LOHBERGER Heiz + Kochgeräte Technologie GmbH
1. IMPORTANT INFORMATION
-> Only burn the approved fuel listed in the chapter “Clean
Burning”.
-> Burning or inserting easily combustible or explosive materi-
als, such as empty spray cans and suchlike in the fire, as well
as storage of the same close to the fire is prohibited due to
risk of explosion.
-> When reheating , no wide or easily combustible clothing
should be worn.
-> Setting down of non heat resistant objects on the fire or
nearby is prohibited.
-> Do not lay washing on the fire to dry.
-> Stands for drying items of clothing or suchlike must be set
up at an adequate distance from the fire
– fire hazard!.
-> Working with easily combustible and explosive materials in
the same or adjoining room to the fire is prohibited when the
fire is on.
1.2. BEFORE SETTING UP
1.2.1. GROUND LOAD BEARING CAPACITY:
Before setting up, ensure that the supporting construction has
a load bearing capacity that will support the weight of the
fire. Commissioning details are shown on the sticker on the
Ceran area.
In the event that some of the instructions contained in this manu-
al are not clear, please contact the LOHBERGER expert staff.
LOHBERGER reserves the right to make changes to the specifi-
cations as well as to the technical and functional features of the
appliance at any time and without further notice.
1.1. GENERAL WARNING AND SAFETY INSTRUC-
TIONS
The general introductory warning information must be follo-
wed.
-> Read the whole of the manual thoroughly before commissi-
oning the fire.
-> Only approved transport aids with adequate load bearing
capacity must be used for transporting your fire.
-> Do not change the stove, except using original accessory
components supplied and tested by us or work performed by
our works service.
->Your fire is not suitable for use as a ladder or scaffold
-> Thermal energy is produced by burning fuel; this leads to
the surface of the fire, the doors, the door and operating
handles, the door glasses, the flue pipes and possibly the
front wall of the fire becoming very hot. Avoid touching these
parts without wearing the relevant protective clothing or using
the relevant means (cold hand).
-> Make children aware of the danger and keep them away
from the fire when in use.

1.2.2. FLUE PIPE CONNECTION
Flue pipes are a particular hazard source in respect of escape
of poisonous gas and fire hazard. Obtain the advice of an ap-
pointed specialist company in respect of laying and fitting the
pipes. When connecting the flue pipe to the chimney, in the
area of walls cladded using wood, please follow the relevant
fitting directives.
1.2.3.
You must follow the flue gas formation in the event of un-
favourable weather (atmospheric inversion) and the draught
conditions. If too little combustion air is added smoke can en-
ter your house or flue gases can escape. Additionally harmful
deposits can arise in the fire and in the chimney.
In the event that flue gas escapes let the fire go out and check
if all air inlet openings are free and the flue gas feeds and
the fire pipe are clean. In cases of doubt you must inform the
master chimney sweep, as a fault in the draught could be due
to the chimney.
1.3.
Before adding new fuel, push the embers together.
1.3.1.
Only use a suitable tool from our accessory range for pushing
the embers together, and ensure that no combustible material
falls out of the fire.
SAFETY CLEARANCES (Minimum clearances)
1. From non-combustible items
a > 400 mm b > 100 mm
2. From combustible items and supporting walls made from re-
inforced concrete construction
a > 800 mm b > 200 mm.
1.3.2.
Use the devices supplied with your fire, such as the protective
gloves or the cold hand to open the doors, as well as for ope-
rating the control elements.
1.3.3.
Design 1 fires (BA 1):
These fires must only be operated with the fire door closed.
1.3.4.
The fire door must only be opened for adding fuel and must
then be closed again, as this could otherwise lead to a danger
to other fires that are also connected to the chimney.
1.3.5.
When the fire is not in operation, the fire door must be kept
closed.
1.3.6.
When using wet fuel and if operation is throttled too much,
the chimney can soot up, i.e. easily combustible materials
such as soot and tar can be deposited and this can lead to
a chimney fire. Should this happen, close all air inlet slides
and flaps. Call the fire brigade and get yourself and all other
occupants to safety.
1.3.7.
The primary and/or secondary air supply must be open before
you open the combustion chamber door.
1.4. AIR FOR COMBUSTION
Basically, the appliance is dependent on indoor air, that me-
ans the air supply needed for combustion is extracted from
the room where the appliance is positioned - periodic venti-
lation, especially with very hermetically sealed building sys-
tems, is mandatory.
If there are additional heating units in the same room, the
ventilation openings must provide adequate air supply for
combustion to ensure proper operation of all appliances!
ATTENTION: The size of the fire door means that, particularly
when reheating blazing flames, the door must not be opened
abruptly, in order to prevent the flames from springing out.
Too low pressures in the room where the appliance is loca-
ted (e.g. caused by ventilation systems, extractor hoods etc.)
or in the pellets container (e.g. caused by pneumatic appli-
ances) are likely to impair the functioning of the fire place
and their safety (technique) and are therefore not permitted.
The operation of open heat systems depend on indoor air
in combination with ventilation, etc. is only under special
conditions allowed. Check with the manufacturer of your
ventilation system.

2. PACKAGING
Your first impression is important to us!
- The packaging for your new fire provides excellent protection
from damage. However damage to the fire and accessories can
occur during transport. The wood in the packaging has not been surface treated and
can therefore be burned in your fire. The box and the film (PE)
can be recycled without any problem.
-The packaging for your new fire in the main has no effect on
the environment.
Therefore please check your fire for damage and that all parts
are there on receipt! Report any defects to your fire dealer im-
mediately! When unpacking please ensure that the soap stone
panels are intact. The material scratches easily. Soap stones are
not covered by the warranty
3. TECHNICAL SPECIFICATION
The owner of the small heating system or the authorised person
for the small heating system must keep the technical documen-
tation in a safe place and present it to the local authority or the
chimney sweep.

Description
4. LIST OF COMPONENTS

Page 7
The following is important for clean burning:
1. THE FIREWOOD MUST BE DRY AND UNTREATED.
Recommended value < 15% rel. wood humidity.
Dry and well ventilated stored wood that has been stored for
2-3 years.
2. CORRECT FIREWOOD QUANTITY AND FIREWOOD SIZE
-> Too much firewood causes overheating.
This causes the material to burn too heavily and your fire will
produce poor flue gas values.
-> Too little firewood or too large billets have the effect that
the fire does not reach the optimum temperature. The flue gas
values are poor here.
-> The correct firewood quantity means:
for wood _ 1.8 kg (2 billet - 25 cm long) per layer (recommen-
ded value) at rated thermal output 6 kW.
At the smallest thermal output (3 kW) = 0.9 kg (2 billets - 25
cm long)
5.5. BURNING WOOD
Clean burning of wood corresponds to the same chemical
process as natural decay, i.e. that the CO2 (carbon dioxide)
released does not increase or contaminate the original CO2
content – household of the atmosphere.
5.6. HEATING IN THE TRANSITIONAL PERIOD
At temperatures above 15 °C there is a risk based on a low de-
livery pressure witch causes only a moderate fire. This results
in an increased formation of soot in the chimney flue of the
stove and in the chimney.
Increase the supply of primary air, stir up more often and put
frequent smaller pieces of wood on to prevent formation of
soot in transition time.
5. BRIEF HEATING INFORMATION
Note: Only wood and wood brickets must be burned in your
fire. Plastic, treated wood materials (e.g. chipboard), hard coal
or textiles must not be burned.
5.1. SUITABLE FUELS AND FUEL QUANTITIES
In principle your fire is suitable for burning dry billets. You
can also burn fuels such as wood brickets.
Only use dry fuel. The burning of waste of any kind, in par-
ticular plastics, damages your fire and the chimney, and is
prohibited by the Emissions Protection Ruling.
5.2. FUEL QUANTITIES
5.3. MAXIMUM FUEL QUANTITIES
Wood:
2 billets à approx. 0,9 kg
Wood brickets (broken):
2 off à approx. 0,9 kg
Your fire output is regulated via the air inlet slide. As your
fire output is also dependent on the chimney draught, you
must get used to the use of this slide according to your own
experience.
5.4. CLEAN BURNING
The challenges of the present day and age mean that eve-
ryone must act responsibly. One of most important matters
of concern is retaining our natural world. Our products are
developments that comply with the most recent state of the
art technology. This is an essential prerequisite for a clean,
efficient and perfect functioning of our fires
A fire is not a „waste incineration plant“. The warranty will be-
come null and void if rubbish or non-approved material, such
as plastic, treated wood etc. is burned. Further consequences
are damage or soiling of the fire and chimney as well as the
environment
The fire is equipped with flat firing due to the design. This me-
ans that only one layer of fuel may be placed on the existing
basic embers. Please note that when a larger quantity of fuel
is added, your fire will emit
a larger quantity of heat or will heat up more strongly than is
intended for the design. This can lead to damage to your fire.
The secondary air regulator, the primary air regulator and the
shaker grate handle may only be used with the shaker hook
enclosed.

6. INSTALLING THE FIRE
4. After the mortar has hardened, and after plastering and
painting , position the floor plate including the floor protec-
tion (carton).
5. The fire can now be lifted onto the floor plate carefully.
We recommend original flue pipes from the LOHBERGER flue
pipe range for professional connection. The connecting pi-
ece must not project into the chimney shaft! Seal the gap
between the flue pipe and wall lining using a ceramic seal.
6.1. CONNECTING THE FIRE
Proceed as follows when fitting a connection to a bricked
chimney:
1. Measure and draw in the chimney connection (taking a
possible floor plate thickness into account) as per the natural
dimension
2. Chisel out (drill) the holes in the wall
3. Brick in wall lining
Strong corrugated cardboard, carton, or an old carpet are ex-
cellently suited as an installation aid and an underlay. The fire
can also be pushed on this underlay.
Before first commissioning or after changing the location of the
fire, cleaning and service work, ensure that the flue plate, as
well as the wood stop (LIST OF COMPONENTS; page 6; Part 24
and 25) is in the correct position. When usinga flue pipe with
throttle valve, the throttle valve must be open.
Care must be taken with this fire that the flue draught reaches
at least the prescribed value (> 0.8 mbar). Should problems arise
here, please contact your master chimney sweep
Caution! Remove the sticker from the Ceran area before using
your fire for the first time.
Important: The Ceran area becomes very hot during use and
only cools down very slowly. There is an acute danger of bur-
ning up to one hour after fire has gone out!
First seal the wall lining using mineral wool insulation. After-
wards plaster using heat resistant cement mortar or equiva-
lent.
The fire must not be pushed along an unprotected floor.
The installation must comply with the respective safety and
construction regulations. Please contact your master chimney
sweep in this respect – he will be happy to give you informa-
tion
If you use a system chimney (e.g. glazed fireclay), we would
ask you to follow the manufacturer’s connection regulations
exactly.
7. OPERATION
7.1. STARTING THE FIRE
(Safety clearances; page 4)
In order to keep exhaust emissions as low as possible, we
would ask you to keep to the following starting instructions.
1. If the fire and chimney are still cold or if there is atmos-
pheric low pressure, then burning some paper at the start is
recommended, in order to “drive” the cold out of the fire and
chimney.
2. To start heating first lay untreated paper on the floor of the
combustion chamber, on top of that 0.5 kg soft wood chip and
1 kg wood (3 small billets).
Pull the shaker grate handle (Part II) out completely and open
the primary (Part I) and secondary air slide (Part III)
3. Now light the paper. Wait until the soft wood chips are
burning well. Close the shaker grate handle and the primary
air slide a few minutes later. Set the secondary air slide to the
ideal setting a few minutes later.
4. After this has burned, lay approx 1.6 kg wood (3 billets)
on the fire. Open the shaker grate handle and the primary
air slide until the wood is burning well (approx. 2 mins). The
secondary sir slide remains in the ideal setting. Proceed in the
same manner for each further layer.
5. The mineral parts of the wood (approx. 1%) remain on the
bottom of the combustion chamber as combustion residue.
This ash is – because it is a natural product - an excellent
fertiliser for all plants in the garden. However the ash should
be left to settle beforehand and doused with water.
Please do not use glossy paper or paper from magazines. It
does not burn well and the print colours produce very poiso-
nous substances in the flue gas.

Page 9
7.2. ASH DRAWER
The ash drawer must be emptied regularly to prevent exces-
sive heating of the fire grid OPERATING THE SHAKER GRATE
THE FIRE PAINT ONLY HARDENS PROPERLY AFTER HEATING UP
DURING USE.
- Do not touch the surface during heating. It is still soft.
- Our paints are completely harmless in accordance with the
TÜV-certificate; there is no danger to health. In spite of that
we recommend that the house is well ventilated several times
after first heating.
-Heat the fire up well – this will reduce the hardening time.
- Hardening of the surface is complete after several proper
periods of heating.
All details on the nature of the fire wood and correct heating
can be found in Chapter 5.
Never heat the fire with the ash drawer open > danger of
overheating >loss of warranty.
Caution: Embers could remain in the ash. Only fill the ash
into non-flammable containers and do not put the ash onto
flammable surfaces.
7.3. OPERATING THE SHAKER GRATE
The ash is moved from the fire into the ash drawer (part 22)
by moving the Riddling grate actuator (Part 13). This frees up
room for the primary feed air that is required for the heating
phase in the fire.
It is not necessary to operate the shaker grate during heating.
7.4. SLIDE SETTING AT RATED THERMAL
OUTPUT
Fuel Wood/Wood Brickets
Primary air closed
Secondary air 1/3 open
Shaker grate closed
The position „Primary air completely open“ may only be used
as a starting position.
As your fire output is also dependent on the chimney draught
and the weather conditions, you must get used to the use of
this secondary control slide according to your own experience.
8. FITTING OPTIONS
8.1. MAKING AN EXTERNAL COMBUSTION AIR
FEED
-> Dismantle the rear wall following the instructions: Take off
the Ceran cooking surface (pos. 30). Then loosen the four
screws of the cast iron cover (pos. 29) and lift it. Now pull the
rear wall from the aluminium profiles upwards (pos. 14).
-> Cut out the pre-cut, round section from the rear wall (pos.
31) (hack saw blade).
Tighten the supply air inlet pipe (optional, on order) by means
of the supplied screws and remount the rear wall.
-> Connect a non-flammable pipe (e.g. steel spiral pipe) to
the supply air inlet pipe and fasten it with a hose-clamp (not
included in the delivery!).
-> To ensure sufficient supply of air, the pipe should not ex-
ceed a length of 4 m and have no bends.
-> If the pipe runs to the outside, the pipe end must have a
vertical 90°bend downwards or be protected against wind.

Page 10
9. MAINTENANCE AND CLEANING
9.4. CONVECTION AIR OPENINGS
Regularly clean dust deposit from the convection air openings.
The fire should be cleaned thoroughly before the start of the
new heating season, in order to prevent strong odours.
9.5. CLEANING THE FLUE GAS CHANNELS
(1x annually)
-> Removing the flue pipes
-> Brush off any soot and dust deposits in the fire and in the
flue pipes and vacuum.
-> Check the seals on the fire door or the ash drawer before
the beginning and end of the heating period. Should they be
damaged or excessively worn, then please order the relevant
replacement.
9.1. GENERAL MAINTENANCE
Your Cook ME has been designed by our development team
with minimal maintenance in mind and for a very long service
life. Certain cleaning activities and checkin the seals are howe-
ver necessary from time to time. The time periods between the
inspection intervals are above all dependent on the fire wood
quantity used and the frequency of use.
9.2. ONCE MORE
Only use wood that has been stored properly and is dry and
untreated. Feed the correct quantity of wood into the fire.
9.3. FINISH - CONDITION AND CLEANING
The door glass can be cleaned using glass cleaner. The glass
cleaner can be obtained from your specialist fire dealer.
Should the glass become heavily sooted the possible cause
could be damp wood.
The fire finish is highly refractory and must only be cleaned
using a cloth (damp if necessary). Only use original paint for
touch up work, this is available from your specialist dealer as
an accessory.
Under no circumstances must the paint be cleaned before
heating for the first time!
All maintenance and cleaning work must only be carried out
when the fire is completely cooled down.
All maintenance and cleaning work must only be carried out
when the fire is completely cooled down.
Only intact seals guarantee the perfect function of your fire.
