1.5 Gas Supply
The gas installation shall be in accordance with the current
issue of BS6891.
The supply from the governed meter must be of adequate size
to provide a steady inlet working pressure of 20mbar (8in wg) at
the boiler.
On completion test the gas installation for soundness using the
pressure drop method and suitable leak detection fluid, purge
in accordance with the above standard.
1.6 Electrical Supply
WARNING. This boiler must be earthed.
All system components shall be of an approved type and shall
be connected in accordance with the current issue of BS7671
and any applicable local regulations.
Connection of the boiler and system controls to the mains
supply must be through a common isolator and must be fused
3A, maximum. This method of connection must be by a fused
double pole isolating switch, with a minimum contact separation
of 3mm on both poles. The switch should be readily accessible
and preferably adjacent to the appliance. It should supply the
appliance only and be easily identifiable as so doing.
Alternatively, an unswitched shuttered socket outlet and 3A
fused 3 pin plug, both to the current issue of BS1363 may be
used provided that they are not used in a room containing a bath
or shower.
Wiring to the boiler must be to the current issue of BS6500 Table
16, not less than 0.75mm
2
(24/0.20mm).
1.7 Contents of Packaging
The boiler is delivered in one pack, refer to Section 4.1 for
contents.
1.8 Water System
This boiler may be fitted to an open vented or a sealed water
system.
1.9 Drain
System
A drain tap must be provided at the lowest points of the system
which will allow the entire system, boiler and hot water cylinder
to be drained.
Draining taps should be to the current issue of BS2879.
Boiler
A draining point is fitted at the bottom right hand side of the heat
exchanger.
Cover the controls to avoid water damage.
If required remove the combustion chamber front cover to
improve access.
1.10 Safety Valve
A safety valve need not be fitted to an open vented system.
1.11 Location
This boiler is not suitable for outdoor installation.
This 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 a boiler in a room
containing a bath or shower. Any electrical switch or boiler
control utilising mains electricity should be placed so that it
cannot be touched by a person using the bath or shower. The
electrical provisions of the Building Standards (Scotland) apply
to such installations in Scotland.
The boiler must be mounted on a flat wall which is sufficiently
robust to take its total weight.
The boiler may be fitted to a wall made of combustible material.
