Materials used in the manufacture of this appliance are non-haz-
ardous and no special precautions are required when fitting or
servicing this appliance.
A load check should be taken into consideration when install-
ing high output boilers.
The boiler must be fitted on a wall that will provide an adequate
fixing, and should be fitted in a location that the boiler and
pipe-work are not subject to frost and damp conditions.
Detailed recommendations are given in BS EN 12828:2003,
BS 6700: 2006+A1: 2009 and CP 342-2:1974
Pipes forming part of the useful heating surface should be in-
sulated to prevent any potential heat loss or frost damage (BS
6700:1997).
Drain valves should be fitted at the lowest point of the system
pipe work in an accessible position.
Drain valves should be in accordance with BS 2879: 1980 and
copper tube to BS EN 1057: 1996. is recommended.
The boiler can be installed in almost any location within a do-
mestic or commercial property, however consideration should be
given to future maintenance. Never leave the boiler switched off
if there is danger of having temperatures below 0°C in the room
where it is located.
We recommend that a minimum clearance of 450 mm should be
allocated for the removal of the front cover and adequate access
to the boiler plumbing and the internal electrical connections. A
50 mm allowance should be made at either side of the boiler to
allow free flow air into the boiler case and allow access to screws
on the boiler case.

GB-031C_f.625
All Fusion Electric Boilers have a 22mm compression connection
at the boiler’s flow and return pipes. Please note that the boilers
are supplied with blank washers fitted for transit purposes. These
must be removed before connections to pipe-work can be made.
The flow (red) and return (blue) are clearly marked on the external
case and under no circumstances should these connections be
reversed. Hot connections are not recommended at the boiler for
future maintenance and boiler disconnection. Lockshield valves
are recommended.
Remove outer screws at the bottom of the boiler and pull the front
cover outwards taking care to remove internal earth connections.
Earth connections must be re-connected before the boiler case is
re-installed.
We recommend that lockshield isolation valves are fitted on the
flow and return pipework. Such valves must be „full way” and
not „ball valves”. The installation of „ball valves” in the flow and
return pipework will reduce the recommended flow rate through
the boiler and promote premature boiler shutdown.
An auto air vent is integral within the boiler however an addi-
tional auto air vent must be fitted at the cylinder coil if the boiler
is being used for central heating and domestic hot water.
Calculate the „space heating” requirements in accordance with
BS EN 12831 and BS EN 14336. If the boiler is to heat the do-
mestic hot water, an additional allowance of 3kW (10,239 Btu’s)
should be made to the ‘space heating’ calculation.
Where practical, and if at all possible, we recommend that all
pipe-work be insulated, in particular the primary pipe-work
with-in a boiler cupboard. This is to reduce heat loss and reduce
high cupboard temperatures from exposed pipe-work. (BS 6700:
2006+A1: 2009).
The boiler has an integral automatic bypass valve fitted which
should be set to the relevant settings to allow the minimum flow
rates to pass through the boiler (8 l/min) when all radiator thermo-
stats and zone valves are closed.
Allowance should be made for a radiator to be installed within
the heating circuit and locked open. This will be located in the
room that has the room thermostat installed.
To comply with building regulations, Part L and Part J (in Scot-
land), room and cylinder stats must be fitted.
the heating system (sealed systems). Reference should be made
to BS EN 14336 for the method of filling and make up of water.
There must be no direct connection between the boilers central
heating system and the main water supply. When mains water is
required to fill the system directly, all local water bylaws must be
observed, and any connection made must be disconnected after
use.
The system to within 10% of mains water PPM
to ensure that no debris is trapped in the flow sensor as this may
result in boiler failure. Where existing radiators and pipe-work
are utilized a power flush must be carried out to remove debris.
All boilers are tested to 4.0 bar. The normal working pressure of
the boiler should be set to approx 1.0 / 1.5 bar. All sealed sys-
tems should comply with the relevant building regulations and
standards, including BS EN 13831 – Specification for Expansion
Vessels.
In order to protect the Flow Sensor located within the boiler, it is
imperative that the pre-installed magnetic filter is removed and
cleaned at least annually. Failure to carry out this action will in-
crease contamination of the boiler by system residue.
The Fusion Comet range of boilers can be used in various system
designs. Please refer to The Electric Heating Company for more
details on our Fusion Boiler for under floor heating. We are able
to supply a heat pack that contains the relevant control valves,
cylinder and room thermostats required to configure an „S” plan
heating system. The heat pack has all the necessary components
that you need to connect the systems controls and plumbing con-
figurations for „S” Plan design.
We recommend the use of thermostatic radiator valves on all ra-
diators except in the room that has the wall thermostat fitted. This
radiator should be fitted with lock shield valves and left in the
fully open position.
The boiler has an integral automatic bypass valve fitted which
should be set to the relevant settings to allow the minimum flow
rates to pass through the boiler (8 l/min) when all radiator thermo-
stats and „zone valves are closed”.
Systems should be designed to meet the current building regula-
tions in force at the current time.
1. Hang the boiler in a vertical position on the fixing points and
screws provided, with the flow and return connections to the
bottom of the boiler, maintaining the clearances as per Figure
12 of this manual.
2. Connect the boiler to a heating system that is equipped with
isolation valves (see Figures 4 & 5).
3. Fill the heating system with treated water, which will substan-
tially extend the life of the heating coils. See item 14 „System
Protection” below.
4. Connect the boiler to the „mains” electrical system as per
Figures 6, 8, 9 & 11 using conductors sizes as per as specified
in the Technical Specification on page 17 of this document.
5. Connect the room thermostat / Programmer using the two
control conductors marked RP as in Figure 7 & 10.
6. For all other electrical connections refer to the ELECTICAL
CONNECTIONS & CONTROL section of this manual.

Failure to protect the system will invalidate the manufacturer’s
warranty.
After the system has been installed the cleansing and inhibiting
procedure must be carried out as follows:
1. Fill the system with cold mains water to the recommended
pressure 1.5 bar and check for leaks, then drain the system
thoroughly making sure all drain cocks are fully open and that
the system is completely drained.
2. Add Fernox Heavy Duty restorer through the header tank or
via filling loop at the recommended dose. One bottle must be
used as a minimum per dwelling. If you are unsure of the cor-
rect dose rate, contact Fernox.
3. Re-fill the system and circulate the Heavy-Duty Restorer prior
to the boiler being fired up, then commission the system in
the normal way. The cleansing agent must be in the system
for a minimum 1 hour with the system at normal operating
temperature. A longer period of time would be more beneficial
to the cleansing process especially if excess flux was used.
4. Drain and flush the system thoroughly to remove the cleaning
agent and any debris or contaminant. This is a critical part of
the cleaning process and must be carried out correctly. Use a
rinse test meter (TDS), such as the Fernox CTM. The reading
must be within 10% of the mains ppm value.
5. Then add the Fernox Protector (Copal MB1 or Super concen-
trate). This will protect against the formation of scale, corrosion
and microbiological growths. It is crucial however, that for
the protector to work correctly, the system must be properly
cleansed and flushed.
6. The label included within the Fernox Protector carton should
be completed and attached adjacent to the boiler.
7. We recommend inhibitor levels are checked on an annual basis
(usually during the service) or sooner if the system content is
lost. This should be carried out using a Fernox inhibitor Test
Kit.
8. Fernox Technical Service Helpline on 0870 870 0362 for further
assistance.
1. Ensure the system is filled with water and correctly vented.
2. Check if the appropriate system installation pressure is
reached(see the “TECHNICAL DATA” section). By using
or
but-tons whilst the control panel is off, the pressure value
will be displayed. When the installation pressure is too low The
“A’’indicator flickers (see “Operating’’ section). This doesn’t
concern open vented system installations.
3. Set the external controls to call for heat. Disconnect the flow
sensor wiring plug on the control panel.
4. Switch the boiler on (press button).
5.
Check the pump is set to the correct mode (see table below).
Todo this, press button for no more than 2 seconds. The
LED’sshould signal an operating mode at the place pointed by
arrow.
6. If the LEDs are signaling a different operating mode than rec-
ommended in the table below, set the appropriate mode ac-
cording to the following instructions: press button for longer
than 2 seconds, but less than 10 seconds (LED’s will start to
flash),the pump then switches to the settings mode. LEDs glows
to indicate the current settings. To change the settings of the
pump in accordance with the table below, you can set the right
combination of glowing LEDs by pressing
the button. Once
LED combination is set correct, by not pressing
the button for
10 seconds the pump will remember this setting and will exit
from setting mode back to performance view.
7. Ensure adequate flow through the boiler is reached (the
„H”indicator is on with a constant light). The pump should
self vent after a short period of running. if necessary assist the
venting process in the following way;
• close the isolation valve on the outlet,
• leave boiler running for 15 sec.
• open the isolation valve.
8. Switch the boiler off (hold button for 3 seconds).
9. Reconnect the flow sensor plug to the control panel.
10. Switch the boiler on (press button).
11. Set the boiler to the required system temperature, see the “Op-
erating” section.

We recommend the use of the EHC SINGLE CHANNEL PRO-
GRAMMER and EHC ROOM THERMOSTAT for heating only
installations.
For Heating and Hot water installations, we recommend the use
of the TWIN HEAT PACK which includes the EHC ROOM THER-
MOSTAT & AN EHC 2 CHANNEL PROGRAMMER.
The TWIN HEAT PACK will incorporate all the relevant parts to
comply with current building regulations i.e. Motorized valves to
control the heating and hot water circuits and Room and cylinder
thermostats to control the room and water temperatures. This will
also provide boiler interlock. The use of TRV’s alone will not pro-
vide boiler interlock.
We recommend the use of TRV’s, however they must not be used
in the room that has the room thermostat fitted.
Load check must be taken into consideration when installing high
power boilers. This will be carried out by a qualified electrician.
There may be an additional requirement to upgrade the incoming
main fuse supplying the property if other high power devices are
used within the property. E.g Electric Showers. If an electric shower
is present we recommend that a Shower Sensor is installed within the
system. This will cause an interrupt to the boilers control signal when
the shower is in use. It will disable the boiler protecting the electrical
system from overload.
All boilers must be protected at the meter position with a 30mA dou-
ble pole RCD with a minimum of 3mm contact separation accom-
panied by a suitably rated MCB. If the boiler is not fitted local to the
meter position then an additional isolation switch must be fitted local
to the boiler for each supply.
All pipe-work must be earthed in accordance with the IEE BS7671
Wiring Regulations.
After completion of all electrical works, an electrical safety check
should be carried out i.e. short circuit, earth continuity, resistance to
earth and polarity check, and all relevant Test Certificates completed
and issued to the customer.
Never open the front cover of the boiler until all power supplies to the
boiler have been disconnected.
The boiler connections are clearly marked inside the boiler L N E
(24hr LIVE).
The 24hr live is the permanent Feed connection to the boiler from
the mains supply. External controls will require an independent fused
spur supplied from the consumer unit, however this fused spur should
be supplied by the same power source & protected by the same RCD
as the boiler itself, the control circuit should be protected by a 6Amp
MCB. The Boiler & control circuit RCD should be independent of all
other domestic circuits. The boiler supply cable should be calculated
by the means of a cable calculation in accordance with BS7671 by a
suitably qualified electrician.

GB-031C_f.625
After the cleansing and protection of the system has been carried out,
set the external controls to the customers selected times.
If an off-peak electric meter has been installed by an Electricity Com-
pany to supply OFF-peak rate electricity at selected times, the ap-
propriate settings should be entered into to the system programmer to
take advantage of the OFF-peak rate electricity.
The boiler has an inbuilt pressure sensor. If the boiler has been
switched on with a low or no water content, the system will sense
this and prevent the boiler from sending power to the main elements.
After the system has been filled with water and has had a cold flush
the Fernox cleanser should be added, the system filled with water,
purged of air and set to the correct pressure of 1.5 bar (sealed sys-
tems). At this point the main power may be switched on.
At this stage you may carry out the cleansing and protection of the
system. Refer to the installation section of this manual. (See page 7).
The boiler PCB has a voltage free connection for the controls (RP) &
(NA). Under no circumstances should 240V be connected to these
controller block connections as this will damage the boiler’s PCB and
Void the Manufacturers warranty.
The stat / programmer connections are clearly marked within the
boiler.
Only after all connections have been made and checked should the
system be filled with water and set to the proper pressure 1.5 bar
(Sealed systems).
Check the system for leaks. If water leaks into the boiler this may
damage the boiler electrics and the manufacturers warranty will be
invalid.
Under no circumstances should the boiler be switched on when the
system is dry.

GB-031C_f.625
Unlike other system boilers such as Gas, Oil and Propane the
FUSION „Comet” range of electric boilers require no ignition or
lighting sequence to be executed by the end user. All the end user
is required to do is ensure that the system is filled with water and
the room thermostat or programmer is calling for heat.
2.1 Switch the boiler on by pressing the button. (Note: When
switching the boiler off use the same button by pressing
and holding it in for 3 seconds.).
2.2 The recommended Water Pressure is approx 1.0/1.5 bar and
this can be checked by pressing the button until indicator
A is illuminated. The water pressure can be adjusted by con-
necting the external filling loop and pressurizing to the desired
pressure. Note: the filling loop must be disconnected after the
system has been re -pressurized.
2.3 First set the required Boiler Temperature (we recommend
a setting of 65
0C) by pressing the button until only indicators
D and K are illuminated. Press the button or the button
until the desired temperature setting is achieved.
2.4 Ensure the room thermostat is switched on and is calling for
heat. If the boiler is not yet at the desired heat setting then
indicators D, G, H, I, J & K will be illuminated with indictor K
illuminated in red. Once the room has reached the required
setting the K indicator should change from red to green. Refer
to the Control Panel diagram above to learn how to adjust to
the right temperature to make the boiler work comfortably and
economically.
2.5 The boiler Flow Rate is set at 8 l/min during the installation
of the boiler. To check this setting then press the button a
number of times until only indicator B is illuminated and then
read the figure on the digital display. If the figure is well below
the 8 l/min figure then call a Service Engineer for assistance.
2.6 To check the amount of kW energy being used by the boiler at
any point in time then press the button a number of times
until only indicator C is illuminated and then read the figure
on the digital display.
2.7 When indicator H is illuminated the pump is running.
We recommend the boiler temperature be set to 65°C. Raise or
lower the temperature in your installation with the buttons on
the right hand side of the control panel as per 2.3 in the previous
section.
„”
The customer has the option to switch the boiler onto „stand-
by” mode during summer months and this can be carried out by
pressing the „button and holding this in for 3 seconds”.
All indicators will go off except the F indicator which will inter-
mittently illuminate.
In the „stand-by” mode all the boiler functions are switched off
except the circulation pump. This is activated for 15 minutes
each day which protects the boiler and the whole central heating
system from being blocked and silted up. In this „stand by” mode
the circulation pump will run each day at the same time. (e.g. If
you switch the boiler to „stand by” at 6pm then the circulation
pump will run every day at 6pm for 15 minutes) To return to a
„Winter” mode setting then press and hold the button for 3
seconds again.
In the Winter mode setting the digital display will be active and
will show the temperature of the water at various points within
the boiler. Those indicators which are illuminated will show the
current status of the boiler. If the boiler is being called for heat
by the thermostat then the G, H, I, J & K indicators will be illumi-
nated. In the winter mode both the two port valves are active and
they will direct heat as required.
