Please note that any appliance will only work properly if cor-
rectly used and cared for. Prerequisite for high reliability, eco-
nomical operation, low-pollution combustion and long service
life is the adherence to some important rules:
•Do not change the stove, except using original accessory
components supplied and tested by us or work performed
by our works service.
•Install only original spare parts, available from your dealer
or from us direct.
•Expert installation by an expert taking into account the regu-
lations and provisions applicable at the place of installation.
Adhering to the information in the installation instructions
and user manual and consulting the responsible chimney
sweeper to assess building conditions or technical aspects.
•Proper operation by adhering to the information in the in-
stallation instructions and user manual and the instructions
concerning safety and environmental protection.
•Correct fuel by using environmentally compatible high-qual-
ity dry types. (see “Fuels” Page 14)
•Maintenance and care at regular intervals. If these are omit-
ted, malfunctioning, faults and damages will automatically
accumulate and result in problems and costs. Renew or re-
place wear parts (e.g. seals), parts exposed to high tem-
perature (refractory, castings) or broken stove components
as quickly as possible.
•Regularly clean the stove, the heating gas draughts, the
connecting piece and the chimney.
•Heat with low output during the first 2-3 days. This dries
through the stove refractory slowly and lasts much longer!
When heating during the initial days it is possible for the
refractory lining to crack. However, this does not impair the
heating function.
•Models with heating compartment – the range must only be
operated with a return valve (thermal valve, motor control-
led mixer valve). Damage caused by a missing return valve
are excluded from the guarantee!
•Open heating damper only for initial heating – Always keep
heating and ash doors closed. Avoid overheating the stove
(e.g. red-hot steel cooking plate). Damages caused by such
are excluded from the warranty!
•Adequate supply of fresh air to the room of installation
during heating! At least 0.8 times air change per hour must
be ensured through permanent and safe room ventilation.
With tightly sealing windows and doors or when other ap-
pliances such as extractor hoods, electric driers, fans etc.
use air from the room in which the stove is installed, the
supply of combustion air (fresh air) from the outside might
be required.
•Correct procedure in the event of chimney fires:
Never attempt to extinguish the chimney fire by applying wa-
ter. The suddenly developing steam pressure is so high that
the chimney could burst.
IMPORTANT INFORMATION
Call the Fire Brigade via the emergency phone number
The chimney may get blocked when the stove is heated up
again after a prolonged operating interruption. Before restarting
the stove, have the chimney inspected by a specialist (chimney
sweeper).
The slow-burning stoves of series LIGNAITHERM are built according to the current state of the art and comply with the requirements of
the following standards for wood as fuel:
the European standard EN 303 T5E, ÖNORM M 7550, the German industrial standards DIN 18880 and DIN 18882, DIN Plus, and BIM-
SCH.
The following requirements are met:
• Agreement of the Provinces between Federation and Provinces according to BVG Art. 15a B-VG (Federal Constitution Act) on protective
measures concerning minor furnaces and the saving of energy dated June 1995.
• Special provisions in terms of efficiency and pollutant emission applicable in Regensburg and Stuttgart.
GENERAL INFORMATION
Before installaing and starting up the appliance you have to
read this documentation carefully.
Nonobservance may lead to a loss of warranty!
Please keep the manual in a safe place. If it is lost so we will
be glad to to send you a new one. Here you will find important
information concerning security, use, care and maintenance of
the appliance, this ensures a long service life of your stove. If

SAFETY INSTRUCTIONS
During installation and operation
• Use the user manual when installing the stove and pay at-
tention to the individual points.
• Consider the safety distances when installing the stove.
• Check the tightness of the flue pipe connection.
• Inspect the stove for damages (e.g. glass items).
• Never charge with more wood than is necessary for the rat-
ed heating output (approximately 1-2 kg).
• For adding fuel, slowly open the door, allow the flue gases
to disappear and avoid flue gases escaping into the room.
• Please remember that some components on the stove (flue
gas pipe, filling door etc.) get hot during heating and con-
stitute a burning hazard. Ensure that small children in par-
ticular are not exposed to this danger!
• Do not shut off the stove during heating as this could pose
a detonation hazard.
Attention! Playing children!
Keep in mind that some components on the stove (flue gas
pipe, handles, filling door, etc.) become hot and present a
serious danger of being burnt. Please check out that children
follow a safe distance during the heating.
Cooking surface
• Overheated grease and oil can ignite spontaneously, pre-
pare food with grease and oil such as potato chips only
under supervision. Never extinguish ignited grease and oil
using water! Put on the lid and pull the pot from the hot
cooking surface.
• If the glass ceramic cooking field is damaged or broken,
switch off the appliance.
• Do not place aluminium foil or plastic on the cooking sur-
face.
• Do not place combustible or ignitable objects on the cook-
ing surface which could constitute a danger when the ap-
pliance is started.
Roasting oven
• There is a risk of burning when working in the hot roasting
oven! Use oven cloths, heatproof gloves or similar.
• Do not store items in the roasting oven that could pose a
danger when the appliance is started.
• Careful when opening the roasting oven door. Do not imme-
diately bend over the opened roasting oven door. A rush of
hot air or even steam will escape through the open door.
• Always close the roasting oven door completely when pre-
paring food inside the roasting oven.
Before lifting the stove from the transport pallet, carry out the
following operations:
1. Remove fuel drawer
2. Remove transport locks
3. If available, attach transport belts in the 4 mounting facili-
ties in the base area.
Transport and appliance installation:
ÖTransport the appliance to the place of installation. Remove
transport belts and the reinforcing angel. (Transport belts
are available as accessories)
ÖAdjust stove frame overhang and stove height (see appli-
ance height and stove frame on Page 12).
ÖMake flue gas connection
ÖCarefully place the stove right up against the wall.
With levelling feet screwed out, move the stove carefully so as
not to damage the appliance.

APPLIANCE DESCRIPTION
Firing chamber, combustion chamber F1, F2
Depending on the required output, LOHBERGER offers you two
combustion chambers. Thanks to the proven JETIFIRE system
and separately controlled primary air and secondary air, both
types meet the stringent Austrian regulations established in
the “Agreement between Federation and the Provinces ac-
cording to Art. 15a B-VG (Federal Constitution Act) (concerning
the saving of energy”, the European standard EN 303 T5E,
ÖNORM M 7550, the German industrial standards DIN 18880
and DIN 18882, DIN Plus, BIMSCH, as well as the special regu-
lations in terms of efficiency and pollutant emission applica-
ble in Regensburg and Stuttgart.
Roasting oven B1, B2
All roasting ovens are equipped with baking sheet and grid,
the lateral baking sheet carriers have 4 slide-in levels. The
roasting oven inside is fully enamelled and therefore easy to
clean. (Cleaning instructions on Page 18).
The hot airflow gently circulates in the roasting oven. The
convoluted route of the flue gas ducting guarantees even tem-
perature distribution on the stove plate (steel or CERAN®)
and in the roasting oven, likewise the continuous heat radia-
tion to the surroundings.
Roasting ovens are available in two sizes (baking sheet di-
mensions: 30 x 40 cm, 35 x 40 cm).
Preheat the roasting oven for roasting and baking to achieve
even temperature distribution.
A lively fire is necessary to maintain a roasting oven tem-
perature of approximately 250 ºC. Dry beech wood is highly
suitable for this purpose.
ROASTING OVEN THERMOMETER
The thermometer in the inspection glass of the roasting oven
door has a display range of 0 – 400 ºC. The temperature mark-
ings are reference values for baking and roasting and may
differ slightly from case to case.
Substructure with fuel drawer
The LOHBERGER fuel drawer is famous for its stability – the
new feature is that it has become even more spacious since it
now fully utilises the space of the stove base as well.
Stove frame (adjustable in the case of CLAS-
SIC)
In the case of CLASSIC the stove frame is adjustably mounted
to the appliance. This means that you can terminate the stove
frame flush with the working top as well as the appliance front
flush with the kitchen front when installing the appliance in a
built-in kitchen. Maximum protrusion is 3 cm.
Stove plate
Choose between a flat-ground steel plate in nostalgic style
or, if you wish to enjoy the play of the flames, an original
CERAN® cooking field.
Glass ceramic cooking surfaces by SCHOTT of Mainz are ex-
tremely temperature-resistant and withstand even abrupt tem-
perature shocks up to 750 °C.
CERAN® is insensitive to normal mechanical loads in the
kitchen. The four millimetre thick glass ceramic is also highly
heat-permeable. It allows radiation heat to pass through al-
most without loss, but hardly dissipates any heat laterally.
CERAN® cooking fields are easy to clean (please observe the
relevant information on Page 3 of the cleaning instructions
enclosed with the cooking field!) and display the flames.
Sidewall
Depending on the requirement your appliance is equipped
with 1 (2) standard sidewall (walls) and/or 1 (2) fire protection-
tested sidewall (walls).
An insulating element for installation between stove and com-
bustible attachments (kitchen furniture) required (and tested)
in accordance with the Fire Police is included in the fire protec-
tion sidewall. The appliance width is increased by 50 mm per
fire protection sidewall compared with the standard appliance
when using the fire protection side.
Your roasting oven can reach temperatures of up to 400 °C!
Please do not use any (usually too soft) aluminium pots on
your CERAN® cooking field! Since the glass ceramic is consider-
ably harder than most aluminium alloys, unsightly streaks may
form on the glass surface – which can hardly be removed once
burnt in.

When installing the stove, observe the regulations and provi-
sions of the building authorities and fire police applicable at
the place of installation.
• Ensure the stove is positioned
horizontally and without vibra-
tion.
• Keep adequate distance from
combustible items (wood pan-
elling, furniture, curtains, etc.)
around the stove. The walls in
the area of the stove must be
rendered fireproof extending up
the full height of the walls and covering a width of at least
50 cm to either side or to the front beyond the fireplace.
• The safety distance with items to be protected (e.g. combus-
tible walls, walls with combustible components, suspended
kitchen cupboards and carrying walls made of reinforced
concrete) is:
• When attached to combustible materials or installed in a
built-in kitchen or attachment to an electric stove or any
other appliance, a fire protection sidewall (+50 mm) must
be provided. Excluded from this is the installation version of
the CLASSIC series. These appliances are already equipped
with the two-sided fire protection and can be directly inte-
grated in the built-in kitchen. Maximum height of the at-
tached installation items in this case corresponds to the
stove height (standard stove 85 cm).
• With a combustible floor (wood, plastic, wall to wall car-
pet,...) a floor plate made of steel, copper or another non-
combustible material must be used. This surface must pro-
trude the stove outline by at least 5 cm, on the operating
side by at least 30 cm.
• Overhead installations: Maintain a minimum distance of 75
cm and ensure adequate rear ventilation for the suspension
boxes to avoid heat being trapped.
• When installing the flue gas pipe, adhere to the following
minimum distances to combustible building materials: wall
distance 20 cm, ceiling distance 40 cm.
With this type of questions it is imperative to consult your
responsible chimney sweeper.

Stove frame (only CLASSIC)
With CLASSIC the store frame is mounted adjustably on the
appliance. This means that you can install the appliance in a
built-in kitchen with the stove frame flush with the working
top and the kitchen front. Maximum protrusion is 3 cm.
• Pull out operating handles for grate shaker and heating
damper. (Page 6, Items 4+9)
• Loosen the Allen screws of the operating handles (bottom)
only slightly and turn out to the desired stove frame protru-
sion (e.g. stove frame protrusion = 2 cm Öturn out the
operating handles by 2 cm)
• Tighten the Allen screws of the operating handles. When do-
ing so ensure the complete closing of the heating damper
with the operating handle pushed in!
• Remove cooking plate(s) and loosen the stove frame mount-
ing screws (10 pieces).
• Correctly position stove frame, retighten stove frame mount-
ing screws (10 pieces).
• Fit cooking plate(s).
Appliance height
The 4 levelling feet allow offsetting irregularities in the floor
and adjustment to other appliances or kitchen attachments.
To do so, screw out the 4 adjusting screws using the supplied
universal wrench.
Flue drawer panel (only installation version)
Fuel drawer panel can be chosen from 9,3 – 25,3 cm (de-
pendent on the actual appliance height and the desired floor
clearance).
Example:
Base panel (only installation version)
Base panel height can be chosen from 17 – 24 cm (dependent
on the actual appliance height).
The base panel (wood) is attached to the fuel drawer with two
straps (2 screws each). Loosen the screws, adjust the desired
base depth (5 – 6,5 cm) and retighten.

Flue gas connection - conversion
All appliances are supplied for rear connection as standard
but the appliances are prepared for lateral connection at the
factory. However you will require a new sidewall with flue pipe
connection for subsequent conversion and returning the “old”
sidewall is unfortunately not possible.
Subsequent conversion from lateral to rear is also possible.
The two covers required are available as “lateral flue pipe
conversion kit”.
Subsequent top connection is only possible with steel stove
plates – since t Central heating insert (optional equipment)
Trouble free and economical operation is guaranteed if all fac-
tors required for sound combustion are present:
The chimney
• Design and condition to suit the regulations applicable at
the place of installation.
• Prior to connection, inspect for possible faults and defects.
• Effective chimney height of 5 m (from cooking plate to the
chimney outlet). If the height is less, the stove must be
equipped with an at least 1 m long vertical terminating flue
gas pipe. Connection to a chimney with less than 4 m effec-
tive height is not advisable.
• Even, square or round internal cross section, insulated to
prevent cooling.
• Chimneys made of ready-made components are preferable.
• Assessment of the entire flue gas system according to DIN
4705 Parts 1 and 2, with multiple chimney connection, ac-
cording to Part 3.
Should you have such questions it is imperative to consult the
responsible chimney sweeper.
Connection stove - chimney
The flue gas pipe is the connection between stove and chim-
ney. During its installation it is also important to observe the
following information:
• The diameter of the flue gas pipe must not be reduced to-
wards the chimney.
• The pipe must not protrude into the chimney.
• Vertically installed, uninsulated flue gas pipes must not be
longer than 125 cm.
• Horizontal flue gas pipe sections must not be longer than
100 cm.The flue gas pipe must not drop towards the chim-
ney but rise slightly.
• The connection between stove and chimney must be stable
and tight. Especially the installation in the brickwork of the
chimney must be performed permanently and tight.
The necessary delivery pressure (“Chimney
draught”)
The vacuum prevailing in your chimney measured in “mbar” is
a “dimension” for the efficiency of your chimney. The delivery
pressure required for your stove is shown in the Table “Techni-
cal data” on Page 9 and on the nameplate of the stove.
With new chimneys you can trust the details (calculations)
of the manufacturer with older chimneys, request the help of
your chimney sweeper.
ÖInsufficient delivery pressure would result in incomplete
combustion and consequently in increased soot and tar
formation in the stove and in the chimney.
ÖExcessive delivery pressure on the other hand would ac-
celerate combustion, result in high flue gas temperatures
(damaging the appliance) and hugely increase fuel con-
sumption.

preparing water for domestic use! The safety devices must
still be accessible after the installation. The drain/outlet must
be visible for checking the proper functioning of the thermal
discharge safety valve, therefore use the drain funnel!
A function check of the thermal discharge safety valve must be
carried out at least once a year. To do this, the red cap must
be pressed against the valve, and water must flow into the
drain funnel. Should the thermal discharge safety valve drip,
then the seal and valve seat must be cleaned. Safety devices
must also be checked for calcification at least once a year.

VIEW FROM THE REAR:
CENTRAL HEATING INSERT (OPTIONAL EQUIPMENT)
The stoves type LM 50, LC 75B und LC 80, that means appli-
ances with combustion room capacity F2, can be equipped
with a central heating element (type designation -Z).
Heating installation /connection
The boiler is suitable and approved as a heat generator for
warm water heating installations with a flow temperature up
to 95C° and a permissible excess operating pressure of 3 bar.
The following standards are to be observed when installing
the stove:
Open units: ÖNORM B 8130 or DIN 4751 part 1
Closed units: ÖNORM B 8131 or DIN 4751 part 2
For “closed units” we recommend using our valve cabinet.
This cabinet, which is only 30 cm wide, contains a return flow
increase as well as safety devices such as bleeder valve and
safety valve.
Required for closed units:
• A closed expansion vessel
• A thermometer and a manometer
• To avoid overheating an automatically operating device to
release heat. Connection of the built-in safety battery (heat
exchanger) with thermal discharge safety valve. The connec-
tion can be found on the back of the stove (1/2" outside
screw thread), when fitting the manufacturer’s instructions
are to be followed.
• A safety valve at the highest point of the stove or on a con-
nected pipe (non-closable).
All safety valves used for the installation must be certified
(reference letter "H" in the component certification register!),
their flow rate must correspond to the highest nominal output
of the boiler.
Further points to be observed:
ÖHeating room guidelines,
ÖNational building regulations,
ÖLocal building regulations,
ÖCommercial and fire police regulations,
ÖEnvironmental protection regulations,
ÖRegulations of the local electric utility company.
A trial run must be carried out after completion of the connect-
ing work during which all control and security devices are to
be adjusted and checked for proper functioning. The assembly,
installation, fine-tuning and initial operation with the trial run
must be carried out according to the installation and opera-
tion instructions by a qualified heating professional! Only then
can it be guaranteed that the appliance functions flawlessly.
If any damage occurs through omission of any of the above
points, all warranty claims become null and void. Avoid flow
temperatures of less than 60 °C because of the subsequently
occurring condensation in the boiler. Please note the following
point return flow increase!

The heat exchanger serves to protect the boiler from over-
heating during a pump standstill and may not be used for

Return flow increase as protection against corrosion
Too low operating temperatures, that means flow and return temperatures that are too low, have a significant detrimental influence
on the service life of the boiler. When the water dew point is not attained, condensation water, with more or less aggressive chemical
components that accelerate corrosion, forms on the surface of the heating boiler. Temperatures falling below the dew point primarily
occurs in low-temperature heating installations (return temperatures down to below 25 °C), in installations without a mixer, in the case
of extreme light load operation during changes in season and in constant light load operation caused by boilers that are dimensioned
too large.
Therefore care must be taken that the return flow temperature at the return flow connecting piece of the appliance must be at least
55 °C. In the ideal case the return flow temperature at the boiler inflow is around 60 °C. The return flow increase (the pump for the
return flow increase must be fitted in the return flow) should be installed as close as possible to the boiler so as to ensure that the
mixing water temperature at the mixing valve is equivalent to the return flow temperature at the boiler.

STOVE OPERATION
Heating damper
To facilitate initial heating, all LOHBERGER stoves are equipped
with a heating damper. Opening the damper opens a direct
route from the fire chamber to the chimney. Consequently the
flue gases need not take the “long” route through the roasting
oven, but enter the chimney while still hot, in this way estab-
lishing a chimney draught very rapidly. Once the chimney has
established sufficient draught and the initial heating phase is
completed, close the heating damper again.
It is integrated in the stove bar on the side opposite to the fire
chamber. Pulled out is open; pushed in is closed
Grate shaker
The suspension-mounted and consequently easily operated
grate shaker serves to remove the ash from the grate. The
shaker is integrated in the stove bar on the combustion cham-
ber side. Ash is best removed whenever charging fuel. Regu-
larly empty the ash drawer, clean the grate thoroughly once
or twice per week.
Ash door protection
A latch, ensuring that the ash door
can only be opened together with
the heating door, is provided on the
ash door inside. This serves to pre-
vent inadvertent overheating of the
stove.
Air control
To ensure that you have many years of pleasure with your
stove, all appliances are equipped with an automatic tem-
perature limiter as standard. This serves to “limit” the com-
bustion air flow rate. However, this has only a limited effect
on the output. It is definitely not suitable for compensating
excessive fuel charges. A certain amount of fuel will require
a certain amount of oxygen for optimum combustion. If the
wood is supplied with a lesser quantity of air than is required
for clean and efficient combustion, less energy is generated in
the appliance (the appliance largely protected from overheat-
ing) – the unutilised “wood gas” however escapes through
the chimney; the result: low efficiency and high environmental
load. Remedy: charge the stove only up to the recommended
fuel level.
The air entering the fire chamber from below through the grate
is responsible for the output since it generates the basic heat
resulting in “wood gasification”. Rule of thumb: lots of air
from below means lots of combustible wood gas (controllable
with the help of the lower of the two rotary knobs on the
front). This wood gas is cleanly and efficiently burnt at ap-
proximately 950 ºC by means of preheated secondary air (JETI-
FIRE combustion technology). The secondary air (the upper of
the two rotary knobs) enters the combustion chamber through
openings in the fire compartment rear wall and from below
and above along the fire compartment door (or view window)
over the fuel into the combustion chamber.
The exact mixing of the wood gas with hot secondary air en-
sures optimum combustion – and connected with this, excel-
lent fuel utilisation. The environment will be grateful!
Primary air control
The supply of the primary air
required for the combustion is
controlled with the lower rotary
knob on the ash door. This de-
termines the burning speed and
consequently the heat output of
the stove. In position “0” the
controller is closed, no combus-
tion air is supplied. In position
“1” minimum air supply is pro-
vided, this must be selected for
slow-burning operation. Turning
the rotary knob to position “3”
means maximum air supply, nec-
essary especially during the ini-
tial heating phase.
ÖAir settings see Table Page 14.
Secondary air control
The supply of secondary air
(combustion air flowing over
the fuel from the top) serves to
achieve low-pollution combus-
tion matched to the fuel used.
The secondary air is controlled
with the upper of the two ro-
tary knobs in the ash door. The
markings “0” – “6” are visible
on the knob. Moving the lever
in the direction of “0” reduc-
es the incoming secondary air
flow, while it is increased in the
direction of “6”.
ÖAir settings see Table Page
14.
The heating damper must only remain open during the initial
heating phase. If the heating damper remains open during heat-
ing operation, this will overheat the stove and damage stove
components. A heating damper maintained in the open position
will also increase fuel consumption.

Adding fuel
• After the initial heating phase, add more fuel as per Table
(see air settings).
• Set primary air controller to stage 1.
• Set secondary air controller depending on output required.
When adding fuel we recommend:
1. Short intervals (every 30 – 50 minutes)
2. 2 – 3 small wood billets (corresponding to 1 - 2 kg)
Air settings
The recommended air settings (after operating temperature
has been reached) and filling quantities at rated heat output
are specified in the following table (reference values accord-
ing to DIN).
The specified air settings are reference values. Establish the air damper position
to suit the heat requirement of the room by trial and error.
WOOD BRIQUETTES
The water content of wood briquettes is very low, combustion
is very rapid.
Calorific value of wood briquettes: ~4.4 kWh/ kg
Unsuitable fuels
Moist wood, bark waste, sawdust, fine wood chips.
Brushwood, wood wool, wood chips. Use only very small
amounts of paper for lighting.
Burning such fuels generates high levels of pollutant emission,
a lot of ash while the calorific value is very low.
Impermissible fuels
Surface-treated wood (veneered, painted, impregnated, etc.),
chipboard wood, all types of waste (packaging waste), plas-
tics, newspapers, rubber, leather, textiles, etc.
Burning such materials will greatly pollute the environment
and is prohibited by the legislator.
It can also damage the stove and chimney.
Close the heating damper after approximately 15 minutes.

WOOD
Sustainable, local energy medium. During photosynthesis, wa-
ter, soil minerals and carbon dioxide (CO2) are converted into
wood with the help of solar energy. During the combustion,
this solar energy, water, CO2 and the minerals (ash) are liber-
ated again. Wood is stored solar energy! Wood is not affected
by crises, it creates local jobs.
Billet wood should have a maximum water content of ap-
proximately 30 % of the dried weight, be approximately 1/3 m
long and be chopped small. In this way the billets are ignited
rapidly, producing a better heat output than larger wood bil-
lets for the same amount of wood. Undercover in the open,
fir, pine or alder wood should be stored a good 2 years, hard
wood even 3 years.
CALORIFIC VALUE
The significance of the water content of wood on the calorific
value is shown in the following table:
Any warranty will be void in this case!

After completion of the installation and connection work and
prior to the initial start-up, a few operations must be per-
formed:
• Steel cooking plate: ensure a 2 mm gap all round the stove
frame to prevent a discoloration of the stainless stove frame
when heating!
• Open heating and ash door, pull out ash drawer and remove
all-purpose wrench.
• Wipe off the corrosion protection applied to the steel cook-
ing plate (see Page 19)
Once you have made yourself familiar with the operation of
the stove, the initial start-up can commence.
Initial heating
• Open heating damper, set controller for primary air (bottom)
to stage 2 and controller for secondary air to stage 6.
• Open heating door
• Place 2 – 3 wood spills or wood wool on the grate
• Stack 2 wood billets on top. Put some wood wool on top,
ignite it and subsequently place a medium-sized wood bil-
let on top.
• Close heating door and allow wood to develop a lively fire.

Summer /Winter use
(Only for stoves with central heating insert)
SUMMER USE:
• Remove baffle plate:
• Insert angle plate for summer use:
WINTER USE:
• Insert baffle plate
• Without the baffle plate the water heating output is low-
er, however the temperature for cooking and baking is in-
creased.
• Remove angle plate for summer use.
Heating
When only embers are present on the grate, place new fuel
evenly distributed on the entire grate. To do so, evenly level
the bed of embers on the grate and new fuel can be added
thereafter.
Uninterrupted firing should not be attempted with wood.
Fuel filling level
Please note that your stove should only be filled up to the
secondary air openings in the fire chamber rear wall and not
above the air openings of the upright grate behind the fire
chamber door, as this would interrupt the air flow in the com-
bustion chamber. On stoves with view windows this will result
in the glass sooting-up and becoming cloudy (ceramisizing, no
warranty!), and always in incomplete and consequently inef-
ficient combustion with all appliances; low efficiency.
Cooking
Cooking is best done on a hot but not red-hot stove plate.
Overheating means wasting of fuel.
The highest stove plate temperature is present in the heating
area (above the JETIFIRE flame concentration plate), this area
is therefore ideally suited for rapid initial cooking. The edge
zones with lower temperatures can be used for slow cooking
or keeping warm. You are best advised to use pots with thick,
level base and fitting lid.
Baking and roasting
Baking and roasting requires evenly distributed heat. In order
to achieve this uniformity and sufficiently high temperature,
the roasting oven must be preheated to suit the particular
foodstuff with the heating damper closed. Once the stove is
heated to the desired temperature, place the food in the oven.
However, do not allow intense and full embers to develop,
rather keep adding fuel in small quantities. Place high cake
tins on the roasting grill on the lower slide-in support of the
roasting oven. Bake all cakes in baking tins at medium heat
(180-200 °C). A baking sheet with a flat cake or small confec-
tionary items can be placed on both slide-in supports. A slight-
ly higher baking heat (200-220°C) is recommended here.
Considerably higher temperatures are required for roasting.
Preheating is indispensable for this purpose.
The heat output delivered to the hot water system will be re-
duced, however, it will not be stopped completely!
Thus even for summer use make sure that excess hot water is
discharged properly.
In order to lower the heat output for summer use (especially for
cooking and baking) the appliance is equipped with a remov-
able baffle plate.

MAINTENANCE AND CARE
Regular maintenance and care or cleaning of the stove, the
heating gas draughts and the connection piece as well as the
chimney are particularly important for the operational safety,
economy and value retention of the stove.
Thorough cleaning should be performed after each heating
period and after prolonged operation interruptions (see Im-
portant notes, Page 4). When used frequently or when using
inferior fuels, correspondingly more often!
• Remove cooking plate and clean, especially at the bottom!
With glass ceramic cooking plates, clean the bottom with a
dusting brush, with steel cooking plates use a wire brush.
• Remove grate and brush off. Clear out clogged grate slits.
• Remove flue gas pipe(s) and sweep.
• Scrape combustion chamber walls and flue gas shaft with
the ash pusher.
• Brush heating damper and mounting and check operation.
• Remove ash drawer and empty. Sweep ash drawer space.
• Scrape the heating gas draughts accessible after removing
the cleaning cover using the ash pusher.
• Check cooking plate and cleaning cover sealing cords, re-
new if required.
• Clear the secondary air slits in the heating door protection
plate using a wire brush.
• When cleaning the chrome-plated anodised or enamelled
surfaces, use only mild (non-alkali) cleaning agents and
non-abrasive cleaning equipment. The same applies to the
cleaning of the roasting oven.
• When reinstalling the various stove components (flue gas
pipe, cooking plate, grate, cleaning cover, ash drawer) en-
sure they are correctly positioned and function as required
and that there are no leaks.
• When placing the cooking plate ensure a 2 mm wide gap to
the stove frame all round!
Grate
The ash is quite easily removed from the grate using the grate
shaker. However if the air slits are severely clogged by slag,
crusts or other combustion residue, completely remove the
grate and clean.
To do so, open the heating door and pull the grate through
the heating door.
After cleaning, slide the grate through the heating door against
the rear refractory brick, lower at the back and push back
against the stop once more.
Operate grate shaker.
Cleaning opening
The cleaning door panel is engaged in a ball snap-action latch
and pivots out. The cleaning cover situated behind is secured
to the stove front with 2 knurled nuts and can be removed
for cleaning the heating draughts. Before reinstalling, check
the sealing cord on the cleaning cover for leaks and replace
if required.
Roasting oven door
The roasting oven door can be completely removed. This is an
advantage for the thorough cleaning of the roasting oven.
To cool down the roasting oven, the roasting oven door can be
fixed in an approximately 70° position.
DISCONNECTING THE ROASTING OVEN DOOR
ÖFully open the roasting
oven door.
ÖFold the clips in the door
hinges forward.
ÖHold the roasting oven door on the
sides using both hands.
ÖLightly lift the door and pull the

Stoves with steel cooking plate
INFORMATION CONCERNING THE CARE AND PRESERVA-
TION OF THE STEEL COOKING PLATE
Stoves with a brightly ground steel cooking plate had the sur-
face oiled prior to packing to protect from corrosion.
INITIAL HEATING
Before initial start-up, wipe off the corrosion protection ap-
plied to the cooking plate. However, open the window dur-
ing initial heating since the applied corrosion protection will
develop unpleasant but harmless fumes and smell for a short
time.
In addition, the steel cooking plate will discolour when ex-
posed to heat from the hottest point towards the edge of the
plate which is typical for steel. This discoloration will become
more and more even with every additional start-up!
CLEANING
The steel cooking plate is best cleaned while still hot.
Conventional powdery or liquid scouring agents can be used
for cleaning. Stubborn crusts should be removed with the
cleaning fleece enclosed with the stove (Caution: note grind-
ing direction of the steel stove plate; not suitable for glass
ceramic, enamel, plastic)
Follow-up by wiping the cooking plate with a moist cloth and
allow to dry. Of course, this is done quickest while the stove
is still warm. After this, lightly coat with non-acidic oil (e.g.
sewing machine oil, gun oil) or some margarine.
Do not leave any pots or pans standing on the cold cooking
plate. “Rust rims” would form that are difficult to remove!
PRESERVATION
If the stove is to be left unutilised for an extended period of
time it is advisable to coat the cooking plate with non-acidic
oil or some margarine after cleaning. Of course, the cooking
plate must be wiped again prior to subsequent use!
If you follow these instructions you will avoid rust and stains
on the cooking plate and the stove retains its cared-for ap-
pearance.
Ensure that the expansion joints of the steel cooking plate
are always free of encrustation to facilitate the expansion of
the plate under the effect of heat. Burnt-in remains of food or
slag pieces in the joints can result in the steel cooking plate
being distorted.

ASSEMBLY
During assembly the bevelled edge of the reinstalled viewing
window pane must be on the side of the fixed pane. The bev-
elled edge indicates the side with a special IR coating which
reduces heat radiation through the viewing window.
Reinstall the complete glazing unit in reverse order to the
disassembly.
Do not use harsh or abrasive cleaning materials as this will dam-
age the surface coating (IR coating).
Cleaning the glass viewing window of the
combustion chamber
To clean the glass viewing window use gentle cleaning agents
(e.g. soapy water) and a soft cloth.
In adverse weather conditions or as a result of incorrect op-
eration or the use of unsuitable fuels the inside of the com-
bustion chamber window may become fogged. For cleaning,
please proceed as follows:
1. Open the combustion chamber door.
2. Lift the window glazing unit up and then carefully remove
it downwards. CAUTION: The glass protrudes at the top.
3. The middle glass pane can then be removed upwards.

Stoves with glass ceramic cooking surfaces
WHAT IS CERAN® ?
Glass ceramic cooking surfaces by SCHOTT of Mainz are ex-
tremely temperature resistant and withstand even abrupt tem-
perature shocks up to 750°C.
CERAN® is insensitive to normal mechanical loads in the
kitchen. The 4 mm thick glass ceramic is also highly perme-
able to heat. It allows radiation heat to pass almost without
loss, but hardly deflects any heat to the sides.
CERAN® cooking fields are easy to clean (please observe the
relevant information on Page 3 of the cleaning instructions
enclosed with the cooking field!) and make the play of the
flames visible.
CARE AND PRACTICAL TIPS FOR GLASS CERAMIC
COOKING PLATES
Clean your glass ceramic cooking field thoroughly before initial
use, then regularly while hand warm or cold. Avoid repeated
burning-in of dirt.
For cleaning we recommend:
• Kitchen paper towels or a clean cloth
• Razor blade scraper (Caution: only for the top! On no ac-
count must it be used to remove combustion residue from
the (rough) bottom of the plate as this would scrape off
irregularities – which in turn would result in scratches (“pre-
destined fracture points”).
• Commercially available glass ceramic cleaners.
The degree of dirt determines the choice of cleaning agents:
• Wipe light not burnt-in dirt with a moist cloth.
• All coarse and firmly adhering dirt is easily and comfortably
removed with the razor blade scraper; lime and watermarks,
grease splashes and metallic iridescent discolorations are
best cleaned with commercially available glass ceramic
cleaning agents.
All cleaning agent remains must be thoroughly wiped off moist
after every cleaning (even if instructions for use for cleaning
agents specify differently), since they could have a caustic ef-
fect when reheated. Follow-up by wiping dry. When correctly
used, the glass ceramic cooking surface will retain its attrac-
tive appearance. Please do not use any (usually too soft) aluminium pots on
your CERAN® cooking field! Since the glass ceramic is consider-
ably harder than most aluminium alloys, unsightly streaks may
form on the glass surface – which can hardly be removed once
burnt-in.
If anything has burnt-in on the cooking surface by mistake,
this must be removed immediately (while hot) with the razor
blade scraper to avoid surface damage.
• Damage through sugar or food containing sugar can be pre-
vented in anticipation by cleaning your glass ceramic cook-
ing surface either always or before preparing food with high
sugar content with Ceran® fix or Collo Profi. These agents
form a silicon film on the glass ceramic cooking surface
which does not only protect but also makes your cooking
surface even “smoother”, providing a water and dirt deflect-
ing quality. However, the silicon film is not resistant to high
temperatures such as occur in the cooking zones and must
be always reapplied.
What if...?
... a chemical cleaning agent alone is not sufficient?
Check to see if you will not serve the purpose must faster by
using the razor blade scraper.
... metallically looking discolorations appear in the cooking
zones over time?
Largely unsuitable cleaning agents were used. At this stage,
the discolorations can only be removed with difficulty using
Sidol®, alcohol or scouring pads.
... the surface has scratches or minor spalling?
These imperfections caused by scratching or melted-on items
cannot be repaired. However it does not impair the service-
ability of your stove in any way.
... dark stains have developed?
If cleaning with the razor blade scraper, Sidol®, alcohol or
scouring pads does not yield any improvement, it is prob-
ably abraded decoration caused through unsuitable cleaning
agents or the scouring action of pot bases.
Where to obtain the cleaning agents?
Glass ceramic cleaning agents are available in department
stores (electrical appliances department), electrical appliances
stores, pharmacies, grocery stores and kitchen studios.
• Never use abrasive or aggressive cleaning agents such
as grill and baking oven sprays, stain and rust remover,
scouring sands, sponges with abrasive surface.
• Scratches can also develop when for instance grains of
sand from the previous cleaning of vegetables are dragged
over the cooking surface while adhering to the pot.
• Pot and pan bases can have edges and burrs, which can
leave unsightly traces when pushed around or have an
abrasive effect on the glass ceramic surface. This applies
particularly to cast iron cooking utensils and enamel pots
with electrographitized base.
• Always place the pots on the stove with clean and dry
base. Avoid enamel cooking ware cooking dry.
• Keep away from the hot cooking surface any items that
can melt on, e.g. plastics, aluminium foil, especially sugar
and food containing plenty of sugar.

The interaction of several factors is required for trouble free stove operation:
Stove: correct installation connection and start-up.
Operation and care: according to the information in the user manual, regular cleaning of stove, flue gas pipe and chimne.
Chimney: correct dimensioning, perfect condition.
Fuel: use of recommended types of fuel in adequate quality and degree of dryness.
Weather: no stifling air in the chimney.
The following list shows possible faults, their causes and possible remedies:
COMBUSTION
JETIFIRE
JETIFIRE is the only system without blower and elaborate con-
trol electronics to offer a genuine output-dependent second-
ary air supply. With a large fire, lots of flue gas will flow
through the constriction in the front part of the fire compart-
ment. This results in an increased flow velocity which in turn
increases the suction effect; more preheated secondary air is
transported into the combustion chamber. The burning gases
subsequently flow through the JETIFIRE opening where they
collide with the bottom of the stove plate. This results in
intensive mixing of the combustible gases with the supplied
secondary air. The result: high-temperature combustion at ap-
proximately 950°C!
ADVANTAGES
• greatly reduced emission values
• shortened initial heating phase
The flame concentration plate is exposed to very high tempera-
tures and consequently high wear. The plate must be replaced
with a new one after several heating periods. In this context the
chimney draught plays an important role in the durability of the
JETIFIRE flame concentration plate. The stronger the chimney
draught, the shorter the service life. The JETIFIRE flame concen-
tration plate is available as a spare part directly from us.
• longer fuel adding intervals
• more efficient fuel utilisation
• reduced heating costs
With low output exactly the opposite takes place; smaller fire,
lower flow velocity, lower vacuum, less suction, less second-
ary air...”
Clean the JETIFIRE plate as well as the stove itself to remove
combustion residue from time to time.
