The installation and first ignition of the boiler must be
performed by qualified personnel in compliance with current
national regulations regarding installation, and in conformity
with any requirements established by local authorities and public
health organisations.
After the boiler has been installed, the installer must ensure
that the end user receives the declaration of conformity and the
operating manual, and should provide all necessary information
as to how the boiler and the safety devices should be handled.
This appliance is designed to produce central heating hot water for
domestic use only.
It should be connected to a heating system and a distribution network
for domestic hot water, both of which must be compatible with its
performance and power levels.
The use of the appliance for purposes other than those specified is
strictly forbidden. The manufacturer cannot be held responsible for
any damage caused by improper, incorrect and unreasonable use of
the appliance or by the failure to comply with the instructions given
in this manual.
Installation, maintenance and all other interventions must be carried
out in full conformity with the governing legal regulations and the
instructions provided by the manufacturer. Incorrect installation
can harm persons, animals and possessions; the manufacturing
company shall not be held responsible for any damage caused as a
result. The boiler is delivered in a carton. Once you have removed all
the packaging, make sure the appliance is intact and that no parts are
missing. If this is not the case, please contact your supplier.
Keep all packaging material (clips, plastic bags, polystyrene foam, etc.)
out of reach of children as it may present a potential hazard.
In the event of a fault and/or malfunction, turn the appliance off, turn
off the gas cock and do not attempt to repair it yourself. Contact a
qualified professional instead.
Before any maintenance or repair work is performed on the boiler,
make sure you have disconnected it from the electricity supply

I.S. 813
Domestic Gas Installations
Avoid installing the boiler where the air inlet can be polluted by
chemical products such as chlorine (swimming pool area), or ammonia
(hair dresser), or alkalin products (launderette).
Flue
Detailed information on flue assembly can be found in the
“Connecting the Flue” section.
The boiler must be installed so that the flue terminal is exposed to the
free passage of external air at all times and must not be installed in
a place likely to cause nuisance. It must not be allowed to discharge
into another room or space such as an outhouse or closed lean-to.
Condensing boilers have a tendency to form a plume of water vapour
from the flue terminal due to the low temperature of the flue gasses.
The terminal should therefore be located with due regard for the
damage or discolouration that may occur to building within the
vicinity and consideration must also be given to adjacent boundaries,
openable windows the min acceptable clearances are shown
opposite.
NOTE: THE FLUE MUST NOT BE INSTALLED IN A PLACE LIKELY TO CAUSE A NUISANCE AND
POSITIONED TO ENSURE THAT PRODUCTS OF COMBUSTION DO NOT DISCHARGE ACROSS
A BOUNDARY
It may be necessary to protect the terminal with a guard, if this is the
case it will be necessary to purchase a stainless steel terminal guard.
Reference should be made to the Building Regulations for guidance.
Ventilation
The room in which the boiler is installed does not require specific
ventilation. If the boiler is installed in a cupboard or compartment
ventilation is not required for cooling purposes.
Gas Supply
The gas installation and tightness testing must be in accordance with
the requirements of BS6891. Ensure that the pipe size is adequate for
demand including other gas appliances on the same supply.
Electrical Supply
The appliance requires an earthed 230V - 50 Hz supply and must be in
accordance with current I.E.E. regulations.
It must also be possible to be able to completely isolate the appliance
electrically.
Connection should be via a 3 amp double pole fused isolating switch
with contact separation of at least 3mm on both poles.
Alternatively, a fused 3 amp, 3 pin plug and unswitched socket may be
used, provided it is not used in a room containing a bath or shower, it.
It should only supply the appliance.
Water Supply
The boiler is suitable for sealed systems only. The maximum working
pressure for the appliance is 6 bar. All fittings and pipework for the
appliance should be of the same standard. If there is a possibility of
the incoming mains pressure exceeding 6 bar, particularly at night,
then a suitable pressure limiting valve must be fitted.
The boiler is designed to provide hot water on demand to multiple
outlets within the property. If there is a requirement for greater
demands, for example if the boiler has several bathrooms and
cloakrooms, a vented or unvented hot water storage system may be
used.
Showers
Any shower valves used with the appliance should be of a thermostatic
or pressure balanced type.
Refer to the shower manufacturer for performance guidance and
suitability.
11
installation
Flushing and Water Treatment
Location
The boiler is equipped with a stainless steel heat exchanger.
The detailed recommendations for water treatment are given in BS
7593:1992 (Treatment of water in domestic hot water central heating
systems); the following notes are given for general guidance.
If the boiler is installed on an existing system, any unsuitable additives
must be removed.
Under no circumstances should the boiler be fired before the system
has been thoroughly flushed; the flushing procedure must be in line
with BS 7593:1992.
We highly recommend the use of a flushing detergent appropriate for
the metals used in the circuit. These include cleansers produced by
Fernox BetzDearbon, whose function is to disolve any foreign matter
that may be in the system.
In hard water areas or where large quantities of water are in the
system the treatment of water to prevent premature scaling of the
main exchanger is necessary.
The formation of scale heat compromises the efficiency of the thermic
exchanger because small areas of scale cause a high increase of the
temperature of the metallic walls and therefore add to the thermal
stress of the heat exchanger.
Demineralised water is more aggressive so in this situation it is
necessary to treat the water with an appropriate corrosion inhibitor.
Any treatment of water by additives in the system for frost protection
or for corrosion inhibition has to be absolutely suitable for all metals
used in the circuit.
The use of a corrosion inhibitor in the sysem such as Fernox MB1, BetzDearborn Sentinel X100 or Fernox System Inhibitor is
recommended to prevent corrosion (sludge) damaging the boiler and
system.
If anti-freeze substances are to be used in the system, check carefully
that they are compatible with the metals used in the circuit.
ARISTON suggests the use of suitable anti-freeze products such as
Fernox ALPHI 11, which will prevent rust and incrustation taking place.
Periodicaly check the pH balance of the water/anti-freeze mixture of
the boiler circuit and replace it when the amount measured is out of
the range stipulated by the manufacturer (7 < pH < 8).
DO NOT MIX DIFFERENT TYPES OF ANTI-FREEZE
In under-floor systems, the use of plastic pipes without protection
against penetration of oxygen through the walls can cause corrosion
of the systems metal parts (metal piping, boiler etc), through the
formation of oxides and bacterial agents.
To prevent this problem it is necessary to use pipes with an “oxygen
proof barrier”, in accordance with standards DIN 4726/4729.
If pipes of this kind are not used, keep the system separate by
installing heat exchangers of those with a specific system water
treatment.
The boiler can be installed on any suitable internal wall (suitable
sound proofing may be required when installing onto a stud partition
wall). Provision must be made to allow for the correct routing of the
flue and siting of the terminal to allow the safe and efficient removal
of the flue products.
A compartment or cupboard may be used provided that it has been
built or modified for this purpose.
It is not necessary to provide permanent ventilation for cooling
purposes. Detailed recommendations are given in BS 5440 Part 2.
If it is proposed that it is to be installed in a timber framed building
then reference should be made to British Gas Document DM2, IGE/
UP/7 or advice sought from Gas Safe.
IMPORTANT
Failure carry out the water treatment procedure will invalidate
the appliance guarantee.
System Controls
The boiler is electrically controlled and is suitable for most modern
electronic time and temperature controls. The addition of such
external controls can be beneficial to the efficient operation of the
system. The boiler connections for external controls are 12V DC and
so only controls of 12V DC that have voltage free contacts should be
used. (page 25).
ARISTON supply a range of wired and wireless system controls.
Contact your supplier for more details.
12
Where a room sealed appliance is installed in a room containing
a bath or shower, the appliance and any electrical switch or
appliance control, utilising mains electricity should be situated
specifically in accordance with current IEE Wiring Regulations.
For unusual locations, special procedures may be necessary. BS
6798:2009 gives detailed guidance on this aspect.
installation
Condensate Discharge
The condensate discharge hose from the boiler must have a
continuous fall of 2.5o and must be inserted by at least 50mm into
a suitable acid resistant pipe - e.g. plastic waste or overflow pipe.
The condensate discharge pipe must have a minimum diameter of
22mm, must have a continuous fall and preferably be installed and
terminated to prevent freezing.
The discharge pipe must be terminated in a suitable position:
i) Connecting into an internal soil stack (at least 450mm above the
invert of the stack). A trap giving a water seal of at least 75mm
must be incorporated into the pipe run, there also must be an air
beak upstream of the trap.
ii) Connecting into the waste system of the building such as a
washing maching or sink trap. The connection must be upstream
of the washing machine/sink. If the connection is downstream of
the waste trap then an additional trap giving a minimum water
seal of 75mm and an air break must be incorporated in the pipe
run, as above.
iii) Terminating into a gully, below the grid level but above the water
level
iv) Into a soakaway
Note: If any condensate pipework is to be installed externally then
it should be kept to a minimum and be insulated with a waterproof
insulation and have a continuous fall. The total length of external
pipe used should not exceed 3 metres.
Some examples of the type of condensate terminations can be found
below.

Safety Valve Discharge and Condense Outlet
Gas connection
The pressure relief valve pipe is made of copper. It should terminate
below the boiler safely outside the premises. Care should be taken
that it does not terminate over an entrance or window or where a
discharge of heated water could endanger occupants or passers by.
Make sure, using the labels on the packaging and the data plate on
the appliance itself, that the boiler is in the correct country and that
the gas category for which the boiler was designed corresponds to
one of the categories available in the country where it will be used.
The gas supply piping must be created and measured out in
compliance with specific legal requirements and in accordance with
the maximum power of the boiler; you should also make sure that the
shut-off valve is the right size and that it is connected correctly.
Check that the supplied gas corresponds to the type of gas for which
the boiler was designed (see the data plate located on the appliance
itself ).
It is also important to check that the pressure of the gas (methane
or LPG) you will be using to feed the boiler is suitable, because if it
is insufficient the power may be reduced, causing inconvenience for
the user.
Warning !
Do not apply heat to the copper safety valve outlet pipe whilst it
is connected to the 3 bar safety relief valve.
Fill the central heating and DHW system and bleed air from the system
as described in the Commissioning instructions (page 30).
The system should be carefully checked for leaks, as frequent refilling
could cause premature system corrosion or unnecessary scaling of
the heat exchanger. The pipe from the trap should be connected to a
drain as described in the relevant regulations.
Pay special attention not to bend the condensate drain pipe in such
a way as to interrupt the flow. Please only use drain pipe material
compatible with condensate products (refer to BS 6798:2009).
The condensate flow can reach 2 litres/hour because of the acidity of
the condensate products (Ph close to 2), take care before operation.
See page 13 for condensate discharge options.
Water connection
The illustration below shows the connections for the water and gas
attachments of the boiler. See valves configuration on page 14.
Check that the maximum water mains pressure does not exceed 6 bar;
if it does, a pressure reducing valve must be installed.
For the measuring of the pipes and of the heating bodies in the
heating system, the residual head value should be calculated as a
function of the requested flow rate, in accordance with the values
shown in the circulation pump graph (page 16).

Connecting the Flue
Flue System
The provision for satisfactory flue termination must be made as
described in BS 5440-1.
The appliance must be installed so that the flue terminal is exposed
to outdoor air.
The terminal must not discharge into another room or space such as
an outhouse or lean-to.
It is important that the position of the terminal allows a free passage
of air across it at all times.
The terminal should be located with due regard for the damage or
discolouration that might occur on buildings in the vicinity, it must
also be located in a place not likely to cause nuisance.
In cold or humid weather water vapour may condense on leaving the
flue terminal.
The effect of such “steaming” must be considered.
If the terminal is less than 2 metres above a balcony, above ground or
above a flat roof to which people have access, then a suitable stainless
steel terminal guard must be fitted.
The minimum acceptable spacing from the terminal to obstructions
and ventilation openings are specified in Fig. 1.
Where 2 or more vertical fanned draught chimney configurations
teminate in close proximity at the same height they shall be separated
by at least 300mm. Where any 1 vertical outlet is more than 300mm
above the other, then they shall be separated by at least 1500mm.

Once cut to the required length, ensure that the flue is free from burrs
and reassemble the flue. If fitting the flue from inside of the building
attach the grey outer wall seal to the flue terminal and push the flue
through the hole, once the wall seal has passed through the hole, pull
the flue back until the seal is flush with the wall. Alternatively, the
flue can be installed from outside of the building, the grey outer seal
being fitted last.

Should the flue require extending, the flue connections are push fit,
however, one flue bracket should be used to secure each metre of flue.
Note: See table for maximum and minimum flue runs.
In the event that extension pieces need to be shortened, they must
only be cut at the male end and it must be ensured that the inner and
outer flue remain flush.

Fitting the 5” Flue (Ø 80 / 125 Horizontal/vertical)
Once the boiler has been positioned on the wall, it is necessary to insert the Ø80/125 adaptor (Fig. 5) for both horizontal and vertical flue
runs into the boiler flue socket (not supplied with flue kit - Part No
3318095).
Push the adaptor onto the boiler’s flue connection, grease the seals
then add extensions or elbows as required, secure the adaptor, using
the clamp and screws provided.
To fit extensions or elbows it is first necessary to ensure that the lip
seal is fitted correctly into the inner flue, once verified, it is simply necessary to push them together, no clamps are necessary to secure the
flue components.
Useable length of
vertical flue 575 mm*
Total length of

Before proceeding to fit the flue, ensure that the maximum flue length has not been exceeded (see the tables) and that all elbows and
bends have been taken into consideration. For each additional 90° elbow 1 metre must be subtracted from the maximum flue length, and
for each 45° 0.5 metres must be subtracted from the maximum flue
length (the height of the vertical adaptor and a 45° bend can be seen
in Fig.6 and a 90° bend in Fig. 7).
Note: DO NOT cut the vertical flue kit.

bends have been taken into consideration. For each additional 90°
elbow 1 metre must be subtracted from the maximum flue length,
and for each 45° 0.5 metres must be subtracted from the maximum
flue length (the height of the vertical adaptor and a 45° bend can be
seen in Fig. 8).
Fitting the Twin Pipe (Ø80 / 80)
Fig. 8a

Mark the position of the flue hole in the ceiling and/or roof (see Fig. 7
for distance from wall to the centre of the flue).
Cut a 130mm diameter hole through the ceiling and/or roof and fit
the flashing plate to the roof.
DO NOT cut the vertical flue kit.
To connect the vertical flue kit directly to the boiler, place the vertical
starter kit (Part No. 3318079) (see Fig. 7) onto the exhaust manifold
and secure with the clamp, fit the vertical adaptor onto the vertical
starter kit (Note: there is no need to use a clamp to secure this as it
is a push fit connection), the vertical flue kit must then be inserted
through the roof flashing, this will ensure that the correct clearance
above the roof is provided as the terminal is a fixed height.
Should extensions be required, they are available in 1 metre (Part
No. 3318077) and 500mm (Part No. 3318078) lengths. They must be
connected directly to the vertical starter kit before connecting the
adaptor to allow the vertical flue kit to be fitted. In the event that
extension pieces need to be shortened, they must only be cut at the
male end and it must be ensured that the inner and outer flue remain
flush.
When using the vertical flue system, action must be taken to ensure
that the flue is supported adequately to prevent the weight being
transferred to the appliance. Use 1 flue bracket per extension.
When the flue passes through a ceiling or wooden floor, there must
be an air gap of 25mm between any part of the flue system and any
combustible material. The use of a ceiling plate will facilitate this.
Also when the flue passes from one room to another a fire stop must
be fitted to prevent the passage of smoke or fire, irrespective of the
structural material through which the flue passes.
Note: See table for maximum and minimum flue runs.
Where it is not possible to terminate the flue within the distance
permitted for coaxial flues, the twin flue pipe can be used by fitting a
special adaptor to the flue connector and using the aperture for the
air intake located on top of the combustion chamber.
Always ensure that the flue is adequately supported, using one flue
bracket per extension and avoiding low points. (ARISTON supply
suitable clamps as Part No. 3318015).
To utilise the air intake it is necessary to:
1) Take the air intake cover off the top of the appliance
2) Assemble the air inlet adaptor - see fig. 8a
The twin flue pipes can be fitted with or without additional elbows
and need no clamps, simply ensure that the red o-ring is inserted in
the female end of the flue pipe and push the extension piece fully
into the previous section of flue pipe or elbow. Check that the o-ring
is not dislodged when assembling the flue (greasing the seal will aid
assembly).
When running the twin flue pipe vertically it can be converted back to
coaxial flue to enable vertical termination with a coaxial kit by use the
pipe bridge (Twin - Coaxial Adaptor - Part No. 3318089).
It is not possible to terminate concentrically horizontally. Termination
is only possible with separate air and exhaust terminals.
When siting the twin flue pipe, the air intake and exhaust terminals
must terminate on the same wall, the centres of the terminals must
be a minimum of 280 mm apart and the air intake must not be sited
above the exhaust terminal (refer to Fig. 10). The air intake pipe can
be run horizontally, however, the terminal and the final 1 metre of flue
must be installed either horizontally or with a slight fall away from the
boiler to avoid rain ingress.
It is also strongly recommended that the air intake pipe run be
constructed of insulated pipe to prevent condense forming on the
outside of the tube.
21
installation
The maximum permissible flue length for twin flue is
dependent on the type of run used (see table below).

For further information relating to flue runs not illustrated,
please contact the Technical Department on 0870 241 8180.
For coaxial systems, the maximum flue lengths listed in the
table below take into account an elbow.
For twin flue systems the maximum flue lengths listed in the
table below includes the exhaust gas/air intake terminal.
Type 5 outlets should respect the following instructions:
1- Use the same ø 80 mm flue pipes for the air intakes and
exhaust gas ducts.
2- If you need to insert elbows in the air intake and exhaust
gas ducts, you should consider for each one the equivalent
length to be included in the calculation of developed
length.
3- The exhaust gas duct should jut above the roof by at least
0.5 m.
4- The intake and exhaust gas ducts in Type C13 and C53
must be installed on the same wall, or where the exhaust
is vertical and the air intake horizontal, the terminals must
be on the same side of the building.

Commissioning Checklist and Service interval Record can be
found. It is important that this is completed in the presence of your
customer, they are shown how to use it, and it is signed by them.
Please instruct your customer that they must have this manual with
them whenever they contact a service engineer or us.
Preliminary electrical system checks to ensure electrical safety must
be carried out by a competent person i.e. polarity, earth continuity,
resistance to earth and short circuit.
Close all hot water draw off taps;
Open the cold water inlet cock supplied with the connection kit;
Slowly open each draw off tap and close them only when clear water,
free of bubbles, is visible.
Electricity supply
- Check that the voltage and frequency of the electricity supply
correspond to the data shown on the boiler data plate;
- Make sure that the earthing connection is efficient.
Gas Supply:
Inspect the entire installation including the gas meter and test for
tightness. The entire installation should be in accordance with the
relevant standards. In GB this is BS 6891 and in IE this is the current
edition of I.S.813.
The connection on the the appliance is a 15 mm nut and olive
located at the rear of the gas service cock.
If the gas supply serves other appliances, ensure that an adequate
supply is available both to the boiler and the other appliances when
they are in use at the same time.
Pipe work must be of an adequate size.
Pipes of less than 22 mm should not be used, final being 15 mm.
Open the gas cock (supplied with the connection kit) to the
appliance and check the gas connection on the appliance for leaks.
Filling the Heating System:

connection kit;
Lift the cap on the automatic air release valve and leave open
permanently;
Close all air release valves on the central heating system;
Gradually open the valves at the filling point (filling loop) until water
is heard to flow, do not open fully;
Open each air release tap starting with the lowest point and close
them only when clear water free of air is visible;
Purge the air from the pump by unscrewing the pump plug anticlockwise, also manually rotate the pump shaft in the direction
indicated by the pump label to ensure the pump is free;
Refit the pump plug;
Continue filling the system until at least 1.5 bar registers on the
pressure gauge;
Inspect the system for water tightness and remedy any leaks
discovered.

boiler protection devices
Boiler protection devices
The boiler is protected from malfunctioning by means of internal
checks performed by the electronic microprocessor P.C.B., which
stops the boiler from operating if necessary.
In the event of the boiler being shut off in this manner, the led code
shows the type of shut-off and the reason behind it.
There are two types of shut-off:
Safety shut-off
This type of error is “volatile”, which means that the boiler starts up
again automatically as soon as the problem which caused the shut-off
is removed; the yellow led 9 blinks and green CH temperature leds 1
indicate the error code- see table below.
As soon as the cause of the shut-off disappears, the boiler starts up
again and continues to operate normally.
Note : In the event of insufficient water pressure inside the heating
circuit, the boiler will perform a safety shut-off (yellow led 9 blinks - leds
50-60 blink – see table). To re-pressurise the boiler, it will be necessary
to connect the silver flexible hose supplied to the two isolating points
underneath the boiler, once the hose is connected, open up both of
the black quarter turn handles until the pressure reads 1.5 bar on the
pressure gauge. If the pressure drops very frequently, there may be a
water leak at some point in the system.
Shutdown
This type of error is “non-volatile”, which means that it is not removed
automatically.
The red led 8 light and green leds 1 indicate the error code- see table
below.
To restore normal operation press the
button on the control
panel.
Important
If this shutdown occurs frequently, contact an authorised
Technical Service Centre for assistance. For safety reasons, the
boiler will permit a maximum of 5 resets in 15 minutes (5 presses
button).
of the
Anti-frost Device.
When the electrical supply is turned on the anti-frost function acts
on the central heating flow temperature probe, independently from
other safety devices.
If the primary circuit temperature is between 3°C and 8°C the
pump will run (with the diverter valve switching between central
heating and hot water every 1 minute) until the temperature
reaches > 9°C.
If the flow temperature remains between 3°C and 8°C the pump will
continue to run for a maximum of 20 minutes unless a temperature
above > 9°C is detected in the central heating flow, after this the
burner will fire (heating position) until a temperature of > 30°C is
detected.
If the central heating flow temperature is < 3°C, the burner will fire
(heating position) at minimum power until the temperature reaches
> 30°C, the burner will go out.
If lockout is caused by overheat the burner will not fire but the pump
will continue to run (heating position).
The anti-frost device activates only when the boiler operating
correctly :
- the system pressure is correct;
- the boiler is electrically powered;
- there is a supply of gas.

Important
Maintenance is an essential part of the safe and efficient operation of
the boiler and ensures its durability. It should be performed according
to the instructions given in current legislation. Perform combustion
analysis regularly in order to check the operating efficiency of the
boiler and to make sure the combustion is within the boundaries set
by current legislation.
Before beginning maintenance work:
- Disconnect the appliance from the electricity supply by turning
the external bipolar switch to the “OFF” position;
- Remove the fuse;
- Close the gas valve and the central heating and domestic hot
water system valves.
After the work has been completed the initial settings will be restored.
liquid is added to the water in the heating system in order to avoid
the need for repeated draining; when this liquid is used make sure it is
compatible with the stainless steel used for the bodywork of the boiler.
We recommend the use of anti-freeze products which contain
PROPYLENE GLYCOLS as these inhibit corrosion and that they are
used in conjunction with the anti-scaling and anti-corrosion function,
in the quantities suggested by the manufacturer, at the mimimum
temperature.
Regularly check the pH level of the water/anti-freeze mix in the boiler
circuit and replace it when the value measured is lower than the limit
prescribed by the manufacturer.
DO NOT MIX DIFFERENT TYPES OF ANTI-FREEZE.
The manufacturer will not be held liable for any damage caused by
the appliance or the system due to the use of inappropriate anti-freeze
substances or additives.
General comments
It is recommended that the following inspections be carried out on the
boiler at least once a year:
1. Check the seals in the water part and, if necessary, replace the
gaskets and restore the seal to perfect working order.
2. Check the seals in the gas part and, if necessary, replace the
gaskets and restore the seal to perfect working order.
3. Visually check the overall condition of the boiler.
4. Visually check the combustion and, if necessary, disassemble and
clean the burner.
5. Following the inspection detailed in point “3”, disassemble and
clean the combustion chamber, if necessary.
6. Following the inspection detailed in point “4”, disassemble and
clean the burner and injector, if necessary.
7. Cleaning the primary heat exchanger
8. Make sure the following heating safety devices are operating
correctly:
- temperature limit safety device.
9. Make sure that the following gas part safety devices are operating
correctly:
- absence of gas or flame safety device (ionisation).
10. Check the efficiency of the domestic hot water production process
(test the flow rate and temperature).
11. Perform a general inspection of the boiler operation.
12. Remove oxide from the detection electrode using an emery cloth.
13. After servicing, complete the relevant Service Interval Record
section of the Benchmark Checklist located on page 54 of this
manual.
14. These checks are not exhaustive. Further mechanical, electrical
and combustion maintenance checks may be required.
15. Analyse combustion, see page 33.
Operational test
After having carried out the maintenance operations, fill the heating
circuit at a pressure of approximately 1.5 bar and release the air from
the system.
Fill the domestic hot water system at the same time.
- Begin operating the boiler.
- If necessary, release the air from the heating system again.
- Check the settings and make sure all the command, adjustment and
monitoring parts are working correctly.
- Check the flue system is sealed and operating correctly.
Draining procedures
The heating system must be drained using the following procedure:
- Switch off the boiler, make sure the external bipolar switch is in the
OFF position;
- Loosen the automatic air relief valve;
- Open the system drain off cock and collect the escaping water in a
container;
- Empty the water from the lowest points of the system (where
applicable).
If the system is to be left inactive in areas where the room temperature
may fall below 0°C during winter, we recommend that anti-freeze
Draining the domestic hot water system (E-COMBI)
Every time there is a danger of freezing, the domestic hot water system
must be drained as follows:
- Shut off the water mains inlet valve;
- Open all the hot and cold water taps;
- Empty the water from the lowest points of the system (where
applicable).
WARNING
Before handling, empty all components which may contain hot water,
performing bleeding where necessary.
Descale the components in accordance with the instructions provided
on the safety data leaflet supplied with the product used, make sure
the room is well ventilated, wear protective clothing, avoid mixing
different products, and protect the appliance and surrounding objects.
Seal all openings used to take a gas pressure reading or to make any
gas adjustments.
Make sure that the nozzle is compatible with the supplied gas.
If a smell of burning is detected or smoke is seen leaking from the
appliance, or there is a smell of gas, disconnect it from the electricity
supply, shut off the gas valve, open the windows and call for technical
assistance.
Cleaning the primary exchanger
The inside of the primary exchanger is accessed by removing the
burner. Wash with water and detergent using a non-metallic rifle-type
brush, rinse with water.
The trap is accessed by emptying the condensate bowl located in the
bottom section. Wash with water and detergent.
Replace the condensate collection bowl in its housing.
NB: In the event of prolonged of the appliance, the trap must be filled
before being used again.
A lack of water in the siphon is dangerous and may cause exhaust
gases to be released into the atmosphere.
Combustion Analyses
Details for flue gas analyses can be found on page 33.
Using a suitable calibrated combustion analyser, perform a combustion check. The CO2 valus can be found on page 33.
if the vlues are correct the CO/CO2 ratio must be less than 0.004.
Where combustion readings cannot be achieved carrefully check items
such as the burner, heat exchanger, flue system for defect.
Once satisfactors readings hane been achieved complete the relevant
service interval record selection of the Benchmark Commissioning
Checklist at the rear of this publication.
