General Design Considerations
The cupboard footprint needs to be at least 650 mm square. The base chosen for the cylinder should be level and capable of supporting the weight of the unit when full of water as shown in General Data. The discharge pipework for the safety valves must have a minimum fall of 1 : 200 from the unit to a safe discharge point. All exposed pipework and fittings on the cylinder should be insulated, and the unit should NOT be installed in a location where the contents could freeze.
In new systems, pipes should be insulated to comply with building regs, the maximum permissible heat loss is indicated in the table below, and labelled accordingly as follows: i. Primary circulation pipes for domestic hot water circuits should be insulated through their
length, subject only to practical constraints imposed by the need to penetrate joists and other structural elements. ii. All pipes connected to hot water storage vessels, including the vent pipe, should be insulated for at least 1 metre from their points of connection to the cylinder (or they should be insulated up to the point where they become concealed).
In replacement systems, whenever a boiler or hot water storage vessel is replaced in an existing system, any pipes that are exposed as part of the work or are otherwise accessible should be insulated as recommended for new systems, or to some lesser standard where practical constraints dictate.
The pipe connecting the boiler flow to the appliance must not be less than 22 mm copper or equivalent.

Mains Water Supply
Existing properties with a 15 mm supply will be satisfactory, provided the local mains pressure is good, but should be confined to single bathroom properties. For new properties where simultaneous demand is required to more than one bathroom or a bathroom and one or more en-suites, the communication and service pipe into the dwelling should be a minimum of 22 mm (usually in the form of a 25 mm MDPE supply).
The optimum performance is achieved if the inlet pressure is 3 bar dynamic. However, the Stainless ES will function with lower inlet pressures, but this will reduce the performance. For optimum performance, 30L per minute incoming mains flow should be present, however the Stainless ES will work at lower flow rates, although performance will be affected.
Normally the Stainless ES provides well in excess of 40 litres/min in most conditions. Flow rates for ALL mains pressure systems are subject to district pressures and system dynamic loss. Particularly on larger properties with more than one bathroom, the pipe sizes should be calculated in accordance with BS EN 806-3:2006 and BS 8558:2011.
Pipe Layout
In all mains pressure installations it is important to remember that the incoming cold supply must be shared between all terminal fittings. It is important that a 22 mm supply is brought to the appliance and a 22 mm take-off is continued at least to the bath. If there are two baths, 28 mm pipework should be considered. One metre of smaller diameter pipework, or flow restrictors, should be provided on the final connection to all outlets so as to balance the water available. In any event the distribution pipework should generally be in accordance with BS EN806-1 to 5.
Plastic Pipework
This appliance is suitable for use with plastic pipework as long as the material is recommended for the purpose by the manufacturer and is installed fully in accordance with their recommendations.
Secondary Hot Water Circulation
Some models are fitted with a secondary return tapping as standard. If fitted, an extra expansion vessel may be necessary. A non-return valve MUST be FITTED near the return connection. No valve or terminal fitting should be installed between the non return valve and the cylinder. (See schematic arrangement on page 13.) All pipes kept hot by the secondary circulation should be insulated.

Page 9

Installation

Pressure & Temperature/expansion Relief Valve Pipework
The relief valve should be installed to discharge in accordance with G3 of the Approved Document of the Building Regulations and should be piped to where it is visible, but will not cause danger to persons or damage to materials.
The following information is taken from Approved Document G3 of the Building Regulations and is provided to assist with the design and installation of the discharge pipework. However, the information is not exhaustive and reference should always be made to Approved Document G3 of the Building Regulations. The final decision regarding any arrangements rests with Building Control and it is recommended that their advice is sought if you have any concerns regarding this aspect of the installation.
The two safety valves will only discharge water under fault conditions. When operating normally water will not be discharged.
The tundish should be vertical, located in the same space as the unvented hot water storage system and be fitted as close as possible and within 600 mm of the safety device e.g. the temperature relief valve.

Installation

Page 10

The discharge pipe (D2) from the tundish should terminate in a safe place where there is no risk to persons in the vicinity of the discharge, be of metal and:
a) Be at least one pipe size larger than the nominal outlet size of the safety device unless its total equivalent hydraulic resistance exceeds that of a straight pipe 9 m long i.e. discharge pipes between 9 m and 18 m equivalent resistance length should be at least two sizes larger than the nominal outlet size of the safety device, between 18 and 27 m at least 3 sizes larger, and so on. Bends must be taken into account in calculating the flow resistance. Refer to the table and the worked example.
An alternative approach for sizing discharge pipes would be to follow BS EN 806-2:2005 Specification for design installation, testing and maintenance of services supplying water for domestic use within buildings and their curtilages.

Worked Example
The example below is for G1/2 temperature relief valve with a discharge pipe (D2) having 4 elbows and length of 7 m from the tundish to the point of discharge.
From the table below:
· Maximum resistance allowed for a straight length of 22 mm copper discharge pipe (D2) from a G1/2 temperature relief valve is: 9 m subtract the resistance for 4 x 22 mm elbows at 0.8 m each = 3.2 m.
· Therefore the maximum permitted length equates to: 5.8 m. · 5.8m is less than the actual length of 7m therefore calculate the next largest size. · Maximum resistance allowed for a straight length of 28 mm pipe (D2) from a G1/2
temperature relief valve equates to: 14 m. · As the actual length is 7 m, a 28 mm (D2) copper pipe will be satisfactory.

Installation

b) Have a vertical section of pipe at least 300 mm long, below the tundish before any elbows or bends in the pipe work.
c) Be installed with a continuous fall.
d) It is preferable for the discharge to be visible at both the tundish and the final point of discharge but where this is not possible or practically difficult there should be clear visibility at one or other of these locations. Examples of acceptable discharge arrangements are:
1. Ideally below the fixed grating and above the water seal in a trapped gulley.
2. Downward discharges at a low level; i.e. up to 100 mm above external surfaces such as car parks, hard standings, grassed areas etc are acceptable providing that where children play or otherwise come into contact with discharges, a wire cage or similar guard is positioned to prevent contact whilst maintaining visibility.
3. Discharges at a high level; e.g. into metal hopper and metal down pipe with the end of the discharge pipe clearly visible (tundish visible or not) or onto a roof capable of withstanding high temperature discharges of water and 3 m from any plastic guttering systems that would collect such discharges.
4. Where a single pipe serves a number of discharges, such as in blocks of flats, the number served should be limited to not more than 6 systems so that any installation can be traced reasonably easily. The single common discharge pipe should be at least one pipe size larger than the largest individual discharge pipe to be connected. If unvented hot water storage systems are installed where discharges from safety devices may not be apparent i.e. in dwellings occupied by blind, infirm or disabled people, consideration should be given to the installation of an electronically operated device to warn when discharge takes place.

Combines elements 1, 2 and 3 below.
1. Pressure Reducing Valve - This must be fixed near the cylinder. The cold water supply to any mixer taps/showers must be taken from the cold water tapping of this valve to ensure balanced hot and cold pressures. This valve is factory set to ensure the correct operating pressure for the Stainless ES.
2. Non Return Valve - This is integral with the pressure reducing valve to prevent backflow of hot water towards cold water draw off points.
3. Cold Water Expansion Relief Valve - This safety device is preset at the factory and will relieve excess cold water pressure resulting from a fault condition.
There must be no valve on the pipe work between the expansion cylinders and the unvented cylinder which could prevent the expansion of the water contained in the unvented cylinder reaching the expansion cylinders.

Page 13

Installation

Pressure & Temperature Relief Valve
This safety device is also pre-set at the factory and relieves before the temperature reaches 100 °C. It is also a Pressure Relief Valve, and is pre-set to 6 bar.
Immersion Heaters
The immersion heaters fitted to our units are 3 kW 240V ~AC. Check that the mains supply conforms to this, and all external wiring conforms to the most recent revision of the IEE wiring regulations. An Incoloy element is used on this product for standard domestic use and water conditions, use our Titanium elements in all other circumstances, part number SH002.
The immersion heater is fitted into the hot water cylinder using an O-ring. After the unit is filled with water check for leaks to determine if the O-ring has sealed and tighten carefully using the appropriate tool. To prevent damage to the O-ring do not use excessive force to tighten the immersion heater.

Installation

Page 14

The immersion heater is supplied with a thermostat which has been tested for operation in the cylinder and complies with the European directives for Electromagnetic compatibility and radio interference. It is Rated at 20 Amp 250 V ~AC.
The immersion thermostat has two terminals A and B. The Live (brown) wire should be connected to terminal A and the Neutral (blue) wire should be connected to terminal B. It has been our experience that Crimp terminals make better connections. The immersion heater must be fully earthed (earth post) and connected via a double pole isolator switch having a contact separation at least 3 mm, see diagram opposite.
Danger of electrocution: before making any adjustments to the thermostat isolate the immersion heater from the mains electricity supply at the fuse spur unit.
The immersion heater thermostats incorporate a manual reset safety/overheat cut out thermostat. Should this operate, investigate the cause for the operation cut out before pressing the red reset button labelled safety. If there is no apparent fault adjust the control setting down slightly to prevent nuisance tripping.
The direct cylinder is intended to be heated from an off peak supply using the lowest immersion heater(s) and boosted via the upper immersion heater from an on peak supply. Suitable controllers are available to control this operation effectively.

Installation

Connections can come loose in transit, and all should be checked after first fill of the unit.
The control thermostat of the immersion heaters for direct heating of our cylinders are set at 62 °C. The control thermostat for indirect heat exchanger heat up of our cylinders are usually set at between 60 °C - 65 °C. During commissioning the actual temperature that the cylinder reaches when the thermostat(s) operate should be tested and adjusted so that it achieves a minimum of 60 °C. This temperature needs to be achieved on a regular basis in order to comply with the Legionella pasteurisation requirements.
Check the pressure on the air side of the expansion vessel = 3 bar. This must be done when the water in the cylinder is free to expand in atmospheric pressure or the cylinder and relevant pipe work is empty.
Check that all the drain cocks are closed, and open all the cold and hot water taps and other terminal fittings. Allow the system to fill with water, and to run until there is no air left in the system. Close the taps and inspect the system closely for leaks.
Manually open the Relief Valves one by one and check that water is discharged and run freely through the tundish and out at the discharge point. The pipework should accept full bore discharge without overflowing at the tundish, and the valve should seat satisfactorily.
In line with good plumbing practice, use with excessive flux should be avoided. When soldering above the cylinder, ensure flux/solder does not contaminate the cylinder below, since this can cause corrosion. Flushing should be performed as per BS EN 806:4 2010 section 6.2.
Allow the cylinder to heat to normal working temperature, then thoroughly flush the domestic hot and cold water pipework through each tap.
NOTE: If this appliance is to be installed in other than a single domestic dwelling ie. in an apartment block or student flats etc., the hot and cold water system will need to be disinfected in accordance with BS EB 806:4 2010 section 6.3 and the Water Regulations.
Because the Stainless ES appliance is stainless steel, the use of chlorine as the disinfection agent can cause damage unless the appliance is adequately flushed and refilled with the mains water immediately on completion of the disinfection procedure. Damage caused through a failure to do this adequately will not be covered by the warranty. For the reasons mentioned, we recommend the use of a non chlorine based disinfectant such as Fernox LP Sterox as manufactured by Cookson Electronics when carrying out disinfection of systems incorporating these appliances.
Remove the filter from the combination inlet group clean and replace. Refill the system and open all hot taps until there is no air in the pipe work. ENSURE CYLINDER IS DRAINED PRIOR TO CHECKING OR REMOVING FILTER FROM THE COMBINATION INLET GROUP.
Please note a drain valve is not supplied with the cylinder.

IMPORTANT - DRAIN DOWN PROCEDURE
1 Switch off both the boiler and the immersion heater
2 Open the nearest hot tap and run all hot water until cold, then close it
3 Close the incoming cold main at the stop tap
4 Hold open the pressure and temperature relief valve until water stops discharging into the tundish and keep it open
5 Open the cold taps starting from the highest point and working down to the lowest tap, leaving them open
6 When the cold taps have stopped draining, open the hot taps starting from the highest and working down to the lowest tap
7 Open the drain cock and ensure the pressure and temperature relief valve is held open until the cylinder is empty

Allow the cylinder to heat to normal working temperature with whatever heat source is to be used, and check again for leaks. The pressure relief valve or the P&T valve should not operate during the heating cycle. If the P&T valve operates before the pressure relief valve due to high pressure, check that the inlet control group is fitted correctly, and that no valves are fitted between the cylinder and the expansion vessel
The boiler/heating systems should be filled and commissioned in accordance with good practice following the guidance in BS 7593:2006/the boiler manufacturers instructions. This includes adequately flushing the system to remove any debris that may have been introduced during installation/maintenance.
Scale
In hard water areas it is recommended that an in-line scale inhibitor is fitted. Reducing the temperature of the stored water will reduce the rate at which scale forms. If the recovery rate is badly affected, this is an indication that scaling may have occurred. In this event, follow the procedures as recommended by a reputable Water Treatment Company.
NOTE
At the time of commissioning, complete all relevant sections of the Benchmark Checklist located on the inside back pages of this document. This must be completed during commissioning and left with the product to meet the Warranty conditions.

Commissioning

Your Stainless ES unvented cylinder is automatic in normal use, but requires routine maintenance which is normally carried out at least annually along with the boiler service. The maintenance must be carried out by a suitably competent tradesperson who is qualified to work on unvented cylinders. The checks/work needed are listed in the maintenance part of these Instructions.
The control thermostat of the immersion heaters for direct heating of our cylinders are set at 62 °C. The control thermostat for indirect heat exchanger heat up of our cylinders are usually set at between 60 °C - 65 °C. During commissioning the actual temperature that the cylinder reaches when the thermostat(s) operate should be tested and adjusted so that it achieves a minimum of 60 °C. This temperature needs to be achieved on a regular basis in order to comply with the Legionella pasteurisation requirements.
When initially opening the taps, a small surge in flow may be experienced, which disappears as the pressure in the system stabilises. This is quite normal with these types of systems and does not indicate a fault.
In some areas the water will initially appear cloudy, but will quickly clear when left to stand. This is nothing to be concerned about and is due to aeration of the water.
WARNING - If water is seen flowing through the tundish, this indicates a fault condition which needs action.
If the discharge is hot and continuous, turn the boiler and/or the immersion heaters off, but do not turn off the cold water to the appliance until the discharge is cold.
Note: The discharge may stop by itself as the discharge cools.
If the discharge is cold and intermittent, no immediate action is needed but this indicates a problem with the expansion vessel.
However, in both cases you must call the registered installer / a suitably qualified, competent tradesperson, advise them that you have an unvented cylinder and request a maintenance visit.
DO NOT, at any time, tamper in any way with the safety valves or overheat thermostats/wiring.
NOTE
At the time of commissioning, complete all relevant sections of the Benchmark Checklist located on the inside back pages of this document. This must be completed during commissioning and left with the product to meet the Warranty conditions.

User Instructions

Page 20

The Registered Installer is responsible for the safe installation and operation of the system. The installer must also make his customer aware that periodic maintenance of the equipment is essential for safety.
Maintenance periods will vary for many reasons. Gledhill Building Products Ltd recommend a maximum of 12 months to coincide with boiler maintenance. Experience of local water conditions may indicate that more frequent maintenance is desirable, eg, when water is particularly hard, scale-forming or where the water supply contains a high proportion of solids, eg, sand. Maintenance must include, but not limited to, the following:
1. Turn the mains water off, remove and clean the strainer element in in the Pressure Reducing Valve.
2. Manually check the operation of the temperature relief valve. 3. Manually check the operation of the expansion relief valve. 4. Check discharge pipes from temperature and expansion relief valves are free from obstruction
and blockage and are not passing any water. 5. Check that water pressure downstream of combination valve is 3 bar in static condition. 6. Check operation of motorised valve. 7. Check the pressure on the air side of the expansion vessel. This must be done when the
volume in the cylinders is cold. 8. Re-fill the system and ensure that all relief valves have re-seated. 9. Check and advise the householder not to place any clothing or other combustible materials
against or on top of this appliance. 10. On completion of the work, fill in the Benchmark Service Record towards the back of this
manual.
IMPORTANT NOTE
When draining down the appliance for any reason, the instructions provided in the Commissioning Section (Page 19) MUST be followed to prevent potential damage to the cylinder.
After servicing, complete the relevant Service Interval Record section of the Benchmark Checklist located on the inside back pages of this document.

Servicing and Maintenance

General
No water at the tap. Check that the mains water supply is turned ON. Check the line strainer is not blocked. Check that the combination valve has been fitted so that water is flowing in the correct direction.
If the water at the tap is cold, ensure that the boiler has been switched ON and is working correctly. Check that there are no air locks in the primary system. ISOLATE THE UNIT AT THE MAINS ELECTRIC SUPPLY AND THEN CHECK THE FOLLOWING: i. The cylinder thermostat ii. The thermal cut-out, which can be re-set by pushing the red button iii. The motorised valve iv. The boiler thermostat v. The boiler thermostat cut-out (if fitted)
ANY ENERGY CUT-OUT MUST NEVER BE BY-PASSED UNDER ANY CIRCUMSTANCES.
If the units are not getting hot and the heat source is electrical, ensure that the immersion heaters are isolated from the mains before re-setting the energy cut-out. If the immersion heater(s) need replacing this should be done with the units supplied from Gledhill Building Products Limited. Same day despatch by Gledhill Spares to approved installers can be arranged by telephoning 01253 474412.
Discharge From Relief Valves
If cold water is discharging from the expansion relief valve into the tundish check the pressure on the expansion vessel when cold and recharge if necessary.
If the fault continues and the problem cannot be stopped by operating the control a few times then either the Pressure Reducing Valve or the Relief Valve may be at fault. If the cold water pressure is too high, this would suggest that the Pressure Reducing Valve is at fault and the Gledhill approved replacement should be fitted. If the pressure is correct then the Relief Valve will require replacing with a Gledhill approved component.
See Commissioning for drain down procedure.
If there is an overheat fault and very hot water is being discharged, turn off the heat source, but not the water supply.
When the supply is cool, check thermostats and energy cut-outs in the boiler and immersion heaters and replace the faulty component with a unit supplied by Gledhill and check that it works correctly before returning the system to full operation.
