WIRING INSTRUCTIONS
All electrical work must be carried out in accordance with
current IEE wiring regulations.
Before commencing installation check power supply to
property to ensure that there is sufficient current and
voltage available for size of boiler fitted. Take into
account requirements of other electrical appliances, the
boiler must be connected to the mains supply by means
of a double pole linked switch with 3mm contact gap in
both poles.
IMPORTANT:
After completing electrical installation work preliminary
safety checks should be carried out as described in
BS 7671:2001
The electrical supply requirements:
The 6kW boiler supply should meet the requirements of
EN61000-3.3.
The 9kW boiler must be installed in premises having a
service supply > 100A per phase and meet the
requirements of IEC 60417-5855.
The 12kW boiler must be installed in premises having a
system impedance of not more than 0.1939 + 0.1939Ω.
A double pole RCD with a trip level sensitivity of 30ma can
be used capable of breaking full load current to
BS EN61008: 1994
NOTE: RCD unit can be used as the isolating switch if
mounted close enough to the boiler.
Miniature circuit breakers MCB’s
MUST be fitted between
RCD unit and boiler and RCD and any external controls.
Refer to technical specification. For MCB ratings refer to
wiring diagram.
It is important the correct size MCB is used in the supply
from the RCD to the boiler.
ELECTRICAL CONNECTIONS
WARNING: THIS APPLIANCE MUST BE EARTHED.
The mains connection block is located inside the boiler on
a bracket at the bottom left hand side of the boiler which
can be directly wired to the boiler MCB. Use the correctly
rated cable.
IMPORTANT: CORRECT POLARITY MUST BE OBSERVED
WHEN BRINGING THE MAINS SUPPLY INTO THE BOILER.
