2.0 Introduction

2.1

Introduction

1. Your Potterton Performa System 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.

2.2

Facia Panel

1. The facia panel is behind the hinged lower door. As well as the On/Off/Reset selector switch, central heating temperature control knob and pressure gauge, the facia incorporates ten neon indicator lights.

2. Neons 10 to 13 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. Refer to Sections 3.3 to 3.7.

3.0 Operating the Boiler

3.1

Operating the Boiler

1. Ensure that the electricity and gas supplies are turned on. Check that the central heating pressure is between 0.2 and 1.0 bar (Fig. 4).

2. Turn the On/Off/Reset selector switch either anti-clockwise from the off position (Fig. 6) to both central heating and hot water or clockwise to domestic hot water only.

3. In either position the green power on indicator

( ) will illuminate (Fig. 5).

4. Position (i) In this position the boiler will provide central heating or domestic hot water according to demand (Fig. 7). The central heating

( ) or hot water neon ( ) will illuminate (Fig. 5).

Neons 4 to 9 will illuminate as the temperature rises.

5. Position (ii) In this position the domestic hot water will be heated as demanded (Fig. 8). The hot water neon will illuminate ( ). The central heating will not operate even if timers, room thermostat etc. are calling for heat.

6. Depending upon the system, domestic hot water may be given priority when the selector switch is in Position (i).

7. The boiler will light automatically on demand.

8. The orange burner on neon ( ) will illuminate when the boiler is operating and the main burner is on (Fig. 5).

IMPORTANT: When the selector switch is in the ‘ 0 ’ (Off) position the electrical supply to the boiler is isolated. The boiler will not operate.

3.2

Temperature Control

1. The 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. 9).

3. In normal winter usage we recommend that the temperature be set at maximum.

3.3

Flame Failure Reset

1. The red flame failure neon ( ) will illuminate in the event of the burner failing to light, or when incomplete lighting of the burner occurs (Fig. 10).

2. Turn the selector switch fully anti-clockwise against the spring pressure to the reset position

(R) and release (Fig. 11). Set the selector to the required position to light the boiler.

3. If the flame failure light illuminates repeatedly a fault is indicated. Your Service Engineer should be contacted as soon as possible.

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 Service

Engineer (Fig. 12).

3.5

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. 12).

2. Check the pressure gauge as described in

Section 3.9. If the pressure is in the normal range, a pump fault is indicated. Contact your Service

Engineer to determine the nature of the fault.

3.6

Sensor Fault

1. When the ( ) or ( ) neon is illuminated a fault on the central heating or hot water temperature sensor is indicated (Fig. 11). Contact your Service Engineer.

3.7

Pump Protection

1. With the selector switch in either Position (i) or

Position (ii) (Figs. 13 & 14) the pump will automatically operate for 1 minute in every 24 hours to prevent sticking.

3.8

Safety Thermostat

1. Your Potterton Performa System is fitted with an additional safety device, which shuts down the boiler in the event of the system or the boiler overheating. The safety thermostat neon ( ) will light in this instance (Fig. 12).

2. To reset: Turn the selector fully anti-clockwise against the spring pressure to the reset position

( R ) and release (Fig. 13).

3. If the safety thermostat operates repeatedly, causing boiler shutdown, a fault is indicated. Your

Service Engineer should be contacted as soon as possible.

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. 14 & 15).

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

The safety pressure relief valve will operate, at a pressure of 3 (Fig. 16). It is important that your

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. 17).

5. The system must be re-pressurised by your

Service Engineer.

3.10

To Shut Off the Boiler

1. For short periods: Turn the selector switch to the Off position (Fig. 18).

2. For long periods: Turn off the selector switch

(Fig.18), 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.

3.11

Frost Protection Mode

1. The frost protection feature will operate when the selector switch is in Position (i).

The gas and electrical supplies to the boiler must be on and then system pressure be within the range described in Section 3.9.

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.

4.0 Clearances and Check List

4.1

Clearances around the Boiler

(Figs. 19 & 20)

1. The minimum clear spaces needed around the boiler measured from the casing are as follows:

Top

Bottom

Both sides -

Front -

-

-

200mm

200mm

5mm

5mm

450mm

(In Operation)

(For Servicing)

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.

4.2

Check List

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

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 in the On Position

(giving a green “ Power On ” neon) ?

c) Is the red “ Flame Failure ” neon lit ?

Turn the On/Off/Reset selector fully anti- clockwise.

d) Is the gas supply on ?

e) Is the system pressure correct ?

f) Is the boiler temperature control set high enough ?

g) Is the time clock (if fitted) calling for heat ?

h) Is the room thermostat (if fitted) set high enough ?

i) Are the radiator valves open ?
