DRAINING
Key-operated drain taps to BS 2879 should be provided in
accessible positions in all low parts of the system. However,
it should be noted that there may be short sections of
pipework, e.g. when passing under doorways, that may not
be possible to drain.
INTERNAL PUMP THERMOSTAT
This appliance has the capability for switching the circulating
pump ‘on’ and ‘off’ automatically. To wire in the pump,
connect the phase to terminal marked CIRC Pump (L) and
connect the Neutral to terminal marked CIRC Pump (N). The
earth wire is to be connected into the earth block.
The connection circuit board/control panel is located within
the appliance beneath the warming oven. (See
WATER CIRCUIT TEMPERATURE
The return water temperature should be maintained at not
less than 50°C (122°F) so as to avoid condensation forming
within the boiler.
CARE FOR YOUR CENTRAL HEATING SYSTEM
The use of suitable corrosion inhibitors and anti freeze
solution in your heating system is essential to minimise black
oxide, sludge and scale build-up, which effects efficiency.
In hard water areas the use of a suitable limescale preventer /
remover is advised.
Use only quantities specified by the water treatment product
manufacturer. Only add to the heating system after flushing
and finally refilling. Refer to BS 7953.
INDIRECT DOMESTIC CYLINDER
The cooker must only be connected to an indirect cylinder
of no less than 180 litres using 28mm diameter flow and
return piping. It is recommended that the cylinder is lagged
together with pipework with runs in excess of 4 meters (12’).
