b) connecting into the internal discharge branch (e.g.
sink waste) with an external termination, the
condensate draining pipe should have a minimum
diameter of 22 mm with no length restriction and
should incorporate a siphon with a 75 mm (
3 ) (built
into the boiler) seal. The connection should preferably
be made down stream of the sink waste siphon. If the
connection is only possible upstream, then an air
break is needed between the two siphons. This is
normally provided by the sink waste.
c) terminating in a gully ( 4 ) below grid level ( 5 ) and
above the water level. The external pipe length should
be kept as short as possible to minimise the risk of
freezing and should not be more than 3 m.
d) at a condensate absorption point (soakaway) ( 6 ). The
external pipe length should not be more than 3 m.
Further information can be obtained from "BS 6798
Specification for installation of gas–fired boilers of rated
input not exceeding 70 kW net“.

Danger!
Risk of poisoning due to escaping flue gas!
The connection of the condensate drain line to
the waste water piping must not be fixed as the
internal siphon could be sucked dry. Before the
boiler is switched on the siphon must have been
filled with water to prevent flue gas from
leaking via the siphon (see Chap. 6.2.3).

Danger!
Risk of poisoning due to escaping flue gas!
You must fit the enclosed siphon cartridge (1)
in accordance with the separate manual and fill
it with water - see also Chap. 6.2.3.
5.8 Electrical connection
e
Danger!
Risk of fatal electric shock through contact
with live connections!
The electrical installation may only be carried
out by a recognised skilled trade company.
Always switch off the power supply first and
ensure that it cannot be switched back on
unintentionally. Only after this can the
installation be undertaken. Mains connection
terminals L and N remain live even if the boiler
main switch is turned off!
5.8.1 Mains connection
All electrical work shall be carried out by a heating
engineer and shall comply with BS 7671 (IEE
Regulations).
In the Republic of Ireland, reference should be made to
the current edition of the ETCI (Electro-Technical
Council for Ireland) rules.
The boiler is supplied for connection to 230 V, ~ 50 Hz
supply fused at 3 A rating. Connection to the mains
supply shall be made via a fused 3 pin plug to an
unswitched shuttered socket, both complying with the
requirements of BS 1363. (Alternatively, connection may
be made via a 3 A fused double pole isolator having a
contact separation of at least 3 mm in all poles and
supplying the boiler and controllers only). The point of
connection to the mains supply must allow complete
electrical isolation of the boiler and its ancillary
controllers. It should be readily accessible and adjacent
to the boiler. A 3 core flexible cord according to
BS 6500 tables 6,8 or 16 (3 x 0.75 to 3 x 1.5 mm
2
)
should be used.
The nominal voltage of the mains must be 230 V; at
mains voltages greater than 253 V and less than 190 V
the functions may be impaired.
