4.5 Electrical Supply

The boiler must be earthed.
All system components shall be of an approved type and
all wiring to current I.E.E. wiring regulations.
External wiring must be correctly earthed, polarised and
in accordance with the relevant standards.
In GB this is BS 7671.
In IE this is the current edition of I.S.813 "Domestic Gas
Installations".
The boiler must be connected to a permanent 230V ac,
50Hz supply.
Connection of the whole electrical system of the boiler,
including any heating controls, to the electrical supply
must be through one common isolator and must be fused
3 Amp maximum.
Isolation should be by a double pole switched fused
spur box, with a minimum gap of 3mm for both poles.
The fused spur box should be readily accessible and
preferably adjacent to the appliance. It should be
identified as to its use.
Alternatively connection can be made through an
unswitched shuttered socket and 3A fused 3-pin plug
both to the current issue of BS 1363 may be used,
provided they are not used in a room containing a bath
or shower.

neutral, brown - live, green and yellow - earth.

4.6 Condensate 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 10.3 for more details.

4.7 Heating System Controls

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:
All systems must have at least one radiator not
fitted with a thermostatic valve.
NOTE:
For further information, see the current issue of
the Building Regulations, approved document
