3.0 Repressurising System

bar

3.1 Central Heating System Pressure

1. The normal operating water pressure is when the needle is in the GREEN section of the gauge, between 1 and 2.5 bar (Fig. 1). If the pressure exceeds 3 bar (needle in the RED section) the safety pressure valve will operate and a fault is indicated. Contact your installer.

2. It may be necessary to repressurise the system occasionally (Fig. 2). The needle will be in the lower RED section of the gauge, between 0 and 0.5.

3. A filling device (the filling loop) will be fitted on the system. This will be on the boiler itself (Fig. 3), or on pipework near to the boiler.

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

5. The filling loop consists of two taps and a separate flexible pipe with connection fittings.

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

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

8. When the needle on the gauge is indicating 1 or more, in the green section of the gauge, turn both taps off.

9. Disconnect the flexible 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.

4.0 ‘Intelligent Pre-heat’ Feature

Operation of Pre-heat

1. The boiler incorporates an intelligent pre-heat feature that will ensure optimum domestic hot water performance.

2. This features ‘learns’ the domestic hot water demand, and pre-heats the boiler primary circuit (main heat exchanger, pipework within the boiler case and domestic hot water heat exchanger) in anticipation of further demand at the same time on the next day.

3. The feature works on a 24 hour basis. If for example there is a demand for hot water at 7:00 AM on Monday, the pre-heat will operate at 6:50 AM on Tuesday for 1 hour. Similarly if there is a demand at 9:25 PM, the preheat will operate at 9:15 PM the next day, again for 1 hour.

4. If on Tuesday at 7:00 AM there is no hot water demand there will be no pre-heat on Wednesday at this time.

5. The feature also operates for one hour after each demand to maintain the temperature of the boiler.

6. There can be up to 24 pre-heat operations in a 24 hour period. While operating in the pre-heat mode the boiler will fire up briefly 3 or 4 times in the hour to maintain the boiler at temperature.

7. During the pre-heat period the domestic hot water indicator will flash (Fig. 6).

8. The pre-heat feature will not operate if the DHW Temperature Control is turned fully anticlockwise (Fig. 4). In this position the boiler will operate as a conventional combination boiler, providing hot water at 50° C.

9. Once the Temperature Control is turned approximately 30° clockwise (Fig. 5) the pre-heat feature is activated.

10. Between 30° and fully clockwise the hot water temperature can be altered from 40° and 60° C.

5.1 For your Safety

NOTE: Only qualified persons are authorised to

assemble, install and maintain the installation.

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. 7 & 8):-

Top - 200mm

(300mm for 80/125mm flueing system) Bottom - 200mm Left side - 5mm Right Side - 5mm Front - 5mm (In Operation)

- 450mm (For Servicing)

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.

6.0 Care of the Boiler

6.1 Cleaning the Outer case

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

CLEANING AGENTS.

6.2 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.

6.3 Fault Indication

1. If a fault occurs on the boiler an error code may be shown on the facia display (Fig. 9).

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 & E160 indicate faulty components. You should make a note of the displayed error code and contact your installer or service engineer.

4. If E110 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.

In an Emergency

If a water or gas leak occurs or is suspected, the boiler can be isolated at the inlet valves as follows;

1. Using a suitable open ended spanner, turn the square nut on the gas tap through 90° (1/4turn) to isolate the gas supply at the boiler (Fig. 10).

2. The water isolating valves are positioned under the boiler and can be closed by turning their taps to the right towards the wall (Fig. 10).

3. Call your Installer or Service Engineer as soon as possible.

If you smell gas

Do not operate light switches Do not operate any electrical equipment Do not use a telephone in the hazardous area Extinguish any naked flame and do not smoke Open windows and doors in the hazardous area Turn off the gas supply at the meter Warn any other occupants and vacate the premises Telephone the National Gas Emergency Service on:0800 111 999
