Caution!
Risk of poisoning from escaping exhaust
gas!
If the condensate trap is not filled with water
before the boiler is switched on, exhaust gas
may escape through the trap.
>
Install the discharge pipework so as not to
interfere with the removal and refitting of
the condensate trap.
>
Do not shorten the discharge pipe for the
pressure release valve supplied.
>
Leave a bottom clearance of at least 180 mm
below the condensate trap for removal and
refitting.

of the heating system (picture shows ecoTEC plus
combination boiler)
The pressure release valve for the heating system is
integrated in the appliance.

Position the seal (

) on to
the pressure release valve.
The discharge pipework should be as short as possible
and installed with a continuous fall away from the boiler.
The pipe should terminate in a position which ensures
that any discharge of water or steam from the valve can-
not create a hazard to persons in or around the
premises, or cause damage to any electrical components
or external wiring, and the point of discharge should be
clearly visible.

All electrical work shall be carried out by a competent
person 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 controls only). The point of
connection to the mains supply must allow complete
electrical isolation of the boiler and its ancillary controls.
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.
