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
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.
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'.
