The Greenstar Highflow CDi condensing combi boiler series

The Greenstar Highflow CDi series is part of a market leading range of energy-saving condensing floor standing gas-fired combi boilers.

Higher efficiency therefore highly cost effective

All of the new Greenstar Highflow CDi condensing combi boilers are SEDBUK A rated. This means they have an average annual efficiency of 90.8%, standard efficiency boilers achieve around 78% efficiency. Therefore by upgrading to a Greenstar Highflow CDi boiler, consumers can reduce their gas bills as well as their carbon footprint.

The Greenstar Highflow CDi condensing boiler series delivers this energy-saving performance by recycling exhaust gases to extract the latent heat – a highly efficient use of energy which also significantly reduces carbon dioxide emissions into the atmosphere.

To all these major benefits you can add yet more: renowned

Worcester quality and reliability; outputs and flow rates to comfortably satisfy the heating and hot water demands of the larger household and all-round value for money.

The Greenstar Highflow CDi condensing combi boiler series

A condensing boiler is more efficient due to its ability to extract more heat from the flue gases normally lost to the environment through the flue system.

Modulating central heating and hot water outputs combined with separate consumer controls, also mean that comfortable temperature levels for both can be set independently of each other.

Greenstar Highflow CDi combis use a proven aluminiumsilicon heat cell with an extra large surface area.

As the flue gases pass through the heat exchanger this extra surface area cools the flue gases to around 55°C at which point the latent heat within is released. This is heat that would normally be lost to the atmosphere.

Greenstar Highflow CDi combis are supplied as standard suitable for sealed primary water systems. The appliance contains a 12 litre expansion vessel, 3bar pressure relief valve, pressure gauge and an automatic air vent. The appliance cannot be used on an open vent system.

It is this ability to extract as much heat as possible from the gas it burns that gives Greenstar Highflow CDi combis an exceptionally high level of operating efficiency.

This higher efficiency is recognised within section L of the

Building Regulations, subsequently achieving a higher SAP or NHER rating.

The separate plated DHW heat exchanger combined with the thermal store ensures that hot water is delivered instantly to the outlet being operated.

Fluing

Greenstar Highflow CDi combis are available as a multidirectional room-sealed fanned flue appliance.

Gas

The Greenstar Highflow CDi is manufactured in both natural gas and Liquid Petroleum Gas (LPG) variants.

The advantages of a combi boiler

A combi (or combination boiler) is a compact and highly efficient unit giving all the heating and hot water you need, with significant savings on running and installation costs.

So you not only save space, but also reduce hot water costs

– which can account for up to 60% of a typical domestic fuel bill.

Unlike a conventional heating and hot water system, a combi boiler system does not store domestic hot water. It heats water directly from the cold water mains – as you use it. There’s no hot water cylinder, no tank in the loft (and so less risk of freezing and flooding), and none of the connecting pipework.

A combi also supplies hot water at mains pressure, giving you powerful showering without the need for a pump. And as, on average, a shower uses considerably less water than a typical bath, the savings on hot water costs and water consumption can be significant.

Operation

Hot water mode

With the appliance in a standby condition, i.e. thermal store or heatbank at temperature set by the hot water thermostat, a demand for hot water will cause the flow turbine to energise the pump and circulate primary hot water around the boiler and the plated water to water heat exchanger. The burner will ramp-up at its maximum setting and modulate accordingly to maintain the temperature of the heatbank.

• Worcester Greenstar Highflow CDi combis can be sited underneath a worktop as servicing can be undertaken from the front. A removable section of worktop is recommended should you require top access for maintenance work

On a demand for central heating the pump will energise, the diverter valve will open and primary water will circulate around the heating system. The burner will light at the minimum setting and ramp upwards to meet the system demand. The radiators will heat up to the temperature set by the fascia mounted heating temperature controller

(assuming there are no TRVs on the radiators).

Optional plug-in controls

Greenstar Highflow CDi floor standing condensing combi boilers are available with a range of easy-to-use controls. These fascia-mounted controls offer simple plug-in connection to the boiler circuit board.

Mechanical timers

MT10 mechanical timer

The simplest Worcester control device – an easy-to-use analogue clock for setting heating time periods. It plugs into the boiler fascia via a pre-prepared plug and socket.

8

MT10RF mechanical RF thermostat

Has an analogue display for setting night and day time periods and temperature. The receiver plugs into the boiler and is activated remotely by the RF (radio frequency) controller, which requires no wiring. So installation is clean and simple – no disturbance to floorboards or carpets. Nor is there any need for a separate room thermostat.

These mechanical timers do not control domestic hot water pre-heat. If this function is required please select a digital programmer. Alternatively, an additional single channel timer for hot water control, could be wired in remotely.

Digital and wireless programmers and room thermostats

DT20RF digital RF thermostat with twin channel programmer

Installing the Greenstar Highflow

CDi series

Siting of appliance Site preparation/portability

General

The appliance is not suitable for external installation. The floor on which the boiler is to be mounted should be capable of supporting an overall weight of approximately

160kg.

Greenstar Highflow CDi appliances are supplied with a floor mounted pre-plumbing jig. The jig enables all gas and water services to be pre-plumbed and tested prior to fitting the boiler.

Clearances

The following clearances should be allowed for installation and servicing.

For ease of installation the appliance has a roll-in boiler tray which allows it to be rolled into place once the connections have been made.

Condensate disposal

All condensing boilers generate condensate discharge which needs to be piped away from the appliance using a plastic pipe.

Never terminate or discharge into any open source, including: sink, bath, shower, bidet, toilet etc.

Note: any external condensate pipework should be protected with weather resistant insulation to help prevent freezing.

The amount of condensate generated depends on the efficiency and operating status of the appliance. Depending on operating temperatures, the appliance will condense in both heating and hot water modes and may generate up to 2.7 litres of condensate per hour for the 440CDi and

3.7 litres per hour for the 550CDi.

The condensate connection on Worcester appliances is in

22mm polypropylene. The pipe should be extended and run away from the appliance with a constant fall of 3º or at least 50mm in every metre away from the boiler.

The condensate pipe can terminate into any one of four areas (see next page).

Condensate termination and route

Greenstar Highflow CDi combis incorporate a condensate pump which allows condensate to be plumbed above the boiler, allowing more flexible siting possibilities.

Whilst all of the methods are acceptable it is best practise to terminate the condensate pipe via an internal waste system. This will eliminate the need for any external condensate pipe runs which can be susceptible to freezing in extreme weather. Best practise is not to run external condensate pipe any further than 3m. If it is necessary to run more than 3m externally increase pipe size to 32mm.

Condensate connection

The condensate pump fills up and periodically discharges through the flexible condensate pipe between 200mm and

4,500mm from floor level. After this point the condensate continues down the 22mm rigid pipework to the outlet using gravity.

External condensate pipework

The Worcester Greenstar Highflow CDi appliances have a condensate pump rather than a syphonic condensate trap.

Rather than the condensate constantly dripping into the discharge pipe, the condensate is collected in the pump which releases it in 100ml quantities. This will help prevent freezing occurring.

Boiler location and clearances

This boiler is only suitable for installing internally within a property at a suitable location on a fixed, rigid noncombustible surface of at least the same size as the boiler and capable of supporting the boiler weight.

Wherever possible the condensate discharge pipework should be routed and terminated internally. Should this not be possible, and the only available route is external, the following conditions should be observed:

• The pipework length should be kept to a minimum and the route as vertical as possible

• Where pipework could be subjected to extreme cold or wind chill, a weather proof insulation should be used.

Alternatively, the condensate pipework could be increased to a minimum 32mm.

Compartments: Follow the requirements of BS 6798 and

BS 5440 Part 2 and note:

• Minimum clearances must be maintained

• An access door is required to install, service and maintain the boiler and any ancillary equipment

• If fitting the boiler into an airing cupboard use a noncombustible perforated material (maximum hole sizes of

13mm) to separate the boiler from the airing space.

Flue terminal positioning

General position

1. The terminal must not cause an obstruction nor the discharge a nuisance. Particular care should be exercised with regards to the pluming of the flue gases and any increase in noise levels.

2. If a terminal is fitted less than 2 metres above a surface to which people have access, then a guard must be fitted. The terminal guard must be securely fixed to the wall using suitable plugs and corrosion resistant screws. The guard must be symmetrically positioned about the terminal assembly and spaced to allow a gap of 50mm between the end of the terminal and the condense compatible guard.

3. In certain weather conditions, a white plume of condensation will be emitted from the flue terminal and siting where this could be a nuisance, i.e. near security lighting, should be avoided.

4. The air inlet/outlet duct and the terminal of the boiler must not be closer than 25mm to any combustible material. Detailed recommendations on protection of combustible materials are given in BS 5440:1.

The flue system must be installed and terminated in accordance with the recommendations of BS 5440:Part 1.

The following criteria should be noted when planning the installation.

• The concentric flue system must be inclined at 3º

(52mm per metre) from the appliance, to allow condensate to drain back into the boiler.

• Because the appliance operates at high efficiency a white plume of condensation will be emitted from the terminal. Care must be taken when selecting the flue terminal position (see pages 18 - 19).

Installation requirements

Installation of Greenstar Highflow CDi combis must be in accordance with the relevant requirements of the Gas

Safety (Installation Use) Regulations at the time of installation, current IEE Wiring Regulations, local Building

Regulations, Building Standards (Scotland) regulations and bylaws of the local Water company and Health and Safety

Document No. 635 (Electricity at Work Regulations 1989). It should be in accordance with the relevant recommendations of the following British Standards:

BS 6798; BS 5449; BS 5546:1; BS 5440:1; BS 5440:2;

BS 6891.

System filling and make-up

To comply with the Water Authority requirements, the system should be filled via a temporary hose connection to the mains cold water supply, with a double check valve assembly and a test point fitted to the mains water side of the temporary circuit. This is supplied within the boiler.

Valves and joints

It is very important that all valves and joints are able to sustain a working pressure of up to 3bar (45psi). Particular care should be exercised when fitting radiator valves and only those of high quality to BS 2767:10 should be used.

All other valves and fittings should comply with BS 1010.

Gas Safety (Installation and Use) Regulations. All gas appliances must be installed by a Gas Safe registered person in accordance with the above regulations. Failure to install appliances correctly could lead to prosecution.

Loss of water pressure from a sealed system will require continuous recharging with fresh water and consequential introduction of air. Air is highly corrosive and will considerably reduce life expectancy of radiators, pumps etc.

The manufacturers notes must not be taken in any way as overriding statutory regulations.

Sealed primary systems

Worcester Greenstar Highflow CDi combis are supplied complete with all the necessary components to form a sealed primary system. Included are a pre-plumbed expansion vessel (12 litres), a pressure relief valve (set at

3bar), an automatic air vent and a pressure gauge.

Plastic pipework

The use of plastic pipework is acceptable. However, some plastics are permeable to oxygen and must be avoided. Only pipework with a polymeric barrier should be used. Please note that the first 600mm of pipework connected to the boiler must be copper.

Open vented primary systems

It is not permissible to install a Greenstar Highflow CDi combi on an open vent system. The expansion vessel fitted to the appliance will accommodate differing system volumes, depending upon its initial charge pressure, and system pre-pressurisation.

The table below shows the system volume that can be accommodated under different conditions. If it is found that the system volume exceeds that catered for by the expansion vessel fitted within the appliance, then an extra vessel should be added as close to the appliance as possible in the heating return pipe. Refer to BS 5449:1 and BS 6798:1 for further information.

Natural gas supply Electricity supply

Appliances, when on a full output demand, will require up to 3.1m

3 /hr of gas for the 440CDi and 4.4m

3 /hr of gas for the 550CDi. The gas meter and supply pipes must be capable of supplying this quantity of gas in addition to the demand from any other appliance being served. It is important that a gas supply pipe of at least 22mm diameter is used. Under no circumstances should the size of the gas supply pipe be less that of the appliance inlet connection.

The meter outlet should be capable of ensuring a nominal pressure of 20mbar (8in wg) at the appliance. Particular consideration should be given to the resistance to gas flow created by elbows, bends etc. Pipework should be sized to overcome this resistance, details of this are given in the table below.

A 3amp fused three pin plug and unswitched shuttered socket outlet (both complying with BS 1363) or preferably a double pole isolator with a contact separation of 3mm in all poles supplying the appliance should be used.

The appliance electrical circuits are also protected by an internal 2.5amp fuse. The appliance must be earthed.

Mains cold water supply

Water Authority requirement

A direct mains cold water connection is permitted by Water

Authorities, however, it is recommended that reference be made to local requirements. In the event of difficulty contact the Worcester Technical Support Department.

Cold water connection

Wherever possible the cold supply to the appliance should be the first connection off the mains supply, in order to minimise hot water flow reduction when cold water services are operated. The final 600mm of piping to the appliance should be of copper only.

Liquid Petroleum Gas (LPG) supply

An LPG kit is an available accessory for Greenstar Highflow

CDi combis. The appliances, when on a hot water or full output demand, will require up to 2.3kg/hr of gas for the

440CDi and 3.2kg/hr of gas for the 550CDi. The gas tank or bottles must be capable of supplying this quantity of gas at a nominal pressure of 37mbar (14.8in wg) at the appliance.

The table below shows the LPG discharge through varying lengths of pipe and the resistance to flow created by elbows, bends etc. Pipework should be sized so as to overcome this resistance.

Cold water pressure

To achieve the stipulated flow rates of 20l/min (4.4gpm)/

25l/min (5.5gpm) a working cold water mains pressure of

1.5bar/1.7bar is required. The appliance will operate at a minimum working pressure of only 0.5bar (7.5psi) however a reduced hot water flow rate should be expected.

Back-flow prevention devices, including water meters, can prevent the expansion of hot water into the cold water main. However, this can result in a pressure build-up that may cause damage to the boiler and household devices such as showers, washing machines etc. In these cases we recommend that a mini-expansion vessel

(Part No. 7 716 192 105) be fitted adjacent to the boiler in the cold water main.

Hot water supply

As with all mains fed systems, the flow rate of water obtainable from individual taps will vary in relation to the number of taps operating simultaneously, and will depend upon the cold mains supply available to the property.

Therefore, in order to avoid excessive starvation of flow to individual taps, flow balancing may be required by the use of proprietary constant volume flow regulators or

Ball-o-Fix valves.

Use in hard water areas

As the maximum temperature of the domestic hot water heat exchanger is limited by the electronic control circuit, there is normally no need for water treatment to prevent scale accumulation.

In areas where exceptional water conditions prevail, consideration may need to be given to the fitting of a device capable of preventing scale. In such circumstances the advice of the local water authority should be sought.

Hot water systems

Taps and valves

Hot and cold taps and mixing valves used with Greenstar

Highflow CDi appliances must be suitable for operating at a mains pressure of up to 10bar (150psi) and temperatures of 65°C (150°F).

Showers

When a loose head shower with a flexible hose is used over a bath or shower tray, the hose must be fixed so that the head cannot fall closer than 25mm (1in) above the top edge of the spill over level of the relevant bath or shower tray.

Alternatively, the feed pipes to the shower should incorporate a double check valve assembly or a check valve and vacuum breaker.

Worcester Greenstar Highflow CDi appliances are offered with a full 2 year guarantee* on parts and labour, a 10 year warranty* on the primary heat exchanger and a 5 year warranty* on the plate heat exchanger. Ongoing service and maintenance contracts can be arranged through the

Worcester Customer Service Department.

*Subject to conditions.

With fixed head showers no provision is necessary.

Warranty

The use of a thermostatically controlled shower will give added comfort and safeguard against high hot water temperatures.

Bidet

The supply of hot and cold water mains direct to a bidet is permitted provided that the bidet is of the overrim water feed type. The outlet(s) should be shrouded and not have any temporary hand held spray attached. No other anti-syphonage arrangements are necessary.
