60 = 142 litres
Multiply by factor 0.11 (from chart)
= 15.62 litres = Total expansion volume
Expansion vessel supplied = 10 litres
We therefore need 15.62 - 10 litres = 5.62 of extra expansion.
An additional vessel of at least 5.62 litres would therefore
be required to be fitted.
Note: if the appliance pressure gauge indicates a rise of
pressure to 2.6 bar or higher with the radiator circuit oper-
ating at full output of the boiler, an additional expansion
vessel will be required in the system.
