GENERAL INFORMATION
ROOM THERMOSTAT:
A room temperature controller must be fitted to
control the central heating. Refer to instructions
supplied with the thermostat for information on
siting and setting.
THERMOSTATIC RADIATOR VALVES:
It is recommended that this type of valve is fitted
to all but one of the radiators (or at least those in
the sleeping accommodation). The remaining
radiator, which must be where the room
thermostat is located, should be un-controlled
and must be left open.
SHOWERS, BIDETS, TAPS/MIXING VALVES:
Standard hot and cold taps and mixing valves
must be suitable for operating at the water mains
supply pressure. Only thermostatically controlled
showers are suitable for use with this appliance.
Hot and cold mains fed water can be supplied
directly to an over-rim flushing bidet subject to
local water company requirements.
WATER FLOW:
With all mains fed systems the flow of water
from individual taps will vary with the number of
outlets operated simultaneously and the cold
water 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.
The flow of water demanded from both hot and
cold service outlets is dependent on the mains
water supply, it may not be possible in some
installations to operate all outlets simultaneously.
MAINS WATER FAILURE:
Central heating:
The appliance will operate in central heating mode.
Hot water will not be available until the water
supply is restored.

Read these instructions carefully to get the best
from your appliance.
CENTRAL HEATING SYSTEMS:
During the first few hours of operation of the
central heating system, check that all radiators
are being heated at an even rate.
If the top of a radiator is at a lower temperature
than the bottom then it should be vented by
releasing air through the venting screw at the top
of the radiator. Ask your installer to show you
how this is done. Repeated venting will reduce
the quantity of water in the system and this must
be replenished for safe and satisfactory
operation of the appliance.
When excessive venting or water leaks are found
in the system you must contact a service
engineer to inspect the installation and rectify
any fault.
Only use additives compatible with the appliance
and system. Use of incompatible additives can
cause damage and will invalidate the appliance
guarantee.
Sealed heating systems:
Where the appliance is fitted to a sealed heating
system your installer will inform you of the
minimum and maximum pressure which must be
indicated on the pressure gauge.
Regularly check the pressure is maintained and
contact your installer or maintenance engineer if
there is a noticeable, permanent drop in
pressure. If the system loses pressure it should
be repressurised and the cause of the loss
investigated.
CONDENSATE:
This is a high efficiency appliance using
condensing technology which will under normal
operation produce a regular discharge of
condensate to drain and at times, give out a
plume of water vapour from the flue terminal.
