4. INSTALLATION
REGULATIONS
Installation of the boiler must comply with the following
British Standards and Regulations:
BS 5410: Part 1 – Code of Practise for Oil-Firing.
BS 5449 – Forced Circulation Hot Water Central Heating
Systems.
Building Regulations - Part J (England and Wales)
- Part F sect. 111 (Scotland)
- Part L
The Control of Pollution (Oil) Regulations
Current I.E.E. Regulations
Local Water Undertakings Bylaws
OFTEC Installation Requirements for Oil-Fired Boilers and
Oil Storage Tanks, OFST 100 & 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 all persons carrying out the installation.
In the interests of safety, it is required that the appliance is
installed, commissioned and serviced by and OFTEC
registered technician.
A guide to safe working practices for oil-firing technicians is
available from 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 boiler makes it suitable for
utility room installation, the following factors should be taken
into consideration before installation:
(a) Some people are particularly sensitive to low noise
levels – discuss with the householder.
(b) Low-level flue terminals produce some exhaust noise,
so care should be taken when siting adjacent to
neighbouring property, patios and play areas.
(c) Due to the condensing nature of the boiler, a plume of
water vapour will be discharged from the flue. This
should be taken into account when siting the flue
terminal. Refer to section on flue systems.
Clearance and Service Access
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 headroom allowance.
However, a clearance of at least 750mm is required at the front
of the boiler for future service access.
Hearth
The boiler must be fitted on a non-combustible base, which is
level and capable of supporting the installed weight of the boiler,
including its full water content. The base should be above ground
level to prevent water damage.
SYSTEM DESIGN
To achieve the maximum system efficiencies, the heating system
should be designed to the following parameters:
Boiler Flow Temperature - 50°C to 80°C
Flow Differential Temperature - 10°C to 30°C
COMBUSTION AND VENTILATION AIR
The provision of an adequate supply of combustion air is
essential for the efficient and safe operation of the boiler. The
combustion air inlet is located at the top of the front door of the
appliance. Under no circumstances should this be covered or
blocked.
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 Central Heating Systems.
The flow water connections can be made to the boiler by using
the tappings on the left or right hand side of the boiler. The return
is made via the connection on the secondary heat exchanger.
All exposed pipework connecting the boiler to the heating system
must be lagged.
A drain-off cock should be fitted in the lowest part of the system.
Where the boiler is also used for providing domestic hot water, a
double-feed indirect cylinder to BS 1566 Part 1 must be used.
Flush out the system to remove any residue before fitting the
circulating pump.
Make sure all unused boiler tappings are plugged before
filling the system.
