3.1 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 (Fig. 1).

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

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

3.2 To Re-Pressurise the System

(Optional Filling Loop)

1. The procedure is for the optional filling loop kit when fitted. However, even if your boiler has an external loop, the principle is similar.

2. Look at the boiler from underneath. There will be two taps at the end of copper pipes, one with a blanking cap on the end. Do not operate these taps yet.

3. Your installer will have left a metal braided hose (the ‘filling loop’) with you for safe keeping.

4. This loop MUST be connected to the taps. Remove the blanking cap and set aside.

5. Connect the loop to the taps with the wing nuts. These should be hand tightened.

6. Carefully open the handles on both taps and check the boiler pressure gauge. Once the needle on the gauge is above the 0.5 mark both taps can be closed.

7. Undo the two wing nuts, remove the loop and refit the blanking cap. Put the loop in a safe place for future use.

4.1 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 (Fig. 4):-

Top - 200mm Bottom - 150mm Left side - 5mm Right Side - 5mm Front - 5mm (In Operation)

- 450mm (For Servicing)

*This is the MINIMUM recommended dimension. Greater clearance than this 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.

GB - Heating Industry definition meaning England, Scotland, Wales, Northern Ireland, Isle of Man and the Channel Isles

5.0 Care of the Boiler

5.1 Cleaning the Outer case

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

CLEANING AGENTS.

5.2 Protection & Precaution

1. The boiler incorporates an integral frost protection feature that will operate in both modes. If the boiler temperature falls below 5° C, then the boiler will operate until the water temperature has been raised.

2. If a system frost thermostat has been fitted (your installer will be able to advise you), then to operate correctly and protect your system, the gas and electricity must be left on and the appliance set in the central heating mode.

3. The boiler incorporates an integral pump protection feature which continually monitors the time since the pump last operated. To prevent seizure, the pump will operate for approximately 1 minute if it has not run in the last 24 hours.

5.3 Fault Indication

1. If a fault occurs on the boiler an error code may be shown on the facia display (Fig. 5).

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.
