INSTALLATION
37 WATER CONNECTIONS
1. Remove the plastic plugs from the flow and
return pipes.
2. Make all water connections and check for
water soundness.
38 ELECTRICAL CONNECTIONS
WARNING. The appliance must be efficiently earthed.
A mains supply of 230 V ~ 50 Hz is required.
All external controls and wiring must be suitable for mains voltage.
Wiring should be in 3-core PVC insulated & sheathed cable, not
less than 0.75mm
2
(24 x 0.2mm) to BS. 6500 Table 16 Wiring
Regulations and local regulations. For IE reference should be
made to the current ETCI rules for electrical installations.
Connection must be made in a way that allows complete isolation
of the electrical supply - such as a double pole switch, having a
3mm (1/8") contact separation in both poles or a plug and socket,
serving only the boiler and system controls. The means of isolation
must be accessible to the user after installation.
36 GAS CONNECTION
39 EXTERNAL CONTROLS
External wiring must be in accordance with the current I.E.E.
(BS 7671) Wiring Regulations. For Ireland reference should
be made to the current ETCI rules for electrical installations.
The wiring diagrams illustrated in Frames 41-43 cover the
systems most likely to be fitted to this appliance.
For wiring external controls to the Classic FF boiler,
reference should be made to the system wiring diagrams
supplied by the relevant manufacturer, in conjunction with
the wiring diagrams shown in Frames 41-43.
Difficulty in wiring should not arise, providing the following
directions are observed:
1. Controls that switch the system on or off, e.g. a time
switch, must be wired, in series, in the live mains lead to
the boiler.
2. Controls that override an on/off control, e.g. frost
thermostat, must be wired into the mains lead, in parallel,
with the control(s) to be overridden. Refer to Frame 43.
3. If a proprietary system is used, follow the instructions
supplied by the manufacturer.
4. System designs featuring controls or wiring
arrangements which allow the boiler to fire when there is
no pump circulation taking place should not be fitted.
Advice on required modifications to the wiring may be
obtained from the component manufacturers.
Notes.
1.
Connection between a frost thermostat and the time
control should be made without disturbing other wiring.
2.
A frost thermostat should be sited in a cool place in the
house, but where it can sense heat from the system.
Refer to 'Gas Supply ', page 7.
Refer to Frame 2 for gas inlet service dimensions.
A minimum pressure of 20 mbar MUST be available at the boiler inlet
with the boiler operating. The main gas cock is on the left hand side of
the gas control valve, as shown. To facilitate connection the gas cock
may be removed from the gas control valve.
