Introduction
1. Your Potterton Performa 24 Eco HE is a gas fired,
room sealed, powered flue condensing combination
boiler, providing central heating for your home and
mains fed domestic hot water to taps and shower. It
is fully automatic and does not have a pilot light.
2. Priority is given to the hot water mode - when a hot
water tap is turned on the supply of heat to the
central heating circuit is interrupted.
3. Due to the high efficiency and resultant low flue
gas temperature when in condensing mode a white
plume of condensate will be emitted from the
terminal. This will be particularly evident during
periods of low outside temperature.
Operating the Boiler
1. Ensure that the electricity and gas supplies are
turned on. Check that the central heating pressure is
between 0.5 and 1.0 bar (Fig. 3).
2. Turn the On/Off/Reset selector switch either anti-
clockwise from the off position (Fig. 5) to both central
heating and domestic hot water or clockwise to
domestic hot water only.
3. In either position the green “power”neon ( ) will
illuminate (Fig. 4).
4. Position (i) In this position the central heating will
operate according to demand or provide domestic hot
water when a tap or shower is turned on (Fig. 6).
Priority is given to domestic hot water.
5. Position (ii) In this position hot water will be
provided when a tap or shower is turned on (Fig. 7).
6. The boiler will light automatically on demand.
7. The orange “burner”neon ( ) will illuminate
when the boiler is operating and the main burner is
on (Fig. 4).
IMPORTANT: When the selector switch is in the
‘0’ (Off) position the electrical supply to the boiler
is isolated. The boiler will not operate and the
integral timer (if fitted) will require resetting once
the selector switch is set to either Position (i) or
Position (ii).

Fault Indication
1. Your Potterton Performa 24 Eco HE has three neon
indicators. The upper two function as boiler on and
fault indicators.
2. Depending on the nature of the fault the upper two
neons will illuminate, go off or flash.
3. There are five possible combinations, each
indicating one or more fault conditions. These are
described below.
A
The flue or flue terminal is blocked or obstructed in
some way, or there is an internal fault.
If there is no external blockage of the flue that can be
easily removed contact your Installer or Service
Engineer.
B
The circulating pump is faulty or the system pressure
has dropped. Check the system pressure (see page 7).
If the pressure is in the normal range a pump fault is
indicated. Contact your Installer or Service Engineer.
C
A fault on the boiler temperature sensor is indicated.
Contact your Installer or Service Engineer.
D
The primary system or the boiler has overheated.
Allow the boiler to cool. Turn the selector switch fully
anti-clockwise against the spring pressure to the
‘Reset’position and hold for at least 2 seconds.
If this occurs repeatedly contact your Installer or
Service Engineer.
If the boiler does not relight after resetting it is possible
that the flue has overheated. Contact your Installer or
Service Engineer.
E
The burner has failed to light, or incomplete lighting of
the burner has occurred. Turn the selector switch fully
anti-clockwise against the spring pressure to the
‘Reset’position and hold for at least 2 seconds.
If this occurs repeatedly contact your Installer or
Service Engineer.
If the boiler does not relight after resetting blockage of
the condensate drain or trap has occurred. Contact
your Installer or Service Engineer.

Temperature Control
1. Central Heating: The central heating hot water
flow temperature can be adjusted between 30°C (±
5° C) minimum and 85°C (± 5°C) maximum.
2. Turn the control knob clockwise to increase the
temperature (Fig. 8).
3. In normal winter usage we recommend that the
central heating temperature be set at maximum.
4. Domestic Hot Water: The temperature of the
domestic hot water can be adjusted by turning the
control knob clockwise to increase up to a maximum
of 65°C (Fig. 9).
5. The temperature of the water is also dependent on
the water flow rate and the temperature of the mains
water coming into the house.
6. By slightly reducing the flow from the tap the
temperature will increase up to the maximum if
required.
7. The flow rate can be reduced down to as low as 2.5
litre/min. The boiler will still recognise the need to heat
the water.

Central Heating System Pressure
1. The water pressure in the central heating system
is indicated by the pressure gauge.
2. With the system cold and the boiler not operating
the pressure should be between 0.5 and 1.0 bar.
During operation the pressure should not exceed 2.5
bar, and will normally be between 1.0 and 2.0 (Figs.
10 & 11).
3. A pressure of 3 or greater indicates a fault. The
safety pressure relief valve will operate, at a pressure
of 3 (Fig. 12). It is important that your Installer or
Service Engineer is contacted as soon as
possible.
4. The minimum pressure for correct operation is 0.5.
If the pressure falls below 0.5, this may indicate a
leak on the central heating system (Fig. 13).
To Shut Off the Boiler
1. For short periods: Turn the selector switch to the
OFF position (Fig. 14).
2. For long periods: Turn off the selector switch
(Fig. 14), electricity and gas supplies.
If your home is to be left unoccupied for long
periods during cold weather the boiler and whole
system should be drained unless equipped with
frost protection.
3. Your installer will advise you about frost protection
and draining the system.
IMPORTANT: When the selector switch is in
the ‘0’ (Off) position the electrical supply to the
boiler is isolated. The boiler will not operate
and the integral timer (if fitted) will require
resetting once the selector switch is set to
either Position (i) or Position (ii).

Clearances around the Boiler
(Figs. 15 & 16)
1. The minimum clear spaces needed around the boiler
measured from the casing are as follows:
Top - 200mm
Bottom - 200mm
Left side - 5mm
Right Side - 20mm/5mm
Front - 5mm (In Operation)
- 450mm (For Servicing)
* NOTE: The boiler can be operated with a clearance
of 5mm at the right. This is also sufficient for routine
maintenance. However a clearance of 20mm is
required if it is necessary to remove the secondary
heat exchanger. This should be considered when
siting the appliance and in the event of any
subsequent alteration in the area of installation.
2. These areas must not be obstructed in any way.
Blocking the clearance spaces may result in the
boiler overheating and damage may occur.
3. The gas burning compartment of your boiler is
completely sealed from the room in which it is fitted.
Products from the combustion of gas are vented to the
outside through the flue terminal which must be kept
free from obstruction as this would interfere with the
correct operation of the boiler.
4. The boiler may be installed in a cupboard if these
minimum clearances are kept. The compartment should
be large enough to house the boiler and ancillary
equipment only.
5. IT SHOULD NOT BE USED AS A STORAGE
CUPBOARD.
