3 Years Free Warranty - register today

To receive your 3 years free warranty please complete the form supplied with the boiler or simply call heateam, the service division of

Baxi Potterton on 08706 017 017.

Dear User

Thank you for choosing a Potterton Combination boiler. The following instructions are simple basic steps that you can take to ensure years of trouble free heating and hot water for your home.

Points to note

This 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.

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.

The energy efficiency of your new boiler means that water vapour condenses inside the boiler itself. This water is taken away from the boiler to a suitable drain.

At times of low outside temperature a white plume can be seen at the boiler flue terminal on the outside of your house. This is mainly water vapour due to your boiler condensing and is normal.

Warranty

heateam the service division of Baxi Potterton provide a 3 year free warranty for your peace of mind. Once your boiler is registered with us and in the unlikely event your boiler develops a fault and your installer is unable to assist, heateam will provide a free service to you provided the boiler is under 3 years old.

Otherwise heateam will offer a competitive fixed price repair rate including parts, labour and VAT. To arrange an engineer visit either in warranty or out, please call heateam on 08706 017 017.

It would help if you had your boiler serial number when you call, the serial number is shown on the back cover of this guide.

Annual Service

To ensure you receive the maximum efficiency from your boiler we recommend your boiler has an annual service so you and your family can continue to enjoy heating and hot water comfort.

To arrange an annual service from one of our Baxi Potterton heating experts, please call heateam on 08706 017 017 to arrange a visit convenient to you.

Benchmark Commissioning Check List

Please ensure that your installer hands you the boiler Installation

& Service Instructions with the “Benchmark” Commissioning

Checklist sections completed. The details in the Checklist will be required in the event of any warranty work. Keep the instructions in a safe place and ensure that the Service Interval Record at the back is completed at each service visit.

Operating the Boiler

The Central Heating and Hot Water you need will be available when the gas and electricity supplies to the boiler are turned on with the timer and other heating controls in your system set correctly.

Other heating controls are items such as room thermostats, cylinder thermostats and thermostatic radiator valves. To give the most energy efficient performance these controls can switch your boiler on and off even when your timer is on. Instructions on how to use your programmer and other heating controls should have been supplied with the items.

Baxi Potterton also produce a guide ‘How to get the best out of your NEW Central Heating

System’. Telephone our Literature Hotline on

08706 060 623 to request your free copy.

Fault Indication

1. If a fault occurs on the boiler an error code may be shown on the facia display.

2. The codes are either two or three digit, preceded by the letter 'E'. For example, code E133 will be displayed by 'E1' alternating with '33'. E50 is shown as 'E' then '50'.

3. E20, E28, E50, E125 & E160 indicate faulty components. You should make a note of the displayed error code and contact your installer or service engineer.

4. If E110 or E130 is displayed overheat of the primary water or flue system has occurred. Turn the selector switch to the reset position and hold for at least 5 seconds. If the boiler does not relight, or the code is displayed regularly contact your installer or service engineer.

5. E119 is displayed when the primary water pressure is less than 0.5 bar. After repressurising the system the boiler should operate. Your installer will be able to advise you about the method of repressurising. See page 6 for further details.

6. E133 indicates that the gas supply has been interrupted, ignition has failed or the flame has not been detected. Ensure that the gas supply has not been turned off, and turn the selector switch to the reset position and hold for at least 5 seconds. If the boiler does not relight, or the code is displayed regularly contact your installer or service engineer.

Resetting (Fig. 8)

1. To reset the boiler turn the selector switch fully anticlockwise against the spring pressure for approximately 5 seconds and release.

Pump Protection

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

Position (ii) (Figs. 7 & 9) the pump will automatically operate for 1 minute in every 24 hours to prevent sticking.

3-Way Valve - Anti-sticking

1. If there is no demand for heat in a 24 hour period, the 3-way valve will be operated once to help prevent sticking.

Temperature Control

1. Central Heating: The central heating hot water flow temperature can be adjusted between 25° C minimum and 80° C maximum.

2. Turn the control knob clockwise to increase the temperature (Fig. 10). As the control knob is turned the selected temperature is displayed for approximately 4 seconds. The display then reverts to the current boiler output temperature.

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 60° C (Fig. 11). As the control knob is turned the selected temperature is displayed for approximately 4 seconds. The display then reverts to the current boiler output temperature.

5. The temperature of the water is also dependent on the water flow rate and the temperature of the mains 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

2.0 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 at least 0.5 bar.

During operation the pressure should not exceed

2.5 bar, and will normally be between 1.0 and 2.0

(Figs. 12 & 13).

3. A pressure of 3 or greater indicates a fault. The safety pressure relief valve will operate, at a pressure of 3 (Fig. 14). 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.

15). Error Code E119 will be shown on the display.

To Shut Off the Boiler

1. For short periods: Turn the selector switch to the OFF position (Fig. 16).

2. For long periods: Turn off the selector switch

(Fig.16), 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 and the integral timer will require resetting once the selector switch is set to either Position (i) or

Position (ii).

Boiler Frost Protection Mode

1. The frost protection feature will operate when the selector switch is in the central heating and domestic hot water mode.

The gas and electrical supplies to the boiler must be on and the system pressure must be within the range described above.

2. If the system temperature falls below 5°C, then the boiler will operate until the water temperature has been raised.

Setting the Timer

The Electro-Mechanical Timer allows the central heating system to be set every 15 minutes.

Using the three position switch the timer will allow either constant operation, timed operation or central heating off.

Move the switch button by sliding to the desired position.

Three position switch (Fig. 17)

Constant (Top position): The heating will be on constantly irrespective of the position of the tappets.The heating will be controlled by the main thermostat on the appliance and/or any external controls.

Timed (Central position): The heating will operate according to the position of the tappets and be controlled as above.

0

Off (Bottom position): No central heating.

Domestic hot water will operate on demand.

To set the time of day

Turn the timer outer bezel clockwise, to align the pointer with the correct time to the nearest 15 minutes ensuring that A.M./P.M. is considered.

Do not at any time attempt to turn the bezel anti-clockwise.

To set the timed heating program

Decide which times of the day the central heating is required.

The heating will operate when the white tappets are set to the outer edge of the bezel.

To ensure the heating stays OFF set the required tappets inwards towards the centre of the bezel.

Each tappet represents 15 minutes.

For example: If the heating is not required between

10 A.M. and 11 A.M. the four tappets anticlockwise from the 10 A.M. will be set inwards (Fig. 18).
