Introduction
The ETS is a wall hung electric system boiler with
three models in the range :
-ETS 09 and 15 are available in either single phase
or tri phase.
-ETS 24 is tri phase.
The boiler is equipped with all the necessary
components to allow direct connection to a heating
system without the need for a feed and expansion
cistern. These components include; primary 8 litre
expansion vessel (suitable for a system water
content of up to 128 litres), pressure and
temperature gauge, safety valve, circulating pump,
low water pressure switch, control and high limit
thermostats, on/off and power level switches.
The boiler heat exchanger is constructed from mild
steel with welded joints and is insulated with a glass
wool jacket and with aluminium cover. The steel
casing has a white stove enamelled finish and a grey
control panel.
Immersion heaters, constructed from stainless steel
and mounted in the top of the boiler, provide the
power source for the ETS Boiler. The ETS 09 and
ETS 15 have 6 in total, and the ETS 24 has 10 (9 used
with 1 spare).
The boiler is suitable for connection to most heating
and hot water systems, with a maximum working
pressure of 3bar and a maximum temperature of
85˚C. The ETS can also be used in multiple boiler
installations allowing greater outputs to be achieved.
Electrical connection access is located underneath
the boiler, and connection glands for both the main
power supply and optional external controls are
provided, suitable for single or three phase electrical
supply depending upon boiler output required. An
internal 3 amp MCB is linked to the incoming
electrical supply to provide the internal control
circuit, from which optional controls can be
connected e.g. internal or external timeclock, room
thermostat or Honeywell Sundial controls.
The temperature of the boiler is controlled by a dual
stage thermostat which is set by the user to give the
desired boiler temperature. When the boiler has
heated up to within 7°C of the set temperature, the
thermostat switches off one power stage and
therefore reduces the heat input.
Thanks to this simple but effective form of
modulation, the ETS has longer working cycles and
requires less stops and starts, thus resulting in a
more even temperature across the boiler. It also
means less wear and tear on components and,
importantly it uses less power once it has reached
working temperature.
The ETS Boilers have been manufactured to comply
with the following standards BS EN60335-2-35:
1998, BS EN55014-2:1997 and BS EN50081-1-1:
1992.
MANUAL HANDLING INFORMATION

REMOVING THE BOILER FROM THE PACKAGING
•Before lifting the boiler from the packaging, ensure that the installation area is clear and that there are no
obstacles making installation difficult or unsafe.
•Lay the boiler on its back (as shown on the box side), open the box and remove the cardboard
packaging.
•Remove the polythene cover and the polystyrene corner protection pieces.
•With the boiler still in the box, remove the boiler front cover panel screws “A” as described on page 7.
•Put the front cover panel safely aside to avoid damage.
•With the front cover panel removed, the two panel bottom retaining tabs on the casing can be
seen - these can be sharp and care must be taken when lifting the boiler.
•With help from another person, lift the boiler from the packaging holding the lipped front edges of the
side panels.
•Do not lift or carry the boiler using the top automatic air vent and bottom pump.
The weight of this
boiler is 36Kg, which
could present a risk of
injury.
Care should be taken
when loading and
unloading the boiler to
and from vehicles.
We recommend that
the boiler be handled
by two people until it is
securely fixed to a wall.
The safest route from
the vehicle to the point
of installation should be
carefully assessed
before unloading the
boiler.
Mechanical lifting aids
should be utilised
whenever possible.

User Data
All user controls are situated on the front panel of the
boiler, there are no user controls inside the boiler
casing. The following instructions assume that the
boiler has been commissioned, and that the system is
filled with water and has been fully vented.
Setting Up
•Before switching on any electrical supplies to the
boiler ensure that the combined temperature and
pressure gauge reads at least 1 bar and the control
thermostat is set to the desired temperature.
•If an internal time clock is fitted ensure that this is
switched on (see “Optional Internal Time Clock”)
and if any other auxiliary controls are fitted e.g.
programmer, room thermostats, cylinder thermostats
etc, consult appropriate manufacturers' instructions
to switch these on.
•Switch on any local means of isolation to boiler.
•Switch the boiler on using the ON/OFF switch (the
red neon light on the switch should now glow).
•Turn on both power level switches - after a short
period of time the boiler temperature should start
to rise, indicated by the combined temperature
and pressure gauge. If the boiler fails to operate,
the overheat safety thermostat should be checked.
Access to the thermostat reset button is obtained
by unscrewing (anti-clockwise) the domed button
cover on the front panel (a screwdriver is not
required).The reset button can then be seen - press
the button, a click should be heard and the button
is reset. If no click was heard the device is not at
fault and further investigation is required by a
suitably qualified engineer.
•The internal clock or external programmer can
now be set to allow on/off periods as desired.The
ON/OFF switch and 2 power level switches should
be left in the ON position during normal use.
NOTE : the power level switches will automatically
switch on and off during normal boiler operation,
depending on boiler temperature.
•If the boiler is not in regular daily use during cold
periods, it is recommended that it be fitted with a
frost sensing thermostat to override the timeclock
and prevent the system from freezing.
•As with most boilers and heating appliances the
casing and pipework can get hot during normal
running so the boiler must not be covered and the
surrounding area must be kept clear.
Optional Internal Timeclock
•This operates on a 24-hour sequence. Around
the outside of the clock there are a number of
white tabs - these allow 15 minute switching
times. To set a boiler cycle simply push outwards
the number of tabs required for your heating
period.
Remember : tab OUT = BOILER ON
tab IN = BOILER OFF
The time of day is marked by an arrow on the
inner part of the clock - set the outer time to
coincide with this arrow.
On the centre part of the clock there is a switch.
This has three positions :
•Switch down - timeclock off
•Switch middle - timeclock timed (normal position)
•Switch up - timeclock on constant.

Connecting to the System
The ETS boiler is designed to operate on a sealed
system (ie. no open vent or feed and expansion
cistern). Hot water expansion within the system is
taken up by the internal 8 litre expansion vessel.This
is suitable for systems up to 128 litres
capacity. If the system capacity is more than this then
an additional expansion vessel may be required.This
can be fitted external to the boiler at a convenient
place on the pipework.
Please note that the circulation pump is fitted to the
flow connection.
Safety Valve Connection
The boiler safety valve (set at 3 bar) must be piped
to drain using metallic pipe (eg. copper) minimum
size 15mm.
Frost Protection
The boiler is NOTfitted with frost protection. If the
boiler is being installed in a position where freezing
could take place, then a suitable external frost
thermostat should be fitted.

Panel Removal
To mount the boiler, first remove the front cover panel :
-undo screws marked (A)
-tilt panel towards you and lift clear.
Then hang the boiler by positioning the hooks on the boiler over the wall bracket.Take care to ensure that the
automatic air vent does not touch the bracket bolts.
The final fixing point can be found behind the pump - drill an appropriate hole and fit the bolt supplied together
with the washer and nut.
For future maintenance only (not required when fitting the boiler) :
-To remove the control panel, undo screws marked (B) and draw panel towards you taking care not to pull off
any connections to the rear of the panel.
-To remove the top cover, unscrew the automatic air vent then undo screws marked (C).
