The fireplace must always be operated with a self-closing door. Modification
of the closing device is prohibited! Coasting temperature surfaces can/must
be integrated in the connecting line to the chimney. These downstream
heating surfaces must only reduce the flue gas temperature to the extent
possible for safe and suitable operation of the flue gas system! The Nova E
H2O insert serves as a supplemental heat generator for
water heating systems in accordance with DIN EN 12828, as the specified
nominal heat output only occurs as long as the insert is fired with nomi-
nal heat output. The fireplace can be operated manually or with suitable
combustion controllers and appropriate settings. If necessary, consult with
Spartherm Feuerungstechnik GmbH in this regard.

1. GENERAL INSTRUCTIONS
Prior to setup and installation of the tiled stove system, Nova E H2O, a
discussion must be conducted with your responsible district master chimney
sweep. He will advise you of building law regulations, the suitability of your
chimney, and will execute the acceptance procedure of your tiled stove. The
chimney calculation is executed in accordance with DIN EN 13384 with the
value triplet specified in this manual (see technical data).
OUR HEATING INSERT HAS BEEN TESTED IN ACCORDANCE WITH
DIN EN 13229 AND SATISFIES THE REQUIREMENTS STIPULATED
IN THE CONSTRUCTION PRODUCTS DIRECTIVE. (DECLARATION
OF PERFORMANCE IS AVAILABLE AND CAN BE VIEWED AT WWW.
SPARTHERM.COM)
Small children, elderly or infirm persons: As is the case with all heating
devices, it is expedient that you attach a protective fixture for these groups
of persons, as the view pane and also the cladding parts can become
extremely hot! Danger of burn injuries! Never leave these groups of persons
unattended near the fireplace when a fire is burning or has just been
extinguished!
National and European standards, the respective state-specific and local
directives and regulations, in particular the respective firing installation
ordinance of the German Federal State, must be complied with for the setup
and operation of your insert and for the connection to the chimney. For
improved capacity utilisation of the high flue gas temperatures a water heat
exchanger is integrated on the walls and in the flue gas collector. A service
water storage tank, buffer tank, etc. can be heated with the generated hot
water. If these or similar system components are not available, then through
other structural measures, safe and continuous heat dissipation must be
ensured.

2. INSTALLATION
The installation of the water-bearing components, the necessary safety
devices, etc. must always be executed by a specialised company. The Nova
E H2O must be installed in such a manner that all components, including
those that are behind the cladding, are accessible and can be checked at
all times! After setup, connection and filling of all installations, and prior to
producing the heating chamber (enclosing brick work), the fireplace insert,
as well as the associated heating installations, must be checked for leaks
through a pressure test. If costs are incurred through dismantling of the
heating chamber due to leaks on the Nova E H2O, the manufacturer is not
responsible for these costs.
For the installation, strictly ensure that the Nova E H2O is aligned horizontally
by adjusting the height of the insert feet, or that it is aligned with a slight
incline toward the front side vent plug.
2.1 BASIC REQUIREMENT IMPOSED ON SETUP
The Nova E H2O tiled stove must only be mounted in thermostatically
safeguarded systems in accordance with DIN 4751 or DIN EN 12828. All
connections to the heating network must always be designed so that they
can be detached (e.g. as threaded union). Only use temperature-resistant
pipelines within the fireplace cladding. When using sealing materials,
strictly ensure adequate temperature resistance! All safety devices must
only be mounted in the „cold“ range, to max. 80°C or they must be mounted
outside of the fireplace cladding. The temperature resistance of the safety
devices is generally inadequate for mounting within the fireplace cladding!
All water-bearing components must be protected against freezing! When
mounting, the instructions in the installation and operating manuals of the
supplemental components installed must always be complied with! For
installation, connection and operation of the Nova E H2O fireplace insert,
all necessary national and European standards, as well as local regulations

GB
GB 9
2.2 ELECTRICAL CONNECTION
The entire electrical installation of the individual components of the heating
system must only be executed by an authorised specialised company. In this
regard, all tasks must be executed in accordance with the VDE regulations
(e.g. VDE 0105, VDE 0116, VDE 0100, etc.), and in accordance with the
technical connection conditions specified by the local electricity supplier
2.3 CONNECTIONS OF THE NOVA E H2O
All pipeline connections are on top, on the front side of the tiled stove (see
Fig. 2a). These connections must always be accessible through front doors,
pipe doors, ventilation grilles, etc. For transport purposes the connections
are provided with transport safeguards. These must be removed for the
installation. The connections are clearly labelled and must not be used other
than for the specified purpose! Likewise, the integrated safety device (safety
heat exchanger) must not be used to heat water. For the pipe connections
we recommend the use of straight or angled radiator threaded unions.
(DIN, DIN EN, state construction ordinances, firing ordinances, etc.) must be
complied with and applied!

Integration of the Nova E H2O in a heating system: Please note: Fig. 2b
shows one possibility of how the Nova E H2O can be integrated in an exist-
ing heating system. However this example does not replace the detailed
planning of the installation by a specialised company:
For heating lines, we recommend a minimum nominal pipe diameter of:
Copper pipe, at least 28 x 1.0 mm or steel pipe, min. 1"(DN25, 33.7 x
3.25 mm) or larger. However, the integration must always be executed after
configuration by a specialised company.
2.4 MINIMUM CROSS SECTIONS - CONVECTION AIR
The minimum cross sections for convection air (supply air and recirculating
air) for the heating insert with metallic coasting temperature box in the
cladding or in the heating chamber must be designed as follows.
Hot air: 990 cm² at the upper points in the cladding
Cold air: 990 cm² at the lower points in the cladding
Minimum cross sections if connecting lines are shorter than 1.0 m and flue
gas connection on the upper flue gas connection:
Hot air: 450 cm2
Cold air: 370 cm2
In addition, the Regulations of the German Tiled Stove and Air Heating
Constructors Association (TR-OL 2006) must also be taken into account.
2.5 VENTILATION
For ventilating the water heat exchanger, the ventilation plug, as described
under point 2.3, must be used. This ventilation plug can be replaced with
a suitable automatic vent for example, if the heating chamber temperature
does not cause the heating water to boil inside the automatic vent.
2.6 SAFETY VALVE
In the direct vicinity of the Nova E H2O, a type-tested safety valve (e.g. make
Syr, type 1915) with an activation overpressure of max. 3.0 bar must be
mounted in the flow line. When mounting, the manufacturer‘s specifications
(e.g. ambient temperature) of the safety valve must be taken into account. A
shut-off possibility must not be integrated in the system between the safety
valve and the Nova E H2O. This could render the safety device inoperable.
Moreover, all necessary safety devices must be integrated in the entire
system in such a manner that safe operation is ensured.

GB 12
2.8 THERMAL DISCHARGE SAFETY DEVICE
As the heating of the Nova E H2O is not automatic, nor can it be quickly
shut-off, the hot water insert must be equipped with a thermal discharge
safety device in accordance with DIN 4751 - Part 2 and DIN EN 12828 to
avoid dangerous situations in the case of malfunction, such as a power
outage. For this, a safety device (safety heat exchanger) is integrated in
the Nova E H2O to prevent overheating. This safety device must not be used
as a water heater. The provided thermal discharge safety device (e.g. SYR,
type 3065) has been tested and approved for a minimum water throughput
of 900 kg/h. The connection can be executed in accordance with Fig. 2. The
sensor of the capillary tube must be pushed into the appropriately marked
connection opening of the Nova E H2O (into the sealed-in immersion sleeve)
and permanently fixed in place.
The following instructions must always be complied with for the installation,
so that the safety device can function:
• For the installation, the instructions in the installation and operating
manual for the thermal discharge safety device provided by the manu-
facturer must always be complied with!
• The fitting of the thermal discharge safety device must only be installed
in the flow line, so that when operated as intended, standing water is not
present in the safety heat exchanger.
• The fitting of the thermal discharge safety device must not be housed
in the hot area of the heating chamber (convection chamber) of the fire-
place system (max. ambient temperature 80°C). Select the position of
the fitting in accordance with the capillary tube length so that it is easily
accessible, should it be necessary to replace the fitting for example!
• At the cold water inlet, a flow pressure of at least 2.0 bar
must be available. This pressure must be constantly ensured.
The possibility of water network fluctuations must be excluded.
For example, this means that a mains voltage-dependent domestic water
supply is not approved!
A separate safety valve must also be installed, if such a safety valve is
installed at a different point in the entire system (comply with TRD 721!)
2.7 RETURN FLOW TEMPERATURE BOOST
The Nova E H2O must only be operated with a return flow boost. In operation,
the return flow temperature must be at least 60°C to prevent damage to
the boiler parts.
Likewise, sooting of the fireplace insert, as well as faster contamination
are also prevented. To ensure a temperature of at least 60°C, a circulation
pump/return flow temperature boost must be installed in such a manner that
it only starts up when a temperature of approx. 62°C has been reached. This
is ensured if a pump thermostat (Afriso, type GTK 7HD) is used. As there
is a danger of undershooting the dew point, a regulated return flow boost
must be installed. In this regard, the control variable - this equals the effec-
tive return flow temperature at the inlet of the water heat exchanger - is
detected and adjusted to the desired value.
The return flow temperature boost should be installed in the direct vicinity
of the heat generator, so that the phase of dew point undershooting at the
flue gas water heat exchanger is kept as short as possible. However, it must
be noted that with installation of the circulation pump within the heating
chamber, operating noises are perceptible.
Please note: For operating malfunctions or corrosion damage (sooting,
deposits, etc.) on the water heat exchanger or chimney, etc. that are
attributed to a missing return flow boost or non-effective return flow boost,
we can accept neither liability nor guarantee.

GB
GB 13
• Minimum water throughput of approx. 900 kg/h must be ensured. It must
not be possible to shut off this supply line!
• The heating insert must be aligned so that the front vents are at the
highest point.
All safety-relevant components must be integrated in the system in such a
manner that the function and the leak tightness can be checked at any time.
The discharge of the thermal discharge safety device must be designed in
such a manner that a check (e.g. via a drain with siphon) can take place
at any time.
2.9 THERMAL PUMP CONTROLLER
The fireplace insert/tiled stove insert must always be operated with a
suitable return flow temperature boost. The thermostat switch necessary
in this regard is provided with the insert. The associated wrapped capillary
tube must be carefully unwrapped and pushed into the labelled immersion
sleeve on the front, top left, and secured with the provided clamp. The
thermostat switch must be electrically wired to the power supply and the
return flow boost (circulation pump). This ensures that the circulation pump
only starts up at a sufficient water temperature and switches off if the
specified temperature is undershot.

The blue conductor is

The connection is executed in
accordance with Fig. 3a.
The zero conductor and the PE conductor of the supply line are connected to
the circulation pump or the return flow boost. The circulation pump should
only be controlled via a boiler controller or similar devices if the controller is
appropriately suitable. For the installation, the instructions in the installation
and operating manual of the built-in thermostat must be complied with! The
sensor of the thermostat must be pushed into the appropriately marked
connection opening of the Nova E H2O (sealed-in immersion sleeve) and
permanently fixed in place. The maximum load capacity of the thermal pump

GB 14
controller is approximately 500 W at alternating current AC 230.
The factory settings of the thermostat have been pre-set to approximately
62°C. With this pre-set, the switch-on temperature and switch-off
temperature of the circulation pump of the return flow boost are defined
when the necessary water temperature in the water heat exchanger
is reached or undershot. Optionally, if the conditions so require, the
temperature can be adjusted by the installation company. For this, depend-
ing on the version of the thermostat, the rotary adjuster is adjusted, or the
cover (D=10 mm) is taken off. After removing the cover, the temperature
range can be changed. The pump thermostat must not be housed in the hot
area of the heating chamber (convection chamber) of the fireplace system
(max. ambient temperature 80°C). Select the position in accordance with
the capillary tube length in the cold area!
Please note: At water temperatures below 60°C the danger of undershooting
the dew point increases! This can cause gloss soot. In addition, the clean-
ing interval is shortened. Consequently, we recommend that the switch-on
temperature is not to be set below 60°C and not above 68°C. For some
heating systems, it can be necessary to install a flue gas thermostat in
addition to the pump thermostat. This prevents the buffer tank from cool-
ing above the tiled stove insert. Ask the installation company if there are
questions in this regard
2.10 INTEGRATION IN A HEATING SYSTEM
Please note: The Nova E H2O must only be installed in an overall system
after detailed planning of the overall heating system in accordance with the
relevant rules of technology and the safety standards. The proper configura-
tion of the pumps, fittings, pipeline, buffer tank and the safety components,
such as safety valve and expansion tank, is the responsibility of the planning
firm and/or of the executing installation company. Bear in mind that during
the combustion phase, extremely high water throughput of approx. 25 kW
can briefly occur. The heating installations must be configured accordingly,
among other things.
The following sample calculation can be helpful for dimensioning the buffer
tank:
The following assumptions have been made in this regard:
• PSize of the buffer tank: 500 l (approx. 500 kg water)
• Water temperature in the buffer tank at the beginning: 30 °C
• Water temperature in the buffer tank at the end: 60 °C
• Temperature differential 30 °C (corresponds to 30 K))
• No heat withdrawal from the buffer tank during warm-up by the Nova E
H2O and no heat losses from the syste
This means: To heat up 50 litres of water in a buffer tank, from an assumed
30°C to 60°C a theoretical heat quantity of 62805 kJ (= 62805 kWs) is
required (losses or heat withdrawals in the system have not been taken into
account). This heat quantity corresponds to approx. 17.5 kWh. However,
with an effective setup of the heating system, e.g. of a stratified storage
tank, the heat utilisation can begin shortly after start of circulation in the
Nova E H2O. In this case, only the excess energy will be stored in the buffer
tank, not the energy required for heating.
At an average assumed power of approx. 9 kW of the Nova E H2O, heat-up
of the entire buffer tank takes just under 2 hours.
On extremely cold winter days, it is possible that the fireplace system may
also be in operation for approximately 12 hours. In this case, the thermal
energy thus produced is theoretically 93 kWh. This thermal energy would
then be sufficient to heat just under 2,666 litres of water (from 30°C to
60°C). As a rule, in such a situation heat is also continuously withdrawn so
that overloading of the buffer tank (> 90°C) should not occur.

GB
GB 15
2.11 CHIMNEY CONNECTION / CONNECTING PIECES
The Nova E H2O is connected to the chimney with the connecting pieces
made from steel sheet at least 2 mm thick. These connecting pieces
must satisfy the requirements specified in DIN 1298 and DIN EN 1856-
2, and must be connected to the chimney / flue gas system in accord-
ance with the requirements specified in DIN 18160 or the country-specific
regulations. It must be ensured that the flue gas pipe takes the shortest
possible route upwards towards the chimney. The number of bends in the
flue gas pipe should be kept to a minimum. In addition, the flue gas pipe
must be connected to the chimney with a bricked-in wall lining and sealed.
If necessary, the flue gas pipe must be fastened with clamps to ensure
adequate fixation. The connecting pieces must be sealed if necessary! If the
flue gas pipe is routed through components with flammable building materi-
als, the flue gas pipe must be insulated as specified in the regulations. The
connecting line must always be mounted in such a manner that it is possible
to clean the connecting line at any time.This must be ensured through a suf-
ficient number of cleaning openings. A gauge connection must be installed
so that it is accessible for determination of the negative chimney pressure
in the connecting line.
2.12 INSTALLATION OF ROTATING DISC / AIR
ADJUSTMENT LEVER / SERVOMOTOR FOR
S-THERMATIK
After delivery, it may be necessary to mount the rotating disc through the
combustion chamber in the floor area of the tiled stove (e.g. device design
with S-Thermatik). Installation is not executed in the factory because the
star adapter (frictional connection between servomotor and rotating disc),
as well as the servomotor for the S-Thermatik project downwards out of
the device. These components would be damaged through transport and
installation.
For installation, removal of the front combustion chamber chamotte (cha-
motte brick no.: 7 and 8 Fig. 4) and of the combustion chamber floor are
necessary. Installation of the air mechanism must be executed as shown
in Fig. 3a. The air adjustment lever must be in the „closed“ position (air
adjustment lever at the left stop), so that the primary ventilation damper
can be inserted. After installation, the function of the air controller must be
checked before installation of the combustion chamber floor. For this, the
inspection opening in the front chamfer of the combustion chamber bowl
must be opened. Through this opening, it must be possible to determine the
opening of the primary ventilation damper when the air adjustment lever
is in the right position. If the air adjustment lever is turned to the left, the
primary ventilation damper must close.

2.13 CHANGING THE DOOR STOP
If the door stop is to be changed, this is also possible after the overall
system has been completed. For this, a new door must be ordered with
specification of the order number, which then can be replaced thanks to
the universal frame.
1. Removal of the „old“ door
a.) First, remove the securing clip on the upper pivot hinge.
b) Then open the door as far as possible and deactivate design A1. To do
this, tighten the grub screw that is located on the bottom on the hinge
side with an Allen key.
Then take the tiled stove door out of the tiled stove - to do this lift the door
on the hinge side and pull it downwards and forwards.
2. Replacement of locking pin
c) Use an open-end wrench to dismount the locking pin.
d) Mount the locking pin on the opposite side, where a bore is provided.
3. Insertion of the „new“ door
Insert the „new“ door - to do this, slide the door with the upper pivot
hinge into the provided bores. Then open the door 90° and fit the lower
pivot hinge (hexagonal) into the provided bore.
e) Reactivate design A1. To do this, unscrew the grub screw that is located
on the bottom on the hinge side with a 3 mm Allen key.
Now check the door for proper function! If the door does not close on its
own, it must be readjusted. If the door does not close on its own, operation
is not permitted.
f) Finally, reinsert the securing clip on the upper pivot hinge.

The deflector plate (9) must be guided
into the combustion chamber diagonally
until it is above the side walls (see Fig.
5b). Then the deflector plate must be
rotated horizontally in the free space
above the side bricks and placed in the
centre on the side bricks. In this regard,
it is important that the top side of the
deflector plate must be the rough top
side and that the rear surface must have
the appropriate pattern notches of the
rear wall bricks. The deflector plate must
be pushed in until it is on the rear wall
chamotte.
The baffle plate (10) must be inserted in
the same manner (see Fig. 5c), however
it is positioned as shown in Fig. 5d on
the front of the device with a clearance
of 15-30 mm.
2.14 COMBUSTION CHAMBER LINING
Installation of the combustion chamber lining
The individual chamotte bricks of the combustion chamber lining must be
installed as numbered, starting with number (1). The rear wall chamotte
bricks (2a to 2c) have the same dimensions so that they do not need to be
differentiated.

The slot that occurs between the steel
body and the baffle plate is a measure
for reducing the smoke that escapes
from cold tiled stove inserts in the case
of flue gas systems with excessively low
delivery pressure in the start phase.If the
insert is in operation for approx. 15-20
minutes, the necessary delivery pressure
is built up via the after-burning zone
or the flue gas system and the heating
gases are almost exclusively discharged
to the rear.
Through the arrangement of the deflector plate and baffle plate, an
after-burning zone is produced where extremely high heating gas
temperatures occur. Fine dust particles and carbon are burned in this zone.
The combustion chamber lining is removed in the reverse sequence. Impor-
tant: When removing and installing, you must ensure that the chamotte does
not hit against edges, fall over, etc. The service life of the elements of the
combustion chamber lining is reduced through mechanical damage.
If replacement chamotte bricks are required, they can be requested through
the stove fitter with the appropriate order numbers.
3. INITIAL COMMISSIONING
Heat generation systems must only be produced and installed by specialised
companies. The initial commissioning must only be executed by an expert
employee of the installation company. A certificate confirming proper
installation and proper adjustment / function of all control components and
safety components must be given to the owner / operator of the system.
The initial commissioning must only be executed after all necessary
components are connected and all necessary safety devices are integrated
and functional. Before the stove / fireplace insert is placed in service, it
must be filled and ventilated on the heating side (heating network) and water
side (thermal discharge safety device; safety heat exchanger). After the fill-
ing process, check all hydraulic connections for leaks. Operation without
a water-side connection results in irreparable damage and invalidates any
warranty claims!
The first four firings must each be executed with max. 2.0 kg/hour of dry
and thin wood (max. circumference 25 cm). Through this measure the
fireplace insert, the chamotte and the vermiculite are slowly tempered and
thus the moisture that may be present due to storage, transport, etc. is
slowly dissipated. If this does not occur, contamination of the area between
the glass panes, as well as tearing of the chamotte are possible.
Moreover, the operator must be instructed in detail concerning the operation,
function and maintenance of the overall system, including all supplemental
components. In addition, the measures for maintaining safe operation of
the system must be communicated to the operator. Execution of instruction
must be documented in the commissioning protocol! The installation and
operating manual must always be kept in good condition in the vicinity of
the Nova E H2O, where it can be easily accessed.
4. OPERATION
For operation, also comply with the instructions in the operating manual
of the fireplace inserts. The instructions in this installation and operating
manual refer to special operation of a heating insert with integrated water
heat exchanger, such as the Nova E H2O.

• The fireplace insert locking door must always be operated with a
self-closing door. This means that the combustion chamber door is gen-
erally closed. The door may only be opened to put on more firewood or
for cleaning when in a cool state. Manipulation of the closing device is
prohibited.
• The distance between flammable parts/furniture and the view pane must
be at least 80 cm!
• The fireplace insert is designed for the burning of dry, untreated wood
logs with adhering bark and wood briquettes.
• Operation in the partial load range results in low flue gas temperatures.
Continuous operation of the Nova E H2O in the partial load range can
cause chimney damage. For this reason, we recommend an hourly wood
feed quantity of 5-6 kg during a burning day. The quantity of wood to
be supplied should not be less than 2/3 of the recommended wood feed
quantity.
• The thermally activated flue gas damper integrated in the heat
exchanger of the Nova E H2O automatically controls the function. At a
sufficiently high flue gas temperature (approx. 150-200°C), the flue
gas damper closes automatically. Thus the flow of flue gas is routed
through the heat exchanger. If the flue gas temperature drops under this
temperature again, the flue gas damper opens. For better efficacy of the
heat exchanger, the Nova E H2O should be fired as uniformly as possible,
and frequent burn-down to the basic embers should be avoided in order
to obtain heat dissipation of the heat exchanger that is as uniform as
possible and to avoid low chimney temperatures.
• Double glazing (IR reflective surface): Through application of oxidic
coatings on the glass surface, infrared spectral components from the
combustion chamber are reflected to a great extent. These coatings
generate the interference colours (similar to a rainbow), the so-called IR
reflective surface. Through this colouration, the quality characteristic of
the „IR reflective surface“ is visible, i.e. recognisable. This colouration
cannot be removed.
• To operate the fireplace insert with nominal heat output, the following
prerequisites are necessary:
- Combustion must be operated with a closed door.
- Chimney draught: 12 Pa
- Wood: Dry beech wood (moisture < 18%)
- Wood feed quantity: 4.6 kg; distributed over four similar logs
- Air setting: Almost middle position, may need to be slightly
adapted depending on local conditions (see example). During
the combustion phase the air lever can be opened for several
minutes.
- At a combustion time of approx. 70 minutes the provided
output of the fireplace insert that is given off is approx. 14 kW.

5. CLEANING AND MAINTENANCE
For cleaning, also comply with the instructions in the operating manual
of the fireplace inserts. The instructions in this installation and operating
manual refer only to the cleaning of the heat exchanger of the Nova E H2O.
Bear in mind that through cleaning, contamination of the setup room and the
clothing worn can occur. We recommend that you protect the area around
the fireplace insert opening against contamination with foil or with a cloth.

GB 20
5.1 CLEANING THE HEAT EXCHANGER
The heat exchanger can only function at full efficiency if it is regularly
and properly cleaned and serviced. Cleaning must always be executed in a
cooled-down state! As the heat exchanger directly cools down the flue gases
of the Nova E H2O fireplace insert, and this unavoidably results in deposits
on the surfaces of the heat exchanger, these surfaces must be cleaned with
the provided brush on a regular basis. The frequency of cleaning depends
on several factors (use intensity, duration of burning, fuel, chimney draught,
etc.) and a general statement concerning frequency cannot be made.
Initially, we recommend cleaning approximately every 4 weeks. If heavy
contamination does not occur, the interval can be extended. The cleaning
intervals must be adapted to the local conditions. With the use of dry fire-
wood, a functional return flow temperature boost and compliance with our
recommendations, the cleaning intervals can be significantly extended.After
the heating season ends, thorough cleaning of all components is necessary.
The heat exchanger is always cleaned through the combustion chamber
of the fireplace insert. For this, the fireplace door must be opened and the
flame deflector plates (flame baffle plate) must be taken out of the combus-
tion chamber. Next, the thermally activated flue gas damper is removed
through the combustion chamber (see Fig. 6a). For this, the damper is tilted
slightly by the handle and taken out in a downwards direction. Clean the
thermal flue gas damper with a hand brush. Then the turbulators (bent
pieces of sheet metal in the flue gas pipes) are pulled downwards and out
into the combustion chamber with pliers. Subsequently, the heat exchanger
pipes and the middle channel, as well as the outer surfaces of the heat
exchanger, must be cleaned with the provided brush or a hand brush. Then
the deposits fall automatically into the combustion chamber and they can
be removed with standard aids (ash shovel, ash broom or an ash vacuum).
After cleaning, assembly is executed in the reverse sequence.
First, hook in the thermal flue gas damper (introduce diagonally from below
and place on the supports). Then slide in the turbulators (these do not
require a specific direction) and insert the flame baffle plates in such a
manner that the flue gas gap is on the rear of the device.

5.2 CLEANING THE DOUBLE GLAZING
The operator must only clean the double glazing on the combustion chamber
side and the setup room side in accordance with the instructions in the
operating manual. If the inner panes in the hollow space are contaminated,
then cleaning must only be executed by the customer service organisation
or a trained specialised company. In operation, a slight bright shimmer may
be seen between the glass panes. However these deposits do not constitute
grounds for complaint.
