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.
NOTE: If the appliance is to be enclosed after the
installation then the instructions given in Section 4, Siting
the Appliance, of the Installation Book MUST be followed.
NOTE: Do not place anything on top of the appliance.
If the appliance is fitted in a compartment do not use the
compartment for storage purposes unless it conforms to the
requirements of BS 6798. It is essential that the airing space is
separated from the boiler space by a perforated non-combustible
partition as described in BS 6798.
ROOM THERMOSTAT
A room thermostat must be fitted for control of the central
heating temperature. It will be located in one room of the home. The
method of setting a room thermostat varies with the type and
manufacture. 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. It is advisable to leave
one valve permanently set at maximum to prevent the boiler short
cycling.
SHOWERS, BIDETS, TAPS AND MIXING
VALVES
Standard hot and cold taps and mixing valves used with the
appliance must be suitable for operating at the available mains
pressure.
Thermostatically controlled shower valves will guard against the
flow of water at too high a temperature.
Hot and cold mains fed water can be supplied direct to an
overrim flushing bidet subject to local water company requirements.
With all mains fed systems the flow of water from the individual
taps will vary with the number of outlets operated simultaneously
and the cold water mains supply pressure to the property. Flow
balancing using ‘Ball-o-Fix’ type valves is recommended to avoid an
excessive reduction in flow to individual outlets.
For further information contact Worcester Heat Systems
Technical Helpline.
HOT AND COLD FLOW
The flow of water demanded from both hot and cold service
outlets is dependent upon mains supply and 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 as it is connected
to a sealed system.
