How your combination boiler works
Production of hot water
This boiler is designed to give hot water at different tem-
peratures and is fitted with a temperature selector
(fig. 1 FL
To obtain the hottest water turn the selector knob fully in
the ‘+’ direction. In this position the burner may cycle high
to low flame - this is normal. Greater amounts of cooler
water can be obtained by turning the selector knob to-
wards the ‘-’ sign.
Heating
The boiler is automatically self adjusting when on central
heating. It is normal for the boiler to stay alight for exten-
ded periods with the flame height reduced.
The gas will be at high flame when the maximum output is
required, in cold weather or on start up.
Controls
Installation without a room thermostat
Set the boiler thermostat (fig. 1 B)as required depending
on the desired room temperature. To increase the heat
turn to ‘+‘,to reduce the heat turn to ‘-‘. The temperature
gauge (fig. 1 E) indicates the temperature of the water
going to the radiators.
Installation with a room thermostat
- Set the control on the room thermostat to the desired
temperature which will automatically control the firing
of the boiler to give the chosen room temperature.
- During cold weather, the boiler thermostat (fig. 1 B)
should be left on maximum, turned to position ‘+‘.
- In mild weather jt is recommended that the thermostat
isplaced in an intermediate position.
To isolate the heating circuit during the summer
In some installations it is possible,after the boiler has been
operating continuously for a period providing hot water,
to get gravity circulation in the heating pipes. It will be
noticed that the pipes are getting hot and eventually the
first radiator will heat up. To avoid this, isolate asfollows :
- Switch to ‘hot water only’ and closethe valve (fig. 2 J)on
the heating flow.
- Do not forget to open the valve at the start of the hea-
ting seasonwhen the selector switch is set to ‘hot water
+ central heating’.
Pressure gauge (fig. 1 C)
This shows the water pressure in the central heating pipe
work. When cold it should read not lessthan 1 bar. This will
increase as the system heats up. A pressure relief valve
will operate at 3 bar. Your installer will be able to repressu-
rise the system if necessary.
Selector switch
When set for hot water only (position ‘I’) the boiler will only
operate on demand for hot water.
When set to hot water + central heating (position ‘II’) the
boiler will supply your central heating requirements but
will give priority to hot water demands. The central hea-
ting supply will be temporarily interrupted when drawing
hot water but this will have no noticeable effect on the
heating levelsfor normal quantities of hot water supply.
lighting the boiler
I) Switch on the electricity.
2) Turn the lever on the gas service tap to the left
(fig. 2 G).
3) Set the selector switch (fig. 1 A) to required position.
For hot water only ‘I’ or for hot water + central heating
‘II’.
The fan will start up and the pump will run if set to hot
water + central heating ‘II’.

4) Pressthe igniter button (fig. 1 D)fully in.
- The fan will change to high speed to purge the com-
bustion chamber, and the pump will stop.
- After approximately 14 seconds the spark generator
creates a continuous spark to light the pilot.
- When the pilot is alight, viewed through the sight
glass, wait a further 5 seconds before slowly relea-
singthe button.
- If the pilot goes out wait at least 3 minutes and re-
peat asabove.
5) If set to hot water + central heating ‘II’, check that the
flow isolating valve (fig. 2 J) is fully open (turn anti-
clockwise).
To turnofftheboiler
Set the selector switch to the centre position off ‘0’. Turn
off the gas by turning the lever (fig. 2 G)on the gas servi-
ce tap to the right. Turn off the electricity supply.
To turn off the boiler leaving the pilot alight
Set the selector switch (fig. 1 A)to hot water only position
‘I’ turn off domestic water tap (fig. 2 H)under the appliance
and leaveelectricity supply on.
Frost precautions
Providing the boiler is not isolated from the electricity sup-
ply it hasautomatic protection from damage bv frost.
Overheating
If the pilot light or gas flame should go out whilst the boi-
ler isset to operate :
- Wait 3 minutes before relighting.
If the boiler goes out again this may be due to the over-
heat safety device operating.
- If this persists contact your service engineer.
Cleaning
The surface of the boiler may be cleaned using soap,
water and a soft cloth or a non-abrasive cleaner.
Service
To ensure that the appliance continues to work efficiently
and hasa long life, it is important that it isserviced annually.
Ask your installer or local Gas Region for details of a
regular service scheme.
This appliance is suitable for use with most showers and
automatic washing machines.

‘Warning’
If the pilot is extinguished for any reason wait at least 3
minutes before attempting to relight.
Electrical connections
The electrical supply connection must be made to a 240 V
50 Hz supply. The appliance must be protected by a 3 A
fuse. If a plug (BS 1363) is used or anv other type a 3 A
fuse must be fitted inthe circuit.
This appliance must be earthed
To connect a plug
As the colour coding of the wires in the mains feed of the
appliance may not correspond with the colour marking
identification of your plug, proceed asfollows :
- The wire which is coloured green/yellow must be
connected to the terminal in the plug marked with the
