Introduction

1. Your Potterton Performa System HE is a gas fired,

room sealed, powered flue boiler, providing central

heating and hot water for your home. It is fully

automatic and does not have a pilot light.

2. 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.

Facia Panel

1. The facia panel is behind the hinged lower door

panel. As well as the On/Off/Reset selector switch,

temperature control knob and pressure gauge, the

facia incorporates nine neon indicator lights.

2. Neons 10, 11 & 12 indicate the operational status

of the boiler. Neons 4 to 9 have a dual function,

indicating the temperature of the central heating

water when constantly illuminated. If a fault develops

the appropriate neon will begin to flash.

Air Flow Monitor

1. The boiler is fitted with an air pressure sensing

device. This monitors the flue system.

2. If the ( ) neon illuminates it indicates that the

flue or flue terminal is blocked or obstructed in some

way, or that there is an internal fault. If there is no

external blockage of the flue terminal that can be

easily removed contact your Installer or Service

Engineer (Fig. 11).

Pump Fault or Low Pressure

1. The neon ( ) will illuminate if the circulating

pump is faulty or the system pressure drops below the

minimum requirement (Fig. 11).

2. Check the pressure gauge as described on page 8.

If the pressure is in the normal range, a pump fault is

indicated. Contact your Installer or Service Engineer

to determine the nature of the fault.

Sensor Fault

1. When either of the the ( ) neons is illuminated a

fault on one of the temperature sensors is indicated

(Fig. 11). Contact your Installer or Service Engineer.

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 0.2 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.

13 & 14).

3. A pressure of 3 or greater indicates a fault. The

safety pressure relief valve will operate, at a pressure

of 3 (Fig. 15). It is important that your Installer or

Service Engineer is contacted as soon as

possible.

4. The minimum pressure for correct operation is 0.2.

If the pressure falls below 0.2, this may indicate a

leak on the central heating system (Fig. 16).

To Shut Off the Boiler

1. For short periods: Turn the selector switch to the

Off position (Fig. 17).

2. For long periods: Turn off the selector switch

(Fig.17), 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 there is

additional 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.

Frost Protection Mode

1. The frost protection feature will operate when the

selector switch is in the On position.

The gas and electrical supplies to the boiler must be

on and then system pressure be within the range

described above.

2. If the system temperature falls below 5°C, then the

boiler will fire until the water temperature has been

raised.

3. Further frost protection can be incorporated by

using a frost thermostat to protect the whole system.

Clearances around the Boiler (Figs. 18 & 19)

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.
