General Design Considerations
The cupboard footprint needs to be at least 650mm 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 22mm copper or
equivalent.

the Building Regulations”.

Mains Water Supply
Existing properties with a 15mm 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 22mm (usually in the form of a 25mm
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 22mm supply is brought to the appliance
and a 22mm take-off is continued at least to the bath. If there are two baths, 28mm 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.

It is not acceptable to discharge straight

Trapped gully
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 600mm 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 9m long i.e. discharge
pipes between 9m and 18m equivalent resistance length should be at least two sizes larger
than the nominal outlet size of the safety device, between 18 and 27m 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 7m from the tundish to the point of discharge.
From the table below:
• Maximum resistance allowed for a straight length of 22mm copper discharge pipe (D2)
from a G1/2 temperature relief valve is: 9m subtract the resistance for 4 x 22mm elbows
at 0.8m each = 3.2m.
• Therefore the maximum permitted length equates to: 5.8m.
• 5.8m is less than the actual length of 7m therefore calculate the next largest size.
• Maximum resistance allowed for a straight length of 28mm pipe (D2) from a G1/2
temperature relief valve equates to: 14m.
• As the actual length is 7m, a 28mm (D2) copper pipe will be satisfactory.

Installation
b) Have a vertical section of pipe at least 300mm 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 100mm 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 3m 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 3kW 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.

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 250V ~AC.
The immersion thermostat has two terminals L and N. These should be connected as shown
in the diagram. 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.
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.

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.
Page 21
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.
