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.
SAFETY
The boiler should have the following minimum clearances
for Safety and Maintenance, 610mm (2ft) 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 O (OFF), 1,2,3,4,5 or Max. The graduations 1
to Max. correspond approximately to a temperature range
of 55ºC to 82ºC (130ºF -180ºF).
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 82ºC (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 controls should be supplied with them.
TO LIGHT
1. Ensure that the boiler thermostat knob is at ‘O’ (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.
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 ‘O’, 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 ‘O’, 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.
1Check 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 the thermostats in the system are not on
low settings.
