(NOTE: When the pump is running the gauge under the boiler may show a slightly differnt reading to the display)

If you don’t know what you need to do to get the boiler to light, or need help with the system and controls, contact your installer as soon as possible

Temperature / Care of the Boiler

To increase or decrease the boiler temperature

1. Press the ( ) to increase the CH temperature.

2. See 3.1 or 3.2 to set the required temperature.

Cleaning the Outercase

The painted panels should be wiped with a damp cloth and then dried completely. DO NOT USE ABRASIVE CLEANING AGENTS.

Boiler Frost Protection

1. The boiler incorporates an integral frost protection feature that will operate in both CH & DHW modes, and also when in standby ( displayed).
2. If the boiler temperature falls below 5° C, then the boiler will operate until the water temperature has been raised.
3. Further protection may be required for the system. Consult your installer for details.

Information Display

The table opposite shows information that can be displayed by pressing the button.

The button can be pressed so that the display shows the following information:-

1. press – ‘00’ alternates with Sub-Code (only when fault on boiler) or ‘000’
2. presses – ‘01’ alternates with CH Temperature
3. presses – ‘02’ alternates with Outside Temperature (where Sensor fitted)

Repressuring System & ‘Service Due

Central Heating System Pressure

1. The normal operating water pressure is between 1 and 2.5 bar (Fig. 1). If the pressure exceeds 3 bar the safety pressure valve will operate and a fault is indicated (E117 displayed). Contact your installer.
   

2. It may be necessary to depressurize the system occasionally (as Fig. 2 or E118 displayed). A filling device (the filling loop) will be fitted on the system. This will be on the boiler itself, or on pipework near to the boiler.
   

3. If you are unsure of its position, or cannot identify it, consult the installer who fitted the boiler.

4. The filling loop consists of two taps and a separate copper pipe with connection fittings.

5. Only when repressurising should the copper pipe be connected between the two taps. Ensure that the nuts on the pipe ends are tightened onto the taps.

6. Fully open one of the taps first, and then while watching the pressure gauge, carefully open the second tap.

7. The system pressure is shown at all times on the gauge under the boiler and can be viewed on the display when there is power to the boiler.

8. To display the water pressure press 6 times. ‘05’ will alternate with the system pressure. (NOTE: When the pump is running the gauge under the boiler may show a slightly differnt reading to the display)

9. When the needle on the gauge or figures on the display indicate 1 or more turn both taps off.

10. Disconnect the copper pipe from the taps (a small amount of water may be present) and remove it. Keep the pipe in a safe place for future use.

‘Service Due’ Message ‘Sd’ will show for three seconds, alternating with the boiler temperature

‘Service Due’ Message

1. After 11 months operation the ‘Service Due’ message will be shown on the boiler display.
2. Please contact your Installer, Annual Service Provider or ‘heateam’ – The Service Division of Baxi to arrange your Annual Service. You can contact ‘heateam’ on telephone number 08448 711 545 or visit www.heateam.co.uk
