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 ue assembly can be found in the
“Connecting the Flue” section.
The boiler must be installed so that the ue 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 ue terminal due to the low temperature of
the ue gasses. The terminal should therefore be located with
due regard for the damage or discolouration that may occur to
installation
building within the vicinity and consideration must also be given
to adjacent boundaries, openable windows should also be taken
into consideration when siting the ue.
The minimum acceptable clearances are shown below:
- A Directly below an opening, window, etc 300 mm
- B Horizontally to an opening, window, etc 300 mm
- C Below gutters, soils pipes or drain pipes 75 mm
- D Below eaves 200 mm
- E From vertical drain pipe or soil pipe 75 mm
- F From internal or external corner 300 mm
- G Above ground, roof or balcony level 300 mm
- H From a surface facing the terminal 2500 mm
- I From a terminal facing a terminal 2500 mm
- J Vertically from a terminal on the same wall 1500 mm
- K Horizontally from an terminal on the same wall 300 mm
- L Fixed by vertical ue terminal
N
ote: 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
specic ventilation. If the boiler is installed in a cupboard or
compartment ventilation is not required for cooling purposes.

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 red before the
system has been thoroughly ushed; the ushing procedure
must be in line with BS 7593:1992.
We highly recommend the use of a ushing 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 eciency 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.
4726/4729.
separate by installing heat exchangers of those with a
specic system water treatment.
IMPORTANT
Failure to 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 benecial to the ecient
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 24).
MTS supply a range of wired and wireless system controls.
Contact your supplier for more details.
Location
The boiler can be installed on any suitable internal wall
(suitable sound proong may be required when installing
onto a stud partition wall). Provision must be made to allow
for the correct routing of the ue and siting of the terminal
to allow the safe and ecient removal of the ue products. A
compartment or cupboard may be used provided that it has
been built or modied 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, GE/
UP/7 or advice sought from CORGI.
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 specically in accordance with current IEE Wiring
Regulations.
If pipes of this kind are not used, keep the system
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
MB-1, 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.
MTS suggests the use of suitable anti-freeze products such as
Fernox ALPHI 11, which will prevent rust and incrustation taking
place.
Periodically 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-oor 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.
For unusual locations, special procedures may be necessary. BS
6798:2000 gives detailed guidance on this aspect.
Codensate Discharge
The condensate discharge hose from the boiler must have a
continuous fall of 2.5
into a suitable acid resistant pipe - e.g. plastic waste or overow
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 down stream of if 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
o
and must be inserted by at least 50mm
To prevent this problem it is necessary to use pipes with an
“oxygen proof barrier”, in accordance with standards DIN
iv) Into a soakaway
installation
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.
1. Internal termination of condensate drainage pipe to internal
stack.
3. External termination of condensate drainage pipe via internal
discharge branch (e.g. sink waste - proprietary tting).
4. External termination of condensate drainage pipe via
condensate siphon
2. External termination of condensate drainage pipe via internal
discharge branch (e.g. sink waste) and condensate siphon.

Installing the Boiler
Please check that you are familiar with the installation
requirement before commencing work (pages 7 - 11).
The installation accessories described in the following list are
included in the boiler packaging:
- Hanging bracket
- A paper template (showing the dimensions of the boiler with
5 mm side clearances)
- Connection valves (compression)
- Screws and washers
- Filling loop
- Installation, Servicing and Operating Instructions
- Flue gasket
Method of positioning the boiler on the wall
The paper template can be used to ensure the correct
positioning of kitchen cabinets etc.
The paper template has to be xed to the wall and used to locate
the position of the hanging bracket and the centre for the ue
hole.
Drill and plug the wall and secure the hanging bracket using the
screws provided ensure the hanging bracket is level. Remove the
boiler from its packaging and remove the front casing panel.
Place the boiler on the hanging bracket.
N
ote: the appliaNce must Not be fitted oN a combustible wall surface.
Connecting the Boiler to the System
- Remove the boiler casing as described on page 13;
- Remove the caps and connect the valves to the boiler using
the washers provided;
- 3 x bre washers for the CH ow and return and cold water
inlet ;
Safety Valve Discharge and Condense Outlet
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.
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 26).
The system should be carefully checked for leaks, as frequent
relling 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 silicone drain
pipe is such a way as to interrupt the ow. Please only use drain
pipe material compatible with condensate products (refer to BS
6798:2000).
The condensate ow can reach 2 litres/hour because of the
acidity of the condensate products (Ph close to 2), take care
before operation.
See page 11 for condensate discharge options.

Gas connection
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 specic legal requirements and in accordance
with the maximum power of the boiler; you should also make sure
that the shut-o 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 insucient the power may be reduced, causing inconvenience
for the user.
Instructions for opening the casing and performing an
internal inspection
Before performing any work on the boiler, rst disconnect it from
the electrical power supply using the external bipolar switch
removing the fuse and shutting o the gas valve.
To access the inside of the boiler, the following is necessary:
1. Remove the casing by unhooking it from the control panel (a)
2. Loosen the two screws on the front casing (b), pull it forwards
and unhook it from the upper pins (c)

Underoor heating
For appliances with underoor heating, t a safety thermostat
onto the underoor heating outlet. For the electrical connection of the thermostat see the section on “Electrical connections
- page 24”.
If the outlet temperature is too high, the boiler will stop both domestic hot water and the heating production and the error code 1
16 “oor thermostat contact open” will appear on the display. The
boiler will restart when the thermostat is closed during automatic
resetting.
If the thermostat cannot be installed, the underoor heating equipment must be protected by a thermostatic valve, or by a by-pass
to prevent the oor from reaching too high a temperature.

Flue System
The provision for satisfactory ue termination must be made as
described in BS 5440-1.
The appliance must be installed so that the ue 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 ue terminal.
The eect of such “steaming” must be considered.
If the terminal is less than 2 metres above a balcony, above
ground or above a at roof to which people have access, then a
suitable stainless steel terminal guard must be tted.
The minimum acceptable spacing from the terminal to obstructions and ventilation openings are specied in Fig. 1.

Once cut to the required length, ensure that the ue is free from
burrs and reassemble the ue. If tting the ue from inside of the
building attach the grey outer wall seal to the ue terminal and
push the ue through the hole, once the wall seal has passed
through the hole, pull the ue back until the seal is ush with the
wall. Alternatively, the ue can be installed from outside of the
building, the grey outer seal being tted last.
Should the ue require extending, the ue connections are push

metre of ue.
Note: See table for maximum and minimum ue runs.
Using the ue clamp, seals and screws supplied (Fig 4) secure the
elbow to the boiler.
The 1 metre horizontal ue kit (3318073) supplied is suitable for
an exact X dimension of 753mm.
Measure the distance from the face of the external wall to the
face of the ue elbow (X - Fig 2), this gure must now be subtracted from 753mm, you now have the total amount to be cut

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 ue runs into the boiler ue socket (not supplied with
ue kit - Part No 3318095).
Push the adaptor onto the boilers ue connection, grease the

To t extensions or elbows it is rst necessary to ensure that the
lip seal is tted correctly into the inner ue, once veried, it is
simply necessary to push them together, no clamps are necessary to secure the ue components.
Before proceeding to t the ue, ensure that the maximum
ue length has not been exceeded (See the tables) and that all
elbows and bends have been taken into consideration, the maximum ue length is 10 metres, for each additional 90° elbow 1
metre must be subtracted from the total ue length, and for each
45° 0.5 metres must be subtracted from the total ue length (the
height of the vertical adaptor and a 45° bend can be seen in Fig.6
and a 90° bend in Fig. 7).

The vertical ue kit is supplied with a specially designed weather
proof terminal tted, it can be used either with a at roof or a
pitched roof.
The Vertical ue kits useable lengths with the pitched roof
ashings are indicated in Fig. 7.
Before proceeding to t the ue, ensure that the maximum
ue length has not been exceeded (See the tables) and that
all elbows and bends have been taken into consideration, the
maximum ue length is see table, for each additional 90° elbow
1 metre must be subtracted from the total ue length, and for
each 45° 0.5 metres must be subtracted from the total ue length
(the height of the vertical adaptor and a 45° bend can be seen in
Fig. 8).
Mark the position of the ue hole in the ceiling and/or roof (see
Fig. 7 for distance from wall to the centre of the ue).
Fig. 7
Cut a 130mm diameter hole through the ceiling and/or roof and
t the ashing plate to the roof.
DO NOT cut the vertical ue kit.
To connect the vertical ue 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, t 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 t connection), the vertical ue kit must
then be inserted through the roof ashing, this will ensure that
the correct clearance above the roof is provided as the terminal is
a xed height.
Should extensions be required, they are available in 1 metre (Part
No. 3318077), 500mm (Part No. 3318078) and 160mm lengths,
they must be connected directly to the vertical starter kit before
connecting the adaptor to allow the vertical ue kit to be tted.
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 ue remain ush.
When utilising the vertical ue system, action must be taken to
ensure that the ue is supported adequately to prevent the weight being transferred to the appliance ue connection by using 1
ue bracket per extension.
When the ue passes through a ceiling or wooden oor, there
must be an air gap of 25mm between any part of the ue system
and any combustible material. The use of a ceiling plate will facilitate this. Also when the ue passes from one room to another
a re stop must be tted to prevent the passage of smoke or re,
irrespective of the structural material through which the ue
passes.

installation
Fitting the Twin Pipe (Ø80 / 80)
When siting the twin ue 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 nal 1 metre of ue 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.
The maximum permissible ue length for twin ue is dependent
on the type of run used (see table on page 21).
For further information relating to ue runs not illustrated, please
contact the Technical Department on 0870 241 8180.
Use only the specic condensation ue kit
Note: See table for maximum and minimum ue runs.
Where it is not possible to terminate the ue within the distance
permitted for coaxial ues, the twin ue pipe can be used by
tting a special adaptor to the ue connector and using the aperture for the air intake located on top of the combustion chamber.
Always ensure that the ue is adequately supported, using one
ue bracket per extension and avoiding low points. (MTS supply
suitable clamps as Part No. 705778).
To utilise the air intake it is necessary to:
1) Take the air intake cover o the top of the appliance
2) Assemble the ange on the header supplied with the boiler
3) Insert the header on the tube or the elbow up until the lower
stop (you do not have to use the washer).
4) Insert the elbow/header in the boiler air intake hole and fasten
it with screws.
The twin ue pipes can be tted with or without additional
elbows and need no clamps, simply ensure that the red o-ring is
inserted in the female end of the ue pipe and push the extension piece fully into the previous section of ue pipe or elbow,
check that the o-ring is not dislodged when assembling the ue
(greasing the seal will aid assembly).
Twin pipe can also be converted back to Coaxial ue to enable
vertical termination with a coaxial kit by using the pipe bridge
(Twin - Coaxial Adaptor - Part No. 3318089). When running the
twin ue pipe vertically.
It is not possible to terminate concentrically horizontally. Termination is only possible with separate air and exhaust terminals.

For coaxial systems, the maximum development value, mentioned in the table below also takes into account an elbow.
For twin ue systems the maximum development value, mentioned in the table includes the exhaust gas/air intake terminal.
Type 5 outlets should respect the following instructions:
1- Use the same ø 80 mm ue 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 + 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

Only a 4 mm
allen key must be
used. Do not use a
screwdriver
Set the content by turning the screw about a 1/4 of a turn then
wait after each change for approximately 1 minute for the CO2
value to stabilise, then repeat.
Once the settings and analyses are complete, exit test mode, and
reposition the blanking cover and its seal correctly.
AUTO function
Inverno
This is a function which enables the boiler to automatically adapt
its operation routine (the temperature of the heating elements) in
line with the outdoor conditions, in order to achieve and maintain
the requested room temperature conditions.
Depending on the peripheral units connected and the number
of zones controlled, the boiler adjusts its ow temperature
automatically.
The various corresponding parameters should therefore be set
(see adjustments menu).
To activate the function, press the Auto button.

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 o in this manner, a code appears on
the display which refers to the type of shut-o and the reason behind it.
There are two types of shut-o:
Safety shut-o
This type of error is “volatile”, which means that the boiler starts up again
automatically as soon as the problem which caused the shut-o is removed; the error is indicated by the symbol which appears on the
display and the error code.
In fact, soon as the cause of the shut-o disappears, the boiler starts up
again and continues to operate normally.
In the event of error 1 08 - Shut-o due to insucient water pressure
inside the heating circuit - the boiler will perform a safety shut-o.
You can increase the pressure by lling the heating circuit.
In this case or if the re-balancing request is performed on a frequent basis,
switch the boiler o, turn the external electric switch to the OFF position,
shut o the gas cock and contact a qualied technician to check for any
leaks of water.
Shutdown
This type of error is “non-volatile”, which means that it is not removed
automatically. To restore normal operation press the button on the
control panel.
The rst gure of the error code (e.g. 1 01) indicates within which
operational assembly the error occurred.
1 - Primary Circuit
3 - Internal Electronic Part
4 - External Electronic Part
5 - Ignition and Detection
6 - Air inlet - ue gas outlet
7 - Multi-zone Heating
Malfunction warning
This warning is shown by the display in the following format:
5 P1 = FIRST IGNITION ATTEMPT UNSUCCESSFUL
the rst gure indicating the operational assembly is followed by a P
(warning) and the code relating to the specic warning.
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 of the RESET button); at the 6th attempt
within this 15-minute period the boiler will shut down and may only be
operated again after the electricity supply has been disconnected. If the
shutdown is occasional or an isolated event, this is not a problem.
Anti-frost Device.
The anti-frost function acts on the central heating ow temperature probe, independently from other regulations, when the electrical supply is
turned on.
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 ow 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 ow, after this the the burner will re
(heating position) until a temperature of > 30°C is detected.
If the central heating ow temperature is < 3°C, the burner will re (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 re but the pump will
continue to run (heating position).
The anti-frost device activates only when (with the boiler operating correctly):
- the system pressure is correct;
- the boiler is electrically powered;
- there is a supply of gas.

maintenance
Important
Maintenance is an essential part of the safe and ecient 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
eciency of the boiler and to make sure any polluting substances
relased are 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;
- Close the gas valve and the central heating and domestic hot
water system valve.
After the work has been completed the initial settings will be
restored.
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 ame safety device (ionisation).
10. Perform a general inspection of the boiler operation.
11. Remove oxide from the detection electrode using an emery
cloth.
12. These checks are not exhaustive. Further mechanical, electrical
and combustion maintenance checks may be required.
Operational test
After having carried out the maintenance operations, ll the
heating circuit at a pressure of approximately 1.0 bar and release
the air from the system.
- 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 ue system is sealed and operating correctly.
Draining procedures
The heating system must be drained using the following
procedure:
- Switch o the boiler, make sure the external bipolar switch is in
the OFF position and shut o the gas valve;
- Loosen the automatic air relief valve;
- Open the system drain o 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 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.
WARNING
Before handling, empty all components which may contain hot
water, emptying where necessary.
Descale the components in accordance with the instructions
provided on the safety data leaet supplied with the product used,
make sure the room is well ventilated, wear protective clothing,
avoid mixing dierent 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 o the gas valve, open the windows and
call for technical assistance.
Cleaning the primary exchanger
Cleaning the smoke side
The inside of the primary exchanger is accessed by removing the
burner. Wash with water and detergent using a non-metallic rietype brush, rinse with water.
Cleaning the trap
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 use of the appliance, the trap must
be lled before being used again.
A lack of water in the trap is dangerous and may cause smoke to
be released into the atmosphere.
