approximately to a temperature range of 55°C to 82°C.
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 a low setting which will probably be hot enough
forbathingorwashinguprequirements.Forwashingclothes
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.
Pump Overrun
On fully pumped installations the boiler control will continue
to operate the pump for several minutes after boiler shut
down to prevent overheating.
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
Note: When the boiler is first operated, there may be a slight
smell. This will disappear with use.
1. Ensure that the boiler thermostat knob is set to 'O'
Standby (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' position (refer to the time control
literature).
4. Ensure that any room and/or cylinder thermostats are at
a high temperature setting.
5. Turn the boiler thermostat on, set to the required setting
and the flame (Green) L.E.D. will illuminate.
6. Set the time control and any thermostats to their desired
settings.
Reset Button
RSL & CFL Models. The boiler is protected from overheating
by an overheat thermostat. If it operates the boiler goes to
lock-out which is visually indicated by an illuminated Red
LED on the control panel. Wait 5 minutes and restart by
pressing the reset button - Do NOT use excessive force.
CFL models are also protected by a flue thermostat, which
if it operates, will also put the boiler in a lockout condition.
The flue thermostat will operate if it detects down draught or
a flue blockage. Reset as described above.
If the boiler will not light or returns to lock-out, then you
should call your installer or maintenance contractor.
To Shut Off - Short Periods
Turn the boiler thermostat knob to 'O' (Standby) or switch
the programmer to the 'OFF' position. To operate the boiler,
simply turn the boiler thermostat to 'Max' or switch the
programmer 'On'.

Care Of Your Boiler and System During the Guarantee
Period and Beyond
1. Registration of Purchase
It is important to register the purchase of your Potterton
boiler to ensure you receive prompt and efficient handling in
the event your boiler requires attention during the guarantee
period.
To register your guarantee simply complete and detach the
Registration of Purchase form enclosed with these
instructions. It is important to include details of your installer
(if known) and to return the completed form to the Potterton
Registration Department.
2. During the Guarantee Period
In the event of any problems with your system or the
operation of the boiler, you should first call your installer.
If there is a fault with the boiler under guarantee which your
installer is unable to rectify, he/she will call Potterton Service
Operations. For 12 months from the date of installation (or
18 months from the date of manufacture, which ever is
shorter), Potterton will attend to any manufacturing defect,
on the appliance only (not the system or ancillary controls),
free of charge for parts and labour, subject to there being no
misuse or abuse. This does not effect your statutory rights.
Service visits by Potterton Service Operations outside the
terms of the boiler guarantee, will be charged for both parts
and labour at our normal rates for chargeable work. During
the period of the boiler guarantee, Potterton will only be
responsible for the cost of work done by them or on their
instructions by their Agent. We cannot accept any liability for
expenditure or work done by other parties without our
knowledge and/or approval.
3. Safety Check / Routine Maintenance
It is strongly recommended you have your boiler checked
annually for safety and for routine maintenance. This should
be carried out by a CORGI Registered Installer/Service
Agent or Potterton Service Operations to comply with the
requirements of the Gas Safety (Installation & Use)
Regulations 1998.
4. Boiler Breakdown Insurance
We are pleased to offer you the opportunity to protect your
investment once your initial boiler guarantee has expired,
by the payment of an annual premium. You can continue
with this insurance for the normal life of your boiler and you
will find a special 30 day introductory offer for a second year
cover together with a card to register your purchase, as part
of the “User Pack” supplied with your boiler.
If you have not been handed a Registration Card /
additional 2nd Year Breakdown Insurance offer, Please
contact the Potterton Registration Department for a
copy by telephoning [phone].
To Shut Off - Long Periods
Turn the boiler thermostat knob to 'O' (Standby), isolate the
electrical supply at the isolating switch, or pull the electrical
plug out of the wall socket.
Important: Read the section on Frost Precaution.
Important: Gas and electricity are required to operate your
boiler.Its performance will not beaffectedby normal variation
in either 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 the 'On' position.
Overheat Limit Thermostat
The boiler is fitted with a safety thermostat to protect against
overheating of the water. If this thermostat operates the
boiler will lockout and the Red L.E.D. will illuminate. Press
the reset button (
Do Not use excessive pressure ), the Red
L.E.D. will extinguish and the boiler will attempt to re-light.
If the control does not reset, leave the boiler for approx. 15
minutes before pressing the reset button again. 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 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
Service Engineer.
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 or 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.
Note: Although the system can be emptied by using the
drainofftapsinstalled in the pipework around the system,
to empty the boiler, it is necessary to remove the drain
screw which is situated on the heat exchanger casting.
This should only be done by a competent person.
3. Have a low limit thermostat fitted.
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. The low
limit thermostat will not 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 all times
when it would normally be shut off.
