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
(BS 1363) 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.

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 O (OFF}, 1, 2, 3, 4, 5 or Max. The graduations 1 to
Max. correspond approximately to a temperature range of 55°C to 82°C (130°F -180°F).
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 con-
trolled, the stored hot water could be at a temperature that could scald, i.e. about 82°C (180ºF).
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 contro1s 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 contrql, 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.
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.
1. Check that the gas, electricity and water are all turned on at the main supply.
2. Check that the time control, if fitted, is in an 'ON' period.
3. Check that all thermostats in the system are not on low settings.
4. Overheat Limit Thermostat
The boiler is fitted with a safety thermostat to protect against overheating of the water. Should the boiler fail
to light, allow it to cool and press the reset button. Access to the button is through a hole in the underside of
the controls cover, see illustration on front page. If the problem persists, turn off the boiler and consult your
local Gas Region or Service Engineer.
Note: Interruption of the electrical supply to the boiler may also cause the overheat limit thermostat to
operate.
Having checked these points, run through the lighting procedure once more and if the boiler still fails to light, call in
your local service engineer.
CARE OF YOUR BOI LER AND SYSTEM
Regular skilled servicing is required to keep your boiler operating safely and efficiently throughout its long working
life.
It is also advisable to have the whole heating system checked over annually, so that excessive costs are not incurred
by such things as air temperature thermostats or radiator valves getting out of adjustment. Servicing should be

5
carried out by a trained service engineer, and it is suggested that an annual contract be arranged. Contact your local
Potterton regional service office, or return the post card attached to these instructions for further information.
The outside of the boiler casing can be wiped when necessary using a damp cloth to remove finger marks etc. Do
not use an abrasive material.
FROST PRECAUTIONS
If your boiler has to be shut down for several hours or more during very cold weather, it may be in danger of
freezing, due to its position, i.e. it may be in an outhouse or part of the pipework may be vulnerable to frost. To
avoid freezing, various methods of protection can be used:-
1. Insulation of the boiler and pipework, taking care not to impede any ventilation air supply.
2. Completely draining the water system if not in use for long periods. On a sealed system, draining and refilling
must be carried out by a competent person, e.g. your Service Engineer.
NOTE:
Although the system can be emptied by using the drain-off taps installed in the pipework around the system,
to empty the boiler, it is necessary to remove the drain cap situated within the boiler case. This operation is
best left to your Service Engineer.
3. Having a low thermostat fitted. Seek advice from your installer.
NOTE:
If a low limit thermostat has been fitted, it cannot operate if the boiler is completely shut down and the
electricity supply turned off. In this instance, the system will have no protection and one of the other methods
must be used.
4. Where no frost protection is provided it may be necessary to run the boiler at low thermostat settings at times
when it would normally be shut off.
