Insulation Pads / Ceramic Fibre
These can cause irritation to skin, eyes and the
respiratory tract.
If you have a history of skin complaint you may
be susceptible to irritation. High dust levels are
usual only if the material is broken.
Normal handling should not cause discomfort, but
follow normal good hygiene and wash your hands
before eating, drinking or going to the lavatory.
If you do suffer irritation to the eyes or severe
irritation to the skin seek medical attention.
Electrical Supply
The boiler must be earthed.
All system components shall be of an approved
type and all wiring to current I.E.E. wiring
regulations.
External wiring must be correctly earthed, polarised
and in accordance with the relevant standards.
In GB this is BS 6891.
In IE this is the current edition of I.S.813 "Domestic
Gas Installations".
The boiler must be connected to a permanent
230V ac, 50Hz supply.
Connection of the whole electrical system of
the boiler, including any heating controls, to the
electrical supply must be through one common
isolator and must be fused 3 Amp maximum.
Isolation should be by a double pole switched
fused spur box, with a minimum gap of 3mm
for both poles. The fused spur box should be
readily accessible and preferably adjacent to the
appliance. It should be identified as to its use.
Alternatively connection can be made through an
unswitched shuttered socket and 3A fused 3-pin
plug both to the current issue of BS 1363 may
be used, provided they are not used in a room
containing a bath or shower.
The colours of three core flexible cable are,
- live, green and yellow
blue - neutral, brown
- earth.
General Note
This boiler is designed to provide central heating
from a fully pumped open-vented or sealed water
system with a fully indirect cylinder.
Once the controls are set the boiler operates
automatically.
Please read these instructions and follow them
carefully for the correct installation and economical
use of your boiler.
Water Treatment
In the case of an existing installation, it
ESSENTIAL that prior to installing the new boiler
the system is thoroughly flushed. For optimum
performance after installation of a new system,
the boiler and its associated central heating
system should also be flushed. Flushing should
be carried out in accordance with BS7593: 1992
using a cleanser such as Sentinel X300 or X400,
Fernox Superfloc or Salamander corrosion guard
cleaner.
For long-term corrosion protection, after flushing,
an inhibitor suitable for stainless steel exchangers
should be used, refer to the current issue of BS
5449 and BS 7593 on the use of inhibitors in central
heating systems. Examples are Sentinel X100
Fernox or Salamander corrosion guard inhibitor.
Compartment or Cupboard Installations
If the boiler is fitted into a compartment or cupboard
it does not require ventilation openings.
Do not use the compartment or cupboard for
storage.
Clearances
If fixtures are positioned close to the boiler, space
must be left as shown in diagram 2.1. Enough
space must also be left in front of the boiler to
allow for servicing.
