The HE CB25 and HE CB33 are combination boilers providing both central heating and domestic hot water at mains pressure.For maximum hot water temperatures the thermostat should be left at maximum i.e. fully clockwise. If lower temperatures are required, turn the thermostat anti-clockwise. 3. SELECTOR SWITCH This control allows the boiler to provide central heating and hot water or hot water only. Note: The internal clock and frost thermostat will not operate when the switch is in the vertical position, i.e. 'Off' position (0). 4. PRESSURE GAUGE This indicates the central heating system pressure. It should always be within the green band when cold, increasing slightly when hot. If the pressure falls below the green band, i.e. lower red area, refer to the label on the inside of the hinged control panel cover for guidance on re-pressurising the system. Or contact your Installer to have the system checked and pressurised. Note: The bleeding of radiators will cause the pressure to fall and the system will require re-pressurising after doing so. 5. INDICATOR NEONS When neon A (red) and neon B (yellow) are illuminated, the following conditions apply:- Neon B Flashing very slowly (every 5 seconds) - Electricity supply to the boiler is on. B Illuminated continuously - Burner is alight. B Flashing on and off - Temperature sensor fault, contact your Service Engineer. A Flashing on and off - Overheat or flue thermostat has operated. Rotate selector switch to the reset position (3) to reset. If this continues to happen, contact your Service Engineer. A Illuminated continuously - Burner has failed to light. Rotate selector switch to the reset position (3) and the ignition sequence will restart after a delay of about 30 seconds. A and B Flashing on and off at the same time - Blocked flue or fan fault, contact your Service Engineer. A and B Flashing on and off alternately - System pressure is very low and re-pressurisation is required.http://rtuoadzqf.eklablog.com/gitex-exhibitor-manual-a203840070

A Illuminated continuously and B flashing - Pump fault or restricted flow. 6. OVERHEAT THERMOSTAT This thermostat automatically switches the boiler off in the unlikely event of the boiler overheating. When the thermostat operates, the red neon (A) flashes on and off. Rotate the selector switch to the reset position (3) and the boiler will relight. If this continually happens, contact your Service Engineer. 7. PRESSURE RELIEF VALVE If the central heating system overheats and steam or water is discharged from the pipe connected to this valve, turn the boiler off and contact your Service Engineer. Your Installer should have shown you where this pipe terminates, usually outside your dwelling. 8. FROST THERMOSTAT The boiler has a built-in frost thermostat, which automatically operates the boiler if the water temperature falls below 8 C, providing the electrical supply is on and the selector switch is set to position (1) or position (2). Open a hot water tap, the main burner will light and the boiler will provide hot water. Close the tap and the burner will go out. 6. Set the selector switch to position (2) and turn the heating thermostat fully clockwise, refer to Section 3.1. The main burner will light and the boiler will provide central heating. 7. Set the boiler thermostats, clock, external controls i.e. room thermostat to your chosen settings and the boiler is ready to operate. To turn the central heating off i.e. in Summer:- Set the selector switch to position (1). To turn the boiler off for short periods:- Set the selector switch to position (1). Note: In this position the pump will automatically operate for 5 minutes in every 24 hours. If the water temperature falls below 8 C the built-in frost thermostat will operate the boiler automatically until the temperature of the water in the heating system has been raised. To turn the boiler off for longer periods:- Switch off the electrical supply to the boiler. If required, all supplies i.e.http://hardweafocu.eklablog.com/gitzo-gt1541t-manual-a203840072

gas, water and electricity may be turned off at the mains. If there is any possibility of the boiler being left during frost conditions, then the boiler and system should be drained and a label attached to the boiler drawing attention that the system has been drained. If this is required, contact your Service Engineer. 5 BOILER OPERATION The operating sequence of the boiler is controlled by the selector switch on the control panel. Such an interruption in the central heating should not generally be noticed by any reduction in room temperature. Hot water will always be available when a tap is opened. If a two channel clock is fitted to the HE SY25 boiler it will control the operating times of the central heating and hot water. When the selector is set to position (2), it will respond to a demand for heat in the following sequence:- a. The pump will start, the fan will operate at full speed and the main burner will light. b. The output of the burner is automatically controlled to suit the system demand. c. When the temperature of the system water in the boiler reaches that set by the thermostat or the room thermostat is satisfied, the main burner is turned off and the fan stops after 20 seconds. Fully opening a hot tap may not always provide the maximum temperature as the flow rate may be too high, try closing it slightly until the maximum temperature is achieved. The shower should then maintain a relatively constant temperature. Manual bath mixer type shower - When using this type of shower set the boiler domestic hot water thermostat to setting 7, This should avoid excessive temperatures at the shower. Note: If you get unacceptable temperature variations with this type of shower, then a thermostatic or pressure equalising type should be used. 8 IMPORTANT NOTES 1.

BOILER LOCATION Always ensure the following clearances are available around the casing of the boiler:- Top: 220 mm, Bottom: 250 mm, Each side: 5 mm, Front: 450 mm Do not store any other articles in the cupboard containing the boiler and never place any clothing or combustible material on or near the boiler or flue pipe. 2. FLUE TERMINAL The terminal on the outside wall must not be allowed to be obstructed. If it is damaged, in any way, turn the boiler off and contact your Service Engineer. Note: The Alpha HE boilers are high efficiency boilers and when operating vapour will be emitted from the terminal. This is safe and quite normal. 3. MAINS FAILURE In the event of an electrical supply failure the boiler will not operate. When the supply is restored, the boiler will return to normal operation. Remember to reset the clock when the supply is restored.Contact your plumbing merchant or installer for advice when considering purchasing such items. 5. CLEANING Use only a damp cloth and mild detergent to clean the boiler outer casing. Do not use abrasive cleaners. 6. SERVICING To maintain efficient and safe operation of your boiler, routine annual servicing is essential. For advice on servicing contact:- The Alpha Helpline: GAS LEAK If a fault or gas leak is suspected, turn off the gas supply. Do not touch any electrical switches, do not smoke and extinguish all naked flames. To connect a plug:- The colour of the wires in the mains lead of the boiler may not correspond with the coloured markings identifying the terminals in your plug. In this case proceed as follows:- The wire coloured green and yellow must be connected to the terminal in the plug that is marked with the letter E, or by the earth symbol, or coloured green or green and yellow. The blue wire must be connected to the terminal which is marked with either the letter N or coloured black. The brown wire must be connected to the terminal which is marked with the letter L or coloured red.

Failure to install or service appliances correctly could lead to prosecution. The Benchmark Checklist must be fully completed by the installer on installation and commissioning of the boiler. The Benchmark Checklist is shown in Section 12, page 43, of the Installation and Servicing instructions. All CORGI registered installers carry a CORGI ID card and have a registration number. Both should be recorded in the Checklist.Pull the controls panel cover forward and down to gain access to the controls.Nepicar House, London Road, Wrotham Heath, Sevenoaks, Kent TN15 7RS Tel: These instructions have been carefully prepared but we reserve the right to alter the specification at any time in the interest of product improvement.Response: The fit anywhere combi It has been designed to be Gas Fired Wall Mounted Combination Boiler User s Operating Instructions Natural For installation guide see reverse of book For installation guide see reverse of book Gas Fired Wall Mounted Combination Boiler Heatmax Combi HE Range.

The boiler does not require any special air vents for cooling purposes located in the room in which it is installed or when installed in a cupboard or compartment. However minimum clearances must be kept for servicing purposes. Your model needs to be installed on a flat vertical wall which is capable of supporting the weight of the boiler. The boiler can be fitted to or adjacent to a wall comprising of a combustible material without the need for a special thermal insulation barrier. The Alpha Innovation boilers can be installed in any room or internal space when following IEE Wiring (BS7671) Regulations. Also most of the boilers are capable of fitting into a cupboard or compartment.Where water pressure at mains exceeds 7 bar a pressure reducing valve should be installed A supply of direct mains fed hot and cold water is permitted provided the appliance is of the over-rim flushing type. Indicator neons should be used for basic fault finding If fault recurs this indicates an overheat condition. The boiler should be turned off and your installer contacted. 2. Replace primary temperature sensor fault 3. Replace DHW sensor When set to, the boiler will only operate in the Domestic Hot Water mode. When set to, it will operate in the Domestic Hot Water and Central Heating mode. DHW is capable of constantly controlling hot water domestic system. The whole boilers operation is designed to provide priority to domestic hot water supply over the central heating. If a demand for hot water is required during a central heating period, the boiler will automatically switch to the hot water mode until the demand is satisfied. This interruption in the central heating is only when the demand for hot water is present. At this time and when air pressure switch will light the burner, fan will start to run at its full speed. The burner is suppose to adjust to provide the system demand.

At the point when the temperature of the water reaches the set temperature burner output will be reduced accordingly. The moment that demanded temperature is reached, burner will switch off. Normally fan would continue to run for 20-30 more seconds, and then minimum 3 minutes will pass bufore burner is allowed to re-light. Approximately 3 minute interval is used for reducing residual heat that boiler produced. Whenever the CH (central heating) sensor did not recognize the pre-set temperature, and the thermostat shows the right level the burner will be turned off. In this case fan will continue to run for about 20 seconds and then the pump will run for another 30-40 seconds. In those cases there is no 3 minute off interval before re-lighting the burner. Whenever the is a need for DHW (domestic hot water) during the 3 minute interval, the boiler will provide hot water till the tap is closed. After tap is closed the boiler will immediately change back to providing CH. Burner output is being set by temperature selected by user. Whenever the is no water flow recognized by the flow switch,burner will turn off and the boiler immediately goes back to the central heating mode. When the burner is turned off, the fan will continue to run for 20 seconds if the selector is set for hot water only. Wait till the boiler cools down. Take a note of what fuel is suppose to be used (label on the inside of case side panel). You need to pay special attention to: Allow the boiler to cool. Remove front panel from the boiler as shown on the picture below. In some instances you will need to remove side panels by first unfixing bottom screws and only then lifting it upwards and forwards. Look at the picture below While replacing the cover, pay attention to secure all existing wiring.To properly drain the boiler follow steps below Allow the boiler to cool. Open the drain point. Open any hot tap below the level of the boiler to allow as much draining as possible.

It only takes a minute to sign up. Yesterday I removed a radiator for cleaning then put it back on and re-pressurised the system. It was working ok last night. Reading the troubleshooting bit in the servicing manual points to section K on page 41 but that doesn't mean a lot to me I've tried resetting the boiler. I've tried powering off and then on again after various lengths of time 5seconds - 30minutes. Nothing has stopped the lights flashing and boiler to reactivate. In the proper order?

When it powers back on it goes straight into the error state. This introduces air into the system. Section 5.1 of the manual indicates a very clear sequence of steps that should be followed to re-pressurize the system, one very important one of which is bleeding (venting) the radiators, one by one, from lowest to highest. Air is compressible, water is not, so having air in the lines will mess with pressure readings something nasty. Removing and cleaning may well resolve your issue.

If the pressure of your boiler has dropped, you may need to re-pressurise it to ensure your boiler continues to heat your home and provide hot water effectively. You can check the pressure of your boiler and re-pressurise it yourself without having to call an engineer out. This post explains everything you need to know when it comes to re-pressurising a boiler and how to do it. How do I check my boiler pressure. You can check the pressure of your boiler by looking at the gauge on the front when your boiler is off and cool. A hydraulic pressure gauge will indicate the standard operating pressure with a green zone and the maximum safe operating pressures with a red zone. Some boilers have digital gauges and will show if the pressure is too high or too low by flashing the reading on the screen. What pressure should combi boilers run at. The pressure of your combi boiler should be between 1 and 1.5 bar. If your pressure reads at less than 1 bar, it’s possible that you have lost water from the system via a leak. If the pressure reads at 2.75 bar or above, you may need to bleed a radiator to release the pressure and bring it back down to a suitable level. If you attempt to bleed a radiator, you should make sure that you have a way of catching the water to prevent the walls or floor from being ruined. Take caution when undertaking this job as the water can be very hot. If you’re unsure about anything, it’s a good idea to call an engineer who can help you. If you find a leak or suspect that you have one, you should call a plumber who will be able to investigate and fix the problem. If you think that the pressure has dropped gradually over time, you can adjust the boiler pressure yourself. How do I re-pressurise my boiler. Before getting stuck in, it’s a good idea to check your boiler manual for instructions on how to re-pressurise your combi boiler and whether you can do this yourself. Every type and model of boiler is slightly different so double check you know what to do.

Once you’re ready, you can use the following steps to complete the process: Switch off your boiler and allow it to cool completely Find the filling loop and check that both ends are securely attached. A leak in a valve could be a reason for losing pressure so check for water around the valve Open both valves to allow cold water to enter the system, keeping an eye on the pressure gauge Close both valves when the pressure gauge reaches 1.5 bar Remove the filling loop if it isn’t a built-in one Turn the boiler back on and recheck the pressure There are two types of filling loop: external and built-in. An external one will need to be attached by you, so you should attach it during Step 2 and then remove it before turning the boiler back on in Step 6. By re-pressurising your boiler, you’re allowing more water to enter the system from the mains supply. If you accidentally over-pressurise the system, don’t panic. You may need to bleed your radiators to bring the pressure back down. You should keep an eye on the pressure over the following days and weeks to make sure the pressure doesn’t drop again. If it does, there’s a chance you may have a leak. If you get stuck while trying to re-pressurise your Viessmann boiler, you can always contact us for support. Get your free consultation on a new heating system. Get started How often should you re-pressurise a combi boiler. There isn’t a specific timeframe that states when you should re-pressurise your combi boiler. You should re-pressurise it when the pressure has dropped to below 1 bar. This indicates that water has been lost from the system and needs to be replaced. You shouldn’t need to do this frequently. If you’re doing it more often than you think you should be, contact your installer as your boiler could be leaking. How long does it take to re-pressurise a boiler. Depending on how low the pressure of your boiler is, you should allow water in through the valves for around 10 seconds.
