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.

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.
