INTRODUCTION
The information given on this card will help you to obtain the
maximum comfort from your boiler with the minimum trouble
and cost. Your boiler is fully automatic in operation and requires
very little attention apart from setting the thermostat.
Regular skilled servicing is required to maintain the safe and
efficient operation of your boiler throughout its long working life.
Further information on this subject is given at a later stage.
ELECTRICITY SUPPLY
WARNING: THIS APPLIANCE MUST BE EARTHED
Connection shall be made to a 240V—50 Hz supply.
The appliance must be protected by a 3 amp fuse if a
13 amp (B51363) plug is used or if any other type of
plug is used by a 5 amp fuse in the circuit.
TO CONNECT A PLUG
As the colour of the wires in the mains lead of the appliance
may not correspond with the coloured markings identifying the
terminals in your plug, proceed as follows:— The wire which is
coloured green-and-yellow must be connected to the terminal in
the plug which is marked with the letter E or by the earth symbol
or coloured green or green-and-yellow.
The wire which is coloured blue must be connected to the
terminal which is marked with the letter N or coloured black.
The wire which is coloured brown must be connected to the
terminal which is marked with the letter L or coloured red.
SAFETY
The boiler should have the following minimum clearances for
Safety and Maintenance, 610mm (2ff) at the front of the boiler,
5mm (3/l6in) each side, 100mm (4in) at the bottom, 50mm (2in)
at the top.
Flammable materials must not be stored in close proximity to
the boiler.
Ensure that the flue terminal outside the house, does not
become obstructed, particularly by foliage.
THE BOILER THERMOSTAT
The boiler thermostat enables you to control the temperature of
the water as it leaves the boiler and is also used for turning the
boiler on and off. The thermostat knob can be set to 0 (OFF),
1,2,3,4,5 or Max. The graduations 1 to Max. correspond
approximately to a temperature range of 55C to 82 C (130T—
180T).
During the summer months, when the boiler is only being used
to supply stored domestic hot water and there is no independent
hot water temperature control, the thermostat can be set to
position 1 or 2 which will probably be hot enough for bathing or
washing up requirements. For washing clothes, a higher setting
may be necessary.
In winter weather, when central heating is required, the
thermostat knob can be turned up higher but it must be
remembered that unless the temperature of the water in the
domestic hot water cylinder is independently controlled, the
stored hot water could be at a temperature that could scald, i.e.
about 82C (180F).

OTHER CONTROLS
A Potterton Electronic Programmer or other type of clock may
have been fitted in your system, together with room and/or
cylinder thermostats. Full instructions on the use of these
controls should be supplied with them.
TO LIGHT
1.
Ensure that the boiler thermostat knob is at '0' (fully anti-
clockwise).
2.
Switch 'ON' the main electricity supply.
3.
Ensure the electronic programmer or other time control, if
fitted, is in an 'ON' period (refer to time control literature).
4.
Ensure that any room and/or cylinder thermostats are at a
high temperature setting.
Proceed as follows:—
Turn the boiler thermostat on and to the required
setting. After a short period, the boiler will light: the main burner
can be seen through the sight glass on the front of the boiler.
Set the time control and any thermostats, where fitted, to their
desired settings. On the first main burner ignition of a newly
installed boiler, supplied from a new bulk gas storage
installation, some noise may be emitted due to air in the
pipeline. This noise may persist on subsequent boiler ignitions
for a day or two according to usage, until any air remaining in
the supply system has been purged.
NOTE:- When the boiler is first lit, there may be a slight smell.
This will disappear with use.
TO SHUT THE BOILER OFF
Turn the boiler thermostat knob to '0', or switch the external
programmer to the 'OFF' position. To relight the boiler, simply
turn the boiler thermostat 'ON' or switch the programmer to the
'ON' position.
FOR LONGER SHUT DOWN PERIODS
Turn the boiler thermostat to '0', isolate the electrical supply at
the isolating switch, or pull the plug out of its socket.
NOTE:
If the system is fitted with a low limit thermostat and protection
of the system is required during cold weather, all that is
required, is for the programmer to be turned to the 'OFF'
position. This will allow the boiler to cycle if the temperature
within the house becomes too low.
IMPORTANT
Gas and electricity are required to operate your boiler. Its
performance will not be affected by normal variation in gas or
electricity supply, but a gas or electricity failure will put the boiler
out of operation. It will automatically re-start when the supply is
restored, provided that the time clock and/or thermostats are in
an 'ON' position.
In the event of your boiler not working, there are several checks
you should carry out before calling in a service engineer, as this
could save you unnecessary expense.
