3.0 Temperature Adjustment & Care of the Boiler

3.1 To increase or decrease the boiler temperature

1. Press to increase the Central Heating temperature.

2. Press to decrease the Central Heating temperature.

NOTE: An overheat thermostat (NTC) is positioned in the heat exchanger which shuts down the appliance if the boiler temperature exceeds 100°C. Press button to reestablish normal operating conditions.

3.2 To increase or decrease the domestic hot water

temperature

1. Press to increase the Domestic Hot Water temperature.

2. Press to decrease the Domestic Hot Water temperature.

3.3 Summer - Winter - Only Heating Mode

1. Press button until the required mode appears:-

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

3.4 Cleaning the Outer Case

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

AGENTS.

3.5 Boiler Frost Protection

1. The boiler incorporates an integral frost protection feature that will operate in both Central Heating & Domestic Hot Water 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.

3.6 Information Display

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

Repressurising System & ‘Service Due’

4.1 Central Heating System Pressure

1. The water pressure in the central heating system is indicated by the pressure gauge and also can be viewed on the display when there is power to the boiler.

2. 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 different reading to the display) .

3. 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 1.5 (Fig. 1).

4. A pressure of 3 or greater indicates a fault (E117 displayed). The safety pressure relief valve will operate, at a pressure of 3 (Fig. 3). It is important that your Installer or Service Engineer is

contacted as soon as possible.

5. 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. 2). Error Code E118 will be shown on the display.

4.2 To Re-Pressurise the System

(Using Temporary Filling Loop)

1. It may be necessary to repressurise the system occasionally (when the water pressure falls below 0.7 bar). A filling device (filling loop) will be fitted on the system. This may be on the boiler itself or on pipework near to the boiler. Seek advice from your installer.

2. If the water pressure requires regular re-pressurising a fault or leak is indicated (see section 4.1). Seek advice from your installer.

3. The filling loop will consist of two isolating taps and a separate temporary filling pipe with connection fittings.

4. Fit the temporary filling pipe, and tighten the two nuts on the pipe to the taps.

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

6. When the needle on the pressure gauge indicates between 1 and 2 bar, turn both taps off.

7. The temporary filling loop pipe must be disconnected and completely removed after the system is pressurised. (Ensure the two isolating taps are in the OFF position before disconnecting.) Keep the pipe in a safe place.

4.3 ‘Service Due’ Message (Fig. 3)

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 Baxi Customer Support on 0344 871 1545 to arrange your Annual Service.

5.0 Clearances

5.1 For your Safety

1. This appliance must have been installed in accordance with the manufacturer’s instructions and the regulations in force.

2. Any modification that may interfere with the normal operation of the appliance without express written permission from the manufacturer or his agent could invalidate the appliance warranty. In GB this could also infringe the Gas Safety (Installation and Use) Regulations.

3. Your boiler must not be operated without the casing correctly fitted.

4. Do not interfere with any sealed components on this boiler.

5. Take note of any warning labels on your boiler.

6. Your boiler should have the following minimum clearances for Safety and Maintenance (Figs. 4 & 5):-

Top - 175mm Bottom - 170mm* Left side - 5mm Right Side - 5mm Front - 5mm (In Operation)

- 450mm (For Servicing)

*This is MINIMUM recommended dimension. Greater clearance will aid installation and maintenance.

7. If your boiler is installed in a compartment, do not use it for storage purposes. Do not obstruct any purpose provided ventilation openings.

8. Flammable materials must not be stored in close proximity to your boiler.

9. Avoid skin contact when your boiler is in operation, as some surfaces may get hot e.g. pipework.

10. Ensure that the flue terminal, outside the house, does not become damaged or obstructed, particularly by foliage.

11. It is important that the condensate drain system is not blocked, modified or damaged in any way as this would affect the operation of your boiler. Your installer should have insulated any exposed pipework.
