ELECTRICAL SUPPLY
The appliance is supplied for operation on 230V
@ 50Hz electrical supply, it must be protected
with a 3-amp fuse. The method of connection to
the mains electricity supply must allow for
complete isolation from the supply. The preferred
method is by using a double-pole switch with a
contact separation of at least 3mm. The switch
must only supply the appliance and its
corresponding controls, i.e. time clock, room ther-
mostat, etc. Alternatively an un-switched shuttered
socket with a fused 3-pin plug both complying
with BS 1363 is acceptable.
3.8
MOUNTING ON A COMBUSTIBLE SURFACE
If the appliance is to be fitted on a wall of combus-
tible material, a sheet of fireproof material must
protect the wall.
3.9
TIMBER FRAMED BUILDINGS
If the appliance is to be fitted in a timber framed
building, it should be fitted in accordance with the
Institute of Gas Engineers publication (IGE/UP/7)
“Guide for Gas Installations in Timber Frame Buildings”.
3.10
CONDENSATE DISPOSAL
When choosing a location for the boiler,
consideration should be given to the disposal of
the condensate discharge into a suitable drain or
soil pipe. The condensate outlet pipe must be
connected to the drain in accordance with building
regulations or other rules in force.
3.11
INHIBITORS
The system shall be flushed in accordance with
BS 7593. If an inhibitor is to be used, it shall be
from a reputable manufacturer and shall be
administered in strict accordance with the
manufacturers instructions.
litres of expansion from within the system, generally
this is sufficient, however if the system has an
unusually high water content, it may be necessary
to provide additional expansion capacity (see 6.19).
3.6.6
FILLING POINT
A method for initial filling of the system and
replacing water lost during servicing etc. must be
provided. This method of filling must comply with
the local water authority regulations. Fig. 5 shows
a widely accepted method.
3.6.7
LOW PRESSURE SEALED SYSTEM
An alternative method of filling the system would be
from an independent make-up vessel or tank
mounted in a position at least 1 metre above the
highest point in the system and at least 5 metres
above the boiler (see fig. 5 A). The cold feed from
the make-up vessel or tank must be fitted with an
approved non-return valve and stopcock for isola-
tion purposes. The feed pipe should be connected
to the return pipe as close to the boiler as possible.
3.6.8
FREQUENT FILLING
Frequent filling or venting of the system may be
indicative of a leak. Care should be taken during
the installation of the appliance to ensure all
aspects of the system are capable of withstand-
ing pressures up to at least 3 bar.
