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.
LIFTING
The appliance will require two people to lift into position, or
specialised lifting equipment. Do not mount the boiler on the
wall unless all necessary precautions have been made.
Electrical work should be carried out in accordance with BS
7671:2001 by a qualified electrical engineer.
SITING THE BOILER
Sound Levels
Despite the low sound levels of the boiler, 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) Small rooms tend to amplify noise, particularly if the wall
construction is hollow or the surface tiled.
(c) A chimney passing through a bedroom will sometimes
transmit noise.
(d) Low-level flue terminals produce some exhaust noise, so
care should be taken when siting adjacent to neighbouring
property, patios and play areas. Refer to flue details (
page
18 onwards).
(e) 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. Routine servicing can
be carried out from the front. See
page 8 for clearance
dimensions.
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 - 20°C to 30°C
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.
Maximum water temperature is 80°C.
The flow and return connections are made via 22mm
compression fittings at the top-right of the boiler, and can be
run through either the rear or the top.
Where the boiler is also used for providing domestic hot water,
a double-feed indirect cylinder to BS 1566 Part 1 must be
used.
A drain-off cock is fitted to the underside of the boiler.
However, one should always be fitted to the lowest point on the
heating circuit.
Flush out the system to remove any residue before filling the
system.
