External Controls
We recommend the use of the EHC single channel heat pack for heat-
ing only installations.
For Heating and Hot water installations, we recommend the use of
the EHC twin channel’ Heat Pack’.
The EHC Slim Jim ‘Heat Pack’ will incorporate all the relevant parts
to comply with current building regulations e.g. Circulation pump,
Motorized valves to control the heating and hot water circuits and
Room and cylinder thermostats to control the room and water tem-
peratures. This will also provide boiler interlock. The use of TRV’s
alone will not provide boiler interlock.
We recommend the use of TRV’s, however they must not be used in
the room that has the room thermostat fitted.
Note: This control method is recommended by TACMA (The As-
sociation of Control Manufactures) in order to comply with the cur-
rent Building Regulations.
ALL WIRING MUST BE CARRIED OUT IN ACCORDANCE WITH
CURRENT IEE BS7671 WIRING REGULATIONS
ALL ELECTRICAL CONNECTIONS MUST BE MADE BY A QUALI-
FIED TRADESPERSON
A load check should be carried out to ensure that there is a sufficient
current and voltage for the intended boiler installation. Considera-
tion should be taken into account with regard to the remainder of the
properties load requirements.
All boilers must be protected at the meter position with a double pole
fused switch with a minimum of 3mm contact separation. If the boiler
is not fitted local to the meter position then an isolation switch must
be fitted local to the boiler
THIS APPLIANCE MUST BE EARTHED.
All pipe-work must be earthed in accordance with the IEE BS7671
Wiring Regulations.
After completion of all electrical works, an electrical safety check
should be carried out i.e. short circuit, earth continuity, resistance to
earth and polarity check, and all relevant Test Certificates completed.
Never open the front cover of the boiler until all power supplies to
the boiler have been disconnected.
ELECTRICAL CONNECTIONS
The boiler connections are clearly marked inside the boiler.
L
N E (24hr LIVE)
The 24hr live is the permanent live connection to the boiler from
the mains supply. External controls will require an independent
fused spur supplied from the consumer unit., however this fused spur
should be supplied by the same power source as the boiler itself.
