CLEARANCES
Minimum clearances in millimetres.
Your installer will have provided adequate space around the
appliance for safety and servicing. Do not restrict this space by the
addition of cupboards, shelves etc. close to the appliance.
ROOM THERMOSTAT
A room thermostat may be fitted for control of the central heat-
ing temperature. It will be located in one room of the home. The
method of setting a room thermostat varies with the type and manu-
facture. Refer to the instructions supplied with the room thermostat.
THERMOSTATIC RADIATOR VALVES
If thermostatic radiator valves are fitted to the system then they
must conform to the requirements of BS2767. The radiator located in
the room where the room thermostat is sited must be controlled by a
thermostatic radiator valve.
SHOWERS, BIDETS, TAPS AND MIXING
VALVES
Standard hot and cold taps and mixing valves used with the
appliance must be suitable for operating at mains pressure.
Thermostatically controlled shower valves will guard against the flow
of water at too high a temperature.
If using a pressure equalising valve, set the Domestic Hot Water
temperature control knob to the ‘MAX’ position.
Hot and cold mains fed water can be supplied direct to an over-
rim flushing bidet subject to local water company requirements.
With all mains fed systems the flow of water from the individ-
ual taps will vary with the number of outlets operated simultaneous-
ly and the cold water mains supply pressure to the property. Flow bal-
ancing using ‘Ball-o-Fix’ type valves is recommended to avoid an
excessive reduction in flow to individual outlets.

Helpline. 08705 266241
HOT AND COLD FLOW
The flow of water demanded from both hot and cold service out-
lets is dependent upon mains supply, it may not be possible in some
installations to operate all outlets simultaneously.
WATER MAINS FAILURE
It is important to note that in the event of a mains water supply
failure, no tap water will be available until the mains supply is
restored. The appliance can still be used for heating provided that the
system is of the sealed system type. Open vent central heating sys-
tems should be turned off until the supply is restored.
USE IN HARD WATER AREAS
Normally there is no need for scale protection. However, in areas
of exceptionally hard water supply it is recommended that an In-Line
scale inhibitor be fitted.
Installation should be strictly in accordance with the require-
ments of the local Water Company. An isolating valve to facilitate
servicing should be incorporated.
