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.

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.

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.

A fault on the boiler temperature sensor is indicated.

Contact your Installer or Service Engineer.

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.

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.

Check List

1. If a fault develops, or is suspected, call your Installer

or Service Engineer as soon as possible.

2. Go through the following check list before you make

contact.

a) Is the electricity supply on ?

b) Is the selector switch on (giving a green “Power ON”

light) and set for both Central Heating and

Domestic Hot Water ?

c) Is the red “Flame Failure”indicator lit ? Turn the
