The Central Heating and Hot Water you need will be available
when the gas and electricity supplies to the boiler are turned
on with the timer and other heating controls in your system
set correctly.
Other heating controls are items such as room
thermostats, cylinder thermostats and thermostatic
radiator valves. To give the most energy efficient
performance these controls can switch your boiler on and
off even when your timer is on. Instructions on how to use
your programmer and other heating controls should have
been supplied with the items. Potterton also produce a
guide ‘How to get the best out of your NEW Central
Heating System’. Telephone our Literature Hotline on
08706 060 623 to request your free copy.
With the gas and electricity supplies to the boiler turned on
and your programmer and other heating controls set correctly,
you only need to set the temperature control knob to the
desired level.
1. Pull the door panel down.
2. Confirm ‘Mains On’ light is on or flashing.
3. Turn the temperature control knob to adjust the radiator
surface temperature and hot water tap temperature
between approximately 63°C and 82°C.
4. When there is a call for heat the ‘Burner On’ light will flash
and after several seconds the burner will light
automatically. The 'Burner On' light will be on whilst water
is being heated.

Resetting
If the ‘Lockout’light is on or flashing the boiler will need
resetting.
1. Turn the temperature control knob to ( ) position.
2. Wait until the ‘Lockout’light goes off.
3. Turn the temperature control knob to the required setting.
The boiler should reset and return to normal operation.
4. If the boiler does not reset:-
•Check the fault indicators (see label on door panel). If
the boiler has Overheat or Circulation indicators lit,
wait 15 minutes for the boiler to cool and reset again.
•Check that the gas and water supplies to the boiler
have not been inadvertently turned off.
5. If the boiler still fails to reset or resets then returns to
lockout, there is a fault that should be attended to by a
competent person.
Competent Person - A person who works for a
CORGI registered company and holding current
certificates in the relevant ACS modules, or valid
ACoP equivalents, is deemed competent.
In the Republic of Ireland this must be carried out by
a competent person as stated in Irish Standard (I.S.)
813 “Domestic Gas Installations”.
To Turn Off
If you need to turn the boiler off, turn either the
temperature control knob to ( ) position or
set the programmer/timer to Off (if fitted).
Do not switch off the main electrical supply to
the boiler whilst the ‘Burner On’light is on.
Boiler Protection
The protection systems shown below will
always be working whilst the gas and
electricity supplies to the boiler are on.
•To ensure the boiler is protected during very
cold conditions a frost protection feature is
built in to the boiler. If the boiler temperature
falls below 4°C the boiler will fire until a
temperature of 15°C is reached.
•The boiler incorporates a built in pump
protection feature which continually monitors
the time since the pump last operated. The
pump will run for around 2 minutes if it has
not run in the last 24 hours. This may occur
during the night when your heating controls
are set to off.
•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 ‘Lockout’(Red) light will flash
once a second. The boiler will require
resetting before it will re-light.
•A frost thermostat may have been fitted to
your system. Your installer will have advised
you of this.
