1.5 B.S.I. Certification
This boiler is certificated by B.S.I. for safety and performance.
It is, therefore, important that no alteration is made to the boiler,
without permission, in writing, from Hepworth Heating Ltd.
Any alteration not approved by Hepworth Heating, could
invalidate the B.S.I. certification, boiler warranty and could also
infringe the statutory requirements.
1.6 Gas Supply
The gas installation shall be in accordance with the current
issue of BS6891.
The supply from the governor meter must be of adequate size
to provide a steady inlet working pressure of 20mbar (8in wg) at
the boiler.
1.7 Electrical
WARNING. This boiler must be earthed.
The electrical installation must be carried out by a competent
electrician. All external components shall be of the approved
type and shall be connected in accordance with the current
issue of BS7671 and any local regulations which apply.
Connection of the boiler and any system controls to the mains
supply through an unswitched shuttered socket outlet and 3A
fused 3 pin BS1363 plug. Alternatively, a 3A fused double pole
isolating switch may be used, having a minimum double pole
contact separation of 3mm, serving the boiler and system
controls only.
Heat resistant flexible cable of at least 0.75mm 2 (24/0.20mm)
to BS6500 Table 16, must be used for all connections within the
boiler casing.
1.8 Boiler Location
This boiler is not suitable for outside installation.
The boiler may be installed in any room, although particular
attention is drawn to the requirements of the current issue of
BS7671 with respect to the installation of the boiler in a room
containing a bath or shower. Any electrical switch or boiler
control utilising mains electricity should be so situated that it
cannot be touched by a person using the bath or shower. The
electrical provisions of the Building Standards (Scotland)
Regulations are applicable to such installations in Scotland.
The boiler must stand on a level floor, conforming with the local
authority requirements and building regulations. The base
temperature is within the requirements of BS5258. The boiler
may be stood on a wooden floor but a metal base plate is
required to protect plastic tiles and similar floor coverings.
Suitable clearance needs to be available at the sides of the
boiler to facilitate direct connection of pipework and making
good around the flue assembly. The actual clearance required
will vary with site conditions.
The casing can be fitted to the boiler at various heights. The top
casing can be discarded, if preferred, when fitting the boiler
under a worktop or fixture, see diagram 1.2.
When the boiler is to be installed level with work surfaces etc.,
minimum clearances should be provided as shown in diagram
1.3. Work tops which overhang the cupboard sides almost in
contact with the casing top, require a larger minimum air gap.
Flush sided fixtures require the same overall minimum space
but can have a reduced air gap on one side.
Boilers to be installed under work tops or fixtures, with or without
the casing top fitted, should be positioned to provide minimum
clearances as shown in diagram 1.4.
