1 General Information
Alternatively connection can be made through an unswitched
shuttered socket and 3A fused 3 pin plug both to the current
issue of BS1363 may be used, provided they are not used in a
room containing a bath or shower.
The mains supply cable and other cables connected to the
boiler must be the PVC flexible type of at least 0.75mm
2
(24/
0.20mm).
The colours of three core flexible cable are, blue - neutral, brown
- live, green and yellow - earth.
The wire coloured blue must be connected to the terminal
marked ‘N’ or ‘Black’.
The wire coloured brown must be connected to the terminal
marked ‘L’ or ‘Red’.
The wire coloured green and yellow must be connected to the
terminal marked ‘E’ or ‘Green’ or the earth symbol.
1.6 Condensation Drain
A plastic drain pipe must be fitted to allow discharge of
condensate to a drain.
Condensate should, if possible, be discharged into the internal
household draining system. If this is not practical, discharge
can be made externally into the household drainage system or
a purpose designed soak away, see section 9.2 for more
details.
1.7 Heating System Controls
All heating system controls must be low voltage or potential
free.
It is recommended that a programmer and room thermostat
control the boiler.
Thermostatic radiator valves may be installed, however they
must not be fitted in a room where the room thermostat is
located.
Note: For further information, see the current issue of the
Building Regulations, approved document L1, and the
references:
1) GIL 59, 2000: Central heating system specification (CheSS)
and
2) GPG 302, 2001: Controls for domestic central heating
system and hot water. BRECSU.
1.8 Vertical Plumbing Kits
Where the heating flow and return pipes come from above the
boiler, vertical plumbing kits are available to facilitate this.
Contact Hepworth Heating for further details.
Do not route any pipes behind the boiler, unless a vertical
plumbing kit is used.
