3. TECHNICAL SPECIFICATION
exhaust noise, so care should be taken
when siting adjacent to neighbouring
property.
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.
Unpacking the Boiler
(a) Cut through straps and remove
carton
(b) Remove the front door, remove
pack of parts, lift outer casing from
boiler and move to a safe place to
avoid damaging.
(c) Remove securing screws fixing boiler
to pallet.
(d) The boiler can now be removed
from pallet
In the interest of safety, the boiler should be
commissioned by an OFTEC trained and
registered engineer.
A useful guide to ‘Safe Working Practices for
Oil Firing Technicians’ is published by
OFTEC.
ELECTRICAL WORK SHOULD BE CARRIED
OUT BY A QUALIFIED ELECTRICAL
ENGINEER
Siting the Boiler
Sound Levels
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 BF terminals produce some
